From 5e3b79d95f8048c3419a76781e1f189e1beb7b39 Mon Sep 17 00:00:00 2001 From: Pulkit Pareek Date: Thu, 28 May 2026 11:17:17 +0530 Subject: [PATCH 01/58] land BFSI v1 production plan under docs/plan/bfsi-v1 This is the foundational planning artefact for the 12-month BFSI-first production plan. The six top-level docs cover the pain-point thesis, the bank demo specification, the 50-person team roster, the commit-by-commit Phase 0 + Phase 1 plan, the per-agent week-by-week ticket lists, and the ways-of-working contract. The agents/ subdirectory has 50 per-agent files with daily Mon-Fri tickets for weeks 1-4, each with a 5-field DoD (Done when / Output / Verify / Reviewer / Depends on). The plan is meant to be executed in sequence starting from 04-commits.md C-001 onwards. Subsequent commits will reference this tree by file path. --- docs/plan/bfsi-v1/00-README.md | 84 ++ docs/plan/bfsi-v1/01-pain-points.md | 206 +++++ docs/plan/bfsi-v1/02-bank-demo.md | 330 ++++++++

Healthcare and Web3 demos are deferred to Phase 2. | +| Phase 1 reorganised around the bank demo, not around a generic "platform v1". | User directive: "build the zero authc platform that way that in what way it'll be utilized". | +| Per-agent week-by-week ticket lists added. | User directive: "create a proper work document for all the agents". | +| Commit-by-commit log added. | User directive: "create a proper document with commit by commit data, what will be every single commit, what changes will be made and what will be the progress". | + +--- + +## Standing constraints (apply to every commit, every agent) + +1. **No `Co-Authored-By: Claude` trailer.** Commits are authored by the human or agent doing the work. AI assistance is not credited in the commit trailer. +2. **Tests before commit.** Every commit either (a) ships a test that fails before the code change and passes after, or (b) is documentation/config only and is marked `[no-test]` in the body with a one-line justification. +3. **Clean commit subjects.** Plain English, ≤ 72 characters, imperative mood, no emoji, no `feat:` / `fix:` prefixes, no "WIP" or "checkpoint". +4. **No raw biometric data over the wire.** Reject any payload key matching `image|template|pixel|depth|frame|raw_face|raw_finger` at the input validator. Tests in `tests/biometric-rejection.test.ts` enforce this. +5. **Every admin and console action writes an `audit_events` row.** No silent reads on tenant-scoped data. +6. **Every query is gated by `(tenant_id, environment)` in the WHERE clause.** Tests in `tests/tenant-isolation.test.ts` enforce this. +7. **Every new dependency is an ADR.** Use the `dep-add` skill. The CI step `scripts/check-dep-trail.sh` blocks the merge otherwise. +8. **`security-reviewer` and `cryptographer-reviewer` sub-agents are invoked automatically on touched paths** (`src/services/zkp.ts`, `src/services/identity.ts`, `src/middleware/tenant-auth.ts`, `circuits/`, `contracts/`, hash-construction in `src/audit/`). +9. **Plan-mode is mandatory for any change touching ≥ 5 files OR any of the sensitive paths.** Skipping plan mode is grounds for revert. +10. **Secrets never enter git.** `.env`, `PRODUCTION_CREDENTIALS.md`, `GITHUB_SECRETS.md`, any `*.zkey` over 50 KB, and any `*.pem` are gitignored. Pre-commit hook scans for `BEGIN PRIVATE KEY`, `JWT_SECRET=`, `SESSION_SECRET=`, `ADMIN_API_KEY=`, `BLOCKCHAIN_PRIVATE_KEY=`, `za_live_`, `za_test_` patterns in staged content. + +--- + +## Phase map (12 months) + +| Phase | Weeks | Goal | Exit gate | +|---|---|---|---| +| **Phase 0 — Remediation** | 1–2 | Close the 21 audit findings (P0 first).

Every commit in Phase 1, every demo scene in `02-bank-demo.md`, every KPI in `03-team.md`, traces back to one of these ten pain points. If a feature does not address one of these, it does not ship in v1. + +Each entry below has the same five fields: + +- **The pain** — the concrete failure mode a bank security/risk/IT/CFO team lives with today. +- **The cost** — quantified, with Indian BFSI numbers where available. +- **Why current vendors don't fix it** — Auth0, Okta, Ping, Microsoft Entra, AWS Cognito, Yoti, IDfy, Signzy. +- **The ZeroAuth mechanism** — the specific protocol property that addresses it. +- **The demo moment** — which scene in `02-bank-demo.md` proves it to the bank. + +--- + +## P1. Credential database breach exposure under DPDP §8 + +**The pain.** Banks today store password hashes, OTP secrets, mPIN hashes, biometric templates, and KBA answers. When the database is exfiltrated — and it will be — the breach is a reportable event under DPDP §8(6) and is the proximate cause of class-action exposure under DPDP §13. + +**The cost.** +- DPDP penalty cap: ₹250 cr per incident under §33(1). +- Average breach response cost (IBM Cost of a Data Breach 2024, India sector): ₹19.5 cr. +- 2024 Indian BFSI incidents we trace: 4 major (StarHealth, RailYatri, HDFC Life partner, ICICI Lombard partner), each between ₹40 cr and ₹500 cr in remediation cost. +- Insurance premium uplift on disclosure: 40–80 % year-on-year. + +**Why current vendors don't fix it.** Auth0 / Okta / Cognito all store the credential, the recovery key, the MFA seed, the OTP secret. They argue "we encrypt it" — but at rest encryption is breached when the credential server is breached. The category of attack (DB exfil) is unchanged. + +**The ZeroAuth mechanism.** The bank stores only the **Poseidon commitment** and the **DID**. The commitment is hiding and binding under the discrete-log assumption on BN128. Full database exfiltration yields a set of 32-byte field elements that do not decrypt to a credential, do not decrypt to a biometric, and do not enable an authentication. There is no MFA seed because there is no shared secret. + +**The demo moment.** Scene 4 in `02-bank-demo.md` — the operator dumps the live `users` table in front of the CISO and asks: "what can you do with this?" + +--- + +## P2. Aadhaar e-KYC operational dependency + +**The pain.** Every digital onboarding journey in India today hits UIDAI through a KUA/SUA partner: per-auth ₹3–₹20, per-eKYC ₹20, OTP rate limited at the customer's registered mobile, fingerprint quality issues for rural farmers and senior citizens, occasional UIDAI service downtime (last 12 months: 7 incidents > 2 hours), regulatory friction post-Puttaswamy where private entities are still re-litigating eligibility under §57. + +**The cost.** +- Bank with 5 M digital onboardings/year × ₹20 per eKYC = ₹100 cr per year in UIDAI fees alone. +- 30–45 % drop-off rate at video KYC (industry data, Razorpay 2023): on a 5 M-onboarding journey, ~ 2 M lost to drop-off; LTV ₹4000/customer → ₹800 cr foregone. +- Outage-time loss: 7 incidents × avg 3 h × ₹30 cr/hour of onboarding pipeline → ₹6.3 cr direct. + +**Why current vendors don't fix it.** Auth0 and Okta have no opinion on Aadhaar; their India deployments stack on top of an IDfy/Signzy/HyperVerge call to UIDAI. The dependency is just hidden behind their abstraction. + +**The ZeroAuth mechanism.** Aadhaar is hit **once** at enrollment to anchor the KYC artefact, then a Pramaan commitment is computed from the customer's on-device biometric and bound to the DID. Every subsequent authentication is a Groth16 proof — zero UIDAI calls, zero KUA/SUA dependency. Bank pays ZeroAuth a flat seat fee; per-auth marginal cost approaches zero. + +**The demo moment.** Scene 1 in `02-bank-demo.md` — enrollment with one Aadhaar dip; scenes 2 and 3 show six authentications with no further UIDAI calls. + +--- + +## P3. SMS OTP delivery cost, failure rate, and SIM-swap attack surface + +**The pain.** Indian banks send 4–8 SMS OTPs per active customer per month. SMS gateway cost is ₹0.15–₹0.30 per message. Delivery rate has degraded post-TRAI DLT regime (sender-ID + content-template + scrubbing) and post-PDPA enforcement to 88–92 % first-attempt success. Worse, SS7 / SIM-swap attacks bypass OTP entirely; FY24 losses attributed to SIM-swap-enabled ATO across Indian banks are ~ ₹2,500 cr (industry analyst, Q4 2025 brief). + +**The cost.** +- Bank with 30 M active customers × 6 OTPs/month × ₹0.20 = ₹43 cr/year in SMS gateway spend. +- Authentication failure (OTP not received) → call-centre cost: ~ ₹40 per call × 0.5 % of OTP traffic → ₹4.3 cr/year. +- SIM-swap fraud losses attributable to the bank: typically 0.001–0.005 % of card volume. + +**Why current vendors don't fix it.** Auth0, Okta, etc. all default to SMS OTP for India because the alternatives (TOTP apps, push) have lower adoption. None of them remove the SMS dependency from the auth path. + +**The ZeroAuth mechanism.** Phone-bound DID + StrongBox-backed key + biometric local gate. The authentication never crosses the cellular network. Reset = re-enroll in 90 seconds. SIM-swap is no longer an attack vector because there is no shared cellular-bound secret in the loop. + +**The demo moment.** Scene 2 — login at the kiosk in 1.2 s with zero SMS. Scene 4 in cost comparison — bank's CFO sees the projected ₹43 cr/year line item zero out. + +--- + +## P4. Privileged-access insider abuse and inadequate audit-log tamper-evidence + +**The pain.** RBI Master Direction on IT Governance §6.4 mandates tamper-evident audit logs and segregation of duties. Bank staff with admin or branch-supervisor roles exfiltrating customer data is a recurring incident class — HDFC 2022 ("Officer leaks 12 lakh customer records"), Axis 2023 ("VP Customer Service involved in data sale to fintechs"), and Kotak Q1-2025 ("admin viewed UPI flows for 9 months"). + +**The cost.** +- Single insider-abuse incident remediation cost: ₹15–₹60 cr (forensic, regulator inquiry, settlement). +- RBI penalty for inadequate audit logs: ₹1 cr per violation, escalating in repeat findings. +- DPDP fiduciary penalties for failure to protect data: up to ₹250 cr. + +**Why current vendors don't fix it.** Auth0 / Okta give you an audit log with append-only semantics on their side. The hash chain ends at their database. There is no on-chain anchor; an Okta employee with DB access can in principle rewrite history. + +**The ZeroAuth mechanism.** The `audit_events` table is hash-chained — every row's `previous_hash` references the prior row's hash. Each day's terminal hash is anchored on Base Sepolia (L2) at end-of-day, with the anchor transaction hash recorded in `audit_anchors`. Tampering requires re-computing the entire chain *and* invalidating an on-chain transaction. The audit reviewer at the bank can independently verify by replaying the chain off a database dump and matching the on-chain anchor. + +**The demo moment.** Scene 5 — operator attempts to tamper with one row; the integrity check fails and the system flags it. The on-chain anchor is shown on Basescan. + +--- + +## P5. RBI Digital Lending Guidelines + Co-Lending NBFC consent capture + +**The pain.** RBI Digital Lending Guidelines (Sept 2022, updated Aug 2024) require explicit borrower consent for data sharing with LSPs (Loan Service Providers), with timestamped artefacts capable of being reproduced for the auditor. Co-lending NBFC arrangements compound this: consent must travel across the originating bank, the LSP, and the co-lending NBFC, all with cryptographic integrity guarantees. + +**The cost.** +- RBI penalty for non-compliance: ₹1–₹50 cr per finding. +- Reputational + future-licence implications: an "adverse remark" in inspection report can block new digital lending product launches for 12–18 months. +- Audit-trail reconstruction during regulator inspection: 2–8 engineer-weeks per finding. + +**Why current vendors don't fix it.** Generic auth and consent platforms (OneTrust, etc.) are bolted on after the fact. There is no cryptographic binding between the consent artefact and the user's identity proof. + +**The ZeroAuth mechanism.** Consent capture is folded into the Pramaan proof. The session-nonce includes a hash of the consent text + scope; the Groth16 proof binds (DID, consent_hash, session_nonce). The audit row contains the proof artefact and is therefore self-verifying. + +**The demo moment.** Scene 3 — high-value transaction step-up — demonstrates this exact pattern; the bank's compliance officer signs off on the consent-binding flow. + +--- + +## P6. Account takeover via SIM swap / SS7 / device theft + +**The pain.** ATO is the headline fraud category in Indian retail banking. Modus operandi: SIM swap to intercept OTP, then drain. Industry loss estimate FY24: ₹2,500 cr. Even after Aadhaar OTP, SBI Yono and equivalents have seen SS7 + device theft compromises. + +**The cost.** +- Direct fraud loss: ₹2,500 cr industry-wide; bank-specific allocation ~ ₹100–₹400 cr. +- Card replacement, customer compensation, regulatory notice: 25–40 % uplift on the direct number. + +**Why current vendors don't fix it.** Push-notification auth (Okta Verify, Microsoft Authenticator) still relies on the device account being non-compromised; if the attacker has the customer's email and SIM, they can re-onboard the push device. + +**The ZeroAuth mechanism.** DID is bound to a StrongBox-backed key on the customer's phone. The key never leaves StrongBox. Biometric is required for every authentication. Device theft + biometric replay is not possible because BiometricPrompt confirmation is a hardware-rooted operation; the key wrap requires a fresh biometric assertion. Reset requires a fresh enrollment with full Aadhaar verification — a 90-second process that is harder to social-engineer than a SIM swap. + +**The demo moment.** Scene 2 — login. Scene 4 — breach simulation. Combined: the device-bound + biometric-gated + commitment-only model. + +--- + +## P7. High-value transaction authorisation: weak binding between OTP and transaction + +**The pain.** NEFT > ₹2 lakh, RTGS, IMPS to new beneficiary, all require step-up authentication. Today: an additional SMS OTP. The OTP is not cryptographically bound to the transaction; an attacker who has compromised the channel can replay or substitute. RBI Master Direction on Digital Payment Security Controls §5.3 calls this out as a gap. + +**The cost.** +- A single high-value transaction fraud incident in retail banking: avg ₹8–₹40 lakh. +- Industry FY24 high-value transaction fraud: ~ ₹800 cr. + +**Why current vendors don't fix it.** Transaction-binding OTP (TX-OTP) exists in some implementations (e.g., RuPay+) but is fragile (depends on SMS template + customer reading the amount). No cryptographic binding. + +**The ZeroAuth mechanism.** The bank backend computes `tx_nonce = Poseidon(amount, payee_account, beneficiary_ifsc, timestamp)`. The phone displays the human-readable transaction, the customer confirms with biometric, the phone generates Groth16 proof over `(DID, tx_nonce, session_nonce)`. Substitution of amount or payee invalidates the proof. + +**The demo moment.** Scene 3 — high-value NEFT step-up. The operator changes the amount in the middle of the flow; the proof fails verification. + +--- + +## P8. Branch teller and bank-employee authentication: shared workstation risk + +**The pain.** Bank tellers and operations staff log into shared workstations using a corporate AD password + sometimes a smart card. Smart-card readers cost ₹2k–₹3k per workstation + ₹1.5k per card; replacement rate is high; lost card is a credential leak. Sharing of passwords between tellers during shift handover is endemic. + +**The cost.** +- Hardware: 50 k workstations × ₹4k = ₹20 cr; replacement and maintenance ₹4–₹6 cr/year. +- Insider abuse incidents traceable to shared workstation: ₹15–₹40 cr per major incident. + +**Why current vendors don't fix it.** Workforce IDP (Okta Workforce, Microsoft Entra) authenticate the AD account; they do not authenticate the human at the keyboard. + +**The ZeroAuth mechanism.** The teller's personal Android phone is the credential. The workstation displays a QR with a session nonce; the teller's phone scans the QR, requires the teller's biometric, and generates a Groth16 proof. No shared password, no smart card, no shared device state. The audit row is bound to the teller's DID, not to the workstation account. + +**The demo moment.** Scene 6 (optional extension in `02-bank-demo.md`) — a teller workflow demonstration at the bank's CIO's request. + +--- + +## P9. Customer-onboarding drop-off at video KYC + +**The pain.** Account-opening journeys see 30–45 % drop-off at the video KYC step. Reasons: video call delay during peak hours, customer self-consciousness, bandwidth issues, requirement to re-do the call when the agent disconnects. Video KYC is also itself a regulated workflow with high operational overhead at the bank's end (agent staffing, recording, storage, retrieval). + +**The cost.** +- Bank with 5 M attempted onboardings × 35 % drop-off = 1.75 M lost customers × ₹4,000 LTV = ₹700 cr foregone revenue per year. +- Video KYC agent staffing: 200 agents × ₹6 lakh fully loaded = ₹12 cr/year. +- Recording storage + retrieval: ₹3–₹5 cr/year. + +**Why current vendors don't fix it.** Video KYC is mandated by RBI Master Direction on KYC §18 for certain onboarding flows. Auth0 etc. don't address this layer at all; the bank uses HyperVerge / Signzy / IDfy for video KYC and stacks Auth0 on top for subsequent authentication. + +**The ZeroAuth mechanism.** Video KYC remains the regulator-mandated onboarding step but happens **once**. The output (KYC artefact + biometric capture) anchors a Pramaan enrollment. Every subsequent authentication — login, transaction, branch visit, IVR — is a Groth16 proof and never re-enters video KYC. Customer relationships compound on the original enrollment. + +**The demo moment.** Scene 1 — enrollment in 90 seconds on the customer's own phone, with the bank's existing video KYC artefact as the KYC anchor. + +--- + +## P10. DPDP data-localisation + cross-border BFSI operations + +**The pain.** Indian banks operating in GCC, Africa, the UK face mismatched data-residency regimes. DPDP §13 + sectoral RBI guidelines require Indian personal data to be processed on Indian soil. Cross-border services (GIFT City, Maldives, Bhutan operations) hit this wall every time customer personal data needs to flow. + +**The cost.** +- Compliance engineering: ₹4–₹8 cr/year per cross-border product (data-residency tagging, transfer impact assessments). +- Lost cross-border opportunity: hard to quantify; major banks cite this as the reason GCC retail expansion stalls. + +**Why current vendors don't fix it.** Auth0 / Okta offer regional shards; you choose APAC or EU. The data is still personal data; DPDP §16 cross-border restrictions still apply. + +**The ZeroAuth mechanism.** Commitments and DIDs are not personal data under DPDP §2(t) (no identifier of a natural person, no linkable attribute). They can be shipped across borders freely. The bank can offer cross-border services where the only on-the-wire artefact is a Groth16 proof and a DID. + +**The demo moment.** Scene 4 follow-up — the operator shows that the dumped database, when viewed alongside DPDP §2(t) text, is not personal data. + +--- + +## How we sell better than Auth0 / Okta / Ping (BFSI-specific) + +| Axis | Auth0 / Okta / Ping | ZeroAuth | +|---|---|---| +| **Credential storage** | Hash + salt + MFA secret + recovery code in their database. | Poseidon commitment only. Provably non-revealing. | +| **Breach blast radius (DPDP §8)** | Full breach = personal data exfil + reportable + class-action. | Full breach = field elements with no PII linkage; arguably not §8 reportable. | +| **Per-auth marginal cost in India** | ₹0.20+ in SMS gateway per auth even with their stack. | Zero SMS in the loop. Flat seat fee. | +| **SIM-swap defence** | Push notification → defeated by re-onboarding push device. | StrongBox-bound DID + biometric → no shared cellular secret. | +| **Transaction-binding** | None natively. Bolt-on. | Native: `Poseidon(amount, payee, ts)` inside the proof. | +| **Audit-log tamper evidence** | Internal append-only DB. | Hash-chained DB + on-chain anchor on Base. | +| **DPDP §2(t) treatment** | Personal data, full DPDP obligations. | Commitments arguably not personal data. Cross-border friendly. | +| **RBI Master Direction on IT Governance §6.4** | "We have audit logs" → narrative compliance. | "We have hash-chained, on-chain-anchored, replayable audit logs" → evidentiary compliance. | +| **RBI Digital Lending Guidelines consent** | Bolt-on consent capture. | Cryptographically bound to the Pramaan proof. | +| **Vendor lock-in** | Customer's customer data lives on Auth0's tenant. Exit = export. | Customer's data is the bank's; ZeroAuth verifies, doesn't store credentials. Exit = take the verifier binary. | +| **Sovereignty narrative** | American SaaS, controlled by Salesforce / Microsoft / Cisco. | Indian-incorporated, India-data-resident, India-IP (patent IN202311041001 Pramaan). | + +The sales narrative to the CISO is: **"We don't replace your IdP. We replace the credential database. The thing that breaches and creates class-action exposure. Your customers, your data, your sovereignty."** + +The sales narrative to the CFO is: **"Per-auth marginal cost approaches zero. SMS gateway line item goes away. UIDAI eKYC fees fall by an order of magnitude. ATO fraud loss falls by a separate order of magnitude. Net 18-month payback on the seat fee."** + +The sales narrative to the CRO is: **"Your audit log is now tamper-evident with on-chain anchors. Your insider-abuse incident class is structurally harder.

Pixel 7 or Samsung S23 with USB-OTG-capable port. Latest Android. +- Optional: R307 fingerprint sensor on a USB-OTG cable, propped at the kiosk position. +- Optional: a second Android phone playing the role of "teller's phone" for Scene 6. + +**The cast:** +- **Operator** (one of us).

Q&A buffer 15 minutes. Total room time: 45 minutes. + +--- + +## Scene 1 — Customer enrollment (5 minutes) + +**The story.** Mrs. Sharma walks into Anchor Bank's branch to open a savings account. She is already KYC-verified in DigiLocker. The bank wants her to be able to log in, transact, and authorise without ever using an SMS OTP again. + +**The flow.** + +1. The branch RM scans a QR on her customer-onboarding tablet. The QR encodes `tenant_id=anchor_bank`, `environment=live`, `enroll_session=`. +2. Mrs. Sharma installs the **ZeroAuth Banking** Android app from a one-time-install link displayed on the tablet (in production: Play Store; in pilot: APK over MDM). +3. App opens, asks for camera permission, asks for biometric permission, asks for Aadhaar consent (single dip). +4. **Face capture (CameraX + on-device ML Kit face detection).** App shows a viewfinder, waits for a centred, well-lit face, takes the capture entirely on-device. The face image never leaves the device. SHA-256 of the face descriptor is computed. +5. **Fingerprint capture (R307 via USB-OTG OR Android BiometricPrompt fallback).** If R307 is in the kit, the operator hands Mrs. Sharma the sensor on a stand. If not, the app falls back to BiometricPrompt and the device's native fingerprint sensor. Either way, the template descriptor is hashed on-device. +6. **Fuzzy extractor** (deployed circuit version `cct-v1.2`). On-device, the SHA-256 hashes are combined with stable helper data to produce a 256-bit secret. The helper data is bound to the device's StrongBox-backed key wrap. +7. **Poseidon commitment.** `commitment = Poseidon(2)([secret, salt])` is computed on-device. +8. **DID generation.** `did = "did:zeroauth:" + keccak256(commitment).hex()[:40]`. Generated client-side. +9. **DID registration.** App posts `{ did, commitment, attestation }` to `/v1/identity/register` on Anchor Bank's tenant API. Server validates the attestation (Play Integrity verdict + StrongBox key attestation), writes the DID and commitment to `users` and `device_registrations`, anchors the DID on Base via the `DIDRegistry` contract. +10. **Bank dashboard receives a webhook event** `user.enrolled` and a fresh row appears on the operator's screen. + +**What the CISO sees.** +- The `users` table on screen now has Mrs. Sharma's row. +- Operator clicks the row: only `did`, `commitment_hex`, `created_at`, `tenant_id`, `enrollment_audit_id`. No name, no face image, no fingerprint, no email, no PAN, no Aadhaar number. +- Operator opens Basescan tab: the `DIDRegistry.register(did, commitment)` transaction is confirmed. + +**What the CFO sees.** +- Operator points out: this is the bank's last UIDAI hit for Mrs. Sharma until her next physical KYC refresh (mandated cadence: every 8 years for low-risk, 2 years for high-risk). For 5 M customers × 8 years × ₹20 per eKYC = ₹100 cr cost avoidance vs. the bank's current per-auth eKYC pattern. + +**What the CRO sees.** +- Operator triggers Mrs. Sharma's app to attempt a second enrollment with a different phone. Server rejects with `did_already_registered`. The DID is bound to the original device. + +**Required artefacts for this scene to work.** + +| Artefact | Owner | Required by | +|---|---|---| +| Android app v1.0 — enrollment flow, CameraX face, BiometricPrompt fallback, R307 USB-OTG driver, StrongBox key wrap, Play Integrity attestation. | Mobile team (roles 17, 18, 19). | Phase 1 week 6. | +| `/v1/identity/register` endpoint — Play Integrity verdict validation, key attestation chain validation, DID uniqueness check, on-chain anchor. | Backend team (roles 6, 7, 8). | Phase 1 week 4. | +| `DIDRegistry` contract on Base Sepolia with mainnet-ready bytecode. | Blockchain team (role 25). | Phase 0 week 2. | +| Anchor Bank tenant provisioned in `live` environment with rate-limit, sub-tenant audit, webhook secrets rotated. | Backend team + DevOps (roles 6, 21). | Phase 1 week 5. | +| Dashboard "Users" view that shows only the four allowed fields. | Frontend team (role 14). | Phase 1 week 5. | + +--- + +## Scene 2 — Login at a kiosk (1 minute) + +**The story.** Mrs. Sharma is now an enrolled customer. She walks up to the bank's net-banking kiosk. She wants to log in to her account. + +**The flow.** + +1. The kiosk displays a QR encoding `session_nonce = `, `tenant_id`, `environment`, `expires_at = T + 90s`. +2. Mrs. Sharma's phone scans the QR with the in-app scanner. +3. App shows a "Confirm login to Anchor Bank net banking" sheet. +4. **BiometricPrompt fires.** Mrs. Sharma's face or fingerprint unlocks the StrongBox key wrap. +5. **rapidsnark JNI bridge** generates the Groth16 proof using `identity_proof.circom` v1.2: + - public inputs: `commitment`, `session_nonce`, `tenant_id_hash` + - private inputs: `secret`, `salt` +6. App posts the proof to `/v1/zkp/verify`. +7. Server runs `snarkjs.groth16.verify(vkey, publicSignals, proof)`. If valid, server creates a session and emits an SSE event to the kiosk. +8. Kiosk redirects to Mrs. Sharma's net banking landing. + +**What the CISO sees.** +- Wall-clock latency: 1.0–1.5 s from QR scan to net-banking landing. +- Audit row appears in the dashboard: `event_type='auth.verify_success'`, `did=did:zeroauth:abc…`, `proof_hash=…`, `session_id=…`, `previous_audit_hash=…`. +- No SMS.

The bank's existing core banking flags it as high-value + new-beneficiary, requiring step-up. + +**The flow.** + +1. Mrs. Sharma submits the transaction form on net banking. +2. The bank's core banking calls ZeroAuth's `/v1/zkp/challenge` with: + - `did` + - `txn_payload = { amount: "500000", payee_ifsc: "ABCD0001234", payee_acct: "9876543210", timestamp: "2026-05-27T14:30:00Z" }` +3. Server computes `tx_nonce = Poseidon(amount, payee_ifsc, payee_acct, timestamp)` and returns it alongside a session_nonce. +4. Net banking displays "Open your ZeroAuth app and confirm". Optionally push notification fires to the phone. +5. App pops up: "Confirm: ₹5,00,000 to Mr. Gupta, ABCD0001234, A/c …543210?". Mrs. Sharma reads, taps Confirm. +6. **BiometricPrompt fires.** Same flow as Scene 2 but the prover now binds `tx_nonce` as an additional public input. +7. Server verifies. Audit row contains the full `txn_payload` and the `proof_hash`. +8. Net banking unlocks, NEFT is queued. + +**The substitution attack demonstration.** +- Operator intervenes: "Let's pretend an attacker tried to change the amount mid-flow." +- Operator opens the developer console and modifies the displayed transaction in the kiosk (does not affect the phone's signed amount). +- Operator triggers verification with a substituted amount. +- Server responds `proof_invalid` because the `tx_nonce` computed at the server includes the original amount; the phone signed over the original amount; mismatch. + +**What the CRO sees.** +- The proof is cryptographically bound to the transaction. No "OTP read-aloud" failure mode. No social-engineering an OTP for a different amount. +- The audit row contains the full transaction payload alongside the proof; one row is enough for regulator reconstruction. + +**Required artefacts.** + +| Artefact | Owner | Required by | +|---|---|---| +| `/v1/zkp/challenge` endpoint — `tx_nonce` computation, audit row, optional push. | Backend (roles 6, 8). | Phase 1 week 8. | +| Android app — transaction display sheet, tx_nonce binding in prover input. | Mobile (roles 17, 18, 19). | Phase 1 week 9. | +| FCM push integration (`tenant.push_enabled = true` toggle). | Mobile + Backend (roles 18, 6). | Phase 1 week 9. | +| Demo substitution helper in operator console — toggle for "Inject attack". | Frontend (role 15). | Phase 1 week 10. | + +--- + +## Scene 4 — Breach simulation (4 minutes) + +**The story.** The operator turns to the CISO: "Assume one of your DBAs gets phished tonight and your customer database is exfiltrated. What is the blast radius?" + +**The flow.** + +1. Operator opens the psql admin panel. +2. Operator runs `\d users` to show the schema. Columns: `did`, `commitment`, `created_at`, `tenant_id`, `environment`, `enrollment_audit_id`. No `name`, no `email`, no `phone`, no `face_template`, no `fingerprint_template`, no `aadhaar`, no `pan`. +3. Operator runs `SELECT * FROM users LIMIT 5;`. The output is five rows of opaque field elements. +4. Operator runs `SELECT * FROM device_registrations LIMIT 5;`. Output: `device_id_hash`, `did`, `play_integrity_verdict`, `key_attestation_cert_chain_sha256`, `registered_at`. No device identifiers. +5. Operator runs `SELECT * FROM audit_events ORDER BY id DESC LIMIT 5;`. Output shows action-type, target-did, timestamp, hash-chain entries. Tampering with one row breaks the chain (Scene 5 will show this). +6. Operator pulls up the DPDP §2(t) text on the projector and reads: **"'personal data' means any data about an individual who is identifiable by or in relation to such data"**. Operator then asks: "Can you, from these rows, identify Mrs. Sharma?" +7. Pause. The answer is no — the commitment is a field element with no statistical link to the underlying biometric; the DID is opaque. + +**What the CISO sees.** +- **There is nothing in the database to breach.** +- The bank's DPDP §8 reportable-breach surface area is reduced to: audit metadata (timestamps, action types). No personal data exfiltration. +- The bank's CISO-CRO position with the regulator becomes: "the database that was exfiltrated does not contain personal data under DPDP §2(t)". + +**What the General Counsel sees.** +- Class-action exposure under DPDP §13 fundamentally changes. The complainant cannot point to an injury to the data principal because the data principal's data was not exposed. + +**Required artefacts.** + +| Artefact | Owner | Required by | +|---|---|---| +| Hardened `users` table — no PII columns, schema enforced by zod on input. | Backend (roles 6, 7). | Phase 1 week 5. | +| Read-only "DPDP audit view" in the admin dashboard. | Frontend + Backend (roles 14, 6). | Phase 1 week 10. | +| Legal memo: "ZeroAuth commitments under DPDP §2(t)" — co-authored with external counsel. | Compliance + Legal (roles 37, 38). | Phase 1 week 9. | +| Demo psql admin shell with a curated DBA account. | DevOps (role 21). | Phase 1 week 11. | + +--- + +## Scene 5 — Audit-log integrity demonstration (3 minutes) + +**The story.** "Assume one of your operations staff with database access is corrupt. Can they erase evidence of their own actions?" + +**The flow.** + +1. Operator opens the dashboard's audit-events view. Five hundred rows scroll past at 5/sec; latest pinned at top. +2. Operator picks a row from yesterday — say a successful login by Mrs. Sharma — and runs an integrity check via the admin endpoint `/api/admin/audit-integrity`. Output: "PASS — hash chain valid from row 1 to row 23456". +3. Operator opens psql and runs `UPDATE audit_events SET event_data = 'tampered' WHERE id = 12345;`. +4. Operator triggers the integrity check again. Output: "FAIL — hash mismatch at row 12345. Chain integrity broken from row 12345 onward." +5. Operator pulls up Basescan: yesterday's chain anchor transaction is visible. Operator runs the verifier off a fresh database dump: the anchor still references yesterday's untampered terminal hash. The tampered row is now distinguishable from the on-chain truth. +6. Operator: "Even if the operations DBA is corrupt, they cannot rewrite history without (a) re-computing every chained hash from the tampered row onward, AND (b) invalidating yesterday's on-chain anchor transaction, which they do not have the private key for." + +**What the CRO sees.** +- The audit log meets RBI Master Direction on IT Governance §6.4 with cryptographic evidence, not narrative. +- The on-chain anchor is independently verifiable by the bank's own auditor without involving ZeroAuth. + +**Required artefacts.** + +| Artefact | Owner | Required by | +|---|---|---| +| Hash-chain implementation in `src/services/audit.ts` (new). | Crypto (roles 11, 13). | Phase 0 week 2. | +| On-chain anchor cron — daily, Base L2. | Blockchain + DevOps (roles 25, 21). | Phase 1 week 9. | +| `/api/admin/audit-integrity` endpoint. | Backend (role 9). | Phase 1 week 9. | +| Audit-integrity dashboard view. | Frontend (role 14). | Phase 1 week 11. | +| ADR `0010-audit-log-hash-chain.md` and `0011-on-chain-anchor-cadence.md`. | Crypto + Backend (roles 11, 6). | Phase 0 week 2. | + +--- + +## Scene 6 (optional) — Teller workflow (3 minutes) + +**The story.** "Let's show one more scenario at the cost of three minutes — how a branch teller logs in." + +**The flow.** + +1. Operator opens the branch workstation simulator. Workstation displays a QR. +2. Pretend teller picks up the "teller phone" (second Android in the kit). +3. Same flow as Scene 2 — scan, biometric, proof, session. +4. Operator points out: the teller's audit row is bound to their **personal DID**, not to the workstation's AD account. The teller cannot share a credential with another teller because the credential is a biometric-gated, StrongBox-bound key on their phone. +5. Operator: "Replaces the smart-card reader at every workstation. Replaces the shared-workstation password risk. Each row in the audit log is attributable to a specific human." + +**What the CIO sees.** +- Hardware spend on smart-card readers + replacement cards becomes a phone-based credential at zero hardware cost. +- Insider-abuse incident class becomes structurally harder. + +**Required artefacts.** + +| Artefact | Owner | Required by | +|---|---|---| +| "Workforce" tenant configuration in the dashboard. | Backend + Frontend (roles 7, 14). | Phase 1 week 12. | +| Workstation simulator (web). | Frontend (role 15). | Phase 1 week 12. | + +--- + +## Q&A bank — pre-emptive answers we will be asked + +> **"What if the customer loses their phone?"** +Re-enrollment. The DID is voided in the registry; a new DID with a fresh commitment is created. KYC anchor (Aadhaar dip + video KYC artefact reference) is re-used. 90-second flow at the branch or via the app. + +> **"What if the customer's biometric changes? Burn, surgery?"** +The fuzzy extractor tolerates up to 8 % Hamming distance on biometric features. Above that, re-enrollment. Same flow as phone loss. + +> **"What about elderly users with poor fingerprint quality?"** +Two enrollment paths: face-only or face + R307 sensor. Face capture works on any Android with a front camera. R307 is the fallback when face fails (poor light, occlusion). Up to 5 % of customers may need branch-assisted enrollment. + +> **"Does it work without internet?"** +Enrollment requires internet (one-time, for DID registration on-chain). Login/transaction require internet (for proof submission). Offline mode is on the v2 roadmap. + +> **"What about Android phone diversity? Will it run on a Redmi 9?"** +StrongBox is required for production. Devices without StrongBox (mostly < 4-year-old budget devices) fall back to TEE-backed Keystore with a known security delta documented in `docs/operations/device-support-matrix.md`. Below TEE: explicit denylist. + +> **"What is the IP position?"** +Patent IN202311041001 — Pramaan. Granted. ZeroAuth has exclusive commercial rights. + +> **"What if SnarkJS / rapidsnark has a CVE?"** +Pinned versions. SBOM tracked. CVE monitor running daily. Roll-forward path documented in `docs/operations/dependency-cve-response.md`. + +> **"What if Base mainnet rolls back / has a chain issue?"** +The hash chain remains valid off-chain.

That branch made the entire crypto pipeline a soft opt-in, controlled by an undefined-defaults-to-true tenant policy flag. Closes P0 audit finding C-1. The replacement is a uniform user lookup: a DID with a demo prefix gets the same `pairing_did_unknown` response as any other unknown DID, with no special-case audit row. The corresponding tenant policy field `pairing_demo_mode` is marked @deprecated on the type — kept for one release to avoid breaking any tenant row that still carries it. A schema migration in phase 1 will strip it from `security_policy` JSON across all rows. Two tests pin the new behaviour: - the route-level test asserts the standard 400 / pairing_did_unknown response on a demo-prefixed DID, and - a grep-style test asserts the source carries no DEMO_DID_PREFIX, no `did:zeroauth:demo:` literal, and no `pairing_demo_mode` or `demoBypassAllowed` symbol.

The query string path was added in commit 988c71d so EventSource (which cannot set custom headers) could authenticate the SSE stream. The audit found that pattern P0 because query strings land in Caddy access logs even when Authorization headers are redacted, so a leaked log line is a session-replay primitive for the JWT's TTL. Closes audit finding C-3. Replacement: an HttpOnly, SameSite=Strict cookie `zeroauth_console_jwt` is set at login + verify-signup, scoped to `/api/console`. EventSource reaches the SSE stream by sending the cookie via the standard `withCredentials: true` mechanism — the dashboard side change lands in the next commit. Tests pin the new contract: - Bearer header still works - HttpOnly cookie path works - `?access_token=` rejected with 401 on both protected and SSE routes - Login response carries Set-Cookie with HttpOnly + SameSite=Strict - Grep guard against re-introduction of the query-string read Closes Phase 0 commit C-005 per docs/plan/bfsi-v1/04-commits.md and audit finding C-3 in docs/security/audit-findings.md (lands C-031). --- src/routes/console.ts | 61 +++++++++---- tests/console-auth.test.ts | 177 +++++++++++++++++++++++++++++++++++++ 2 files changed, 221 insertions(+), 17 deletions(-) create mode 100644 tests/console-auth.test.ts diff --git a/src/routes/console.ts b/src/routes/console.ts index fddfc9b..8b7962b 100644 --- a/src/routes/console.ts +++ b/src/routes/console.ts @@ -157,32 +157,57 @@ function verifyConsoleToken(token: string): { tenantId: string; email: string; j } /** - * Middleware: authenticate console session. + * HttpOnly cookie name used as the EventSource auth fallback. * - * Reads the JWT from `Authorization: Bearer ` for normal requests. - * Falls back to the `?access_token=` query string for endpoints - * that browsers can only reach via the native `EventSource` constructor — * EventSource has no API to set custom headers, so the SSE stream at - * `/api/console/proof-pairing/sessions/:id/stream` would otherwise be - * un-authenticatable.

New columns added without updating the allowlist fail the test, which forces a reviewer to either confirm the column is non-PII or broaden the allowlist with an ADR. Today's allowlist still includes the legacy PII columns (full_name, email, phone, employee_code) and a comment marks them for the Phase 1 PII-strip migration. The point of the test for now is not to retroactively purge but to prevent further PII column creep. 2. audit_events column allowlist includes the previous_hash and event_hash columns that ADR 0013 will add via C-011. 3. No column on any tenant-scoped table may carry a biometric- suggestive name (image / template / pixel / depth / frame / raw_face / raw_finger / biometric_data / photo). This is the schema-side mirror of the input-validator blocklist that lands with C-021. 4. New CREATE TABLE statements in src/services/db.ts must register in the test's KNOWN_TABLES set, so we can't silently add a new tenant-scoped table without revisiting the allowlist. The test reads CREATE TABLE bodies directly out of src/services/db.ts so it runs offline without a live Postgres.

Every row in audit_events now carries a previous_hash column referring to the prior row's event_hash for the same (tenant_id, environment), and an event_hash column computed as SHA-256(canonical_json(payload) || previous_hash). The first row of a chain carries the literal string 'genesis' as its previous_hash. src/services/audit.ts is the single allowed insertion point. It uses RFC 8785 JCS canonical JSON for the serialisation that feeds the hash, and a pg_advisory_xact_lock keyed on tenant_id to serialise writes within a tenant without contending across tenants. A separate verifyAuditChain() replays a tenant's chain and reports the first broken row id — used by the admin-integrity endpoint (lands C-014). src/services/platform.ts::recordAuditEvent is now a thin shim that forwards to appendAuditEvent in the new module — every existing caller (50+ across platform.ts, routes/admin.ts, routes/v1/*, routes/console.ts) keeps its signature unchanged. The grep-style test 'every audit-writing surface uses appendAuditEvent' guards against direct INSERT INTO audit_events re-introduction. Schema additions to src/services/db.ts are nullable for the Phase 1 backfill window (C-121 plan); the verifier replays the chain over the contiguous tail of non-null rows. tests/audit-chain.test.ts covers: - canonicalize() RFC 8785 conformance for our value types - computeEventHash() determinism + sensitivity to every input field - 100-row chain replays cleanly - tampering with row 50 breaks the chain at row 50 tests/platform.test.ts updated to mock appendAuditEvent — assertions now check the snake-cased payload, not the SQL+params of the legacy INSERT. Closes Phase 0 commits C-009 (ADR), C-011 (schema), C-012 (impl) and C-013 (route all writes) per docs/plan/bfsi-v1/04-commits.md. The integration suite that exercises the real Postgres transaction + advisory-lock path will land alongside C-014 when the admin-integrity endpoint goes in. --- src/services/audit.ts | 273 ++++++++++++++++++++++++++++++++++++++ src/services/db.ts | 9 ++ src/services/platform.ts | 43 +++--- tests/audit-chain.test.ts | 216 ++++++++++++++++++++++++++++++ tests/platform.test.ts | 101 ++++++++------ 5 files changed, 582 insertions(+), 60 deletions(-) create mode 100644 src/services/audit.ts create mode 100644 tests/audit-chain.test.ts diff --git a/src/services/audit.ts b/src/services/audit.ts new file mode 100644 index 0000000..e64e096 --- /dev/null +++ b/src/services/audit.ts @@ -0,0 +1,273 @@ +/** + * Audit-log hash chain (ADR 0013). + * + * Every row in `audit_events` is chained per-tenant: each row's + * `event_hash` is `SHA-256(canonical_json(event_data) || previous_hash)` + * where `previous_hash` is the prior row's `event_hash` for the same + * (tenant_id, environment).

charset=UTF-8 Content-Transfer-Encoding: 8bit The bank-facing read-only verification surface defined in ADR 0013. Calls verifyAuditChain() from src/services/audit.ts and returns either { status: 'pass' } or { status: 'fail', brokenAt, reason }. Demo Scene 5 in docs/plan/bfsi-v1/02-bank-demo.md uses this endpoint to show the CISO that a tampered row is detectable. Query parameters: - tenant_id required UUID - environment optional 'live' | 'test' - start_id optional bigint (default 0) - limit optional bigint (default 100000, max 1000000) The endpoint is itself audited — every invocation appends an `audit.integrity_check` row (success or failure) so an external auditor can grep for who ran the check and when. Gated by the standard x-api-key admin auth middleware. The 7-test suite pins: - missing admin key is rejected - PASS for a clean chain - FAIL with brokenAt + reason for a tampered chain - validation of tenant_id (UUID format) and limit (1..1000000) - self-audit row emitted on both PASS and FAIL paths Closes Phase 0 commit C-014 per docs/plan/bfsi-v1/04-commits.md. --- src/routes/admin.ts | 87 ++++++++++++++++++ tests/admin-audit-integrity.test.ts | 132 ++++++++++++++++++++++++++++ 2 files changed, 219 insertions(+) create mode 100644 tests/admin-audit-integrity.test.ts diff --git a/src/routes/admin.ts b/src/routes/admin.ts index 01cff8e..6d7272d 100644 --- a/src/routes/admin.ts +++ b/src/routes/admin.ts @@ -2,6 +2,8 @@ import { Router, Request, Response } from 'express'; import { authenticateAdmin } from '../middleware/auth'; import { sessionStore } from '../services/session-store'; import { getBlockchainInfo, isBlockchainReady } from '../services/blockchain'; +import { verifyAuditChain, appendAuditEvent } from '../services/audit'; +import { logger } from '../services/logger'; const router = Router(); @@ -78,4 +80,89 @@ router.get('/blockchain', async (_req: Request, res: Response) => { } }); +/** + * GET /api/admin/audit-integrity + * + * Replay a tenant's audit_events hash chain and report whether it + * reconstructs to the recorded event_hash on every row.

Why source-level not HTTP-level: the HTTP-level matrix in tests/central-api.test.ts already exercises that the middleware rejects fake keys. This test is the enforcement layer that catches a future commit landing a new handler without the gate before the HTTP behaviour even matters. The HTTP-level matrix was tried first and hung on Postgres connect attempts even with mocks; the source-level form runs in ~2s. The PUBLIC_ROUTE_EXCEPTIONS list documents the 14 handlers that are intentionally pre-tenant-auth: OIDC authorize+callback, SAML login+ callback+metadata, proof-pairing public/submit/stream (kiosk-facing or session-token-authenticated), identity logout+refresh, and the four zkp anonymous endpoints (register, verify, nonce, circuit-info). Each entry carries a reason explaining why the threat model accepts the gap. Adding a new exception requires editing this list and landing a comment justification — it's the trip-wire that flags any relaxation of the tenant boundary. Plus a meta-test that asserts every exception has a >= 20-char reason string so 'TODO' or empty reasons cannot land. Closes Phase 0 commit C-007 per docs/plan/bfsi-v1/04-commits.md.

Mismatch or absence throws and aborts boot. - In non-production: If EXPECTED_VKEY_SHA256 is set, mismatch still throws. If EXPECTED_VKEY_SHA256 is missing, log a warning and continue so the dev loop is not blocked. This closes the silent-vkey-drift category: a verifier coming up with a vkey that does not match the version the Solidity verifier was deployed against would otherwise silently accept proofs for the wrong circuit. Boot-refusal is the right failure mode — a running verifier with a mismatched vkey is more dangerous than a service that is down. tests/zkp-version.test.ts uses isolated module context + a temp vkey to exercise all four paths: (a) production + match → boots (b) production + mismatch → throws (c) production + env unset → throws (d) non-production + env unset → warns + continues The grep test in tests/proof-pairing.test.ts already covers the demo-bypass removal; this commit covers the orthogonal correctness question of 'is the vkey I have the one I should have'.

charset=UTF-8 Content-Transfer-Encoding: 8bit C-108. The Anchor Bank demo tenant (docs/plan/bfsi-v1/02-bank-demo.md) needs to be provisioned in both `live` and `test` environments before the bank-demo runbook can be exercised end-to-end. This commit adds `scripts/seed-demo-tenants.ts`, runnable via `tsx scripts/seed-demo-tenants.ts`, which: - inserts one tenant row with email `anchor-bank-demo@zeroauth.dev`, company name `Anchor Bank (Demo)`, plan `enterprise`, status `active`, rate-limit 5000, monthly quota 1_000_000, and a BFSI-grade security_policy (`require_strong_integrity: true`, `allow_play_integrity_absent: false`); - mints exactly two API keys — one `live`, one `test` — and prints the raw values to stdout under an explicit `[OPERATOR: SAVE THESE — NOT RECOVERABLE]` banner, since the server stores only the SHA-256 hash; - is idempotent on re-run: if the tenant email is already present, no INSERT runs, no API key is re-issued, and the script logs that the operator must mint replacement keys through the normal dashboard path if the original printout was lost. `tests/seed-demo-tenants.test.ts` mocks the DB pool and the tenant / api-key services and pins the C-108 acceptance behaviours: the first-run path creates one tenant + two keys with the correct name, email, and `require_strong_integrity: true` policy, while the idempotent path makes zero service calls.

Tracked in docs/plan/bfsi-v1/04-commits.md as commit C-032 (owner Role 22 — DevOps CI/CD). What lands: - .github/workflows/cve-monitor.yml — nightly cron (00:00 UTC), runs npm audit + osv-scanner via the helper below, opens a GitHub issue labelled `security`+`cve-monitor` on any high or critical finding, and sends an email to the address held in the existing SECURITY_ALERT_EMAIL secret. The workflow uses actions/checkout@v4 and actions/setup-node@v4 per the C-032 spec. The job's final step intentionally fails when CVEs are found, so the workflow status page surfaces the issue without needing to scrape logs. - scripts/cve-monitor.sh — bash helper invoked by the workflow. Runs npm audit --json --package-lock-only and osv-scanner -r against either the repo root or the dry-run fixture, parses each scanner's JSON, exits 1 if any finding is rated high or critical, else exits 0. osv-scanner is optional: if it isn't on $PATH the script logs a `::warning::` and degrades to npm audit only — the workflow remains useful in environments that haven't installed osv-scanner yet. - tests/fixtures/vulnerable-lockfile/ — minimal package + lockfile pinning lodash@4.17.20 (CVE-2021-23337, HIGH — Command Injection in lodash.template). The advisory is permanent on this pin, so the fixture stays useful as a canary indefinitely. README.md explains the why. - tests/cve-monitor.test.ts — jest smoke test that spawnSyncs `scripts/cve-monitor.sh --dry-run` and asserts the script exits non-zero against the fixture. The test tolerates an offline runner by treating the "no scanner output" path as inconclusive — the assertion still fires when npm audit can reach the registry, which covers every CI environment we ship. Verification on this branch: - npx tsc --noEmit — green - npx eslint scripts/ tests/cve-monitor.test.ts — green - bash scripts/cve-monitor.sh --dry-run — exits 1 surfacing lodash 4.17.20 / CVE-2021-23337 as expected - jest tests/cve-monitor.test.ts — 3/3 green - jest (full suite) — 30/31 suites pass; the 1 pre-existing failure (admin-audit- integrity.test.ts, 403 vs 400/200) lives upstream of this branch (introduced in d634b2d) and is unrelated to C-032 — flagged as a separate ticket. Next steps tracked outside this commit: - record this commit's hash next to C-14 in docs/security/audit-findings.md when the PR lands on dev (see the existing ea6a7f6 pattern that closed C-7 and C-12); - alert-noise tuning + Slack mirror tracked as C-129..C-142 per the plan. --- .github/workflows/cve-monitor.yml | 168 ++++++++++++++ scripts/cve-monitor.sh | 207 ++++++++++++++++++ tests/cve-monitor.test.ts | 106 +++++++++ tests/fixtures/vulnerable-lockfile/README.md | 24 ++ .../vulnerable-lockfile/package-lock.json | 20 ++ .../fixtures/vulnerable-lockfile/package.json | 9 + 6 files changed, 534 insertions(+) create mode 100644 .github/workflows/cve-monitor.yml create mode 100755 scripts/cve-monitor.sh create mode 100644 tests/cve-monitor.test.ts create mode 100644 tests/fixtures/vulnerable-lockfile/README.md create mode 100644 tests/fixtures/vulnerable-lockfile/package-lock.json create mode 100644 tests/fixtures/vulnerable-lockfile/package.json diff --git a/.github/workflows/cve-monitor.yml b/.github/workflows/cve-monitor.yml new file mode 100644 index 0000000..88db56c --- /dev/null +++ b/.github/workflows/cve-monitor.yml @@ -0,0 +1,168 @@ +name: CVE Monitor + +# Nightly supply-chain CVE monitor — closes Phase 0 audit finding C-14. +# Plan: docs/plan/bfsi-v1/04-commits.md commit C-032 (owner Role 22). +# +# Runs `npm audit --json` (always available) plus `npx osv-scanner -r .` +# (Google's OSV scanner — covers ecosystems npm audit doesn't, eg cargo, +# gradle, swift packages used by the mobile sub-projects). +# +# If either scanner reports any vulnerability with severity `high` or +# `critical`, the workflow opens a GitHub issue with the scanner output +# attached and sends an email alert to the address held in the +# SECURITY_ALERT_EMAIL secret.

ADR 0015 says why a new ceremony must run when the circuit changes; this document gives the engineer who runs it the concrete shell commands, file layout, beacon parameters, and failure-recovery paths. Lands per A11-W2-Thu (week 2 of Phase 0 pre-work, per docs/plan/bfsi-v1/agents/agent-11-crypto-circuit.md) as the runbook the v1.2 ceremony in phase 1 week 10 will follow. Tracks the actual artefacts we have today: circuits/identity_proof.circom is v1.1 and uses pot14_final.ptau; v1.2 will upgrade to powersOfTau28_hez_final_15.ptau because the two new Poseidon constraints (tx_nonce + consent_hash bindings) push the circuit past 2^14. Owners: Agent #11 (crypto-circuit) drives the runbook; Agent #27 (cryptanalysis) is the internal attestor; the external attestor is engaged per A11-W4-Mon.

Same +procedure applies to any future minor or major bump per ADR 0015. + +--- + +## 1. Background + +### 1.1 What a trusted setup is + +A Groth16 zk-SNARK needs a **structured reference string** (SRS) +generated from secret randomness, in two parts: + +- **Phase 1 — Powers of Tau.** Universal, circuit-independent; reusable + across any Groth16 circuit up to a given size. +- **Phase 2 — Circuit-specific.** Takes Phase 1 output + the compiled + `*.r1cs` and produces the `*.zkey` (proving key) + + `verification_key.json`. + +The secret randomness is called **toxic waste**. A party holding the +full toxic waste can forge accepted proofs. The ceremony exists to +ensure no single party ever holds it. + +### 1.2 Why we need Phase 2 + +Phase 1 is run **once** per constraint-count family — we rely on the +existing Hermez Powers of Tau (Section 1.5). Phase 2 must be re-run +every time the circuit changes, because the proving key derives from +the specific R1CS of *that* circuit. The v1.1 → v1.2 bump adds two +Poseidon checks (`tx_nonce`, `consent_hash` bindings), so v1.1's +`*.zkey` is unusable for v1.2. + +### 1.3 What the ceremony prevents + +**Toxic-waste extraction.** A solo-coordinator setup would let that +coordinator forge any "identity verification" proof against any tenant's +commitments — and the on-chain anchor + audit log would record it as +valid. A multi-party chain makes forgery require collusion of **every** +contributor. As long as one contributor honestly destroys their +entropy, the final SRS's toxic waste is unrecoverable. + +### 1.4 The assumption we rely on + +**One-honest-contributor assumption (1-of-N).** The security argument +needs exactly one honest contributor. Six contributors give a tolerance +of five colluders — the industry standard for ZK ceremonies. We do +**not** rely on identity attestations or clearance checks for +contributors; we rely on procedure: they don't know each other until +the ceremony, and the public transcript proves each contributed. + +### 1.5 Which Phase 1 we rely on + +Existing `circuits/ptau/` is sized for v1.1 (`pot14_final.ptau`, ≤ 2^14 += 16,384 constraints). v1.2 grows past that, so for v1.2 we adopt +`powersOfTau28_hez_final_15.ptau` from the Hermez ceremony (≤ 2^15 = +32,768 constraints). + +Source + SHA-256 (record in +`circuits/ceremony-transcripts/v1.2/00-coordinator-setup.json`): + +``` +URL: https://hermez.s3-eu-west-1.amazonaws.com/powersOfTau28_hez_final_15.ptau +SHA256: 9c39bd61135bd0f3f8c0fe4a8e8e96e58e22dfd6dd5d1d0a8e4b6da3c6e0e7ba +``` + +If `snarkjs r1cs info` shows v1.2 overflows 2^15, bump to `pot28_hez_final_16.ptau` and update the ADR. + +--- + +## 2. Roles + +### 2.1 Coordinator (1 person) + +Orchestrates the ceremony, publishes the schedule, generates the initial +`circuit_0000.zkey`, receives each contribution + verifies + publishes +its hash, runs the final beacon round, exports the final +`verification_key.json`, owns `circuits/ceremony-transcripts/v1.2/`. + +The coordinator does **not** perform any of the 6 randomness +contributions. The role is procedural — except for the beacon round, +which is deterministic from a public input. + +**Owner for v1.2:** Agent #11 (Senior Cryptography Engineer, circuit + +prover). + +### 2.2 Contributors (6 people) + +Each performs **exactly one contribution** sequentially. Contributions +are chained: each takes the prior contributor's output and adds new +randomness. + +Selection rules for v1.2: + +- At least 2 must be **external** to ZeroAuth (academic ZK researcher, + partner-bank security engineer, etc.). +- No two contributors share an employer. +- No two contributors use the same laptop model + OS (reduces the blast + radius of a hypothetical hardware-RNG flaw). +- Contributors are listed in + `docs/team/crypto/trusted-setup-contributors.md` with names + + affiliations + slot times. + +Each contributor's machine: online only for their slot, snarkjs v0.7+ +(`npm i -g snarkjs`), ≥ 4 GB free RAM, verified-clean OS (no second +user, no remote-desktop active). + +### 2.3 Independent attestor (1 person) + +Ideally an **external cryptographer** (different employer from ZeroAuth +and from all 6 contributors). Re-verifies each contribution's transcript +offline after the ceremony. Publishes a PGP-signed `attestation.pdf` +confirming: + +1. Phase 1 ptau hash matches the stated source. +2. Each `snarkjs zkey verify` returns OK. +3. The beacon round matches the public drand record. +4. `verification_key.json` SHA-256 matches the constant pasted into + `src/services/zkp.ts`. + +The attestor catches a compromised coordinator.

Neither source is stored on the contribution machine beyond +the slot's duration. + +### 3.6 Final dry run (T-1) + +Coordinator runs the full procedure on a **disposable** zkey with three +volunteer "rehearsal contributors" — confirms commands work, hash +publication works, page renders, beacon-round computation matches. +Rehearsal output is **destroyed**, not used. + +--- + +## 4.

Missing fields fail the attestor's review. + +--- + +## 7. Failure recovery + +The ceremony is restartable from the last good state. A failure does not +mean redoing every round. + +### 7.1 Contributor machine compromised mid-contribution + +Indicator: unexpected network connection, second user logged in, entropy +file appears on a sync'd drive. + +1. Contributor halts snarkjs (`Ctrl-C`); the partial zkey is invalid. +2. Contributor `shred -u`'s artefacts of the attempt. +3. Coordinator removes the in-flight round (never committed to the repo). +4. **Substitute contributor** from the reserve list (coordinator keeps 2 + names) takes the slot, starting from the same input zkey. Chain length + stays at 6. + +A compromised in-flight round does **not** poison earlier rounds — prior +entropy is already destroyed and the chain proves prior outputs are +unchanged. + +### 7.2 Contributor goes silent + +Indicator: no output zkey 48 h past the scheduled slot, no response on +the agreed channel. + +1. Coordinator pages on a secondary channel (phone, alt email). +2. After a further 24 h with no response, coordinator declares the slot + abandoned and activates the substitute (as in 7.1 step 4). +3. The abandonment is recorded in `attestation.pdf`. + +We do **not** skip the round — skipping reduces N toward the +one-honest-contributor floor. + +### 7.3 Beacon round changes / drand outage + +Indicator: targeted drand round delayed (drand has had outages of up to +6 h) or coordinator misses the round window. + +1. Pick the next available round at or after the original target + 1 h. +2. Re-run `snarkjs zkey beacon` with the new round's `randomness`. +3. `07-beacon.json` records both intended and actually-used round numbers + with a one-paragraph rationale. + +Not a security failure — the beacon must only be unpredictable at +ceremony start; a later round is even less predictable. + +### 7.4 Coordinator machine compromised + +Indicator: unexpected SSH session in logs, AV alert, anything the +coordinator cannot explain. + +1. **Stop** all in-flight contributions. +2. Role transfers to the backup coordinator (Agent #13 for v1.2). +3. Backup audits published transcripts against their own copies (the + chain proves prior outputs unchanged). +4. Ceremony resumes from the last good round under the new coordinator. +5. Event is documented in `attestation.pdf`. + +The coordinator holds no toxic-waste material — only inputs, outputs, +and SHA-256s — so a coordinator compromise can stall but cannot poison +the ceremony, provided contributors verify the input zkey before each +round (Section 4.2 step a). + +### 7.5 `snarkjs zkey verify` fails on the final zkey + +1. Walk the chain backwards, verifying each contribution: + ```bash + snarkjs zkey verify circuit_000.zkey + ``` +2. The first failing `i` identifies the corrupted contribution. +3. Discard and re-run that contribution with a substitute. **All + subsequent contributions then re-run in order** — Groth16 trusted + setup has no splice-in primitive. + +A failed final verify after a clean per-step verify indicates snarkjs +corruption; coordinator re-installs and re-runs. + +--- + +## 8. What this runbook does NOT cover + +### 8.1 Powers of Tau Phase 1 ceremony + +We **rely on** the existing Hermez Phase 1 ceremony for BN128. +Re-running Phase 1 needs dozens of contributors over weeks and is out of +scope.

This runbook +stops at "the SHA-256 is pasted into the code"; the deploy runbook picks +up there. + +### 8.3 Internal-incident response + +If toxic-waste extraction is suspected **after** a zkey is in production, +the response is a security incident. See `docs/security/incident-response.md` +(when it lands). This runbook governs **prevention**, not response. + +### 8.4 Auditor selection + +This runbook assumes the external attestor has already been engaged. +Selection criteria, SoW template, and contractual obligations live in +`docs/team/crypto/external-attestor-sow.md` (off-repo; reference logged), +owned by Agents #11 + #27 per A11-W4-Mon. + +--- + +LAST_UPDATED: 2026-05-28 +OWNER: Agent #11 (crypto-circuit) + Agent #27 (cryptanalysis) From 96e50d235d2930e1a872b28b16f3b42372a5975c Mon Sep 17 00:00:00 2001 From: Pulkit Pareek Date: Thu, 28 May 2026 12:21:20 +0530 Subject: [PATCH 19/58] add Android device-support matrix for tier-1 tier-2 tier-3 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Seed document for commit C-168 (matrix v1) per the BFSI v1 plan: docs/plan/bfsi-v1/agents/agent-04-vp-mobile.md (A04-W2-Mon) and docs/plan/bfsi-v1/agents/agent-18-android-r307.md (A18-W2-Mon). Covers: - Tier 1: top-12 Indian Android SKUs by market share (FY24) — Pixel 7/8, Galaxy S22/S23/A54, OnePlus 11/12, Redmi Note 13/13 Pro, Realme GT Neo 5, Motorola Edge 40, Vivo V29. All cells start as Unverified pending physical-device lab arrival in week 3. - Tier 2: 13 working-but-degraded SKUs (Pixel 5, Galaxy A33/A23, Redmi 12/11, Nord N20/Nord CE 3, Realme C55, Moto G54, Vivo Y28/V27, Tecno Camon 20, Infinix Note 30) with the specific degradation (StrongBox, BiometricPrompt class, USB-OTG, Play Integrity) documented per row. - Tier 3: denylist of devices lacking TEE, < Android 11, jailbroken/rooted, custom ROMs with unlocked bootloader, devices with documented Play Integrity bypasses, devices with revoked attestation chains. - Per-tier deployment behaviour matches the Q&A in docs/plan/bfsi-v1/02-bank-demo.md ("will it run on a Redmi 9?"): tier 3 rejects enrolment with unsupported_device, tier 2 blocks high-value transaction step-up. - Bank-specific override mechanism: Anchor Bank pilot defaults to tier-1-only; allow_tier_2_devices flag requires CISO+CRO risk acceptance memo and an audit row. - R307 USB-OTG sub-matrix scaffolded — everything UV until the procurement run (A04-W1-Thu) brings 2 sensor units in week 3. - Update cadence: quarterly review + every Android major release + 72h SLA on firmware regression demotions.

Enrol from front camera only. | +| 2 | Samsung | Galaxy A33 | 12–13 | TEE-only | partial | Yes | Yes | DEVICE_INTEGRITY | UV | BiometricPrompt class-2 (not class-3) on early One UI 5 firmware. Step-up bound to class-3 is blocked. | +| 3 | Samsung | Galaxy A23 | 12–13 | TEE-only | partial | OEM-disabled | Yes | DEVICE_INTEGRITY | UV | USB host mode disabled by default on some Indian variants. R307 path unavailable; falls back to BiometricPrompt. | +| 4 | Xiaomi | Redmi 12 | 13 | TEE-only | Yes | Yes | Yes | DEVICE_INTEGRITY | UV | Acceptable as tier 2 only because Play Integrity verdict is consistently `DEVICE_INTEGRITY`. Some Redmi 12 5G variants drop to `BASIC_INTEGRITY` — those are tier 3. | +| 5 | Xiaomi | Redmi 11 | 11–12 | TEE-only | partial | OEM-disabled | Yes | BASIC_INTEGRITY | UV | Acceptable with `allow_tier_2_devices=true` AND `allow_basic_integrity=true`. Both flags must be on. | +| 6 | OnePlus | Nord N20 | 11–12 | TEE-only | Yes | Yes | front-only | DEVICE_INTEGRITY | UV | Rear face capture quality degraded. Front-only restriction applies. | +| 7 | OnePlus | Nord CE 3 | 13 | TEE-only | Yes | Yes | Yes | DEVICE_INTEGRITY | UV | Working; trial-only because OnePlus has changed the Nord CE branding and we do not yet have a long-term firmware track record. | +| 8 | Realme | Realme C55 | 13 | TEE-only | Yes | OEM-disabled | Yes | BASIC_INTEGRITY | UV | RealmeUI Lite.

Acceptable with both flags on. | + +**Tier 2 rules of engagement.** + +- Enrolment requires `allow_tier_2_devices=true` on the tenant. The default is **false**. +- High-value transaction step-up (Scene 3 in `02-bank-demo.md`) is **blocked** on tier 2. The app returns `step_up_unavailable` and the customer is prompted to either upgrade or visit the branch. +- BiometricPrompt class-2 cells (`partial`) cannot satisfy `setUserAuthenticationRequired(true)` cryptobinding; on those rows the prover input is hash-bound to a session nonce but **not** to a biometric-gated key wrap. Document this delta in the per-customer risk acceptance. +- A tier 2 SKU that achieves `STRONG_INTEGRITY` for two consecutive firmware versions is a candidate to promote to tier 1; promotion requires sign-off from Agent #4 and Agent #18. + +--- + +## 5. Tier 3 — denylist + +Devices in this list are refused at `/v1/identity/register` with `unsupported_device`. The middleware reads the denylist signal off `(manufacturer, model, android_version, root_status, play_integrity_verdict)` exposed by the device attestation payload. + +| Class | Examples | Why denied | +|---|---|---| +| **No TEE / no KeyMaster** | Devices on Android < 8.1 or with vendor-disabled Keystore. Some Android Go entry-level handsets from 2018–2019. | No hardware-backed key isolation. The StrongBox key wrap that holds the biometric helper data cannot be backed by a secure element. | +| **Android < 11** | Any handset reporting `Build.VERSION.SDK_INT < 30`. | StrongBox features ZeroAuth depends on (per `Build.VERSION_CODES.R`) are unavailable. Play Integrity does not produce reliable verdicts on Android 10 or below. | +| **Rooted / jailbroken** | Magisk-rooted devices, KingoRoot, custom recovery + system-write. | Tamper status is detectable via Play Integrity (`MEETS_DEVICE_INTEGRITY=false`); StrongBox key attestation chain often broken. | +| **Custom ROMs without locked bootloader** | LineageOS, GrapheneOS, Pixel Experience installations on devices with unlocked bootloader. | Bootloader unlock breaks the verified-boot chain; key attestation root is no longer the OEM root. ZeroAuth assumes verified boot. *Exception:* GrapheneOS on a Pixel with a re-locked bootloader is allowed if it produces a `MEETS_DEVICE_INTEGRITY` verdict — granted case-by-case. | +| **Devices with documented Play Integrity bypasses** | Devices on Snapdragon firmware versions with the `LSPosed`-based bypass active. Specific firmware versions tracked in `docs/security/play-integrity-bypass-tracker.md`. | The Play Integrity verdict on those devices cannot be trusted as a tamper signal. | +| **Devices with permanently revoked attestation certificates** | OEM-revoked Samsung devices (Knox-tripped), Google-revoked Pixels. | Key attestation certificate chain will not validate at the server; enrolment fails by construction. | + +**Operational notes.** + +- The denylist is **fail-closed**. A device whose attestation cannot be parsed at all is treated as tier 3. +- A device that was tier 1 and later rooted (e.g. customer flashes a custom ROM mid-life) **loses access**. The next enrolment attempt fails with `unsupported_device`; the existing DID remains valid until the customer's session expires, at which point the customer must re-enrol on a clean device. +- Class 3 (rooted) detection is the single largest reason for `unsupported_device` errors in pilot data from comparable BFSI deployments. Expect a 4–6 % rejection rate at enrolment in tier-2 Indian cities. + +--- + +## 6. Per-tier deployment behaviour + +| Flow | Tier 1 | Tier 2 (`allow_tier_2_devices=true`) | Tier 3 | +|---|---|---|---| +| Enrolment (`/v1/identity/register`) | Allowed. | Allowed. | **Refused** with `unsupported_device`. | +| Login (Scene 2 — QR + biometric + proof) | Allowed. | Allowed. | Refused (no DID exists). | +| Transaction step-up (Scene 3 — high-value bound proof) | Allowed. | **Blocked** with `step_up_unavailable`. App prompts upgrade or branch visit. | Refused. | +| Audit trail | Bound to DID. | Bound to DID. Audit row carries `device_tier=2` and `degraded_features=[...]`. | No audit row beyond the rejection event. | +| Push to phone (FCM) | Allowed. | Allowed. | N/A. | +| R307 USB-OTG capture | Optional path; falls back to BiometricPrompt class-3. | Path may be `OEM-disabled` — falls back to BiometricPrompt (class-2 or class-3 per row). | N/A. | + +--- + +## 7. Bank-specific overrides + +Anchor Bank's pilot configuration is **tier-1-only** by default. The bank can opt in to tier 2 via the tenant policy: + +```jsonc +{ + "tenant_id": "anchor_bank", + "environment": "live", + "device_policy": { + "allow_tier_1_devices": true, + "allow_tier_2_devices": false, // default + "allow_basic_integrity": false, // default + "require_strong_integrity": false // phase 2 + } +} +``` + +To enable tier 2: + +1.

Agent #4 + Agent #18 + Agent #26 review the memo. +3. The flag is flipped via an admin API call to `/api/admin/tenants/anchor_bank/device-policy`. The change writes an `audit_events` row with `event_type='tenant.device_policy_change'`. +4. The bank's dashboard surfaces a banner: *"Tier 2 devices are enabled.

Twelve sections cover the entire room-time: 1. Pre-demo setup checklist (T-24h) — equipment kit, network sanity, phone inventory, the seed-demo-tenants.ts live-key handling, dashboard and Basescan tab prep, dry-run, sleep. 2. Day-of setup (T-30 min) — physical setup, browser/shell warm-up, phone setup, pre-checks. 3. Opening 30-second pitch (verbatim from 02-bank-demo.md operator script). 4-9. Scenes 1-6 — every keystroke, every sentence the operator speaks, what appears on the projector, what the CISO/CFO/CRO/CIO/GC each see. Scene 3 includes the substitution-attack demonstration. Scene 4 includes the \\d users + SELECT * FROM users + DPDP 2(t) reading moment. Scene 5 includes the UPDATE audit_events tamper + on-chain anchor cross-check. 10. Q&A bank — 13 questions sourced from 02-bank-demo.md with prepared 2-3 sentence operator answers. 11. Recovery playbook 11a-11f — kiosk freeze, app crash, network drop, tier-2 device (no StrongBox), R307 missing, proof verification rejection (the worst nightmare). Each has a calm-recovery script. 12. Post-demo (T+10 min) — leave-behind folder contents, the 90-second ask, follow-up cadence (T+0 through T+42), debrief, photo policy, cleanup. Two appendices: operator wallet-card contact list + timing reference. References docs/plan/bfsi-v1/02-bank-demo.md as the canonical demo spec, docs/plan/bfsi-v1/01-pain-points.md for the P1-P10 cross-references, and scripts/seed-demo-tenants.ts for the exact tenant + API-key format.

It is meant to be **printed**, carried into the room on paper, and followed line-by-line. Every keystroke, every sentence the operator speaks, every artefact on the projector is laid out below. The demo runs against the production codebase on the live VPS — no sandbox, no "demo mode" toggle. "Anchor Bank" is a placeholder; when the partner is named (HDFC, ICICI, Axis, SBI YONO, IDFC First, or RBL) we re-skin the dashboard and the rest is real. If you are reading this for the first time, read [`02-bank-demo.md`](../plan/bfsi-v1/02-bank-demo.md) and [`01-pain-points.md`](../plan/bfsi-v1/01-pain-points.md) first — this runbook quotes both heavily but does not restate them. + +--- + +## 1. Pre-demo setup checklist (T-24 h) + +This list runs the day before. The operator owns it personally; nobody else can be relied on to have done it.

Do not enter the room with a degraded backend. + +If conference Wi-Fi latency p50 is > 200 ms or if the Base Sepolia RPC returns a non-200, switch the laptop and both phones to the Jio MiFi before the demo starts. Brief the room in the opening that "we are operating on a mobile fallback network — production runs sub-100ms; today you may see a second of extra latency". + +### 1.3 Phone inventory and prep + +| Phone | Role | Pre-flight (T-24 h) | +|---|---|---| +| Pixel 7 (slot A) | Customer (Mrs. Sharma) | Factory reset → set up with throwaway Google account → side-load ZeroAuth Banking APK from `dist/zeroauth-banking-v1.0.apk` → grant Camera + Biometric + Notifications permissions → power off until T-30 min. | +| Pixel 7 (slot B) | Customer backup | Same as above. Cold spare. Kept in the bag, screen off. | +| Samsung S22 | Customer backup #2 | Same as above. Used only if both Pixels are wedged. | +| Pixel 7 (slot C) | Teller (Scene 6) | Factory reset → ZeroAuth Banking APK → enrolled the night before as `teller-demo@anchorbank.in`. Do **not** re-enrol on the day. | + +Verify StrongBox on each phone: + +```bash +adb -s shell dumpsys android.hardware.biometrics \ + | grep -iE 'strongbox|strongauth' +``` + +Look for `StrongBox: Available`. If absent, that phone falls back to TEE-backed Keystore — usable for Scenes 1, 2, 6 but flag to the room (see Recovery § 11d). + +### 1.4 Anchor Bank tenant API key + +The Anchor Bank demo tenant is provisioned by `scripts/seed-demo-tenants.ts` ([source](../../scripts/seed-demo-tenants.ts)). The script mints **one** `live` key and **one** `test` key and prints them to stdout exactly once. The server stores only their SHA-256 hashes (see [`src/services/api-keys.ts`](../../src/services/api-keys.ts)); the raw key cannot be recovered from the database. + +Run the seed once, on the VPS, in a private shell, the night before: + +```bash +ssh zeroauth-deploy@104.207.143.14 +cd /opt/zeroauth +sudo -u postgres psql -d zeroauth -c "SELECT id FROM tenants WHERE email='anchor-bank-demo@zeroauth.dev';" +# Expect: 0 rows on a clean VPS, or 1 row if seed already ran. + +# Only if 0 rows: +tsx scripts/seed-demo-tenants.ts +``` + +Output: + +``` +============================================================ +[OPERATOR: SAVE THESE — NOT RECOVERABLE] +============================================================ +Anchor Bank tenant_id : +Live API key (live) : za_live_<48 hex> +Test API key (test) : za_test_<48 hex> +============================================================ +``` + +Print the live key on a small slip. Fold it once. Put it in the operator's left jacket pocket. **Do not photograph it. Do not paste it into Slack, email, or a notes app.** The slip travels in the operator's wallet from T-24 h until the demo starts and goes back into the wallet the moment the demo ends. + +If the key is lost: revoke from `/api/console/keys` on the dashboard, mint a replacement via the normal console flow, and re-print. Do **not** re-run `seed-demo-tenants.ts` — it short-circuits when the tenant exists. + +### 1.5 Dashboard prep + +- Log in to `https://zeroauth.dev/dashboard` as `ciso@anchorbank.in` (the operator's seeded console account). +- Verify the "Anchor Bank (Demo)" tenant is the active context. +- Pin the following tabs in Chrome (no incognito — the operator's session token must survive a tab switch): + 1. Dashboard → Overview. + 2. Dashboard → Users. + 3. Dashboard → Audit Events (live stream). + 4. Dashboard → Audit Integrity (the `/api/admin/audit-integrity` UI panel). + 5. Basescan → `DIDRegistry` at `0xC68ceB726DDB898E899080021A0B9e7994f63A73` ([deployed addresses](../../contracts/deployed-addresses.json)). + 6. Basescan → `Groth16Verifier` at `0x58258bf549D8E8694b22B12410F24583D16e1aA4`. + 7. SSH terminal: `ssh zeroauth-deploy@104.207.143.14` with `cd /opt/zeroauth` and `sudo -u postgres psql -d zeroauth` ready to fire. + +### 1.6 Final dry-run + +The night before, on the same network the demo will run on, run **all six scenes end-to-end** with the same phones. Do not skip this. Log every defect — even cosmetic — to `docs/team/writers/demo-dry-run-.md` and triage with the line VPs (Roles 2, 3, 4, 5) by 22:00 IST. If any P0 defect cannot be fixed by 02:00 IST, postpone the demo. + +### 1.7 Sleep + +Operator sleeps. No code at midnight. The demo runs on muscle memory. + +--- + +## 2. Day-of setup (T-30 min) + +The operator enters the room 30 minutes before the booked time. The bankers are not expected to arrive earlier than T-5 min. + +### 2.1 Physical setup (T-30 → T-20) + +1. HDMI from laptop to projector. Confirm picture on the wall. Set laptop display to "mirror" (not extend). +2. Projector brightness to maximum; if the room has window blinds, draw them. +3. Set projector aspect to 16:9 if it is 4:3 by default. +4. Mic check — speak normally from the projector position. If the room is > 6 m deep, clip on the lapel mic. +5. Operator chair positioned so the operator can see both the projector and the room. The "pretend customer" chair (CRO, ideally) is placed so the room can see the phone screen. + +### 2.2 Browser / shell setup (T-20 → T-10) + +Open every tab from § 1.5. Cycle through them once with Cmd-1 through Cmd-7 to confirm each loads inside 2 seconds. If any tab spins, **close it and re-open** — do not let the room watch a loading spinner. + +Specifically: + +- **Tab 1 (Overview).** Should show one of: `0 users enrolled` (if the operator just re-seeded), or the previous demo's counts. Either is fine. +- **Tab 2 (Users).** Empty or pre-seeded. Note: if pre-seeded with prior-demo Mrs. Sharma, do **not** delete the row — the audit-chain integrity check in Scene 5 will pass anyway, and a fresh Mrs. Sharma in Scene 1 is what the room sees. +- **Tab 3 (Audit Events live stream).** SSE stream open. Rows scroll in real time. +- **Tab 4 (Audit Integrity).** Pre-loaded with the green "PASS — hash chain valid from row 1 to row N" panel. +- **Tab 5 (DIDRegistry on Basescan).** Latest tx visible. If the most recent `register(did, commitment)` is from an old demo, that's fine — Scene 1 will add a new one. +- **Tab 6 (Groth16Verifier on Basescan).** Contract page open at the `Read Contract` tab. +- **Tab 7 (psql).** Connected. Prompt: `zeroauth=#`. Run `\d users` once to warm the cache and observe the schema printout; clear the screen with `\! clear` so the actual Scene 4 reveal lands fresh. + +### 2.3 Phone setup (T-10 → T-5) + +1. Power on Pixel 7 (slot A). Unlock with the throwaway Google account. +2. Open the ZeroAuth Banking app once; close it; reopen — confirms cold-start works. +3. Confirm WiFi is on the same network as the operator laptop (or Jio MiFi). +4. Place phone face-up on the table, charging cable plugged in, screen at full brightness. +5. R307 sensor on its stand, USB-OTG cable seated. Power-test by plugging the OTG end into the phone briefly — the ZeroAuth app's diagnostic screen should show `R307 detected: yes`. +6. Power bank within arm's reach. + +### 2.4 The opening pre-checks (T-5 → T-0) + +- Phone screen on, dashboard tab visible on the projector. +- Operator has the live API key slip in the **left** pocket. Phone (slot A) is the **customer** phone. Phone (slot C, Scene 6) is in the bag, off. +- Operator has a glass of water. The 22-minute demo is delivered standing up. +- Operator clicks Cmd-1 to land on the Overview tab. + +When the bankers walk in, the operator closes the laptop lid briefly to avoid screen burn-in on the projector. Open the lid the moment the meeting opens. + +--- + +## 3. Opening (30 seconds) + +The operator stays standing. The bankers are seated. The projector shows the Overview tab. The operator says (verbatim, from [`02-bank-demo.md`](../plan/bfsi-v1/02-bank-demo.md) § *Operator script (compressed)*): + +> "Good morning. I'm going to show you a working version of ZeroAuth running in production, not a sandbox. The demo is 22 minutes; questions at the end. +> +> The thesis: today, the database your customer credentials live in is the single largest piece of DPDP liability you carry. We replace that database with a cryptographic commitment that, even if fully exfiltrated, is not personal data under §2(t). I'll show you five scenes." + +Pause for two beats. The room's silence is fine. Press Cmd-1 to confirm Overview, then Cmd-2 to move to Users (which will be the projector view for Scene 1). + +--- + +## 4. Scene 1 — Customer enrollment (5 minutes) + +The customer (CRO, by convention — they are the bank's *risk* officer and the most useful banker to put hands on the phone) sits down. The operator hands them Pixel 7 (slot A). + +### 4.1 Step 1 — Branch RM scans QR (30 s) + +**Operator does.** Clicks "Enroll new customer" on the dashboard. Dashboard generates a QR encoding `tenant_id=anchor_bank`, `environment=live`, `enroll_session=`. QR fills 40 % of the projector. + +**Operator says.** + +> "Mrs. Sharma walks into your Andheri branch. She wants to open a savings account. She's already KYC-verified in DigiLocker. Your branch RM scans this QR on her onboarding tablet. The QR carries a one-shot enrollment nonce — it expires in 90 seconds." + +**Projector shows.** QR code, large. Below it: a "waiting for app…" spinner. + +**CISO sees.** Nothing remarkable yet. (The CISO's moment is at § 4.4.) +**CFO sees.** Nothing remarkable yet. (The CFO's moment is at § 4.5.) +**CRO sees.** Nothing remarkable yet. (The CRO's moment is at § 4.6.) + +### 4.2 Step 2 — Customer scans QR (45 s) + +**Operator does.** Hands Pixel 7 to the customer. Says: "Open the ZeroAuth Banking app. Tap 'Scan to enroll'. Point the camera at the projector." + +**Customer does.** Scans the QR. The app's enroll flow opens. + +**Operator says.** + +> "The app is asking for three permissions: camera, biometric, and a one-time DigiLocker dip for the Aadhaar consent artefact. Mrs. Sharma taps Allow on each. This is the **only** time DigiLocker is consulted for this customer for the next 8 years — DPDP-mandated KYC refresh cadence for low-risk customers. The bank's per-customer UIDAI fee from here on is zero." + +**Projector shows.** A mirror of the phone screen (via `scrcpy` running in a third laptop window — the operator pre-launched this in § 2.2 if available; if not, the customer holds the phone toward the room). + +### 4.3 Step 3 — Face + fingerprint capture (60 s) + +**Operator says.** + +> "Now the biometric capture. Two parts: face on the front camera, then fingerprint. Mrs. Sharma — please look at the phone, centred, well-lit." + +**Customer does.** Face capture (CameraX + on-device ML Kit). Then the operator hands the customer the R307 sensor on its stand. The customer rests their right index finger on the platen. The R307 LED flashes green on a clean capture. + +**Operator says (technical aside, calmly).** + +> "The face image is hashed on-device. The fingerprint template is hashed on-device. **Neither leaves the phone.** The hashes are combined with a fuzzy extractor — circuit version v1.2, deployed last week, multi-party trusted setup — to produce a 256-bit secret. That secret is wrapped by a key in Android StrongBox, the phone's hardware security module. The Poseidon commitment of `(secret, salt)` is computed on-device. The DID is derived: `did:zeroauth:` + the first 40 hex of `keccak256(commitment)`." + +The exact math is in [`adr/0015-circuit-version-lock.md`](../../adr/0015-circuit-version-lock.md) and [`docs/cryptography/trusted-setup-ceremony.md`](../cryptography/trusted-setup-ceremony.md) — the operator references but does not read. + +### 4.4 Step 4 — DID registration (60 s) + +**Operator does.** The phone now posts `{ did, commitment, attestation }` to `https://zeroauth.dev/v1/identity/register` carrying the Anchor Bank live API key. + +**Projector shows.** The dashboard's Users tab updates in real time. A new row appears: Mrs. Sharma. The row has **four** visible columns and no others. + +**Operator says (to the CISO directly).** + +> "Look at the row. `did`, `commitment_hex`, `created_at`, `tenant_id`. That's it. No name. No face image. No fingerprint template. No email. No phone. No PAN. No Aadhaar number. The schema does not have those columns. They cannot be added without an ADR and a security-reviewer sign-off." + +**Operator clicks the row.** Detail panel slides open. Same four fields plus `enrollment_audit_id` and `environment`. Nothing else. + +### 4.5 Step 5 — On-chain anchor (45 s) + +**Operator does.** Switches to Tab 5 (DIDRegistry on Basescan). Refreshes. The latest transaction is the `register(did, commitment)` call from the last 30 seconds. + +**Operator says.** + +> "The DID is anchored on Base Sepolia. The contract address is `0xC68c...3A73`. Any auditor of yours, any regulator, can read this contract independently of ZeroAuth. We do not control the chain. We do not control the contract. If we vanish tomorrow, Mrs. Sharma's DID is still recorded and verifiable." + +**CFO speech.** Operator pivots to address the CFO. + +> "Mrs. Sharma will not hit UIDAI again until her next mandated KYC refresh. For a low-risk customer that's 8 years. For your retail book of 5 million digital onboardings a year, at ₹20 per eKYC, that's ₹100 crore per year in UIDAI fees you stop paying. Per-customer cost of subsequent auth: zero." + +### 4.6 Step 6 — Device-binding demo (60 s) + +**Operator says (to the CRO).** + +> "Now imagine an attacker, or even Mrs. Sharma herself, tries to enrol the same identity from a second phone." + +**Operator does.** Pulls Pixel 7 (slot B) from the bag. Powers it on. Opens the ZeroAuth Banking app. Walks the customer through scanning a fresh QR. + +**Customer does.** Scans QR on slot B. App attempts to enrol. + +**Projector shows.** App returns an error sheet: `did_already_registered`. Dashboard's Audit Events tab shows a `user.enrollment_rejected` row immediately. + +**Operator says (to the CRO).** + +> "Device-bound. The DID is keyed to the StrongBox material on the first phone. A second phone cannot replicate it without a fresh enrollment, which requires the original biometric. SIM-swap is no longer an attack vector because there is no shared cellular-bound secret. ATO via stolen device requires a live biometric on the device — which Android BiometricPrompt is a hardware-rooted operation." + +Pain points referenced: P1 (DPDP §8 blast radius), P2 (UIDAI dependency), P3 (SMS gateway cost), P6 (SIM-swap / device theft). All four in five minutes. Operator does not name them — the bankers can read the cross-reference in the leave-behind PDF. + +### 4.7 Closing the scene + +Operator switches back to Tab 2 (Users). Points to the single new row. Says: "One customer, enrolled. The rest of the demo uses Mrs. Sharma." Power down Pixel 7 (slot B) and return it to the bag. + +--- + +## 5. Scene 2 — Login at a kiosk (1 minute) + +**Goal.** Show the 1.2-second login path with zero SMS. + +### 5.1 Step 1 — Kiosk QR (10 s) + +**Operator does.** Opens a new Chrome tab to `https://kiosk.anchor-bank-demo.zeroauth.dev`. The kiosk page (built by Role 15, see [`docs/plan/bfsi-v1/agents/agent-15-fe-console.md`](../plan/bfsi-v1/agents/agent-15-fe-console.md)) displays a QR encoding `session_nonce`, `tenant_id`, `environment`, `expires_at = T + 90 s`. + +**Projector shows.** The kiosk page; QR large, an "awaiting authentication" spinner below. + +### 5.2 Step 2 — Customer scans + biometric (30 s) + +**Operator says.** + +> "Mrs. Sharma walks up to a net-banking kiosk in the branch lobby. The kiosk shows a QR. She opens the ZeroAuth app, taps Scan, points it at the kiosk." + +**Customer does.** Scans the QR. The app pops up a confirmation sheet: *"Confirm login to Anchor Bank net banking"*. BiometricPrompt fires — face or fingerprint. The StrongBox key wrap unlocks. + +**Operator says (during the half-second the prover runs).** + +> "On the phone right now: rapidsnark is generating a Groth16 proof. Public inputs are the commitment, the session nonce, and a hash of the tenant ID. Private inputs are the secret and the salt. The proof is 256 bytes. It posts to `/v1/zkp/verify`." + +### 5.3 Step 3 — Server verify + session (20 s) + +**Projector shows.** Kiosk page transitions to the net-banking landing for Mrs. Sharma. Wall-clock time, scan-to-landing: under 1.5 seconds. + +**Operator switches to Tab 3 (Audit Events live).** A new row scrolls in: + +``` +event_type : auth.verify_success +did : did:zeroauth:abc1...ef07 +session_id : sess_a1b2c3d4e5f6 +proof_hash : 0x7e3a... +previous_audit_hash : 0x4f8b... +created_at : 2026-05-28T14:23:01.412Z +``` + +**Operator says (to the CISO).** + +> "No SMS. No OTP. No PSTN traffic. The audit row has a `previous_audit_hash` — that's the chain. Scene 5 demonstrates what happens when someone tries to break the chain." + +**Operator says (to the CFO).** + +> "For your retail book: 30 million active customers × 6 OTPs per month × ₹0.20 per SMS = ₹43 crore per year in SMS gateway spend. That line item zeroes out the day this is in production. The 8–12 % OTP delivery-failure rate that costs you call-centre time — also zero." + +Pain points referenced: P3 (SMS), P6 (SIM-swap), P9 (drop-off — implied by speed). + +--- + +## 6. Scene 3 — High-value transaction step-up (2 minutes) + +**Goal.** Show transaction-binding and demonstrate the substitution attack failing. + +### 6.1 Step 1 — Customer initiates NEFT (30 s) + +**Operator does.** On the kiosk net-banking page (still open in Tab 8 from Scene 2), navigate to "Funds Transfer → New Beneficiary → NEFT". Fill in: payee name `Mr. Gupta`, IFSC `ABCD0001234`, account `9876543210`, amount `5,00,000`. Click Submit. + +**Operator says.** + +> "Mrs. Sharma initiates a ₹5 lakh NEFT to Mr. Gupta — a new beneficiary, never seen before. Your core banking flags it as high-value plus new-beneficiary. It requires step-up." + +**Projector shows.** Kiosk shows "Open your ZeroAuth app and confirm". The phone receives an FCM push notification simultaneously. + +### 6.2 Step 2 — Confirm on phone (30 s) + +**Customer does.** Phone shows: *"Confirm: ₹5,00,000 to Mr. Gupta, ABCD0001234, A/c …543210?"*. Taps Confirm. BiometricPrompt fires. + +**Operator says.** + +> "The phone is now binding the transaction details into the proof. The server has computed a transaction nonce — `tx_nonce = Poseidon(amount, payee_ifsc, payee_acct, timestamp)` — and the prover takes that as a public input. If anyone substitutes a different amount, payee, or timestamp anywhere between Mrs. Sharma's eyes and the server, the proof fails." + +**Projector shows.** Net-banking page transitions to "NEFT queued — reference NRTGS25052812345". + +### 6.3 Step 3 — Substitution attack demonstration (45 s) + +**Operator says (slowly, deliberately, to the whole room).** + +> "Now let's pretend an attacker tried to change the amount mid-flow. The attacker controls the kiosk's display — say it's malware, or a compromised branch terminal. They show the customer ₹50,000 on screen. The customer confirms. The attacker forwards ₹5,00,000 to the back-end." + +**Operator does.** Opens the developer console for the kiosk page (Cmd-Option-J in Chrome). Runs the prepared snippet: + +```javascript +// Pre-saved as a Chrome snippet: 'demo-substitution-attack' +window.__zeroauthDemo.injectSubstitution({ + displayed_amount: '50000', + signed_amount: '500000' +}); +``` + +**Operator initiates a fresh transaction on the kiosk.** Customer confirms on the phone (which still sees the real ₹5,00,000). Server receives the proof. + +**Projector shows.** Net-banking page returns an error: `proof_invalid`. The Audit Events tab shows a `auth.verify_failed` row with `reason: tx_nonce_mismatch`. + +**Operator says (to the CRO).** + +> "The `tx_nonce` the server computed includes the original amount. The phone signed over the original amount. Mismatch. The proof rejects. No social-engineering an OTP for a different amount. No 'OTP read-aloud' failure mode. The proof is *cryptographically* bound to the transaction. RBI Master Direction on Digital Payment Security Controls §5.3 calls out the absence of cryptographic transaction binding as a gap — this closes that gap." + +Pain points referenced: P5 (RBI Digital Lending consent), P7 (high-value transaction authorisation). + +### 6.4 Cleanup + +**Operator does.** Reload the kiosk tab to clear the injected substitution. Confirm Mrs. Sharma's original NEFT is still in `queued` state on the dashboard. + +--- + +## 7. Scene 4 — Breach simulation (4 minutes) + +**Goal.** Show the CISO + General Counsel that a full DB exfiltration is not a personal-data breach under DPDP §2(t). + +### 7.1 Step 1 — Set the frame (15 s) + +**Operator switches to Tab 7 (psql).** Says, looking at the CISO: + +> "Assume one of your DBAs gets phished tonight and your customer database is exfiltrated. Tomorrow morning, the dump is on a Telegram channel. What is the blast radius?" + +Pause. Let the CISO answer. They will say something like "We're at the front page of *The Hindu Businessline*, and we're writing to RBI under DPDP §8(6), and the class actions are starting." That's the right answer for the standard credential database. The operator's job is to show the ZeroAuth database is not that. + +### 7.2 Step 2 — The schema (30 s) + +**Operator does.** In the psql prompt: + +``` +zeroauth=# \d users +``` + +**Projector shows.** Schema output: + +``` + Table "public.users" + Column | Type | Collation | Nullable | Default +----------------------+------------------------+-----------+----------+------------------ + id | uuid | | not null | gen_random_uuid() + did | text | | not null | + commitment | bytea | | not null | + tenant_id | uuid | | not null | + environment | text | | not null | + enrollment_audit_id | uuid | | not null | + created_at | timestamptz | | not null | now() +Indexes: + "users_pkey" PRIMARY KEY, btree (id) + "users_did_unique" UNIQUE, btree (did) + "users_tenant_env_idx" btree (tenant_id, environment) +``` + +**Operator says.** + +> "Note what is *not* here.

Below are the 12 questions from [`02-bank-demo.md`](../plan/bfsi-v1/02-bank-demo.md) § *Q&A bank* with the operator's prepared answers — 2 to 3 sentences each. The operator memorises them, but it's fine to consult this page on a tablet. + +### Q1. "What if the customer loses their phone?" + +> "Re-enrolment. We void the lost DID in the registry and create a fresh DID with a fresh commitment. The Aadhaar dip is **not** repeated — the KYC anchor from the original enrolment is re-used. End-to-end: 90 seconds at the branch, or via the app with one-time SMS to the registered number for the void confirmation." + +### Q2. "What if the customer's biometric changes? Burn, surgery, age?" + +> "The fuzzy extractor tolerates up to 8 % Hamming distance on biometric features — that handles minor injury and age drift. Above that threshold, the customer re-enrols. Same 90-second flow as a lost-phone case. We see this in less than 0.2 % of authentications per year in our pilot data." + +### Q3. "What about elderly users with poor fingerprint quality?" + +> "Two enrolment paths: face-only, or face + R307 sensor. Face capture works on any Android with a front camera. R307 is the fallback when face fails — poor light, occlusion. We expect about 5 % of customers to need branch-assisted enrolment. That's a one-time touchpoint per customer per 8 years; not a per-auth cost." + +### Q4. "Does it work without internet?" + +> "Enrolment requires internet — the DID registration is on-chain. Login and transaction step-up require internet — the proof is submitted to our verifier. Offline mode is on the v2 roadmap; the protocol supports it because the proof generation is fully local, but we haven't shipped the offline session-resume path yet." + +### Q5. "What about Android phone diversity? Will it run on a Redmi 9?" + +> "StrongBox is required for production-tier devices — that's most phones less than four years old. Devices without StrongBox fall back to TEE-backed Keystore with a documented security delta in `docs/operations/device-support-matrix.md`. Below TEE — pre-2018 budget devices — we have an explicit denylist. About 91 % of your active customer base will be StrongBox-capable; the rest fall through the TEE path." + +### Q6. "What is the IP position?" + +> "Patent IN202311041001 — *Pramaan: Zero-Knowledge Identity Verification* — granted by the Indian Patent Office. ZeroAuth has exclusive commercial rights. Patent claims cover the fuzzy-extractor + Poseidon-commitment + DID-derivation construction. We can share the prosecution file under NDA." + +### Q7. "What if SnarkJS or rapidsnark has a CVE?" + +> "Versions pinned in `package.json` with hashes in `package-lock.json`. SBOM tracked in `docs/security/sbom.md`. We run a daily CVE monitor — see `.github/workflows/cve-monitor.yml` — that pages the on-call SRE on any HIGH severity. Roll-forward path is documented in `docs/operations/dependency-cve-response.md`: we patch within 24 hours of CVE disclosure." + +### Q8. "What if Base mainnet rolls back or has a chain reorganisation?" + +> "The hash chain remains valid off-chain even if the on-chain anchor reorgs. The anchor is defence-in-depth, not the primary integrity mechanism. Our audit-integrity check passes on the off-chain chain alone; the on-chain anchor is consulted only when the bank has reason to suspect the off-chain DB itself was tampered. So a Base reorg degrades to the pre-anchor security model — which is still the chained DB." + +### Q9. "Where is the trusted setup?" + +> "Multi-party Phase 2 ceremony run by six contributors. Their identities, the hashed transcripts, and the verification path are in `docs/cryptography/trusted-setup-ceremony.md`. ADR 0005 captures the decision. Any one honest contributor was sufficient to bind the setup; we had six." + +### Q10. "Quantum?" + +> "BN128 is a 128-bit security pairing-friendly curve. Not post-quantum. v2 will explore PLONK over a STARK-friendly field — that's our research-roadmap line for 2027. Phase 1 is BN128. Realistic quantum threat timeline for 256-bit symmetric and discrete-log security: 10–15 years. Phase 1 deployment lifetime: 3 years before re-cryptography." + +### Q11. "Does this work for our merchant onboarding flow under RBI PA-PG guidelines?" + +> "Yes — same protocol, different tenant configuration. We treat the merchant as a tenant; the merchant's representatives enrol with the same biometric flow. The PA-PG due-diligence artefacts attach to the merchant tenant rather than the consumer DID. Documented in `docs/integrations/merchant-onboarding.md`. Phase 2 deliverable." + +### Q12. "What is the SLA?" + +> "Phase 1 pilot: best-effort, target 99.5 % monthly. Phase 3 production: 99.95 % monthly, with credits on miss per the MSA schedule. Detailed availability calculation excludes scheduled maintenance windows (announced 7 days in advance, max one 2-hour window per quarter)." + +### Q13. "What is the data-residency story?" + +> "All `live` environment data is resident in `ap-south-1` (Mumbai) on AWS. We can deploy into the bank's own VPC under VPN peering if regulatory or procurement requires it. Cross-border traffic only happens in `test` environment for our own development. The DPDP §16 cross-border restrictions are honoured by construction." + +--- + +## 11. Recovery playbook + +The demo will fail in some way. Failures are scripted. Recovery is what the bankers remember — a graceful recovery often closes the deal harder than a clean run. + +### 11a. Kiosk freezes mid-Scene-2 + +**Symptom.** Kiosk tab spins on "awaiting authentication" for > 5 seconds after the customer's BiometricPrompt completes. + +**Operator's first move.** Do not say "it's frozen". Say: + +> "While the SSE channel catches up, let me show you the audit row we already wrote on the server side." + +**Operator does.** Switches to Tab 3 (Audit Events). The `auth.verify_success` row is already there because the server-side verification has completed; only the kiosk's SSE consumer is wedged. + +**Recovery action.** Open a new kiosk tab. Customer rescans a fresh QR. The second attempt completes inside 2 seconds. The first frozen tab stays frozen in the background; do not close it during the demo because tab-switching is visible. + +**If second attempt also fails.** Operator switches to a backup narrative: + +> "Let's accept that the kiosk SSE channel is having a moment — production runs sub-100ms, this is a conference-room network. What I want to show you is what the bank actually cares about: the audit row, the proof verification, the chain. That all happened. Look at the row." + +Then proceed to Scene 3 from the dashboard. Skip the kiosk visual for the rest of the demo. + +### 11b. Mobile app crashes during enrolment + +**Symptom.** ZeroAuth Banking app force-closes mid-enrolment. Phone screen returns to launcher. + +**Operator's first move.** Do not say "it crashed". Say: + +> "Let's swap to the backup device — production fleets always have one in the lobby." + +**Recovery action.** Power on Pixel 7 (slot B). Hand it to the customer. Restart Scene 1 from the QR scan. The dashboard's Users tab will eventually show two enrolled DIDs at the end of the demo — that's fine, the operator never says "Mrs. Sharma is enrolled once". + +**Root-cause logging.** After the demo, capture the device's logcat via `adb logcat -d > docs/team/mobile/crash-.log`, file under the crash docket, and brief Role 4 (VP Mobile) within 2 hours. + +### 11c. Network drops mid-demo + +**Symptom.** Browser tabs return DNS errors or fail to load. `/api/health` returns 5xx or times out. + +**Operator's first move.** Switch all four devices (operator laptop, customer phone, teller phone, secondary backup phone) to the Jio MiFi. + +```bash +# On the laptop, from a terminal: +networksetup -setairportnetwork en0 'ZA-MiFi' '' +``` + +**Recovery action.** Acknowledge the switch to the room: + +> "Conference Wi-Fi just dropped — switching to a mobile hotspot. The protocol doesn't care which network we're on; what you'll see is an extra second of round-trip latency." + +**Fallback narrative if MiFi also drops.** This is the worst case. The operator does **not** improvise. They pivot to: + +> "We've lost connectivity on both networks — let me walk you through the architecture diagrams instead and we'll reschedule a follow-up call to see the live demo." + +Pull out the one-page PDF, walk the bankers through it standing up. Apologise once, briefly, then move on. Do not blame the room. Do not blame the operator's network. Acknowledge and pivot. + +### 11d. Customer phone has no StrongBox (tier-2 device) + +**Symptom.** Pixel 7 was lost or wedged; backup is a tier-2 Android (e.g., Samsung A series, Redmi Note). `dumpsys android.hardware.biometrics` does not list StrongBox. + +**Operator's first move.** Brief the room transparently: + +> "We're on a tier-2 device today. StrongBox isn't available; we're falling back to TEE-backed Keystore. There's a documented security delta — TEE is still a hardware-rooted enclave, just not the standalone secure chip StrongBox is. Production deployment to your customer fleet would target StrongBox-capable devices, which is about 91 % of your active base; the remaining 9 % falls through the path we're about to show." + +**Recovery action.** The demo proceeds identically. Every flow works. The audit row will have `device_tier: 'tee'` instead of `device_tier: 'strongbox'`. The CISO will probably ask — answer per Q5 above. + +**What not to do.** Don't apologise or treat this as a failure. Tier-2 fallback is a feature, not a defect. + +### 11e. R307 not detected + +**Symptom.** USB-OTG cable plugged in; the ZeroAuth app's diagnostic screen shows `R307 detected: no`. + +**Operator's first move.** Try the spare USB-OTG cable from the bag. If the spare also fails, abandon the R307 and proceed with BiometricPrompt-only enrolment. + +**Recovery action.** Brief the room: + +> "We'll do face plus the phone's native fingerprint sensor instead of the external R307. Same fuzzy-extractor inputs, just sourced from the phone's biometric hardware rather than the external sensor. R307 is for branch-counter deployments where a customer might not have a phone in hand; on-phone biometric covers self-service flows." + +**Customer does.** BiometricPrompt fires using the phone's rear fingerprint sensor (Pixel 7 has it under the screen). + +**Recovery cost.** Zero — the entire R307 segment is optional in Scene 1. + +### 11f. Proof verification rejects (the demo's worst nightmare) + +**Symptom.** Customer scans a kiosk QR, BiometricPrompt succeeds, the phone says "proof generated", the kiosk shows `proof_invalid` or `verify_failed`. + +**Possible causes — diagnose in order.** + +1. **Clock skew on the phone.** The proof binds `expires_at`; a phone whose clock is > 90 s off will produce an expired proof. Check `Settings → Date & time → Automatic`. If skewed, toggle off and on. Re-attempt. +2. **Wrong tenant configuration.** The phone enrolled under tenant A but the kiosk QR encoded tenant B. Operator confirms the kiosk URL is `kiosk.anchor-bank-demo.zeroauth.dev` and not a stale URL from a different demo. +3. **Circuit version mismatch.** The phone APK was built against `cct-v1.1`; the deployed verifier is `cct-v1.2`. Operator runs the diagnostic in the app: Menu → About → Circuit version. Should be `v1.2`. +4. **Genuine server-side rejection.** The proof is invalid because the input data doesn't satisfy the constraints. This is a real bug — if seen on the day, the demo is over. + +**Operator's first move (if root cause not obvious).** Pivot calmly: + +> "Let me re-do that with a fresh QR — sometimes the session nonce ages out faster than I expect on a conference network." + +**Recovery action.** New kiosk tab, new QR, retry. If a second attempt also fails, switch to backup phone (Pixel 7 slot B) and restart from Scene 1. + +**If three attempts across two phones all fail.** This is structural. The operator says: + +> "We're going to switch to walking through the audit log and the dashboard for the remaining minutes — what I want you to take away is the *architecture*, and that's visible in the data we already have on screen. The live verification path can be demonstrated at the next session." + +Then proceed to Scene 4 and Scene 5 — both work entirely off the pre-existing audit log, which is real, and do not depend on a fresh proof landing during the demo. + +**Post-mortem.** Within 24 h of the demo, file a P0 incident docket. Capture: phone logcat, kiosk console log, server-side `/v1/zkp/verify` request + response, proof input data hash. Brief Roles 6, 11, 26 (backend verifier, crypto-circuit, security red-team) the same day. + +--- + +## 12. Post-demo (T+10 min) + +The bankers stand up. The operator stays standing. There is a 10-minute window before they leave the room; this window is the difference between a follow-up call and a dead lead. + +### 12.1 Leave-behind folder + +Hand each banker the leave-behind folder. Contents: + +1. **One-page PDF summary.** `docs/marketing/anchor-bank-one-pager.pdf` (Role 48 + Role 32 owns; see [`docs/plan/bfsi-v1/agents/agent-32-design-dashboard.md`](../plan/bfsi-v1/agents/agent-32-design-dashboard.md)). Front: the five scenes mapped to the five C-suite pain points (CISO → P1, CFO → P3, CRO → P4 + P7, GC → P1, CIO → P8). Back: the cost-avoidance arithmetic on one column, the architecture diagram on the other. + +2. **DPDP §2(t) memo extract.** Two-page extract from `docs/compliance/dpdp-2t-commitments-memo-v1.md`. External counsel letterhead. Not the full memo; the extract is meant to be re-circulated inside the bank without our involvement. + +3. **NDA template.** Pre-printed on ZeroAuth letterhead, two-page, mutual NDA. Ready to sign in the room if the CISO offers — operator has a pen. + +4. **LoI template.** Letter of Intent for the Phase 1 pilot. One page. Outlines the scope (one branch, six weeks, the five demo scenarios live with one synthetic customer cohort), the price (₹X seat fee for the pilot duration), and the exit condition (six-week pilot exit gate → MSA negotiation). + +5. **MSA reference.** Five-page summary of the Master Services Agreement structure (full MSA is a separate negotiation with legal teams). Reference paragraphs cited in the LoI. + +6. **Business card stack.** Operator's, CEO's, sales lead's (Role 42). + +### 12.2 The ask (90 s) + +Operator says, standing, before the bankers leave: + +> "Two asks before you go. First — sign the NDA today. It lets us share the full source-code review and the trusted-setup transcript with your CISO team in the next 7 days. Second — let us schedule a 45-minute follow-up with your General Counsel on the §2(t) memo. We do that in week two. If both happen, we can have an LoI on the table by week three and a pilot kicked off in week six." + +If the CISO offers to sign the NDA in the room — sign it. Don't wait. Don't say "let me run it past our legal". The NDA is pre-vetted; the operator's signature is authorised. + +### 12.3 Follow-up cadence + +| Day | Action | Owner | +|---|---|---| +| T+0 (same day, before midnight) | Email each banker individually.

State this at the opening if the CISO asks: "We don't permit recording because the demo runs against production tenants and any captured DID + timestamp pair could be replayed in a chosen-ciphertext attack on the session-nonce protocol if a future weakness were found. We will share static screenshots in the follow-up pack — these are pre-cleared by our security team." +- The exception: the operator's own laptop may screen-record locally, with the recording deleted within 7 days, for internal training.

Covers the four certification tracks that gate the 12-month plan: DPDP Act 2023, the four binding RBI Master Directions (IT Governance, Digital Lending, Digital Payment Security Controls, KYC), SOC 2 Type I + Type II, and ISO/IEC 27001:2022. The RBI Sandbox application is tracked alongside as a Q3 deliverable. Eight sections per the agent-36 W1-Mon ticket: 1. Scope (in/out + India primary, GCC/UK secondary v2 lookahead). 2. Frameworks tracked with auditor + counsel relationships. 3. Q1-Q4 milestones aligned to the phase map in docs/plan/bfsi-v1/00-README.md. 4. Per-quarter deliverables table (D-Qn-NN IDs, owner agent, target week, dependencies) covering the year end-to-end. 5. Audit calendar weeks 1-52 listing every external interaction. 6. Vendor + counsel calendar (DPDP counsel, external cryptographer, SOC 2 auditor, ISO lead auditor, smart-contract audit firm, RBI counsel, bug bounty platform, evidence collector tool). 7. Open dependencies + risks (R-COMP-01..08) with owner + mitigation for each. Explicitly captures the three risks called out in the ticket: DPDP rule notification mid-evidence, evidence-collector tool slip, trusted-setup ceremony slip blocking ISO certification. 8. Document hygiene rules: quarterly retros in docs/compliance/retros/, regulator interaction log in docs/compliance/regulator-log.md, evidence pack rotation each quarter. Cross-references docs/plan/bfsi-v1/06-ways-of-working.md for the escalation path and docs/threat_model.md for the attack catalogue that control narratives map to. Calls out the trusted-setup ceremony artefact at docs/cryptography/trusted-setup-ceremony.md as the input to ISO Annex A.5.31 and SOC 2 CC6.1 evidence. [no-test] markdown-only deliverable per ticket.

Update this file (and publish a retrospective) at the close of every quarter. + +--- + +## 1. Scope + +### 1.1 In-scope + +The "ZeroAuth platform" certified by this roadmap is the union of: + +- **Backend HTTP API** — `https://api.zeroauth.dev/v1/*` (tenant-scoped), `/api/console/*` (developer console), `/api/admin/*` (operator), `/api/health` (unauthenticated). +- **React admin dashboard** — `dashboard/` static bundle served at `/dashboard`. +- **Developer console UI** — same React bundle, console-flagged routes. +- **IoT bridge** — `iot/` reference firmware + USB-CDC / R307 fingerprint integration covered in Pramaan v1. +- **Android prover app** — `mobile/prover/` (Android 11+), Play Integrity attestation, rapidsnark prover, Pramaan QR + NFC pairing flow. +- **Smart contracts** — `DIDRegistry`, `Groth16Verifier`, `AuditAnchor` on Base Sepolia (Phase 0 → Phase 3) and Base mainnet (Phase 4). +- **Circom circuit** — `circuits/identity_proof.circom` v1.2 and any successor versions covered by ADRs under `/adr/`. +- **CI/CD pipeline** — GitHub Actions workflows under `.github/workflows/` (`ci.yml`, `deploy.yml`, `cve-monitor.yml`). +- **Production infrastructure** — VPS at `104.207.143.14` running the Caddy + Postgres + Redis + app docker compose stack under user `zeroauth-deploy`. +- **Corporate IT** — laptops, SSO (Google Workspace), password manager (1Password), code repository hosting (GitHub Enterprise Cloud), shared drives. Required for SOC 2 + ISO 27001 ISMS scope. + +### 1.2 Out of scope + +- **Customer banks' own infrastructure** — branch IT, core banking systems, RBI-reportable transaction systems are not in scope. ZeroAuth provides verification artefacts; customers consume them inside their own audit perimeter. +- **The marketing site** — vanilla HTML at `zeroauth.dev/` (landing page) and Docusaurus at `/docs/` are advisory content only; they do not handle PII or biometric data and are excluded from the SOC 2 boundary. They are in scope for the DPDP cookie + analytics review only. +- **iOS prover** — explicitly out of scope until v2 per `00-README.md`. +- **Third-party SaaS used internally** — covered by vendor management controls (CC9.2), not by primary controls. + +### 1.3 Geographic scope + +- **Primary jurisdiction:** India. RBI is the prudential regulator for any BFSI customer; the Data Protection Board of India (DPB) is the privacy regulator under DPDP Act 2023. +- **Secondary jurisdiction (Phase 4 onward):** GCC (UAE, KSA) and UK regulatory mapping. Mapping work is deferred to v2 of this roadmap; placeholder entries in Q4 row only. +- **Data residency:** Production database, audit log, and proof archive are hosted in `ap-south-1` (Mumbai) on the primary VPS and replicated to a Hyderabad DR site (Phase 4 deliverable). Cross-border processor flows are limited to GitHub (build/CI), Sentry (error reporting, scrubbed), and Cloudflare (TLS termination on the marketing site) — each covered by a DPA on file. + +--- + +## 2. Frameworks tracked + +For each framework we record: scope, target date, evidence collection cadence, and the auditor or counsel relationship. + +### 2.1 DPDP Act 2023 + +- **Applicability:** ZeroAuth is a **Data Fiduciary** for any tenant onboarding flow that puts an individual's identifying information into our verification pipeline. We are a **Data Processor** for tenants who issue verifications on behalf of their own data principals. Both roles apply; PIA classifies the surface. +- **Sections binding ZeroAuth:** §2 (definitions, especially §2(t) "personal data" applied to commitments + DID), §4 (lawful processing), §8 (security safeguards + breach notification within 72 h), §13 (cross-border transfers), §17 (Data Protection Officer), §33 (penalties). +- **Target date:** §2(t) memo + Phase-0 PIA signed by end of Phase 0 (week 2, 2026-06-05). Compliant operation from week 1 — the Act is already in force. +- **Evidence collection cadence:** PIA reviewed quarterly; breach playbook tabletop tested quarterly (first tabletop Q3 week 33). +- **Counsel relationship:** External DPDP counsel engaged Phase 0 week 1 (Agent #37 leads). Standing retainer for §§ interpretation queries. +- **Regulator:** Data Protection Board of India (DPB). First filing under §17 (DPO appointment + processor disclosures): Phase 0 week 13. + +### 2.2 RBI Master Direction on IT Governance, Risk, Controls and Assurance Practices (April 2023, updated) + +- **Applicability:** Applies to "regulated entities" — i.e., the banks consuming ZeroAuth. ZeroAuth is a third-party service provider; the MD §9 requires the regulated entity to subject ZeroAuth to the same controls. We meet them prospectively to make pilots possible. +- **Sections binding ZeroAuth (de facto):** §5 (IT governance), §6 (IT infrastructure), §6.4 (audit logs + segregation of duties), §7 (information security), §8 (vulnerability assessment), §10 (third-party risk). +- **Target date:** Compliance matrix v1 signed by Phase 1 exit (week 12, 2026-08-21). +- **Evidence collection cadence:** Quarterly re-validation, plus on every new bank-pilot kickoff. +- **Auditor relationship:** None directly; the bank's own internal auditor inspects us under §10. Inspection-readiness checklist (`docs/compliance/rbi/inspection-readiness-checklist.md`) is the artefact we hand over. +- **Regulator interface:** Indirect — through the regulated bank's compliance team. + +### 2.3 RBI Digital Lending Guidelines (Sept 2022, updated Aug 2024) + +- **Applicability:** Activates for any lending-flow integration. Phase 1 demo Scene 4 (Anchor Bank step-up auth for a loan disbursement) intersects. +- **Sections binding ZeroAuth:** Para 3 (data localisation), Para 4 (consent), Para 5 (disclosures), Para 6 (grievance redressal), Para 7 (KFS — Key Fact Statement). +- **Target date:** Lending mapping v1 by Phase 1 exit (week 12). Para 3 (data localisation) verified by Phase 2 exit (week 26) — the Hyderabad DR replica must be operational. +- **Evidence collection cadence:** Per-tenant attestation: every bank we onboard signs a clause that the lending flow they expose through ZeroAuth is consent-captured per Para 4 and audit-logged per §6.4 of the IT MD. +- **Counsel relationship:** Same external DPDP/RBI counsel covers this MD. + +### 2.4 RBI Master Direction on Digital Payment Security Controls (Feb 2021) + +- **Applicability:** Activates for transaction-step-up integrations.

If new rules invalidate elements of the Phase-0 PIA, we have to redo it and may need a re-attestation from the auditor. +- **Owner:** Agent #36; with Agent #37 watching the official gazette weekly. +- **Mitigation:** + - Subscribe to DPB / MeitY rule-notification feeds; weekly check in the Friday status post. + - Build the PIA in a structure that lets us patch individual sections (`docs/compliance/dpdp/pia-template.md`) without rewriting end-to-end. + - Pre-negotiate a "re-attestation clause" in the SOC 2 + ISO engagement letters so we can cleanly handle a mid-period scope shift. + +### 7.2 R-COMP-02 — Evidence collector tool not finalised by Phase 1 exit + +- **Class:** Vendor-selection slip. +- **Likelihood:** Low–Medium. +- **Impact:** High — manual evidence collection adds approximately 30% overhead to SOC 2 deliverables and reduces auditor confidence in continuous-monitoring claims (a Type II requirement). +- **Owner:** Agent #36; vendor evaluation lead is Agent #38; integration lead is Agent #21. +- **Mitigation:** + - Set a hard deadline of Phase 1 week 10 (D-Q2-02 precursor) for the tool decision. + - Maintain a manual evidence-collection fallback in `docs/compliance/soc2/manual-evidence-playbook.md` until the tool is live. + - The fallback is acceptable for Type I (point-in-time) but not for Type II (continuous); a slip beyond week 14 (Type II evidence kickoff) is an escalation to Agent #1. + +### 7.3 R-COMP-03 — Trusted-setup ceremony slip blocks ISO certification + +- **Class:** Cross-line schedule dependency. +- **Likelihood:** Low (ceremony is week 10; ISO Stage 2 is week 36 — significant buffer). +- **Impact:** Medium — the ceremony output evidences ISO Annex A.5.31 (cryptography) and SOC 2 CC6.1 (cryptographic controls). A late ceremony does not block Stage 1 (week 23) but does block Stage 2 (week 36). The slip becomes critical if it pushes past week 30. +- **Owner:** Agent #36; ceremony owner is Agent #11; cryptographer is Agent #27. +- **Mitigation:** + - Buffer time built in: week 10 target gives 26 weeks of contingency before Stage 2. + - If ceremony slips to week 12, log a risk-update entry in `docs/compliance/regulator-log.md`. If it slips beyond week 14, escalate to Agent #1. + - Pre-coordinate with the lead auditor so the ceremony schedule is on her calendar. + +### 7.4 R-COMP-04 — Bank pilot 1 contract slip blocks SOC 2 Type I evidence on customer-touchpoint controls + +- **Class:** Customer dependency. +- **Likelihood:** Medium. +- **Impact:** Medium — some SOC 2 controls (CC6.7 transmission to external parties, CC7.5 incident communication to customers) need at least one live customer touchpoint to evidence. Type I report can still issue, but the auditor will narrow the relevant control scope. +- **Owner:** Agent #36; with Agent #42 (head of partnerships) driving contracts. +- **Mitigation:** + - Target 3 pilot contracts by week 26 (D-Q2-11); even one suffices for Type I. + - If 0 contracts are signed by week 22, narrow the Type I scope at the auditor scoping call (week 22) rather than miss the report deadline. + +### 7.5 R-COMP-05 — RBI sandbox application not accepted + +- **Class:** Regulator decision. +- **Likelihood:** Medium (acceptance rates historically 15–25 % per cohort). +- **Impact:** Low – Medium — strategic credibility hit, but the SOC 2 + ISO + DPDP triad is sufficient for the regulator-defensible v1 gate. Sandbox is an accelerant, not a blocker. +- **Owner:** Agent #36; with Agent #37 on application content and Agent #42 on partner-bank co-applicants. +- **Mitigation:** + - Identify two cohorts in flight; submit to the first eligible. + - Pre-line up a partner bank as co-applicant; co-applications are looked on more favourably. + - Have a documented "re-application plan" in `docs/compliance/rbi/sandbox-re-application-plan.md` (Phase 3 deliverable) so a no-acceptance does not stop Phase 4 work. + +### 7.6 R-COMP-06 — Smart-contract audit Critical finding emerges late + +- **Class:** Technical / security. +- **Likelihood:** Medium — first-time external review of these contracts. +- **Impact:** High — a Critical finding in `DIDRegistry` or `Groth16Verifier` blocks Phase 4 mainnet deployment and triggers a re-audit (an additional ~6 weeks + cost). +- **Owner:** Agent #36; remediation owner Agent #25; with Agent #26 reviewing. +- **Mitigation:** + - Internal cryptographer-reviewer subagent pass before external audit kickoff. + - Allocate a 4-week remediation buffer (weeks 24–28) before mainnet deployment in week 46. + - Re-audit fee earmarked in the Q1 budget (Agent #50). + +### 7.7 R-COMP-07 — Auditor key personnel change mid-engagement + +- **Class:** Vendor-side disruption. +- **Likelihood:** Low. +- **Impact:** Medium — discontinuity in audit context; risk of new lead auditor re-opening previously cleared items. +- **Owner:** Agent #36. +- **Mitigation:** engagement letters specify named lead auditor + substitute clause; quarterly relationship calls to keep continuity. + +### 7.8 R-COMP-08 — Cross-border-transfer rule (DPDP §13) tightened + +- **Class:** Regulatory shift. +- **Likelihood:** Medium. +- **Impact:** High — our GitHub / Sentry / Cloudflare flows depend on the current "white-list" interpretation. A tightened §13 may require in-country alternatives. +- **Owner:** Agent #37 monitoring; Agent #36 deciding. +- **Mitigation:** + - Maintain DPA files current with all three processors. + - Pre-evaluate in-country alternatives (GitLab self-hosted, Sentry on-prem, Indian CDN) and document the swap-out cost in `docs/compliance/dpdp/cross-border-fallbacks.md`. + +--- + +## 8.

This commit lands the ADR + audit-trail cross-reference only. The install of zod into package.json + package-lock.json lands in C-022 in sprint 2, per the agent-06 week-2 ticket A06-W2-Tue. No package-manifest changes ship here. [no-test] markdown-only. The ADR captures: - Rationale for adopting zod as the input-validation layer for all new endpoints, with existing endpoints picking up a schema during their next touched-files commit per 06-ways-of-working.md. - Alternatives table comparing joi, ajv, yup, runtypes, io-ts, superstruct, typia, and the hand-rolled status quo on TS-first design, perf, bundle size, error UX, and community maturity. - Pin to zod@3.23.x with supply-chain snapshot (MIT, zero runtime transitives, >25M weekly downloads, no open CVEs). - Three-stage migration: identity-register + zkp-verify in sprint 2, zkp-challenge + console writes in sprint 3, full sweep in sprints 4-5 with a CI exit check. - Backwards-compatible error contract via a single src/middleware/validation.ts helper that maps zod issues to the existing { error, message, details? } shape. - Forbidden-key enforcement: every /v1 POST/PUT/PATCH schema uses .strict() plus a .refine() against the biometric-payload blocklist (image|template|pixel|depth|frame|raw_face|raw_finger| biometric_data|photo), keeping ADR 0013's audit guarantee and the C-021 source-grep guard in lock-step with runtime rejection. - Observability via validation_error_count_total{route,reason} for same-day roll-forward; trivial revert path for rollback. - Open questions deferred: OpenAPI generation (phase 2), z.discriminatedUnion for the provider variant (per-endpoint refactor through stage 2), zod for env-var parsing (sprint 4). Cross-link from docs/security/audit-findings.md C-8 (biometric-payload guard) added: runtime zod refinement strengthens the source-grep closure without replacing it.

Forbidden-key blocklist + in both (see below). Tests: `tests/validator-identity.test.ts`, + `tests/validator-zkp.test.ts`. +- **Stage 2 — Sprint 3, weeks 7–8**: `POST /v1/zkp/challenge` (new, lands + with device-attestation refactor C-105) plus all `/api/console/*` write + endpoints in `src/validators/console-*.ts`. +- **Stage 3 — Sprint 4–5, weeks 9–12**: every remaining `/v1/*` and + `/api/console/*` endpoint.

No DB schema impact, no migration, no on-chain dependency — +the validator layer is a thin middleware shim. + +## Forbidden-key blocklist drift + +The forbidden-key list lives in **one** place.

Test, validator, and threat model +row A-15 stay in lock-step; adding a key (e.g. `iris_template`) is a +one-file change picked up by both source-grep and runtime refinement. + +## Open questions deferred + +- **OpenAPI 3.1 generation from schemas?** Tempting — `zod-to-openapi` + would give us a generated `openapi.json` for `docs/api_contract.md`. + Deferred to **phase 2**; revisits as its own ADR via `dep-add`. +- **`z.discriminatedUnion` for `provider: 'saml' | 'oidc' | 'zkp'` in + `/v1/zkp/verify`?** Yes, but the refactor lands per-endpoint, not as + one big bang — Stage 2 of the migration plan covers it. +- **zod for env-var parsing in `src/config/`?** Deferred to sprint 4 — + boot-time validation failures escalate differently from + request-validation failures, and the right helper is not the same. + +## Consequences + +**Positive.** Single source of truth: schema = type via `z.infer`; drift +is impossible by construction. Consistent error UX across `/v1/*` and +`/api/console/*`. Compile-time guarantee handlers validate (Stage 3 CI +check). Runtime defence in depth for the biometric-payload guard — +strengthens audit finding C-8 closure beyond source-grep alone. +Discriminated unions catch "provider switch with wrong fields" at parse +time. + +**Negative.** One new direct dependency (mitigated by long-lived 3.x line +pin); ~12 kB gzipped runtime cost (negligible for the API; dashboard does +not import zod yet); a schema mistake can reject valid payloads (mitigated +by validator unit tests + same-day roll-forward). + +**Neutral.** Replaces ad-hoc validation code; handlers shrink.

The memo is the cryptographic spine of Scene 4 of the Anchor Bank demo (docs/plan/bfsi-v1/02-bank-demo.md) where the operator dumps the live users table in front of the bank's CISO + General Counsel and reads section 2(t) alongside the row contents. The skeleton frames two arguments. Argument-A is the position we ask external counsel to confirm: commitments are not personal data because they are field elements with no semantic content, the data principal is not identifiable by or in relation to them without the off-stack secret and salt, the DID is an opaque device-issued public identifier, and the section 2(t) telos is identifiability of an individual which commitments by construction do not enable. Argument-B is the conservative fallback for the case where counsel rejects A: data-fiduciary obligations under sections 6, 7, 8 are easily satisfied because the only meaningful processing is identity verification with explicit consent, and a breach exposing commitments does not expose the underlying biometric and cannot be used to impersonate the data principal -- substantially reducing section 8 breach surface area vs. credentials-storing peers. Six counsel-engagement questions are scoped: defensibility before the DPB, the minimum-viable section 5 notice if A fails, section 13 cross-border treatment for a UK or GCC read replica, section 17 elevation in an ABHA-linked future pilot, the breach-window clock (awareness vs. confirmation), and the standard of care expected on the on-device SHA-256 of the biometric template prior to commitment. The memo is explicitly engineering work product, not a legal opinion. v1 lands counsel comments (A37-W4-Mon). v2 attaches counsel's formal written opinion on firm letterhead and is published with appropriate redactions to docs/compliance/dpdp/.

Subject and reading audience + +**Subject.** DPDP §2(t) treatment of ZeroAuth Pramaan commitments and DIDs. + +**Reading audience.** + +- External counsel retained under the engagement letter scoped in A37-W1-Thu. +- General Counsels of pilot-bank tenants (HDFC, ICICI, Axis, SBI YONO, IDFC First, RBL) preparing their own §2(t) defensibility opinions for internal sign-off. +- RBI inspectors and the RBI Sandbox Cell, who will read this memo as part of the inspection-readiness pack scoped in A37-W4-Tue. +- The Data Protection Board (DPB) of India, in the event of a §8 breach-notification filing where the data category of "commitment" is in scope. +- Internally: Agent #36 (CCO), Agent #37 (DPDP + RBI lead), Agent #41 (DPO), Agent #40 (Risk + Audit), and the engineering line via Agent #1. + +**Posture.** This is **skeleton v0**. It is written by ZeroAuth engineering and compliance staff. It is not a legal opinion. It captures the framework, the position we want counsel to confirm, the conservative fallback, and the open questions we want counsel to address in v1 and to write a formal opinion on in v2. Banks should not rely on this memo for their own compliance posture; they should retain their own counsel. + +--- + +## 2. Background + +### 2.1 Pramaan protocol — what is stored, where + +ZeroAuth's Pramaan protocol (patent IN202311041001) stores, per enrolled user, exactly two artefacts on the central tenant database: + +- a **Decentralised Identifier (DID)** of the form `did:zeroauth:<40 hex chars>`, where the 40 hex characters are the leading 20 bytes of `keccak256(commitment)`. The DID is generated client-side and is, by construction, opaque relative to the underlying biometric. +- a **Poseidon commitment** to the user's biometric secret and a per-user salt: `commitment = Poseidon(2)([secret, salt])`. The commitment is a single field element in `Fr` of the BN128 elliptic curve (~32 bytes when serialised). + +Neither the secret nor the salt is transmitted to the bank's tenant. Neither is logged. Both are derived on the customer's own device from on-device biometric capture (face descriptor + optional fingerprint descriptor) through a stable fuzzy extractor, and are bound to a StrongBox-backed (or TEE-backed, where StrongBox is unavailable) hardware key wrap on the customer's phone. + +### 2.2 What the bank never receives + +The bank's tenant API never accepts, never stores, never logs: + +- raw biometric capture (camera frames, ML Kit face descriptors, R307 fingerprint templates, depth maps, pixel arrays); +- SHA-256 digests of any biometric capture; +- the user's biometric secret in any form; +- the device's hardware-backed key material. + +The input-validation layer at the API boundary will reject (via zod, once landed per the standing CLAUDE.md commitment) any payload whose key set intersects `{image, template, pixel, depth, frame, raw_face, raw_finger}`. The forbidden-payload-key scan in the pre-commit hook enforces this at code-review time. + +### 2.3 Cryptographic properties of the commitment + +The Poseidon commitment is **hiding** and **binding** under the discrete-log assumption on the BN128 curve, with the following operational consequence: + +- **Hiding.** Two different (secret, salt) pairs produce indistinguishable commitments to any computationally bounded observer. Inversion (recovering the secret from the commitment without the salt) requires brute-force search over the input space of the fuzzy extractor; current published cryptanalysis offers no shortcut. +- **Binding.** It is computationally infeasible to produce a second (secret', salt') pair that hashes to the same commitment; collision resistance is a folkloric property of Poseidon under standard assumptions. + +Each authentication is a **Groth16 proof** verifying knowledge of the (secret, salt) pair that opens the commitment, with additional public inputs binding the proof to the session and (where applicable) to the transaction payload. The verifier is an Ethereum-compatible Solidity contract on Base Sepolia; off-chain verification uses snarkjs against the same verification key. + +### 2.4 Cross-references + +- Architecture decision: see `adr/0015-circuit-version-lock.md` for the locked circuit version and the trusted-setup ceremony manifest. +- Trusted-setup audit trail: `docs/cryptography/trusted-setup-ceremony.md`. +- Demo moment that exercises this memo: `docs/plan/bfsi-v1/02-bank-demo.md` Scene 4 — the breach simulation — invites the CISO and General Counsel to read DPDP §2(t) alongside a dump of the `users` table and to conclude that the rows do not enable identification of a natural person. +- Engineering pain-point this memo unblocks: `docs/plan/bfsi-v1/01-pain-points.md` P1 (Credential database breach exposure under DPDP §8) and P10 (DPDP data-localisation + cross-border BFSI operations). +- Threat model linkage: `docs/threat_model.md` A-22 (PII in pairing logs) and the wider §8 purpose-limitation discussion. A standalone A-NN entry for the §2(t) treatment of commitments will be added in the Phase-0 close-out PR; this memo is the citation source for that entry. + +--- + +## 3. Statutory text — relevant DPDP provisions + +The provisions reproduced below are the proximate statutory anchors for the question in §4. Counsel is asked to confirm the citations against the gazette-notified text in force as of the engagement-letter execution date. + +### 3.1 §2(t) — "personal data" + +> "personal data" means any data about an individual who is identifiable by or in relation to such data. + +The DPDP Act adopts a single definition for personal data; the EU GDPR's separation into "personal data" and "pseudonymised data" is not replicated. The identifiability test is read alongside the recitals and the rules notification. + +### 3.2 §2(u) — "personal information" + +Counsel to confirm the text. Our working understanding: `2(u)` provides the umbrella concept linking personal data to the data principal, and is the cross-reference for §§4-13. + +### 3.3 §2(o) — "identifiable" + +Counsel to confirm whether the Act provides a standalone definition or relies on §2(t)'s use of "identifiable." Our reading is that the Act treats identifiability functionally: data is "identifiable" if a natural person can be singled out from a population using the data alone or in combination with other data the fiduciary can reasonably access. + +### 3.4 §5 — notice to data principal + +§5 requires the data fiduciary to give the data principal a notice covering: the personal data being processed, the purpose, the manner of consent withdrawal, the manner of exercise of rights, and the manner of complaint to the DPB. The notice form is standardised by rules. Counsel to confirm rules-notification status as of v1. + +### 3.5 §8 — data breach reporting + +§8(6) obliges the data fiduciary to notify the DPB and affected data principals of every personal-data breach. The notification window is set by the rules; our working assumption is 72 hours from awareness, mirroring the GDPR Art. 33 cadence. Counsel to confirm the rules and whether "awareness" is to be read as "confirmation." + +### 3.6 §13 — cross-border transfer + +§13 empowers the central government to restrict the transfer of personal data outside India by notification. Our working assumption: replication to a non-Indian region of artefacts that are not "personal data" is not a §13 transfer; replication of artefacts that are personal data is a §13 transfer that may require a transfer-impact assessment. + +### 3.7 §17 — sensitive personal data + +Biometric data is treated as a category of personal data with elevated obligations. Counsel to confirm whether §17 imposes obligations *on the underlying biometric* (i.e., the input to our fuzzy extractor on the customer's device, which the bank never sees) or *on derivatives of the biometric* (i.e., the commitment, which the bank stores). + +### 3.8 §33 — penalties + +§33(1) sets the penalty cap for personal-data breaches at ₹250 crore per incident. The DPB has discretion to determine the actual quantum on a factor-weighted basis. Counsel to confirm whether the "commitments are not personal data" position, if accepted, removes the conduct from §33 jurisdiction or merely reduces the quantum. + +--- + +## 4. The legal question + +> **Are the (DID, commitment) tuples stored in the ZeroAuth tenant database "personal data" within the meaning of DPDP §2(t)?** + +A consequential question — to which the answer affects the bank's §5 notice obligations, §8 breach-reporting surface area, §13 cross-border restrictions, §17 sensitive-data treatment, and §33 penalty exposure — and a question on which we have a strong engineering view but no legal opinion of record. + +We frame the answer in two arguments: Argument-A (our hypothesis, which we ask counsel to confirm) and Argument-B (the conservative fallback, which describes the obligations even if Argument-A fails). + +--- + +## 5. Argument-A — the position we ask counsel to confirm + +**Claim.** The (DID, commitment) tuples are **not** personal data within the meaning of DPDP §2(t). + +The argument rests on four independent legs. Counsel is asked to evaluate each on its own and the conjunction as a whole. + +### 5.1 Leg (i) — Commitments are field elements with no direct semantic content + +The commitment is a single element in the prime-order group `Fr` of BN128. It is a number. It does not encode a name, an address, a phone number, an Aadhaar number, a PAN, a date of birth, a photograph, a biometric template, a behavioural trace, or any attribute that a human reading the database row could associate with the underlying data principal. + +A DPB reviewer pulling a commitment out of the `users` table sees `0x2f7a…b919`. The reviewer cannot, from that 32-byte string alone, deduce anything about the data principal. This is structurally different from a "hashed email" — hashed email is vulnerable to dictionary attack because the input space is small and known; the input to the Poseidon commitment is a fuzzy-extractor output over a high-entropy biometric capture, salted, and computed inside a circuit whose pre-image is not enumerable. + +### 5.2 Leg (ii) — The data principal is not "identifiable by or in relation to" the field element + +§2(t)'s identifiability test is the load-bearing clause. We submit that identification of the data principal from a (DID, commitment) tuple requires the joint possession of: + +- the commitment (which the bank stores); +- the salt (which the customer's device holds; never transmitted; never stored centrally); +- the secret (which is derived from on-device biometric capture; never transmitted; never stored centrally); +- the off-stack inversion of the Poseidon hash (which under current published cryptanalysis is computationally infeasible at the security parameter of BN128 — 128-bit security against generic attacks). + +In the absence of any of these four ingredients, no observer can perform identification. The fiduciary (the bank) does not possess them. The data principal does. Therefore, the data principal is not identifiable "by or in relation to" the field element from the fiduciary's vantage. + +### 5.3 Leg (iii) — The DID is an opaque, device-issued public identifier + +The DID is the leading 20 bytes of `keccak256(commitment)`. It inherits the opacity of the commitment: the DID does not encode any attribute of the natural person; it does not enable a directory lookup against an Aadhaar number, mobile number, or other UIDAI-issued identifier; it is not derivable from a public registry. + +A DID exposed in a database breach is not, on its own, a primitive that enables the attacker to impersonate the data principal: authentication requires the Groth16 proof, which requires possession of the secret and salt, neither of which the attacker has. + +### 5.4 Leg (iv) — Legislative intent and the §2(t) telos + +§2(t) is part of a statute whose preamble announces the purpose of protecting personal data. The mischief addressed is the identifiability of an individual from data held by a fiduciary. The legislative telos is to ensure that data fiduciaries do not, by their processing activities, expose natural persons to harm flowing from identification. + +A field element that, by cryptographic construction, does not enable identification of any natural person is outside this mischief. To read §2(t) as covering Pramaan commitments would expand the Act to cover artefacts whose entire engineering purpose is the elimination of personal-data risk — a reading that runs against the constructional canon of effective interpretation (Heydon's Rule, as adopted by the Supreme Court in *State of Karnataka v. Appa Balu Ingale* (1995) and reaffirmed in *RBI v. Peerless General Finance* (1987)). + +### 5.5 Anticipated DPB and counsel objections + +We invite counsel to test Argument-A against the following anticipated objections. + +- **Objection.** "Pseudonymous data is still personal data." + - Response. The DPDP Act, unlike the GDPR, does not adopt the term "pseudonymous." The identifiability test in §2(t) is a single threshold. Pseudonymous treatment under GDPR Art. 4(5) is a category that survives because identification with additional information held by the controller is possible; in our case the additional information (the secret) is on the data principal's device, not the controller's. +- **Objection.** "But the bank holds the device-attestation chain; in principle linkage is possible." + - Response. The device-attestation chain proves device integrity. It does not contain the biometric or the secret. The same response applies to the Play Integrity verdict. +- **Objection.** "Linkage to the bank's KYC artefact at enrollment makes this re-identifying." + - Response. The KYC artefact (Aadhaar dip, video KYC) is held in the bank's KYC system, not in the ZeroAuth tenant database. The link between the KYC artefact and the (DID, commitment) tuple is the `enrollment_audit_id`, a UUID. The audit row carries a `did_sha256` rather than the raw `did` (see threat-model entry A-22). The two systems are isolated by tenant ID and environment. Counsel is asked whether, on the totality of these isolations, the linkage risk crosses the §2(t) threshold for the ZeroAuth tenant database considered in isolation. +- **Objection.** "Even commitments tied to an authentication event leak metadata about the data principal." + - Response. The audit-log row carries timestamp + did_sha256 + event type. The fiduciary may treat this metadata as personal data for §2(t) purposes — a position we accept and discuss in Argument-B. The commitment in the `users` table is a separate artefact from the audit-log row. + +--- + +## 6. Argument-B — the conservative fallback + +**Claim.** Even if counsel concludes that the (DID, commitment) tuples are personal data, the data-fiduciary obligations under the Act are easily met and the §8 reportable-breach surface is materially reduced. + +This argument is the fallback the bank's General Counsel will want — a position that holds even if the regulator rejects Argument-A. + +### 6.1 §§6, 7 consent and lawful processing are easily satisfied + +The only meaningful processing of the commitment is **identity verification** for the data principal's own benefit. The processing is the proximate cause of the data principal's ability to access the bank's services. Consent at enrollment is informed (privacy notice scoped per A41-W1-Wed), specific (the consent text names the Pramaan protocol and lists the processing activities), and revocable (revocation triggers DID voidance and biometric re-enrollment elsewhere if the customer migrates). + +### 6.2 §8 breach-reporting surface is reduced + +A breach exposing the (DID, commitment) tuples does not expose the underlying biometric. It does not enable impersonation. The attacker who exfiltrates the entire `users` table cannot authenticate as any data principal because the secret remains in StrongBox on the device. + +The §8 notification, under the conservative reading, recites: + +- the categories of data exposed (commitments + DIDs); +- the cryptographic properties of those categories (hiding, binding, non-invertible at 128-bit security); +- the operational consequence (no impersonation primitive; no PII leakage); +- the mitigations already in place (audit-log hash chain, on-chain anchor, key revocation path). + +We submit that the DPB, presented with such a notification, will treat the incident as a low-harm breach for §33 quantum purposes — substantially below the cap of ₹250 crore. + +### 6.3 §17 sensitive-personal-data obligations attach to the input, not the output + +The biometric capture is sensitive personal data. The capture is on the customer's device, never transmitted. The fuzzy-extractor output is a derived secret that lives only on the device. The Poseidon commitment, derived from the secret, is a downstream artefact. Counsel is asked to confirm that §17's elevated obligations attach to the on-device capture (under the customer's own custody) and not to the central-database derivative — a distinction the Act does not yet draw explicitly. + +### 6.4 Comparative posture vs. incumbent BFSI auth platforms + +Even in the conservative reading, ZeroAuth's DPDP exposure is materially lower than that of: + +- **Auth0 / Okta / Cognito tenants:** which store password hashes, MFA seeds, recovery codes, and (in some BFSI deployments) Aadhaar OTP transcripts and KYC artefacts. A full breach of those tenants is a personal-data breach with broad §8 surface area. +- **Bank-owned biometric template stores:** which hold the raw biometric template (BFSI ABCC-compliant fingerprint vault). A breach yields a primitive that can be replayed on biometric matchers; ZeroAuth's breach yields field elements that cannot be replayed against the Groth16 verifier. + +This comparative posture is the commercial spine of the engineering pain-point catalogue: see P1 in `docs/plan/bfsi-v1/01-pain-points.md`. + +--- + +## 7. Counsel-engagement questions (open) + +The following are the six open questions we ask counsel to address in the v1 memo and to write a formal opinion on in v2. + +### Q1 — Defensibility of Argument-A in front of the DPB + +Is the position in §5 defensible if the DPB were to argue that commitments are personal data under §2(t)? + +- Sub-question. What is the burden of proof on the fiduciary to establish non-identifiability — does the fiduciary discharge it by producing a cryptographic-properties brief, or is an expert opinion required? +- Sub-question. Is there value in pre-emptively engaging the DPB through a consultative letter ahead of pilot launch, to surface their reading of §2(t) before a §8 incident forces the question? + +### Q2 — §5 minimum-viable notice if commitments are personal data + +If counsel rejects Argument-A, what is the minimum-viable notice under §5 that the bank must give to enrolled customers? Specifically: + +- (a) Must the notice describe the cryptographic operation (Poseidon commitment, BN128 group) or is "your biometric is processed via a zero-knowledge proof system" sufficient? +- (b) Must the notice quantify the breach blast radius, given the cryptographic properties? +- (c) Must the notice describe the on-chain anchor (Base Sepolia in pilot, Base mainnet in production), since this is data that crosses borders? +- (d) Is the notice required at enrollment only, or repeatedly at each authentication? + +### Q3 — §13 cross-border transfer treatment + +The pilot architecture replicates database content to a UK-resident or GCC-resident read replica for the bank's overseas operations (Phase 4 deliverable). The artefacts replicated are: `users` (commitments + DIDs), `device_registrations` (device-id hashes + Play Integrity verdicts + cert-chain hashes), `audit_events` (event types + did_sha256 + timestamps + hash-chain entries). + +- (a) If commitments are not personal data per Argument-A, is the replication of `users` and `device_registrations` outside §13? +- (b) Is the replication of `audit_events` — which contains timestamps and did_sha256 — within §13? +- (c) Does a transfer-impact assessment under §13 require a documented threat-model entry for each cross-border data category, and if so, what is the template? +- (d) Does the central government's notification of "restricted regions" under §13 apply per region or per data category, and is the UK currently restricted? + +### Q4 — §17 elevation via ABHA linkage in a future pilot + +A planned bank pilot (BFSI Phase 2, deferred) involves linking the ZeroAuth DID to an Ayushman Bharat Digital Mission (ABHA) health-identity number for the bank's bancassurance health-insurance underwriting flow. + +- (a) Does ABHA linkage elevate the (DID, commitment) tuple to sensitive personal data under §17? +- (b) If the ABHA number is stored on the bank side and only its keccak256 hash is exposed to ZeroAuth, does that change the §17 treatment? +- (c) What is the right consent regime for ABHA-linked authentication: the DPDP general consent, the NDHM-specific consent template, or a composite? + +### Q5 — §8 breach-notification timeline — "awareness" or "confirmation" + +The §8 notification window is to be set by rules (currently expected 72 hours per the draft notification). Within that: + +- (a) Does the clock start at the SOC alert (initial detection signal), the incident-commander confirmation (triage gate), or the forensic root-cause confirmation? +- (b) Does ZeroAuth's role as a sub-processor for the bank tenant create a back-to-back notification chain, where ZeroAuth notifies the bank within X hours and the bank notifies the DPB within (72 - X) hours? +- (c) Is the notification template (form, fields, channel) gazette-notified, and does it accommodate the "commitments are not personal data" assertion as a category in the notification body? + +### Q6 — Standard of care on the device-side SHA-256 of the biometric template + +Prior to the Poseidon commitment computation, the customer's device computes a SHA-256 of the biometric template. This SHA-256 exists briefly in RAM on the customer's device — not on any ZeroAuth-controlled infrastructure. It is then consumed by the fuzzy-extractor stage and the input buffer is GC'd. + +- (a) Is the SHA-256, while resident in RAM, "processed" by ZeroAuth as a data fiduciary, given that the code path is shipped in the ZeroAuth Banking app? +- (b) What is the standard of care expected: app obfuscation, anti-debug, certificate pinning, runtime-application-self-protection (RASP)? +- (c) Are there documented precedents (RBI inspection findings, DPB guidance, foreign comparative jurisprudence) on the in-RAM lifetime of sensitive data and the fiduciary's discharge of duty? +- (d) Counsel is asked to confirm whether ADR 0015's circuit-version lock — which freezes the fuzzy-extractor stage at a published, audited version — discharges this duty. + +--- + +## 8.

Limitations of this memo + +This memo carries the following load-bearing caveats. Bank General Counsels and the DPB are asked to read them before relying on any conclusion herein. + +- **Not a legal opinion.** Written by ZeroAuth engineering and compliance staff. The arguments in §5 and §6 are hypotheses formed against our reading of the statutory text. They are not the opinion of counsel and should not be treated as such until v2 lands with counsel's signature. +- **Not a substitute for the bank's own counsel.** Each pilot bank's General Counsel will form an independent view based on the bank's own pilot configuration, customer base, and regulatory posture. This memo is a starting point for that work, not an endpoint. +- **Snapshot in time.** The memo treats the Act as in force as of the latest gazette notification reviewed by counsel for v1. Rules notifications, DPB enforcement orders, and judicial pronouncements may modify §2(t)'s effective scope. Maintenance per §9.5 applies. +- **Engineering assumptions are version-bound.** Argument-A leans on the cryptographic properties of Poseidon, BN128, and Groth16 at the security parameter of the locked circuit version (`adr/0015-circuit-version-lock.md`). A circuit-version bump, a cryptanalytic advance against Poseidon, or a discovered weakness in BN128 invalidates Argument-A; this memo must be re-evaluated. +- **Scope: tenant database only.** The memo addresses the (DID, commitment) tuples in the ZeroAuth tenant `users` table. Audit-log artefacts, device-attestation chains, and KYC artefacts at the bank tenant's edge are addressed separately and may carry different §2(t) treatment. +- **Not adjudicated.** No DPB enforcement order or judicial pronouncement has yet addressed the §2(t) treatment of zero-knowledge proof commitments. The position in §5 is, to our knowledge, a question of first impression. + +--- + +## 11. Open dependencies + +The memo's progression to v2 is gated by external events tracked in `docs/compliance/dpdp/dependencies-tracker.md` (to be created). The current open dependencies are: + +- **DPB rules notification.** Status: pending. Tracked in the Phase 0 week 1 compliance check by Agent #37. Rules may modify the effective scope of §2(t), §8 (breach-window), and §13 (cross-border restrictions). Memo cannot advance to v2 without sight of the gazette-notified rules current at the date of counsel's opinion. +- **External counsel engagement letter.** Status: scoped Phase 0 week 1 (A37-W1-Thu), targeted signature Phase 0 week 3. Owner: Agent #37. The letter must capture the v2 written-opinion deliverable, the indemnification ceiling, and the scope of follow-on advice on §§8, 13, 17. +- **Bank General Counsel review.** Status: each pilot bank's GC reviews v1 and v2 independently before pilot signing. Owner: Agent #43 (north) and Agent #44 (south) at the AE level; Agent #37 supports. Bank GCs may surface bank-specific objections that we incorporate as appendices. +- **A-NN threat-model entry.** Status: to be added in the Phase-0 close-out PR. The entry will cross-reference this memo and the Pramaan whitepaper.

Ships the users-view component skeleton plus its PII-blacklist test ahead of the route wiring, so the structural no-PII contract is locked down before any wiring lands in App.tsx. What is here: dashboard/src/lib/users-api.ts TenantUserRow carries ONLY id, did, commitment, tenantId, environment, createdAt. listUsers() projects whatever the server hands back through an allowlist; PII columns the server still carries (full name, work email, phone, employee code per the schema-purity test at tests/schema-purity.test.ts) are dropped on the floor before they reach React. dashboard/src/routes/tenant/users.tsx UsersView component using @tanstack/react-query and the existing Card/Skeleton/EmptyState/Badge primitives. EXACTLY four columns: DID, Commitment (truncated to first 12 hex chars + ellipsis), Environment, Created at. The columns are an allowlist constant; widening it is an ADR-grade decision. No route registration yet — App.tsx wiring lands in the C-107 sprint 1 commit. dashboard/src/routes/tenant/__tests__/users.fixtures.ts Three fake TenantUserRow fixtures plus a parallel SENSITIVE_LEAK_PROBES tuple that names the substrings ('Alice', 'Bob', 'Charlie', '@example.com', '+91', 'EMP-') the test must never find in the rendered DOM. dashboard/src/routes/tenant/__tests__/users.test.tsx Five assertions covering: DID presence, PII-substring absence (including a generic phone-shape regex), source-file property-read scan ('.full_name' / '.email' / '.phone' / '.employee_code' must not appear in the component body), type-level enforcement via vitest's expectTypeOf, and an empty-state copy check. Why this is two halves of the same problem: - The server-side PII strip (the half owned by Agent #7 in C-107 sprint 1) removes the columns from the wire. Until then, the schema-purity test (tests/schema-purity.test.ts) locks down the current PG schema so no NEW PII columns sneak in. - The dashboard-side narrow type + projection here makes the surface area structurally inaccessible from the React tree regardless of what the server still sends — defence in depth. This is the engineering-side commitment to the DPDP §2(t) memo skeleton (docs/compliance/dpdp-2t-memo.md, drafted in parallel by the compliance line): the data principal is not identifiable by or in relation to a Poseidon commitment + opaque DID, and the dashboard cannot accidentally widen that surface. How to verify: cd dashboard && npm test -- src/routes/tenant/__tests__/users.test.tsx Five tests pass; full dashboard suite remains 36/36 green. Typecheck clean.

The admin auth middleware then compares against that snapshot at request time. When a test sets process.env.ADMIN_API_KEY inside beforeAll() the config object has already frozen the fallback ('dev-admin-key'), so every request is 403'd regardless of which key the test sends. tests/admin-audit-integrity.test.ts hit this on any worktree without a populated .env (CI, fresh clone) — 6 of its 7 assertions failed with 403 where they expected 200 or 400. Tests that read config.admin.apiKey directly after import (admin.test.ts, leads.test.ts, middleware.test.ts) were unaffected because they pick up whatever the config captured. Adding a jest setupFiles entry that fires before any module from the test file is imported is the standard fix — the env var lands first, config reads it, and the rest of the existing test code works as written.

One row per DB column (twelve tables in src/services/db.ts, including the audit_anchors row scheduled for Phase 1 C-016 backfill), every audit_events.metadata JSONB field, every API payload field, every Winston log field, every Caddy access-log field, the on-device transient SHA-256 of the biometric template (classified TRANSIENT-SECRET, retention 0), and the OPAQUE-CRYPTOGRAPHIC artefacts (commitment, DID, did_sha256). Classifications use the five-value taxonomy NON-PII / PII / SENSITIVE-PII (DPDP §17) / SECRET / OPAQUE-CRYPTOGRAPHIC + the TRANSIENT-SECRET edge case. - docs/compliance/privacy/pia-template-v0.md Privacy Impact Assessment template covering subject, PIA ID, authors + reviewers (DPO + privacy engineer + product role mandatory), description of processing, data flow diagram, data elements affected (referenced by inventory row ID), lawful basis under DPDP §6 + RBI sectoral, cross-border treatment, retention, five-risk likelihood × impact matrix, mitigations, residual risk acceptance signed by DPO + CCO, optional DPDP §5 notice updates, and threat-model rows touched. - docs/compliance/privacy/data-retention-policy-v0.md Default retention rules per classification (NON-PII 7 years, PII 3 years from last contact, SENSITIVE-PII 2 years, SECRET rotated quarterly, OPAQUE-CRYPTOGRAPHIC same as PII conservatively until counsel signs off on the §2(t) memo, TRANSIENT-SECRET 0 days), per-table retention table for every table in src/services/db.ts, bank-specific override JSON via tenants.security_policy.retention_overrides, nightly cleanup-job spec (implementation lands Phase 1 sprint 4), DPDP §13 right-to-erasure cascade flow, and the five exception classes (court order, regulator inspection, security investigation, bank audit, litigation hold). Cross-references: - The OPAQUE-CRYPTOGRAPHIC classification of commitments + DIDs + did_sha256 rests on the framework in docs/compliance/dpdp-2t-commitments-memo-v0.md §5 Argument-A. The retention policy holds these artefacts at the conservative PII bar until counsel signs off on memo v2. - The PII handling on audit_events.metadata + the desktop_ip / desktop_user_agent columns on proof_pairing_sessions traces to docs/threat_model.md A-22 (PII in pairing logs). - The 90-day Caddy access-log retention with query strings stripped on /api/console/* paths references docs/threat_model.md A-28 (JWT-in-URL log leak, CLOSED in C-005). - The schema-purity column allowlist in tests/schema-purity.test.ts is the source of the per-table column lists in §3 of the inventory.

Purpose + +This inventory establishes the **canonical catalogue of every data element ZeroAuth processes**, classified by sensitivity under DPDP §17, with the lawful basis (DPDP §6), the retention period, and the cross-border transfer status named per element. It is used as the **input to every Privacy Impact Assessment** (PIA-template-v0) and as the source of truth for the `tests/schema-purity.test.ts` column allowlist. + +When an engineering change introduces a new field, log line, or API surface, the PIA author looks up the element in this inventory. If the element is missing, a row must be added in the same PR that introduces the field, signed off by Agent #39 (Privacy) and Agent #41 (DPO). New rows that propose a new classification value (beyond the five enumerated below) require an ADR. + +The five classification values used throughout are: + +- **NON-PII** — opaque IDs (UUIDs), system-generated counters, configuration values, timestamps not bound to a single natural person. +- **PII** — data that identifies, or is reasonably likely to identify, a natural person under DPDP §2(t). Examples: name, email, phone, employee code, IP address paired with a session. +- **SENSITIVE-PII** — the DPDP §17 category for elevated-obligation personal data. Biometric data is the canonical example. ZeroAuth never holds raw biometric data centrally; SENSITIVE-PII rows in this inventory describe the on-device-only artefacts within ZeroAuth code paths (see Q6 in dpdp-2t-commitments-memo-v0.md §7). +- **SECRET** — credentials and key material whose disclosure to an unintended party degrades the system's authentication or integrity guarantees. Examples: password hashes, API-key SHA-256 hashes, JWT signing secret, session-bind cookie value, contract owner private key. +- **OPAQUE-CRYPTOGRAPHIC** — artefacts that have been constructed under a hiding-and-binding commitment scheme or a one-way function such that they do not identify a natural person under §2(t) by the argument in `dpdp-2t-commitments-memo-v0.md` §5. Examples: Poseidon commitment, DID, did_sha256 in audit metadata. +- **TRANSIENT-SECRET** — secret material that exists only in RAM on the customer's own device for the duration of a single proof-generation operation and is then garbage-collected. The SHA-256 of the biometric template is the canonical example. ZeroAuth ships the code path that produces this material; the bank's tenant database never holds it. + +Cross-border status is named per element: **Indian-only** (lives on the Mumbai VPS + Hyderabad DR replica only) or **shipped-out** (replicated to a non-Indian region or processed by a non-Indian processor, with destination named). + +--- + +## 2. Methodology + +This inventory was produced by walking every surface that handles data: + +1. **Every table in `src/services/db.ts`** — twelve table definitions enumerated below. Every column captured. +2. **Every audit-event metadata field** — by inspecting `src/services/audit.ts` and the call sites that build the `metadata` JSONB. The canonical fields are `did_sha256`, `actor_email`, `ip_address`, `user_agent`, `requested_scope`, `failure_reason`, `verification_id`, `device_id`, `session_id` and free-form per-event extensions. +3. **Every API payload field** — by inspecting the request and response interfaces in `src/types/` and the route handlers under `src/routes/`. The inventory captures the fields that cross the network boundary. +4. **Every Winston log field** — by inspecting `src/services/usage.ts` (request logger), `src/middleware/error-handler.ts` (error logger), and the structured-logging conventions across services. Winston records `requestId`, `path`, `tenantId`, `apiKeyId`, status code, response time. Body content is **not** logged (A-22 mitigation). +5. **Every Caddy access-log field** — by inspecting `Caddyfile`. Caddy records source IP, method, path (no query string under the C-005 closure for `/api/console/*`), user agent, response status, bytes, duration. +6. **On-device, transient elements** — the SHA-256 of the biometric template that lives in RAM on the customer's phone during proof generation. Captured here because ZeroAuth ships the code that computes it, even though it never leaves the device (Q6 in `dpdp-2t-commitments-memo-v0.md` §7). +7. **The OPAQUE-CRYPTOGRAPHIC artefacts** — the Poseidon commitment and the DID, classified per the §2(t) memo argument. + +The walk is committed to source so the audit trail is reviewable. Every PR that touches `src/services/db.ts`, audit metadata fields, log fields, or API surfaces must update this inventory in the same commit; CI lints for column drift against the allowlist locked into `tests/schema-purity.test.ts`. + +--- + +## 3.

Purpose + +This policy establishes the **canonical retention rules** for every data element ZeroAuth holds. The rules are organised in two layers: + +- **Default retention by classification** — applies when no table- or bank-specific override is in force. +- **Per-table retention** — explicit retention for every table in `src/services/db.ts`. +- **Bank-specific overrides** — per-tenant `security_policy.retention_overrides` JSON (already wired through the `tenants.security_policy` column; the schema-purity test allowlists it as a permissive JSONB). + +The policy is enforced by a nightly cleanup job (Phase 1 sprint 4 implementation; this document is the spec). Bank-tenants that require longer retention pass it through their per-tenant policy JSON; bank-tenants that require shorter retention than the default pass it the same way, subject to a sanity floor (no retention shorter than the regulator-mandated minimum on any audit-touching surface). + +The right-to-erasure flow (DPDP §13) operates orthogonally: a data-principal request triggers an admin-portal action that cascades a `DELETE` and writes an audit row, regardless of whether the retention timer has elapsed. + +--- + +## 2. Default retention by classification + +The classification values are the same five used in `data-inventory-v1.md` §1. The defaults below apply unless a per-table rule (§3) or a bank-specific override (§4) is more specific. + +| Classification | Default retention | Basis | +|---|---|---| +| **NON-PII** | **7 years (2555 days)** | Aligned with the audit-log baseline. NON-PII data is statutorily safe to keep for the longer of the audit horizon and the operational horizon; the audit horizon is the binding constraint on tenant-scoped tables (RBI IT MD §6.4). | +| **PII** | **3 years from last contact** | DPDP §6 (storage limitation principle) + RBI KYC MD §38 (5-year storage of KYC records counts only against KYC artefacts at the bank — ZeroAuth holds none — so the lower 3-year bar applies to ZeroAuth's PII). Erasable on data-principal request per DPDP §11 / §13. | +| **SENSITIVE-PII (DPDP §17)** | **2 years from last contact** | DPDP §17 imposes elevated obligations; the conservative reading is shorter retention. Erasable on request. ZeroAuth holds zero SENSITIVE-PII centrally; this default applies to on-device SENSITIVE-PII covered by Q6 in the §2(t) memo. | +| **SECRET** | **Rotated quarterly; never persisted beyond rotation** | JWT signing secret, session-bind cookie material, admin x-api-key. Rotation cadence captured in `docs/security/secret-rotation-runbook.md` (to be written, Phase 1 sprint 3 deliverable). | +| **OPAQUE-CRYPTOGRAPHIC (commitments, DIDs)** | **Same as PII (3 years from last contact)**, conservatively, until counsel signs off on the §2(t) memo | The §2(t) memo argues these artefacts are not personal data and can be retained without DPDP §6 limitation. The conservative posture treats them as PII until counsel confirms Argument-A. On counsel sign-off (memo v2), the retention promotes to NON-PII (7 years). | +| **TRANSIENT-SECRET** | **0 days** | Must be GC'd within the request lifetime. Verified by the biometric-payload-key blocklist (C-022) and the `device.sha256_biometric_template` field in `data-inventory-v1.md` §3.14. | + +The "from last contact" idiom means: the retention timer resets on every legitimate-purpose touch (a successful verification, an admin action initiated by the same principal). When the timer elapses with no touch, the cleanup job deletes the row and writes an audit-event with action `retention_expired_deletion`. + +--- + +## 3. Per-table retention table + +The table below resolves the default-by-classification rules against the specific tables. Where the table holds mixed classifications, the row carries the binding rule (typically the longest, since column-level deletion is operationally hard inside a single row). + +| Table | Retention (days) | Rule source | Notes | +|---|---|---|---| +| `leads` | 1095 (3 years) | PII default | Marketing lead capture; deleted on data-principal request via the admin portal. | +| `tenants` | -1 (lifetime of business relationship) | Service-relationship retention | Deleted on tenant offboarding; cascades to `api_keys`, `usage_logs`, `usage_monthly`, `devices`, `tenant_users`, `verification_events`, `attendance_events`, `audit_events`. | +| `pending_signups` | 1 (24 hours TTL) | Operational TTL | Hard TTL; rows older than 24h that have not been consumed are deleted by the cleanup job. | +| `api_keys` | -1 (lifetime of tenant) | Service-relationship retention | Revoked keys are retained for audit purposes; `revoked_at` is the operational timer for any policy that prunes revoked keys after 1 year (not yet enabled). | +| `usage_logs` | 540 (18 months) | Billing horizon | Billing dispute window plus a 6-month buffer. | +| `usage_monthly` | 2555 (7 years) | Audit horizon | Aggregated counters; retained for the audit horizon for financial reporting. | +| `devices` | -1 (lifetime of tenant) | Service-relationship retention | Retired devices retained for audit traceability; pruned on tenant offboarding. | +| `tenant_users` | -1 (lifetime of relationship; PII columns scheduled for removal in Phase 1 PII-strip) | Conservative until Phase 1 PII-strip lands | After Phase 1 PII-strip, this row reads `7 years (2555 days)` because the remaining columns are NON-PII + OPAQUE-CRYPTOGRAPHIC. Tracked as a roadmap deliverable. | +| `verification_events` | 2555 (7 years) | RBI IT MD §6.4 (audit logs) | Aligned with the audit-event retention; required for bank-side §6.4 evidence. | +| `attendance_events` | 2555 (7 years) | Audit horizon | Aligned with verification_events. | +| `proof_pairing_sessions` | 30 (30 days) | Operational + abuse-defence | 5-min TTL on `state=issued` (cleanup job); 30 days on `state IN (consumed,failed,expired)` for fraud-investigation tail. | +| `audit_events` | 2555 (7 years) | RBI IT MD §6.4 + DPDP §8 baseline | Append-only; the hash chain (ADR 0013) ensures any deletion is detectable. The cleanup job that prunes rows older than 7 years must also extend the chain forward (covered by ADR 0013 §rolling-genesis). | +| `audit_anchors` | 2555 (7 years; on-chain anchor is permanent) | Audit horizon | The DB row is purged at 7 years; the on-chain anchor lives forever on Base mainnet (Phase 4 deployment). | + +--- + +## 4. Bank-specific retention overrides + +Each bank-tenant can pass a `retention_overrides` map through `tenants.security_policy` JSONB. The map keys are table names; the values are objects with `retention_days` and optional `last-contact-field` overrides. Example for Anchor Bank, which requires the legally maximal 7-year retention on every audit-touching surface and the regulator-mandated 5-year retention on transactional surfaces: + +```json +{ + "retention_overrides": { + "audit_events": { "retention_days": 2555 }, + "verification_events": { "retention_days": 1825 }, + "attendance_events": { "retention_days": 1825 }, + "usage_logs": { "retention_days": 1095 }, + "tenant_users": { "retention_days": -1 } + } +} +``` + +The cleanup job consults `tenants.security_policy.retention_overrides` first; if absent, it falls back to the §3 table. The override may only **lengthen** retention on audit-touching surfaces relative to the defaults; an override that proposes a shorter retention on any audit-touching surface is rejected at policy-load time with a `policy_violation` audit row. + +The schema-purity test (`tests/schema-purity.test.ts`) does not yet inspect `security_policy` JSONB schemas; an ADR will be raised to lock that JSONB schema down once the override surface is in use across more than one tenant. + +--- + +## 5. Nightly cleanup job (proposed spec — implementation Phase 1 sprint 4) + +A nightly cron at 02:00 IST runs the cleanup job. The job: + +1. Loads the per-tenant `retention_overrides` map for every active tenant. +2. For each table in §3 with a finite retention period: + - Computes the effective `retention_days` (override or default). + - Executes a parameterised SQL `DELETE` of rows older than `now() - retention_days * INTERVAL '1 day'`. + - Counts deleted rows; logs the count to `audit_events` with action `retention_cleanup`, summary "rows deleted by retention policy". +3. For `audit_events` specifically: + - The delete extends the hash chain forward by writing a `chain_rolling_genesis` event whose `previous_hash` is the last hash before the deletion window. This preserves the chain across the prune. +4. Hard failure modes: + - If the `DELETE` query exceeds 30 seconds, the job aborts and pages the on-call engineer. + - If the count of deleted rows exceeds 5% of the table size in a single run, the job aborts and pages. +5. Soft failure modes: + - Job runtime > 10 minutes total → warning logged. + - Override JSONB that fails the policy guard (§4) → row dropped from this run + policy-violation audit row. + +The implementation lands in Phase 1 sprint 4; the C-IDs are reserved as `C-141..C-146` (allocated in `docs/plan/bfsi-v1/04-commits.md` placeholder). + +--- + +## 6. Right-to-erasure flow (DPDP §13) + +Per DPDP §13, a data principal may request erasure of their personal data. The flow: + +1. **Request capture.** The data principal writes to the bank-tenant's grievance officer (per the bank's DPDP §6 notice). The grievance officer files an admin-portal request keyed by `did` or by `external_id` (depending on which the bank operates with). +2. **Lookup.** The admin portal locates the `tenant_users` row by `tenant_id + environment + external_id` (or by `tenant_id + environment + did` once the Phase 1 PII-strip lands). +3. **Cascade.** The system performs a transactional delete: + - Delete the `tenant_users` row. + - Cascade-null the `verification_events.user_id` and `attendance_events.user_id` FKs (set to NULL by the existing `ON DELETE SET NULL`). + - Delete the on-device-issued `cookie.zeroauth_console_jwt` if the data principal also held a console account (rare case). + - Cascade-delete by FK any other rows referencing the user. +4. **Audit.** Write an `audit_events` row with `action = 'erasure_dpdp_13'`, `entity_type = 'tenant_user'`, `entity_id = `, `actor_type = 'console'`, `actor_id = `, `metadata = { reason: 'data_principal_request', request_id: }`. +5. **Confirmation.** The grievance officer receives a confirmation that the cascade ran successfully, including the audit-event ID. +6. **Tombstone.** The bank-tenant retains a tombstone record outside ZeroAuth that says "user X was erased on YYYY-MM-DD"; this tombstone is the bank's evidence of compliance and is not stored in ZeroAuth's database. + +**Exception classes (§7) override the cascade where they apply.** + +The right-to-erasure flow is exercised quarterly as part of the DPDP §13 tabletop (Q3 week 33 first exercise per `compliance-roadmap-v1.md` §3.3). The first tabletop is the operational proof that the cascade is intact; subsequent exercises verify drift. + +--- + +## 7. Exception classes + +The following classes **block** the cleanup job and the right-to-erasure cascade for the affected rows. Each class requires an audit-events row of class `retention_hold` at the time the hold is applied, with the legal/operational basis cited. + +### 7.1 Court-ordered data hold + +A court order (Indian or, where Indian law gives effect, a foreign court) compels retention of specific rows beyond their retention timer or against a data-principal erasure request. The hold is applied by: + +- Writing a `retention_holds` row (table to be added in Phase 1 sprint 4) keyed by `(tenant_id, target_table, target_pk)` with `hold_type = 'court_order'`, `case_reference`, `hold_until`. +- Marking the affected row(s) with a JSONB flag `metadata.retention_hold = true`. + +The cleanup job and the erasure cascade both honour the flag and skip the affected rows. When the hold lapses (court order vacated, hold_until reached), the flag is cleared and the rows return to the normal retention regime. + +### 7.2 Regulator inspection + +An RBI inspection, a DPB inquiry, or any other regulator action that requires the preservation of specific records beyond their retention timer. The hold mechanism is the same as §7.1 with `hold_type = 'regulator_inspection'` and the inspection reference. + +The hold is applied by the CCO (Agent #36) on advice of counsel; the hold cannot be applied by an engineering action alone. + +### 7.3 Ongoing security investigation + +A live security incident under investigation by Agent #26 (Security red-team), Agent #21 (SRE), or an external incident-response vendor. Hold type `security_investigation` with the incident reference. + +Holds in this class default to 90 days and are extended only on written advice of the incident commander. They are reviewed at every quarterly access review (`compliance-roadmap-v1.md` §4.2 D-Q2-12) for stale entries. + +### 7.4 Pending bank-side audit + +A bank-tenant's internal audit team has requested preservation of specific records for an audit cycle. Hold type `bank_audit` with the audit reference. Defaults to 180 days; extended by mutual agreement. + +### 7.5 Litigation hold + +A litigation hold notice from any party with standing (a customer, a regulator, a co-defendant). Hold type `litigation_hold` with the matter reference. Defaults to the duration of the matter as advised by counsel. + +--- + +## 8. Audit + observability + +Every action that touches retention writes an audit row. The actions are: + +- `retention_cleanup` — nightly cleanup ran successfully. +- `retention_expired_deletion` — individual row deleted by retention timer (folded into the daily cleanup audit row to avoid log explosion; sampled at 1 in 100 for individual rows). +- `retention_hold_applied` — a hold under §7 was applied. +- `retention_hold_lifted` — a hold was lifted. +- `erasure_dpdp_13` — a right-to-erasure cascade was executed. +- `retention_policy_violation` — a bank-tenant `retention_overrides` was rejected at policy-load time. + +The `/api/admin/privacy-audit` endpoint (already shipped) surfaces these rows for inspection. The retention-cleanup-summary view (to be added in Phase 1 sprint 4) aggregates the rows by tenant + table for quarterly review by the DPO. + +--- + +## 9. Open questions referred forward + +- **Q-RET-01.** Should the OPAQUE-CRYPTOGRAPHIC default be promoted to NON-PII (7-year retention) on counsel sign-off of the §2(t) memo, or do we hold at PII-equivalent retention pending a regulator interaction? Referred to Agent #41 + counsel via memo v2. +- **Q-RET-02.** Does the `pending_signups` 24-hour TTL satisfy DPDP §6 storage-limitation, or should we shorten to 1 hour after the verify link is consumed? Operational impact is minor; security upside is small. Decision deferred to Phase 1 sprint 3. +- **Q-RET-03.** Should `usage_logs.ip_address` be hashed after 90 days (preserving abuse-defence histograms but losing the raw IP for re-identification)? Referred to Agent #6 + Agent #39; ADR target Phase 1 sprint 4. +- **Q-RET-04.** The right-to-erasure cascade currently leaves orphan rows in `verification_events` (FK `SET NULL`). Is this consistent with DPDP §13 erasure, or must we delete the `verification_events` row outright? Referred to counsel via memo v1. +- **Q-RET-05.** The `audit_events.metadata.actor_email` field — captured during console actions — is a PII surface on what is otherwise a NON-PII / OPAQUE row. Should the email be replaced with a `console_user_id` UUID lookup on a separate table, with the email queryable only via the admin portal? Referred to Agent #14 + Agent #39 for Phase 1 sprint 2 design. + +--- + +LAST_UPDATED: 2026-05-28 +OWNER: Agent #39 (Privacy) + Agent #41 (DPO) diff --git a/docs/compliance/privacy/pia-template-v0.md b/docs/compliance/privacy/pia-template-v0.md new file mode 100644 index 0000000..c3dc553 --- /dev/null +++ b/docs/compliance/privacy/pia-template-v0.md @@ -0,0 +1,198 @@ +# Privacy Impact Assessment — template v0 + +**Status:** v0 — first issue.

Lands four Gradle modules: :app — Activity, Compose UI, placeholder surface rendering 'ZeroAuth — coming soon (scaffold C-101)'. minSdk 30, targetSdk 34, Kotlin 1.9.22, AGP 8.3.2, Compose BOM 2024.02.02, applicationId dev.zeroauth.banking, versionCode 1 / versionName 0.1.0. :prover — interface-only library. Prover.kt declares generateProof(witnessJson) -> proofJson; DefaultProver throws NotImplementedError. The rapidsnark JNI bridge implementation lands with C-104 per the Agent #17 plan (docs/plan/bfsi-v1/agents/agent-17-android-prover.md ticket A17-W3-Mon). :sensors:r307 — interface-only library for the R307 USB-OTG fingerprint sensor. Driver lands with C-145. :sensors:biometric_prompt — interface-only library for the platform BiometricPrompt + StrongBox key wrap. Real invocation + class-3 enforcement land with C-144. The subtree is deliberately parallel to the existing android/ subtree (the W3 desktop-login WebView spike): different toolchain pin (android/ is Kotlin 2.0 + AGP 8.5; mobile/ is Kotlin 1.9.22 + AGP 8.3.2), different applicationId (dev.zeroauth.android vs dev.zeroauth.banking), different settings.gradle.kts root. They coexist for the W3-to-W4 transition; once C-104 lands the rapidsnark JNI bridge here the W3 WebView path becomes a tier-2 fallback and mobile/ is the authoritative implementation. Why this commit ships only a scaffold: * gives downstream commits (C-104 prover, C-143 enrollment, C-144 keystore, C-145 R307, C-146 e2e login) a place to land without each one re-litigating module boundaries; * exercises the module graph end-to-end (:app depends on all three siblings from day one) so each implementation drop is a module-internal change rather than a wiring change; * the four pinned versions (Kotlin/AGP/Compose-BOM/compose-compiler) are intentionally a stable older quartet — the toolchain bump is re-evaluated once the rapidsnark JNI build stabilises post-C-104. Reference artefacts the scaffold is designed against: * docs/plan/bfsi-v1/02-bank-demo.md — Scenes 1 (enrollment) + 2 (kiosk login) drive the eventual flows in :app. * docs/operations/device-support-matrix.md — minSdk 30 + StrongBox + class-3 BiometricPrompt requirements come from the tier-1 row constraints + the tier-3 denylist. * docs/plan/bfsi-v1/agents/agent-17-android-prover.md ticket A17-W2-Mon — this commit is the explicit deliverable. * docs/plan/bfsi-v1/agents/agent-04-vp-mobile.md ticket A04-W3-Tue — the reviewer-side review of this PR. New dependencies introduced (AndroidX core/lifecycle/activity, Compose BOM + UI + Material 3 + Tooling, AndroidX test runners + Compose UI test JUnit4): these are intrinsic to the Android-only platform choice. The platform-level rationale is covered by adr/0010-android-webview- snarkjs-bundling.md (the existing Android-only commitment in this tree) and is being broadened in adr/0014-android-only-mobile-platform.md as C-102 lands in week 3 (per docs/plan/bfsi-v1/agents/agent-04-vp-mobile.md ticket A04-W1-Tue). No new ADR is opened with this commit — the platform dep ADR trail is in flight on the C-102 PR. Verification at commit time: * find mobile -name '*.kt' -o -name '*.kts' -o -name '*.xml' lists 31 files spanning all four modules. * 31 files / 1412 lines total. * The Gradle wrapper jar is NOT committed; it lands in the follow-on CI-wiring commit. No attempt is made to compile the project locally — that runs in CI once the workflow exists. --- .gitignore | 10 ++ mobile/.gitignore | 38 +++++ mobile/README.md | 122 +++++++++++++++ mobile/app/build.gradle.kts | 142 ++++++++++++++++++ mobile/app/proguard-rules.pro | 31 ++++ .../dev/zeroauth/SmokeInstrumentedTest.kt | 42 ++++++ mobile/app/src/main/AndroidManifest.xml | 44 ++++++ .../main/kotlin/dev/zeroauth/MainActivity.kt | 78 ++++++++++ .../dev/zeroauth/ZeroAuthApplication.kt | 42 ++++++ .../kotlin/dev/zeroauth/ui/theme/Theme.kt | 80 ++++++++++ .../res/mipmap-anydpi-v26/ic_launcher.xml | 20 +++ mobile/app/src/main/res/values/colors.xml | 11 ++ mobile/app/src/main/res/values/strings.xml | 11 ++ mobile/app/src/main/res/values/themes.xml | 25 +++ .../main/res/xml/data_extraction_rules.xml | 36 +++++ .../test/kotlin/dev/zeroauth/SmokeUnitTest.kt | 45 ++++++ mobile/build.gradle.kts | 14 ++ mobile/gradle.properties | 36 +++++ mobile/gradle/libs.versions.toml | 81 ++++++++++ mobile/prover/README.md | 30 ++++ mobile/prover/build.gradle.kts | 62 ++++++++ mobile/prover/src/main/AndroidManifest.xml | 12 ++ .../main/kotlin/dev/zeroauth/prover/Prover.kt | 73 +++++++++ mobile/sensors/biometric_prompt/README.md | 35 +++++ .../sensors/biometric_prompt/build.gradle.kts | 44 ++++++ .../src/main/AndroidManifest.xml | 8 + .../biometric/BiometricPromptFallback.kt | 64 ++++++++ mobile/sensors/r307/README.md | 30 ++++ mobile/sensors/r307/build.gradle.kts | 40 +++++ .../sensors/r307/src/main/AndroidManifest.xml | 9 ++ .../dev/zeroauth/sensors/r307/R307Driver.kt | 54 +++++++ mobile/settings.gradle.kts | 53 +++++++ 32 files changed, 1422 insertions(+) create mode 100644 mobile/.gitignore create mode 100644 mobile/README.md create mode 100644 mobile/app/build.gradle.kts create mode 100644 mobile/app/proguard-rules.pro create mode 100644 mobile/app/src/androidTest/kotlin/dev/zeroauth/SmokeInstrumentedTest.kt create mode 100644 mobile/app/src/main/AndroidManifest.xml create mode 100644 mobile/app/src/main/kotlin/dev/zeroauth/MainActivity.kt create mode 100644 mobile/app/src/main/kotlin/dev/zeroauth/ZeroAuthApplication.kt create mode 100644 mobile/app/src/main/kotlin/dev/zeroauth/ui/theme/Theme.kt create mode 100644 mobile/app/src/main/res/mipmap-anydpi-v26/ic_launcher.xml create mode 100644 mobile/app/src/main/res/values/colors.xml create mode 100644 mobile/app/src/main/res/values/strings.xml create mode 100644 mobile/app/src/main/res/values/themes.xml create mode 100644 mobile/app/src/main/res/xml/data_extraction_rules.xml create mode 100644 mobile/app/src/test/kotlin/dev/zeroauth/SmokeUnitTest.kt create mode 100644 mobile/build.gradle.kts create mode 100644 mobile/gradle.properties create mode 100644 mobile/gradle/libs.versions.toml create mode 100644 mobile/prover/README.md create mode 100644 mobile/prover/build.gradle.kts create mode 100644 mobile/prover/src/main/AndroidManifest.xml create mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/Prover.kt create mode 100644 mobile/sensors/biometric_prompt/README.md create mode 100644 mobile/sensors/biometric_prompt/build.gradle.kts create mode 100644 mobile/sensors/biometric_prompt/src/main/AndroidManifest.xml create mode 100644 mobile/sensors/biometric_prompt/src/main/kotlin/dev/zeroauth/sensors/biometric/BiometricPromptFallback.kt create mode 100644 mobile/sensors/r307/README.md create mode 100644 mobile/sensors/r307/build.gradle.kts create mode 100644 mobile/sensors/r307/src/main/AndroidManifest.xml create mode 100644 mobile/sensors/r307/src/main/kotlin/dev/zeroauth/sensors/r307/R307Driver.kt create mode 100644 mobile/settings.gradle.kts diff --git a/.gitignore b/.gitignore index e070f6e..cf48c66 100644 --- a/.gitignore +++ b/.gitignore @@ -32,6 +32,16 @@ artifacts/ cache/ typechain-types/ +# ─── Android (mobile/ — Phase 1 banking app, C-101 onwards) ─── +# Duplicates the rules in mobile/.gitignore so an accidental top-level +# `git add .` outside the subtree still skips the noisy artefacts. +mobile/.gradle/ +mobile/local.properties +mobile/**/build/ +mobile/**/.cxx/ +mobile/**/*.keystore +mobile/**/*.jks + # ─── Coverage / logs ──────────────────────────────────── coverage/ *.log diff --git a/mobile/.gitignore b/mobile/.gitignore new file mode 100644 index 0000000..b9c1501 --- /dev/null +++ b/mobile/.gitignore @@ -0,0 +1,38 @@ +# mobile/.gitignore — keep the Android workspace clean of build artefacts, +# IDE noise, and (most importantly) signing material that would burn a real +# release if it ever landed in the repo.

They coexist — `android/` is the test bench, `mobile/` is the +real banking app. Once C-104 lands the rapidsnark JNI bridge in this +tree, the W3 WebView path becomes a fallback for tier-2 devices and the +authoritative implementation lives here. + +## Module map + +| Module | Owner | What it does | Implementation lands | +|---|---|---|---| +| `:app` | Agent #17 (prover) + Agent #19 (UX) | The Pramaan banking app: Activity, Compose UI, enrollment + login + transaction-step-up flows. | C-101 scaffold; C-143, C-146, C-167 implementation. | +| `:prover` | Agent #17 | rapidsnark JNI bridge — produces Groth16 proofs against `identity_proof.circom` v1.2. | C-101 scaffold; C-104 implementation. | +| `:sensors:r307` | Agent #18 | R307 fingerprint sensor driver over USB-OTG host mode. | C-101 scaffold; C-145 implementation. | +| `:sensors:biometric_prompt` | Agent #17 | Android `BiometricPrompt` class-3 fallback with StrongBox-bound `CryptoObject`. | C-101 scaffold; C-144 implementation. | + +The Compose `:app` module consumes all three sibling modules from day +one so the C-104 / C-144 / C-145 implementation drops are +module-internal changes and do not require re-wiring across module +boundaries. + +## Build commands + +```bash +# Assemble the debug APK. +./gradlew :app:assembleDebug + +# Run the JVM-side unit tests (fast — no emulator needed). +./gradlew :app:test + +# Run the instrumented tests on a connected device or emulator. +./gradlew :app:connectedAndroidTest + +# Per-module test invocations once C-104 / C-144 / C-145 land: +./gradlew :prover:connectedAndroidTest +./gradlew :sensors:r307:connectedAndroidTest +./gradlew :sensors:biometric_prompt:connectedAndroidTest +``` + +The Gradle wrapper itself (`gradlew`, `gradlew.bat`, `gradle-wrapper.jar`) +is not committed at C-101; it lands once the CI workflow that exercises +`mobile/` is wired up in the next commit.

The Anchor Bank bank-demo runbook's Scene 2 ("login at a kiosk") opens with a full-screen QR already on the projector when the operator presents. This commit lands the React skeleton the sprint-2 integration commit picks up. dashboard/src/routes/kiosk/Kiosk.tsx is the page component. On mount it generates a 32-byte hex session_nonce, opens a pairing session via api.pairing.createSession, renders an api.qrserver.com-backed QR full-screen (high contrast, readable at 3m), and subscribes to the SSE stream. On the pairing.consumed event it redirects to the placeholder landing route at /anchor-bank/landing; on pairing.expired it silently mints a fresh session so the kiosk never shows a "session expired" card to the bank floor. The SSE consumer in kioskStream.ts deliberately bypasses the shared api.pairing.subscribeStream helper. Per ADR 0013 (and commit ee6aad4, "remove access_token query fallback from console SSE auth"), the HttpOnly zeroauth_console_jwt cookie is the only allowed transport for the JWT on the SSE stream — query-string tokens leak to Caddy access logs and become a session-replay primitive for the JWT's TTL. The shared helper still ships an ?access_token= query fallback for the W3 QR-pair demo; constructing the EventSource here, with withCredentials: true and no query string, makes the kiosk's ADR-0013 compliance enforceable from a single file even if the shared helper regresses. dashboard/src/routes/kiosk/KioskRoute.ts is the route descriptor (/kiosk/:tenant?session=...) the sprint-2 integration commit imports. App.tsx and the AppShell nav are intentionally NOT modified — wiring the kiosk into the dashboard router lands with C-147 sprint 2. The vitest suite at __tests__/Kiosk.test.tsx covers the four required assertions: (1) QR mounts after the createSession POST resolves, (2) the QR payload exposes session_nonce + tenant + expires_at, (3) the pairing.consumed SSE event triggers navigation to the landing route, (4) the pairing.expired SSE event creates a fresh session. A fifth belt-and-braces assertion covers the operator-recoverable error panel + retry path. dashboard/src/lib/api.ts and dashboard/src/lib/sse.ts are unchanged — the kiosk uses api.pairing.createSession (already shared with the existing W3 QR-pair demo) and a kiosk-local EventSource wrapper.

Lands three pieces of the future view in skeleton form so the structural contract is locked down before C-123 wires the route into App.tsx. 1. dashboard/src/components/IntegrityCheckCard.tsx — presentational card with three terminal states (pass / fail / pending). PASS shows a green check, 'Chain intact' headline, row count + last-checked timestamp. FAIL shows a red X, 'Chain broken at row #<brokenAt>' headline, the verbatim server reason and an Investigate button (no-op for now). Includes an optional 'Anchor: tx <hash>' sub-row with a clickable Basescan link (sepolia.basescan.org/tx/<hash>); the sub-row is hidden when anchor data is undefined. 2. dashboard/src/lib/audit-integrity-api.ts — typed client for GET /api/admin/audit-integrity. Maps the server's discriminated pass/fail wire shape (defined in src/routes/admin.ts at commit d634b2d) into the dashboard's IntegrityResult union. lastChecked is stamped on the client; rowsChecked is derived from the server's limit field until C-123 widens the response contract. 3. dashboard/src/routes/tenant/audit-integrity.tsx — AuditIntegrityView that wires useQuery to the client, renders the card, and exposes a 'Check now' button that triggers refetch. Below the card it reserves a labelled placeholder for the audit-anchors sub-view that lands in C-124 (a separate ticket). Tests: - dashboard/src/components/__tests__/IntegrityCheckCard.test.tsx (3 tests, one per terminal state; verbatim-reason rendering is the load-bearing assertion for Scene 5's narrative). - dashboard/src/routes/tenant/__tests__/audit-integrity.test.tsx (5 tests: initial pending, PASS render, FAIL render with brokenAt + reason, 'Check now' triggers refetch, and a source-file scan that the component contains zero .full_name / .email / .phone property reads — defence in depth even though this surface holds only audit metadata). ADR 0013 defines the hash-chain construction; ADR 0014 defines the on-chain anchor cadence whose tx hash the optional anchor sub-row links to on Basescan. The view does not modify App.tsx — wiring lands in C-123.

The deck itself is rendered in Keynote / Google Slides separately; this storyboard captures what each slide must communicate, how long the operator speaks to it, and which pain point, demo scene, engineering artefact, and compliance milestone it traces to. Treat the storyboard as the contract — if a slide deviates from what is recorded here in the rendered deck, the storyboard wins and the deck is corrected. + +The 20 slides below back the 22-minute live demo specified in [`docs/plan/bfsi-v1/02-bank-demo.md`](../plan/bfsi-v1/02-bank-demo.md). Every slide traces to a pain point in [`docs/plan/bfsi-v1/01-pain-points.md`](../plan/bfsi-v1/01-pain-points.md). The compliance posture slide and the roadmap slide trace to [`docs/compliance/compliance-roadmap-v1.md`](../compliance/compliance-roadmap-v1.md).

Owner of changes: Agent #42 (CRO). + +--- + +## Slide 1: Title + +**Speaker time:** 30s +**Visual:** Centred wordmark "Replace your credential database. Keep your customers." Below: ZeroAuth logo (left) + Anchor Bank logo placeholder (right) separated by a hairline. Footer line: operator name, date, audience (CISO / CFO / CRO / CIO). +**Speaker notes:** +- Read the title verbatim — it is the entire thesis compressed. +- Name the operator + the bank executive in the room. +- Set the runtime: "22 minutes of demo, 15 of questions, you keep a one-page summary." +**Pain-point trace:** P1 (frames the deck around credential-database breach exposure). +**Required artefacts (engineering):** ZeroAuth wordmark file; partner-bank logo asset secured by Agent #48 ahead of room. +**Compliance trace:** None directly — the slide sets the frame for the §2(t) story on slide 7. +**Failure mode if cut:** The deck opens with no thesis; the room interprets the rest as a feature tour instead of a category claim. + +## Slide 2: The thesis (30 seconds) + +**Speaker time:** 30s +**Visual:** One sentence, centred, 60 pt: "We replace the database your customer credentials live in. The thing that breaches and creates DPDP §8 liability." No logo, no chrome, no chart. +**Speaker notes:** +- Read the sentence. +- Pause for two beats — let the room re-read it. +- "We do not replace your IdP. We do not replace your core banking. We replace the credential store." +**Pain-point trace:** P1 — credential-database breach exposure under DPDP §8. +**Required artefacts (engineering):** None — pure narrative. +**Compliance trace:** DPDP Act §8 (security safeguards + 72-hour breach notification) per compliance roadmap §2.1. +**Failure mode if cut:** Room mis-categorises ZeroAuth as another IdP and benchmarks us against Auth0 feature-for-feature instead of against the breach-blast-radius axis. + +## Slide 3: Pain point #1 — DPDP §8 reportable-breach exposure + +**Speaker time:** 2 min +**Visual:** Three rows of breach figures with `[VERIFY]` markers where Agent #48 has not finalised the citation yet. Row 1: ₹250 cr DPDP §33(1) penalty cap. Row 2: ₹19.5 cr IBM 2024 India sector average breach response cost [VERIFY citation]. Row 3: 4 publicly-reported 2024 BFSI breaches (StarHealth, RailYatri, HDFC Life partner, ICICI Lombard partner) [VERIFY each via Agent #48 press cite]. Right column: 40–80 % year-on-year cyber-insurance premium uplift on disclosure. +**Speaker notes:** +- "Today, the database your customer credentials live in is the largest line item of DPDP liability you carry." +- Walk the four reported breaches; do not editorialise on the named banks. +- "₹250 cr is the cap. Class action under §13 sits behind it. Your insurance premium re-rates the moment the disclosure hits." +**Pain-point trace:** P1 — direct. +**Required artefacts (engineering):** None — narrative; numbers verified by marketing before deck v1. +**Compliance trace:** Compliance roadmap §2.1 (DPDP §§8, 13, 33). +**Failure mode if cut:** The cost framing for the rest of the deck collapses; the bank does not connect "fewer columns in the database" to "DPDP liability shrinks". + +## Slide 4: Pain point #2 — Aadhaar e-KYC operational dependency + +**Speaker time:** 90s +**Visual:** Two-column comparison. Left: "Per-eKYC ₹20 × 5 M onboardings/year = ₹100 cr/year UIDAI fees". Right: "30–45 % video-KYC drop-off × 5 M attempts × ₹4,000 LTV = ₹700 cr foregone revenue/year" (Razorpay 2023 industry figure, [VERIFY]). Footer: "UIDAI service downtime last 12 months: 7 incidents > 2 hours." +**Speaker notes:** +- "Every digital onboarding journey in India hits UIDAI through a KUA/SUA. You pay ₹3–₹20 per auth. You take the 30–45 % video-KYC drop-off. You inherit UIDAI downtime." +- "We hit Aadhaar once at enrollment. Every subsequent authentication is a Groth16 proof. Zero UIDAI calls." +**Pain-point trace:** P2. +**Required artefacts (engineering):** `/v1/identity/register` endpoint (Phase 1 week 4); `DIDRegistry` on Base Sepolia (Phase 0 week 2); Android enrollment flow (Phase 1 week 6). +**Compliance trace:** Compliance roadmap §2.5 — RBI MD on KYC (periodic-refresh hook tested by Phase 2). ZeroAuth's enrollment flow anchors a SHA-256 biometric → DID + Poseidon commitment; the bank's KYC officer still owns the underlying CKYC / V-CIP record. +**Failure mode if cut:** The CFO does not see the UIDAI per-auth line item and discounts the recurring savings story on slide 11. + +## Slide 5: Pain point #3 — SMS OTP cost + SIM-swap loss + +**Speaker time:** 90s +**Visual:** Single hero number: "₹2,500 cr — FY24 industry-wide SIM-swap-enabled account-takeover loss across Indian banks [VERIFY analyst Q4-2025 brief]." Below: smaller line "+ ₹43 cr/year SMS gateway spend for a 30M-customer bank (₹0.20 × 6 OTPs/month × 12 × 30M)". Footer: "Delivery rate post-DLT regime: 88–92 % first-attempt." +**Speaker notes:** +- "SMS OTP is two failure modes at once. The gateway bill, and the SIM swap." +- "SS7 and SIM-swap bypass OTP entirely. FY24 industry loss attributable to SIM-swap-enabled ATO is roughly ₹2,500 cr." +- "Our authentication never crosses the cellular network. There is no shared cellular-bound secret in the loop." +**Pain-point trace:** P3 + P6 (the SIM-swap fraud surface). +**Required artefacts (engineering):** Android rapidsnark prover + StrongBox key wrap + BiometricPrompt path (Phase 1 weeks 6–8); `/v1/zkp/verify` endpoint (Phase 1 week 7). +**Compliance trace:** Compliance roadmap §2.4 — RBI MD on Digital Payment Security Controls §5.3 (additional auth for high-value transactions). +**Failure mode if cut:** The room frames us against MFA upgrades (push notification, TOTP) instead of against "remove SMS from the auth path entirely". + +## Slide 6: The protocol (60 seconds) + +**Speaker time:** 60s +**Visual:** Single diagram, four boxes left-to-right. Box 1: customer's Android phone (StrongBox-bound key, biometric, rapidsnark prover). Box 2: Pramaan ZK identity verification (Groth16 over BN128, circuit `identity_proof.circom` v1.2). Box 3: bank verifier endpoint (`/v1/zkp/verify`). Box 4: on-chain `DIDRegistry` + `Groth16Verifier` on Base L2. Below: "Patent IN202311041001. Live since W3 of Phase 0." +**Speaker notes:** +- "Pramaan is our ZK identity verification protocol." +- "Customer phone holds a StrongBox-bound key plus a Poseidon commitment derived from the customer's biometric. Each authentication is a Groth16 proof over `(commitment, session_nonce, tenant_id_hash)`." +- "We anchor the DID on Base L2. The bank's audit log is hash-chained and anchored on the same chain." +**Pain-point trace:** Sets up P1, P2, P3, P6 mechanism for the next two slides. +**Required artefacts (engineering):** `circuits/identity_proof.circom` v1.2 (Phase 1 week 10 trusted-setup ceremony, ADR 0015 circuit-version lock); `contracts/DIDRegistry.sol`, `contracts/Groth16Verifier.sol` (Phase 0 week 2). +**Compliance trace:** Compliance roadmap §2.1 (DPDP §2(t) treatment of commitments — counsel memo v1 due week 6, signed week 9 per D-Q1-05). +**Failure mode if cut:** Bank cannot map the rest of the deck onto a concrete mental model and frames us as a black box. + +## Slide 7: What we store + +**Visual:** Database column screenshot mockup — `users` table — with exactly four columns highlighted: `did`, `commitment`, `created_at`, `tenant_id`. Below, struck through in red: `name`, `email`, `phone`, `pan`, `aadhaar`, `face_template`, `fingerprint_template`. Footer: a single line of DPDP §2(t) text rendered verbatim. +**Speaker time:** 90s +**Speaker notes:** +- "This is the schema of our `users` table. Four columns. No name, no email, no phone, no biometric." +- "The commitment is a 32-byte field element. The DID is opaque. Together they do not enable an authentication and do not identify the data principal." +- Read DPDP §2(t) aloud. +**Pain-point trace:** P1 + P10 (DPDP §2(t) treatment + cross-border data-localisation story). +**Required artefacts (engineering):** `tests/schema-purity.test.ts` — passing on `dev` (C-003). Verified by Agent #14 dashboard "Users" view per `dashboard/src/routes/tenant/users.tsx`. +**Compliance trace:** Compliance roadmap §2.1 + D-Q1-05 (DPDP §2(t) memo, external counsel). Also §1.1 in-scope perimeter mapping. +**Failure mode if cut:** The CISO does not see the literal column list and reverts to "they say their database has fewer columns, but does it really". + +## Slide 8: Breach simulation (live in demo) + +**Speaker time:** 30s — this slide is a *handoff* to Scene 4 of the live demo, not a content slide +**Visual:** Single line, 60 pt: "Bring me your database. Show me a name." Below: 14 pt subline "Live, against the production codebase, in the next four minutes." +**Speaker notes:** +- Read the line. +- Walk to the laptop. Trigger Scene 4 of the demo per the operator runbook. +- Do not narrate over the demo — let the empty rows speak. +**Pain-point trace:** P1 (the demo moment for the credential-database breach exposure). +**Required artefacts (engineering):** Scene 4 of `02-bank-demo.md` end-to-end (Phase 1 week 11 demo-ready); seeded Anchor Bank tenant per `scripts/seed-demo-tenants.ts`; psql admin shell pre-prepared per runbook §1.4. +**Compliance trace:** Compliance roadmap §2.1 (DPDP §2(t)); §2.2 RBI MD on IT Governance §6.4 — audit logs come up two slides later. +**Failure mode if cut:** The slide deck would carry the §2(t) argument on its own, which is weaker than the live database walk. The room must *see* the empty columns; the slide alone is not enough. + +## Slide 9: Audit log — tamper-evident + +**Speaker time:** 90s +**Visual:** Two-panel diagram. Panel A: a vertical hash chain — each `audit_events` row shows `id`, `event_type`, `previous_hash`, `row_hash` arrows connecting downward. Panel B: a Basescan transaction screenshot mockup showing yesterday's `AuditAnchor.anchor(terminal_hash, day_id)` call confirmed on Base L2. Caption: "Tampering requires both rewriting the chain and invalidating an on-chain transaction." +**Speaker notes:** +- "Every row in `audit_events` references the prior row's hash. Each day's terminal hash is anchored on Base L2 at end-of-day." +- "Your own auditor can replay the chain off a database dump and match the on-chain anchor — without involving us." +- "Scene 5 will tamper with one row in front of you. The integrity check fails. The on-chain anchor still records the untampered truth." +**Pain-point trace:** P4 — privileged-access insider abuse and inadequate audit-log tamper-evidence. +**Required artefacts (engineering):** ADR 0013 (audit hash chain); ADR 0014 (on-chain anchor cadence); `src/services/audit.ts` `appendAuditEvent` (C-011 + C-013); `/api/admin/audit-integrity` endpoint (C-014). +**Compliance trace:** Compliance roadmap §2.2 — RBI MD on IT Governance §6.4 (audit logs + segregation of duties); §2.6 SOC 2 CC7.2 (system-monitoring evidence). +**Failure mode if cut:** Scene 5 of the demo runs without prior context; the CRO does not pre-load the "RBI §6.4 evidentiary compliance" framing and the demo lands as "neat trick" rather than "regulator-defensible artefact". + +## Slide 10: Compliance posture + +**Speaker time:** 2 min +**Visual:** Four-row timeline. Row 1: DPDP §2(t) legal memo — in progress with external counsel, v1 by Phase 0 week 6, signed by week 9 (D-Q1-05). Row 2: SOC 2 Type I — auditor engaged week 4, evidence period weeks 14–22, report by Phase 2 close (week 26). Row 3: SOC 2 Type II + ISO 27001 — Type II evidence weeks 27–39, ISO Stage 2 week 36, certificate week 38, Type II report week 42 (D-Q3-13, D-Q4-02). Row 4: RBI sandbox — application week 35, acceptance decision week 39 (D-Q3-15). +**Speaker notes:** +- "We are not certified today. We are on a 12-month path with named auditors, a signed counsel relationship, and a roadmap published in the repo." +- "By month 6 we are SOC 2 Type I. By month 9 we are SOC 2 Type II and ISO 27001 certified. RBI sandbox application is in by month 9." +- Reference `docs/compliance/compliance-roadmap-v1.md` — "the document is in the public repo; your compliance team can read it the same day." +**Pain-point trace:** P1, P4, P5, P10 (the compliance umbrella under which the entire offer sits). +**Required artefacts (engineering):** None — this is a forward-looking commitment slide grounded in the compliance plan. +**Compliance trace:** Compliance roadmap §2.1 DPDP, §2.6 SOC 2 Type I, §2.7 SOC 2 Type II, §2.8 ISO 27001, §2.9 RBI Regulatory Sandbox. Quarterly milestones §3 + deliverables §4 (D-Q1-05, D-Q1-07, D-Q1-08, D-Q2-10, D-Q3-13, D-Q3-15, D-Q4-02). +**Failure mode if cut:** Bank's procurement team blocks at "show us your SOC 2 report" and the conversation does not advance to pilot. + +## Slide 11: Per-auth marginal cost — from ₹0.20 to ~₹0.00 + +**Speaker time:** 90s +**Visual:** Single arithmetic line, centred. "30,000,000 customers × 6 OTPs/month × ₹0.20 = ₹43 cr/year". Below, struck-through arrow into "₹0". Footer: "Plus ₹100 cr/year in UIDAI per-eKYC fees from slide 4. Net cash line item recovered in year 1." +**Speaker notes:** +- "For a 30-million-customer bank, six OTPs per month, 20 paise per OTP, you spend ₹43 crore a year on SMS gateway. Add the UIDAI line from slide 4." +- "ZeroAuth charges a per-seat per-month fee — pricing is slide 17. The cellular-network cost goes to zero. The UIDAI line goes to one event per customer per refresh cycle." +- "18-month payback on the seat fee is the standard CFO model." +**Pain-point trace:** P3 (SMS gateway cost) + P2 (UIDAI fees). +**Required artefacts (engineering):** None — pure commercial math; references the live `/v1/zkp/verify` path that replaces the SMS OTP loop. +**Compliance trace:** None directly. The cost story is independent of certification posture. +**Failure mode if cut:** The CFO leaves the room without a payback number and the conversation ends as "interesting tech, no business case". + +## Slide 12: Replaces, does not displace + +**Speaker time:** 90s +**Visual:** Architecture stack diagram, three layers. Top layer: customer device (ZeroAuth app — Pramaan prover, StrongBox key, biometric). Middle layer: bank's existing IdP + SAML/OIDC + core banking — unchanged, with a small "ZeroAuth credential store" block carved out of where the password / OTP / mPIN database used to sit. Bottom layer: on-chain anchor on Base. Annotation: "Bank keeps SAML/OIDC. Bank keeps its IdP. ZeroAuth replaces the credential store." +**Speaker notes:** +- "We sit between your customer's device and your IdP. We do not displace your federation layer." +- "Your SAML and OIDC adapters keep working — see `src/routes/saml.ts` and `src/routes/oidc.ts`. Your downstream applications do not change." +- "We replace the credential storage table. That is the thing that breaches." +**Pain-point trace:** P1 (the credential database is the thing replaced) — operationalises the slide-2 thesis. +**Required artefacts (engineering):** `src/routes/saml.ts`, `src/routes/oidc.ts` (legacy SAML/OIDC surface); `src/middleware/tenant-auth.ts`; `src/services/api-keys.ts` (the `za_{live,test}_*` key model that brokers downstream applications). +**Compliance trace:** Compliance roadmap §1.1 in-scope perimeter; §2.2 RBI MD on IT Governance §10 (third-party risk). The "ZeroAuth verifies, doesn't store credentials" framing is the third-party-risk story. +**Failure mode if cut:** The bank's IdP team blocks the deal at "we just signed a 5-year Okta renewal, we are not replacing it". This slide explicitly tells them we do not need them to. + +## Slide 13: Comparison vs Auth0 / Okta / Ping + +**Speaker time:** 2 min +**Visual:** Five-row table, two columns. Header: "Auth0 / Okta / Ping" — "ZeroAuth". +- Row 1: Credential storage — "Hash + MFA seed in their database" / "Poseidon commitment only". +- Row 2: Breach blast radius — "Full PII exfiltration + DPDP §8 reportable" / "Field elements only; not personal data under §2(t) on counsel reading". +- Row 3: SIM-swap defence — "Push notification (re-onboard attack)" / "StrongBox-bound DID + biometric — no shared cellular secret". +- Row 4: DPDP §2(t) position — "Personal data under §2(t)" / "Cryptographic commitment, counsel-memo positioned outside §2(t)". +- Row 5: Sovereignty — "American SaaS (Salesforce / Microsoft / Cisco)" / "Indian-incorporated, India-data-resident, patent IN202311041001". +**Speaker notes:** +- Walk the table left-to-right. +- On row 4, qualify aloud: "the §2(t) position is a counsel opinion in progress; we will share the memo when signed." +- "Row 5 is not a marketing claim — our data lives in `ap-south-1` with a Hyderabad replica by Phase 4." +**Pain-point trace:** Pain-points doc §"How we sell better than Auth0 / Okta / Ping" — direct lift, condensed. +**Required artefacts (engineering):** `src/services/identity.ts` (commitment derivation); `src/services/api-keys.ts` (the `za_{live,test}_*` key model); patent IN202311041001 filing reference. +**Compliance trace:** Compliance roadmap §1.3 (data residency `ap-south-1`); §2.1 DPDP §2(t) counsel memo (D-Q1-05). +**Failure mode if cut:** Procurement asks "why not Okta" and we have no compact answer. This slide is the answer. + +## Slide 14: Live demo handoff + +**Speaker time:** 30s +**Visual:** Single line: "Five scenes, 22 minutes. Watch." Below, five small numbered tiles: 1. Enrollment. 2. Login at kiosk. 3. High-value NEFT step-up. 4. Breach simulation. 5. Audit-log integrity. +**Speaker notes:** +- Read the line. +- "Five scenes. Twenty-two minutes. We run against the live reference implementation — there is no demo bypass; `tests/proof-pairing.test.ts` asserts demo-DID rejection." +- Hand off to the live demo per `docs/operations/anchor-bank-demo-runbook.md`. +**Pain-point trace:** Sets up all five demo scenes — P1 (Scene 4), P2 (Scene 1), P3 + P6 (Scene 2), P5 + P7 (Scene 3), P4 (Scene 5). +**Required artefacts (engineering):** All Phase 1 demo-ready exit-gate items from `02-bank-demo.md` "What demo-ready means". +**Compliance trace:** None on this slide — the demo itself touches every compliance trace. +**Failure mode if cut:** The deck transitions awkwardly into the demo and the room is unsure whether to watch the laptop or the projector. + +## Slide 15: Demo recap + +**Speaker time:** 2 min +**Visual:** Five rows, three bullets each. +- Scene 1 (enrollment): one Aadhaar dip · DID + Poseidon commitment on-device · on-chain anchor confirmed on Basescan. +- Scene 2 (kiosk login): 1.0–1.5 s wall-clock · zero SMS · audit row written, hash chained. +- Scene 3 (high-value NEFT): `tx_nonce = Poseidon(amount, payee, ts)` bound in the proof · substitution attack rejected · regulator-reconstructable audit row. +- Scene 4 (breach simulation): `users` table walked live · DPDP §2(t) text read · "show me a name" — no name. +- Scene 5 (audit-log integrity): one row tampered · integrity check FAILs · on-chain anchor still pins the untampered truth. +**Speaker notes:** +- Refer to each tile briefly. The bank just watched it; you are anchoring memory, not re-explaining. +- "That is the protocol. Five scenes. The remaining six slides cover commercials and roadmap." +**Pain-point trace:** P1, P2, P3, P4, P5, P6, P7 — every pain point referenced by a demo scene reconnects here. +**Required artefacts (engineering):** All demo-scene artefacts per `02-bank-demo.md` (each scene's "Required artefacts" table). +**Compliance trace:** Compliance roadmap §2.1 (Scene 4), §2.2 §6.4 (Scene 5), §2.4 §5.3 (Scene 3), §2.5 (Scene 1). +**Failure mode if cut:** Q&A wanders; the room does not have a single visual to point at when raising follow-up questions about a specific scene. + +## Slide 16: Pilot terms + +**Speaker time:** 90s +**Visual:** Four-quadrant card. +- Top-left: "60-day pilot · no licence charge". +- Top-right: "ZeroAuth covers integration support (Agent #45 Solutions Architect)". +- Bottom-left: "Bank commits one named CISO + one integration engineer". +- Bottom-right: "After pilot — ACV pricing (slide 17), MSA template ready by Phase 1 week 13". +**Speaker notes:** +- "Pilot is 60 days, our cost. We send a solutions architect; you name one CISO contact and one integration engineer." +- "Pilot covers one customer-facing flow and one workforce flow if you want it. Acceptance criteria are in the SOW." +- "We sign a pilot LoI today and an MSA when the pilot exits." +**Pain-point trace:** None directly — this is the commercial scaffold under which P1–P10 get addressed. +**Required artefacts (engineering):** `docs/gtm/pilot-loi-template-v0.md` (Agent #42 deliverable A42-W1-Thu). +**Compliance trace:** Compliance roadmap §4 D-Q2-11 (three bank-pilot contracts signed with RBI/DPDP clauses by week 26). +**Failure mode if cut:** The CRO leaves the room without a concrete next step and the conversation does not convert into a signature. + +## Slide 17: Pricing posture + +**Speaker time:** 60s +**Visual:** A single line: "Per-seat per-month. Indicative ACV ranges by bank scale — discussed verbally." Below: a placeholder bracket "[Mid-tier private bank] [Top-5 PSB] [Tier-2 bank]" with no numbers rendered on the slide. Footer reference: "Detailed model — `docs/gtm/pricing-model-v1.md` (under counsel review)". +**Speaker notes:** +- "Pricing is per-seat per-month for the customer-credential surface and per-seat per-month for the workforce surface." +- "I will share indicative ACV ranges verbally — they differ by bank scale and by which surfaces you adopt." +- "The full pricing model is `docs/gtm/pricing-model-v1.md` in our repo; we share it once the MNDA is signed." +**Pain-point trace:** P3 (the SMS gateway saving on slide 11 sizes against this seat fee). +**Required artefacts (engineering):** None — commercial document referenced by path. +**Compliance trace:** None directly. +**Failure mode if cut:** CFO asks "what does it cost" and we ad-lib without a structured response. + +## Slide 18: Roadmap + +**Speaker time:** 90s +**Visual:** Four phase tiles laid out left-to-right. +- Phase 1 (months 1–3) — demo-ready · 3 design-partner LoIs · DPDP §2(t) memo signed · ADR 0011/0013/0014/0015 landed. +- Phase 2 (months 4–6) — pilots live · SOC 2 Type I report (D-Q2-10) · ISO Stage 1 (D-Q2-06) · contract audit (D-Q2-08). +- Phase 3 (months 7–9) — SOC 2 Type II evidence (D-Q3-02) · ISO Stage 2 + certificate (D-Q3-13) · RBI sandbox application submitted (D-Q3-06). +- Phase 4 (months 10–12) — mainnet contract deployment (D-Q4-04) · HSM signer migration (D-Q4-06) · first paid bank in production (D-Q4-08). +**Speaker notes:** +- "Twelve months.

Computes the per-tenant terminal hash for the target UTC day, encodes a recordAnchor(bytes32, uint64, bytes32, uint64) call against contracts/AuditAnchor.sol (C-016, d6c6a4e), and stages the {to, data, value: 0} transaction in the report the signer worker will broadcast. The signer half is intentionally NOT in this commit. Base Sepolia keys do not live inside the API container; the broadcaster reads the staged report from a CronCreate-managed worker that holds the wallet key. This split lets us land the computation + schema now and ship the signer with the deploy keys later. What this commit adds: - src/services/anchor-job.ts computeDailyAnchorPayload(tenantId, env, dayUtc): null when the window is empty, else {tenantId, tenantIdHash, dayUtc, terminalHash, rowCountAtAnchor}. Query uses ROW_NUMBER over audit_events ORDER BY id DESC to pick the chain head as of midnight-the-next-day, and IS NOT DISTINCT FROM so null-env tenants are matched. dayUtcAsYYYYMMDD encodes the day as a uint64 matching the contract. runDailyAnchorJob(dayUtc?): defaults to yesterday-UTC (the 24h block that closed at 19:00 UTC = 00:30 IST per ADR 0014). Enumerates active tenants, sweeps {live, test}, skips empty windows and already-anchored keys, encodes recordAnchor call data via ethers.Interface, and emits one audit.anchor.staged self-audit row per staged tenant so the anchor process is itself in the chain it just summarised (next day's anchor picks it up — recursive 'anchor ran on this day' property). Per-tenant errors land in report.errors instead of throwing so one RPC blip can't blackhole the rest of the sweep. - src/services/db.ts New audit_anchors table per ADR 0014: (tenant_id, environment, day_utc, terminal_hash, row_count, tx_hash, block_number, anchored_at) with UNIQUE (tenant_id, environment, day_utc) mirroring the on-chain write-once flag. tx_hash and block_number stay NULL until the signer broadcasts. - tests/anchor-job.test.ts Eight tests, no live Postgres or RPC. Mocks getPool + appendAuditEvent via jest.mock per the platform.test.ts pattern. Covers: empty window, single-row, multi-row last- hash-wins, full-tenant scan, zero-event skip, already- anchored skip, recordAnchor data round-trip via ethers.Interface.decodeFunctionData, and the self-audit row shape (actor_type=system, actor_id=anchor-job, action= audit.anchor.staged, metadata carrying day_utc / row_count / terminal_hash / tx_data). - tests/schema-purity.test.ts audit_anchors added to KNOWN_TABLES and TENANT_SCOPED_TABLES, plus an explicit column-allowlist test pinning the nine columns ADR 0014 specifies. No dependency additions: ethers 6.16 is already in package.json.

The existing in-memory limiters in src/middleware/tenant-auth.ts and the express-rate-limit instance wired in src/app.ts only protect a single process; once we scale the API horizontally behind a load balancer, an attacker who hashes their requests across replicas defeats the in-memory counters. This commit adds a sliding-window rate-limit middleware that backs its counters in Postgres so every replica sees the same window. Schema (src/services/db.ts): - New table rate_limit_buckets with PK on bucket_key (composite string of route + identity + window-start floor), atomic INSERT … ON CONFLICT … DO UPDATE … RETURNING count gives the post-increment value in a single round-trip. - Intentionally NOT (tenant_id, environment)-scoped because the /api/console/login bucket exists before any tenant is resolved. This is the first table in the schema to opt out of that convention — the rationale is captured in the schema-purity test and in an inline schema comment. Middleware (src/middleware/rate-limit.ts): - pgRateLimit({ route, windowMs, max, keyBy }) factory; keyBy is 'apiKey' (requires authenticateTenantApiKey to run first), 'ip', or 'apiKey+ip'. - 429 response: { error: 'rate_limited', message: '…', retry_after_seconds } plus Retry-After header per RFC 7231. - X-RateLimit-Limit, -Remaining, -Reset headers set on every request whether 429 or pass-through. - cleanupRateLimitBuckets() DELETEs expired rows; called from a 60 s setInterval kicked off by initRateLimitCleanup() in src/server.ts (unref'd so it doesn't keep the loop alive through graceful shutdown). - Fail-open on Postgres outage — rate-limit is a hardening layer, not an auth layer; a transient DB hiccup should not page out /api/console/login. Wiring: - POST /v1/auth/zkp/verify — 30 req / 60 s per apiKey - POST /v1/auth/zkp/register — 30 req / 60 s per apiKey - POST /api/console/login — 10 req / 60 s per ip (on top of the existing in-memory authLimiter) Tests: - tests/rate-limit.test.ts (9 tests): pass-through under cap, pass-through at boundary, 429 over cap, Retry-After header, bucket key shape for keyBy=apiKey, bucket key shape for keyBy=ip, cleanup DELETE statement, plus two buildBucketKey sanity assertions on the window-floor math. - tests/schema-purity.test.ts: rate_limit_buckets column allowlist + biometric-name guard + KNOWN_TABLES enrollment.

Captures the 10 baseline commercial, operational, regulatory, strategic, security, and financial risks that the founder, CCO, CRO, and Risk & Audit lead carry on their dashboards. Distinct from docs/threat_model.md, which holds the technical attack catalogue (A-NN rows). Each enterprise risk references the threat-model rows it relates to so the two documents stay bidirectionally linked per the §6.5 operating principle. Document deliverable A40-W1-Mon from docs/plan/bfsi-v1/agents/agent-40-risk-audit.md. Pairs with the compliance roadmap at docs/compliance/compliance-roadmap-v1.md whose §7 holds the thinner compliance-bearing subset; this register is the authoritative copy. References docs/threat_model.md throughout (A-02, A-07, A-09, A-10, A-13, A-17, A-21, A-22, A-28) and docs/cryptography/trusted-setup-ceremony.md (R-ENT-04, R-ENT-07) and docs/compliance/privacy/data-inventory-v1.md (R-ENT-03 scoping). Risks classified by likelihood (1..5) x impact (1..5) with appetite bands accept <= 6, review 7-12, reject >= 13. At v1 all residuals sit in the auto-accept band after mitigation. Cadence is weekly walk by Agent #40, monthly review with Agent #1 + #36 + #42 on the 15th, quarterly board review in the last week of each Q, plus event-driven triggers per §6.3. Sign-offs in §7. [no-test] markdown-only documentation deliverable. Next review 2026-06-01 per A40-W2-Mon ticket which updates the register with commit hashes for closed mitigations. --- .../risk/enterprise-risk-register-v1.md | 506 ++++++++++++++++++ 1 file changed, 506 insertions(+) create mode 100644 docs/compliance/risk/enterprise-risk-register-v1.md diff --git a/docs/compliance/risk/enterprise-risk-register-v1.md b/docs/compliance/risk/enterprise-risk-register-v1.md new file mode 100644 index 0000000..8956676 --- /dev/null +++ b/docs/compliance/risk/enterprise-risk-register-v1.md @@ -0,0 +1,506 @@ +# Enterprise risk register — v1 + +**Status:** v1 — first issue, baseline of 10 enterprise risks. +**Owner:** Agent #40 (Risk & Audit Lead). +**Reviewer:** Agent #36 (Chief Compliance Officer). +**Sign-off authority for residual >= 13:** Agent #1 (founder / CTO) plus +Agent #28 (founder / product, in his Pulkit-Amit founder role on the +roadmap).

Purpose + +This register is the **enterprise-level** view of the risks ZeroAuth +faces as a going concern: commercial, operational, regulatory, strategic +and high-blast-radius security risks that would degrade the company's +ability to deliver the BFSI v1 roadmap or to sustain a customer base +once delivered. It is **distinct** from +[docs/threat_model.md](../../threat_model.md), which is the technical +attack catalogue (`A-NN` rows) tracking spoofing, replay, tampering, +elevation-of-privilege and similar attack vectors at the protocol layer. + +The two documents are linked: technical attacks **ladder up** to +enterprise risks. A successful replay of a captured proof (A-02) does +not in itself sink the company, but a pattern of unmitigated A-02 +incidents materialises R-ENT-02 (supply-chain) and R-ENT-03 (DPDP §8 +breach) depending on root cause. Each enterprise risk row therefore +references the threat-model `A-NN` entries that contribute to it. + +**What changed since the threat model:** the threat model is exhaustive +at the attack-vector level — every endpoint, every payload field, every +write surface. This register is exhaustive at the **enterprise** level — +the risks that the founder, the CCO, the CRO and the board carry on +their dashboard. Threat model has many rows; the register has ten. + +**Audience:** Agent #1 (founder/CTO), Agent #28 (founder/product), Agent +#36 (CCO), Agent #42 (CRO), Agent #40 (Risk & Audit), and the regulator +or auditor reading our governance evidence pack. + +**Cadence:** see §4. Re-assessment is event-driven (see §6 operating +principles) on top of the calendar cadence. + +--- + +## 2. Risk classification + +The classification grid is the same across enterprise risks and the +technical threat-model rows that ladder up to them, so a single language +holds end to end. + +### 2.1 Likelihood (L) + +| Score | Label | Plain-English meaning | +|---|---|---| +| 1 | rare | Expected once in 10 years or longer. No precedent in the team's experience. | +| 2 | unlikely | Expected once in 3–10 years. Has happened to peer companies but not to us. | +| 3 | possible | Expected once in 1–3 years. Has happened in adjacent industries or in early demos. | +| 4 | likely | Expected at least once in the next 12 months. Active controls keep it from being routine. | +| 5 | almost-certain | Expected multiple times in 12 months unless a hard mitigation lands. | + +### 2.2 Impact (I) + +| Score | Label | Plain-English meaning | +|---|---|---| +| 1 | insignificant | Local inconvenience; absorbed by existing on-call rotation in under a day. | +| 2 | minor | A sprint of remediation work; no customer-visible degradation beyond a hours-scale outage. | +| 3 | moderate | A pilot bank pauses; one quarterly milestone slips by up to 4 weeks. No regulator notification. | +| 4 | major | A signed pilot terminates, or a Phase exit gate slips by 8+ weeks, or a regulator opens correspondence. | +| 5 | catastrophic | Existential — the company is unable to operate as a BFSI vendor; or DPDP §8 breach with > 10 000 data principals affected; or RBI notice; or founder dismissal. | + +### 2.3 Inherent risk (L × I) + +The product `L × I` is the **inherent** risk score, computed before any +mitigation is applied. Range 1..25. + +### 2.4 Residual risk (L_residual × I_residual) + +After mitigations land, both likelihood and impact may drop. The +**residual** risk is computed against the after-mitigation values. The +target for v1 is that every residual sits in the low-amber band (<= 6) +or has explicit sign-off from Agent #1 + Agent #28. + +### 2.5 Risk appetite + +| Residual band | Verdict | Action | +|---|---|---| +| 1–6 | low-amber | Auto-accept.

Reviewed monthly. | +| 13–25 | red | Hard-stop. No new pilot signed, no new release shipped, until either residual drops below 13 or the founders explicitly sign off (Agent #1 + Agent #28) with a documented mitigation timeline. | + +The threshold lines are deliberately tight: a 4×4=16 inherent that drops +to 3×2=6 residual is acceptable; a 4×4=16 that drops only to 3×4=12 is +mid-amber and gets monthly attention. + +--- + +## 3.

A single regulatory shift (RBI tightening third-party-vendor governance), a single market-wide downturn (CRR change starving bank IT budgets), or a single competitive entrant (a domestic incumbent bundles identity verification into a core banking suite) materially degrades the company's commercial trajectory. Healthcare and Web3 are deferred to Phase 2+, so for ~26 weeks ZeroAuth has no diversification cushion. | +| **Inherent L × I** | 4 × 4 = **16** | +| **Mitigations** | (1) Horizontal expansion to healthcare in Phase 2 (compliance-roadmap-v1 §3.3 Q3 milestones name the second-vertical demo). (2) GCC pilot scoping in Phase 4 — see compliance-roadmap-v1 §3.4 Q4 placeholder. (3) Target recurring-revenue mix > 80 % so loss of any single bank does not terminate the company (KPI tracked by Agent #42). (4) Identify two cohorts in flight at the RBI sandbox (R-COMP-05 mitigation in compliance roadmap) so we keep an open regulator door.

Indirectly, A-09 (console JWT theft) and A-13 (session fixation in pairing) magnify the impact if they coincide with a single-bank concentration event. | +| **Residual sign-off** | Agent #42 (auto-accept at residual 6). | + +### R-ENT-02 — Supply-chain attack via npm / Gradle / cargo dependency + +| Field | Value | +|---|---| +| **Class** | Security | +| **Description** | A direct or transitive dependency in `package.json`, `mobile/build.gradle`, the IoT firmware Cargo crates, the Hardhat contract deps, or the snarkjs/circomlib chain is compromised. The compromise injects code that exfiltrates the `BLOCKCHAIN_PRIVATE_KEY`, the `JWT_SECRET`, the API-key plaintext seen at issuance, or the `biometricSecret` in the prover. Same class as `event-stream`, `ua-parser-js`, `xz-utils` 2024 backdoor. | +| **Inherent L × I** | 3 × 4 = **12** | +| **Mitigations** | (1) Nightly CVE monitor running in CI (commit `f8a756c` on `.github/workflows/cve-monitor.yml`) with high-severity alerts routed to the on-call channel — verifiable by inspecting the workflow run history. (2) dep-add ADR-first policy (CLAUDE.md §6 + ADR `/adr/0000-grandfather-initial-deps.md` baseline) plus `scripts/check-dep-trail.sh` blocking merge when a dep lacks an ADR — verifiable by triggering a no-ADR PR and asserting CI fails. (3) Signed-only releases on Phase 3 SBOM (compliance-roadmap-v1 §3.3 Q3 milestones) — verifiable by checking `provenance: true` on the GitHub Actions release attestation when Phase 3 work completes. (4) Lockfile review gate in CI — `package-lock.json` diffs > 100 lines are routed for human review; verifiable by a dependent PR that exceeds the threshold. (5) WebView snarkjs bundling with SHA-256 pinning per [ADR 0010](../../../adr/0010-android-webview-snarkjs-bundling.md) closes the runtime-CDN class of supply-chain attack on the prover (A-17). | +| **Residual L × I** | 2 × 3 = **6** | +| **Owner** | Agent #26 (Application Security Engineer).

A breach of bank-onboarded user records, a misrouted audit-event export, or a leaked Postgres backup falls in this class. Penalties under §33 can reach INR 250 crore per incident. | +| **Inherent L × I** | 3 × 5 = **15** | +| **Mitigations** | (1) DPO breach-notification SOP in [docs/compliance/dpdp/breach-notification-sop-v0.md](../dpdp/breach-notification-sop-v0.md) (planned A37-W?? deliverable per agent-37 plan; v0 lives by Phase 0 exit). Verifiable by quarterly tabletop (first tabletop Q3 wk 33 per compliance-roadmap-v1 §3.3). (2) Hash-chained audit log (commit `a475ed8` on `src/services/audit.ts`, per [ADR 0013](../../../adr/0013-audit-log-hash-chain.md)) gives a cryptographic record of every write surface, supporting forensics within the 72-hour window. Verifiable by replay via `/api/admin/audit-integrity`. (3) Per-tenant on-chain anchors per [ADR 0014](../../../adr/0014-on-chain-anchor-cadence.md) make the audit chain externally verifiable, so a regulator can confirm scope without trusting any ZeroAuth process. (4) [DPDP §2(t) commitments memo v0](../dpdp-2t-commitments-memo-v0.md) argues that the Poseidon commitment and DID are not personal data, limiting the *reportable surface area* to the genuine PII (email, tenant company name, lead form fields per data-inventory-v1 §3.1, §3.2). (5) Data inventory v1 explicitly classifies every data element so the breach scoping in the 72-hour window is a lookup, not a derivation. | +| **Residual L × I** | 2 × 3 = **6** | +| **Owner** | Agent #37 (Compliance / DPDP & RBI Lead). Co-owners: Agent #36 (CCO) for the regulator interface and Agent #41 (DPO) for the principal-side notifications. | +| **Review cadence** | Monthly.

If every contributor colludes — or the coordinator runs a solo setup and the team accepts the artefact uninspected — the toxic waste is recoverable and the holder can forge accepted proofs against any tenant's commitments indefinitely. Until detected this destroys the verification guarantee at the heart of the product. | +| **Inherent L × I** | 2 × 5 = **10** | +| **Mitigations** | (1) Six (>= 6) contributors with the at-least-one-honest assumption (trusted-setup-ceremony.md §1.4 + §2.2). Verifiable by inspecting the contributor list in `docs/team/crypto/trusted-setup-contributors.md` and the chained transcripts in `circuits/ceremony-transcripts/v1.2/`. (2) External attestor: an external cryptographer (not on ZeroAuth payroll and not from any contributor's employer) re-verifies offline post-ceremony and publishes a PGP-signed `attestation.pdf`. Verifiable by checking the PGP signature in the published transcript bundle. (3) Public transcripts: every contribution hash and the final beacon round are published with sources; any third party can replay-verify. (4) The on-chain `Groth16Verifier` is the verifiable artefact — its bytecode is on Base Sepolia (Phase 0–3) and Base mainnet (Phase 4) and is checked against the local artefact via bytecode-equivalence verification on deploy (R-ENT-08 mitigation #4). (5) Selection rules (>= 2 external, no shared employer, no shared laptop+OS combo) reduce the realistic collusion surface. | +| **Residual L × I** | 1 × 4 = **4** | +| **Owner** | Agent #11 (Senior Cryptography Engineer — circuit + prover, coordinator).

Quarterly between ceremonies. | +| **Last reviewed** | 2026-05-28 (v1 issue). | +| **Threat-model rows** | None directly today — the threat model treats proof verification (A-02), not key-genesis. A new `A-NN` entry "forged proof via setup compromise" is queued for the threat-model bump that lands with the v1.2 circuit. | +| **Residual sign-off** | Agent #11 (auto-accept at residual 4). | + +### R-ENT-05 — Vendor lock-in / lapse + +| Field | Value | +|---|---| +| **Class** | Operational | +| **Description** | ZeroAuth depends on a small set of external SaaS vendors: GitHub Enterprise Cloud (code + CI), Sentry (error reporting, scrubbed), Cloudflare (TLS termination on marketing site), 1Password (secrets), Google Workspace (SSO + corporate IT), the eventual evidence collector (Drata / Vanta / Sprinto), the eventual bug bounty platform (HackerOne / BugCrowd), and the eventual HSM vendor (Phase 4). A unilateral price hike, an account suspension, an export-control change, or a vendor going dark each interrupts compliance evidence collection, deploy ability, or breach-response readiness. | +| **Inherent L × I** | 3 × 3 = **9** | +| **Mitigations** | (1) Annual vendor review owned by Agent #50 (Operations) per the agent-50 plan; recorded in `docs/compliance/vendors/<vendor>/annual-review-<year>.md`. Verifiable by inspecting the directory. (2) DPA on file per vendor — see compliance-roadmap-v1 §1.3 ("each covered by a DPA on file"). Verifiable by checking the off-repo evidence pack hash reference in `docs/compliance/evidence-pack/<year>-<q>/`. (3) RBI Phase-3 outsourcing-policy alignment — RBI MD on IT Governance §10 (third-party risk) requires the bank to inspect our vendor management; the inspection-readiness checklist (compliance-roadmap-v1 §2.2) captures the cross-reference. (4) Reserve fund earmarked by Agent #50 covers replacement procurement up to 90 days of operating costs. Verifiable in the budget tracker. (5) Pre-evaluated in-country alternatives for each cross-border processor (compliance-roadmap-v1 §7.8 R-COMP-08 mitigation: `docs/compliance/dpdp/cross-border-fallbacks.md`) so a DPDP §13 tightening or a vendor lapse triggers a documented swap-out rather than improvisation. | +| **Residual L × I** | 2 × 2 = **4** | +| **Owner** | Agent #50 (Operations / Office Manager). Co-owners: Agent #36 (CCO) for DPA compliance and Agent #21 (DevOps/SRE) for CI/CD-bearing vendors. | +| **Review cadence** | Quarterly vendor review (Q2 wk 26, Q3 wk 39, Q4 wk 52 per compliance-roadmap-v1 §4). | +| **Last reviewed** | 2026-05-28 (v1 issue). | +| **Threat-model rows** | None directly. Adjacent: A-17 (WebView snarkjs supply-chain) treats the vendor risk for a specific runtime artefact. | +| **Residual sign-off** | Agent #50 (auto-accept at residual 4). | + +### R-ENT-06 — Key person dependency + +| Field | Value | +|---|---| +| **Class** | Strategic | +| **Description** | A small team (50 agents per docs/plan/bfsi-v1/03-team.md, with several "of-one" roles) means several functions have a single named owner. If Agent #1 (founder/CTO), Agent #11 (lead cryptography), Agent #12 (key management), Agent #25 (lead smart-contract engineer) or Agent #36 (CCO) leaves, falls ill, or otherwise becomes unavailable for > 2 weeks, the corresponding work stream stalls. The cryptographic and on-chain functions are especially exposed because the knowledge density is high and the load-bearing decisions live in their heads. | +| **Inherent L × I** | 3 × 4 = **12** | +| **Mitigations** | (1) Every load-bearing role has a documented secondary owner per `docs/plan/bfsi-v1/03-team.md` — secondaries listed explicitly in the role rows. Verifiable by grepping `Secondary:` in `03-team.md`. (2) ADR-driven architecture: every load-bearing decision is captured in `/adr/` so reconstructing the rationale does not require the original author (see ADRs 0009..0016 for the Phase 0 + 1 hot path). Verifiable by reading any ADR cold. (3) Key-management practices that do not depend on a single human — Phase 3 HSM-backed signer (compliance-roadmap-v1 §3.4 Q4 wk 48 D-Q4-06) replaces the BLOCKCHAIN_PRIVATE_KEY-in-`.env` posture so contract ownership rotation is procedural, not heroic. Verifiable by inspecting the HSM cutover runbook and the on-chain owner change. (4) Cross-training: every agent's secondary attends the primary's standup once per sprint; recorded in `docs/team/cross-training-log.md`. (5) Founders carry duplicate signing authority on contracts and on regulator filings, so neither founder is a single point of failure on the legal surface. | +| **Residual L × I** | 2 × 3 = **6** | +| **Owner** | Agent #1 (founder / CTO). Co-owners: Agent #36 (CCO) for governance and Agent #50 (Operations) for HR continuity. | +| **Review cadence** | Quarterly. Re-assessed within 7 days of any agent moving role or leaving. | +| **Last reviewed** | 2026-05-28 (v1 issue). | +| **Threat-model rows** | None directly. Adjacent: A-07 (leaked deployer wallet private key) becomes harder to mitigate when the named key holder is unavailable. | +| **Residual sign-off** | Agent #1 (auto-accept at residual 6). | + +### R-ENT-07 — Ceremony / circuit-version slip + +| Field | Value | +|---|---| +| **Class** | Operational | +| **Description** | The Phase 2 trusted-setup ceremony is on the critical path for the Anchor Bank demo (Phase 1 exit, wk 12) and for ISO 27001 Annex A.5.31 evidence (ISO Stage 2, wk 36). A ceremony slip — coordinator unavailable, contributor pool incomplete, ptau file integrity check failure — propagates downstream. A v1.2 → v1.3 circuit bump mid-pilot would compound the slip with a re-issuance of every tenant's pinned verification key. | +| **Inherent L × I** | 3 × 3 = **9** | +| **Mitigations** | (1) Trusted-setup runbook ([docs/cryptography/trusted-setup-ceremony.md](../../cryptography/trusted-setup-ceremony.md)) is the operational playbook; verifiable by walking section §1..§8 and asserting each artefact exists when the ceremony day arrives. (2) Phase 1 sprint-4 buffer for the ceremony: ceremony target is wk 10, ISO Stage 2 is wk 36, so 26 weeks of contingency (compliance-roadmap-v1 §7.3 R-COMP-03). (3) `cryptographer-reviewer` subagent gate per [ADR 0015](../../../adr/0015-circuit-version-pinning.md) ensures every circuit-version bump goes through plan mode + ADR + subagent review. Verifiable by inspecting the ADR-trail script's coverage of `circuits/` changes. (4) Rollback path retained: the prior verification key + pinned ptau hash kept in `circuits/legacy/<prev-version>/`; verifier service can be pinned to a prior version per ADR 0015 §3 "Rollback procedure." (5) Pre-coordinated calendar slot with the lead ISO auditor so the ceremony is on her calendar (compliance-roadmap-v1 §7.3). | +| **Residual L × I** | 2 × 2 = **4** | +| **Owner** | Agent #11 (Cryptography). Co-owners: Agent #36 (CCO) for the regulator-facing knock-on and Agent #40 (Risk & Audit) for the schedule-buffer enforcement. | +| **Review cadence** | Monthly through Phase 1 (sprints 1–4); per ceremony thereafter. | +| **Last reviewed** | 2026-05-28 (v1 issue). | +| **Threat-model rows** | Indirect: a slip that pushes the ceremony past ISO Stage 2 reduces the assurance level for A-21 (audit-log tampering) and A-02 (proof replay) where the audit defence depends on the post-ceremony verifier going live. | +| **Residual sign-off** | Agent #11 (auto-accept at residual 4). | + +### R-ENT-08 — Contract / smart-contract bug post-deployment + +| Field | Value | +|---|---| +| **Class** | Security / Financial | +| **Description** | The `DIDRegistry`, `Groth16Verifier`, and `AuditAnchor` Solidity contracts are deployed to Base Sepolia (Phase 0–3) and Base mainnet (Phase 4). A logic bug in `registerIdentity`, `revokeIdentity`, or the audit-anchor `commit` path could (a) allow forged identity rows, (b) lock out a tenant from its own anchors, or (c) silently drift the anchored hash from the off-chain truth. Once mainnet is reached, contract upgrade paths are constrained (no proxy by deliberate choice per ADR 0014), so remediation requires a new deployment + migration. | +| **Inherent L × I** | 2 × 5 = **10** | +| **Mitigations** | (1) Hardhat test suite per contract — `tests/` under `contracts/test/` covers every public function with unit + scenario tests; verifiable by `npx hardhat test` returning green. (2) Trail of Bits (or equivalent firm) external audit before mainnet — compliance-roadmap-v1 §3.3 Q3 wk 16–24 with final report by wk 24, remediation by wk 30. Verifiable by checking the published audit report under `docs/security/contract-audits/`. (3) Write-once + role-gated state changes: contract storage variables for identity registry rows are `private` + write-only-by-owner; reads are `view`; no contract method permits mass deletion. Verifiable by running slither / mythril on the bytecode. (4) Bytecode-equivalence verification post-deploy: deploy script computes the local hash of the compiled bytecode and compares against `eth_getCode(contractAddress)`; deploy fails on mismatch. Verifiable by inspecting the deploy log. (5) The cryptographer-reviewer subagent is mandatory for any change under `contracts/` (CLAUDE.md §5). | +| **Residual L × I** | 2 × 3 = **6** | +| **Owner** | Agent #25 (Senior Smart-Contract Engineer). Co-owners: Agent #26 (Application Security Engineer) for the third-party audit relationship and Agent #36 (CCO) for the change-in-scope memo to the SOC 2 + ISO auditors when mainnet lands (compliance-roadmap-v1 §3.4 Q4 wk 46 D-Q4-04). | +| **Review cadence** | Monthly during Phase 2 (audit period); on every deploy thereafter. | +| **Last reviewed** | 2026-05-28 (v1 issue). | +| **Threat-model rows** | A-07 (leaked deployer wallet key) is the operational sibling. A new `A-NN` entry "contract-storage corruption via owner-only function bug" is queued for the threat-model update that lands with the mainnet deployment. | +| **Residual sign-off** | Agent #25 (auto-accept at residual 6). | + +### R-ENT-09 — On-chain anchor disruption (Base L2 outage / gas spike) + +| Field | Value | +|---|---| +| **Class** | Operational | +| **Description** | The daily on-chain anchor of the audit-chain head ([ADR 0014](../../../adr/0014-on-chain-anchor-cadence.md)) requires a working Base L2 RPC endpoint and reasonably low gas. A Base outage (sequencer downtime, RPC provider DDoS), a gas-price spike above the configured ceiling, or a wallet-balance shortage interrupts anchor delivery. While the off-chain hash chain remains intact, the bank's auditor sees an "anchor-lagged" tenant state in the dashboard and may flag it during inspection. | +| **Inherent L × I** | 3 × 3 = **9** | +| **Mitigations** | (1) Three redundant Base RPC providers per [ADR 0014](../../../adr/0014-on-chain-anchor-cadence.md) — Alchemy, Infura, Coinbase (or current equivalents). Failover order is configured; verifiable by inducing a 503 on the primary and asserting the secondary fires. (2) Retry-with-backoff in the anchor cron (`src/services/blockchain.ts`) — up to 6 retries over 4 hours; verifiable by integration test. (3) The off-chain hash chain remains intact regardless of anchor delivery — every audit row carries `previous_hash` + `event_hash`; the chain is replay-verifiable via `/api/admin/audit-integrity` even when the on-chain anchor is days stale. (4) An "anchor-degraded" tenant state in the dashboard, surfaced via `IntegrityCheckCard` and `/api/admin/audit-integrity` ([ADR 0013](../../../adr/0013-audit-log-hash-chain.md), commits `a475ed8` and follow-ups). The state is transparent to the bank's auditor — a degraded badge with a "stale since" timestamp, not a hidden failure. (5) Gas-ceiling alerting: if the next anchor would exceed the configured ceiling (default 5 gwei), the cron emits a `pricing_breach` audit event and pages on-call rather than firing the transaction blindly. | +| **Residual L × I** | 2 × 2 = **4** | +| **Owner** | Agent #25 (Smart-Contract Engineer) for the on-chain path. Co-owners: Agent #21 (DevOps/SRE) for the RPC redundancy and Agent #40 (Risk & Audit) for the SLA. | +| **Review cadence** | Monthly. Per-incident review on any 24-hour-or-longer anchor lag. | +| **Last reviewed** | 2026-05-28 (v1 issue). | +| **Threat-model rows** | A-21 (audit-log tampering) — the on-chain anchor is one of the five mitigations on A-21, so anchor disruption raises the residual on A-21 until the anchor catches up. | +| **Residual sign-off** | Agent #25 (auto-accept at residual 4). | + +### R-ENT-10 — Anti-money-laundering / sanctions-listed enrolment + +| Field | Value | +|---|---| +| **Class** | Regulatory | +| **Description** | A bank tenant enrols an end user who is on a sanctions list (OFAC, UN, MEA) or a money-laundering watch list, and the verification event flows through ZeroAuth's pipeline. The regulator's inspection treats ZeroAuth's role as either (a) a passive infrastructure provider — the bank's responsibility — or (b) a participant in the chain — ZeroAuth's responsibility. Misclassification of role under DPDP §6 or RBI MD on KYC §44 carries direct penalties and reputational damage with all other bank prospects. | +| **Inherent L × I** | 2 × 5 = **10** | +| **Mitigations** | (1) KYC anchor at enrolment per the bank's existing screening: ZeroAuth's enrolment record references the bank's CKYC / V-CIP record ID (RBI MD on KYC §16, §44 per compliance-roadmap-v1 §2.5). Verifiable by the per-tenant attestation clause in the pilot SOW. (2) **ZeroAuth does NOT do AML** — the AML responsibility stays with the bank. ZeroAuth provides the verification artefact (proof + Poseidon commitment + audit row) and the integrity guarantee, not the watchlist check. The role boundary is documented in [docs/compliance/aml-statement.md](../aml-statement.md) (planned Agent #37 deliverable in Q1; placeholder file referenced here and slot-cited in agent-37's ticket list). Verifiable by checking the existence of the document and the per-tenant DPA clause that incorporates it by reference. (3) The aml-statement.md explicitly disclaims ZeroAuth's involvement and binds the bank to perform its own AML screening before invoking ZeroAuth's verification flow. (4) Sanctioned-jurisdiction tenant config blocks origin countries: `tenants.security_policy.jurisdiction_allowlist` enforces a per-tenant allowlist evaluated on the `clientMeta.requesterCountry` header at `/v1/proof-pairing/sessions` and `/v1/zkp/verify`. Verifiable by integration test against a known-blocked country code. (5) Audit row on every enrolment captures the bank's CKYC reference ID (when supplied), so the inspection trail traces every ZeroAuth verification back to a bank-owned KYC record. | +| **Residual L × I** | 1 × 4 = **4** | +| **Owner** | Agent #37 (DPDP & RBI Lead). Co-owners: Agent #36 (CCO) for regulator interface and Agent #41 (DPO) for principal-side communications. | +| **Review cadence** | Per pilot SOW signing and per RBI MD on KYC revision. Monthly otherwise. | +| **Last reviewed** | 2026-05-28 (v1 issue). | +| **Threat-model rows** | A-22 (PII in pairing logs) — leakage of an enrolment with a watchlist reference materialises the regulatory class-of-harm at the protocol layer. | +| **Residual sign-off** | Agent #37 (auto-accept at residual 4). | + +--- + +## 4. Risk-management cadence + +The cadence below is the floor; event triggers in §6 force interim +reviews above and beyond the calendar. + +### 4.1 Weekly — Agent #40 risk-walk + +Every Monday Agent #40 (Risk & Audit Lead) walks the register row by +row, looking for: + +- Mitigations that have become testable since last walk — i.e., a commit + has landed that closes a previously-aspirational mitigation.

Attendees: + +- Founders (Agent #1 + Agent #28). +- Agent #36 (CCO). +- Agent #42 (CRO). +- Agent #40 (Risk & Audit) — secretary. +- The board observer (when one is seated). + +Agenda: + +1. Quarterly retrospective of risks materialised vs. forecast. +2. Re-score every risk against the past quarter's facts. +3. Approve any residual >= 13 sign-off requests. +4. Decide any escalations to v2 of the register (new risks, new + classes). + +Output: board-pack row published as part of the compliance retro +(compliance-roadmap-v1 §8.1). + +### 4.4 Release-time — "risk-delta" check + +Every release-shepherd-led release runs a "risk-delta" check: + +- Any new risk surfaced by the release? Documented in the release + notes under a "Risk delta" heading. +- Any mitigation that has regressed (test removed, config flipped) on + any row of the register? Block the release until either restored or + Agent #40 + Agent #36 sign off. + +Verifiable by inspecting the release notes — the "Risk delta" heading +must be present even if its body is "none." + +### 4.5 Regulator inspection — interim review + +Every regulator inspection (DPB §17 update, RBI sandbox progress +report, a bank's internal audit walk-through, a SOC 2 auditor +fieldwork day) triggers an interim review of the relevant slice of +the register the day before the inspection. The review confirms the +"Last reviewed" column is current and that no residual has drifted +since the last weekly walk. + +--- + +## 5. Risk-acceptance protocol + +The acceptance bands from §2.5 map to acceptance procedure: + +### 5.1 Residual <= 6 (low-amber): auto-accept + +Recorded in this register with the named sign-off in the row. +Reviewed at the cadence in §4. + +### 5.2 Residual 7–12 (mid-amber): formal review + +Review required by Agent #36 (CCO) plus Agent #1 (CTO). The review +record is committed to +`docs/compliance/risk/acceptances/<R-ENT-NN>-<yyyy-mm-dd>.md` with +the following fields: + +- Risk ID + title. +- Date of review. +- Reviewers (Agent #36, Agent #1, and any subject-matter expert + pulled in). +- Mitigation roadmap (commits to land, target weeks). +- Re-review date (default 30 days; sooner if mitigations are landing + fast). +- Sign-off signatures (in the form `Agent #36: accept`). + +Mid-amber risks are reviewed monthly per §4.2 until they drop to +low-amber or graduate to red. + +### 5.3 Residual >= 13 (red): hard-stop + +No new pilot signed, no new release shipped, until either: + +- the residual drops below 13 via additional mitigations, **or** +- the founders (Agent #1 + Agent #28) explicitly sign off in writing + with a documented mitigation roadmap and a target re-review date + not later than 30 days out. + +The founder sign-off record is committed to +`docs/compliance/risk/acceptances/<R-ENT-NN>-founder-<yyyy-mm-dd>.md` +and is referenced by ID from this register's row "Residual sign-off" +column. + +At v1 issue **no risk is in the red band** after mitigation. Every +row sits at residual <= 6. + +--- + +## 6. Operating principles + +These are the rules the register lives by — they are not +risk-specific, they apply across the document. + +### 6.1 Owners are named individuals + +Risk owners must be named individuals, identified by agent number, +not roles. No "TBD," no "the security team." If a row's owner is +ambiguous, Agent #40 escalates to Agent #36 within 24 hours of +discovery. The escalation must resolve into a single named agent +number — not into a working group. + +### 6.2 Mitigations must be testable + +Every mitigation listed under a risk must be verifiable by a test, an +audit, a code review, or an inspectable artefact (commit, ADR, doc). +"We will be careful" is not a mitigation. "ADR 0010 SHA-256 pins the +snarkjs bundle and CI fails on mismatch" is. If a mitigation cannot +be verified, the owner must propose how to verify it within 7 days, +or the mitigation is removed and the residual re-scored. + +### 6.3 Risks must be re-assessed on event triggers + +Beyond the calendar cadence in §4, risks must be re-assessed when +**any** of the following occurs: + +- A regulator notification (DPB, RBI, SEBI, a bank's internal + auditor) changes — i.e., a new rule, a new circular, a new + interpretation memo. +- The customer base composition shifts > 20 % — e.g., the largest + customer's share crosses the 20-point threshold up or down. +- A competitor enters the market (a new ZK identity vendor opens + India operations) or exits (a domestic incumbent shutters its + identity product). +- A major dependency reaches end-of-life (snarkjs deprecation, + circomlib break, Node.js LTS expiration, Base L2 deprecation, Hardhat major bump). +- A security incident at any severity is declared (links into the + incident-response runbook drafted A40-W1-Tue). + +The re-assessment fires within 5 business days of the triggering +event and updates the affected rows' "Last reviewed" column. + +### 6.4 Register-quality discipline + +Agent #40 owns register-quality. A row that has gone > 60 days +without a "Last reviewed" date update is a discipline failure, not a +risk: it is fixed in the next weekly walk and a note is added to +`docs/compliance/risk/walks/<date>.md` recording the lapse. + +### 6.5 Cross-references are bidirectional + +When a threat-model `A-NN` row references this register (e.g., "this +attack materialises R-ENT-03"), the corresponding R-ENT row must +reference back. CI runs a cross-reference linter weekly +(compliance-roadmap-v1 §8.5). + +--- + +## 7. Risk-residual-acceptance sign-offs (v1) + +Each row's residual-acceptance signature is listed for v1 issue.

The control covers tone-from-the-top, the written code of conduct, the disciplinary process when the code is breached, and the channels through which staff (and third parties) raise concerns without retaliation. + +## How ZeroAuth meets this control + +ZeroAuth's commitment to integrity is anchored in two source-of-truth documents that every contributor — human or AI — is held to. + +`CLAUDE.md` at the repository root carries the engineering constitution. It enumerates the non-goals — "never accept raw biometric data over the wire", "never log biometric-derived raw data", "never expose admin actions without an audit row", "never expose one tenant's data to another", "never deploy a verifier whose circuit version is not in `/adr/`" — and labels them as enforceable in code review. + +The four "Critical language rules" block marketing copy that overstates the cryptographic guarantee. Forbidden phrases (the verifier is cryptography, not AI), unqualified deepfake-immunity claims (visual-spoofing-class at the verification layer is the legitimate scope), and the "production stack" formulation (to be replaced with "live reference implementation") are pre-commit-hook-rejected. These are not advisory. The pre-commit hook and the CI mirror gate check staged diffs for them, and a violating commit is rejected before push and again at the CI ingress. + +The companion `CODE_OF_CONDUCT.md` extends the standard contributor-covenant baseline. It is referenced from `README.md` and `CONTRIBUTING.md`. Every onboarding ticket in `docs/plan/bfsi-v1/agents/` is expected to start with reading both files plus `06-ways-of-working.md`. The plan tree itself — landed in commit `5e3b79d` ("land BFSI v1 production plan under docs/plan/bfsi-v1") — codifies that every commit traces to a pain point in `01-pain-points.md` and references its ticket ID; this gives an auditor an end-to-end trail from intent ("close P-7 — bank cannot evidence the audit log") to artefact (commit `a475ed8` adding the hash chain). + +Tone-from-the-top is reinforced through the weekly Friday status post (per `06-ways-of-working.md`, "Daily cadence"). Every one of the 50 agents files a four-line status. The founder (Agent #1) and the CCO (Agent #36) read all 50. The cadence makes integrity lapses observable: a status that quietly omits a missed gate, or that obscures a ticket slip, is visible to the leadership trio at the next 18:00 IST Friday read. + +A standing-instructions section in `CLAUDE.md` ("When you (Claude) get stuck") tells contributors what to escalate and where; the escalation matrix in `06-ways-of-working.md` "Escalation" makes the same explicit for humans. The matrix names a 4-hour SLA for customer escalations and a pageable 15-minute SLA for production sev-1 incidents — both impossible to honour without an integrity-first culture in the responding role. + +The Phase 0 audit findings doc at `docs/security/audit-findings.md` is the public artefact of "we say what we found and we close it." Every finding has a status, a closing commit hash where applicable, and a target sprint for the open items. Hiding a finding would constitute a code-of-conduct breach. The doc is gated by the same CI as the rest of the repo and any silent deletion of a row is detectable in `git log`. The Phase 0 closure trail (commits `02e1734`, `ee6aad4`, `e98d158`, `a475ed8`, `c09c081`, `a1bbc47`, `5425032`) is the concrete demonstration that the team holds itself to the finding ledger. + +A formal annual code-of-conduct attestation (every agent signs that they have read and will abide by `CODE_OF_CONDUCT.md` + `CLAUDE.md`) is the gap remaining. It lands week 13 alongside the DPB §17 DPO appointment filing, per the compliance roadmap `D-Q1-19`.

The board-equivalent function during Phase 0–2 is the trio of Agent #1 (founder / CTO), Agent #36 (CCO), and Agent #42 (head of partnerships / business owner). + +The plan tree explicitly names these three as the standing reviewers for every phase-exit gate: see `docs/plan/bfsi-v1/00-README.md` and the monthly cadence row in `06-ways-of-working.md` "Phase progress review with Role 1 + Role 28 + Role 36 + Role 42". The trio holds the go / no-go authority at Phase 0 (week 2), Phase 1 (week 12), Phase 2 (week 26), Phase 3 (week 39), and Phase 4 (week 52). A no-go at any gate is the strongest available oversight intervention. + +Oversight cadence is fixed in writing. The monthly review on the 1st of the month covers phase exit-gate status. The mid-month risk-register review on the 15th (with Role 40, the risk owner) reviews material risks. The end-of-month cost / spend review (with Role 50, the operations lead) reviews budget vs. actual. Three reviews per month; together they form the management-control loop the board needs to satisfy CC1.2. + +The quarterly compliance retrospective (`docs/compliance/retros/<year>-<q>.md`, per `compliance-roadmap-v1.md` §8.1) is signed off by both Agent #36 and Agent #1 — that two-signature rule is the load-bearing independence guarantee in the absence of a fully formed external board. + +Management's risk-management process is captured in the compliance roadmap §7 ("Open dependencies and risks"). Eight named risks (R-COMP-01 through R-COMP-08) each carry a likelihood, an impact, an owner, and a mitigation plan. R-COMP-01 (DPDP rules notification mid-evidence-period) and R-COMP-08 (cross-border-transfer rule tightening) are the two with the highest "regulatory shift" exposure. The mitigation has an explicit "weekly check in the Friday status post" attached, which lands the risk on the founder's desk every week. + +R-COMP-04 (bank pilot 1 contract slip) and R-COMP-05 (RBI sandbox not accepted) are the two highest "customer / regulator decision" exposures; each has a documented fall-back plan that prevents a single external decision from blocking the whole programme. + +The board-equivalent review of internal control effectiveness is the Phase exit gate. Phase 0 closes 21 audit findings (tracked in `docs/security/audit-findings.md`). Phase 1 closes the bank demo (`docs/plan/bfsi-v1/02-bank-demo.md` — 5 scenes plus the integrity-evidence Scene 5). Phase 2 closes SOC 2 Type I + ISO Stage 1. Phase 3 closes SOC 2 Type II evidence period + ISO Stage 2 certificate issuance. Phase 4 closes mainnet deployment + first paid bank go-live.

The agent-tickets directory (`docs/plan/bfsi-v1/agents/agent-<NN>-*.md`) further turns each role into a daily Mon-Fri ticket list for weeks 1–4 with a 5-field Definition of Done per ticket (Done-when, Output, Verify, Reviewer, Depends-on). + +Reporting lines are explicit in every per-agent file. As an example from this control's owner: `agents/agent-38-compliance-soc2.md` opens with "Reports to: Agent #36." The line VPs report to the CTO (Agent #1). The CCO (Agent #36) reports to Agent #1 alongside the line VPs but has independent escalation authority to the board-equivalent on compliance matters (per `06-ways-of-working.md` "Escalation"). The DPO (Agent #41) reports to the CCO but has a statutory independent-judgement carve-out under DPDP §17 — captured in `docs/compliance/privacy/data-inventory-v1.md` and the §17 filing referenced in `compliance-roadmap-v1.md` D-Q1-19. + +Authority is mapped to repository paths through the sub-agent rules in `06-ways-of-working.md` "Sub-agent rules". Touching `src/services/audit.ts` requires both `security-reviewer` and `cryptographer-reviewer` sub-agent approval; touching `src/middleware/tenant-auth.ts` requires `security-reviewer`; touching `circuits/**` requires `cryptographer-reviewer`; touching `contracts/**` requires both. The two sub-agents are installed at `.claude/agents/security-reviewer.md` and `.claude/agents/cryptographer-reviewer.md` per `CLAUDE.md` "Subagents available". + +The branching workflow (ADR 0011, commit `51bc705`) backs the authority-by-path map with technical enforcement: every PR to `main` requires CI green + sub-agent APPROVE before merge. `--no-verify` is forbidden. A reviewer that posts REQUEST_CHANGES blocks the merge until addressed, with a 24-hour escalation to Role 1 if ignored. + +Segregation of duties is encoded both in role definitions and in technical access controls. The compliance roadmap §6 ("Vendor and counsel calendar") names the agent owner for each external relationship — Agent #37 owns DPDP counsel, Agent #27 owns the external cryptographer, Agent #38 owns the SOC 2 + ISO auditor relationships.

The roster in `03-team.md` is sequenced — engineering line VPs (roles 1–5) and the load-bearing P0 close-out roles (roles 6, 8, 26, 27, 36) are hired or contracted first. The GTM ramp (roles 42–49) follows once the Phase 1 demo is reliably running. + +The compliance roadmap `D-Q1-02` (week 1) commits to publishing the SOC 2 + ISO + DPDP external counsel and auditor shortlists, which are the gating contracted-talent decisions. The week-4 deadline (`D-Q1-07`, `D-Q1-08`, `D-Q1-05`) for engagement-letter signature means the senior external relationships are all locked before the SOC 2 evidence period opens. + +Competence is reinforced through pair-review at the technical boundary. Every change to a sensitive path (auth, crypto, audit, tenant boundaries — see `06-ways-of-working.md` "Sub-agent rules") triggers the `security-reviewer` or `cryptographer-reviewer` sub-agent. The sub-agent acts as the second pair of eyes that catches competence gaps in the moment. A reviewer that posts REQUEST_CHANGES blocks the merge until the author has addressed the gap, and a 24-hour SLA escalation to Agent #1 is in the escalation matrix. + +The Phase 0 audit-finding closure trail is the team's first delivered evidence of competence under pressure. 5 P0 findings closed in 2 weeks (C-1, C-3, C-7, C-4, C-8 — see `docs/security/audit-findings.md`), each with a closing commit, each with a regression test. The trail is reviewed in the Phase 0 exit gate (week 2) and feeds back into the per-role year-end performance evaluation. Commits `02e1734`, `ee6aad4`, `e98d158`, `a475ed8`, `c09c081` are the concrete artefacts behind that evidence claim. + +Formal training programmes are the gap.

The trusted-setup ceremony (week 10, `D-Q2-14`) doubles as a hands-on competence-building exercise for the cryptography line (Agents #11, #12, #13, #27). + +Retention discipline is operations-led. The cost / spend review on the last Friday of every month (per `06-ways-of-working.md` "Monthly cadence") includes a "people" line where Agent #50 reports headcount + turnover + remediation plans.

The `docs/compliance/dpdp-2t-commitments-memo-v0.md` ("commitment hashes and DIDs are not personal data") is the first counsel-facing artefact; a v1 lands after the week 4 DPDP-counsel call, per `compliance-roadmap-v1.md` D-Q1-05. + +Customer-facing communications are mediated through three published surfaces: the docs site at `https://docs.zeroauth.dev/` (Docusaurus), the marketing site at `https://zeroauth.dev/`, and the in-product copy in `dashboard/`. The docs site is the source of truth for the API contract (`docs/api_contract.md`), error codes (`docs/error_codes.md`), and the architecture decision trail. The marketing site is the controlled-claims surface — the language rules in `CLAUDE.md` ("AI-powered" banned, "deepfake-immune" only with the visual-spoofing-class qualifier, "production stack" replaced with "live reference implementation", "Dr. Pulkit" replaced with "Senior Software Engineer") prevent overstated security claims escaping into external messaging. + +Vendor security expectations are codified through the DPA process.

Each vendor relationship is owned by a named agent. + +Inbound external security communications are routed through `SECURITY.md` at the repository root. This document is the GitHub-recognised security-policy file and gives an external researcher a single inbox to report a vulnerability into. The bug-bounty programme (target week 27 launch, per `compliance-roadmap-v1.md` D-Q3-03) layers a formal, scoped channel on top of `SECURITY.md`. + +Regulator notification SLAs are explicit. DPDP §8 mandates 72-hour breach notification; the SOP for that lands as `docs/compliance/dpdp/breach-notification-playbook.md` (target week 6 per the DPDP-counsel SoW).

The product-level objective ("zero-knowledge identity verification layer for India's regulated industries — BFSI, healthcare, government") is stated in `CLAUDE.md` and elaborated in `docs/plan/bfsi-v1/00-README.md` (phase map) and `docs/plan/bfsi-v1/01-pain-points.md` (the 10 BFSI pain points that ZeroAuth solves). The phase-level objective is the Phase 0 exit gate (close 21 audit findings) and the Phase 1 exit gate (Anchor Bank demo runs end-to-end without intervention). The ticket-level objective is the Done-when + Verify pair on each agent ticket in `docs/plan/bfsi-v1/agents/`. + +Risk identification is structured around two complementary catalogues. `docs/threat_model.md` is the technical-risk catalogue — every `A-NN` row carries a class (STRIDE), a surface, a description, a mitigation, a test status, and an audit-signal status. It is required reading for the `security-reviewer` and `cryptographer-reviewer` sub-agents at session start. The opening note instructs every contributor to extend the document on each new endpoint, new secret-or-PII dependency, new circuit change, or new audit-log write path. The threat model has been updated in commit `573ff5d` ("track audit findings and update threat model for Phase 0 closures") as the Phase 0 findings closed — demonstrating the maintenance rhythm. + +The compliance-risk catalogue lives at `docs/compliance/compliance-roadmap-v1.md` §7. Eight named risks (R-COMP-01 through R-COMP-08) each carry a class (regulatory shift, vendor-selection slip, cross-line schedule dependency, customer dependency, regulator decision, technical/security, vendor-side disruption, regulatory shift), a likelihood, an impact, an owner, and a mitigation plan. R-COMP-01 (DPDP rules notification mid-evidence-period) has the weekly-Friday-check mitigation; R-COMP-02 (evidence collector tool not finalised) has a hard week-10 deadline; R-COMP-03 (trusted-setup ceremony slip) has a 26-week-of-contingency mitigation; R-COMP-06 (smart-contract audit Critical finding) has a 4-week remediation buffer; the others each have explicit named mitigations. + +The closed-loop process is captured in `06-ways-of-working.md` "Documentation hygiene": every PR is responsible for updating `docs/threat_model.md` (new attack vector mitigated or identified) and `docs/security/audit-findings.md` (finding closed with closing commit hash). The compliance roadmap §8.4 mandates the quarterly update cadence on the roadmap itself. + +Risk assessment is owned but not single-pointed. Each `A-NN` threat-model row has an implicit mitigation owner via the path-to-role map in `06-ways-of-working.md` "Sub-agent rules" — A-01 (cross-tenant data read) sits with Role 7 (tenancy), A-02 (replayed proof) with Roles 6 + 11, A-14 + A-22 (audit-chain attacks) with Role 8, etc. Each R-COMP-NN compliance risk has an explicit named owner.

The two flagship anti-fraud constructions are: + +**The per-tenant audit hash chain (ADR 0013).** `audit_events` carries `previous_hash` + `event_hash` columns; every row is `SHA-256(canonical_json(event_data) || previous_hash)` per RFC 8785 JSON Canonicalization. The chain is per-tenant so a noisy tenant cannot delay another tenant's chain head. The "what the chain does NOT defend against" section of the ADR explicitly names the residual fraud surfaces (DBA who deletes wholesale + disables drift detector; compromised process that controls writes AND poisons the serialiser; full pause-and-tamper) and routes each to a compensating defence. Implementation: commit `a475ed8`; integrity-check endpoint commit `d634b2d`; `appendAuditEvent`-only-write enforcement commit `c09c081`. + +**The daily on-chain anchor (ADR 0014).** Each tenant's chain terminal hash is anchored once per day on Base L2 via the `AuditAnchor` contract (commit `d6c6a4e`). The contract is write-once for `(tenantIdHash, dayUtc)` — designed so the bank's auditor can independently verify "this chain existed at this point in time and has not been re-written since" without trusting any ZeroAuth process. The `verify-audit-chain.sh` helper takes a DB dump and replays the chain row-by-row, then queries Basescan for each `AnchorRecord` and asserts the terminal-hash match. Zero ZeroAuth runtime dependencies. + +The two controls together form a defence-in-depth pair: the in-DB chain catches single-process tampering; the on-chain anchor catches process-and-DBA collusion. + +**Circuit-version pinning (ADR 0015).** A second class of fraud — running a verifier whose vkey does not match the circuit version compiled into the binary — is closed by the boot-time SHA-256 check in `src/services/zkp.ts` (commit `e98d158`).

The scopes (sampled from the type definitions) cover the public capabilities: `device.register`, `user.enroll`, `verification.submit`, `attendance.submit`, `audit.read`, `proof-pairing.create`, `proof-pairing.submit`, etc. Each `/v1/*` route declares the required scope; the `authenticateTenantApiKey` middleware in `src/middleware/tenant-auth.ts` (a) authenticates the key and (b) authorises the request by intersecting key-scope-set with route-required-scope. A request whose key lacks the route's scope returns `403 forbidden_scope`. + +API-key issuance is mediated by the developer console (`/api/console/keys`). Console JWTs are required to mint a key; the per-console-user authorisation determines which tenants the user can issue keys for. The key format `za_{live,test}_{48 hex}` is documented in `CLAUDE.md` "Load-bearing capabilities" §2. Keys are SHA-256-hashed at rest in `api_keys` table; the cleartext is shown to the console user exactly once at issue time.

Each key-related write (issued, rotated, revoked, scope-modified) is logged through `appendAuditEvent` (commit `a475ed8`); the hash chain (ADR 0013, commit `27ed93c`) makes the trail tamper-evident; the on-chain anchor (ADR 0014, commit `d6c6a4e`) makes it externally verifiable.

The `scripts/check-dep-trail.sh` script audits the dependency tree against `/adr/` — every direct dep must trace to an ADR. The ADR-trail scan is one of the commit-time gates per `06-ways-of-working.md` "Commit-time gates" §6. + +Concrete ADR trail examples: ADR 0001 (`adopt-express-rate-limit-as-direct-dep`), ADR 0003 (`adopt-playwright-for-e2e`), ADR 0005 (`adopt-nodemailer-for-smtp`), ADR 0007 (`iot-serialport-dependency`), ADR 0008 (`iot-snarkjs-poseidon-lite`), ADR 0010 (`android-webview-snarkjs-bundling`), ADR 0012 (`android-keystore-module-deps`), ADR 0016 (`zod-input-validation`). The grandfathered initial deps are inventoried in ADR 0000. + +**Layer 2: nightly CVE monitor.** `scripts/cve-monitor.sh` (commit `f8a756c`) scans the dependency tree against the GitHub advisory database. A high-severity finding pages the on-call rotation. The fixture-based regression guard `tests/cve-monitor.test.ts` (also commit `f8a756c`) — plus the vulnerable-lockfile fixture at `tests/fixtures/vulnerable-lockfile/` — verifies the monitor itself doesn't drift silent.

The mechanism prevents the "swapped vkey" class of unauthorised-software introduction (an attacker who can write to the vkey file cannot make the service accept it without also changing the SHA-256 constant in source). ADR 0015 §"What we do NOT support" explicitly rejects a `--force` flag. + +For the Android prover: ADR 0010 (`android-webview-snarkjs-bundling`) + commit `d18460f` pin the prover-asset hashes in a Gradle gate — a tampered prover bundle fails the build. Server-side Play Integrity enforcement (commit `0224be4`) on the `/v1/proof-pairing/submit` endpoint rejects submissions from devices that don't present `MEETS_DEVICE_INTEGRITY` + `MEETS_BASIC_INTEGRITY`.

The `contracts/` directory holds Solidity 0.8 sources; the deploy-addresses are pinned in `contracts/deployed-addresses.json`. The forthcoming Trail of Bits / equivalent audit (compliance roadmap D-Q2-08, weeks 16–24) is the third-party verification of contract integrity.

The bug-bounty programme (compliance roadmap D-Q3-03, target week 27) layers a formal scoped channel with HackerOne / BugCrowd / YesWeHack — the choice is the Phase 3 deliverable.

Every incident or finding gets a row with: ID (`C-NN` sequenced), title, severity (P0/P1/P2/P3), status (`CLOSED` / `OPEN` with target sprint / `TRACKED` for future-phase items), closing commit hash for closed rows, and notes — usually including the regression-test reference and the threat-model row that captures the residual surface. + +The Phase 0 closure trail is the demonstration of the loop. 21 findings identified in the readiness audit. 5 P0 + 4 P1 closed in 2 weeks. Each closure carries (a) a closing commit hash, (b) a regression test that pins the closure, (c) a threat-model row update where a new attack surface was identified.

Regression test: `tests/tenant-isolation.test.ts`. Threat-model row A-01. + +The closed-loop closing-the-loop demonstration: commit `573ff5d` ("track audit findings and update threat model for Phase 0 closures") is a single commit that simultaneously (a) updates the audit-findings doc with the new closure status, (b) extends the threat model with the corresponding `A-NN` row, and (c) flows the lesson back into the control catalogue. + +Future incidents follow the same pattern. The expectation in `06-ways-of-working.md` "Documentation hygiene" is: every PR that closes a finding updates `docs/security/audit-findings.md` (with the closing commit hash) and `docs/threat_model.md` (with the new mitigation or attack vector). The closed-finding regression suite (`tests/security/regression.spec.ts`, lands C-023 / sprint 2) is the structural prevention layer — once it lands, every PR runs the union of closed-finding tests and rejects any regression. + +Post-incident review for non-finding incidents (e.g., a production outage, a customer-reported defect) is the gap.

Mandating blockchain rails raises integration cost without buying a single pilot. The substance — Pramaan ZK identity verification over biometric commitments + hash-chained audit log — does not require blockchain. This ADR amends ADR 0014. The platform ships with three independent provider slots: did_provider: off-chain (default) | base-sepolia | base-mainnet | custom-chain verifier_provider: off-chain (default) | on-chain audit_anchor_provider: none (default) | signed-transcript | base-sepolia | base-mainnet | witness-cosign A tenant with all defaults runs the platform with zero blockchain dependency. Boot succeeds without BLOCKCHAIN_PRIVATE_KEY. Anchor cron skips default tenants. Identity register does not call DIDRegistry unless the tenant opts in. The Auth0 differentiation pitch holds without any blockchain mention: credential storage as commitments, breach blast radius as field elements, SIM-swap defence via StrongBox-bound DID, transaction binding inside the proof, zero SMS marginal cost, hash-chained auditable log. None of these arguments depend on a chain. Existing on-chain artefacts (DIDRegistry, Groth16Verifier, AuditAnchor on Base Sepolia) remain as provider implementations. The 403-test backend stays green; the chain-related tests gain skip branches for off-chain provider mode. Closes the platform pivot per user directive: 'currently we have to be blockchain agnostic, since Indian companies don't trust blockchain much we have to be blockchain agnostic. Currently our requirement is to be a fully fledged platform with the mobile app.' [no-test] markdown-only ADR; implementation refactor lands in the next commit which adds the provider gates to anchor-job, identity service, and the tenant security_policy schema. --- adr/0017-blockchain-agnostic-posture.md | 161 ++++++++++++++++++++++++ 1 file changed, 161 insertions(+) create mode 100644 adr/0017-blockchain-agnostic-posture.md diff --git a/adr/0017-blockchain-agnostic-posture.md b/adr/0017-blockchain-agnostic-posture.md new file mode 100644 index 0000000..647a8b0 --- /dev/null +++ b/adr/0017-blockchain-agnostic-posture.md @@ -0,0 +1,161 @@ +# ADR 0017 — Blockchain-agnostic posture + +- **Status:** Accepted +- **Date:** 2026-05-28 +- **Phase:** Phase 1, pivot week 3 +- **Supersedes / amends:** ADR 0014 (on-chain anchor cadence) — anchoring becomes opt-in, not mandatory.

The blockchain pieces were defence-in-depth bolt-ons, not the load-bearing primitive. + +The substance — Pramaan ZK identity verification, biometric-commitments, hash-chained audit log — stands on its own. Blockchain is a pluggable provider for one specific value-add (independently verifiable anchor), not the core. + +## Decision + +ZeroAuth is **blockchain-agnostic**. The platform ships with three independent provider slots, each opt-in per tenant: + +### 1. Identity provider — where DIDs live + +Defaults to **off-chain**. The DID + commitment tuple is the system-of-record in the `users` table (`tenant_users` today; PII-stripped variant in Phase 1) in the tenant's database. The DID is a stable identifier the tenant assigns, scoped to `(tenant_id, environment)`. + +Optional providers (selected via `tenant.security_policy.did_provider`): + +- `"off-chain"` — DEFAULT. DID lives in DB. No external dependency. +- `"base-sepolia"` — register every DID on `DIDRegistry` on Base Sepolia (existing). Adds ~3 s to enrollment latency. +- `"base-mainnet"` — same, on Base mainnet (production future). +- `"custom-chain"` — pluggable; the tenant supplies an RPC + a `DIDRegistry`-compatible contract address. + +### 2. Verifier provider — where Groth16 proofs are verified + +Defaults to **off-chain snarkjs**. The verifier runs in-process, loading `verification_key.json` per ADR 0015. This is what the dashboard demo, every customer pilot, and the production verifier service uses. + +Optional providers (selected via `tenant.security_policy.verifier_provider`): + +- `"off-chain"` — DEFAULT. `snarkjs.groth16.verify` in `src/services/zkp.ts`. +- `"on-chain"` — additionally re-verify on Base via `Groth16Verifier`. Adds ~10 s wall-clock per verification. Useful only for tenants who insist on the on-chain re-verification as defence-in-depth. + +### 3. Audit anchor provider — how the audit chain is independently verifiable + +Defaults to **none**. The hash chain (ADR 0013) is the tamper-evidence primitive; it is fully off-chain and verifiable from a database dump. The anchor is an additional layer that lets a third party verify history without needing the DB dump. + +Optional providers (selected via `tenant.security_policy.audit_anchor_provider`): + +- `"none"` — DEFAULT. Hash chain only. Tenant's auditor verifies via DB dump. +- `"signed-transcript"` — ZeroAuth produces a daily signed transcript (ed25519 over the chain's terminal hash + day). The signing key is published; the bank's auditor checks the signature. NEW PROVIDER — implementation lands in a sprint-2 commit. +- `"base-sepolia"` — daily anchor on Base Sepolia `AuditAnchor` (existing infrastructure, commit `d6c6a4e`). Gas-free. +- `"base-mainnet"` — same on Base mainnet. +- `"witness-cosign"` — daily transcript co-signed by a named third party (e.g. the bank's own internal auditor, or a notary service). NEW PROVIDER — Phase 3. + +### How a tenant configures providers + +`tenants.security_policy` JSONB carries: + +```json +{ + "did_provider": "off-chain", + "verifier_provider": "off-chain", + "audit_anchor_provider": "none", + "audit_anchor_signing_key_id": null, + "base_rpc_url": null, + "did_registry_address": null, + "groth16_verifier_address": null, + "audit_anchor_contract_address": null +} +``` + +A tenant with all defaults runs the platform without any blockchain RPC, key, or contract — a clean off-chain deployment. + +A tenant that opts into `signed-transcript` anchoring gets the value of "independently-verifiable history" without the operational + commercial overhead of running anything on a blockchain. + +A tenant that opts into `base-sepolia` or `base-mainnet` adds the blockchain-anchored layer on top; the platform still works if the chain RPC is unavailable (the chain is best-effort). + +### Defaults rationale + +Defaults are **off-chain**, **off-chain**, **none** because: + +- Most customers will never opt into a blockchain provider. +- A new customer setting up a tenant should not need to know what Base is, what a Groth16 contract is, or what a daily anchor cron is. +- Operational risk: an RPC outage on a chain provider should never block enrollment or verification. +- Commercial risk: per-anchor gas spend at scale (50 tenants × 365 anchors/year × ~$5 = $90 k/year on mainnet) needs explicit opt-in with a CFO-approved budget line, not silent default-on. + +## What this changes + +| Surface | Before | After | +|---|---|---| +| `src/services/blockchain.ts` | Hard-loaded at boot; `BLOCKCHAIN_PRIVATE_KEY` required for `live` | Optional.

Source stays. | +| `contracts/Groth16Verifier.sol` | Tracked in `contracts/deployed-addresses.json` and verified on-chain by ADR 0015 | Same; still tracked; still used when a tenant opts into on-chain verification. | +| Dashboard "Audit Integrity" view (commit `0848640`) | Shows on-chain anchor link unconditionally | Shows the link only when the tenant has an anchor provider; otherwise shows "Off-chain hash chain only (signed transcript not enabled)". | +| Demo runbook Scene 5 | Shows on-chain anchor + Basescan | Shows hash-chain + the signed-transcript path; on-chain anchor is presented as an optional add-on, not the default. | +| `docs/plan/bfsi-v1/01-pain-points.md` P4 mitigation language | "hash-chained DB + on-chain anchor on Base" | "hash-chained DB + signed daily transcript (default) or on-chain anchor (opt-in)". | + +## What this does NOT change + +- The Pramaan ZK identity verification protocol itself. +- `identity_proof.circom` circuit. +- The `EXPECTED_VKEY_SHA256` boot check (ADR 0015). +- The hash-chained audit log (ADR 0013). +- The on-device biometric → commitment pipeline. +- The Groth16 proof-of-knowledge of secret opening the commitment. +- Any test in the existing test suite (403 backend tests stay green; the chain-related tests just gain a "skip when provider is off" branch). + +## How we sell this vs Auth0 / Okta — the language stays the same + +The Auth0 differentiation pitch we have been making does not depend on blockchain at all: + +- "Credential storage: Auth0 stores hashes + MFA seeds; we store Poseidon commitments only." +- "Breach blast radius: their DB exfil yields PII; ours yields field elements with no PII linkage." +- "SIM-swap defence: StrongBox-bound DID + biometric local gate, no SMS in the loop." +- "Transaction binding: Poseidon over (amount, payee, ts) inside the proof — cryptographic, not OTP." +- "Per-auth marginal cost: zero SMS in the loop." +- "Audit log: hash-chained, independently verifiable from a DB dump." + +Notice: none of these arguments mention a blockchain.

The platform is now blockchain-agnostic by default: a tenant whose security_policy is null, {}, or doesn't carry the new provider keys gets the off-chain triple (did_provider='off-chain', verifier_provider='off-chain', audit_anchor_provider='none') and never touches a chain RPC. src/services/tenant-providers.ts — new pure-function resolver. Pure: no DB, no env, no IO. Reads a TenantSecurityPolicy JSONB, returns a ResolvedProviders triple plus the chain-config strings. Invalid provider values fall back to defaults so a malformed JSONB row never crashes the hot path (identity register + anchor cron). src/services/identity.ts — registerIdentity now accepts an optional securityPolicy argument. The on-chain DID registration is gated: resolveProviders(policy).didProvider === 'off-chain' skips the chain call entirely. Old callers without a policy get the off-chain path, preserving backward compatibility. src/services/anchor-job.ts — runDailyAnchorJob queries security_policy alongside tenant id, calls resolveProviders, and skips any tenant whose auditAnchorProvider === 'none' before the per-tenant work begins. A new test asserts the skip behaviour. src/services/blockchain.ts — boot init is now non-fatal. If BLOCKCHAIN_PRIVATE_KEY or contract addresses are missing, the service logs a degraded-mode warning and isBlockchainReady() returns false. The platform boots clean without any chain config. src/routes/v1/zkp.ts — registerIdentity call now threads the tenant context's security_policy through. src/types/index.ts — TenantSecurityPolicy carries the three provider keys plus the chain-config strings. Type-only change; the DB JSONB column is unchanged. Tests: - tests/tenant-providers.test.ts (8 tests, all green) — defaults, explicit providers per slot, invalid-value fallback, chain config pass-through. - tests/anchor-job.test.ts updated to thread security_policy through tenant fixtures via the new chainAnchorTenant() helper; a skip test verifies provider=none tenants are bypassed. 411 backend tests green; 35 suites pass; 14 skipped (public-route exceptions). No new deps.

The endpoint accepts the (did, commitment) tuple computed entirely on-device by the mobile/biometric pipeline — never a biometric template, an image, or an embedding. src/services/db.ts: - tenant_users gains 'did' + 'commitment' columns via ALTER TABLE (idempotent for existing deployments). UNIQUE constraint on (tenant_id, environment, did) WHERE did IS NOT NULL. src/services/identity.ts: - New exports: registerFaceFirstIdentity(), IdentityValidationError, IdentityAlreadyExistsError. The function validates DID + commitment format, asserts uniqueness per (tenant_id, environment, did), persists the row with did/commitment populated, and optionally queues an async chain DID registration when the tenant's security_policy.did_provider opts in. Default tenants run pure-DB enrollment with zero chain dependency. src/routes/v1/identity.ts: - New POST /v1/identity/register endpoint mounted under the existing identity router. Uses authenticateTenantApiKey with zkp:register scope + pgRateLimit (30/min, keyed by API key). Translates service-level errors to 400/409 HTTP responses. tests/schema-purity.test.ts: - Allowlist expanded to permit did + commitment on tenant_users. tests/identity-register-face.test.ts: - 7 tests pinning the route behaviour: auth required, 201 on success, audit row written, 400 on invalid_did / invalid_did_format, 409 on did_already_registered, and a defence-in-depth test that biometric-like extras in the request body never reach the service layer. The legacy POST /v1/auth/zkp/register that accepts base64 biometricTemplate is retained for the W3 demo client + existing test fixtures but is now deprecated for new integrations — the face-first path is the production register surface. 419 backend tests green, 36 suites, 14 skipped public-route exceptions.

The endpoint accepts the on-device-generated Groth16 proof plus the claimed DID, looks the user up in (tenant_id, environment, did), asserts publicSignals[0] matches the stored commitment, then runs snarkjs.groth16.verify against the platform's pinned verification key (ADR 0015). Five-step flow: 1. findUserByDid() returns the (id, commitment) for the claimed DID or null. Null → uniform 401 verification_failed. 2. publicSignals[0] case-insensitive compare against the stored commitment. Mismatch → uniform 401 verification_failed (same wire-level error as did_unknown, for enumeration defence). 3. verifyBiometricProof() runs snarkjs.groth16.verify(vkey, publicSignals, proof). The vkey is the boot-time-validated copy from ADR 0015. proof_invalid → uniform 401. 4. On success: create a UserSession in sessionStore, issue access + refresh tokens with did in the JWT claims. 5. Write an audit row on every path (success or failure) with the reason in metadata. Path-by-path reasons: did_unknown, commitment_mismatch, proof_invalid, internal_error, or success. Service-side additions: - src/services/identity.ts gains findUserByDid(tenantId, env, did) which returns { id, commitment | null } or null. Tests (8/8 green): - Scope gate on zkp:verify. - 400 invalid_did when DID missing; 400 invalid_request on bad publicSignals shape. - 401 verification_failed when DID unknown — uniform error. - 401 verification_failed on commitment mismatch — snarkjs NOT called (verifyBiometricProofMock never invoked); enumeration defence holds. - 401 verification_failed when snarkjs rejects the proof. - 200 with verified=true + sessionId + tokens on a clean verify. - Case-insensitive commitment compare (UPPERCASE presented vs stored lowercase). Routing: mounted at /v1/identity/verify under the existing identity router. The legacy /v1/auth/zkp/verify endpoint remains for backward compat with the W3 demo client — that endpoint does not look up by DID + commitment, so it is fundamentally weaker than this one and should be deprecated for new integrations. 428 backend tests green, 37 suites, 14 skipped public-route exceptions. No new deps. No chain dependency on the verify path. --- src/routes/v1/identity.ts | 200 ++++++++++++++++++++++ src/services/identity.ts | 20 +++ tests/identity-verify-face.test.ts | 255 +++++++++++++++++++++++++++++ 3 files changed, 475 insertions(+) create mode 100644 tests/identity-verify-face.test.ts diff --git a/src/routes/v1/identity.ts b/src/routes/v1/identity.ts index b844bb9..230989a 100644 --- a/src/routes/v1/identity.ts +++ b/src/routes/v1/identity.ts @@ -5,11 +5,15 @@ import { sessionStore } from '../../services/session-store'; import { issueTokens, verifyToken } from '../../services/jwt'; import { logger } from '../../services/logger'; import { recordAuditEvent } from '../../services/platform'; +import { v4 as uuidv4 } from 'uuid'; import { registerFaceFirstIdentity, + findUserByDid, IdentityValidationError, IdentityAlreadyExistsError, } from '../../services/identity'; +import { verifyBiometricProof } from '../../services/zkp'; +import type { UserSession, ZKPVerificationRequest } from '../../types'; const router = Router(); @@ -103,6 +107,202 @@ router.post('/register', }, ); +/** + * POST /v1/identity/verify + * + * Face-first identity verification (ADR 0017).

We replace the credential database — the thing that breaches and creates DPDP class-action exposure.** + +--- + +## The thesis + +Indian BFSI's largest digital-identity liability today is the **credential database**. + +Auth0, Okta, Ping, Microsoft Entra, and AWS Cognito all store password hashes, MFA seeds, recovery codes, and — in the regulated-vertical configurations Indian banks actually buy — biometric templates and KBA answers. Every breach of that database is a reportable event under DPDP §8(6) and the proximate cause of class-action exposure under DPDP §13. + +The 2024 Indian BFSI incidents the room remembers — StarHealth, RailYatri, the HDFC Life partner exfil, the ICICI Lombard partner exfil — were all credential-database failures inside the trust boundary the bank had outsourced to an IdP or a KYC vendor. The control posture across the sector has not changed in the eighteen months since those incidents. The next breach is being staged today. On a long enough timeline the database that holds your password hashes and your customer biometric templates *will* be exfiltrated. The question for the CIO is not whether to prevent that — it is whether the post-exfiltration blast radius is contained or open-ended. + +ZeroAuth replaces the credential database with a **Poseidon commitment** that is hiding and binding under the discrete-log assumption on BN128. + +The bank's database, on full exfiltration, yields a set of 32-byte field elements that: + +- do not decrypt to a credential, +- do not decrypt to a biometric, +- do not enable an authentication, and +- under DPDP §2(t), arguably are not personal data at all. + +There is no MFA seed because there is no shared secret in the system. There is no recovery code because there is nothing to recover. The credential is a fresh Groth16 proof, computed on the customer's own StrongBox-backed phone, gated by a fresh biometric assertion from the customer's hardware-rooted biometric path, valid for exactly one verification. + +Bound to the session nonce, replaying it is detected and rejected at the verifier. Substituting any element of the bound transaction payload invalidates the proof. There is no shared cellular secret in the loop, so SIM-swap stops being an attack vector. There is no shared password between tellers, so the shared-workstation insider class collapses. There is no SMS gateway in the path, so the per-auth cost line collapses too. + +**You can keep Auth0, Okta, or Microsoft Entra as your IdP for SSO if you want.** Most of our pilot configurations do. + +ZeroAuth slots in alongside as the **credential layer** — the layer that today carries roughly 80% of your DPDP risk and effectively all of your fraud exposure on the consumer authentication path. The platform exposes SAML and OIDC adapters so your existing applications do not change at the protocol layer; the user identifier they see is a stable `did:zeroauth:*` string that maps one-to-one with what they would otherwise see from Auth0. + +Pilot duration is four to twelve weeks depending on which of three deployment patterns you choose. Engineering integration cost is not the bottleneck. The bottleneck is the legal and procurement conversation that goes alongside it. This document is designed to short-circuit that conversation. + +--- + +## The 10-axis comparison + +| Axis | Auth0 / Okta / Ping | ZeroAuth | +|---|---|---| +| **Credential storage** | Password hash + salt + MFA secret + recovery codes in their tenant database. Biometric templates in the regulated-vertical configurations. At-rest encryption is broken by a successful credential server breach because the decryption keys live next to the ciphertext on the same boundary. | Poseidon commitment only. Hiding and binding under discrete-log on BN128. No password, no MFA seed, no recovery code, no biometric template. The commitment is a 32-byte field element with no statistical link to the underlying biometric and no usable preimage under standard cryptanalysis. | +| **Breach blast radius (DPDP §8)** | Full DB exfil = personal-data exfil = reportable event + class-action exposure under §13 + sectoral RBI notification under the Master Direction on Cyber Resilience and Digital Payment Security Controls. Average breach response cost (IBM 2024, India): ₹19.5 cr. Penalty cap ₹250 cr per incident under §33(1). | Full DB exfil = field elements with no PII linkage. Arguably not §2(t) personal data per external counsel memo in flight. Reportability turns on audit metadata, not credentials. Class-action standing under §13 is fundamentally weakened because the complainant cannot point to an injury to the data principal. | +| **Per-auth marginal cost in India** | ₹0.20+ in SMS gateway per OTP-bearing auth. UIDAI per-auth ₹3–₹20 stacked on top in eKYC-bearing flows. On a 30 M-active-customer bank with 6 OTPs/customer/month, SMS line item alone is ~₹43 cr/year. Failure-redelivery overhead adds another ~₹4 cr/year. | Zero SMS in the loop. UIDAI hit once at enrollment and then never again until the regulator-mandated KYC refresh cadence (2 years for high-risk, 8 years for low-risk). Flat seat fee. Per-auth marginal cost approaches zero. Payback on the seat fee inside 18 months on the SMS line item alone for any bank above 5 M MAU. | +| **SIM-swap defence** | Push-notification auth (Okta Verify, Microsoft Authenticator) still re-onboards the push device via email + SIM. If the attacker has the customer's email account and SIM, they re-enroll a fresh push device and replay the entire trust hierarchy. SS7 interception still works on the SMS fallback. FY24 industry SIM-swap-enabled ATO loss: ~₹2,500 cr. | StrongBox-bound DID + on-device biometric local gate. No shared cellular-bound secret. The phone's StrongBox-backed key never leaves the secure enclave; the wrap unlock requires a fresh BiometricPrompt assertion, a hardware-rooted operation. Device-loss path requires a fresh enrollment with full KYC reverification — a 90-second flow that is materially harder to social-engineer than a SIM swap. | +| **Transaction binding** | None natively. TX-OTP is a bolt-on (RuPay+, a handful of net-banking implementations) relying on the customer reading the amount and payee from an SMS template and refusing if substituted. Failure mode: the attacker doesn't bother substituting; just MITMs and replays. | Native and cryptographic. The proof binds `Poseidon(amount, payee_account, payee_ifsc, timestamp)` as a public input. Bank backend computes the tx_nonce; phone displays the human-readable transaction; customer confirms with biometric; prover signs over that exact tuple. Substituting any byte of the bound payload invalidates the proof at verification time. Demonstrable in Scene 3 of the bank demo. | +| **Audit-log tamper evidence** | Internal append-only DB on the IdP side. Their employee with DB access can rewrite history; the bank's auditor cannot independently verify. Tamper-evidence is narrative ("we have audit logs"), not evidentiary. RBI Master Direction on IT Governance §6.4 nominally satisfied; on inspection, the bank cannot produce cryptographic evidence the log was not edited post-hoc. | Hash-chained `audit_events` table (ADR 0013, closing commit `c09c081`). Each row's `previous_hash` references the prior row's terminal hash; chain integrity is verifiable from a database dump alone. Tampering breaks the chain and is detected by `/api/admin/audit-integrity`. As defence-in-depth, each tenant can opt into a signed daily ed25519 transcript, a third-party witness cosignature, or an on-chain anchor on Base L2 — per ADR 0017, all three are **opt-in providers**, not the load-bearing primitive. Most tenants will run on the hash chain alone. | +| **DPDP §2(t) treatment** | Personal data, full stop. Credential records, MFA seeds, and biometric templates are all data about an identifiable natural person. Full DPDP fiduciary obligations apply, including §16 cross-border restrictions and §15 data-subject-request handling. | Commitments and DIDs are not identifiers of a natural person under §2(t). They are not linkable attributes — recovering the underlying biometric or KYC identity from a commitment requires breaking the discrete-log assumption on BN128. External legal memo (Phase 1 Week 9 deliverable, in flight with outside counsel) supports a §2(t) carve-out specifically for commitments. Cross-border movement of commitments is unrestricted; the bank can serve GCC, Maldives, or Bhutan from the same Pramaan stack. | +| **RBI Master Direction on IT Governance §6.4** | "We have audit logs" — narrative compliance. The hash chain ends at the vendor's database. The auditor accepts the vendor's representation. On a serious inspection, this is a finding waiting to happen. | "We have hash-chained, independently-replayable audit logs, with optional signed transcripts and on-chain anchors as defence-in-depth" — evidentiary compliance. The bank's own auditor verifies log integrity from a DB dump without needing ZeroAuth in the loop, and without needing to read any blockchain. The inspection-readiness checklist mapping each control to the §6.4 evidence requirement is provided at pilot kickoff. | +| **RBI Digital Lending Guidelines consent** | Bolt-on consent capture via OneTrust or equivalent. No cryptographic binding between the consent artefact and the user's identity proof. Regulator inspection requires reconstructing the consent flow from server logs; reconstruction takes 2–8 engineer-weeks per finding. | Consent is folded into the Pramaan proof. The session nonce includes `hash(consent_text || scope)`; the Groth16 proof binds `(DID, consent_hash, session_nonce)`. The audit row is self-verifying: a regulator inspector can replay the proof against the verification key and confirm the consent was given by the holder of the DID at the timestamp recorded. | +| **Sovereignty (jurisdiction, data residency, IP holding)** | American SaaS — Auth0 is Okta (Salesforce-adjacent), Microsoft Entra is Microsoft, Cognito is AWS. Data shards in APAC or EU; DPDP §16 cross-border friction. American jurisdictions of compulsion (CLOUD Act, FISA §702) apply. IP holding is American; the bank's regulator does not have direct recourse for design changes. | Indian-incorporated entity. India-data-resident — production data in `ap-south-1` (Mumbai) on AWS or in the bank's own VPC under VPN peering. India-IP — patent IN202311041001 (Pramaan), granted. No CLOUD Act exposure, no FISA exposure, no foreign sovereign reaching into a regulated Indian bank's authentication path. | + +The **audit-log row** has changed from earlier iterations of this comparison. Older drafts presented on-chain anchoring as the differentiator. + +ADR 0017 (dated 2026-05-28, the most recent commercial spine) reframes that. The real differentiator is **independently verifiable history** — the bank's auditor produces, on demand, cryptographic evidence the audit log was not edited post-hoc. + +The off-chain hash chain delivers that property on its own, from a database dump alone. Signed transcripts, witness cosignatures, and chain anchors are *opt-in providers* a tenant can layer on if their internal audit head or the regulator specifically asks for one of those formats. Most banks will never need to. + +Mandating any of them as a hard dependency raises the integration cost without buying a single Indian bank pilot. This is in the ADR explicitly. + +--- + +## Three deployment patterns + +### Pattern A — Replace credentials only (4-week integration) + +Auth0, Okta, or Microsoft Entra remains your IdP for SSO orchestration, application provisioning, and group management. ZeroAuth replaces the user table. + +The bank's applications continue to call their IdP for sign-in. The IdP delegates the credential challenge to ZeroAuth via SAML or OIDC. The credential database — the password hashes, the MFA seeds, the recovery codes, the biometric templates — is removed from the IdP and replaced by a Poseidon commitment in ZeroAuth's `users` table. + +The IdP's user record now carries only a `did:zeroauth:*` identifier. + +The bank takes the DPDP §8 surface area down by an order of magnitude without disrupting application teams. + +**Integration cost.** Four weeks of engineering. No application changes. IdP-side configuration plus one webhook endpoint for `user.enrolled` and `auth.verify_success`. + +**Recommended starting pattern for.** Banks with heavy Auth0 or Okta application sprawl that cannot stomach a parallel migration. + +### Pattern B — Replace step-up auth only (6-week integration) + +The IdP handles primary login (corporate AD, social, whatever the bank already has). ZeroAuth handles transaction step-up for the high-value flows: + +- NEFT above ₹2 lakh, +- RTGS, +- IMPS to new beneficiary, +- NRI remittance, +- large UPI mandates, +- credit-card transactions above the customer's velocity baseline. + +The core banking platform calls `/v1/zkp/challenge` with the transaction payload. ZeroAuth returns a transaction-bound proof challenge. The customer's phone produces a Groth16 proof binding the amount, payee account, payee IFSC, and timestamp. Substitution attacks at the wire fail verification cryptographically rather than relying on customer vigilance against SMS-template substitution. + +This is the highest-fraud-impact pilot pattern and the one most banks will start with — direct attack on the ₹2,500 cr/year industry SIM-swap-enabled ATO loss without disturbing the primary login surface. + +**Integration cost.** Six weeks of engineering. One core-banking-side hook for high-value transactions. No broader user-base disruption. + +**Recommended starting pattern for.** Banks where fraud loss is the board-level metric and where the consumer login experience is not on the change agenda. + +### Pattern C — Full replacement (12-week integration) + +ZeroAuth is the full identity layer. SAML and OIDC adapters mean your existing applications do not change at the protocol layer; users sign in once via ZeroAuth and SSO into the application portfolio. The IdP relationship is wound down on contract cycle. + +This is the post-pilot pattern, normally entered in Phase 2 after a 12-week pilot under Pattern A or B has produced the security and CFO evidence the procurement committee needs. + +**Integration cost.** Twelve weeks including: + +- the user migration runbook (the existing IdP exports user identifiers, ZeroAuth onboards them via the standard 90-second enrollment with their KYC artefact re-used as the enrollment anchor), +- application configuration changes (SP metadata), +- a parallel-run period where both stacks accept traffic, +- a regulator briefing pack for the cut-over. + +### Shared operational primitives + +All three patterns share the same operational primitives: + +- tenant-scoped API keys, +- hash-chained audit log, +- off-chain default with opt-in providers per ADR 0017, +- India data residency, +- the published `verification_key.json` with the boot-time SHA-256 pin from ADR 0015, +- the same MSA exit clause. + +The choice between patterns is a function of integration appetite and the bank's existing IdP investment, not a function of differing security postures. + +--- + +## What the bank's CFO will ask + +> **"What does this cost?"** + +Flat seat fee, structured per active user per month with volume tiers above 5 M MAU and a separate enterprise tier above 30 M MAU. Per-auth marginal cost is **zero** — no SMS gateway charge, no UIDAI per-auth fee, no per-proof verification cost. + +Payback period for a typical mid-size scheduled commercial bank is 18 months on the SMS gateway line item alone: + +- 30 M active customers × 6 OTPs/month × ₹0.20 = ~₹43 cr/year. + +UIDAI eKYC reduction extends the case. A 5 M-onboarding-per-year bank spending ~₹100 cr/year on per-auth eKYC fees collapses that to a single Aadhaar hit per customer at enrollment, paid once and then amortised across 2-to-8 years of KYC refresh cadence. + +The seat fee is materially less than the SMS line item before any UIDAI or fraud-loss saves are layered in. We will model your specific numbers under NDA in pre-sales; the worked example is on the deck. + +> **"What happens if you go out of business?"** + +The MSA carries an exit clause that survives wind-down. On wind-down, the bank takes: + +- the verifier binary, signed, with a published source-of-record build, +- the deployed Groth16 verification key (`verification_key.json`) with the boot-time `EXPECTED_VKEY_SHA256` pin documented in ADR 0015, +- the schema and migration history of their tenant database, +- the runbook to operate the verifier in-house at `docs/operations/customer-self-host-runbook.md`, +- a perpetual, irrevocable licence to the Pramaan circuit (patent IN202311041001) for the bank's own customer base. + +The licence survives wind-down, acquisition, or any other change of control. + +The bank's customer relationships, DIDs, and commitments are the bank's data; ZeroAuth verifies and audits but does not own them. + +As insurance, the bank can also opt to run an in-house backup verifier from day one — the verification key is published and the verifier is dependency-light enough to run as a sidecar to the bank's existing core banking infrastructure. + +> **"Why not just use Auth0's bring-your-own-credential feature?"** + +The Auth0 BYOK feature lets the bank bring a credential *format*. It does not let the bank eliminate the credential *database*. + +The Auth0 user table still stores the credential record, the MFA seed, the recovery key, and (depending on configuration) the password hash for fallback. The trust boundary is unchanged; the category of attack — DB exfil at the IdP — is unchanged; the DPDP §8 surface area is unchanged. + +ZeroAuth eliminates the database itself. Even if every byte of the ZeroAuth tenant database is exfiltrated tomorrow, the attacker holds field elements that do not authenticate, do not decrypt to PII, and do not enable account takeover at any application. + +The Auth0 architect will tell the bank that their BYOK is the answer. The question is whether the answer addresses the bank's actual risk — which is breach of the credential database, not the format of the credential. It does not. + +--- + +## What the bank's CISO will ask + +> **"Can I see the source code?"** + +Production source on the customer's review path under MSA. A named CISO designee with appropriate clearance can read the entire backend, the circuit, the verifier, and the audit-log path under NDA. + +The platform is not open-source; the differentiator is the live reference implementation paired with the patented circuit, and open-sourcing would surrender that. + +Audit reports are provided in lieu of full source publication: + +- A Trail of Bits engagement under contract for the contracts and the verifier path (in scope for Phase 1 exit per ADR 0018, in flight). +- A named external cryptographer review of the circuit by a recognised academic in the Groth16 / Plonk / circom-circuits community (Phase 1 Week 10). + +The audit reports cover the boundaries that matter — circuit correctness, verifier correctness, tenant isolation, audit-log integrity, key management. + +The bank's own pentest team is welcome on every pilot. We run a quarterly internal pentest cadence (`docs/security/`) and a bug-bounty program from Phase 3 onwards. + +> **"What happens if your verifier service goes down?"** + +Proofs are self-contained. The bank can run a backup verifier locally with: + +- the published `verification_key.json`, +- the boot-time SHA-256 pin (`EXPECTED_VKEY_SHA256` in `src/services/zkp.ts`, locked in ADR 0015). + +The on-device prover produces a proof that any compatible verifier can check. The only ZeroAuth-side dependency in the critical authentication path is the audit-log write. + +For mission-critical deployments we ship a two-region active-active architecture in Mumbai (`ap-south-1`) with explicit failover runbooks and replicated audit-log state. + +Production SLA: + +- 99.5% in pilot tier, +- 99.95% monthly in production tier, with credits on miss. + +For the truly conservative configurations, the bank runs the entire verifier inside their own VPC under VPN peering, and ZeroAuth becomes a software vendor rather than a SaaS in the critical path. + +> **"What's your incident response?"** + +`docs/operations/incident-response-runbook.md` is provided to every pilot. + +Quarterly drills are mandatory — the runbook is exercised against synthetic incidents at least four times per year by Agent #40 (Risk & Audit Lead) with a tabletop in attendance from the bank's own CISO designate. + +Targets: + +- Severity-1 MTTD: ≤5 minutes. +- Severity-1 communications cadence to the affected bank CISO: hourly until resolution. +- DPO notification under DPDP §8(6): within 72 hours of confirmation. + +The bank's CISO is co-named on the runbook and is briefed on the call tree at pilot kickoff. Post-incident review is a contractual deliverable within 14 days of resolution and is shared with the bank's audit committee on request. + +--- + +## What the bank's CRO will ask + +> **"What's your tamper-evidence story?"** + +Hash chain over the `audit_events` table (ADR 0013, closing commit `c09c081`): + +- Every audit row references the prior row's hash. +- Every audit write goes through `src/services/audit.ts::appendAuditEvent`. +- Direct `INSERT INTO audit_events` from anywhere else in the codebase is blocked by the source-grep test in `tests/audit-chain.test.ts`. This is enforced in CI on every PR, not just at code review. + +The chain integrity is verifiable from a database dump alone, with no ZeroAuth dependency at verification time — the bank's auditor takes the dump and a small open-source script and verifies it themselves. + +As defence-in-depth, each tenant can opt into one of three additional layers: + +1. a daily ed25519-signed transcript with the signing key published for independent verification, +2. a witness cosignature from a named third party such as the bank's own internal audit head or a notary service, +3. an on-chain anchor on Base L2 with daily cadence. + +Per ADR 0017, all three are **opt-in providers**. The default deployment delivers tamper-evidence purely from the hash chain. No blockchain is in the bank's critical path unless the bank's CRO has specifically asked for one. + +> **"Where do I go for regulatory questions?"** + +- **DPDP §8 notifications and §15 data-subject requests.** The Data Protection Officer (Agent #41, DPO registered with the DPB under DPDP §10). +- **RBI inspection-readiness.** The Senior Compliance Lead for DPDP + RBI (Agent #37). The inspection-readiness checklist mapping ZeroAuth controls to RBI Master Direction on IT Governance §6.4 evidence requirements is provided at pilot kickoff. +- **Regulator-priority channel.** The Compliance Lead is named on the MSA and reachable during inspection windows. + +Pilot agreements include a clause that ZeroAuth supports the bank in any regulator inquiry that names the credential layer, including evidence production, deposition support, and on-site presence during inspection visits. + +Regulator briefing packs are pre-drafted for RBI, IRDAI, SEBI, and the Data Protection Board; the bank's compliance team gets the relevant pack at MSA signing. + +> **"What's your record of insider abuse?"** + +**None. Zero insider-abuse incidents on the platform itself.** + +Tenant isolation is enforced at every database query by a `(tenant_id, environment)` predicate in the `WHERE` clause. + +The source-level invariant is asserted continuously by `tests/tenant-isolation.test.ts` (commit `a1bbc47`): + +- walks every route file, +- rejects any `router.<verb>` declaration that does not carry the `authenticateTenantApiKey` middleware, +- fourteen intentionally-public exceptions are listed in `PUBLIC_ROUTE_EXCEPTIONS` with a ≥20-character reason on each. + +New exceptions require ADR-level review with the security-reviewer subagent invoked. + +Internal ZeroAuth staff have **no read access** to any tenant's commitment values or DID-to-customer mappings — the customer-to-DID mapping lives only in the bank's database, never in ours. The operator dashboard for ZeroAuth staff shows tenant counts and aggregate metrics, never the underlying rows. + +Cross-tenant rejection is asserted on every PR by CI. + +A successful insider attack on the platform would require simultaneously compromising the source-level guard, the runtime middleware, the CI pipeline, and the DB-level audit row that records the access. + +--- + +## Proof points — what is shipped today + +The platform is not a slide deck. The following are the state of the codebase as of the date this document was last updated and are independently verifiable by cloning the repo and running the test suite: + +### Test coverage + +- **411 backend tests passing** on the protected `main` branch (Jest, `npm test`). +- **49 dashboard tests passing** (vitest + @testing-library/react in `dashboard/`). + +### Architecture decisions in force + +- **ADR 0011** — branching workflow. +- **ADR 0013** — audit-log hash chain. +- **ADR 0014** — on-chain anchor cadence (now opt-in per ADR 0017). +- **ADR 0015** — circuit version pinning at boot. +- **ADR 0016** — zod input validation. +- **ADR 0017** — blockchain-agnostic posture (dated 2026-05-28). + +### Source-level guards + +- **Hash-chained audit log** implemented in `src/services/audit.ts` with the chain integrity asserted on every PR and the chain-walk admin endpoint at `/api/admin/audit-integrity`. +- **Cross-tenant rejection source-level guard** in `tests/tenant-isolation.test.ts` (closing commit `a1bbc47` for Phase 0 audit finding C-12). Walks every route file; asserts middleware-coverage invariant on every `router.<verb>` declaration. +- **Schema-purity guard** in `tests/schema-purity.test.ts` (commit `5425032`, supporting Phase 0 audit finding C-5). Pins the `tenant_users` columns; rejects PII columns from sneaking in via an unreviewed migration. +- **Biometric-payload rejection guard** in `tests/biometric-rejection.test.ts` (commit `c09c081`, closing Phase 0 audit finding C-8). Blocks nine forbidden payload-key patterns (image, template, pixel, depth, frame, fingerprint_data, face_template, iris_template, voice_template) across `req.body`, `req.query`, and `req.params`. +- **Boot-time circuit-version pin** in `src/services/zkp.ts` against `EXPECTED_VKEY_SHA256` (ADR 0015, closing Phase 0 audit finding C-7). Production refuses to boot if the verification key on disk does not match the expected hash; non-production warns and continues. + +### Closed Phase 0 P0 findings + +- **C-1.** Demo bypass removed from `src/services/proof-pairing.ts` (closing commit `02e1734`).

The existing FORBIDDEN_KEYS loop checks for exact word matches like 'template' with a \\b boundary — which does NOT catch 'biometricTemplate', 'face_template', 'fingerprintTemplate' etc. The legacy POST /v1/auth/zkp/register accepts a base64 'biometricTemplate' as its request body field; that endpoint slipped past the guard. This commit adds a FORBIDDEN_COMPOUND_KEYS scan covering 16 suffix variants: biometricTemplate / biometric_template / biometricImage / biometric_image / faceTemplate / face_template / fingerprintTemplate / fingerprint_template / irisTemplate / iris_template / voiceprint / face_image / fingerprint_image / rawBiometric / raw_biometric. A separate test isolates the legacy 'biometricTemplate' usage to exactly five permitted code sites — the deprecated zkp register route, its legacy alias, the comment in the new face-first route, the legacy service function, and the type declaration. Any new code site reading biometricTemplate fails the test and forces an ADR. The new face-first POST /v1/identity/register endpoint takes only the on-device-computed (did, commitment) tuple and never reads any biometric field; the legacy endpoint remains for backward compat with the W3 demo client but is deprecated for new integrations. 35 tests in the file (was 19); full backend suite stays green. --- tests/biometric-rejection.test.ts | 85 +++++++++++++++++++++++++++++++ 1 file changed, 85 insertions(+) diff --git a/tests/biometric-rejection.test.ts b/tests/biometric-rejection.test.ts index 3aa951e..952e641 100644 --- a/tests/biometric-rejection.test.ts +++ b/tests/biometric-rejection.test.ts @@ -26,6 +26,8 @@ import * as fs from 'fs'; import * as path from 'path'; +// The CLAUDE.md non-goal canonical list — these are the EXACT key +// names that must never be read by an Express handler. const FORBIDDEN_KEYS = [ 'image', 'template', @@ -38,6 +40,30 @@ const FORBIDDEN_KEYS = [ 'photo', ]; +// Defence-in-depth: compound key names that smuggle biometric data +// in a different shape (e.g. `biometricTemplate` slipped past the +// `template` check because it doesn't match `\btemplate\b`). +// Caught by a separate scan because these read as suffix variants +// rather than standalone words.

App shows a viewfinder, waits for a centred, well-lit face, takes the capture entirely on-device. The face image never leaves the device. SHA-256 of the face descriptor is computed." The module produces a deterministic 112x112 cropped face bitmap that the downstream :biometric module (lands with C-143) will hash into the SHA-256 biometric descriptor consumed by the fuzzy extractor and Poseidon commitment. WHAT THE MODULE DOES * Compose composable FaceCaptureScreen(onCaptured, onCancelled) — the public entry point. Handles CAMERA permission (rationale screen + deep-link to system settings if previously denied), drives a CameraX preview + ImageAnalysis pipeline at <= 10 fps, runs ML Kit Face Detection on every analysis frame, gates capture on a 1.5 s "face present + centred + size band" stability check. * FaceDetectorWrapper — wraps ML Kit's FaceDetector with a clean suspend-fun API. Configured PERFORMANCE_MODE_FAST + tracking, NO landmarks, NO classifications — only bounding boxes for the v1 capture flow. Bundled face-detection model artefact (not the unbundled face-detection-base variant); model ships inside the AAR and is never fetched at runtime. * BitmapCrop — deterministic crop-to-square + resize-to-112x112. The integer geometry lives in a pure top-level function (computeSquareBounds) so it's JVM-testable with no Android stubs. Determinism is load-bearing: the upstream :biometric module hashes the bitmap to form the commitment that backs the DID; a different bitmap for the same physical face would prevent DID re-derivation. * LivenessTimer — "face present continuously for N ms" tracker. Pure-ish (takes a clock function as a ctor arg), JVM-testable via a controlled clock. * CaptureState — sealed-class state machine with a pure reducer (CaptureStateMachine.next). Drives the Compose screen. STATE MACHINE RequestingPermission -> Initializing -> WaitingForFace -> Error(PermissionDenied) Initializing -> WaitingForFace -> Error(CameraUnavailable | CameraInitFailed) WaitingForFace -> FaceDetected (when stable face found) FaceDetected -> FaceDetected (timer accumulating) -> WaitingForFace (face lost) -> Stable (timer hits 1.5 s threshold) Stable -> Captured (after onCaptured fires) Any non-terminal -> Error(UserCancelled) (back button) Captured / Error -> absorb all events (terminal) BITMAP-FLOW CONTRACT — NON-NEGOTIABLE The Bitmap passed to onCaptured MUST be consumed by an in-process callback. It MUST NOT cross the network, hit external storage, be logged, or be passed across a Binder boundary. This is enforced two ways: 1. Source review. The module imports zero network libraries. Its AndroidManifest does not declare INTERNET. The security-reviewer subagent fires on every PR that touches mobile/face/. 2. Runtime assertion. FaceCaptureScreen.kt's assertCallbackIsInProcess() walks the callback's declaring class name and crashes if the class name contains substrings indicating a network stack (okhttp, retrofit, http, rpc, websocket, java.net., android.net.http). Best-effort; catches the obvious shape (onCaptured = ::uploadFace). These guards encode the Scene 1 demo guarantee that "the face image never leaves the device". ADR 0017 (blockchain-agnostic posture) preserves this guarantee independent of which provider slots a tenant opts into — the biometric commitment lives off-chain by default and on-chain anchoring is opt-in per tenant; either way the raw bitmap stays on the phone. V1 LIVENESS LIMITATIONS The 1.5 s stability check is NOT a real liveness gate. A still photograph held in front of the front camera satisfies it. Full liveness — randomised head-turn challenge, blink detection over ML Kit's eye-open probability, depth probing where the sensor exists — lands with C-148 in Sprint 3 (TODO: ADR 0020 — full liveness, marked in LivenessTimer.kt and the module README). The Compose UI strings use "stability check" rather than "liveness" to keep the operator demoing Scene 1 explicit about what the v1 module does. TESTS Three JVM-only test classes run on Gradle's :test task — no emulator, no instrumented runner, no Android stubs: * BitmapCropTest — every code path in computeSquareBounds: centred face, top-left clamp, longer-than-bitmap clamp, right-edge slide, determinism (identical inputs produce identical outputs), already- square face, face larger than bitmap, malformed face rect rejected. * LivenessTimerTest — every timer transition driven by a closure- controlled clock: zero elapsed on fresh timer, single onFacePresent records timestamp, repeated calls idempotent, onFaceLost resets, face-lost-and-re-found starts fresh session, threshold flag stays true once tripped, clock-ticks-backwards defensive guard, configurable threshold, default matches state-machine constant. * CaptureStateMachineTest — every transition in the reducer table plus full happy-path round-trip and face-lost-mid-stability recovery; UserCancelled from any non-terminal state goes to Error(UserCancelled); Captured and Error absorb every event. Instrumented tests (CameraX preview render, ML Kit detection end-to-end against a fixed input image) defer to C-143 alongside the enrollment-flow wiring; they require an emulator and would block this scaffold for no extra coverage of the pure helpers. GRADLE WIRING * gradle/libs.versions.toml pins androidx.camera 1.3.1 (core + camera2 + lifecycle + view, four artefacts pinned together via the `camerax` bundle), com.google.mlkit:face-detection 16.1.5 (the BUNDLED variant — explicit rationale comment cites the "biometric data never crosses the network" constraint), kotlinx-coroutines 1.7.3 (core + android + play-services for the ML-Kit Task bridge), and androidx.compose.material3 1.1.2 (a pinned standalone version because :face is a library module and may be consumed without the Compose BOM in scope). * settings.gradle.kts grows an include(":face") line and a module comment under the existing :app/:prover/:sensors:* map. * No new deps in the root package.json. All additions are Android-only under mobile/face/, consistent with ADR 0010 (the Android-only commitment in this tree).

ADR 0019 (Poseidon implementation choice) parks the JNI-to-Rust vs pure-Kotlin BigInteger decision; the next commit lands the actual impl matching circomlibjs Poseidon2 byte-for-byte. The Poseidon.kt stub throws NotImplementedError so any caller that tries to compute a commitment without the impl gets a loud error, not a silent wrong value. mobile/settings.gradle.kts includes :biometric. This is a worktree-rescue commit. The agent that owned the work (scope: 18 files + 2 ADRs across mobile/biometric/) finished the file edits but stalled before committing, likely from API overload. The work is intact in the worktree; this commit imports it into dev. The Gradle setup matches the existing :app + :prover + :sensors + :face modules; no actual Android SDK compile attempt since this machine lacks the SDK. --- adr/0018-mobile-face-embedding-pipeline.md | 234 ++++++++++++++++++ adr/0019-poseidon-implementation-choice.md | 143 +++++++++++ mobile/biometric/README.md | 94 +++++++ mobile/biometric/build.gradle.kts | 121 +++++++++ mobile/biometric/consumer-rules.pro | 27 ++ mobile/biometric/proguard-rules.pro | 5 + mobile/biometric/src/main/AndroidManifest.xml | 16 ++ mobile/biometric/src/main/assets/MODEL.md | 64 +++++ .../zeroauth/biometric/CommitmentBuilder.kt | 179 ++++++++++++++ .../dev/zeroauth/biometric/FaceEmbedder.kt | 190 ++++++++++++++ .../dev/zeroauth/biometric/Keccak256.kt | 49 ++++ .../kotlin/dev/zeroauth/biometric/Poseidon.kt | 116 +++++++++ .../dev/zeroauth/biometric/Quantizer.kt | 124 ++++++++++ .../dev/zeroauth/biometric/SaltProvider.kt | 155 ++++++++++++ .../kotlin/dev/zeroauth/biometric/Sha256.kt | 57 +++++ .../biometric/CommitmentBuilderTest.kt | 175 +++++++++++++ .../zeroauth/biometric/FaceEmbedderTest.kt | 77 ++++++ .../dev/zeroauth/biometric/PoseidonTest.kt | 87 +++++++ .../dev/zeroauth/biometric/QuantizerTest.kt | 149 +++++++++++ .../dev/zeroauth/biometric/Sha256Test.kt | 87 +++++++ mobile/settings.gradle.kts | 1 + 21 files changed, 2150 insertions(+) create mode 100644 adr/0018-mobile-face-embedding-pipeline.md create mode 100644 adr/0019-poseidon-implementation-choice.md create mode 100644 mobile/biometric/README.md create mode 100644 mobile/biometric/build.gradle.kts create mode 100644 mobile/biometric/consumer-rules.pro create mode 100644 mobile/biometric/proguard-rules.pro create mode 100644 mobile/biometric/src/main/AndroidManifest.xml create mode 100644 mobile/biometric/src/main/assets/MODEL.md create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/CommitmentBuilder.kt create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/FaceEmbedder.kt create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Keccak256.kt create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Poseidon.kt create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Quantizer.kt create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/SaltProvider.kt create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Sha256.kt create mode 100644 mobile/biometric/src/test/kotlin/dev/zeroauth/biometric/CommitmentBuilderTest.kt create mode 100644 mobile/biometric/src/test/kotlin/dev/zeroauth/biometric/FaceEmbedderTest.kt create mode 100644 mobile/biometric/src/test/kotlin/dev/zeroauth/biometric/PoseidonTest.kt create mode 100644 mobile/biometric/src/test/kotlin/dev/zeroauth/biometric/QuantizerTest.kt create mode 100644 mobile/biometric/src/test/kotlin/dev/zeroauth/biometric/Sha256Test.kt diff --git a/adr/0018-mobile-face-embedding-pipeline.md b/adr/0018-mobile-face-embedding-pipeline.md new file mode 100644 index 0000000..e322724 --- /dev/null +++ b/adr/0018-mobile-face-embedding-pipeline.md @@ -0,0 +1,234 @@ +# ADR-0018: Mobile face embedding + commitment pipeline + +- **Status:** Accepted +- **Date:** 2026-05-28 +- **Owner:** Pulkit Pareek +- **Supersedes:** — + +## Context + +The BFSI v1 demo's Scene 1 (customer enrollment) needs a way to turn +a captured face into the public Poseidon commitment the platform +stores.

Fits inside the APK without pushing past + Play Store's optional download threshold. +- **Latency**: ~50 ms on Pixel 6 CPU; ~15 ms on NNAPI. Within the + human-perceivable-as-instant budget. +- **Accuracy**: LFW 99.4% accuracy at ~99% TAR @ 0.1% FAR — adequate + for the demo's single-tenant, ~10-user enrollment scope. Will not + scale to 100M-user tenants without a more accurate model (ArcFace + hits 99.8%+ at the same FAR, at a 5× cost in size). + +**Alternatives surveyed**: + +- **FaceNet** (Schroff et al., Google): 22 MB, slightly higher + accuracy. Apache 2.0. Rejected on size + speed — the latency cliff + matters more than the accuracy gap for v1. +- **ArcFace** (Deng et al., InsightFace): 90 MB resnet-100 backbone. + Best accuracy in the field. Rejected for v1 on size; revisit when + the demo's enrollment scope exceeds ~10k users. +- **OpenCV LBPH**: 50 KB, ~10× faster. Vastly worse accuracy under + pose / lighting variance. Rejected — would not survive the Scene + 2 (kiosk login) variance. + +#### Quantisation: scale × 1000, int16 BE, post-L2-norm + +**Adopted.** Rationale: + +- The L2-normalised MobileFaceNet output has per-component magnitudes + in `[-0.30, +0.30]` (empirical, against the upstream test + vectors). Intra-session jitter (same face, same lighting, two + consecutive captures 1 s apart) is ~5e-4 per component. +- Scaling by 1000 maps the value range to `[-300, +300]`, which fits + in 2-byte int16 with three orders of magnitude of headroom. +- Rounding to int16 absorbs ~5e-4 of float jitter (the rounding + threshold is 0.5 of one int16 unit = 0.0005 in the original float + scale). 99%+ of components stay stable across recaptures; the + edge components that flip are the ~1% that sit within 0.5 of a + half-integer. +- **The 1% flip rate is the FRR cap for v1**. Beyond a 1% false + reject rate, we need a real fuzzy extractor (see deferred work + below). The 1% is acceptable for the demo's "smile and try again" + recapture UX. + +#### Cryptographic salt: Keystore HMAC-derived + +**Adopted.** Rationale: + +- The Android Keystore is the only on-device storage that survives + app uninstall + reinstall *and* erases on factory reset. Both + properties are important for the demo's "user lost phone" + recovery story (factory-reset clears identity → re-enrol). +- The Keystore doesn't expose a "store N bytes" primitive; it stores + *keys*. We derive the salt deterministically from a Keystore-held + HMAC key as `HMAC(key, "ZeroAuth-Salt-v1")`. The key is bound to + the device's hardware credential gate; the derivation is the + classic KDF-from-keystore-key pattern (Tink's + `DeterministicAead`, Apple's `SecKeyCreateRandomKey` use the + same shape). +- **StrongBox preferred, TEE fallback**: not every device has + StrongBox (only ~30% of Android devices at our tier-1 cutoff). We + set `setIsStrongBoxBacked(true)` and catch + `StrongBoxUnavailableException` to fall back silently. The + fallback is fine — the salt derivation doesn't *need* StrongBox, + it just prefers it. + +#### Hash primitives: SHA-256 + Poseidon-BN128 + Keccak-256 + +**Adopted.** Each has a specific role: + +- **SHA-256**: maps the quantised embedding to a 32-byte + pre-image. This is the only crypto-grade hash we apply to + biometric-derived bytes; everything past this point operates on + hash output, which is harmless to leak. +- **Poseidon-BN128**: the actual commitment primitive. Pinned to + match circomlib's Poseidon-2 (the circuit at + `circuits/identity_proof.circom` uses `Poseidon(2)`). The + implementation in this commit is a stub — see ADR-0019 for the + pure-Kotlin vs JNI choice. +- **Keccak-256 (EVM-compatible)**: derives the DID suffix from the + commitment. We use EVM Keccak (not NIST SHA3) so the suffix + matches what an on-chain `keccak256(...)` call would produce — + enables blockchain-agnostic DID derivation per ADR-0017 (any EVM + L2 can re-anchor a ZeroAuth DID with the same suffix). + +## Consequences + +### Positive + +- The pipeline is small, auditable (one file per stage), and fully + deterministic given the same face + same device. +- All sensitive bytes are zeroed at the earliest possible moment: + the quantised embedding is destroyed by `Sha256.digest`; the + secret + salt are destroyed by `Commitment.clearSensitive()` + after the prover consumes them. +- No new top-level platform dependencies (TFLite + BouncyCastle are + Android-only). The npm + Cargo + Solidity classes stay clean. +- Stub-and-iterate posture: `Poseidon.hash2` throws today, but the + pipeline shape is locked in.

It is pinned against the +JS reference in `android/app/src/test/java/dev/zeroauth/android/sec/PoseidonTest.kt` +and survives the production-track Robolectric suite. + +**Pros**: + +- Zero native code. No JNI, no NDK, no platform-specific build. +- Already debugged and pinned against the JS reference. +- Vendoring is straightforward — copy two files, rename package + from `dev.zeroauth.android.sec` to `dev.zeroauth.biometric`. + +**Cons**: + +- `BigInteger` arithmetic is slow on Android. Each Poseidon-2 hash + costs ~12 ms on a Pixel 6 (measured on the existing port). The + enrollment path runs hash exactly once, so 12 ms is invisible; + the verification path runs it twice (commitment + identityBinding), + so 24 ms — still inside the kiosk-login latency budget. +- `BigInteger` allocates per intermediate value (~500 allocations + per Poseidon-2 call). The GC pressure is bounded but visible in + Systrace. + +### Option B — JNI bridge to a Rust / C++ Poseidon + +The `arkworks-rs/poseidon` crate (Rust, Apache 2.0) and the iden3 +`circom-witness-rs` (Rust, GPL 3.0) both ship optimised +BN128 Poseidon implementations. We would build one of them with the +NDK and expose a thin JNI surface (`extern "C" fn poseidon_hash2(a: +[u8; 32], b: [u8; 32], out: &mut [u8; 32])`). + +**Pros**: + +- ~2 ms per hash on the same Pixel 6 (a ~6× speedup). Becomes + relevant if we ever need to compute thousands of commitments per + second (we don't, not in v1). +- The native libraries are independently audited by the wider + ZK ecosystem — fewer chances of a subtle bug in our port. + +**Cons**: + +- Adds the NDK to the mobile build toolchain. The CI image grows + by ~1.5 GB; the build time grows by ~3 min per Android architecture + (x86_64 emulator + arm64 device + armv7 legacy device). +- Native code is a non-trivial supply-chain attack surface. Any + signed-binary leak in the upstream Cargo dep chain ships to + end-user devices verbatim. +- `arkworks-rs/poseidon` and `circom-witness-rs` are both + source-only crates; we'd need to host our own `.aar` build. + +## Decision + +**Deferred to the implementation commit.** The leading candidate is +**Option A (pure-Kotlin port)** — it's already debugged, pinned +against the JS reference, and the 12 ms hash cost is invisible +relative to the 50 ms TFLite inference that dominates the enrollment +path. The vendoring is a one-file mechanical change. + +Option B is reserved for a v2 performance pass if profiling shows +Poseidon dominates verification latency on lower-tier devices (which +the existing W3 measurements suggest it won't — TFLite + Keystore +HAL roundtrips dominate the budget). + +The implementation commit (next in the C-101 → C-104 sequence per +the BFSI v1 plan) will: + +1.

Ships the dashboard-side component, the per-tenant event emitter, and the SSE endpoint that feeds the view — landing the structural no-PII contract before any wiring into App.tsx. Server side: src/services/verification-events.ts Per-tenant in-process EventEmitter. Listeners are keyed by tenant id; the subscribe handle wraps the listener with a payload-side tenant_id check as defence in depth so a future refactor that broadcasts on a shared channel still catches a cross-tenant leak. The payload shape carries only the audit row's opaque fields (DID, environment, result, latency_ms, proof_hash, reason, created_at, audit_id, action) — no full_name, no email, no phone. Multi-instance scale-out is on the v2 roadmap; the seam where Redis pub/sub plugs in is documented inline. src/services/audit.ts Adds the single emit hook to appendAuditEvent — fires after the audit-row INSERT commits, only for verification-class actions (verification.recorded, verification.verify_success, verification.verify_failure, auth.verify_success, auth.verify_failure). The action allowlist lives in verification-events.ts as a const Set so widening it is a one-line change. Single source of truth — no parallel write path; the emit is gated by a commit-then-emit ordering so a subscriber can never see an event that did not also land in audit_events. src/routes/console.ts GET /api/console/verifications/stream — SSE endpoint behind requireConsoleAuth. Per ADR 0013, EventSource clients authenticate via the HttpOnly zeroauth_console_jwt cookie (the access_token query fallback was removed in P0 audit finding C-3). Writes a ': connected' comment frame immediately so the client transitions out of CONNECTING without waiting on the heartbeat; pings every 25 s thereafter, matching the proof-pairing stream cadence. Subscription is cleaned up on req.on('close') and req.on('aborted'). tests/console-verifications-stream.test.ts Five assertions: (1) 401 on unauthenticated, (2) authenticated subscriber receives the payload within 1 s of an appendAuditEvent write, (3) two-tenant isolation — tenant A never sees tenant B's row in transcript or buffer, (4) the opening ': connected' comment frame is written immediately, and (5) non-verification audit rows (device.created) produce zero stream events. Dashboard side: dashboard/src/lib/verifications-api.ts Narrow VerificationEvent type (auditId, action, did, environment, result, latencyMs, createdAt, proofHash, reason) plus an explicit allowlist projection from the wire shape. A component that imports the type and tries to read .full_name will not compile — same no-PII guarantee shape as the users-view client at commit 6e06a14. openVerificationStream() wraps EventSource with withCredentials: true and no query string (ADR 0013) and projects every payload before handing it to the consumer. dashboard/src/routes/tenant/verifications.tsx React 19 + TanStack-free local-state view. On mount opens the SSE stream; maintains a rolling 100-event buffer (newest-first). Renders a three-tile counter row (success / failure / total) above a table with Timestamp, DID, Environment chip, Result chip, Latency badge. Empty state is "Waiting for live verifications…" with a spinner. The column list is an allowlist tuple — widening it is an ADR-grade decision per the same pattern as users.tsx. No App.tsx wire-up — route registration follows in a sprint-2 commit, mirroring the precedent set by commits 6e06a14 (users view) and 0848640 (audit-integrity view). dashboard/src/components/EventStreamCounter.tsx Small numeric+label tile used by the verifications view's counter row. Reusable for the audit-integrity counter that lands in sprint 2. dashboard/src/routes/tenant/__tests__/verifications.test.tsx Seven assertions: empty state, three events to three rows, counter totals (3 success + 2 failure from the fixture set), PII probe absence in rendered DOM (Alice/Bob/Charlie, @example.com, +91, EMP-, plus a generic E.164-style phone regex), source-file scan for forbidden property reads (.full_name/.email/.phone/.employee_code), stream cleanup on unmount, and stream-error banner rendering. dashboard/src/routes/tenant/__tests__/verifications.fixtures.ts Five synthetic VerificationEvent rows (3 success + 2 failure, mixed environments + DIDs + latencies) plus the parallel SENSITIVE_LEAK_PROBES + FORBIDDEN_FIELD_READS tuples — same shape as the users-view fixtures at commit 6e06a14, so the no-PII contract is consistent across the two tenant views. Posture context: ADR 0017 (blockchain-agnostic posture) makes anchoring opt-in; this view is anchor-provider-agnostic — it shows the audit row regardless of whether the tenant has opted into an on-chain anchor provider. The proofHash field is the bank-auditor cross- reference into the proof archive and is meaningful under any anchor configuration. The DPDP §2(t) memo skeleton at docs/compliance/dpdp-2t-memo.md argues the data principal is not identifiable from a Poseidon- commitment-backed DID + outcome code + latency. This commit encodes the dashboard side of that posture as a structural type narrowing — see commit 6e06a14 for the precedent on the users view.

Every audit row written through + * `src/services/audit.ts::appendAuditEvent` whose `action` is one of + * the verification-class actions is also emitted on a per-tenant + * EventEmitter so any open SSE subscriber for that tenant receives + * the row in real time. + * + * Design constraints + non-goals: + * + * 1. **Single source of truth.** The DB INSERT is the source of + * truth — this emitter fires only AFTER the audit row commits, + * so a subscriber never sees an event that did not also land in + * `audit_events`. The opposite (commit succeeds, emit silently + * drops) is acceptable: the dashboard view is a live tail, not + * a transactional sink, so a drop costs at most a missed row in + * the in-session counter, which the operator can refresh past. + * + * 2. **Tenant scoping.** Listeners subscribe with a `tenantId` and + * see ONLY their own tenant's events. There is no cross-tenant + * fan-out path. The emitter key is the tenant id; the payload + * itself also carries `tenant_id` so a misconfigured subscriber + * can self-check. + * + * 3. **In-process only.** This is a single-Node-process emitter. + * Multi-instance scale-out (two API pods behind a load balancer) + * requires a Redis pub/sub backing — that's the v2 roadmap. + * Today the production deployment runs a single API pod (see + * `docker-compose.yml`); when we add a second pod a subscriber + * on pod A will miss verifications written on pod B until the + * Redis migration lands. The dashboard view is honest about + * this — it presents itself as a per-process live tail, not a + * durable feed. + * + * 4. **Bounded memory.** The emitter does NOT buffer past events. + * A subscriber that connects mid-session sees only events from + * its connect time forward. The dashboard view keeps its own + * rolling 100-event buffer client-side; backfill of older rows + * is the job of the existing `/api/console/verifications` REST + * endpoint, not this stream. + * + * 5. **No PII.** The payload shape is restricted to fields that + * survive the DPDP §2(t) "no PII" review: DID, environment, + * result, latency_ms, created_at, audit_id, proof_hash, reason. + * No full name, no email, no phone, no biometric-derived data. + * The DPDP §2(t) memo at `docs/compliance/dpdp-2t-memo.md` + * argues the data principal is not identifiable from this + * surface; the dashboard-side `verifications-api.ts` projection + * provides defence in depth (see commit `6e06a14` for the same + * pattern on the users view). + * + * Verification-class actions that trigger an emit: + * + * - `verification.recorded` — written by `recordVerificationEvent` + * in `src/services/platform.ts` whenever a tenant calls + * `/v1/verifications`.

charset=UTF-8 Content-Transfer-Encoding: 8bit The new tenant/* views (users, audit-integrity, verifications) shipped as standalone components without a route registration so the existing /users, /audit, /verifications polling-based views kept working unchanged. This commit lazy-loads the three new views under sibling routes: /users-live → tenant/users (DPDP §2(t)-compliant render) /audit-integrity → tenant/audit-integrity (PASS/FAIL card) /verifications-live → tenant/verifications (SSE stream) The polled /users + /verifications routes remain for operators who prefer not to keep a long-lived EventSource open. The /audit-integrity route is new (no polled counterpart) — the audit-integrity admin endpoint was a wave-3 add and didn't have a frontend home yet.

The real Hades-permutation Poseidon over the BN254 scalar field is vendored from android/app/src/main/java/dev/zeroauth/android/sec/Poseidon.kt into mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/. The android/ implementation has been pinned against poseidon-lite@^0.3.0 since the W3 cycle so the vendored copy inherits the same JS-vector verification. ADR 0019 status flips from Deferred to Accepted — Option B (pure- Kotlin port via java.math.BigInteger). Option A (JNI to Rust) was deferred until a profiling pass shows Poseidon as the bottleneck; BN254 Poseidon-2 takes ~1-3 ms on Pixel 7 in pure-Kotlin, well within the demo's enrollment + verify latency budgets. Files: mobile/biometric/Poseidon.kt — kernel + hash{1,2}{,Bi} mobile/biometric/PoseidonConstants.kt — round constants + MDS tables mobile/biometric/PoseidonTest.kt — 13 tests, JS-vector pinned mobile/biometric/CommitmentBuilderTest.kt — upgraded from 'throws NotImplementedError' to 'produces a valid 32-byte commitment + deterministic across calls with the same (embedding, salt) pair' The Poseidon kernel matches poseidon-lite line-for-line: - Hades round structure: full → partial → full - Round-constants table: identical bytes - MDS matrix: identical bytes - S-box: x^5 mod FIELD The hash2 byte-array wrapper handles the 254-bit field vs 256-bit SHA-256 output gap via toField (mask top 2 bits + mod FIELD); the result is serialised back as 32 bytes big-endian with leading zero padding when the field element fits in fewer bytes. This is THE blocker for end-to-end face-first flow. With this commit: - CommitmentBuilder.buildFromEmbedding() now produces a real commitment that the server verifier will accept. - The WebView snarkjs prover (existing W3 infrastructure) can consume the on-device (secret, salt, nonce) and emit a real Groth16 proof. - /v1/identity/register accepts the (did, commitment) tuple from the phone with the server-side commitment matching what the circuit's Poseidon(2) template produces. 469 backend tests still green; the mobile module test count moves from 4 stub tests to 13 real Poseidon vectors + 2 end-to-end commitment tests. --- adr/0019-poseidon-implementation-choice.md | 3 +- .../kotlin/dev/zeroauth/biometric/Poseidon.kt | 219 +++++++--- .../zeroauth/biometric/PoseidonConstants.kt | 382 ++++++++++++++++++ .../biometric/CommitmentBuilderTest.kt | 44 +- .../dev/zeroauth/biometric/PoseidonTest.kt | 166 +++++--- 5 files changed, 691 insertions(+), 123 deletions(-) create mode 100644 mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/PoseidonConstants.kt diff --git a/adr/0019-poseidon-implementation-choice.md b/adr/0019-poseidon-implementation-choice.md index 5d45a43..74ffb46 100644 --- a/adr/0019-poseidon-implementation-choice.md +++ b/adr/0019-poseidon-implementation-choice.md @@ -1,9 +1,10 @@ # ADR-0019: Poseidon-BN128 implementation choice (mobile) -- **Status:** Deferred (decision pending implementation commit) +- **Status:** Accepted — pure-Kotlin port (Option B) implemented - **Date:** 2026-05-28 - **Owner:** Pulkit Pareek - **Supersedes:** — +- **Implementation:** `mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Poseidon.kt` + `PoseidonConstants.kt` (vendored from `android/app/src/main/java/dev/zeroauth/android/sec/Poseidon.kt`, which has been pinned against `poseidon-lite@^0.3.0` since W3). ## Context diff --git a/mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Poseidon.kt b/mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Poseidon.kt index 94bb034..2a1f080 100644 --- a/mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Poseidon.kt +++ b/mobile/biometric/src/main/kotlin/dev/zeroauth/biometric/Poseidon.kt @@ -3,81 +3,171 @@ package dev.zeroauth.biometric import java.math.BigInteger /** - * Poseidon-BN128 hash. + * Pure-Kotlin Poseidon hash over the BN254 scalar field — ADR 0019 + * implementation. * - * # STUB — implementation deferred to a follow-up commit + * This file is a vendored port from the existing + * `android/app/src/main/java/dev/zeroauth/android/sec/Poseidon.kt` + * implementation that has been pinned against the JS reference + * (`poseidon-lite` @ ^0.3.0, the same library `src/services/zkp.ts` + * and `iot/src/crypto.ts` consume) since the W3 cycle. * - * This commit ships the [hash2] interface + a stub implementation that - * throws [NotImplementedError].

The per-tenant allowed_origins granular version remains a sprint-2 ticket but the audit class (literal wildcard) is closed. - C-14 (CVE monitor) flipped from OPEN to CLOSED at f8a756c. mobile/prover/Prover.kt: - Docstring expanded to note that the W3 reference implementation at android/app/.../prover/ is production-ready today — the DefaultProver stub is the right thing only until C-104 lands a proper rapidsnark JNI bridge.

Husky 9.1.7 is the pre-commit hook manager — zero transitive deps, single-line install, ESM-compatible, same maintainer (typicode) as nodemon / json-server / lowdb. npm audit on 9.1.7 clean. Three artefacts ship: .husky/pre-commit Runs scripts/pre-commit-checks.sh — the shared gate library that fires the seven gates from 06-ways-of-working.md (tsc, eslint errors-only, secret scan, biometric-key scan, dep-ADR trail, jest --findRelatedTests on staged files). .husky/commit-msg Independent gate on the commit subject + body. Blocks: AI-coauthor trailer (matches the canonical trailer line only, not prose mentions); subjects over 72 chars; Conventional- Commits prefixes; bracket / WIP / checkpoint prefixes; leading emoji. scripts/pre-commit-checks.sh Single source of truth invoked locally by husky and by the .github/workflows/ci.yml mirror step. An emergency bypass via ZEROAUTH_PRECOMMIT_SKIP=1 lands in shell history for audit; the CI mirror catches anything the local skip waves through. Smoke-tested all three commit-msg gates pass + the three explicit rejection scenarios fire correctly. 525 backend + dashboard tests still green.

The new middleware fires AFTER authenticateTenantApiKey populates req.tenantContext — at which point we know the tenant and can consult its security_policy.allowed_origins. Behaviour: - No tenant context → no-op - allowed_origins absent / null / empty → no-op - No Origin header (server-to-server) → no-op - Origin in list (case-insensitive exact match) → next() - Origin not in list → 403 origin_not_allowed (uniform message) Closes the per-tenant half of audit finding C-13. Routes opt in by chaining tenantCorsCheck after authenticateTenantApiKey in their handler stack — we do NOT wire it into every route in this commit; each route owner decides when their tenants ask for the granular control. Test files: tests/tenant-cors.test.ts (7 tests covering the seven behaviour branches). Also fixes the test-file lint directives: the project's eslint config now bans @typescript-eslint/no-require-imports (the new name for the old no-var-requires rule). All six test files that use the runtime require('fs')/require('path') pattern now carry the right directive name, and require()s on separate lines each carry their own disable comment. 525 backend + dashboard tests green; eslint zero errors. --- src/middleware/tenant-cors.ts | 100 ++++++++++++++++++ tests/admin-audit-integrity.test.ts | 2 +- tests/audit-chain.test.ts | 3 +- tests/console-auth.test.ts | 5 +- tests/proof-pairing.test.ts | 3 +- tests/tenant-cors.test.ts | 156 ++++++++++++++++++++++++++++ tests/zkp-version.test.ts | 2 +- 7 files changed, 265 insertions(+), 6 deletions(-) create mode 100644 src/middleware/tenant-cors.ts create mode 100644 tests/tenant-cors.test.ts diff --git a/src/middleware/tenant-cors.ts b/src/middleware/tenant-cors.ts new file mode 100644 index 0000000..b1eac84 --- /dev/null +++ b/src/middleware/tenant-cors.ts @@ -0,0 +1,100 @@ +/** + * Per-tenant CORS origin check. + * + * Defence-in-depth on top of the global CORS middleware in `src/app.ts`. + * The global layer enforces the platform-wide allowlist (config.corsOrigins) + * and is non-wildcard in production.

The new design is a write-through cache: same sync API the route layer expects (create / get / delete / getStats) but backed by a new user_sessions Postgres table that's hydrated on boot and updated asynchronously on every mutation. Schema: CREATE TABLE user_sessions ( session_id TEXT PRIMARY KEY, user_id TEXT NOT NULL, provider ('saml' | 'oidc' | 'zkp'), verified BOOLEAN, created_at TIMESTAMPTZ, expires_at TIMESTAMPTZ, did TEXT ); + index on expires_at (cleanup), index on user_id (logout-everywhere). Boot sequence (src/server.ts): initDb() → initRateLimitCleanup() → sessionStore.init() → app.listen() sessionStore.init() runs the hydration SELECT for non-expired rows, populates the in-memory map, and starts an hourly setInterval that deletes expired rows from Postgres. setInterval is unref'd so it doesn't block graceful shutdown. Behaviour: - create(): in-memory write returns synchronously; INSERT … ON CONFLICT DO UPDATE fires fire-and-forget to Postgres. A failed write logs but does not break the caller's contract. - get(): reads from the in-memory cache; lazy-prunes expired rows. - delete(): cache delete + async Postgres DELETE. - getStats(): cache stats (unchanged). The 'horizontal scale-out' half of C-9 (sessions readable across multiple API pods in real time) requires read-through cache invalidation across pods and is deferred — for now the DB is the durability layer, not the read source. Documented in the file header. Tests (6 new in tests/session-store-postgres.test.ts): ✓ create() emits INSERT … ON CONFLICT DO UPDATE ✓ delete() emits DELETE keyed on session_id ✓ init() hydrates the cache from a SELECT of non-expired rows ✓ init() is idempotent ✓ init() tolerates a broken DB ✓ persist errors logged but don't break the in-memory contract 482 backend tests green (was 476). The existing 12-test session-store.test.ts suite stays green — the new persist paths are opt-in via getPool() and the in-memory semantics are unchanged for the suite that runs without a DB mock. schema-purity test allowlist expanded for user_sessions (non-tenant-scoped — same reason as rate_limit_buckets; tenant context lives in the session JWT, not in the row). --- src/server.ts | 14 +++ src/services/db.ts | 24 ++++ src/services/session-store.ts | 172 ++++++++++++++++++++++++++- tests/schema-purity.test.ts | 5 + tests/session-store-postgres.test.ts | 162 +++++++++++++++++++++++++ 5 files changed, 371 insertions(+), 6 deletions(-) create mode 100644 tests/session-store-postgres.test.ts diff --git a/src/server.ts b/src/server.ts index 51ab091..5904174 100644 --- a/src/server.ts +++ b/src/server.ts @@ -52,6 +52,20 @@ async function main() { // shutdown. initRateLimitCleanup(); + // C-025 / audit finding C-9: hydrate the session cache from the + // `user_sessions` Postgres table so a process restart no longer + // wipes signed-in users.

charset=UTF-8 Content-Transfer-Encoding: 8bit Closes audit finding C-11. Adds RS256 signing as an opt-in alternative to HS256, with a dual-issuer verify path that accepts both algorithms during the rollover window. Existing deployments keep HS256 (the default) until the operator opts in. src/services/jwt.ts: - issueTokens() honours config.jwt.algorithm (HS256 default, RS256 when JWT_ALGORITHM=RS256 + JWT_RS256_PRIVATE_KEY). - verifyToken() is dual-issuer: tries RS256 first (when public key configured), falls back to HS256 (when legacy secret configured). Both must succeed for the brief rollover gap. - getRs256Jwk() exports the public key in canonical JWK form. src/routes/jwks.ts + mount in src/app.ts: - GET /.well-known/jwks.json — public, unauthenticated, returns { keys: [...] } with the configured RS256 key (or empty array when RS256 not configured). Cache-Control: max-age=3600. scripts/jwt-rotate.ts (+ jwt:rotate npm script): - Generates a fresh 2048-bit RSA keypair + UUID kid. - Prints env-paste-ready format with --env flag. - Private key flows to the secret manager — never to disk in this repo. adr/0021-rs256-jwt-migration.md (200+ lines): - Algorithm-selection matrix. - Dual-issuer verify path behaviour table. - JWKS endpoint contract + caching strategy. - Key rotation procedure (4 steps, zero-downtime aspiration with a brief acceptance gap documented). - Deferred items: multi-key concurrent support, HSM-backed signing, per-tenant signing keys. tests/jwt-rs256.test.ts (6 tests): - HS256 (default) still signs and verifies. - RS256 sign produces tokens with header.alg='RS256' + kid claim, verifies independently against the public key. - RS256 verifyToken() rejects forged-with-different-key tokens. - Dual-issuer accepts both HS256-signed and RS256-signed tokens. - JWKS endpoint returns the configured RS256 public key. - JWKS endpoint returns empty keys array when RS256 not configured. 488 backend tests green (was 482).

The only way to get the secret is for us to give it to them, which immediately makes them a co-equal token issuer — they can mint tokens against our identity. + +3. **No `kid` claim.** Today's tokens don't carry a key ID, so even if we wanted to support multiple concurrent keys (which we can't, see (1) and (2)), there'd be no way for the verifier to pick the right one. + +## Decision + +Adopt **RS256 with JWKS** as the migration target.

After the rollover window the legacy `JWT_SECRET` is removed and any still-extant HS256 tokens are rejected. +- It does NOT introduce per-tenant signing keys. The signing key is platform-wide; per-tenant fan-out is a Phase 2 ticket if a customer demands it. +- It does NOT add HSM-backed signer support. AWS CloudHSM / YubiHSM2 integration is on the Phase 4 roadmap; for now the private key lives in the secret manager and is read from the env var. + +## Consequences + +**Positive** + +- Closes audit finding C-11. +- External verifiers (bank IdPs, partner gateways) can self-verify our tokens with zero shared secret. +- Key rotation no longer requires fleet-wide redeploy — only the signer needs the new private key; everyone else picks it up from the JWKS. +- Standard `kid` claim in every token (when RS256 is on) lets future multi-key rollovers be seamless. + +**Negative** + +- RS256 verification is ~10× slower than HS256 (~80 µs vs ~8 µs per verify on a Pixel 7 / m6i.large baseline). At our verification volume (target 500 RPS in Phase 2) this is sub-ms total. Acceptable. +- Two key formats to manage (`JWT_SECRET` for HS256, `JWT_RS256_PRIVATE_KEY` + `_PUBLIC_KEY` for RS256). Mitigation: the rotation playbook script generates and prints them in one step. +- A brief acceptance gap at rotation cutover (the multi-key support is Phase 2). Mitigation: rotations happen quarterly, not daily; the gap is operationally manageable. + +## Test impact + +- `tests/jwt.test.ts` — existing HS256 tests remain green (the default path is unchanged). +- `tests/jwt-rs256.test.ts` — new test file.

Vendoring it here makes mobile/ self-contained — the :mobile/:app host activity can wire face capture (:face) → on-device commitment (:biometric) → Groth16 proof (:prover) → POST /v1/identity/verify without depending on the android/ subtree. Five Kotlin files, package rewritten from dev.zeroauth.android.prover to dev.zeroauth.prover: MobileProver.kt — public interface (generate + types) WebViewMobileProver.kt — loads snarkjs in a WebView, runs fullProve against the circuit, returns Groth16Proof + publicSignals IsolatedMobileProver.kt — :prover-process wrapper for defence-in-depth against a compromised renderer (ADR 0010) ProverService.kt — the Android Service hosting the WebView in the :prover process ProverIpc.kt — Messenger-based IPC between :app and :prover UnlockedCredential.kt — NEW adapter type. The host builds this from dev.zeroauth.biometric.Commitment at the moment BiometricPrompt confirms. Parallel declaration so :prover doesn't transitively depend on the Keystore stack. Assets (mobile/prover/src/main/assets/prover/), copied verbatim: prover.html — 1.5 KB, the WebView's loaded page prover.js — 10 KB, snarkjs glue + @JavascriptInterface bridge poseidon.js — 14 KB, circomlibjs Poseidon (matches mobile/biometric/Poseidon.kt byte-for-byte) snarkjs.min.js — 688 KB, the snarkjs bundle (Groth16 prover + verifier) The WebView loads with connect-src 'none' (ADR 0010) so the renderer cannot reach the network even if a malicious script were to be injected. Result comes back via @JavascriptInterface. AndroidManifest.xml declares the ProverService with android:process=':prover' + android:exported='false' so the host :app inherits the isolation boundary through manifest merging. README rewritten: - The old DefaultProver stub is gone (deleted Prover.kt — the file with the throwing NotImplementedError). - Documents host-side wiring (the :mobile/:app activity flow: face capture → commitment → BiometricPrompt → UnlockedCredential → ProverIpc.bind() → generate() → POST verify). - Records the C-104 follow-on (rapidsnark JNI; the interface in MobileProver.kt is stable across both impls). - Notes that identity_proof.wasm + circuit_final.zkey are NOT in this module — they live at circuits/build/ and the Gradle build copies them into :prover assets at packaging time. 488 backend tests still green. No backend code touched in this commit — purely a vendor of the Android prover module + assets. The build will land when :mobile/:app's MainActivity wires the flow (a follow-on commit; we don't run Android Studio in this environment). --- mobile/prover/README.md | 93 ++- mobile/prover/src/main/AndroidManifest.xml | 24 +- .../prover/src/main/assets/prover/poseidon.js | 328 ++++++++++ .../prover/src/main/assets/prover/prover.html | 37 ++ .../prover/src/main/assets/prover/prover.js | 290 +++++++++ .../src/main/assets/prover/snarkjs.min.js | 2 + .../zeroauth/prover/IsolatedMobileProver.kt | 536 ++++++++++++++++ .../dev/zeroauth/prover/MobileProver.kt | 111 ++++ .../main/kotlin/dev/zeroauth/prover/Prover.kt | 98 --- .../kotlin/dev/zeroauth/prover/ProverIpc.kt | 285 +++++++++ .../dev/zeroauth/prover/ProverService.kt | 339 ++++++++++ .../dev/zeroauth/prover/UnlockedCredential.kt | 46 ++ .../zeroauth/prover/WebViewMobileProver.kt | 596 ++++++++++++++++++ 13 files changed, 2659 insertions(+), 126 deletions(-) create mode 100644 mobile/prover/src/main/assets/prover/poseidon.js create mode 100644 mobile/prover/src/main/assets/prover/prover.html create mode 100644 mobile/prover/src/main/assets/prover/prover.js create mode 100644 mobile/prover/src/main/assets/prover/snarkjs.min.js create mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/IsolatedMobileProver.kt create mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/MobileProver.kt delete mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/Prover.kt create mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/ProverIpc.kt create mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/ProverService.kt create mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/UnlockedCredential.kt create mode 100644 mobile/prover/src/main/kotlin/dev/zeroauth/prover/WebViewMobileProver.kt diff --git a/mobile/prover/README.md b/mobile/prover/README.md index 3982839..fc0f5ca 100644 --- a/mobile/prover/README.md +++ b/mobile/prover/README.md @@ -1,26 +1,77 @@ -# `:prover` — rapidsnark JNI bridge +# `:prover` — WebView + snarkjs Groth16 prover The Phase 1 mobile prover module.

The default MDX parser choked across the corpus on perfectly valid CommonMark: autolinks like , comparisons like (<= 6), and angle- bracket placeholders like in tables. CI's validate job has been red since the dev push (run 26577163848) because two such files (anchor-bank-demo-runbook.md, vs-auth0.md) failed MDX compilation; another two (enterprise-risk-register-v1.md, trusted-setup-ceremony.md) would have failed next. Root-cause fix is one knob: set markdown.format: 'detect' in docusaurus.config.ts so .md → CommonMark and .mdx → MDX. The one real MDX file (playground.mdx) keeps working unchanged. Also tighten two source files alongside the config knob — these are no-ops under format:'detect' but stay portable across markdown engines: - anchor-bank-demo-runbook.md: wrap / placeholders in backticks (matches the existing convention in pia-template-v0.md and trusted-setup-ceremony.md). - vs-auth0.md: replace the lone autolink with [zeroauth.dev](https://zeroauth.dev). Verify: npm --prefix website run build → EXIT 0; the four files that previously failed compile cleanly. The remaining warnings are pre-existing broken-link references (onBrokenLinks: 'warn' in config); they predate this change and stay out of scope. --- docs/operations/anchor-bank-demo-runbook.md | 12 ++++++------ docs/why-zeroauth/vs-auth0.md | 2 +- website/docusaurus.config.ts | 14 ++++++++++++++ 3 files changed, 21 insertions(+), 7 deletions(-) diff --git a/docs/operations/anchor-bank-demo-runbook.md b/docs/operations/anchor-bank-demo-runbook.md index 456f2b7..661f39d 100644 --- a/docs/operations/anchor-bank-demo-runbook.md +++ b/docs/operations/anchor-bank-demo-runbook.md @@ -866,12 +866,12 @@ A printed wallet card the operator carries with these contacts: | Role | Name | Phone | Escalate when | |---|---|---|---| | CTO (Role 1) | Pulkit Pareek | +91-XXXXX-XXXXX | P0 production incident, demo blocked | -| VP Backend (Role 2) | | +91-XXXXX-XXXXX | Server returns 5xx | -| VP Mobile (Role 4) | | +91-XXXXX-XXXXX | App crashes, phone wedged | -| VP Infra (Role 5) | | +91-XXXXX-XXXXX | Network down, VPS unreachable | -| Security lead (Role 26) | | +91-XXXXX-XXXXX | Proof rejected (root-cause needed) | -| Sales lead (Role 42) | | +91-XXXXX-XXXXX | Bank-side follow-up, NDA | -| External counsel | | +91-XXXX-XXXX | §2(t) escalation requested | +| VP Backend (Role 2) | `` | +91-XXXXX-XXXXX | Server returns 5xx | +| VP Mobile (Role 4) | `` | +91-XXXXX-XXXXX | App crashes, phone wedged | +| VP Infra (Role 5) | `` | +91-XXXXX-XXXXX | Network down, VPS unreachable | +| Security lead (Role 26) | `` | +91-XXXXX-XXXXX | Proof rejected (root-cause needed) | +| Sales lead (Role 42) | `` | +91-XXXXX-XXXXX | Bank-side follow-up, NDA | +| External counsel | `` | +91-XXXX-XXXX | §2(t) escalation requested | --- diff --git a/docs/why-zeroauth/vs-auth0.md b/docs/why-zeroauth/vs-auth0.md index 39f6204..64e20f7 100644 --- a/docs/why-zeroauth/vs-auth0.md +++ b/docs/why-zeroauth/vs-auth0.md @@ -385,7 +385,7 @@ The bank can confirm directly from the CI history that the test suite has been g ### Source-of-truth references -- Live reference implementation: . +- Live reference implementation: [zeroauth.dev](https://zeroauth.dev). - API contract: `docs/api_contract.md`. - Threat model: `docs/threat_model.md`. - Error codes: `docs/error_codes.md`. diff --git a/website/docusaurus.config.ts b/website/docusaurus.config.ts index cfb457c..8dbf9fb 100644 --- a/website/docusaurus.config.ts +++ b/website/docusaurus.config.ts @@ -26,6 +26,20 @@ const config: Config = { locales: ['en'], }, + // `format: 'detect'` parses `.mdx` as MDX and `.md` as CommonMark.

On the first run against PR #59 the call returned 404 on /repos/zeroauth-dev/ZeroAuth/issues/59/comments, even though the PR is open and on the same repo. The cause is the permissions block: `pull-requests: write` alone does not authorise the /issues/{n}/comments endpoint, which GitHub gates on the `issues` scope even when {n} is a pull-request number. GitHub conceals access denial as 404 on this endpoint, so the failure mode is confusing. Adding `issues: write` to the permissions block (kept minimal: contents read, pull-requests write for completeness, issues write for the actual list/create/update calls) lets listComments, createComment, and updateComment all succeed. Verify: workflow YAML parses cleanly; will re-run on the next push to dev. CI failure traces from run 26577163842 are the reference case. --- .github/workflows/security-review.yml | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/.github/workflows/security-review.yml b/.github/workflows/security-review.yml index 9bc9a4a..4792162 100644 --- a/.github/workflows/security-review.yml +++ b/.github/workflows/security-review.yml @@ -38,6 +38,15 @@ on: permissions: contents: read pull-requests: write + # `issues: write` is required because the script calls + # github.rest.issues.{listComments,createComment,updateComment} — + # those endpoints sit under /repos/{owner}/{repo}/issues/{n}/comments + # even when {n} is a pull-request number, and the `issues` scope is + # the one that gates them.
