The document, `keys.json` schema, +and OCR/LLM extraction pipeline itself are described only insofar as they shape the +contract; the extraction engine ships as a cloud executor plugin (see +[§11, 501 behavior](#11-when-the-engine-is-unavailable-501-behavior) below). + +Design background: `docs/superpowers/specs/2026-08-28-agent-kv-api-design.md` (referred +to as "the spec" throughout this document; section numbers below are spec section +numbers). This document records what shipped, including a handful of places where the +implementation is more specific than — or diverges from — the spec's sketch. Those are +called out explicitly rather than silently reconciled. + +## 1. Authentication + +There are two independent auth schemes on two different URL prefixes: + +| Surface | Prefix | Auth | +|---|---|---| +| Public execution API (submit/status/result/cancel/validate) | `/agent-kv/…` (top-level, not under the tenant subfolder) | `Authorization: Bearer ` — a dedicated per-organization key, validated by the view itself | +| Key management (create/list/rotate/revoke) | `{PATH_PREFIX}/unstract/…/agent-kv/keys/…` (tenant-scoped, alongside Platform API key management) | Session auth, `IsOrganizationAdmin` only | + +The execution prefix (`AGENT_KV_PATH_PREFIX`, default `agent-kv`) sits **outside** the +tenant-subfolder/organization-middleware chain — it is added to `WHITELISTED_PATHS` in +`backend/backend/settings/base.py` — because a caller authenticates with an API key, not +a session/org header. Every view under it therefore owns its own auth via the +`AgentKVKeyValidator.validate_api_key` decorator (`backend/agent_kv/key_validator.py`), +which: + +1. Requires `Authorization: Bearer ` where `` is a UUID. +2. Looks up an active (`is_active=True`) `AgentKVKey` by that UUID. +3. Injects the resolved key object as `agent_kv_key` into the view kwargs, which every + subsequent lookup filters by (`organization_id=agent_kv_key.organization_id`) — this + is what makes a job in another org indistinguishable from an unknown job id (both + 404, see [Status](#4-status--get-agent-kvjob_id)). + +**Drift from the spec:** spec §6.1 describes this as "every endpoint 401s without a +valid key." The implementation returns **403** (`api_v2.exceptions.Forbidden`, reused +as-is rather than adding a new exception class) for both a missing/malformed +`Authorization` header and an unknown/inactive key. This is exercised directly by +`backend/agent_kv/tests/test_auth.py` and `test_job_views.py::test_all_job_views_401_without_key` +(the test name predates the code's actual status; both assert `403`). Document the code: +**403, not 401**, for any auth failure on the public prefix. + +Key management (`backend/agent_kv/views.py`, `AgentKVKeyViewSet`) is a standard DRF +`ModelViewSet` scoped by the global `OrganizationFilterBackend` and gated by +`IsOrganizationAdmin` (`backend/agent_kv/permissions.py`). Fields returned: +`id, name, description, key, is_active, created_at`; write-side fields are +`name, description, is_active` only (`key` and `id` are server-generated). Routes +(`backend/agent_kv/urls.py`, mounted at `agent-kv/` under +`backend/backend/urls_v2.py`): + +``` +GET/POST .../agent-kv/keys/ +GET/PATCH/DELETE .../agent-kv/keys// +POST .../agent-kv/keys//rotate/ # replaces `key` with a new UUID +``` + +Key storage follows the same conventions as Platform API key management (D5) — +plaintext-at-rest UUID keys, not hashed-at-rest; that hardening is explicitly deferred, +not a v1 gap unique to this feature. + +## 2. The extraction schema (`keys` field) + +The `keys` submit field — spec-called "keys.json" — is a JSON object describing what to +extract. It compiles through `unstract.agent_kv_schema.compile_schema` +(`unstract/agent-kv-schema/src/unstract/agent_kv_schema/`), the **single schema compiler +in the system**: the OSS API validates with it at submit time and at `/validate`, and +the cloud engine imports the same package to execute — the schema language cannot drift +between validation and execution by construction (spec §5.1). + +### Node types + +A schema node is one of three shapes, decided structurally: + +- **Interior node** — every value is itself an object → its keys are child nodes, and + nesting continues (dotted path, e.g. `vendor.address.city`). +- **Leaf node** — no value is an object → defined by scalar attributes: + + | Attribute | Required | Meaning | + |---|---|---| + | `description` | **yes** | Prompted to the extractor; also fed to the breadcrumb-prefixed `effective_description`. | + | `format` | no (default `string`) | `string` \| `number` \| `currency` \| `date` \| `enum:v1,v2,…` \| `regex:` \| any other free-text hint. `number`/`currency` parse via a strip-then-`float()` check; `date` accepts a fixed set of common formats; `enum` matches case-insensitively; `regex` is `re.fullmatch`. | + | `required` | no (default `false`) | Completeness is checked separately from format. | + | `aliases` | no (default `[]`) | Alternate names/labels to help the extractor recognize the field. | + | `multivalued` | no (default `false`) | Value is a comma-separated string; each element is format-checked independently. | + + A node mixing object values and scalar attributes is a **compile-time error** + ("mixes object children and scalar attributes"), as is a leaf with unknown attribute + keys or a missing `description`. + +- **Array node** — has an `_array` key → a flat (non-nested) row schema: + + ```json + "line_items": { + "description": "One row per invoice line", + "_key": "sku", + "_array": { + "sku": {"description": "SKU"}, + "total": {"description": "Line total", "format": "currency"} + } + } + ``` + + `_array`'s value is itself a flat object of leaf columns (row-local paths, not + dotted). `description` is optional context; `_key` (optional) names a column used for + row identity in downstream scoring, otherwise rows are matched positionally. A + nested array inside an array's row schema is rejected at compile time ("not supported + in P8a") — arrays are single-level only in v1. + + `_dedup` (optional, default `true`) controls whether rows identical in **every** + extracted column are collapsed to one. Leave it on for documents where + layout-preserving OCR repeats a row once per replicate column — that is what it + exists for. Set it to `false` when your documents can genuinely contain two + identical rows: + + ```json + "line_items": { + "_dedup": false, + "_array": { + "description": {"description": "Line description"}, + "total": {"description": "Line total", "format": "currency"} + } + } + ``` + + With `_dedup: true` an invoice listing the same item twice comes back with one + row, so the row count — and any `_constraints` aggregate over those rows — is + wrong. The default is `true` only because flipping it would break the OCR corpus + the extractor was built against; it is not the safer value for every document. + Must be a JSON boolean: `"false"` as a string is rejected rather than silently + read as true. + +### Constraints (`_constraints`) + +An optional top-level `_constraints` key: a list of string expressions checked against +the extracted record post-hoc.

It is **not** re-checked at connect time — the subsequent + `requests.post` call performs its own, independent DNS resolution, and nothing + pins that second resolution to the address(es) just validated. +- **Residual risk, accepted for v1: DNS-rebinding TOCTOU.** An attacker whose DNS + answer changes between the pre-check's resolution and `requests`' own resolution + a moment later (serving a public IP to the first, a private/internal IP to the + second) slips through this gap. The module's own docstring names this as a known, + accepted risk. **Fast-follow, not shipped:** IP-pinning the validated address into + the actual connection, so the two resolutions can never disagree. +- **Scheme: https-only**, in this feature's actual usage. `send_webhook` exposes a + generic `allow_http` escape hatch (for explicitly configured dev environments + elsewhere), but the Agent-KV caller (`_maybe_webhook`) never passes it — every + Agent-KV webhook is https-only in practice. +- **No redirects** (`allow_redirects=False`). +- **Fixed, minimal payload** (`{job_id, status}` only — see above) and the + **response body is never read** — only the status code is inspected. +- **Short timeout** (10 seconds). +- **No retries.** One POST attempt only; any failure (host refused by the + pre-check, timeout, connection error, non-2xx status) is logged and swallowed — + there is no retry loop anywhere in this delivery path. + +Test/dev stacks only: `AGENT_KV_WEBHOOK_INSECURE_ALLOW_HTTP_PRIVATE=1` on the +ide-callback worker waives both guards (http scheme and non-public host) so the +e2e lane can deliver to a receiver on the compose host. Never set it in +production. + +## 10. Retention and TTL + +- **Input deletion is completion-triggered, not TTL-based** (spec D10: "uploaded + document deleted on job completion"). `FinalizeView.post` + (`backend/agent_kv/internal_views.py`) deletes the staged input file and blanks + `input_ref` the instant a finalize call actually wins the terminal-state guard (the + job just became `COMPLETED` or `FAILED`), via `storage.delete_input` — which only + ever touches `input_ref`, never `result_ref`/the result file. A duplicate/late + finalize call (guard already lost, since the job is already terminal) never deletes + anything: either the winning call already did, or the job reached terminal some + other way (see next bullet). +- **Cancelled jobs' inputs intentionally ride TTL instead.** `JobCancelView` marks a + job `CANCELLED` directly via `AgentKVJob.mark_terminal`, not through `FinalizeView` + — so cancellation never triggers the completion-time delete above. A late finalize + call against an already-`CANCELLED` job also no-ops (it loses the terminal guard, + same as any duplicate). A cancelled job's staged input is therefore cleaned up the + ordinary way: by the TTL sweep once `expires_at` passes, or by an explicit + `DELETE /agent-kv/{job_id}`. +- **Result retention**: `AGENT_KV_RESULT_TTL_DAYS` (default **7** days, D10's + engineering default) — results are re-readable until then, then swept by the + internal `ttl-cleanup` endpoint ([§12](#12-deploy-checklist)), which blanks + `result_ref` (and `input_ref` too, covering the cancelled-job case above, or + defensively for any input that somehow outlives completion). The job row itself is + never deleted (audit trail persists past TTL, only the object-store payloads are + dropped). +- **`expires_at` is stamped at submit time**, not at completion — + `SubmitView.post` sets `expires_at = timezone.now() + timedelta(days=AGENT_KV_RESULT_TTL_DAYS)` + before dispatch even runs. **This is a real divergence from spec D10's framing** + ("results retained 7 days" implicitly from completion): for a job that runs close to + its `timeout` ceiling, the effective post-completion retention window is slightly + under the full 7 days. Documented here as shipped behavior, not silently + reconciled — flagged for anyone tightening D10 later. + +## 11. When the engine is unavailable (501 behavior) + +The Django backend cannot see the executor plugin registry (that lives in the workers +process). Dispatching to a queue no worker consumes would hang, not error — so gating +happens **before enqueue, in the backend**, via a capability probe: + +```python +if not get_plugin("agent_kv"): + raise EngineUnavailable() # 501, "agent-kv engine not available on this deployment" +``` + +`get_plugin(...)` (`backend/plugins/__init__.py`) returns an empty dict — falsy — when +no `plugins/agent_kv/` package is installed, which is the OSS-only case by design (the +plugin is a cloud deliverable, spec §5.1/§11: "OSS scaffold merges dark"). Every +`POST /agent-kv/` on an OSS-only deployment therefore returns: + +```json +{"detail": "agent-kv engine not available on this deployment"} +``` + +with HTTP `501`. `/validate`, key management, status/result/cancel/delete on +*already-existing* jobs are unaffected by this gate — only `SubmitView` probes it, +since only submit needs the engine. + +### 11a. The cancel-at-pickup contract (internal API — frozen; build the cloud engine against this) + +Spec §7.4 states that "a job not yet picked up is dropped at pickup," but leaves the +actual mechanism unspecified. This is it, and it is load-bearing enough that it is +recorded here explicitly rather than left to be inferred from the internal-API code: + +`POST /internal/v1/agent-kv/jobs/{job_id}/stage/` — the stage-report endpoint +(`StageReportView`, `backend/agent_kv/internal_views.py`) — no-ops with +`{"ok": true, "noop": true}` whenever the target job is already terminal (its +candidate query excludes `AgentKVJob.TERMINAL`, so a terminal job's row is simply +never found). **That response body *is* the drop signal.** The FIRST stage report an +executor makes for a job it has just picked up doubles as a liveness check against a +job that was cancelled (or otherwise reached a terminal state) in the window between +dispatch and pickup — since there is no task-revocation machinery anywhere in the +platform (spec §7.4) to stop a picked-up job any other way. + +On `noop: true`, the executor **must**: + +1. Stop doing any further work on that job immediately. +2. **Still call `FinalizeView`** (`POST .../jobs/{job_id}/finalize/`) with whatever + outcome it has — success or failure, it does not matter which, since the write is + going to no-op either way. + +Step 2 is not optional. `FinalizeView`'s terminal-state guard (spec §5.4) correctly +no-ops the status write for an already-terminal job — but its concurrency-slot +release (`AgentKVConcurrencyLimiter.release`) lives in a `finally`, unconditional on +whether the guard actually won ([§10](#10-retention-and-ttl) covers the input-deletion +side of this same guard). An executor that treats `noop: true` as "nothing left to do +here" and skips the finalize call entirely leaks that job's concurrency slot for the +rest of the limiter's TTL (6 hours) instead of releasing it immediately. This is the +entire mechanism behind a pre-pickup cancel actually being observed and cleaned up +promptly — there is no other signal. + +## 12. Deploy checklist + +Everything below is required (or worth checking) to run this feature for real, +beyond `docker compose up`: + +1. **Cloud plugin**: install/enable the `agent_kv` backend capability plugin + (probed via `plugins.get_plugin("agent_kv")`) — without it, submit always 501s + ([§11](#11-when-the-engine-is-unavailable-501-behavior)). This repo ships gated + dark by design; nothing to do for an OSS-only deployment except accept the 501. + The marker the probe keys off is the mere presence of + `backend/plugins/agent_kv/__init__.py` — a cloud image ships it (via the + plugin-copy step), an OSS-only build does not. +2. **Executor worker fleet queue**: the executor dispatch derives its Celery queue name + from the executor name as `celery_executor_{executor_name}` — for Agent-KV that's + **`celery_executor_agentic_kv`** (`unstract/sdk1/src/unstract/sdk1/execution/dispatcher.py`). + `workers/run-worker.sh`'s executor role default queue list + (`celery_executor_legacy,celery_executor_agentic,celery_executor_agentic_table`) + does **not** include it — a self-hosted/OSS-only deployment running the cloud + `agentic_kv` executor plugin must add `celery_executor_agentic_kv` to that worker's + consumed queues (`CELERY_QUEUES_EXECUTOR` on the Docker path, or the equivalent + `run-worker.sh` queue map entry) or dispatched jobs will never be picked up. + **The cloud Helm chart already wires this**: both `workerExecutorV2.args` + (`--queues=...,celery_executor_agentic_kv`) and + `workerPgExecutor.env.WORKER_PG_QUEUE_CONSUMER_QUEUE` include it, and both fleets + carry `additionalConfigs: [..., agentKv]` (`charts/unstract-platform/values.yaml`, + cloud repo) so the executor pods get the `AGENT_KV_*` LLM/LLMWhisperer env alongside + the queue wiring. +3. **Callback queue**: the `ide_callback` worker must consume `agent_kv_callback` + alongside its own `ide_callback` queue, or jobs dispatch but never finalize. This is + already the hardcoded default in both `workers/run-worker-docker.sh` and + `workers/run-worker.sh` (`WORKER_QUEUES["ide_callback"] = "ide_callback,agent_kv_callback"`) + — nothing to configure for a standard deployment; see the note already in + `docker/sample.env` under "IDE Callback Worker." The cloud Helm chart matches: + `workerIdeCallbackV2.args` (`--queues=ide_callback,agent_kv_callback`) and + `workerPgIdeCallback.env.WORKER_PG_QUEUE_CONSUMER_QUEUE` + (`"ide_callback,agent_kv_callback"`) both already include it + (`charts/unstract-platform/values.yaml`, cloud repo). +4. **Internal periodic maintenance — proxy tasks now exist; nothing schedules them + yet.** Two internal endpoints do the real work + (`backend/agent_kv/internal_urls.py`, `internal_views.py::SweepView`/ + `TTLCleanupView`), and thin scheduler-side proxy tasks now call them — + `workers/scheduler/agent_kv_tasks.py::agent_kv_sweep`/`agent_kv_ttl_cleanup`, + registered under the wire names `agent_kv.sweep`/`agent_kv.ttl_cleanup` — mirroring + the dashboard-metrics periodics (`workers/scheduler/dashboard_metrics_tasks.py`) + this feature was designed to follow (spec §5.4), except the call goes through the + shared `InternalAPIClient` facade (`agent_kv_sweep`/`agent_kv_ttl_cleanup` methods on + `workers/shared/api/internal_client.py`) rather than a second bespoke HTTP client. + **Nothing calls these tasks on a schedule yet** — an operator must register both as + periodic tasks via the same PG-scheduler mechanism the dashboard-metrics periodics + use: a `PgPeriodicTask` row per task (`name`, `task_name` = the wire name above, + `queue`, `cron_string`, `enabled=True`, `pg_owned=True` once ready to go live — see + `backend/dashboard_metrics/migrations/0004_pg_periodic_tasks.py` for the exact row + shape this mirrors) before relying on TTL cleanup or stuck-job recovery: + - `agent_kv.sweep` → `POST /internal/v1/agent-kv/sweep/` — terminalizes `PENDING` + jobs never dispatched within `AGENT_KV_SWEEP_GRACE_SECONDS` (default 1 hour) + **and** `DISPATCHED`/`RUNNING` jobs stuck past `AGENT_KV_STUCK_JOB_GRACE_SECONDS` + (default 6 hours) — two independent phases per call, response + `{"swept": N, "timed_out": M}`. Suggested cadence: every few minutes. + - `agent_kv.ttl_cleanup` → `POST /internal/v1/agent-kv/ttl-cleanup/` — deletes + staged input/result files past `expires_at`. Suggested cadence: hourly or daily + (retention is measured in days). + Both endpoints are idempotent, batch-capped at 500 rows per phase per call, and + safe to call more often than needed. + + **Cloud mechanism — Kubernetes CronJobs, not the PG-scheduler.** The sweep and + TTL-cleanup logic itself lives in `backend/agent_kv/maintenance.py::run_sweep`/ + `run_ttl_cleanup` — `SweepView`/`TTLCleanupView` above are now thin wrappers + around it. Two Django management commands wrap the same functions — + `python manage.py agent_kv_sweep` and `python manage.py agent_kv_ttl_cleanup` + (`backend/agent_kv/management/commands/`) — each printing the JSON counts + (`{"swept": N, "timed_out": M}` / `{"cleaned": N}`) and exiting 0. In the cloud + deployment, a Kubernetes CronJob runs each command on the cadences above instead + of registering a `PgPeriodicTask` row. The scheduler proxy tasks + (`agent_kv.sweep`/`agent_kv.ttl_cleanup`) and their PG-scheduler registration + remain the mechanism for OSS/self-hosted deployments, which have no CronJob + equivalent to drive from. + + **Chart keys (cloud repo)**: `backend.agentKvCronJobs` in + `charts/unstract-platform/values.yaml` — `enabled: false` there (on-prem never runs + it), flipped to `enabled: true` in `charts/cloud-deployment-values/cloud.values.yaml`. + Its `jobs` list is the two commands above with concrete schedules: + `{name: sweep, command: agent_kv_sweep, schedule: "*/15 * * * *"}` and + `{name: ttl-cleanup, command: agent_kv_ttl_cleanup, schedule: "17 * * * *"}` — offset + from sweep's :00/:15/:30/:45 ticks so the two CronJobs never contend on the same + rows. Neither job needs the `agentKv` shared-config group (LLM/LLMWhisperer + creds — only the executor touches those): sweep only needs `database`/`redis`, + ttl-cleanup additionally needs `storage` for `AGENT_KV_FILE_STORAGE_CREDENTIALS` + (see item 6 below) — both already on the `backend` deployment's config list. +5. **Env vars**: every `AGENT_KV_*` setting plus `AGENT_KV_FILE_STORAGE_CREDENTIALS` — + see [§13](#13-environment-reference) and `docker/sample.env`. The executor-side vars + (read by the cloud `agentic_kv` plugin, not by the backend settings in §13) are a + separate chart group: `global.sharedConfigs.agentKv` + (`charts/unstract-platform/values.yaml`, cloud repo) — + `AGENT_KV_LLM_PROVIDER`, `AGENT_KV_LITE_MODEL`, `AGENT_KV_ADVANCED_MODEL`, + `AGENT_KV_LLM_API_KEY`, `AGENT_KV_LLMWHISPERER_API_KEY`, + `AGENT_KV_LLMWHISPERER_BASE_URL`, `AGENT_KV_MAX_TOKENS`, `AGENT_KV_PARALLEL_PAGES`, + `AGENT_KV_ENGINE_VERSION`. Of those, two are ESO (External Secrets Operator) + secrets rather than plain values — `AGENT_KV_LLM_API_KEY` and + `AGENT_KV_LLMWHISPERER_API_KEY`, mapped in `global.externalSecrets.groups.agentKv` + to the GCP Secret Manager suffixes `agent-kv-llm-api-key` / + `agent-kv-llmwhisperer-api-key`. `AGENT_KV_LLM_PROVIDER` is a v1 hard allowlist of + two values — `anthropic` and `openai` (`SUPPORTED_PROVIDERS` in the executor's LLM + adapter) — anything else raises `ConfigError` at dispatch, before any LLM call. + + **Rollout order is strict, and getting it wrong takes down the whole executor + fleet.** Both executor fleets mount this group with `envFrom: secretRef: + -agent-kv`, so no executor pod of any kind — not just Agent-KV ones — + can start until that Secret exists: enabling the group ahead of its contents + leaves `workerExecutorV2` and `workerPgExecutor` in `CreateContainerConfigError`. + Per environment, in this order: (1) create the two GCP Secret Manager secrets + `-agent-kv-llm-api-key` and + `-agent-kv-llmwhisperer-api-key`; (2) set the three + non-secret keys — `AGENT_KV_LLM_PROVIDER`, `AGENT_KV_LITE_MODEL`, + `AGENT_KV_ADVANCED_MODEL` — in that environment's own values file (under ESO they + are emitted as inline literals in the ExternalSecret's `target.template`, and a nil + value is silently **dropped**, so leaving them unset ships a Secret without them and + every Agent-KV job then fails at dispatch with `ConfigError: Missing required + Agent-KV env vars`); (3) only then roll the fleets out. `cloud.values.yaml` enables + the group fleet-wide, so step 2 is a per-environment prerequisite, not an optional + extra. In inline (non-ESO) mode the same three keys are enforced at render time by a + `fail` guard in `charts/unstract-platform/templates/shared/agent-kv-secret.yaml`, so + a mistake there is a loud deploy-time failure instead of a per-job runtime one. +6. **Object storage**: `AGENT_KV_FILE_STORAGE_CREDENTIALS` must point at a real bucket + in production (defaults to the same shared MinIO instance as workflow execution). + Paths are prefix- and org-rooted + (`{AGENT_KV_STORAGE_DIR_PREFIX}/{org_id}/{job_id}/input{ext}`, `.../result.json`) — + no document bytes ever ride the message broker. Chart key: + `global.sharedConfigs.storage.AGENT_KV_FILE_STORAGE_CREDENTIALS` + (`charts/unstract-platform/values.yaml`, cloud repo) — derived from + `fileStorageCredentials`/`MINIO_CREDS` unless set explicitly, the same fan-out + pattern as its three siblings (`WORKFLOW_EXECUTION_`, `API_`, + `HITL_FILES_FILE_STORAGE_CREDENTIALS`). +7. **`AGENT_KV_STORAGE_DIR_PREFIX` — must be set on the backend *and* the executor + fleet, to the same value** (default `unstract/agent_kv`). The **first segment is the + bucket** — s3fs/gcsfs read it that way — so it must be a bucket that already exists + (the MinIO dev bootstrap creates `unstract`); a bucket-less prefix makes every submit + fail `NoSuchBucket` and return a 500 with nothing billed. The executor reads the + backend-staged `input_ref` and keys its OCR cache under the same root + (`{prefix}/{org_id}/cache/…`), so a mismatch silently splits the cache and breaks + result read-back. Unlike the executor-only group in item 5, this one has to reach + **both** sides, so in the chart (cloud repo) it must be fanned out to the backend + *and* to `workerExecutorV2`/`workerPgExecutor` from a single source of truth — never + set independently per fleet, where the two can drift apart unnoticed. +8. **Feature flags — `calculations` and `structured_output`**: the cloud engine + cannot execute these yet, so submit rejects them with a 400 until the flags are + flipped. Both `AGENT_KV_CALCULATIONS_ENABLED` and + `AGENT_KV_STRUCTURED_OUTPUT_ENABLED` default `false`; set either to `true` only + once the executor side has shipped support for it. +9. **Executor time limit — the real baseline is 3,600s, not 7,200s.** The executor + fleet (`workerExecutorV2`/`workerPgExecutor`) is not a `FILE_PROCESSING` worker — + `WorkerConfig._get_worker_specific_timeout_defaults()` + (`workers/shared/models/worker_models.py`) falls through to the "conservative + defaults for other workers" branch for `WorkerType.EXECUTOR`: **1 hour / 3,600s** + hard limit, 3,300s soft. The chart's bare `TASK_TIME_LIMIT: "3600"` ConfigMap key + is inert — `get_celery_setting`'s 4-tier resolution (cmdline → + `{WORKER_TYPE}_{SETTING}` → `CELERY_{SETTING}` → default) means only + **`EXECUTOR_TASK_TIME_LIMIT`** (worker-specific) or `CELERY_TASK_TIME_LIMIT` + (global) actually override it; see the comment on `workerExecutorV2`'s + `terminationGracePeriodSeconds` in `charts/unstract-platform/values.yaml`, which + already documents this ("Its ceiling is task_time_limit=3600s... note the chart's + bare TASK_TIME_LIMIT is NOT read; only EXECUTOR_TASK_TIME_LIMIT / CELERY_*"). + At the 100-page cap (`AGENT_KV_MAX_PAGES`) with `extraction_mode="per-page"`, + `parallel_pages=4`, and both QA and challenge enabled (the worst-case option + combination), the arithmetic worked out in Task 9's report is: each of + `key_extractor` → `kv_qa` → `kv_challenger` fans 100 pages across 4 workers (25 + sequential rounds), each round up to ~99s if its slowest call needs a *full* retry + backoff (`SDKLLMClient`'s `_DEFAULT_MAX_RETRIES=8`) — 25 × 99s = 2,475s per stage, + 3 stages sequential = **7,425s**, a gap of **3,825s (over 2x)** against the real + 3,600s baseline, not the 225s a 7,200s baseline would suggest. That 7,425s figure + assumes every single call across all 300 (100 pages × 3 stages) hits the full + 8-retry backoff, which is not realistic — a real call is ~10-30s, so a full run at + the page cap is closer to **~2,000-2,500s** in practice; the 7,425s number is a + theoretical ceiling for capacity planning, not an expected duration. + **Recommendation: do not raise the fleet-wide time limit preemptively.** + `EXECUTOR_TASK_TIME_LIMIT` is fleet-wide — every executor task (every plugin, not + just Agent-KV) inherits it, and it's coupled to `workerPgExecutor`'s PG-visibility + lease/`vt` and `terminationGracePeriodSeconds` (raising one without the others + reintroduces the mid-flight-SIGKILL/silent-redelivery risk `UN-3964`'s comment on + `workerExecutorV2` already guards against). Measure real per-page timings from the + Task 13 integration run first, then either raise `EXECUTOR_TASK_TIME_LIMIT` (and + `terminationGracePeriodSeconds`/the PG lease together, not alone) or lower + `AGENT_KV_MAX_PAGES` for deployments that see per-page-heavy, near-cap documents in + practice. + + **What actually happens at each limit.** At the **soft** limit (3,300s) Celery raises + `SoftTimeLimitExceeded` into the task; the executor catches it, sets a run-level stop + signal that makes every in-flight LLM retry loop abort at its next backoff instead of + sleeping through the remaining ladder (up to ~30s per attempt × 8 attempts), flushes + the usage records accrued so far, and finalizes the job `failed` with the user-safe + error `"timed out"`. At the **hard** limit (3,600s) the worker is SIGKILLed: usage + records still held in memory are lost, so that run's LLM spend goes **unmetered** + (page usage, posted per-OCR-call, is unaffected). That gap is the reason the soft + limit now stops retries promptly — it is what keeps a slow run from crossing into the + hard kill. +10. **Testing lanes — Docker-free unit gate, Docker-required integration lane.** The + cloud rig's `unit-agentic-kv` group (`tests/groups.cloud.yaml`, cloud repo) runs the + executor plugin's own test suite in an isolated venv with no `requires_services` — + no Docker needed, and it's what `tox -e unit` (CI's unit-tier matrix leg) runs. The + integration tier is the one that needs Docker: it authenticates to the container + registry and boots a mock Auth0 sidecar (`.github/workflows/ci-test.yaml`, cloud + repo) for the cross-service suites. A local `unit-agentic-kv` run needs neither + Docker nor the platform stack up. + + **A real-key Agent-KV e2e run cannot go through `tests.rig run`.** Whenever a + selected group needs the platform, the rig sets `UNSTRACT_LLM_MOCK_RESPONSE` + to `MOCK_LLM_OK` (`tests/rig/cli.py`) — and an exported *empty* value counts as + unset, so there is no way to opt out from inside the rig; the lane then exercises + the mock, not a provider. To run it against real LLMWhisperer/LLM keys, boot the + stack first (`python -m tests.rig platform up`, or `docker compose` with + `tests/compose/docker-compose.test.yaml`) and then invoke pytest directly with + `UNSTRACT_BACKEND_URL`, `AGENT_KV_E2E=1` and the `AGENT_KV_*` keys exported: + `AGENT_KV_E2E=1 UNSTRACT_BACKEND_URL=http://localhost:8000 pytest tests/e2e/agent_kv`. + + Two scenarios are operator-gated on top of that: the bad-LLM-key scenario + (`AGENT_KV_E2E_BAD_KEY_JOB=1`, see the test module docstring) and the + completion-webhook scenario, which needs + `AGENT_KV_WEBHOOK_INSECURE_ALLOW_HTTP_PRIVATE=1` set BOTH on the + ide-callback worker (it waives the webhook SSRF guards — https scheme + + public host — for test/dev stacks only; never set it in production) and in + the pytest process env; the receiver is reached via + `host.docker.internal` (the compose host-gateway mapping). The lane also + covers sync-wait submits (`timeout` → 200 with the inline result) and an + `.xlsx` document (`fixtures/invoice.xlsx`, the no-pre-OCR-page-count path). +11. **Sandbox worker — calculations codegen fleet** (when + `AGENT_KV_CALCULATIONS_ENABLED=true`). The optional `calculations` field + invokes out-of-process codegen and execution in a dedicated sandbox worker fleet + consuming the `sandbox_codegen` Celery queue. **Deployment order is strict:** + deploy the sandbox worker (Deployment healthy, actively consuming tasks from + `sandbox_codegen`) **before** flipping `AGENT_KV_CALCULATIONS_ENABLED=true`. + With the flag on but the sandbox down, calculation jobs fail user-safely at the + RPC timeout (they do not hang past it); however, **never leave the flag on + without a healthy sandbox fleet**, as all jobs with `calculations` will eventually + exceed their timeouts and return failures to callers. + + **Security posture:** The sandbox pod carries no LLM, OCR, or storage secrets and + runs with default-deny egress — it only executes generated calculation code against + the extracted record in-memory. This no-secrets/deny-all-egress posture is the + **Kubernetes/chart deployment guarantee**. The reference `docker-compose.yaml` + included here is a best-effort dev mirror only, not that guarantee: its + `worker-sandbox` service shares the same full worker env-file (`workers/.env`) as + every other worker for operational simplicity, so on that stack the untrusted-code + boundary is the runner's per-subprocess env scrub (spec §6.3 layer 2), not full + pod-level secret isolation — don't run untrusted `calculations` against secrets you + care about on docker-compose. User-supplied `calculations` expressions are + validated through an AST gate (layer 1 of a 5-layer defense-in-depth model) at + submit time before ever reaching the sandbox, and further constrained (parsing, + type-checking, capability allowlist) at execution time. The AST gate is a + **best-effort** layer-1 control — a fail-closed denylist that closes the cheap, + demonstrated bypasses and raises the cost of the rest, not a provably airtight + sandbox by itself. The *enforced* containment is layers 2–5: the runner's + env-scrub + rlimits (layer 2) and the pod's non-root/read-only-rootfs/no-secrets/ + deny-all-egress/per-job isolation (layers 3–5), with `runtimeClass: gvisor` as the + deferred syscall-sandbox mitigation (see the accepted v1 residual below). Do not + treat an AST-gate pass alone as proof generated code is safe. + + **Accepted v1 residual (in-pod file reads):** because generated code + legitimately needs the `open()` builtin for its input and output files, untrusted + calculation code can read a world-readable file inside its own sandbox pod and + return the contents to the submitter. The import allowlist is exactly `{json, math, + statistics, decimal, datetime, re, collections, itertools, functools, sys}` — + `pathlib`, `os`, `io`, `socket` and `urllib` are all outside it, so this is a single + read of a known path, not directory traversal and not an exfiltration path. This is contained — not by the AST gate, but + by the pod's layers 2–5: no secrets in the pod (not even the platform + `ENCRYPTION_KEY`), non-root on a read-only rootfs, default-deny egress (no + exfiltration), per-job isolation, and results returned only to the submitting + key — so the worst case is disclosure of a non-sensitive container file to the + customer who submitted the job. The deferred hardening for this is a + `runtimeClass: gvisor` sandbox. Consequently the sandbox pod's default-deny egress + and no-secrets posture are load-bearing and must not be relaxed. + +## 13.

Security model in brief + +Premise: **the document, `keys.json`, `key_notes`, and `calculations` are all +attacker-controlled**, and they flow into prompts and generated code. The full model is +[design §6](superpowers/specs/2026-08-28-agent-kv-api-design.md); the codegen sandbox is +the load-bearing control. + +**The sandbox's five layers** (all enforced server-side in `workers/sandbox/`, never +trusting the client): +1. Fail-closed **AST gate** (import allowlist + denylisted calls/attrs/dunders). +2. **Scrubbed-env subprocess** — empty environment, minimal PATH, per-request tempdir, + `-I -S -E`, `start_new_session`, rlimits (CPU/mem/NPROC/NOFILE/FSIZE), process-group + kill at `timeout + grace`. +3. **Hardened pod** — non-root, read-only rootfs + `emptyDir` /tmp, all caps dropped, + `seccompProfile: RuntimeDefault`, no service-account token, CPU/mem/PID limits. +4. **NetworkPolicy** — default-deny ingress+egress; egress only to broker, Postgres, DNS. + No object store, no platform-service, no backend, no internet. +5. **No secrets** in the pod beyond its own broker/result-backend DB credential — and + critically **not** the platform master `ENCRYPTION_KEY`. + +The sandbox receives only `{record JSON + generated code}` — no document, no schema, no +tenant identifiers; output is validated JSONL, row- and byte-capped. + +**Accepted v1 residual (R12) — CORRECTED.** Generated code legitimately needs the +`open()` builtin (it reads its input JSON and writes its output JSONL), so it can read +files in its own pod and return them to the submitting customer. + +An earlier version of this paragraph described that residual as *"a single read of a +known path … non-sensitive … not an exfiltration path"*, contained by a layer-3 +*"no secrets"* invariant. **Both halves of that are false, verified by execution**, and +this is the text an admin signs off against, so it is corrected here independently of +when the hardening lands: + +- **It reaches credentials, not a benign file.** The sandboxed child runs as the *same + UID* as the worker process, so `open('/proc//environ')` returns the worker's + full environment — including `DB_PASSWORD`. No import is needed: `open()` alone is + enough, so the allowlist (`pathlib`/`os`/`io`/`socket`/`urllib` all outside it) does + not bound this. +- **The "no secrets" invariant does not hold for this pod.** `workerPgSandbox.additionalConfigs` + is `[database]` — on the PG transport the queue *is* Postgres, so the pod must mount + `DB_HOST/DB_USER/DB_PASSWORD/DB_NAME`. Combined with the NetworkPolicy permitting + egress to db-proxy:5432 (it must, for the same reason), the recovered credential is + **directly usable**, and in cloud staging `DB_USER` is `postgres`. +- **The AST gate is not a second line of defence here.** It is bypassable + (`statistics.random._os.system(...)`, `collections._sys._getframe(0).f_builtins[...]` + — allowlisted modules re-export `sys`/`os` as non-dunder attributes the gate never + inspects), so it should be read as best-effort hygiene, not containment. + +**So the true worst case is credential disclosure plus database reach beyond the job's +own input**, not disclosure of a non-sensitive container file. What still contains it is +narrower than claimed: read-only rootfs, non-root, per-job tempdir, default-deny egress +*except* Postgres and DNS, and results returned only to the submitting key. Egress +default-deny remains load-bearing; "no secrets" must not be cited as an invariant for +this pod until the credential is actually removed from it. + +Required mitigation (not deferred): a narrowly-scoped queue/result DB role, so the +credential the pod carries cannot read beyond its own job — tracked as **UN-4218**, +alongside a numeric `runAsUser` and `/proc` hardening. Deferred mitigation: +`runtimeClass: gvisor`. Full analysis in +[sandbox design §8a](superpowers/specs/2026-09-01-agent-kv-sandbox-worker-design.md). + +Other boundaries: view-owned auth with per-endpoint 401 tests; UUID4 job ids + org-scoped +lookups (IDOR → 404); webhook SSRF controls (private/link-local/metadata ranges refused, +re-checked at connect time, no redirects, `{job_id, status}` body only); org-scoped cache +key (cross-tenant reuse structurally impossible); fail-closed billing admission. + +## 6. Runtime & configuration essentials + +- **Sandbox image (v1):** runs from the existing `worker-unified` image with command + `sandbox` (a dedicated stdlib-only slim image is a deferred upgrade). The security + guarantees come from the scrubbed subprocess + pod hardening, not image contents. +- **`calculations` GA flag:** `AGENT_KV_CALCULATIONS_ENABLED=true`. Off degrades cleanly + (submit rejects `calculations`; nothing dispatches mid-pipeline). +- **Object storage:** `FileStorageType.AGENT_KV`, org-rooted at + `{AGENT_KV_STORAGE_DIR_PREFIX}/{org_id}/{job_id}/` (default prefix `unstract/agent_kv`); + the first path segment is the bucket — backend and executor **must** share the value. +- **Celery result backend (`CELERY_BACKEND_DB_*`):** required for the sandbox request-reply + path. Cloud supplies it via the chart secret; dev must set it (the compose rig wires it + to Postgres). +- Full env matrix: [`docs/agent-kv-api.md` §13](agent-kv-api.md); deploy order and the + chart's four hard-coded storage-secret sites: [§12](agent-kv-api.md). + +## 7. Current status + +- **Built & reviewed:** both sub-projects complete; a pre-Greptile review fixed 5 Critical + + ~18 Important findings (gate bypasses, schema depth/recursion DoS, a finalize + data-loss race, a slot leak, status casing, engine array-drop, model-ID defaults). +- **Proven live (docker-compose, real-HTTP curl, 2026-09-02):** submit → poll → result + with array rows preserved and a calculation computed out-of-process + (`line_count: 3, amount_total: "482.50"`); `calculations_applied: true`, + `execution.success: true`; sandbox held read-only rootfs with 0 restarts; auth negatives + (no key / bad key → 403); schema-DoS guard (600-deep schema → `200 valid:false "exceeds + max_depth=6"`, zero 500s). Reproduce with the scratch `curl-smoke.sh` recipe. +- **Wire format is extractor-scoped** (2026-09-10, spec §7.0): a submit carries + `extractors: [{name, keys, options}]` rather than flat top-level knobs, and status and + result are keyed by extractor. Done before launch precisely because it could not be + done after — see the deliberate divergence from APS v2's composition model recorded in + §7.0. Currently one extractor (`kv`) is accepted; the format is in place for + multi-extractor jobs, the fan-out execution is not. +- **Not yet validated:** a real **Kubernetes** deploy. The chart, the NetworkPolicy-based + sandbox containment, the minimal Secret, and the sandbox result-backend wiring are + helm-unittest-rendered but never applied to a cluster. **This is the one outstanding + validation before production.** +- **Branch state:** all fix commits (plus this overview) are **committed and pushed** on + both branches — OSS `Feat/agent-kv-api`, cloud `UN-4044-agent-kv-cloud-executor`; + **no PR raised yet** (both must pass Greptile first). +- **Not started:** the fail-closed billing admission gate + Stripe invoicing (see + **Billing & metering** below); migrating `agentic_table` onto this shared sandbox. + +### Billing & metering + +**Usage recording — built and wired** (rides the platform's standard usage pipeline): +- **LLM token/cost usage:** the executor flushes each LLM's pending usage exactly-once into + `metadata.usage_records`; the generic executor task harvests them → + `usage_client.bulk_create_usage(...)` → `POST v1/usage/batch/`. +- **OCR page usage:** `PageUsagePoster` → `Audit().push_page_usage_data(...)` + (platform-service), which fires the subscription hook — the same path + `unstract.sdk1.x2txt.X2Text` uses. +- **Per-job snapshot:** `usage_summary = {pages, input_tokens, output_tokens, total_cost, + agents}` stored on `AgentKVJob`; `total_cost` is the authoritative billing figure. +- **Status:** unit-tested and runs whenever a job completes; asserting a `usage_v2` row + end-to-end is a staging check (not separately asserted in the compose run). + +**Subscription admission — built** (2026-09-10, following the API deployment path): +`SubmitView` gates on the org's subscription via the cloud plugin's `service_class`, +reusing the same `SubscriptionHelper` policy cloud's `SubscriptionMiddleware` applies to +`/deployment/api/...` — same 402 bodies, no restatement. It runs in the view rather than +that middleware because Agent-KV's URL has no org segment for the middleware to resolve +from, so it resolved `None` and admitted everything. Expired trial or inactive +subscription → **402**, nothing dispatched or billed. + +**Not built — deferred to the billing sub-project:** +- **Spend reservation.** The gate checks subscription *status*, not budget: an org inside + a valid subscription can still run unlimited jobs. Unstract enforces no spend + reservation anywhere, so matching the platform means not inventing one here. +- **No-subscription-row orgs are admitted**, matching the middleware exactly (and + differing from `validate_etl_run`, which denies).
