+name: Performance Regression
+about: Report a backend latency regression, memory leak, or throughput degradation
+title: 'Perf: [Short description of performance regression]'
+labels: 'type: perf, scope: backend, status: needs-triage'
+assignees: 'YieldVault-RWA/backend-maintainers'
+---
+
+## ⚡ Summary
+Provide a concise overview of the performance regression, when it was detected, and its impact on backend latency, throughput, or resource consumption.
+
+## 🎯 Endpoint & Scope
+- **Endpoint**: e.g. `POST /api/v1/vault/deposit` or `GET /api/v1/transactions`
+- **Component Scope**: `scope: backend`
+- **Environment**: Production / Staging / Testnet / Local
+- **Deployment / Commit**: e.g. `sha-abcdef1` or `v1.4.2`
+
+## ⏱️ Latency & Performance Metrics (p95 before/after)
+- **p95 Before**: e.g. `45 ms` (historical baseline)
+- **p95 After**: e.g. `380 ms` (observed degraded latency)
+- **p99 Before / After**: e.g. `80 ms` / `750 ms`
+- **Memory / CPU Impact**: e.g. Node process memory grew from 250MB to 1.8GB (suspected memory leak)
+
+## 🚦 Traffic & Load (QPS)
+- **QPS**: e.g. `250 req/s` (or traffic rate during regression)
+- **Concurrency**: e.g. `50 concurrent connections`
+
+## 🎯 Expected SLO
+- **Expected SLO**: e.g. `Read P95 < 200 ms` / `Write P95 < 500 ms` (as defined in `docs/api/SLA_SLO.md` and `docs/nfr-baselines.json`)
+- **Error Budget Impact**: e.g. Consuming 15% of monthly error budget / SLO breach
+
+## 🗄️ DB Query Plan
+Attach the `EXPLAIN ANALYZE` execution plan, Prisma query trace, or slow query log below:
+
+```sql
+-- Paste EXPLAIN ANALYZE or slow query plan here
+```
+
+## 🔄 Repro Steps
+1. Configure load generator or HTTP client:
+2. Execute command or load script (e.g. `k6 run load-test.js` or `autocannon -c 50 -d 30s <endpoint>`):
+3. Send payload:
+4. Observe latency metric spike or memory growth in metrics dashboard:
+
+## 📊 Profiling & Diagnostic Evidence
+- **Flamegraph / Profiler Trace**: (Attach SVG or link to CPU flamegraph/pprof trace)
+- **Heap Snapshot / Memory Profile**: (Attach snapshot or leak analysis)
+- **Grafana / Prometheus Dashboard Link**:
+- **APM Trace IDs / OpenTelemetry Span**:
+
+## 📝 Additional Context
+Include any relevant recent PRs, schema migrations, database index changes, third-party RPC bottlenecks, or potential root cause hypotheses.

 ## 🔗 Type of Change
 - [ ] 🐛 Bug fix (non-breaking change that fixes an issue)
 - [ ] ✨ New feature (non-breaking change that adds functionality)
 - [ ] ⚠️ Breaking change (fix or feature that would cause existing functionality to change)
-- [x] 📚 Documentation update
+- [ ] 🌊 Wave submission (contract migration, architectural wave release, or protocol upgrade)
+- [ ] 📚 Documentation update
 - [ ] 🔒 Security improvement
+- [ ] ⚡ Performance optimization
+
+---
+
+## 🛡️ Risk Assessment
+
+<!-- Mandatory for all PRs to evaluate blast radius, particularly contract migrations & Wave submissions -->
+
+### Risk Level
+- [ ] 🟢 **Low**: Non-breaking change, documentation, style, or isolated helper refactoring
+- [ ] 🟡 **Medium**: API enhancement, frontend workflow update, non-critical dependency upgrade
+- [ ] 🟠 **High**: Core contract logic change, access control modification, financial accounting / share math
+- [ ] 🔴 **Critical**: Wave submission, contract storage migration, protocol upgrade touching vault funds
+
+### Blast Radius & Impact Analysis
+- [ ] Contract storage layout / data key migration involved
+- [ ] Value transfer, deposit/withdraw flow, or vault share calculation affected
+- [ ] External integration (Oracle, Soroban RPC, Bridge, Token contract) affected
+- [ ] Database schema migration or data backfill required
+- [ ] Breaking API or interface change affecting downstream clients
+- [ ] Zero blast radius (isolated tooling / documentation only)
+
+**Detailed Risk & Blast Radius Notes:**
+<!-- Describe specific failure modes, edge cases, affected components, and risk mitigations -->
+```
+```
+
+---
+
+## 🔄 Rollback Plan
+
+<!-- Detail the exact steps and strategy to revert this change if unexpected failures occur in production -->
+
+### Rollback Strategy & Feasibility
+- [ ] **Clean Git Revert**: Revertable with zero persistent state drift
+- [ ] **Contract Upgrade Rollback**: Tested rollback to previous contract WASM hash / implementation
+- [ ] **Database Migration Revert**: Reversible migration down-script tested and verified
+- [ ] **Feature Flag / Circuit Breaker**: Feature can be toggled off instantly without redeployment
+- [ ] **Emergency Pause**: Contract pause / freeze mechanism available to halt affected functions
+- [ ] **Forward-Only / Irreversible**: State migration cannot be cleanly reversed; emergency recovery runbook linked below
+
+### Rollback Trigger Criteria
+<!-- What specific conditions, metrics, or alerts will trigger an immediate rollback? (e.g. error rate > 1%, oracle divergence, tx reverts) -->
+- 
+
+### Step-by-Step Rollback Procedure
+<!-- List the exact operational sequence required to execute a rollback -->
+1. 
+2. 
+3. 
+
+---
+
+## ⚡ Performance Impact
+
+<!-- Evaluate gas usage, execution compute units, latency, throughput, and bundle size impact -->
+
+### Performance & Resource Assessment
+- [ ] Smart contract gas / compute units benchmarked (no regression > 5%, or justified below)
+- [ ] Backend API latency (p95/p99) and database query execution plans verified
+- [ ] Database indexing verified for newly queried columns (no table scans)
+- [ ] Frontend bundle size and Time to Interactive (TTI) verified
+- [ ] Memory allocation and leak checks verified (no memory leaks in long-running services)

+# Security Review Checklist — Secrets, PII & Transport
+
+**Use for:** any PR that adds/changes a data store, secret, credential, external integration, or network-facing endpoint.
+**Companion doc:** [`docs/security/encryption-review.md`](../docs/security/encryption-review.md) — full current-state review this checklist enforces going forward.
+**Not this checklist:** smart-contract vulnerability classes (reentrancy, access control, gas/DoS) are covered by [`docs/SECURITY_CHECKLIST.md`](../docs/SECURITY_CHECKLIST.md).
+
+---
+
+## 1. Secrets & Credentials
+
+- [ ] No secret, API key, private key, or credential is hardcoded or committed (checked by `gitleaks` in CI, but review the diff yourself too)
+- [ ] New secrets are read from `process.env` / GitHub Actions `secrets.*`, never from a config file checked into the repo
+- [ ] Any new required secret is documented in [`docs/ENV_VARIABLE_MATRIX.md`](../docs/ENV_VARIABLE_MATRIX.md)
+- [ ] Secrets that must exist in production fail startup loudly if missing or weak (follow the pattern in `backend/src/auth.ts`'s `assertJwtSecretValid()`) rather than silently falling back to a dev default
+- [ ] Tokens/keys are persisted as one-way hashes (SHA-256/HMAC or stronger), never in plaintext
+
+## 2. Data at Rest
+
+- [ ] New sensitive fields (PII, tokens, wallet-linked identifiers) are added to the correct model with the retention category noted in [`docs/DATA_RETENTION_DELETION_POLICY.md`](../docs/DATA_RETENTION_DELETION_POLICY.md)
+- [ ] Any new database, cache, or file-based store this PR introduces is confirmed to write to the *intended* backing store — verify the Prisma datasource / connection string actually points where you think it does (see `docs/security/encryption-review.md` §4 F1 for a real example of this silently going wrong)
+- [ ] No secret or PII value is written to logs, error messages, or audit trails in plaintext — check against `backend/src/auditRedaction.ts`'s redaction patterns
+
+## 3. Data in Transit
+
+- [ ] All new outbound calls (webhooks, RPC, third-party APIs) use `https://` / `wss://`, never plaintext `http://`
+- [ ] New database or cache connection strings enforce TLS (`sslmode=require` for Postgres, `rediss://` for Redis) where the backing service supports it
+- [ ] New cookies (if any) set `Secure`, `HttpOnly`, and an explicit `SameSite` — this repo's auth model currently uses Bearer tokens, not cookies, so introducing a cookie is a deliberate change worth flagging in the PR description
+- [ ] CORS changes stay within an explicit origin allowlist — no `*` or broad regex in `CORS_ALLOWED_ORIGINS`
+
+## 4. PII & Sensitive Data Handling
+
+- [ ] User-identifying data (wallet address, email, IP) is only collected/stored where there's a documented purpose in [`docs/DATA_RETENTION_DELETION_POLICY.md`](../docs/DATA_RETENTION_DELETION_POLICY.md)
+- [ ] Frontend `localStorage`/`sessionStorage` usage stores no private keys, JWTs, or API keys — only public/non-sensitive values (wallet address, UI prefs, session timestamps)
+- [ ] New admin or export endpoints that expose PII/financial data are gated by the correct RBAC role and rate-limited
+
+## 5. If This PR Touches Any of the Findings in `docs/security/encryption-review.md`
+
+- [ ] Confirm which finding (F1–F6) this PR addresses, if any
+- [ ] Update the finding's status in `docs/security/encryption-review.md` in the same PR
+- [ ] If this PR resolves a finding, note it in the PR description so reviewers can verify against the documented evidence
+
+---
+
+**If any box above cannot be checked**, explain why in the PR description rather than leaving it silently unchecked — a documented exception is reviewable; a missing explanation is not.

+# Observability & Auth Enhancement Spec
+
+## Overview
+Improve system reliability and user security through enhanced distributed tracing, slow query monitoring, and secure session management.
+
+## Features
+
+### 1. Distributed Request Tracing
+**Goal:** Make multi-step request debugging easier with clear correlation identifiers.
+
+**Problem:** Without correlation IDs across all layers, debugging multi-step requests requires manually correlating logs across services.
+
+**Acceptance Criteria:**
+- Request IDs added to all API requests and propagated through middleware
+- Trace IDs included in logs and error responses
+- Correlation IDs propagated to downstream calls (webhooks, external services)
+- Tracing metrics available in operational dashboards
+- Integration tests validate trace propagation
+
+**Scope:**
+- Enhance existing correlationId middleware with trace context propagation
+- Add span attributes for request paths, user context, tenant boundaries
+- Document trace format for operational teams
+- Add tests for trace context propagation across async operations
+
+### 2. Slow Query Monitoring & Alerting
+**Goal:** Identify expensive requests before they affect production reliability.
+
+**Problem:** Slow database queries can quietly degrade user experience without visibility into the root cause.
+
+**Acceptance Criteria:**
+- Query execution time measured for all database operations
+- Alerts triggered when queries exceed configured thresholds
+- Slow query logs surfaced in operational tooling (structured logs, metrics)
+- Common bottlenecks identifiable through dashboard queries
+- Performance budget breach severity (warning vs critical) configurable per query
+
+**Scope:**
+- Extend existing queryBudgets module with structured alert delivery
+- Add metrics for query duration distribution and breach frequency
+- Implement alert rate limiting to prevent storms
+- Create operational dashboard queries for slow query analysis
+- Add monitoring documentation for ops teams
+
+### 3. Secure Session & Token Management
+**Goal:** Make auth sessions safer and easier to recover from.
+
+**Problem:** Session expiration and token refresh flows can become confusing or insecure without solid handling.
+
+**Acceptance Criteria:**
+- Refresh token lifecycle follows secure rotation rules
+- Tokens revoked immediately on logout or suspicious activity
+- Expiration and reuse errors tracked and logged clearly
+- Tests cover expired, rotated, and invalid token flows
+- Session recovery procedures documented
+
+**Scope:**
+- Enhanced refresh token rotation with audit trail
+- Token revocation list with efficient lookups
+- Replay attack detection and response
+- Redis-backed session store for multi-instance deployments
+- Comprehensive test suite for token flows
+- Session recovery documentation
+
+### 4. Contract Work: Max Exposure Guardrails
+**Goal:** Ensure strategy allocation respects maximum exposure limits in production-hardened way.
+
+**Problem:** Current implementation doesn't fully cover this capability with proper testing and documentation.
+
+**Acceptance Criteria:**
+- Implementation completed with comprehensive validation logic
+- Unit tests added for guardrail calculations
+- Integration tests validate multi-vault exposure limits
+- E2E tests confirm UI reflects exposure constraints
+- Documentation updated with exposure model and limits
+- CI checks pass with no regressions
+
+**Scope:**
+- Add or enhance exposure validation in strategy allocation
+- Implement guardrails for per-vault and cross-vault exposure
+- Add metrics and alerts for exposure threshold breaches
+- Document exposure constraints for product and ops teams
+
+## Implementation Sequence
+1. **Phase 1:** Distributed tracing enhancements (req #1)
+2. **Phase 2:** Slow query monitoring (req #2)
+3. **Phase 3:** Session & token management (req #3)
+4. **Phase 4:** Contract work on exposure guardrails (req #4)
+
+## Success Metrics
+- All acceptance criteria met for each feature
+- No regressions in existing tests
+- Comprehensive test coverage (unit, integration, e2e)
+- Documentation complete and reviewed
+- Operational runbooks created for monitoring and incident response

+
+## Testing Strategy
+
+### Unit Tests (to implement)
+- Correlation ID generation and propagation
+- Alert delivery with different channels
+- Token revocation and validation
+- Session audit logging
+- Exposure calculation and validation
+
+### Integration Tests (to implement)
+- Trace context across async operations
+- Query monitoring with budget breaches
+- Token refresh flow with concurrent requests
+- Suspicious activity detection patterns
+- Exposure limits with multi-vault scenarios
+
+### E2E Tests (to implement)
+- Complete allocation flow with exposure checks
+- Session lifecycle (login → refresh → logout)
+- Multi-step requests with trace propagation
+- Slow query alert delivery
+
+## Known Limitations & Future Work
+
+### Current Scope
+- ✓ Trace context at API boundary
+- ✓ Query budget enforcement
+- ✓ Token revocation storage (Redis optional)
+- ✓ Basic suspicious activity detection
+
+### Future Enhancements
+- [ ] Automated query optimization recommendations
+- [ ] Machine learning for anomaly detection
+- [ ] Advanced portfolio risk calculations
+- [ ] Integration with external risk management systems
+- [ ] Enhanced CAC (cross-asset correlation) analysis
+
+## Rollback Plan
+
+**If critical issues found:**
+
+1. **Revert branch:**
+   ```bash
+   git revert -n <commit-hash>
+   git commit -m "Revert observability implementation"
+   ```
+
+2. **Disable features via environment:**
+   ```bash
+   OTEL_ENABLED=false
+   SESSION_MANAGEMENT_ENABLED=false
+   EXPOSURE_GUARDRAILS_ENABLED=false
+   ```
+
+3. **Audit affected operations:**
+   - Check audit logs for any session issues
+   - Review allocation history for rejected valid requests
+   - Verify API response times during revert

 # Contributing to YieldVault-RWA
 
-First off, thank you for considering contributing to YieldVault-RWA! It's people like you that make this project great.
+Welcome to the YieldVault-RWA project. This guide outlines how to set up your environment, follow our contribution workflow, and engage with the review process.
 
-## Secret Scanning & Prevention
+## Table of Contents
 
-This repository uses **gitleaks** to prevent accidental commits of secrets (API keys, private keys, passwords, etc.).
+- [Setup](#setup)
+- [Development Workflow](#development-workflow)
+- [Branching Strategy](#branching-strategy)
+- [Testing Requirements](#testing-requirements)
+- [Pull Request Process](#pull-request-process)
+- [Review Expectations](#review-expectations)
+- [Release Cycle](#release-cycle)
 
-### Pre-commit Hook
+## Setup
 
-A pre-commit hook runs automatically before each `git commit` to scan for secrets in staged files. If secrets are detected, the commit will be blocked.
+### Prerequisites
 
-#### Installation
+- Node.js 18+ (for backend)
+- Rust 1.70+ (for WASM/contracts)
+- Docker (for local database and services)
+- Git
 
-The pre-commit hook is already configured via **Husky**. When you clone the repository:
+### Initial Setup
 
 ```bash
-# Install dependencies (includes husky setup)
-npm install
+# Clone the repository
+git clone https://github.com/yourusername/YieldVault-RWA.git
+cd YieldVault-RWA
+
+# Install dependencies
+npm ci               # Backend
+cd frontend && npm ci # Frontend
 ```
 
-The hook is located at `.husky/pre-commit` and runs `scripts/secrets-check.js`.
+### Environment Configuration
 
-#### Manual Setup (if needed)
+Copy environment templates and configure for local development:
 
 ```bash
-# Install husky
-npm install husky --save-dev
+# Backend
+cp backend/.env.example backend/.env.local
+# Edit backend/.env.local with your local settings
 
-# Initialize husky
-npx husky init
+# Frontend
+cp frontend/.env.example frontend/.env.local
+```
+
+See [ENVIRONMENT_VARIABLES.md](./backend/docs/ENVIRONMENT_VARIABLES.md) for detailed configuration.
 
-# Create the pre-commit hook
-echo 'node scripts/secrets-check.js' > .husky/pre-commit
+### Database Setup
 
-# Configure git to use husky hooks
-git config core.hooksPath .husky
+```bash
+cd backend
+npm run prisma:migrate:dev
+npm run prisma:seed  # Optional: seed test data
 ```
 
-#### Bypassing the Hook (Use with Caution)
+### Running Locally
 
-If you encounter a false positive, you can bypass the hook:
 ```bash
-git commit --no-verify -m "Your commit message"
+# Backend (from project root)
+npm run dev:backend
+
+# Frontend (from project root)
+npm run dev:frontend
+
+# Both (from project root)
+npm run dev
 ```
 
-**⚠️ Never bypass the hook for actual secrets!**
+## Development Workflow
 
-#### What the Hook Detects
+### Before You Start
 
-The hook scans for common secret patterns including:
-- AWS Access Keys and Secret Keys
-- GitHub Personal Access Tokens
-- Private Keys (RSA, EC, DSA)
-- API Keys and Secret Tokens
-- Passwords in code
-- Bearer Tokens and JWTs
-- Stripe API Keys
-- Slack Tokens
-- Database connection strings
+1. Check the [Roadmap](#roadmap) to understand current priorities
+2. Review existing issues and pull requests to avoid duplication
+3. Ask in discussions if your feature is significant or aligns with current direction
 
-### GitHub Secret Scanning
+### Branching Strategy
 
-GitHub's built-in secret scanning is enabled on this repository. When secrets are pushed to the repository:
+We follow a modified Git Flow:
 
-1. GitHub will alert you via the Security tab
-2. Alerts are routed to the security team based on repository settings
-3. Push protection blocks commits containing known secret patterns
+- **main**: Production-ready code. Protected branch; all changes via PR.
+- **staging**: Pre-production testing. Staging deployments automatically trigger from this branch.
+- **feat/\***: Feature branches for new functionality
+  - Branch from: `main`
+  - Format: `feat/kebab-case-description`
+  - Example: `feat/add-withdrawal-orchestration`
 
-To configure secret scanning alerts:
-1. Go to **Repository Settings** → **Security** → **Secret scanning**
-2. Review and configure alert notifications
+- **fix/\***: Bug fix branches
+  - Branch from: `main`
+  - Format: `fix/kebab-case-description`
+  - Example: `fix/referral-accrual-calculation`
 
-## Branch Naming Convention
+- **docs/\***: Documentation-only changes
+  - Branch from: `main`
+  - Format: `docs/kebab-case-description`
+  - Example: `docs/query-optimization-guide`
 
-To keep our repository organized, we follow a strict branch naming convention. Please name your branch according to the type of work you are doing:
+- **chore/\***: Dependency updates, refactoring, tooling
+  - Branch from: `main`
+  - Format: `chore/kebab-case-description`
+  - Example: `chore/upgrade-prisma`
 
-- **Features**: `feat/<issue-number>-<short-description>`
-  - Example: `feat/349-add-user-login`
-- **Bug Fixes**: `fix/<issue-number>-<short-description>`
-  - Example: `fix/350-resolve-auth-crash`
+### Creating Your Branch
 
-## Issue Reporting Conventions
+```bash
+git fetch origin
+git checkout -b feat/your-feature-name origin/main
+```
 
-When opening a new issue, please use the most appropriate template so the report is actionable for triage:
+## Testing Requirements
 
-- **Bug reports**: use the Bug Report template for defects, crashes, regressions, or unexpected behavior.
-- **Feature requests**: use the Feature Request template for new capabilities or enhancements.
-- **Security concerns**: use the Security Report template or follow the private security policy for sensitive vulnerabilities.
+### Before Submitting a PR
 
-## Pull Request Conventions
+All code changes require tests. We use:
 
-When submitting a Pull Request, please ensure the title is descriptive and follows the format of the issue. The PR body **must** include the following sections:
+- **Backend**: Jest for unit and integration tests
+- **Frontend**: Vitest for unit tests, Cypress for E2E tests
+- **Contracts**: Foundry/Hardhat tests for Solidity code
 
-### PR Title Format
-`<Type>: <Short description>`
-Examples:
-- `Feature: Add user login flow`
-- `Fix: Resolve authentication crash on mobile`
+### Running Tests Locally
 
-### Required PR Sections
+YieldVault-RWA is organized as a pnpm workspace monorepo. Tests can be run at the root workspace level or inside individual packages:
 
-Please use the following template for your PR description:
+#### Monorepo Root Commands: `pnpm test` vs `pnpm -r test`
 
-```markdown
-### Goal
-[Describe the goal of this PR and the problem it solves. Link to the relevant issue, e.g., "Closes #349".]
+- **`pnpm test`** (Root Workspace Pipeline): Runs the orchestrated test pipeline across all workspace packages with explicit production flags:
+  ```bash
+  pnpm test
+  # Executes: pnpm --filter backend test -- --runInBand --coverage && pnpm --filter frontend test --run
+  ```
+  - **Backend**: Runs Jest with `--runInBand` (serial worker execution to prevent concurrency collisions on SQLite) and collects coverage reports in `backend/coverage/`.
+  - **Frontend**: Runs Vitest with `--run` in deterministic single-pass mode.
 
-### Changes
-- [List out the specific changes made in this PR]
-- [Keep it concise but detailed enough for reviewers to understand the scope]
+- **`pnpm -r test`** (Recursive Package Run): Executes the `test` lifecycle script defined in each package (`backend`, `frontend`, `packages/api-schemas`) recursively in topological dependency order:
+  ```bash
+  pnpm -r test
+  ```
+  Package-level test scripts are aligned so that running recursively executes with the proper flags (`jest --runInBand --coverage` in backend and `vitest run` in frontend), guaranteeing that backend coverage artifacts are generated and frontend tests run non-interactively without hanging.
 
-### Testing
-- [Explain how the changes were tested]
-- [Include steps for reviewers to verify the fix/feature locally]
-```
+#### Running Tests in Individual Packages
 
-## Documentation
+```bash
+# Backend tests (runs Jest with --runInBand and --coverage)
+cd backend && pnpm test
+# Or from root:
+pnpm --filter backend test
 
-- **[Domain Glossary](./docs/GLOSSARY.md)** — Shared definitions for vault shares, APY, strategies, and other project terminology. Please use these terms consistently in code, comments, and documentation.
+# Frontend unit & component tests (runs Vitest in single-run mode)
+cd frontend && pnpm test
+# Or from root:
+pnpm --filter frontend test
 
-## Local Development Setup
+# Frontend watch mode (for active local development)
+cd frontend && pnpm test:watch
 
-YieldVault-RWA is composed of three main packages: Frontend, Backend, and Contracts. Follow the steps below to set up your local development environment end-to-end.
+# Frontend E2E tests (Playwright)
+cd frontend && pnpm test:e2e
 
-### Prerequisites
-- Node.js (v18+)
-- npm, pnpm, or yarn
-- Rust and Cargo (for contracts)
+# Cypress smoke tests
+cd frontend && pnpm test:cypress
+
+# Soroban smart contract tests
+cargo test -p vault
+```
+
+### Test Coverage Expectations
+
+- Unit tests: ≥80% line coverage for new code
+- Integration tests: Critical paths must be covered
+- E2E tests: Happy path and key user workflows
+
+### Linting and Formatting
 
-### 1. Contracts Setup
-The smart contracts are written in Rust.
 ```bash
-cd contracts
-# Install dependencies and build contracts
-cargo build
+# Backend
+cd backend && npm run lint
+npm run format
 
-# Run contract tests
-cargo test
+# Frontend
+cd frontend && npm run lint
+npm run format
 ```
 
-### 2. Backend Setup
-The backend handles API requests and application logic.
-```bash
-cd backend
-# Install dependencies
-npm install
+Code must pass linting before PR approval.
 
-# Set up your environment variables
-cp .env.example .env
+### Commit Messages
 
-# Start the backend development server
-npm run dev
-```
+Commit messages must use [Conventional Commits](https://www.conventionalcommits.org/) with a **lower-case** type drawn from this list:
+
+`fix` · `feat` · `chore` · `docs` · `test` · `refactor`
 
-### 3. Frontend Setup
-The frontend contains the user interface.
 ```bash
-cd frontend
-# Install dependencies
-npm install
+# Valid
+fix: correct rounding on share price accrual
+feat(frontend): add vesting schedule to dashboard
 
-# Set up your environment variables
-cp .env.example .env
+# Rejected — the type must be lower-case
+Fix: correct rounding on share price accrual
+FEAT: add vesting schedule to dashboard
+```
 
-# Start the frontend development server
-npm run dev
+The lower-case requirement is enforced by `commitlint.config.js` through the
+`.husky/commit-msg` hook, so an upper-case type is rejected at commit time. It
+also keeps the changelog correct: `cliff.toml` sets `conventional_commits = true`
+and groups release notes by parsed type, and git-cliff's parser accepts both
+cases. Without this rule `Fix:` would be parsed as its own type and split into a
+separate changelog group from `fix:`.
+
+To check a message without committing:
+
+```bash
+echo "Fix: something" | npx commitlint
 ```
 
-Thank you for your contributions!
+## Pull Request Process
 
-## Internationalization (i18n)
+### Before Opening a PR
 
-The frontend uses a lightweight custom i18n system located in `frontend/src/i18n/`.
+1. Ensure your branch is up-to-date with `main`
+2. Run all local tests and linting checks
+3. Verify your commit messages are clear and descriptive
 
-### How it works
+```bash
+git fetch origin
+git rebase origin/main
+npm run test
+npm run lint
+```
 
-- `frontend/src/i18n/index.ts` — exports `t(key)`, `useTranslation()`, `setLocale()`, and `getLocale()`.
-- `frontend/src/i18n/locales/en.ts` — English baseline catalog (source of truth).
-- `frontend/src/i18n/locales/es.ts` — Spanish catalog (mirrors the same nested key structure).
-- All visible UI strings must go through `t("some.key")` — no hardcoded strings in JSX.
+### Opening a PR
 
-### Adding a new locale
+Use our [PR template](./.github/PULL_REQUEST_TEMPLATE.md):
 
-1. **Create the catalog file** — copy `frontend/src/i18n/locales/en.ts` to `frontend/src/i18n/locales/<code>.ts` (e.g. `fr.ts`). Translate every leaf string. Keep the same nested key structure; do not add or remove keys.
+- **Title**: Clear, concise description of the change
+  - Format: `[area] description` (e.g., `[api] add withdrawal retry logic`)
+- **Description**: Explain what, why, and how
+- **Linked Issues**: Reference related issues with "Closes #123"
+- **Testing**: Describe test coverage and how to verify locally
+- **Screenshots**: Include for UI changes
 
-2. **Register the locale** in `frontend/src/i18n/index.ts`:
-   - Import your catalog: `import { fr } from "./locales/fr";`
-   - Add it to `catalogs`: `fr: fr as MessageTree,`
-   - Extend the `LocaleCode` union: `export type LocaleCode = "en" | "es" | "fr";`
-   - Add it to the `setLocale` guard: `if (code === "en" || code === "es" || code === "fr") { ... }`
+### PR Expectations
 
-3. **Add the locale to `LanguageSwitcher`** in `frontend/src/components/LanguageSwitcher.tsx`:
-   ```ts
-   const LOCALES: { code: LocaleCode; flag: string }[] = [
-     { code: "en", flag: "🇺🇸" },
-     { code: "es", flag: "🇪🇸" },
-     { code: "fr", flag: "🇫🇷" }, // ← add your entry
-   ];
-   ```
+- All CI checks must pass (tests, linting, security scans)
+- At least 1 approval from a code owner (see [CODEOWNERS](./.github/CODEOWNERS))
+- For sensitive changes (auth, secrets, dependencies): additional review required
+- Discussions must be resolved before merging
 
-4. **Add display labels** for the new locale in both `en.ts` and your new file:
-   ```ts
-   // en.ts
-   langSwitch: { en: "English", es: "Español", fr: "Français" }
+## Review Expectations
 
-   // fr.ts
-   langSwitch: { en: "English", es: "Español", fr: "Français" }
-   ```
+### Who Reviews
 
-5. **Verify** by switching to the new locale in Settings → Language & Region → App Language.
+- **Code Owners**: Automatically requested (see [CODEOWNERS](./.github/CODEOWNERS))
+- **Security**: Triggered for sensitive paths (see [SECURITY_REVIEW.md](./SECURITY_REVIEW.md))
+- **Teams**: Additional domain experts may be requested
 
-### Interpolation
+### Review Timeline
 
-Strings with dynamic values use `{{placeholder}}` syntax. Call `.replace()` at the call site:
+- Standard PRs: Review within 1 business day
+- Urgent/hotfixes: Review within 4 hours
+- Blocked/waiting PRs: Unblock within 1 business day
 
-```ts
-t("session.warning.message").replace("{{minutes}}", String(minutesLeft))
-```
+### What Reviewers Check
 
-### Using translations in components
+1. **Correctness**: Does the code do what it claims?
+2. **Tests**: Is coverage adequate? Do tests pass?
+3. **Performance**: Could this impact latency or throughput?
+4. **Security**: Does this introduce vulnerabilities? (See [SECURITY_REVIEW.md](./SECURITY_REVIEW.md))
+5. **Style**: Does it follow project conventions?
+6. **Documentation**: Are API changes documented?
 
-```tsx
-import { useTranslation } from "../i18n";
+### For Reviewers
 
-function MyComponent() {
-  const { t, locale, setLocale } = useTranslation();
-  return <p>{t("some.key")}</p>;
-}
-```
+- Be constructive and respectful
+- Distinguish between blocking and non-blocking feedback
+- Approve when satisfied with the quality
+- Use "Request Changes" only for critical issues
 
-For non-React contexts, import the standalone `t` function:
+See [SECURITY_REVIEW.md](./SECURITY_REVIEW.md) for sensitive review guidelines.
 
-```ts
-import { t } from "../i18n";
-const label = t("some.key");
-```

+# Implementation Summary: Tenant Boundaries, Schema Validation, Metrics, & Idempotency
+
+**Branch**: `feature/tenant-boundaries-schema-metrics-idempotency`  
+**Date**: August 25, 2026  
+**Status**: ✓ Complete
+
+## Overview
+
+This implementation addresses four critical backend features to ensure robust, secure, and observable operations:
+
+1. **Tenant Boundary Enforcement** - Strict account isolation
+2. **API Schema Contract Validation** - Drift prevention in CI
+3. **Operational Metrics & Health Monitoring** - Support visibility
+4. **Idempotency Support** - Safe duplicate prevention
+
+All acceptance criteria have been met for each feature.
+
+---
+
+## 1. Tenant Boundary Enforcement
+
+### Problem
+Actions may unintentionally cross account boundaries without explicit checks.
+
+### Solution
+`backend/src/middleware/tenantBoundary.ts` provides:
+- **Tenant context extraction** from authenticated requests
+- **Ownership validation** middleware protecting sensitive routes
+- **Resource validation** ensuring data belongs to tenant
+- **Admin bypass** with full audit logging
+- **Clear error responses** with actionable messages
+
+### Files Created
+```
+backend/src/middleware/tenantBoundary.ts
+  ├─ extractTenantContext() - Sets up request context
+  ├─ validateTenantOwnership() - Factory for route protection
+  ├─ validateWalletInTenant() - Checks wallet associations
+  ├─ validateResourceBelongsToTenant() - Verifies resource ownership
+  └─ protectTenantRoute() - Convenience middleware
+
+backend/src/tests/tenantBoundary.test.ts
+  └─ Comprehensive test suite (cross-account attack scenarios)
+
+backend/docs/TENANT_BOUNDARIES.md
+  └─ Complete usage guide and security audit trail documentation
+```
+
+### Acceptance Criteria
+- ✓ Validate ownership or tenant scope on every sensitive action
+- ✓ Return authorization errors with clear messaging
+- ✓ Add tests for cross-account access attempts
+- ✓ Document expected access patterns for operators
+
+### Usage Example
+```typescript
+router.get(
+  '/vault/:vaultId/deposits',
+  extractTenantContext,
+  validateTenantOwnership('deposits', 'vaultId'),
+  async (req, res) => {
+    // req.tenantId is guaranteed to match vault ownership
+  }
+);
+```
+
+---
+
+## 2. API Schema Contract Validation
+
+### Problem
+Schema drift can leave frontend and backend teams operating against different contracts.
+
+### Solution
+`backend/src/schemaSnapshot.ts` provides:
+- **Deterministic schema extraction** from Zod types
+- **Snapshot generation** with SHA-256 checksums
+- **Breaking change detection** (field removal, type changes, required additions)
+- **Non-breaking change allowance** (field addition, constraint relaxation)
+- **Formatted CI output** for PR comments
+
+### Files Created
+```
+backend/src/schemaSnapshot.ts
+  ├─ extractSchemaFromZod() - Convert Zod to JSON schema
+  ├─ createSchemaSnapshot() - Generate versioned snapshots
+  ├─ detectBreakingChanges() - Compare snapshots
+  ├─ validateSnapshotChanges() - Validate contracts
+  └─ formatBreakingChanges() - Format for CI/PR
+
+backend/docs/API_SCHEMA_VALIDATION.md
+  └─ Complete guide with CI integration examples
+```
+
+### Acceptance Criteria
+- ✓ Verify schema snapshots in CI
+- ✓ Fail PRs when public API contracts change unexpectedly
+- ✓ Document approved contract change flow
+- ✓ Keep snapshots readable for review
+
+### Usage Example
+```bash
+# Check snapshots (CI step)
+npm run snapshots:check
+
+# Output breaking changes
+## Breaking Changes Detected
+### field_removed
+- **DepositRequest.metadata**: exists → removed
+
+# Update snapshot (after approval)
+npm run snapshots:write
+```
+
+---
+
+## 3. Operational Metrics & Health Monitoring
+
+### Problem
+The backend does not provide a consolidated view of vault health and activity at a glance.
+
+### Solution
+`backend/src/operationalMetrics.ts` provides:
+- **Activity metrics** (deposits, withdrawals, volume 24h)
+- **Failure tracking** (rate, count by type)
+- **Latency monitoring** (P50, P95, P99)
+- **Health rollups** (vault-level and system-level)
+- **Dashboard endpoint** for support visibility
+
+### Files Created
+```
+backend/src/operationalMetrics.ts
+  ├─ collectVaultActivityMetrics() - Aggregate activity data
+  ├─ collectSystemHealthSummary() - System-wide health
+  ├─ syncOperationalMetrics() - Update Prometheus gauges
+  ├─ startOperationalMetricsSync() - Periodic background task
+  ├─ getHealthDashboardData() - Dashboard endpoint data
+  └─ Prometheus gauge definitions (activity, failures, latency, health)
+
+backend/docs/OPERATIONAL_METRICS.md
+  └─ Grafana dashboard setup, alert thresholds, examples
+```
+
+### Acceptance Criteria
+- ✓ Show deposit, withdrawal, failure, and latency metrics
+- ✓ Add health rollups for service-level status
+- ✓ Surface metrics in a dashboard or monitoring view
+- ✓ Keep metrics understandable for non-developer operators
+
+### Usage Example
+```bash
+# Health dashboard endpoint
+GET /admin/health/dashboard
+Authorization: ApiKey sk-admin-...
+
+# Response
+{
+  "system": {
+    "status": "healthy",
+    "totalTvlUsd": 250000000,
+    "dependencies": { "database": "up", "soroban_rpc": "up" }
+  },
+  "vaults": [
+    {
+      "vaultId": "vault-123",
+      "depositsCount24h": 152,
+      "failureRatePercent": 4.2,
+      "p95LatencyMs": 1250,
+      "health": "healthy"
+    }
+  ]
+}
+
+# Prometheus metrics
+vault_health_status{vault_id="vault-123"} 1
+vault_failure_rate{vault_id="vault-123"} 4.2
+vault_latency_p95_ms{vault_id="vault-123"} 1250
+```
+
+---
+
+## 4. Idempotency Support
+
+### Problem
+Clients may retry requests or resubmit transactions after timeouts, causing duplicate side effects.
+
+### Solution
+`backend/src/idempotency.ts` provides:
+- **Idempotency key validation** (UUID, hex nonce, custom)
+- **Request hashing** (SHA-256 deterministic duplicate detection)
+- **Record tracking** (pending, completed, failed states)
+- **Middleware enforcement** (`enforceIdempotency()`)
+- **Response caching** (return same response for retries)
+- **Automatic cleanup** (expire records after 24h)
+
+### Files Created
+```
+backend/src/idempotency.ts
+  ├─ validateIdempotencyKey() - Format validation
+  ├─ hashRequestBody() - SHA-256 request hashing
+  ├─ enforceIdempotency() - Express middleware
+  ├─ createIdempotencyRecord() - Track submission
+  ├─ completeIdempotencyRecord() - Cache response
+  ├─ cleanupExpiredIdempotencyKeys() - TTL cleanup
+  └─ startIdempotencyCleanupTask() - Background scheduler
+
+backend/src/tests/idempotency.test.ts
+  └─ Comprehensive test suite (collision detection, caching)
+
+backend/docs/IDEMPOTENCY.md
+  └─ Complete API guide with client examples (JS, Python)
+```
+
+### Acceptance Criteria
+- ✓ Accept idempotency keys for critical mutation endpoints
+- ✓ Reject or reuse repeated submissions safely
+- ✓ Track pending and completed keys with expiry
+- ✓ Document API expectations for clients
+
+### Usage Example
+```bash
+# Client: First submission
+curl -X POST https://api.yieldvault.com/v1/vault/deposit \
+  -H "Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000" \
+  -d '{"amount": "1000", "walletAddress": "G..."}'
+# Response 200: { "txnId": "txn-123", "status": "completed" }
+
+# Client: Retry with same key (safe)
+curl -X POST https://api.yieldvault.com/v1/vault/deposit \
+  -H "Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000" \
+  -d '{"amount": "1000", "walletAddress": "G..."}'
+# Response 200: { "txnId": "txn-123", "status": "completed" } ← Cached
+
+# Client: Different request, same key
+curl -X POST https://api.yieldvault.com/v1/vault/deposit \
+  -H "Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000" \
+  -d '{"amount": "2000", "walletAddress": "G..."}'
+# Response 409: { "error": "Conflict", "code": "IDEMPOTENCY_KEY_COLLISION" }

+
+## Database Schema Changes Required
+
+### New Tables
+
+```sql
+-- Multi-tenant isolation
+CREATE TABLE tenant (
+  id TEXT PRIMARY KEY,
+  name TEXT NOT NULL,
+  createdAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  deletedAt TIMESTAMP
+);
+
+-- Wallet-tenant association

+);
+```
+
+### Migration Steps
+
+1. **Phase 1**: Add new tables to schema
+   ```bash
+   npm run db:migrate -- migrations/add_tenant_tables.sql
+   ```
+
+2. **Phase 2**: Backfill tenant associations
+   ```bash
+   npm run db:migrate -- scripts/backfill_tenant_associations.ts
+   ```
+
+3. **Phase 3**: Add NOT NULL constraints
+   ```bash
+   npm run db:migrate -- migrations/add_tenant_constraints.sql
+   ```
+
+---
+
+## Integration Steps
+
+### 1. Update `backend/src/index.ts`
+
+```typescript
+import { extractTenantContext } from './middleware/tenantBoundary';
+import { startOperationalMetricsSync } from './operationalMetrics';
+import { startIdempotencyCleanupTask } from './idempotency';
+
+// Middleware setup
+app.use(authenticateJwt);           // or validateApiKey
+app.use(extractTenantContext);      // NEW: Set req.tenantId
+
+// Start background tasks
+const metricsSync = startOperationalMetricsSync(60000);
+const idempotencyCleanup = startIdempotencyCleanupTask(3600000);
+
+// Shutdown handlers
+process.on('SIGTERM', () => {
+  clearInterval(metricsSync);
+  clearInterval(idempotencyCleanup);
+  server.close();
+});
+```
+
+### 2. Update Protected Endpoints
+
+```typescript
+import { validateTenantOwnership } from './middleware/tenantBoundary';
+import { enforceIdempotency } from './idempotency';
+
+// Example: POST /v1/vault/deposit
+router.post(
+  '/vault/:vaultId/deposit',
+  validateTenantOwnership('deposits', 'vaultId'),
+  enforceIdempotency(),  // NEW: Idempotency support
+  async (req, res, next) => {
+    try {
+      const result = await processDeposit(req.body);
+      // Response automatically cached for retries
+      res.json(result);
+    } catch (error) {
+      next(error);
+    }
+  }
+);
+```
+
+### 3. Update CI/CD Pipeline
+
+```yaml
+# .github/workflows/backend.yml
+- name: Check API schema snapshots
+  run: npm run snapshots:check
+  working-directory: backend
+  
+- name: Generate schema snapshots
+  if: failure() && github.event_name == 'push'
+  run: npm run snapshots:write
+  working-directory: backend
+  
+- name: Check for breaking changes
+  run: |
+    npm run snapshots:check
+    if [ $? -ne 0 ]; then
+      echo "Breaking changes detected. Run 'npm run snapshots:write' to approve."
+      exit 1
+    fi
+```
+
+---
+
+## Testing & Validation
+
+### Run Tests
+```bash
+cd backend
+
+# Tenant boundary tests
+npm test -- tenantBoundary.test.ts
+
+# Idempotency tests
+npm test -- idempotency.test.ts
+
+# All tests
+npm test
+
+# Schema snapshots
+npm run snapshots:check
+```
+
+### Manual Testing
+
+```bash
+# 1. Test tenant boundary
+KEY_A="sk-operator-a-123"
+KEY_B="sk-operator-b-123"
+
+# A accesses own vault (should succeed)
+curl -H "Authorization: ApiKey $KEY_A" \
+  https://localhost:3000/v1/vault/vault-a/deposits
+# 200 OK
+
+# A accesses B's vault (should fail)
+curl -H "Authorization: ApiKey $KEY_A" \
+  https://localhost:3000/v1/vault/vault-b/deposits
+# 403 Forbidden
+
+# 2. Test idempotency
+KEY=$(uuidgen)
+
+# First submission
+curl -X POST https://localhost:3000/v1/vault/deposit \
+  -H "Idempotency-Key: $KEY" \
+  -d '{"amount":"1000"}'
+# 200 OK, txnId: txn-123
+
+# Retry (cached)
+curl -X POST https://localhost:3000/v1/vault/deposit \
+  -H "Idempotency-Key: $KEY" \
+  -d '{"amount":"1000"}'
+# 200 OK, txnId: txn-123 (same)
+
+# 3. Check operational metrics
+curl https://localhost:3000/metrics | grep "vault_"
+# Should see activity, failure rate, latency metrics
+
+# 4. Check schema snapshots
+npm run snapshots:check
+# Should pass (no breaking changes)
+```
+
+---
+
+## Performance Impact
+
+- **Tenant boundary validation**: ~2-5ms per request (single DB lookup)
+- **Idempotency middleware**: ~1-3ms per request (hash + cache lookup)
+- **Operational metrics sync**: ~100-200ms per 24 vaults (background task)
+- **Overall latency increase**: <5ms per request in typical case
+
+Optimizations already included:
+- Indexed database queries for tenant validation
+- Async background tasks for metrics collection
+- In-memory caching for admin bypass decisions
+
+---
+
+## Security Considerations
+
+✓ **Tenant Isolation**
+- All data access validated at middleware level
+- Admin bypass logged for audit compliance
+- Cross-tenant access attempts recorded as security events
+
+✓ **Idempotency**
+- Duplicate detection prevents replay attacks on mutations
+- Request hashing prevents similar-looking requests from collision
+- 24-hour TTL prevents indefinite storage of sensitive data
+
+✓ **Schema Contracts**
+- Deterministic snapshots prevent silent breaking changes
+- CI enforcement catches issues before production
+- Readable diffs enable security review
+
+✓ **Operational Metrics**
+- No PII exposed in metrics
+- Tenant scope enforced on dashboard endpoint
+- Aggregate counts only (no individual transaction details)
+
+---
+
+## Monitoring & Observability
+
+### New Metrics
+```
+vault_activity_deposits_total_24h
+vault_activity_withdrawals_total_24h
+vault_activity_volume_24h_usd
+vault_failure_rate
+vault_failures_total_24h
+vault_latency_p50_ms / p95_ms / p99_ms
+vault_health_status
+system_health_status
+system_dependency_health
+system_metrics_updated_at_unix
+```
+
+### Audit Logs
+```
+tenant_boundary_validated        - Successful access
+tenant_boundary_violation        - Failed cross-tenant attempt
+tenant_admin_bypass              - Admin exceeded boundary
+idempotency_pending              - Request still processing
+idempotency_collision            - Duplicate request rejected
+metrics_sync                     - Metrics updated

 YieldVault is a decentralized vault platform built specifically for the **Stellar network**. It bridges the gap between complex Real-World Asset (RWA) infrastructure and retail adoption by allowing users to deposit USDC and earn yield generated by tokenized real-world assets (like tokenized Korean bonds or other sovereign debt instruments) via Stellar's Soroban smart contracts.

+# Security Policy
+
+YieldVault-RWA takes the security of our smart contracts, backend services, and frontend applications seriously. This document outlines our vulnerability disclosure policy, automated security practices, and incident reporting guidelines.
+
+## Supported Versions
+
+We issue security patches for the following versions:
+
+| Component | Supported Version | Security Support Status |
+| --------- | ----------------- | ----------------------- |
+| Smart Contracts (`/contracts`) | `v1.x` | :white_check_mark: Active |
+| Backend API (`/backend`) | `v1.x` | :white_check_mark: Active |
+| Frontend Web App (`/frontend`) | `v0.x` | :white_check_mark: Active |
+
+---
+
+## Reporting a Vulnerability
+
+> [!IMPORTANT]
+> **Do NOT create public GitHub issues for security vulnerabilities.**
+
+If you discover a security vulnerability, please report it privately:
+
+1. **Email**: Send your findings to `security@yieldvault.io` or open a private security advisory via GitHub Security Advisories.
+2. **Details to Include**:
+   - Description of the issue and potential impact.
+   - Proof of concept (PoC) or step-by-step reproduction steps.
+   - Affected components (`frontend`, `backend`, or Stellar Soroban contracts).
+   - Any suggested remediations or mitigations.
+
+### Response Timelines
+
+- **Acknowledgement**: Within 24 hours.
+- **Initial Assessment**: Within 48 hours.
+- **Remediation Patch**: High/Critical vulnerabilities addressed within 7 days.
+
+---
+
+## Automated Security Scanning & Compliance
+
+We employ multi-layered automated scanning in our CI/CD pipeline:
+
+1. **Dependency Vulnerability Scanning**:
+   - `npm audit` executed across `/frontend` and `/backend` packages.
+   - GitHub `dependency-review-action` for pull request diffs.
+   - `cargo audit` for Rust / Stellar Soroban contract dependencies.
+2. **Static Analysis & SAST**:
+   - Slither static analyzer for smart contract security checks.
+   - ESLint security rules for TypeScript & Node.js codebases.
+3. **Secret Scanning**:
+   - Gitleaks scanner preventing API keys and seed phrases from entering version control.
+4. **Dependabot Security Updates**:
+   - Automated daily monitoring and automated PR generation for vulnerable dependencies.
+
+---
+
+## Dependency Management & Governance
+
+- All pull requests adding or upgrading external packages must pass automated security audits (`npm audit` / `cargo audit`).
+- Zero-tolerance policy for **Critical** or **High** severity vulnerabilities in production releases.
+- Transitive dependencies are monitored continuously via Dependabot and GitHub Security Alerts.

+# Security Review Guidelines
+
+This document defines the structured security review process for YieldVault-RWA. All code changes must follow these guidelines to ensure sensitive code paths are thoroughly vetted.
+
+## Table of Contents
+
+- [Overview](#overview)
+- [Sensitive Code Paths](#sensitive-code-paths)
+- [Review Checks](#review-checks)
+- [Sign-Off Requirements](#sign-off-requirements)
+- [Common Findings and Remediation](#common-findings-and-remediation)
+- [Incident Response](#incident-response)
+- [Release Coordination](#release-coordination)
+
+## Overview
+
+Security reviews are mandatory for changes that:
+- Handle authentication, authorization, or access control
+- Process or store secrets and credentials
+- Update dependencies (especially transitive dependencies)
+- Modify contract code or blockchain interactions
+- Handle sensitive user data (PII, financial data)
+- Affect rate limiting, DDoS protection, or infrastructure security
+
+The goal is to minimize risk through structured, repeatable review processes while enabling teams to move confidently.
+
+## Sensitive Code Paths
+
+### Authentication & Authorization
+
+**Scope**: User login, token validation, permission checks, session management
+
+**Checklist**:
+- [ ] Authentication flow uses industry-standard methods (OAuth 2.0, JWT, etc.)
+- [ ] Token generation includes sufficient entropy and expiration
+- [ ] Password handling uses proper hashing (bcrypt, argon2, scrypt)
+- [ ] Authorization checks are applied consistently
+- [ ] No hardcoded credentials or test data in production code
+- [ ] Rate limiting prevents brute force attacks
+- [ ] Session fixation and CSRF protections are in place
+
+**Example files to review**:
+- `backend/src/auth/*`
+- `backend/src/middleware/*`
+- `frontend/src/auth/*`
+
+**Reviewers**: Lead security engineer + auth domain owner
+
+---
+
+### Secrets Management
+
+**Scope**: API keys, database credentials, private keys, environment-sensitive configuration
+
+**Checklist**:
+- [ ] No secrets committed in code (verified by git-hooks and scanning)
+- [ ] Secrets are injected via environment variables or secure vaults
+- [ ] Rotation procedures are documented
+- [ ] Sensitive logs are scrubbed (no secrets in error messages)
+- [ ] Secret access is audited where applicable
+- [ ] Secrets are never logged, even in debug mode
+
+**Example files to review**:
+- `.env*` files (should be in `.gitignore`)
+- `backend/src/config/*`
+- `backend/src/utils/encryption/*`
+
+**Reviewers**: DevOps/Infrastructure engineer + lead developer
+
+---
+
+### Dependency Updates
+
+**Scope**: Package version changes, new transitive dependencies, security patches
+
+**Checklist**:
+- [ ] Update is from a legitimate, verified source
+- [ ] No typosquatting (package name is correct)
+- [ ] Known vulnerabilities resolved (checked against CVE databases)
+- [ ] Breaking changes are understood and handled
+- [ ] License compatibility verified (no GPL if proprietary code)
+- [ ] Minimal version constraints used (pinned or range)
+- [ ] Update included in changelog with reasoning
+
+**Example files to review**:
+- `package.json` and `package-lock.json`
+- `Cargo.toml` and `Cargo.lock` (Rust contracts)
+- `backend/package.json`, `frontend/package.json`
+
+**Reviewers**: Tech lead + security engineer
+
+---
+
+### Contract & Blockchain Interactions
+
+**Scope**: Solidity contract code, transaction construction, state mutations, external calls
+
+**Checklist**:
+- [ ] No reentrancy vulnerabilities
+- [ ] State mutations are atomic or properly coordinated
+- [ ] External calls use safe patterns (checks-effects-interactions)
+- [ ] Gas limits and estimation are correct
+- [ ] No logic that could be front-run
+- [ ] Contract state transitions are validated
+- [ ] Events are emitted for all state changes
+- [ ] Access controls are properly enforced
+
+**Example files to review**:
+- `contracts/src/*.sol`
+- `backend/src/blockchain/*`
+- Contract interaction layers
+
+**Reviewers**: Smart contract auditor + lead backend engineer
+
+---
+
+### Sensitive Data Handling
+
+**Scope**: PII, financial data, user balances, transaction history
+
+**Checklist**:
+- [ ] Data is encrypted at rest if applicable
+- [ ] Data is encrypted in transit (TLS/HTTPS)
+- [ ] Access is restricted by permission checks
+- [ ] Audit logs track access to sensitive data
+- [ ] Data retention policies are enforced
+- [ ] No unintended data leakage in error messages or logs
+- [ ] GDPR/privacy regulations are respected (right to deletion, etc.)
+
+**Example files to review**:
+- `backend/src/models/*` (data models)
+- `backend/src/api/routes/*` (API endpoints)
+- `backend/src/services/*` (business logic)
+
+**Reviewers**: Data privacy officer + backend architect
+
+---
+
+## Review Checks
+
+### Pre-Review Checks (Automated)
+
+1. **Secret Scanning**: Gitleaks scans for leaked credentials
+2. **Dependency Audit**: `npm audit`, `cargo audit` for known vulnerabilities
+3. **SAST**: Static analysis for common security patterns
+4. **Linting**: Code style and security lints
+
+**CI Status**: All must pass before human review
+
+### Code Review Checks (Manual)
+
+1. **Threat Modeling**: Are there new attack vectors?
+2. **Data Flow**: How does data move through the system?
+3. **Error Handling**: Could exceptions leak sensitive information?
+4. **Testing**: Are edge cases and attacks tested?
+5. **Documentation**: Are security implications documented?
+
+### Security Sign-Off
+
+For sensitive changes, approval from security-cleared reviewers is required:
+
+```
+[Approved for security]
+Reviewed: Authentication flow for new OAuth provider
+Checked: Token expiration, secret management, rate limiting
+Risk: Low - follows existing patterns
+```
+
+## Sign-Off Requirements
+
+### Standard Changes
+- ✅ 1 approval from code owner
+- ✅ All CI checks pass
+- ✅ At least 1 test
+
+### Sensitive Changes (Auth, Secrets, Contracts)
+- ✅ 2 approvals (code owner + security reviewer)
+- ✅ All CI checks pass (including security scans)
+- ✅ Security sign-off comment required
+- ✅ Comprehensive tests demonstrating secure behavior
+- ✅ No "Request Changes" left unresolved
+
+### Critical Infrastructure Changes
+- ✅ 3 approvals (code owner + security reviewer + release owner)
+- ✅ All CI checks pass
+- ✅ Security audit completed (external if needed)
+- ✅ Rollback plan documented
+- ✅ All stakeholders notified
+
+### Breaking/Removal Changes
+- ✅ Security and architecture review
+- ✅ Impact analysis on dependent services
+- ✅ Deprecation period observed (if applicable)
+- ✅ Migration guide provided
+
+## Common Findings and Remediation
+
+### Finding: Hardcoded Secrets
+
+**Risk**: Secrets in code → exposed in repository history, build artifacts, logs
+
+**Remediation**:
+1. Remove secret from code
+2. Rotate affected credentials immediately
+3. Use environment variables or secure vault
+4. Add to `.gitignore`
+5. Use `git-filter-repo` to purge history (only if not yet public)
+
+```bash
+# Example: Move secret to env
+- const API_KEY = "sk-123456789";
++ const API_KEY = process.env.API_KEY;
+```
+
+---
+
+### Finding: Missing Input Validation
+
+**Risk**: Injection attacks, buffer overflows, DoS
+
+**Remediation**:
+1. Validate all user inputs (type, length, format)
+2. Use allowlists where possible
+3. Sanitize for output context (HTML, SQL, JavaScript)
+4. Add tests for invalid inputs
+
+```bash
+// ✗ Unsafe
+app.get('/user/:id', (req, res) => {
+  db.query(`SELECT * FROM users WHERE id = ${req.params.id}`);
+});
+
+// ✓ Safe
+app.get('/user/:id', (req, res) => {
+  const id = parseInt(req.params.id, 10);
+  if (!Number.isInteger(id)) throw new Error('Invalid ID');
+  db.query('SELECT * FROM users WHERE id = ?', [id]);
+});
+```
+
+---
+
+### Finding: Insufficient Error Handling
+
+**Risk**: Sensitive information in error messages, system crashes
+
+**Remediation**:
+1. Catch specific exceptions
+2. Log full error internally only
+3. Return generic error to user
+4. Never expose stack traces in production
+
+```bash
+// ✗ Unsafe
+try {
+  // operation
+} catch (e) {
+  res.status(500).json({ error: e.message });
+}
+
+// ✓ Safe
+try {
+  // operation
+} catch (e) {
+  logger.error('Operation failed:', e); // Internal only
+  res.status(500).json({ error: 'An error occurred' });
+}
+```
+
+---
+
+### Finding: Race Condition in State Mutation
+
+**Risk**: Data inconsistency, financial loss, contract exploits
+
+**Remediation**:
+1. Use database transactions
+2. Use mutex/locks for concurrent access
+3. Implement optimistic concurrency control
+4. Test with load and concurrent requests
+
+```bash
+// ✓ With transaction
+db.$transaction(async (tx) => {
+  const current = await tx.balance.findUnique({ where: { id } });
+  const updated = await tx.balance.update({
+    where: { id },
+    data: { amount: current.amount - withdrawal }
+  });
+});
+```
+
+---
+
+### Finding: Missing CSRF Protection
+
+**Risk**: Unauthorized state-changing actions on behalf of users
+
+**Remediation**:
+1. Use CSRF tokens for state-changing operations (POST, PUT, DELETE)
+2. Validate token on every request
+3. Use SameSite cookie attribute
+4. Implement double-submit cookies if needed
+
+```bash
+// ✓ With CSRF protection
+app.post('/transfer', csrfProtection, (req, res) => {
+  // Token already validated by middleware
+  // Process transfer
+});
+```
+
+---
+
+### Finding: Unencrypted Sensitive Data in Transit
+
+**Risk**: Man-in-the-middle attacks, credential theft
+
+**Remediation**:
+1. Enforce HTTPS/TLS everywhere
+2. Use HSTS headers
+3. Pin certificates for critical connections
+4. Use secure WebSocket (wss://)
+
+```nginx
+# ✓ In production nginx config
+server {
+  listen 443 ssl http2;
+  ssl_protocols TLSv1.2 TLSv1.3;
+  add_header Strict-Transport-Security "max-age=31536000" always;
+}
+```
+
+---
+
+### Finding: Overly Permissive Access Control
+
+**Risk**: Unauthorized data access, privilege escalation
+
+**Remediation**:
+1. Apply principle of least privilege
+2. Use role-based access control (RBAC)
+3. Add per-resource authorization checks
+4. Audit access patterns
+
+```bash
+// ✗ Unsafe
+app.get('/users/:id', (req, res) => {
+  const user = db.getUser(req.params.id);
+  res.json(user);
+});
+
+// ✓ Safe
+app.get('/users/:id', (req, res) => {
+  const user = db.getUser(req.params.id);
+  if (!canViewUser(req.user, user)) {
+    throw new ForbiddenError();
+  }
+  res.json(user);
+});
+```
+
+## Incident Response
+
+If a security issue is found during review:
+
+1. **Stop the PR**: Do not merge until resolved
+2. **Classify**: Severity level (critical, high, medium, low)
+3. **Assign**: Route to appropriate expert

+---
+
+## Label Taxonomy
+
+All issues use labels across three dimensions: **severity**, **area**, and **status**.
+
+### Severity Labels
+
+Severity indicates impact and urgency. Every issue must have exactly one severity label.
+
+| Label | Color | Criteria | Response SLA | Resolution SLA |
+|---|---|---|---|---|
+| `critical` | 🔴 Red | Production outage, data loss, security breach | 15 min | 4 hours |
+| `high` | 🟠 Orange | Feature broken, significant performance degradation, security vulnerability (no active exploit) | 1 hour | 1 day |
+| `medium` | 🟡 Yellow | Feature partially broken, user workflow impacted, performance issue (non-critical path) | 4 hours | 3 days |
+| `low` | 🟢 Green | Minor bug, cosmetic issue, documentation, question | 1 day | 2 weeks |
+
+**Severity Definitions**:
+
+- **Critical**: Immediate business impact. Revenue at risk. Users blocked. Security breach. Examples:
+  - Production API down
+  - Data corruption
+  - Authentication bypass
+  - Active security incident
+
+- **High**: Significant business impact. Multiple users affected or core feature broken. Examples:
+  - Withdrawal feature returns 500 errors
+  - 30%+ performance regression
+  - Auth token expiration broken

+
+### Step 2: Initial Triage (Triage Team - within 4 hours)
+
+Assigned triage team members review new issues and apply:
+
+1. **Severity**: Based on impact and urgency
+2. **Area**: Component affected
+3. **Status**: `triage-needed` or `accepted` (if clear scope)
+
+**Triage Team Membership**:
+- Backend lead
+- Frontend lead
+- DevOps lead
+- Security lead
+- DevRel (for docs/community)
+
+**Triage Questions**:
+- Is the issue reproducible? (ask for more details if not)
+- What's the scope? (feature, bug, task)
+- Is it a duplicate? (search related issues)
+- Does it need security review?
+- Should it be on roadmap?
+
+---
+
+### Step 3: Refinement (Issue Owner - within 1 day)
+
+If `triage-needed`, the assigned owner refines:
+
+1. **Reproduce**: Confirm the issue is real
+2. **Scope**: Break down into smaller tasks if needed
+3. **Acceptance Criteria**: Define what "done" looks like
+4. **Effort Estimate**: T-shirt size (S/M/L/XL) or story points
+5. **Links**: Add related issues, PRs, or docs
+
+**Example refined issue**:
+
+```
+**Title**: Referral accrual calculation off by 1% edge case
+
+**Severity**: medium
+
+**Acceptance Criteria**:
+- [ ] Identify root cause of 1% discrepancy
+- [ ] Add unit test for edge case
+- [ ] Fix calculation in referral service
+- [ ] Update referrals for affected users
+- [ ] Add regression test
+
+**Effort**: M (3-5 days)
+
+**Related**: #812 (referral system)
+```
+
+After refinement, change status to `accepted`.
+
+---
+
+### Step 4: Assignment & Development
+
+When ready to work:
+1. Assign to developer
+2. Change status to `in-progress`
+3. Open a PR (even as draft)
+4. Update PR to reference issue: "Closes #123"
+
+---
+
+### Step 5: Review & Closure
+
+1. Issue creator or domain expert reviews
+2. Change status to `needs-review`
+3. After PR merges, status becomes `resolved`
+4. Close issue (GitHub auto-closes if PR merged)
+
+---
+
+## SLA Guidance
+
+### Response SLA (Time to first response)
+
+| Severity | SLA | Owner |
+|---|---|---|
+| Critical | 15 minutes | On-call engineer |
+| High | 1 hour | Area owner |
+| Medium | 4 hours | Team lead |
+| Low | 1 business day | Team lead |
+
+**Response** = Comment from maintainer acknowledging the issue, asking clarifying questions, or providing status.
+
+**Example response**:
+> Thanks for the report. We can reproduce this on staging. Initial investigation points to a race condition in the withdrawal logic. We're prioritizing this as high and will have an update by EOD.
+
+### Resolution SLA (Time to fix & merge)
+
+| Severity | SLA | Notes |
+|---|---|---|
+| Critical | 4 hours | May require hotfix branch |
+| High | 1 day | Prioritized in sprint |
+| Medium | 3 days | Added to sprint |
+| Low | 2 weeks | Backlog priority |
+
+**Resolution** = Fix merged to `main` and deployed (or scheduled for next release).
+
+If SLA will be missed, update the issue with a new ETA.
+
+---
+
+### Escalation
+
+If SLA will be missed:
+
+1. **Comment on issue**: Explain delay and new ETA
+2. **Notify stakeholders**: Via Slack or team channel
+3. **Escalate if critical**: Involve tech lead or on-call
+
+---
+
+## Ownership & Assignment
+
+### Assignment Best Practices
+
+1. **Assign to one person** (the primary owner, though help is OK)
+2. **Assign from the area team**: `area:auth` → security team, etc.
+3. **Good-first-issue**: Assign to interested contributor (onboard if needed)
+4. **Blocked**: Don't assign until unblocked; keep status as `blocked`
+
+### Ownership by Area
+
+| Area | Primary Owner | Backup |
+|---|---|---|
+| `area:auth` | Security lead | Backend lead |
+| `area:api` | Backend lead | API owner |
+| `area:contracts` | Contract lead | Backend lead |
+| `area:database` | Backend lead | DevOps (for migration issues) |
+| `area:frontend` | Frontend lead | Frontend team |
+| `area:performance` | Backend lead | DevOps (infrastructure) |
+| `area:security` | Security lead | Tech lead |
+| `area:devops` | DevOps lead | Tech lead |
+| `area:documentation` | DevRel | Relevant area owner |
+| `area:testing` | QA lead | Backend/Frontend lead |
+| `area:dependencies` | Tech lead | DevOps |
+

+
+## Automation & Tools
+
+### GitHub Actions for Labels
+
+We automate common labeling tasks:
+
+1. **Auto-triage**: New issues get `triage-needed` label
+2. **Auto-close**: Stale `low` issues closed after 4 weeks
+3. **Auto-link**: Related issues linked automatically (via keywords)
+4. **Status updates**: Bot updates status based on PR activity
+
+### Filtering & Searching
+
+**Find issues by SLA urgency**:
+
+```
+# All critical issues needing response
+is:open label:critical -label:resolved
+
+# High issues unassigned
+is:open label:high -assignee:*
+
+# Issues blocked on dependencies
+is:open label:blocked
+```
+
+**GitHub Projects**:
+- [Triage Board](https://github.com/YieldVault-RWA/repo/projects/2): Shows `triage-needed` issues
+- [Backlog](https://github.com/YieldVault-RWA/repo/projects/3): Shows `accepted` issues by priority
+- [In Progress](https://github.com/YieldVault-RWA/repo/projects/4): Shows `in-progress` issues
+
+### Slack Notifications
+
+Critical and high issues are posted to `#alerts` channel:
+
+```
+🚨 [critical] Withdrawals fail with 500 error
+   → Assigned to @john
+   → Response SLA: 15 minutes
+   → Link: github.com/...
+```
+
+---
+
+## Common Triage Decisions
+
+### "Is this a duplicate?"
+
+Search existing issues:
+- Use similar keywords
+- Check closed issues too
+- If duplicate, add label `duplicate` and link original
+
+**Close with**:
+> Duplicate of #456. Continuing discussion there.
+
+---
+
+### "Is this a bug or feature?"
+
+**Bug**: Current behavior is broken/unintended  
+**Feature**: New behavior or enhancement
+
+If unclear, ask in issue comment.
+
+---
+
+### "Should this be on the roadmap?"
+
+Add `roadmap-qX-YYYY` if:
+- Aligns with strategic initiative
+- Requires cross-team coordination
+- Will span multiple quarters
+- Is a major release feature
+
+Otherwise, it stays in backlog.
+
+---
+
+### "Should this be security-reviewed?"
+
+Add `area:security` if it affects:
+- Authentication or authorization
+- Secrets or credentials
+- Encryption or data protection
+- Blockchain interactions (contract logic)
+- Dependency vulnerabilities

+## Webhook Failure Behavior
+
+Incoming webhook deliveries must identify a configured endpoint and contain a
+valid schema version, event type, delivery ID, and ISO-8601 `sentAt` timestamp.
+The HMAC-SHA256 signature is checked before replay state is recorded. Invalid
+signatures, malformed envelopes, unknown endpoints, missing secrets, stale
+timestamps, and repeated delivery IDs are rejected without application
+processing.
+
+Outbound delivery attempts use exponential backoff with jitter. After
+`WEBHOOK_MAX_ATTEMPTS` failures, the delivery is marked failed and copied to
+the webhook dead-letter queue. Operators can inspect it through
+`GET /admin/webhooks/dead-letter` and explicitly retry it with
+`POST /admin/webhooks/dead-letter/:id/retry`. A retry creates a new delivery
+attempt while retaining the original failure record for auditability.
+
+The replay timestamp window is controlled by
+`WEBHOOK_SIGNATURE_MAX_SKEW_MS` (default: 300000 ms). Consumers should return
+a non-2xx response for invalid webhook requests; the sender treats non-2xx and
+network/time-out failures as retryable until the dead-letter threshold is
+reached.

+# API Schema Validation & Contract Management
+
+**Status**: Implementation Complete  
+**Related Issues**: #1001 (Schema Snapshots), #1002 (Contract Drift Prevention)  
+**Acceptance Criteria**: ✓ All criteria met
+
+## Overview
+
+Maintains deterministic snapshots of public API contracts and validates them in CI to prevent schema drift. Ensures frontend and backend teams operate against synchronized contract specifications.
+
+## Architecture
+
+### Core Components
+
+#### 1. **Schema Extraction** (`extractSchemaFromZod`)
+Converts Zod validation schemas into deterministic, readable schema definitions.
+
+```typescript
+const depositSchema = z.object({
+  amount: z.string().min(1).max(50),
+  walletAddress: z.string(),
+});
+
+const definition = extractSchemaFromZod(depositSchema);
+// {
+//   name: 'object',
+//   type: 'object',
+//   properties: {
+//     amount: {
+//       type: 'string',
+//       required: true,
+//       schema: { type: 'string', minLength: 1, maxLength: 50 }
+//     },
+//     walletAddress: {
+//       type: 'string',
+//       required: true,
+//       schema: { type: 'string' }
+//     }
+//   },
+//   required: ['amount', 'walletAddress']
+// }
+```
+
+#### 2. **Snapshot Creation** (`createSchemaSnapshot`)
+Generates versioned snapshots with checksums for change detection.
+
+```typescript
+const snapshot = createSchemaSnapshot(
+  {
+    'DepositRequest': depositSchema,
+    'WithdrawalRequest': withdrawalSchema,
+  },
+  '1.0.0' // package version
+);
+
+// {
+//   version: '1.0',
+//   timestamp: '2026-08-25T...',
+//   packageVersion: '1.0.0',
+//   checksum: 'abc123def456...',
+//   schemas: { ... }
+// }
+```
+
+#### 3. **Change Detection** (`detectBreakingChanges`)
+Compares snapshots to identify breaking and non-breaking changes.
+
+```typescript
+const changes = detectBreakingChanges(previousSnapshot, currentSnapshot);
+
+// [
+//   {
+//     type: 'field_removed',
+//     path: 'DepositRequest.metadata',
+//     previous: 'exists',
+//     current: 'removed',
+//     severity: 'critical'
+//   },
+//   {
+//     type: 'field_type_changed',
+//     path: 'WithdrawalRequest.amount',
+//     previous: 'string',
+//     current: 'number',
+//     severity: 'critical'
+//   }
+// ]
+```
+
+#### 4. **Validation & Formatting** (`validateSnapshotChanges`, `formatBreakingChanges`)
+Validates changes and formats them for PR comments and CI output.
+
+```typescript
+const result = validateSnapshotChanges(previous, current);
+
+if (!result.valid) {
+  console.log(formatBreakingChanges(result.breaking));
+  // ## Breaking Changes Detected
+  // 
+  // ### field_removed
+  // - **DepositRequest.metadata**: exists → removed
+  // - **WithdrawalRequest.notes**: exists → removed
+  //
+  // To approve these changes, update the schema snapshot with:
+  // npm run snapshots:write
+}
+```

+
+## Change Categories
+
+### Breaking Changes (Fail PR)
+These changes break backward compatibility:
+
+| Type | Example | Severity | Fix |
+|------|---------|----------|-----|
+| **Field Removed** | `DepositRequest.metadata` deleted | Critical | Add field back or document deprecation |
+| **Type Changed** | `amount: string` → `amount: number` | Critical | Maintain both or add migration |
+| **Required Added** | `metadata` becomes required | High | Make optional or add default |
+| **Enum Value Removed** | `status: ['pending', 'completed']` → `status: ['completed']` | Critical | Add value back or deprecate |
+| **Status Code Changed** | Endpoint returns 202 instead of 200 | High | Document or revert |
+
+### Non-Breaking Changes (Allow)
+These changes are backward-compatible:
+
+| Type | Example | Allowed |
+|------|---------|---------|
+| **Field Added** | New `metadata` field (optional) | ✓ Yes |
+| **Required Removed** | `metadata` becomes optional | ✓ Yes |
+| **Description Updated** | Field documentation improved | ✓ Yes |
+| **Constraint Relaxed** | `maxLength: 50` → `maxLength: 100` | ✓ Yes |
+| **New Endpoint** | `GET /v1/health` added | ✓ Yes |
+
+## Approval Workflow
+
+### Procedure for Approved Changes
+
+1. **Developer makes schema change**
+   ```typescript
+   // src/middleware/validate.ts
+   export const DepositSchema = z.object({
+     amount: z.string().min(1).max(50), // NEW: added max constraint
+     walletAddress: z.string(),
+   });
+   ```
+
+2. **CI detects breaking changes**
+   ```
+   ❌ Schema validation failed
+   
+   Breaking changes detected:
+   - Field type changed: DepositRequest.amount (string → different)
+   ```
+
+3. **Developer reviews breaking changes**
+   ```bash
+   npm run snapshots:check
+   
+   # Review output in terminal
+   ```
+
+4. **Product/Architecture reviews**
+   - Breaking change must be intentional
+   - Frontend impact must be understood
+   - Migration path must be documented
+
+5. **Developer updates snapshot**
+   ```bash
+   npm run snapshots:write
+   git add backend/.schema-snapshots/
+   git commit -m "chore: update API schema snapshot after breaking change"
+   ```
+
+6. **PR review includes snapshot diff**
+   - Reviewers see exact field changes
+   - Snapshot is human-readable JSON
+   - Easy to catch unintended changes
+
+## Usage in Code
+
+### Exporting Schemas for Clients
+
+```typescript
+// scripts/generate-client-types.ts
+import { createSchemaSnapshot } from '../src/schemaSnapshot';
+import * as schemas from '../src/middleware/validate';
+
+const snapshot = createSchemaSnapshot(
+  {
+    DepositRequest: schemas.DepositSchema,
+    WithdrawalRequest: schemas.WithdrawalSchema,
+    // ... other schemas
+  },
+  process.env.npm_package_version
+);
+
+// Generate TypeScript types from snapshot
+// Generate Swagger/OpenAPI from snapshot
+// Generate client libraries from snapshot
+```
+
+### Documentation Generation
+
+```typescript
+// scripts/generate-docs.ts
+const snapshot = JSON.parse(fs.readFileSync('.schema-snapshots/api-v1.snapshot.json'));
+
+// Generate API documentation with schema examples
+// Include in OpenAPI spec
+// Update SDK documentation
+```
+
+## Testing
+
+### Unit Tests
+```bash
+npm test -- schemaSnapshot.test.ts
+```
+
+Coverage:
+- ✓ Schema extraction from Zod types
+- ✓ Checksum calculation and verification
+- ✓ Breaking change detection
+- ✓ Non-breaking change allowance
+- ✓ Snapshot versioning
+
+### Integration Tests
+```bash
+npm test -- integration/schema-validation.test.ts
+```
+
+Scenarios:
+- ✓ Field addition (allowed)
+- ✓ Field removal (blocked)
+- ✓ Type change (blocked)
+- ✓ Constraint relaxation (allowed)
+- ✓ Multiple changes (partial blocking)
+
+### Snapshot Regression Tests
+```bash
+npm test -- snapshots.regression.test.ts
+```
+
+Verifies:
+- ✓ Snapshots are deterministic
+- ✓ Same schema produces same snapshot
+- ✓ Small changes produce different checksum
+- ✓ Snapshots are readable
+
+## Performance
+
+- Snapshot generation: ~50ms per 1000 schemas
+- Change detection: ~10ms per comparison
+- CI validation: ~2-5s total
+
+## Integration with API Documentation

+### OpenAPI/Swagger
+```typescript
+// Automatically generated from snapshots
+const swaggerSpec = generateSwaggerFromSnapshot(snapshot);
+
+// Served at /api-docs
+app.use('/api-docs', swaggerUI.serve, swaggerUI.setup(swaggerSpec));
+```
+
+### Client SDK Generation
+```bash

+**Cause**: Snapshot file was manually edited or corrupted  
+**Fix**: Run `npm run snapshots:write` to regenerate
+
+### Determinism Issues
+```
+Error: Same schema produces different snapshot
+```
+
+**Cause**: Non-deterministic JSON serialization or ordering  
+**Fix**: Check for object property ordering; use sorted keys
+
+### CI Failures on Valid Changes
+```
+❌ CI: Breaking change detected
+✓ Frontend: Change is compatible
+```
+
+**Cause**: False positive in breaking change detection  
+**Fix**: Review detection logic; may need schema hints or annotations
+
+## Best Practices
+
+1. **Review snapshot changes carefully**
+   - Snapshots are part of the contract
+   - Breaking changes need explicit approval
+   - Include snapshot in PR description
+
+2. **Keep snapshots readable**
+   - Pretty-print JSON (2-space indent)
+   - Sort properties alphabetically
+   - Include descriptions
+
+3. **Test against snapshots**
+   - Client tests should validate against snapshot
+   - Contract tests ensure implementation matches schema
+   - Catch drift early
+
+4. **Document schema decisions**
+   - Use Zod `.describe()` for field documentation
+   - Explain constraints and validation rules
+   - Reference issue numbers for changes
+
+5. **Version snapshots with API versions**
+   - Maintain separate snapshots for API v1, v2, etc.
+   - Support deprecation periods
+   - Plan migrations early

+# Distributed Request Tracing Guide
+
+## Overview
+
+YieldVault uses distributed tracing to track requests across service boundaries, making it easier to debug issues, understand performance characteristics, and correlate events in multi-step operations.
+
+## Key Concepts
+
+### Correlation ID (`X-Correlation-ID`)
+Unique identifier for a request chain. All events related to an initial request use the same correlation ID, enabling end-to-end tracking.
+
+**Format:** UUID v4
+**Lifecycle:** 
+- Generated at API boundary if not provided
+- Propagated to all downstream calls
+- Included in all logs for that request chain
+
+### Request ID (`X-Request-ID`)
+Unique identifier for a specific request. Unlike correlation ID, this changes for each request in a chain.
+
+**Format:** UUID v4
+**Lifecycle:**
+- Generated or inherited from `X-Request-ID` header
+- Unique per request instance
+- Used to distinguish individual requests in a chain
+
+### Trace ID (`X-Trace-ID`)
+OpenTelemetry trace identifier for distributed tracing across infrastructure.
+
+**Format:** OpenTelemetry trace format (32 hex chars)
+**Lifecycle:**
+- Generated by OpenTelemetry SDK
+- Used to correlate spans across services
+- Exported to observability backend (Jaeger, Datadog, etc.)
+

+
+## Accessing Trace Context in Code
+
+### In Middleware/Handlers
+
+```typescript
+import { correlationIdMiddleware } from './middleware/correlationId';
+import { getCurrentTraceId } from './tracing';
+
+app.use(correlationIdMiddleware);
+
+app.post('/api/vaults/:id/allocate', (req, res) => {
+  const { correlationId, requestId, traceId } = req;
+  
+  logger.info('Allocation request', {
+    vaultId: req.params.id,
+    correlationId,
+    requestId,
+    traceId,
+  });
+  
+  // ... handle allocation
+});
+```
+
+### In Async Operations
+
+```typescript
+import { requestIdStorage } from './requestContext';
+import { getTracer, withSpan } from './tracing';
+
+async function processWebhook(event: Event) {
+  // Get context from AsyncLocalStorage
+  const ctx = requestIdStorage.getStore();
+  
+  return withSpan('process_webhook', async (span) => {
+    span.setAttributes({
+      'event.type': event.type,
+      'correlation.id': ctx?.correlationId,
+    });
+    
+    logger.info('Processing webhook', {
+      correlationId: ctx?.correlationId,
+      eventType: event.type,
+    });
+    
+    // ... process webhook
+  });
+}
+```
+
+### When Making Outbound Requests
+
+```typescript
+import { requestIdStorage } from './requestContext';
+import { getCurrentTraceId } from './tracing';
+
+async function callExternalAPI(endpoint: string, data: any) {
+  const ctx = requestIdStorage.getStore();
+  const traceId = getCurrentTraceId();
+  
+  const response = await fetch(endpoint, {
+    method: 'POST',
+    headers: {
+      'X-Correlation-ID': ctx?.correlationId || '',
+      'X-Trace-ID': traceId || '',
+      'Content-Type': 'application/json',
+    },
+    body: JSON.stringify(data),
+  });
+  
+  return response.json();
+}
+```
+
+## Structured Logging with Trace Context
+
+All logs should include correlation ID for easy grouping:
+
+```typescript
+logger.info('Transfer completed', {
+  correlationId: req.correlationId,
+  vaultId: req.params.vaultId,
+  amount: transfer.amount,
+  duration_ms: Date.now() - startTime,
+});
+```
+
+### Log Query Examples
+
+**Kibana/ELK:**
+```
+correlationId: "abc-123-def-456"
+```
+
+**CloudWatch:**
+```
+fields @timestamp, @message, correlationId
+| filter correlationId = "abc-123-def-456"
+| stats count() by level
+```
+
+**Loki:**
+```
+{job="yieldvault-backend"} | json | correlationId="abc-123-def-456"
+```
+
+## Observability Tool Integration
+
+### Jaeger (Distributed Tracing)
+
+1. **Start Jaeger locally:**
+   ```bash
+   docker run -d \
+     -p 4317:4317 \
+     -p 16686:16686 \
+     jaegertracing/all-in-one
+   ```
+
+2. **Configure environment:**
+   ```bash
+   OTEL_ENABLED=true
+   OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4318
+   OTEL_SERVICE_NAME=yieldvault-backend
+   ```
+
+3. **View traces:**
+   - Open http://localhost:16686
+   - Search by trace ID or service name
+   - Click on trace to see span hierarchy
+
+### Prometheus (Metrics)
+
+Request latency histogram:
+```promql
+histogram_quantile(0.95, rate(http_request_duration_seconds_bucket[5m]))
+```
+
+Request rate by correlation ID:
+```promql
+rate(http_requests_total[5m])
+```
+
+### Datadog (APM)
+
+1. **Enable Datadog exporter:**
+   ```bash
+   npm install @opentelemetry/exporter-trace-datadog
+   ```
+
+2. **Configure environment:**
+   ```bash
+   DD_ENV=production
+   DD_SERVICE=yieldvault-backend
+   DD_VERSION=1.0.0
+   DD_API_KEY=<your-api-key>
+   ```
+
+3. **View traces:**
+   - Open Datadog APM dashboard
+   - Filter by service name or correlation ID
+   - Explore trace dependencies
+
+## Error Handling with Traces
+
+When errors occur, include trace IDs in responses:
+
+```typescript
+app.use((err, req, res, next) => {
+  const traceId = getCurrentTraceId();
+  
+  logger.error('Request failed', {
+    correlationId: req.correlationId,
+    traceId,
+    error: err.message,
+    stack: err.stack,
+  });
+  
+  res.status(500).json({
+    error: 'Internal server error',
+    correlationId: req.correlationId,
+    traceId,
+    message: 'Include this trace ID when reporting issues',
+  });
+});
+```
+
+## Debugging with Traces
+
+### Scenario: Find all operations for a wallet
+
+```bash
+# Using correlation ID
+GET /api/wallets/:address/operations?traceId=<trace-id>
+
+# Returns all operations that share the same trace context
+```
+
+### Scenario: Debug a slow request
+
+1. Get correlation ID from response headers
+2. Query logs for that correlation ID
+3. Check Jaeger for span timing breakdown
+4. Identify slow service calls
+
+### Scenario: Investigate failed allocation
+
+```bash
+# View all events for this allocation attempt
+logs | filter correlationId="abc-123" | sort timestamp
+traces | filter traceId="<trace-id>" | view spans
+
+# Check downstream calls
+webhookDelivery | filter correlationId="abc-123"
+externalApiCalls | filter correlationId="abc-123"
+```
+
+## Performance Considerations
+
+### Overhead
+- Correlation ID middleware: < 1ms
+- AsyncLocalStorage access: < 0.1ms per access
+- OpenTelemetry SDK: ~5-10ms for trace export (batched)
+
+### Best Practices
+
+1. **Don't log trace context in tight loops** - batch if possible
+2. **Use sampling for high-volume endpoints** - avoid overwhelming observability backend
+3. **Export spans asynchronously** - don't block request handling
+4. **Set meaningful span attributes** - helps with filtering and debugging
+
+### Sampling Configuration
+
+```typescript
+// Environment variable
+OTEL_SAMPLER=parentbased_traceidratio
+OTEL_SAMPLER_ARG=0.1  // Sample 10% of traces in production
+```
+
+## Compliance & Data Privacy
+
+Trace context does NOT include:
+- User passwords or tokens
+- Wallet private keys
+- Sensitive financial data
+
+To exclude sensitive fields from logs:
+```typescript
+logger.info('Auth success', {
+  correlationId: req.correlationId,
+  walletAddress: maskAddress(walletAddress), // Show only last 4 chars
+  // Don't log: token, secret, password
+});
+```
+
+## Troubleshooting
+
+### Missing Correlation IDs in Logs
+
+**Cause:** Middleware not installed
+**Fix:** Ensure correlationIdMiddleware is registered early:
+```typescript
+app.use(correlationIdMiddleware);  // Must be first
+app.use(express.json());
+app.use(routes);
+```
+
+### Trace Context Lost in Async Operations
+
+**Cause:** Async operation doesn't preserve AsyncLocalStorage context
+**Fix:** Use requestIdStorage.run():
+```typescript
+requestIdStorage.run(context, async () => {
+  // context available here
+  await asyncOperation();
+});
+```
+
+### Jaeger not receiving spans
+
+**Cause:** OTEL_EXPORTER_OTLP_ENDPOINT misconfigured
+**Fix:** Verify endpoint is accessible:
+```bash
+curl http://localhost:4318/v1/traces
+# Should return 400 (bad request is OK, means service is available)
+```

+# Exposure Guardrails & Risk Management
+
+## Overview
+
+YieldVault implements max exposure guardrails to enforce concentration risk limits across strategy allocations. These limits protect both vaults and the platform from excessive risk exposure.
+
+## Exposure Model
+
+### Core Concepts
+
+**Exposure:** The percentage of AUM (Assets Under Management) allocated to a particular strategy or investment.
+
+**Calculation:**
+```
+Exposure % = (Allocated Amount / Vault AUM) × 100
+```
+
+**Three levels of exposure limits:**
+
+1. **Per-Vault Exposure:** Maximum allocation to any single strategy within a vault
+2. **Per-Strategy Exposure:** Maximum total allocation to a strategy across all vaults
+3. **Cross-Vault Exposure:** Total platform exposure in any strategy
+
+### Example Scenario
+
+```
+Platform AUM: $100M
+
+Vault A: $30M AUM
+├─ Strategy X: $9M (30% of Vault A) ✓ Within limit
+└─ Strategy Y: $6M (20% of Vault A) ✓ Within limit
+
+Vault B: $20M AUM
+├─ Strategy X: $8M (40% of Vault B) ❌ Exceeds 30% per-vault limit
+└─ Strategy Y: $4M (20% of Vault B) ✓ Within limit
+
+Platform Strategy X: $9M + $8M = $17M
+├─ Percentage of total platform AUM: (17M / 100M) × 100 = 17% ✓ Within 20% limit
+```
+
+## Default Exposure Limits
+
+| Limit Type | Default | Configuration |
+|---|---|---|
+| Per-Vault Maximum | 30% | MAX_SINGLE_VAULT_EXPOSURE_PCT |
+| Per-Strategy Maximum | 20% | MAX_STRATEGY_EXPOSURE_PCT |
+| Cross-Vault Maximum | 50% | MAX_CROSS_VAULT_EXPOSURE_PCT |
+| Exposure Calculation | Notional | EXPOSURE_TYPE |
+
+### Exposure Types
+
+**Notional:** Simple percentage of AUM (default)
+```
+exposure = allocation_amount / vault_aum * 100
+```
+
+**Risk-Weighted:** Adjusts for strategy risk profile
+```
+exposure = (allocation_amount * risk_factor) / vault_aum * 100
+```
+
+**Value-at-Risk (VAR):** Conservative worst-case estimate
+```
+exposure = (allocation_amount * var_factor) / vault_aum * 100
+```
+
+## Validation Flow
+
+```
+User attempts allocation
+         ↓
+Validate exposure within limits
+    ├─ Per-vault check
+    ├─ Per-strategy check
+    └─ Cross-vault check
+         ↓
+    ┌─────────────┐
+    │   All OK?   │
+    └─────────────┘
+      /           \
+    YES            NO
+    ↓              ↓
+Success         Error response
+                + Record breach
+                + Suggest safe amount
+                + Trigger alert
+```
+
+## API Usage
+
+### Check Exposure Before Allocation
+
+```typescript
+import { validateExposure } from './exposureGuardrails';
+import Decimal from 'decimal.js';
+
+const result = await validateExposure(
+  'vault_123',
+  'strategy_456',
+  new Decimal('1000000') // $1M allocation
+);
+
+if (!result.canAllocate) {
+  res.status(400).json({
+    error: 'Exposure limit exceeded',
+    message: result.message,
+    currentExposure: result.currentExposurePct,
+    availableCapacity: result.availableCapacityPct,
+    maxAllowable: result.remainingCapacity.toString(),
+  });
+} else {
+  // Proceed with allocation
+}
+```
+
+### Get Vault Exposure Summary
+
+```typescript
+import { getVaultExposureSummary } from './exposureGuardrails';
+
+const summary = await getVaultExposureSummary('vault_123');
+// {
+//   vaultId: 'vault_123',
+//   vaultAum: Decimal('30000000'),
+//   allocations: [
+//     { strategyId: 'strat_1', exposure: Decimal('9000000'), exposurePct: 30 },
+//     { strategyId: 'strat_2', exposure: Decimal('5000000'), exposurePct: 16.67 }
+//   ],
+//   totalExposure: Decimal('14000000'),
+//   totalExposurePct: 46.67,
+//   headroom: Decimal('16000000'),
+//   headroomPct: 53.33
+// }
+```
+
+## Endpoint Integration
+
+### Strategy Allocation Endpoint
+
+```typescript
+POST /api/vaults/{vaultId}/strategies/{strategyId}/allocate
+Content-Type: application/json
+
+{
+  "amount": "1000000"

+```
+
+**Response (Success - 200 OK):**
+```json

+}
+```
+
+## Risk Scenarios & Responses
+
+### Scenario 1: User Tries to Exceed Per-Vault Limit
+
+**Situation:**
+- Vault AUM: $10M
+- Current allocation to Strategy X: $3M (30% - at limit)
+- User tries to allocate: $500K more to Strategy X
+
+**System Response:**
+1. Validates: $3.5M / $10M = 35% > 30% ❌
+2. Blocks allocation
+3. Returns error with max safe amount: $0
+4. Suggests other strategies with available capacity
+5. Records breach attempt in audit log
+
+### Scenario 2: Cross-Vault Exposure Accumulation
+
+**Situation:**
+- Platform AUM: $100M
+- Strategy X current exposure: $19M (19% - near 20% limit)
+- Vault A wants to allocate: $1.5M to Strategy X
+
+**System Response:**
+1. Validates: ($19M + $1.5M) / $100M = 20.5% > 20% ❌
+2. Calculates max safe: $1M
+3. Suggests allocation of $1M instead
+4. User can proceed with $1M or choose different strategy
+
+### Scenario 3: Risk-Weighted Exposure
+
+**Situation:**
+- Vault AUM: $50M
+- Conservative Strategy (risk factor 0.8)
+- Aggressive Strategy (risk factor 2.0)
+- Allocation limit: 30%
+
+**Calculations:**
+```
+Conservative: $15M × 0.8 = $12M exposure
+Risk-adjusted: $12M / $50M = 24% of limit ✓
+
+Aggressive: $15M × 2.0 = $30M exposure
+Risk-adjusted: $30M / $50M = 60% of limit ❌ Blocked at $7.5M
+```
+
+## Guardrail Adjustment Process
+
+### When to Adjust Limits
+
+**Increase limits if:**
+- Historical breaches < 1% of allocation attempts
+- Risk management approves increased exposure
+- Strategic rationale for broader allocation
+- Market conditions support more diversification
+
+**Decrease limits if:**
+- Multiple breach attempts detected
+- Strategy performance degradation
+- Increased correlation with other allocations
+- Regulatory or compliance requirement
+
+### Adjustment Process
+
+1. **Analysis Phase** (1 day)
+   - Review breach patterns and rationale
+   - Analyze strategy correlation matrix
+   - Get risk committee approval
+
+2. **Configuration Phase** (30 min)
+   - Update environment variables or database
+   - Document change and rationale
+   - Set monitoring alerts on new limits
+
+3. **Rollout Phase** (15 min)
+   - Update in staging environment first
+   - Validate monitoring alerts trigger correctly
+   - Deploy to production during low-traffic window
+
+4. **Monitoring Phase** (ongoing)
+   - Track allocation patterns
+   - Monitor for edge cases
+   - Review weekly for first month
+
+### Example: Adjusting Strategy Limits
+
+**Before:**
+```bash
+MAX_STRATEGY_EXPOSURE_PCT=20
+```
+
+**After Analysis:** Risk team approves 25% for Stellar LP Yield (low volatility)
+```bash
+STRATEGY_OVERRIDES='{
+  "stellar_lp_yield": {
+    "platformLimit": 25,
+    "perVaultLimit": 35
+  }
+}'
+```
+
+**Monitoring:**
+```promql
+# Alert if exposure exceeds 22.5% (90% of 25%)
+ALERT exposure_high
+  IF strategy_exposure_pct{strategy="stellar_lp_yield"} > 22.5
+  FOR 5m
+```
+
+## Compliance & Audit
+
+### Exposure Breach Audit Trail
+
+```sql
+SELECT 
+  timestamp,
+  vault_id,
+  strategy_id,
+  attempted_amount,
+  current_exposure_pct,
+  limit_pct,
+  reason
+FROM exposure_breaches
+ORDER BY timestamp DESC;
+```
+
+### Reports
+
+**Weekly Exposure Report:**
+```
+Strategy A: 18% exposure (limit: 20%) - 2 breach attempts
+Strategy B: 12% exposure (limit: 20%) - 0 breach attempts
+Strategy C: 45% exposure (limit: 50%) - 5 breach attempts
+
+Top 5 strategies by exposure:
+1. Stellar LP Yield: 18%
+2. Yield Farming: 15%
+3. Validator Staking: 12%
+...
+
+Recommendations:
+- Strategy C approaching limit; consider rebalancing
+- Diversify into lower-exposure strategies
+```
+
+## Testing
+
+### Unit Tests for Exposure Validation
+
+```typescript
+describe('exposureGuardrails', () => {
+  it('should allow allocation within per-vault limit', async () => {
+    const result = await validateExposure(vaultId, strategyId, amount);
+    expect(result.canAllocate).toBe(true);
+  });
+
+  it('should block allocation exceeding per-vault limit', async () => {
+    const result = await validateExposure(vaultId, strategyId, excessiveAmount);
+    expect(result.canAllocate).toBe(false);
+    expect(result.message).toContain('per-vault');
+  });
+
+  it('should calculate cross-vault exposure correctly', async () => {
+    // Test with multiple vaults
+  });
+});
+```

+# Idempotency Support & Request Deduplication
+
+**Status**: Implementation Complete  
+**Related Issues**: #1003 (Idempotency Keys), #1004 (Duplicate Prevention)  
+**Acceptance Criteria**: ✓ All criteria met
+
+## Overview
+
+Prevents duplicate state changes from repeated or retried requests. Implements idempotency key tracking for critical mutation endpoints, ensuring that retried submissions produce safe, idempotent results.
+
+## Architecture
+
+### Core Components
+
+#### 1. **Key Validation** (`validateIdempotencyKey`)
+Validates format and entropy of idempotency keys.
+
+```typescript
+// Accepts UUID v4 format
+validateIdempotencyKey('550e8400-e29b-41d4-a716-446655440000'); // ✓
+
+// Accepts hex-encoded nonces
+validateIdempotencyKey('a'.repeat(32)); // ✓
+
+// Accepts alphanumeric with dashes/underscores
+validateIdempotencyKey('my-idempotency-key-12345678'); // ✓
+
+// Rejects short keys
+validateIdempotencyKey('short'); // ✗
+
+// Rejects invalid characters
+validateIdempotencyKey('key-@-invalid'); // ✗
+```
+
+**Constraints**:
+- Minimum length: 16 characters (prevents brute-force)
+- Maximum length: 256 characters (prevents abuse)
+- Pattern: UUID v4, hex nonce, or alphanumeric + dashes/underscores
+
+#### 2. **Request Hashing** (`hashRequestBody`)
+Generates deterministic SHA-256 hashes of request bodies for duplicate detection.
+
+```typescript
+const body1 = { amount: '1000', wallet: 'G123' };
+const body2 = { amount: '1000', wallet: 'G123' };
+
+hashRequestBody(body1) === hashRequestBody(body2); // true (identical)
+
+const body3 = { amount: '2000', wallet: 'G123' };
+hashRequestBody(body1) === hashRequestBody(body3); // false (different)
+```
+
+#### 3. **Record Storage** (`IdempotencyRecord`)
+Tracks request/response pairs with lifecycle states.
+
+```typescript
+interface IdempotencyRecord {
+  keyId: string;                    // Unique idempotency key
+  status: 'pending' | 'completed' | 'failed';
+  requestHash: string;              // SHA-256 of request body
+  responseHash?: string;            // SHA-256 of response
+  responseBody?: unknown;           // Cached response (if completed)
+  statusCode?: number;              // HTTP status code
+  createdAt: Date;                  // Submission time
+  completedAt?: Date;               // Completion time
+  expiresAt: Date;                  // TTL (24h default)
+  tenantId: string;                 // Tenant scope
+  walletAddress?: string;           // Optional user scope
+  operation: string;                // Operation type
+}
+```
+
+States:
+- **pending**: Request is being processed
+- **completed**: Request succeeded; response cached
+- **failed**: Request failed; error cached
+
+#### 4. **Middleware** (`enforceIdempotency`)
+Express middleware that prevents duplicate submissions.
+
+```typescript
+router.post(
+  '/v1/vault/deposit',
+  enforceIdempotency(),  // Required for mutations
+  handler
+);
+```
+
+## API Usage
+
+### Deposit with Idempotency
+
+```bash
+# First submission (succeeds)
+curl -X POST https://api.yieldvault.com/v1/vault/deposit \
+  -H "Authorization: Bearer $TOKEN" \

+# {
+#   "txnId": "txn-123",
+#   "status": "completed",
+#   "amount": "1000"
+# }
+
+# Retry with same key (returns cached response)
+curl -X POST https://api.yieldvault.com/v1/vault/deposit \

+}
+```
+
+## Implementation Details
+
+### Database Schema
+
+```sql
+CREATE TABLE idempotencyKey (
+  keyId TEXT PRIMARY KEY,
+  tenantId TEXT NOT NULL,
+  walletAddress TEXT,
+  operation TEXT NOT NULL,
+  status TEXT NOT NULL, -- 'pending', 'completed', 'failed'
+  
+  requestHash TEXT NOT NULL,     -- SHA-256 of request body
+  responseHash TEXT,              -- SHA-256 of response
+  responseBody JSONB,             -- Cached response (if completed)
+  statusCode INTEGER,
+  
+  createdAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  completedAt TIMESTAMP,
+  expiresAt TIMESTAMP NOT NULL,   -- Defaults to NOW() + 24h
+  
+  FOREIGN KEY (tenantId) REFERENCES tenant(id),
+  INDEX (tenantId, expiresAt),
+  INDEX (keyId, tenantId)
+);
+```
+
+### Request Lifecycle
+
+```
+Client Submits Request
+    ↓
+[extractTenantContext] Sets req.tenantId
+    ↓
+[enforceIdempotency] Checks Idempotency-Key header
+    ├─ Missing → 400 Bad Request
+    ├─ Invalid → 400 Invalid Format
+    └─ Valid → Check database
+        ├─ Not found → Create pending record
+        │   ↓
+        │   Handler processes request
+        │   ├─ Success → completeIdempotencyRecord()
+        │   │   ↓
+        │   │   Returns 200 (cached for retries)
+        │   └─ Failure → failIdempotencyRecord()
+        │       ↓
+        │       Returns error (cached for retries)
+        │
+        ├─ Pending → 409 Conflict (request processing)
+        │   ↓
+        │   Client should wait and retry
+        │
+        ├─ Completed → Compare request hash
+        │   ├─ Same → Return cached 200 response
+        │   └─ Different → 409 Conflict (collision)
+        │
+        └─ Failed → Compare request hash
+            ├─ Same → Return cached error response
+            └─ Different → 409 Conflict (collision)
+
+Periodic Cleanup (hourly)
+    ↓
+[cleanupExpiredIdempotencyKeys] Deletes expired records (>24h old)
+```
+
+### Request Hash Algorithm
+
+```typescript
+// SHA-256 of normalized JSON
+function hashRequestBody(body: unknown): string {
+  const normalized = typeof body === 'object' 
+    ? JSON.stringify(body)  // Note: order-dependent
+    : String(body);
+  
+  return crypto
+    .createHash('sha256')
+    .update(normalized)
+    .digest('hex');  // 64-char hex string
+}
+```
+
+**Important**: Request order must be deterministic. If the frontend re-orders JSON keys, the hash will differ.
+
+```typescript
+// Same body, same hash
+const hash1 = hashRequestBody({ a: 1, b: 2 });
+const hash2 = hashRequestBody({ a: 1, b: 2 });
+// hash1 === hash2 ✓
+
+// Different order = different hash (current behavior)
+const hash3 = hashRequestBody({ b: 2, a: 1 });
+// hash1 === hash3 // false (JSON order matters)
+```
+
+## Client Implementation Guide
+
+### JavaScript/TypeScript
+
+```typescript
+import { v4 as uuidv4 } from 'uuid';
+
+async function depositWithIdempotency(amount: string, wallet: string) {
+  const idempotencyKey = uuidv4();  // Generate unique key
+  
+  try {
+    const response = await fetch(
+      'https://api.yieldvault.com/v1/vault/deposit',
+      {
+        method: 'POST',
+        headers: {
+          'Authorization': `Bearer ${token}`,
+          'Idempotency-Key': idempotencyKey,  // Include key
+          'Content-Type': 'application/json',
+        },
+        body: JSON.stringify({
+          amount,
+          walletAddress: wallet,
+        }),
+      }
+    );
+    
+    if (response.status === 409) {
+      // Conflict - either collision or still pending
+      const error = await response.json();
+      
+      if (error.code === 'IDEMPOTENCY_PENDING') {
+        // Wait and retry
+        await sleep(error.retryAfter * 1000);
+        return depositWithIdempotency(amount, wallet);  // Retry with same key
+      } else if (error.code === 'IDEMPOTENCY_KEY_COLLISION') {
+        // Different request with same key
+        throw new Error('Request body mismatch; use new Idempotency-Key');
+      }
+    }
+    
+    return await response.json();
+  } catch (error) {
+    console.error('Deposit failed:', error);
+    throw error;
+  }
+}
+
+// Usage
+const result = await depositWithIdempotency('1000.00', 'GXXX...');
+console.log('Transaction:', result.txnId);
+
+// Retry is safe (same response)
+const result2 = await depositWithIdempotency('1000.00', 'GXXX...');
+// Same idempotency key? Same response guaranteed
+```
+
+### Python
+
+```python
+import uuid
+import requests
+from time import sleep
+
+def deposit_with_idempotency(token, amount, wallet):
+    idempotency_key = str(uuid.uuid4())
+    
+    while True:
+        response = requests.post(
+            'https://api.yieldvault.com/v1/vault/deposit',
+            headers={
+                'Authorization': f'Bearer {token}',
+                'Idempotency-Key': idempotency_key,
+                'Content-Type': 'application/json',
+            },
+            json={
+                'amount': amount,
+                'walletAddress': wallet,
+            },
+            timeout=30
+        )
+        
+        if response.status_code == 200:
+            return response.json()
+        
+        if response.status_code == 409:
+            error = response.json()
+            
+            if error['code'] == 'IDEMPOTENCY_PENDING':
+                # Wait and retry
+                retry_after = error.get('retryAfter', 30)
+                sleep(retry_after)
+                continue
+            else:
+                raise Exception(f"Idempotency collision: {error['message']}")
+        
+        # Other errors
+        response.raise_for_status()
+
+# Usage
+result = deposit_with_idempotency(token, '1000.00', 'GXXX...')
+print(f"Transaction: {result['txnId']}")
+```
+
+## Cleanup & Maintenance
+
+### Automatic Cleanup
+
+Expired idempotency records (> 24 hours old) are automatically cleaned up:
+
+```typescript
+// Runs every hour
+startIdempotencyCleanupTask(3600000);
+
+// Or manually trigger
+await cleanupExpiredIdempotencyKeys();
+```
+
+### Monitoring
+
+```bash
+# Check pending requests
+SELECT COUNT(*) FROM idempotencyKey WHERE status = 'pending';
+
+# Check key distribution
+SELECT operation, COUNT(*) FROM idempotencyKey 
+GROUP BY operation;
+
+# Monitor expiry
+SELECT 
+  operation,
+  COUNT(*) as total,
+  AVG(EXTRACT(EPOCH FROM (expiresAt - createdAt))/3600) as avg_ttl_hours
+FROM idempotencyKey
+WHERE createdAt > NOW() - INTERVAL 24 HOUR
+GROUP BY operation;
+```
+
+## Testing
+
+### Unit Tests
+```bash
+npm test -- idempotency.test.ts
+```
+
+Coverage:
+- ✓ UUID v4 validation
+- ✓ Hex nonce validation
+- ✓ Custom key validation
+- ✓ Request hashing determinism
+- ✓ Response caching
+- ✓ Collision detection
+- ✓ Pending request handling
+
+### Integration Tests
+```bash
+npm test -- integration/idempotency.test.ts
+```
+
+Scenarios:
+- ✓ First submission succeeds
+- ✓ Identical retry returns cached response
+- ✓ Different request with same key rejected
+- ✓ Pending request returns 409
+- ✓ Failed request cached and reused
+- ✓ Key expiry after 24 hours
+
+### Manual Testing
+
+```bash
+# Generate idempotency key
+KEY=$(uuidgen)
+
+# First submission
+curl -X POST https://localhost:3000/v1/vault/deposit \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Idempotency-Key: $KEY" \
+  -d '{"amount":"1000","walletAddress":"G..."}' \
+  --write-out '\n%{http_code}\n'
+# Returns 200 with txnId
+
+# Immediate retry (cached)
+curl -X POST https://localhost:3000/v1/vault/deposit \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Idempotency-Key: $KEY" \
+  -d '{"amount":"1000","walletAddress":"G..."}' \
+  --write-out '\n%{http_code}\n'
+# Returns 200 with same txnId (response cached)
+
+# Different body, same key
+curl -X POST https://localhost:3000/v1/vault/deposit \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Idempotency-Key: $KEY" \
+  -d '{"amount":"2000","walletAddress":"G..."}' \
+  --write-out '\n%{http_code}\n'
+# Returns 409 Conflict
+```
+
+## Performance & Scaling
+
+- **Storage**: ~2KB per idempotency record
+- **Lookup**: ~5ms (indexed by keyId + tenantId)
+- **Hash generation**: ~1ms per request
+- **TTL storage**: 24 hours (configurable)
+- **Cleanup overhead**: <1% CPU (hourly background task)
+
+For high-volume deployments:
+- Use Redis for faster lookups (optional)
+- Tune cleanup frequency based on volume
+- Archive old records monthly

+| P95 Latency | > 2500ms for 15+ min | Post to #alerts |
+| Vault Inactive | TVL = 0 for 24h | Daily report |
+
+## Usage Examples
+
+### Support Team: Investigate Vault Issue
+
+```
+Support receives alert: "vault-123 failure rate > 10%"
+
+1. Check dashboard:
+   GET /admin/health/dashboard
+   ↓
+   Sees: 250 failures/24h, mostly "timeout" (200) and 
+         "network_error" (50)
+
+2. Correlate with:
+   - P95 latency: 3500ms (normally 1250ms)
+   - Soroban RPC dependency: DOWN
+   
+3. Action:
+   - Escalate: "Soroban RPC unavailable"
+   - Notify backend team
+   - Update customer: "Experiencing delays due to RPC issues"
+
+4. Resolution:
+   - Soroban RPC restored
+   - Failure rate returns to normal (4.2%)
+   - Document in postmortem
+```
+
+### Operations: Monitor System Health
+
+```
+Morning standup check:
+
+curl -s https://api.yieldvault.com/admin/health/dashboard | jq '.'
+
+Output:
+{
+  "system": {
+    "status": "healthy",
+    "totalTvlUsd": 250000000,
+    "dependencies": {
+      "database": "up",
+      "soroban_rpc": "up",
+      "redis": "up"
+    }
+  },
+  "vaults": [
+    // All healthy
+  ]
+}
+
+→ Everything normal, no action needed
+```
+
+### Engineering: Detect Performance Regression
+
+```
+Engineer reviews metrics trend:
+
+Last 7 days P95 latency:
+- Mon: 1100ms
+- Tue: 1200ms
+- Wed: 1850ms ← Spike after deployment
+- Thu: 2100ms ← Getting worse
+- Fri: 2300ms
+
+Action:
+1. Check deployment on Wed
+2. Identify: New webhook signature validation logic
+3. Optimize or rollback
+4. Restore P95 to 1200ms
+```
+
+## Testing & Validation
+
+### Unit Tests
+```bash
+npm test -- operationalMetrics.test.ts
+```
+
+Coverage:
+- ✓ Activity metric collection (deposits, withdrawals)
+- ✓ Failure rate calculation
+- ✓ Latency percentile calculation
+- ✓ Health status determination
+- ✓ Dependency health aggregation
+
+### Integration Tests
+```bash
+npm test -- integration/operational-metrics.test.ts
+```
+
+Scenarios:
+- ✓ Metrics sync every 60 seconds
+- ✓ Dashboard endpoint returns current data
+- ✓ Health status updates correctly
+- ✓ Failure rate threshold detection
+- ✓ Latency trend tracking
+
+### Manual Testing
+
+```bash
+# 1. Check Prometheus metrics
+curl http://localhost:3000/metrics | grep "vault_"
+
+# Output should include:
+# vault_activity_deposits_total_24h{vault_id="vault-123",tenant_id="tenant-456"} 152
+# vault_activity_withdrawals_total_24h{vault_id="vault-123",tenant_id="tenant-456"} 89
+# vault_failure_rate{vault_id="vault-123",failure_type="total"} 4.2
+# vault_latency_p95_ms{vault_id="vault-123",operation="deposit"} 1250
+
+# 2. Check health dashboard
+curl -H "Authorization: ApiKey sk-admin-..." \
+  http://localhost:3000/admin/health/dashboard | jq '.system'
+
+# 3. Monitor metrics sync
+tail -f logs/backend.log | grep "metrics_sync"
+```
+
+## Performance Considerations
+
+- **Collection overhead**: ~50-100ms per vault (DB queries)
+- **Sync frequency**: 60 seconds (configurable)
+- **Storage**: Metrics stored in-memory (Prometheus scrapes)
+- **Historical retention**: Managed by Prometheus (default 15 days)
+
+For high-scale deployments (100+ vaults):
+- Consider sampling subset of vaults per sync
+- Archive metrics to long-term storage
+- Use metrics pre-aggregation
+
+## Configuration
+
+### Environment Variables
+
+```bash
+# Metrics sync interval (milliseconds)
+METRICS_SYNC_INTERVAL_MS=60000
+
+# Enable/disable operational metrics
+OPERATIONAL_METRICS_ENABLED=true
+
+# Latency threshold for "unhealthy" status (ms)
+LATENCY_UNHEALTHY_THRESHOLD=5000
+
+# Failure rate threshold for "unhealthy" (percent)
+FAILURE_RATE_UNHEALTHY_THRESHOLD=10
+```
+
+## Data Privacy
+
+- Metrics include aggregate counts, no PII
+- Wallet addresses not exposed in metrics
+- Tenant scope enforced (only authorized admins see metrics)
+- No individual transaction details in metrics
+- Historical metrics retained per data retention policy

+# Prisma migration workflow
+
+Schema changes for the YieldVault API are version-controlled under
+`backend/prisma/migrations`. Do not edit the live database by hand.
+
+## Layout
+
+```
+backend/prisma/
+  schema.prisma          # source of truth
+  migrations/
+    0_init/              # baseline of the existing schema
+    <timestamp>_<name>/
+      migration.sql
+    migration_lock.toml
+  rollbacks/             # optional down SQL, named after the forward migration
+```
+
+Legacy SQL scripts (non-Prisma) live in `backend/migrations/` and are applied
+with `npm run db:migrate` against Postgres.
+
+## Everyday commands
+
+Run from `backend/`:
+
+| Script | Purpose |
+| --- | --- |
+| `npm run prisma:generate` | Regenerate the Prisma client |
+| `npm run prisma:schema-check` | Validate the schema and fail if committed migrations do not produce it |
+| `npm run prisma:migrate -- --name add_foo` | Create a migration from `schema.prisma` (dev) |
+| `npm run prisma:deploy` | Apply pending migrations (CI / prod) |
+| `npm run prisma:status` | Show applied vs pending |
+| `npm run prisma:rollback -- --name <migration>` | Apply down SQL and mark rolled back |
+| `npm run check:migrations:canary` | Reject unsafe canary-breaking SQL |
+
+Create a change:
+
+1. Edit `backend/prisma/schema.prisma`.
+2. `npm run prisma:migrate -- --name describe_the_change`.
+3. Review the generated `migration.sql`.
+4. Add a matching file in `prisma/rollbacks/<migration_folder>.sql` if the
+   change is reversible.
+5. Commit schema, migration, and rollback together.
+
+The backend governance workflow runs `prisma:schema-check` on every pull
+request that changes the backend or migration workflow. The check validates
+`schema.prisma`, then compares the final state represented by
+`prisma/migrations` with the schema datamodel. A non-zero result means the
+schema was changed without a matching migration, a migration was edited after
+being applied, or a migration folder is incomplete. Do not bypass this check
+by editing generated or deployed database state; create and commit the proper
+forward migration instead.
+
+Existing schema is already captured by `0_init` plus follow-up migrations.
+New environments run `prisma:deploy` (SQLite/dev) or `db:migrate` (Postgres).
+
+## Testing
+
+- `backend/src/__tests__/prismaMigrationWorkflow.test.ts` asserts every
+  migration folder has `migration.sql` and that rollback files parse.
+- `backend/src/__tests__/canaryMigrationCheck.test.ts` covers unsafe SQL
+  detection.
+- CI runs `node scripts/check-migrations.js` and `npm run check:migrations:canary`.
+
+## Rollback procedures
+
+Prisma does not generate automatic down migrations. Rollback is explicit:
+
+1. **Expand/contract (preferred):** ship a new forward migration that restores
+   compatibility (re-add a column, backfill, then drop the new one later).
+2. **Documented down SQL:**
+   ```bash
+   cd backend
+   npm run prisma:rollback -- --name 20260530020000_add_webhook_verification
+   ```
+   The script applies `prisma/rollbacks/<name>.sql` inside a transaction, then
+   runs `prisma migrate resolve --rolled-back <name>` so the migration can be
+   re-applied later.
+3. **Failed deploy (never applied):** `npx prisma migrate resolve --rolled-back <name>`
+   without running SQL.
+4. **Restore from backup** if the change is destructive (`DROP TABLE`, data
+   rewrite). See `docs/runbooks/rollback-and-hotfix.md`.
+
+Never `DROP` or `TRUNCATE` in a canary window. Follow
+`docs/CANARY_MIGRATION_STRATEGY.md`.
+
+## Drift recovery
+
+When CI reports schema drift:
+
+1. Run `npm run prisma:schema-check` from `backend/` and inspect the diff.
+2. If `schema.prisma` is ahead, create a named migration with
+  `npm run prisma:migrate -- --name <description>` and commit its
+  `migration.sql`.
+3. If a committed migration was edited after deployment, restore its original
+  SQL and create a new corrective migration. Never rewrite an applied
+  migration to make the check pass.
+4. Check the target with `npm run prisma:status`. For a failed deployment,
+  resolve the migration only after confirming whether any SQL was applied.
+5. Use the documented rollback SQL or restore a verified backup for destructive
+  changes, then deploy the corrective forward migration and rerun the checks.
+
+For an unapplied migration, use:
+
+```bash
+npx prisma migrate resolve --schema prisma/schema.prisma --rolled-back <name>
+```
+
+For an applied migration with a rollback file, use
+`npm run prisma:rollback -- --name <name>` and follow the script output. Take a
+backup and coordinate production recovery before running destructive rollback
+SQL.

+
+## Security Features
+
+### Refresh Token Rotation (Issue #377)
+
+**Why:** Limits the window of opportunity for attackers who compromise a token
+
+**How:**
+1. Client receives refresh token
+2. Client uses refresh token → new refresh token issued, old one revoked immediately
+3. Client stores new refresh token, discards old one
+4. If attacker replays old token, it's already revoked → error returned
+
+**Recovery:** New session required (logout and re-authenticate)
+
+### Replay Attack Detection
+
+**Scenario:** Attacker intercepts refresh token and replays it
+
+**Protection:**
+1. Token ID (jti) recorded when token created
+2. When refresh token used, old token ID marked as revoked
+3. If attacker replays old token ID, it's checked against revocation list
+4. Old token ID found in revocation list → 401 Unauthorized
+
+**Response:** Session audit event recorded, suspicious activity score increased
+
+### Concurrent Refresh Handling
+
+**Scenario:** Network delay causes client to retry refresh request while first request still processing
+
+**Protection:**
+1. Lock acquired on session during refresh
+2. Second request waits for lock
+3. First request completes, issues new tokens, revokes old
+4. Second request reads lock, sees old token was revoked
+5. Second request returns 401, prompts re-login
+
+### Token Expiration Handling
+
+**Access Token Expiration:**
+- Client receives 401 from API
+- Client automatically refreshes token (silent refresh)
+- Retries original request
+- User unaware of token refresh
+
+**Refresh Token Expiration:**
+- Client tries to refresh, receives 401
+- No valid refresh token available
+- Session ended, user must log in again
+- UI prompts "Session expired, please log in again"
+
+## Session Audit Trail
+
+All session events recorded and queryable:
+
+```typescript
+GET /api/wallets/{address}/sessions
+```
+
+Returns:
+```json
+{
+  "events": [
+    {
+      "timestamp": "2024-08-25T10:30:00Z",
+      "eventType": "created",
+      "reason": "login_success",
+      "ipAddress": "203.0.113.42",
+      "userAgent": "Mozilla/5.0...",
+      "sessionId": "session_123"
+    },
+    {
+      "timestamp": "2024-08-25T10:32:15Z",
+      "eventType": "refreshed",
+      "reason": "refresh_success",
+      "ipAddress": "203.0.113.42",
+      "sessionId": "session_123"
+    }
+  ]
+}
+```
+
+### Suspicious Activity Detection
+
+System automatically analyzes session patterns:
+
+- Multiple failed login attempts (3+ in 24h)
+- Activity from multiple IP addresses
+- Activity from multiple user agents
+- Rapid token refreshes (> 20 in 24h)
+- Unusual time-of-day activity
+
+When suspicious activity detected:
+1. Recorded in audit log
+2. Session marked with risk score (0-1)
+3. User notified via email
+4. Additional MFA may be required
+
+## Session Recovery
+
+### User Suspects Account Compromise
+
+**Steps:**
+1. User navigates to /security/sessions
+2. Views session history and active sessions
+3. Can revoke any session (logout other devices)
+4. Can see suspicious activity warnings
+
+**Backend response:**
+- Revokes specified session immediately
+- Revocation event logged with reason "user_initiated"
+- Email confirmation sent
+
+### Session Recovery After Suspicious Activity
+
+**System detects compromise:**
+1. Automatic alerts to ops team
+2. Session flagged as compromised
+3. User receives email notification
+4. Tokens for that session revoked
+5. User required to re-authenticate
+
+**Recovery steps:**
+1. User clicks "Re-authenticate" link in email
+2. Completes wallet signature verification (challenge-response)
+3. New clean session established
+4. Audit event: "session_created_after_compromise"
+
+### Investigating Session History
+
+**Support workflow:**
+```bash
+# Get all sessions for wallet
+GET /api/admin/wallets/{address}/session-history
+
+# Get details for specific session
+GET /api/admin/sessions/{sessionId}
+
+# Export for compliance
+GET /api/admin/wallets/{address}/session-export?format=csv
+```
+
+## Environment Variables

+JWT_REFRESH_TTL_SECONDS=604800
+
+# JWT signing secret (REQUIRED in production, min 32 chars, 3+ char classes)
+JWT_SECRET="your-secure-secret-here-min-32-chars-upper-lower-digits-symbols"

+// Store refresh token in HttpOnly cookie (set by server)
+// Store access token in memory only (cleared on page reload)
+
+async function makeAuthenticatedRequest(url: string) {
+  let response = await fetch(url, {
+    headers: { Authorization: `Bearer ${accessToken}` },
+    credentials: 'include', // Include cookies (refresh token)
+  });
+
+  if (response.status === 401) {
+    // Access token expired, refresh
+    const refreshResponse = await fetch('/auth/refresh', {
+      method: 'POST',
+      credentials: 'include',
+    });
+
+    if (refreshResponse.ok) {
+      const { accessToken: newToken } = await refreshResponse.json();
+      accessToken = newToken;
+
+      // Retry original request
+      response = await fetch(url, {
+        headers: { Authorization: `Bearer ${accessToken}` },
+        credentials: 'include',
+      });
+    } else {
+      // Refresh failed, must log in again
+      redirectToLogin();
+    }
+  }
+
+  return response;
+}
+```
+
+### Mobile Client (Native App)
+
+```typescript
+// Store both tokens securely in platform keychain
+// Access token: short-lived in memory
+// Refresh token: persisted in secure storage
+
+async function makeAuthenticatedRequest(url: string) {
+  let response = await fetch(url, {
+    headers: { Authorization: `Bearer ${accessToken}` },
+  });
+
+  if (response.status === 401) {
+    // Try to refresh
+    const newTokens = await refreshAccessToken();
+    if (newTokens) {
+      accessToken = newTokens.accessToken;
+      await saveToKeychain('refreshToken', newTokens.refreshToken);
+
+      // Retry original request
+      response = await fetch(url, {
+        headers: { Authorization: `Bearer ${accessToken}` },
+      });
+    } else {
+      // Refresh failed, prompt login
+      showLoginScreen();
+    }
+  }
+
+  return response;
+}
+```
+
+## Troubleshooting
+
+### "Invalid refresh token" Error
+
+**Causes:**
+1. Token already rotated (another request used it first)
+2. Token expired (7 days passed)
+3. User logged out (token revoked)
+4. Session compromised (token revoked by system)
+
+**Solution:**
+- Clear stored tokens
+- Redirect to login
+- User must re-authenticate
+
+### "Session already in use" (Concurrent Refresh)
+
+**Cause:** Multiple refresh requests in rapid succession
+
+**Solution:**
+- Automatically handled by backend (returns same new tokens)
+- Client implementation should retry with new token
+
+### "Suspicious activity detected"
+
+**Cause:** System detected unusual pattern
+
+**Solution:**
+1. Check email for notification
+2. Review session history at `/security/sessions`
+3. Revoke suspicious sessions
+4. Re-authenticate to create new clean session
+
+## Compliance & Audit
+
+- All session events logged with timestamp and context
+- Audit log retention: 90 days (configurable)
+- GDPR: Users can export their session history
+- SOC2: Session audit logs available for compliance audits
+- Suspicious activity alerts available via API

+# Slow Query Monitoring & Performance Budget Guide
+
+## Overview
+
+YieldVault implements query performance budgets to proactively identify slow database operations before they impact production. Each query type has a maximum allowed execution time; exceeding this triggers alerts and logging.
+
+## Performance Budgets
+
+### Default Budgets
+
+| Operation Type | Budget | Notes |
+|---|---|---|
+| Read operations (find, count) | 100ms | Single record retrieval |
+| Write operations (create, update) | 200ms | Data modification |
+| Complex reads (findMany) | 150ms | Multiple records |
+| Aggregations | 200ms | Group by, count, etc. |
+| Transaction commit | 300ms | Multi-step transaction |
+
+### Query-Specific Budgets
+
+Built-in optimized budgets for hot paths:
+
+```typescript
+'User.findUnique': 50ms
+'VaultState.findUnique': 50ms
+'SharePriceSnapshot.create': 150ms
+'Transaction.findMany': 150ms
+'Referral.findUnique': 50ms
+'WebhookEndpoint.findMany': 100ms
+'WebhookDelivery.findMany': 150ms
+```
+
+### Custom Budgets via Environment
+
+```bash
+# JSON format with query names and budgets (ms)
+QUERY_BUDGETS_JSON='{
+  "User.findMany": 120,
+  "VaultPosition.aggregate": 180,
+  "CustomReport.generate": 500
+}'
+```
+
+## Breach Severity
+
+### Warning Level (1.0x - 2.0x budget)
+- Logged as warning
+- Tagged in metrics
+- Rate-limited alerts (1 per 15 min per query)
+
+**Example:** Query takes 150ms, budget is 100ms (1.5x)
+- Severity: warning
+- Alert sent to Slack (if configured)
+- Metrics increment warning counter
+
+### Critical Level (> 2.0x budget)
+- Logged as error
+- Immediate alert
+- Escalated to PagerDuty (if configured)
+- Performance investigation recommended
+
+**Example:** Query takes 250ms, budget is 100ms (2.5x)
+- Severity: critical
+- Error logged
+- Alert sent to Slack + PagerDuty
+- Ops team notified
+
+## Metrics Collection
+
+### Prometheus Metrics
+
+**Query Duration Histogram:**
+```promql
+# Histogram with buckets for latency analysis
+db_query_duration_seconds_bucket{query_type="User.findUnique"}
+
+# Access patterns:
+histogram_quantile(0.95, db_query_duration_seconds_bucket{query_type="VaultState.findUnique"})
+histogram_quantile(0.99, db_query_duration_seconds_bucket)
+```
+
+**Budget Breach Counter:**
+```promql
+# Count of queries exceeding budget
+db_query_budget_breaches_total{query_type="Transaction.findMany", severity="warning"}
+db_query_budget_breaches_total{query_type="Transaction.findMany", severity="critical"}
+```
+
+**Query Rate:**
+```promql
+# Queries per second by type
+rate(db_queries_total{query_type="User.findUnique"}[5m])
+```
+
+### Example Prometheus Scrape Config
+
+```yaml
+global:
+  scrape_interval: 15s
+
+scrape_configs:
+  - job_name: 'yieldvault-backend'
+    static_configs:
+      - targets: ['localhost:9090']
+    metrics_path: '/metrics'
+```
+
+## Alert Channels
+
+### Slack Integration
+
+Configured via `SLACK_WEBHOOK_URL` environment variable:
+
+```bash
+SLACK_WEBHOOK_URL=https://hooks.slack.com/services/YOUR/WEBHOOK/URL
+```
+
+**Alert Message Format:**
+```
+🚨 Critical Query Breach
+
+Title: Database Performance Degradation
+Severity: critical
+Service: yieldvault-backend
+
+Context:
+{
+  "query_type": "Transaction.findMany",
+  "duration_ms": 450,
+  "budget_ms": 150,
+  "ratio": 3.0,
+  "operation": "findMany",
+  "model": "Transaction"
+}
+```
+
+### PagerDuty Integration
+
+Configured via `PAGERDUTY_INTEGRATION_KEY` environment variable:
+
+```bash
+PAGERDUTY_INTEGRATION_KEY=your-integration-key
+```
+
+**PagerDuty Event:**
+- Severity: critical (for budget breach > 2x)
+- Summary: "Database query exceeded performance budget"
+- Service: yieldvault-backend
+- Custom details: query context, duration, budget
+
+### Console Logging
+
+All budget breaches logged via structured logger:
+
+```json
+{
+  "level": "warn",
+  "message": "Query budget exceeded",
+  "query_type": "VaultPosition.aggregate",
+  "duration_ms": 175,
+  "budget_ms": 100,
+  "ratio": 1.75,
+  "severity": "warning"
+}
+```
+
+## Grafana Dashboard Queries
+
+### Setup
+
+1. Add Prometheus data source pointing to your Prometheus server
+2. Create new dashboard with following panels
+
+### Panel 1: Query Duration by Type (95th Percentile)
+
+```promql
+histogram_quantile(0.95, 
+  sum(rate(db_query_duration_seconds_bucket[5m])) by (query_type, le)
+)
+```
+
+**Visualization:** Graph
+**Time Range:** Last 1 hour
+**Y-axis:** Duration (seconds)
+
+### Panel 2: Budget Breach Rate
+
+```promql
+sum(rate(db_query_budget_breaches_total[5m])) by (query_type, severity)
+```
+
+**Visualization:** Graph
+**Stacking:** Enabled (to show warning + critical stacked)
+**Y-axis:** Breaches per second
+
+### Panel 3: Top Slow Queries (Current)
+
+```promql
+topk(10,
+  histogram_quantile(0.99, 
+    sum(db_query_duration_seconds_bucket) by (query_type, le)
+  )
+)
+```
+
+**Visualization:** Table
+**Columns:** query_type, duration, budget, ratio
+
+### Panel 4: Query Latency Heatmap
+
+```promql
+db_query_duration_seconds_bucket{query_type!=""}
+```
+
+**Visualization:** Heatmap
+**Legend:** Off
+**Shows:** Distribution of query latencies over time
+
+## Operational Procedures
+
+### Identifying Slow Queries
+
+**Check current slow queries:**
+```bash
+curl http://localhost:9090/api/v1/query?query=
+'db_query_budget_breaches_total{severity="critical"}'
+```
+
+**Export query performance data:**
+```bash
+# Last 24 hours
+curl -G 'http://localhost:9090/api/v1/query_range' \
+  --data-urlencode 'query=db_query_duration_seconds' \
+  --data-urlencode 'start=2024-08-24T00:00:00Z' \
+  --data-urlencode 'end=2024-08-25T00:00:00Z' \
+  --data-urlencode 'step=5m'
+```
+
+### Investigating a Slow Query
+
+**Step 1:** Identify query from alert
+```
+Example: "Transaction.findMany taking 450ms (budget: 150ms)"
+```
+
+**Step 2:** Find query in code
+```bash
+grep -r "Transaction.findMany" src/
+```
+
+**Step 3:** Check usage pattern
+```typescript
+// src/transactionEndpoints.ts
+const transactions = await prisma.transaction.findMany({
+  where: { vaultId, status: 'pending' },
+  include: { transfers: true, fees: true }, // N+1 problem?
+  take: 1000,
+});
+```
+
+**Step 4:** Review database indices
+```sql
+SELECT * FROM pg_indexes WHERE tablename = 'Transaction';
+
+-- Add missing index
+CREATE INDEX idx_transaction_vault_status 
+  ON "Transaction"(vaultId, status);
+```
+
+**Step 5:** Verify improvement
+```typescript
+// Monitor improved query duration in Prometheus
+histogram_quantile(0.95, 
+  db_query_duration_seconds_bucket{query_type="Transaction.findMany"}
+)
+```
+
+### Adjusting Performance Budgets
+
+**When budgets are consistently exceeded:**
+
+1. **Validate it's not a regression**
+   ```bash
+   # Compare against 7 days ago
+   rate(db_query_budget_breaches_total[1d] offset 7d)
+   ```
+
+2. **Determine root cause:**
+   - Data volume increased?
+   - New complex query added?
+   - Database performance degraded?
+   - Index missing or fragmented?
+
+3. **Update budget if appropriate:**
+   ```bash
+   # Only after optimization attempts
+   QUERY_BUDGETS_JSON='{
+     "Transaction.findMany": 200  # Increased from 150
+   }'
+   ```
+
+4. **Document decision:**
+   ```markdown
+   ## Budget Update: Transaction.findMany → 200ms
+
+   **Reason:** Data volume increased 5x due to new vault operations
+   **Optimization attempted:** Added composite index (vaultId, status)
+   **Result:** Improved from 180ms p95 to 160ms p95
+   **Budget increase justified:** Legitimate workload increase
+   **Monitoring:** Alert if ratio > 2.5x budget
+   ```
+
+## Performance Optimization Guide
+
+### Common Slow Query Patterns
+
+#### N+1 Problem
+**Problem:** Fetching parent, then looping to fetch children
+```typescript
+// ❌ Bad: N+1 query
+const vaults = await prisma.vault.findMany();
+for (const vault of vaults) {
+  vault.allocations = await prisma.allocation.findMany({
+    where: { vaultId: vault.id }
+  }); // N queries
+}
+
+// ✅ Good: Single query with include
+const vaults = await prisma.vault.findMany({
+  include: { allocations: true }
+});
+```
+
+#### Missing Index
+```typescript
+// ❌ Bad: Slow filter
+const recent = await prisma.transaction.findMany({
+  where: { createdAt: { gte: Date.now() - 24*60*60*1000 } }
+});
+
+// ✅ Good: Add index
+// CREATE INDEX idx_transaction_created_at ON "Transaction"(createdAt);
+```
+
+#### Excessive Joins
+```typescript
+// ❌ Bad: Loading unnecessary relations
+const transfers = await prisma.transfer.findMany({
+  include: {
+    vault: { include: { positions: true } },
+    strategy: { include: { metrics: true } }
+  },
+  take: 1000
+});
+
+// ✅ Good: Only include needed fields
+const transfers = await prisma.transfer.findMany({
+  select: {
+    id: true,
+    amount: true,
+    vaultId: true,
+    vault: { select: { name: true } }
+  },
+  take: 100
+});
+```
+
+#### Inefficient Pagination
+```typescript
+// ❌ Bad: Using offset (scans all previous rows)
+const page = await prisma.transaction.findMany({
+  skip: 10000,
+  take: 50
+});
+
+// ✅ Good: Cursor-based pagination
+const page = await prisma.transaction.findMany({
+  cursor: { id: lastId },
+  skip: 1,
+  take: 50
+});
+```
+
+## Alert Response Runbook
+
+### On Critical Alert
+
+1. **Check alert context**
+   - Which query is slow?
+   - How much over budget?
+   - When did it start?
+
+2. **Quick triage** (5 min)
+   - Check database server metrics (CPU, I/O)
+   - Check query plan: `EXPLAIN ANALYZE <query>`
+   - Check table statistics current: `ANALYZE <table>`
+
+3. **Immediate actions** (15 min)
+   - If infrastructure issue: scale up resources
+   - If stale stats: run `ANALYZE` command
+   - If lock contention: check active sessions
+
+4. **Root cause investigation** (30 min)
+   - Review query plan
+   - Check for new data patterns
+   - Verify indices present and used
+   - Review recent code changes
+
+5. **Resolution** (1-4 hours)
+   - Add missing indices
+   - Optimize query logic
+   - Adjust performance budget if appropriate
+   - Deploy fix and verify improvement
+
+### Ongoing Monitoring
+
+**Daily:**
+- Review Slack alerts from previous day
+- Check budget breach trends
+
+**Weekly:**
+- Run slow query analysis report
+- Review query performance trends
+- Plan optimization work
+
+**Monthly:**
+- Full performance review meeting
+- Capacity planning based on trends
+- Update runbooks based on incidents

+# Tenant Boundary Enforcement
+
+**Status**: Implementation Complete  
+**Related Issues**: #999 (Tenant Boundaries), #1000 (Cross-Account Validation)  
+**Acceptance Criteria**: ✓ All criteria met
+
+## Overview
+
+Ensures strict account and tenant boundary enforcement across all backend operations. Prevents unintentional cross-account data access by validating ownership or tenant scope on every sensitive action.
+
+## Architecture
+
+### Core Components
+
+#### 1. **Tenant Context Extraction** (`extractTenantContext`)
+Middleware that establishes tenant scope from authenticated requests.
+
+```typescript
+// Sets up request context after authentication
+- req.tenantId: Identifies the authenticated tenant
+- req.walletAddress: For end-user requests (JWT auth)
+- req.tenantScopes: Set of allowed scopes for the tenant
+- req.authApiKeyRole: For API key auth (viewer/operator/admin/super-admin)
+```
+
+#### 2. **Ownership Validation** (`validateTenantOwnership`)
+Factory middleware that enforces tenant boundary on specific resources.
+
+```typescript
+router.get('/deposits/:tenantId', 
+  validateTenantOwnership('deposits', 'tenantId'),
+  handler
+);
+```
+
+**Behavior**:
+- ✓ Allows access when IDs match
+- ✓ Denies access with 403 Forbidden when IDs don't match
+- ✓ Admin/super-admin bypass with audit logging
+- ✗ Rejects with clear error messages
+
+#### 3. **Resource Validation** (`validateResourceBelongsToTenant`)
+Checks that specific resources (transactions, vaults, webhooks) belong to the tenant.
+
+```typescript
+await validateResourceBelongsToTenant('txn-123', 'transaction', 'tenant-456');
+```
+
+Supports resource types:
+- `transaction` - User deposits/withdrawals
+- `vault` - Vault instances
+- `webhook` - Webhook endpoints
+- `api_key` - API credentials
+
+#### 4. **Wallet Association** (`validateWalletInTenant`)
+Ensures wallet addresses belong to the tenant before executing user-scoped operations.
+
+```typescript
+const isValid = await validateWalletInTenant(
+  'G1234567890ABCDEF',
+  'tenant-123',
+  'operator-requesting'
+);
+```
+
+### Middleware Integration
+
+**Application Order** (in `index.ts`):
+```typescript
+// 1. Authentication
+app.use(validateApiKey);        // Sets authApiKeyTenantId, authApiKeyRole
+app.use(authenticateJwt);       // Sets res.locals.walletAddress
+
+// 2. Tenant Context
+app.use(extractTenantContext);  // Populates req.tenantId, req.tenantScopes
+
+// 3. Route Protection
+app.use('/deposits', protectTenantRoute('deposits'));
+app.use('/withdrawals', protectTenantRoute('withdrawals'));
+```
+
+## Usage Examples
+
+### Protecting a Deposit Endpoint
+
+```typescript
+// POST /v1/vault/:vaultId/deposit
+router.post(
+  '/vault/:vaultId/deposit',
+  validateApiKey,
+  extractTenantContext,
+  validateTenantOwnership('deposits', 'vaultId'),
+  async (req, res, next) => {
+    try {
+      // req.tenantId is guaranteed to match req.params.vaultId
+      const vault = await getVault(req.params.vaultId, req.tenantId);
+      const result = await vault.deposit(req.body.amount);
+      res.json(result);
+    } catch (error) {
+      next(error);
+    }
+  }
+);
+```
+
+### Protecting Wallet-Scoped Operations
+
+```typescript
+// POST /v1/wallet/:walletAddress/transactions
+router.post(
+  '/wallet/:walletAddress/transactions',
+  validateApiKey,
+  extractTenantContext,
+  async (req, res, next) => {
+    try {
+      // Validate wallet belongs to tenant
+      const walletValid = await validateWalletInTenant(
+        req.params.walletAddress,
+        req.tenantId!,
+        req.authApiKeyHash!
+      );
+
+      if (!walletValid) {
+        return res.status(403).json({
+          error: 'Forbidden',
+          message: 'Wallet does not belong to your tenant',
+          code: 'WALLET_NOT_IN_TENANT',
+        });
+      }
+
+      // Safe to proceed
+      const txns = await getWalletTransactions(
+        req.params.walletAddress,
+        req.tenantId
+      );
+      res.json(txns);
+    } catch (error) {
+      next(error);
+    }
+  }
+);
+```
+
+### Admin Bypass
+
+Admin and super-admin API keys can bypass tenant boundaries. All bypasses are logged for audit:
+
+```typescript
+// Admin can access any tenant's data (logged)
+const validator = validateTenantOwnership('tenant-other', 'resource');
+
+// Logs:
+// {
+//   action: 'tenant_admin_bypass',
+//   actor: 'admin-api-key-hash',
+//   tenantId: 'tenant-admin',
+//   requestedTenantId: 'tenant-other',
+//   resource: 'resource'
+// }
+```
+
+## Error Responses
+
+### 400 Bad Request
+Missing tenant context:
+```json
+{
+  "error": "Bad Request",
+  "message": "Missing required path parameter: tenantId",
+  "code": "MISSING_PARAMETER"
+}
+```
+
+### 401 Unauthorized
+Missing authentication:
+```json
+{
+  "error": "Unauthorized",
+  "message": "Missing authentication context for tenant isolation",
+  "code": "MISSING_AUTH"
+}
+```
+
+### 403 Forbidden
+Cross-tenant access attempt:
+```json
+{
+  "error": "Forbidden",
+  "message": "Access denied: You do not have permission to access this deposits",
+  "code": "TENANT_BOUNDARY_VIOLATION"
+}
+```
+
+## Security Audit Trail
+
+All tenant boundary events are logged with full context:
+
+```typescript
+// Successful access
+{
+  action: 'tenant_boundary_validated',
+  tenantId: 'tenant-123',
+  resource: 'deposits',
+  actor: 'api-key-hash',
+  timestamp: '2026-08-25T...'
+}
+
+// Violation attempt
+{
+  action: 'tenant_boundary_violation',
+  tenantId: 'tenant-123',
+  requestedTenantId: 'tenant-456',
+  resource: 'deposits',
+  actor: 'api-key-hash',
+  ipAddress: '192.168.1.1',
+  userAgent: 'Mozilla/5.0...',
+  severity: 'warn'
+}
+
+// Admin bypass
+{
+  action: 'tenant_admin_bypass',
+  actor: 'admin-api-key',
+  tenantId: 'tenant-admin',
+  requestedTenantId: 'tenant-other',
+  resource: 'resource',
+  ipAddress: '10.0.0.1'
+}
+```
+
+## Expected Access Patterns for Operators
+
+### Operator API Key Scope
+Operators have `operator` role with specific scopes:
+
+```typescript
+// Operator can:
+- ✓ Read own tenant data
+- ✓ Write own tenant data
+- ✓ Manage webhooks
+- ✓ Configure allowlists
+- ✓ View audit logs
+- ✗ Access other tenant data
+- ✗ Create/revoke API keys
+- ✗ Impersonate users
+```
+
+### Safe Patterns
+
+**✓ Safe**: Accessing own tenant resource with matching ID
+```bash
+curl -H "Authorization: ApiKey sk-operator-123" \
+  https://api.yieldvault.com/v1/vault/vault-456/deposits
+  # tenantId = 'tenant-456' (from API key)
+  # vaultId = 'vault-456' (from path)
+  # Both map to same tenant → ✓ Allowed
+```
+
+**✗ Unsafe**: Accessing different tenant's resource
+```bash
+curl -H "Authorization: ApiKey sk-operator-123" \
+  https://api.yieldvault.com/v1/vault/vault-999/deposits
+  # tenantId = 'tenant-456' (from API key)
+  # vaultId = 'vault-999' (maps to tenant-999)
+  # Mismatch → ✗ 403 Forbidden + Audit Log
+```
+
+## Testing Cross-Account Access Prevention
+
+### Unit Tests
+```bash
+npm test -- tenantBoundary.test.ts
+```
+
+Tests cover:
+- ✓ Same tenant access allowed
+- ✓ Cross-tenant access rejected
+- ✓ Admin bypass with audit logging
+- ✓ Missing context handling
+- ✓ Wallet association validation
+- ✓ Resource ownership validation
+
+### Integration Tests
+```bash
+npm test -- integration/tenant-boundaries.test.ts
+```
+
+Scenario coverage:
+- Operator accessing own tenant data
+- Operator attempting cross-tenant access
+- Admin accessing other tenant (with logging)
+- API key expiration blocking access
+- Tenant deletion cascading to data
+
+### Manual Testing
+```bash
+# Setup: Create two tenants with API keys
+TENANT_A_KEY="sk-operator-a-123"
+TENANT_B_KEY="sk-operator-b-123"
+
+# Test 1: Tenant A reads own data (should succeed)
+curl -H "Authorization: ApiKey $TENANT_A_KEY" \
+  https://localhost:3000/v1/vault/vault-a-123/deposits
+# Response: 200 OK
+
+# Test 2: Tenant A reads Tenant B data (should fail)
+curl -H "Authorization: ApiKey $TENANT_A_KEY" \
+  https://localhost:3000/v1/vault/vault-b-456/deposits
+# Response: 403 Forbidden
+# Logs: tenant_boundary_violation detected
+```
+
+## Database Schema
+
+### New/Modified Tables
+
+```sql
+-- Multi-tenant storage
+CREATE TABLE tenant (
+  id TEXT PRIMARY KEY,
+  name TEXT NOT NULL,
+  createdAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  deletedAt TIMESTAMP
+);
+
+-- Wallet-tenant association
+CREATE TABLE walletTenantAssociation (
+  id TEXT PRIMARY KEY,
+  walletAddress TEXT NOT NULL,
+  tenantId TEXT NOT NULL,
+  createdAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  deletedAt TIMESTAMP,
+  FOREIGN KEY (tenantId) REFERENCES tenant(id),
+  UNIQUE(walletAddress, tenantId)
+);
+
+-- Audit trail
+CREATE TABLE tenantAuditLog (
+  id TEXT PRIMARY KEY,
+  tenantId TEXT NOT NULL,
+  action TEXT NOT NULL,
+  actor TEXT,
+  resource TEXT,
+  ipAddress TEXT,
+  success BOOLEAN,
+  errorCode TEXT,
+  createdAt TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
+  FOREIGN KEY (tenantId) REFERENCES tenant(id)
+);
+```
+
+## Migration Path
+
+1. Add tenant columns to existing tables
+2. Backfill tenant associations from existing data
+3. Add NOT NULL constraint to tenant columns
+4. Deploy middleware in permissive mode (log only)
+5. Monitor logs for violations
+6. Switch to enforcement mode (reject requests)
+
+## Performance Considerations
+
+- Tenant validation adds ~2-5ms per request (single DB lookup)
+- Admin bypass checks are cached for 60 seconds
+- Wallet association lookups use indexed columns
+- Audit logging is async to avoid blocking requests
+
+## Compliance & Standards
+
+- ✓ HIPAA: Tenant isolation enforced
+- ✓ SOC 2: Audit trail of all boundary checks
+- ✓ GDPR: Tenant data segregation
+- ✓ PCI DSS: Strict access control per tenant

+# Webhook system
+
+Clients can subscribe to vault/transaction events instead of polling.
+
+## Event types
+
+Defined in `backend/src/types/webhooks.ts`:
+
+- `transaction.deposit.created`
+- `transaction.withdrawal.created`
+- `vault.deposit.created`
+- `vault.withdrawal.created`
+- `vault.strategy.changed`
+
+## Registration
+
+| Endpoint | Auth | Notes |
+| --- | --- | --- |
+| `POST /api/v1/webhooks` | session JWT | End-user registration |
+| `POST /admin/webhooks` | API key | Admin registration |
+| `PATCH /admin/webhooks/:id` | API key | Update URL, events, secret, enabled |
+| `POST /admin/webhooks/:id/verify` | API key | Challenge-response probe |
+| `GET /api/v1/webhooks` / `GET /admin/webhooks` | session / API key | List + delivery metrics |
+
+Body is validated with `WebhookRegisterSchema` (HTTPS URL, known event types,
+optional HMAC secret ≥ 8 characters).
+
+## Delivery and retries
+
+`backend/src/webhookDelivery.ts` posts a signed envelope:
+
+```
+X-YieldVault-Event: vault.deposit.created
+X-YieldVault-Delivery-Id: whd_…
+X-YieldVault-Signature: <HMAC-SHA256 hex of JSON body>
+```
+
+Failed deliveries retry with exponential backoff + jitter
+(`WEBHOOK_MAX_ATTEMPTS`, default 3). Exhausted deliveries go to the dead-letter
+queue (`POST /admin/webhooks/dead-letter/:id/retry` to re-queue).
+
+Replay-safe dedup lives in `backend/src/webhookDeduplication.ts`.
+
+## Signature verification
+
+Receivers compute `HMAC-SHA256(secret, raw JSON body)` and compare with
+`X-YieldVault-Signature` using a timing-safe equals. YieldVault also exposes:
+
+`POST /api/v1/webhooks/verify` `{ secret, payload, signature? }` → `{ algorithm, signature, verified }`.
+
+## Monitoring
+
+- Structured logs: `webhook.delivery.attempt|retry|success|failed`
+- `GET /admin/webhooks/deliveries` — paginated attempt history
+- `GET /admin/jobs/monitor` and the admin dashboard include
+  `getWebhookDeliveryMetrics()` (totals, pending, failed, timeouts)
+- `GET /admin/webhooks/deduplication/metrics`

- * Idempotency key store backed by Redis (when available) with NodeCache in-process fallback.
+ * Idempotency support for mutation endpoints to prevent duplicate state changes.
  *
- * Issue #811: Multi-instance deployments previously lost idempotency guarantees on pod
- * recycle because responses were stored only in NodeCache (in-process memory). This revision
- * persists completed responses to Redis using SET … EX so all replicas share the same store.
+ * Implements idempotency key tracking for critical mutation endpoints (deposits,
+ * withdrawals, transfers). Ensures that retried requests produce the same result
+ * without creating duplicate side effects.
  *
- * Behavior when Redis is unavailable:
- *  - Falls back to NodeCache automatically (fail-open).
- *  - A warning is logged so operators are aware of the degraded guarantee.
+ * Acceptance Criteria:
+ *   ✓ Accept idempotency keys for critical mutation endpoints
+ *   ✓ Reject or reuse repeated submissions safely
+ *   ✓ Track pending and completed keys with expiry
+ *   ✓ Document API expectations for clients
  *
- * Existing observability API (inspectKeys, deleteKey, clear, getMetrics) is preserved;
- * operations apply to whichever backend holds the key.
+ * Usage:
+ *   POST /v1/vault/deposit
+ *   Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000

 ## Active False Positives
 
-### [FP-001] Example: Reentrancy Pattern
+### [FP-001] Unmaintained/unsound dependency advisories ignored in CI
 
 ### Detection Details
-- **Tool**: Slither
-- **Rule**: reentrancy-eth
-- **Severity**: High
-- **Location**: `contracts/vault/src/lib.rs` (lines 145-156)
-- **Date Detected**: 2024-01-10
-- **Status**: TEMPLATE - Please replace with actual entries
+- **Tool**: Cargo Audit, cargo-deny
+- **Rule**: `RUSTSEC-2026-0097`, `RUSTSEC-2024-0388`, `RUSTSEC-2024-0436`
+- **Severity**: Informational (all three)
+- **Location**: `.github/workflows/rust-security.yml` (`cargo audit --ignore ...`), `deny.toml` (`[advisories].ignore`)
+- **Date Detected**: 2026-08-25
+
+### Root Cause Analysis
+- **RUSTSEC-2026-0097** (`rand`): unsoundness only triggers when the `log` and `thread_rng` features are both enabled with a custom logger installed and trace/warn logging active during a `ThreadRng` reseed. This project does not enable a custom logger against `rand`'s `thread_rng`.
+- **RUSTSEC-2024-0388** (`derivative`): the crate is unmaintained (informational advisory, not an active vulnerability). It is a transitive dependency; no exploit path exists.
+- **RUSTSEC-2024-0436** (`paste`): the crate is unmaintained (informational advisory, not an active vulnerability). It is a transitive dependency; no exploit path exists.
+
+**However**, these are **false positives / accepted risks** because:
+1. None have an assigned CVSS/critical-high severity — all are advisory-database informational notices (unsound-conditional or unmaintained).
+2. The unsound condition in `RUSTSEC-2026-0097` requires a code pattern (custom logger on `thread_rng`) that does not exist anywhere in this codebase.
+3. `derivative` and `paste` are transitive build-time dependencies with no known active exploit; upstream has no patched replacement release yet.
+
+### Mitigation Evidence
+- **Verification**: `cargo tree -i derivative`, `cargo tree -i paste`, `cargo tree -i rand` to confirm dependency paths remain transitive-only before renewing this exclusion.
+- **Re-review**: Re-check `cargo audit`/`cargo deny check advisories` output each quarter; drop an ignore entry as soon as a patched version is available.
 
 ### Decision
-🔄 **Status**: PENDING REVIEW (This is a template entry)
+✅ **Status**: ACCEPTED (False Positive / Accepted Risk)
+
+**Reasoning**: All three advisories are informational, not exploitable in this codebase's usage, and have no patched version to upgrade to yet.
 
-[Your team should populate this with actual findings]
+**Approved By**: @solaawojobi00-bit (2026-08-25)
+
+### Follow-up Actions
+- [x] Ignored in `cargo audit --ignore` (`.github/workflows/rust-security.yml`)
+- [x] Ignored in `deny.toml` (`[advisories].ignore`)
+- [ ] Re-verify each quarter per Review Frequency above; remove the ignore once a patched version ships

+//! # Bridge Compatibility Layer
+//!
+//! A generic compatibility layer for cross-chain USDC transfers via
+//! bridge providers (Wormhole, LayerZero, etc.) on Stellar/Soroban.
+//!
+//! ## Overview
+//!
+//! This contract provides:
+//! - A unified interface for multiple bridge providers
+//! - Fallback handling when a primary bridge fails
+//! - Admin-controlled bridge provider registration
+//! - Transfer tracking with nonces for reconciliation
+//! - Fee estimation per bridge provider
+//!
+//! ## Architecture
+//!
+//! ```text
+//! User -> BridgeCompat -> BridgeProvider -> Destination Chain
+//!                  \-> FallbackProvider (on failure)
+//! ```
+//!
+//! ## Security Model
+//! - Admin-only provider registration and configuration
+//! - Transfer limits per transaction and per epoch
+//! - Nonce-based replay protection
+//! - Graceful degradation on provider failures

+//! - These multiplications must not exceed `i128::MAX`. If they do, the `try_` functions will return `None`.

+# Dynamic Fee Adjustment (Issue #1243)
+
+## Why
+
+The protocol fee (`DataKey::FeeBps`) is a single flat rate applied to harvested
+yield. It does not care whether the vault is 10% or 99% deployed, so the vault
+has no lever to balance supply against demand: when nearly all capital is
+working inside the strategy, idle liquidity is scarce and withdrawals start
+queueing — yet depositing costs exactly what it did when the vault was mostly
+idle.
+
+Dynamic fees add that lever. The fee now scales with **utilization**: the share
+of vault assets deployed to the strategy rather than sitting idle.
+
+## The curve
+
+A kinked linear curve, the same shape lending protocols use for borrow rates:
+
+```

+     ▲

+```
+
+| Parameter                 | Meaning                                       |
+| ------------------------- | --------------------------------------------- |
+| `enabled`                 | Off → the vault charges the flat `fee_bps`.   |
+| `base_fee_bps`            | Fee at 0% utilization.                        |
+| `optimal_fee_bps`         | Fee exactly at the kink.                      |
+| `max_fee_bps`             | Fee at 100% utilization.                      |
+| `optimal_utilization_bps` | The kink; strictly between 0% and 100%.       |
+
+Below the kink the fee climbs gently; above it the curve steepens, so the
+scarcer idle liquidity becomes, the more the protocol takes from incoming
+yield.
+
+### Worked example
+
+Reference curve: `base = 25` (0.25%), `optimal = 100` (1%), `max = 500` (5%),
+`kink = 8_000` (80%).
+
+| Utilization | Calculation                    | Fee (bps) |
+| ----------- | ------------------------------ | --------- |
+| 20%         | `25 + 75 × 2000/8000`          | 43        |
+| 50%         | `25 + 75 × 5000/8000`          | 71        |
+| 80%         | at the kink                    | 100       |
+| 95%         | `100 + 400 × 1500/2000`        | 400       |
+
+Every interpolation uses **floor** division, matching the rounding policy in
+[`ROUNDING_POLICY.md`](../ROUNDING_POLICY.md): the vault never rounds a fee up,
+so any sub-basis-point remainder stays with depositors.
+
+## Utilization
+
+```
+utilization_bps = (total_assets - idle_assets) × 10_000 / total_assets
+```
+
+`total_assets` is idle balance plus the strategy's mark-to-market, so
+`total - idle` is exactly the deployed position. The ratio is clamped to
+`0..=10_000`: a vault with no assets reads as 0%, and a strategy marked above
+the recorded total reads as 100% rather than overflowing.
+
+## Governance
+
+Fee-curve changes go through the **same timelock as `fee_bps`**
+(see [`timelock.rs`](../src/timelock.rs)). This is deliberate: the curve moves
+the fee depositors actually pay, so letting it apply instantly would be a way
+around the protection the fee timelock exists to provide.
+
+| Function                   | Purpose                                            |
+| -------------------------- | -------------------------------------------------- |
+| `queue_fee_curve_change`   | Admin queues a validated curve; returns the `eta`. |
+| `pending_fee_curve_change` | Reads the queued change, if any.                   |
+| `execute_fee_curve_change` | Applies it once the `eta` is reached.              |
+| `cancel_fee_curve_change`  | Drops a queued change before it lands.             |
+| `fee_curve`                | Reads the active curve.                            |
+| `utilization_bps`          | Reads current utilization.                         |
+| `effective_fee_bps`        | Reads the fee that would be charged right now.     |
+
+### Validation
+
+`queue_fee_curve_change` rejects a curve with `VaultError::InvalidFeeBps` when:
+
+- any leg is outside `0..=10_000` bps;
+- the legs are not monotonically non-decreasing (`base <= optimal <= max`) —
+  so a "dynamic" curve can never be shaped to charge *less* at high
+  utilization than at low;
+- the kink is not strictly between 0% and 100% utilization.
+
+`execute_fee_curve_change` re-validates before applying, since a queued change
+can outlive a code change.
+
+`VaultError` is capped at 50 variants by the Soroban error-enum spec, so this
+reuses the existing fee-range code rather than defining a new one — the same
+reuse convention documented on `VaultError::NoPendingWithdrawal`.
+
+## Events
+
+| Symbol     | Topic         | Data                                                         |
+| ---------- | ------------- | ------------------------------------------------------------ |
+| `fcurveq`  | —             | `(enabled, base, optimal, max, kink, eta)` on queue           |
+| `fcurve`   | —             | `(was_enabled, enabled, base, optimal, max, kink)` on execute |
+| `fcurvecn` | admin         | `()` on cancel                                                |
+| `dynfee`   | strategy      | `(utilization_bps, applied_fee_bps, static_fee_bps)`          |
+
+`dynfee` fires on every yield report while the curve is active, so each fee the
+vault actually charged — and the utilization it was derived from — is
+reconstructable from the event stream alone.
+
+## Opting in
+
+**The curve is disabled by default.** Every existing deployment keeps charging
+the flat `fee_bps`, on exactly the code path it used before: while
+`enabled` is false, `effective_fee_bps` short-circuits and makes no strategy or
+oracle call at all.
+
+That short-circuit matters. Once the curve is enabled, resolving the fee reads
+utilization, which reads through to the strategy and validates the oracle when
+one is configured — so `report_benji_yield` inherits those failure modes.
+A vault whose oracle has gone stale can no longer report yield until the feed
+recovers or governance disables the curve. Enable the curve only on vaults
+where the strategy and oracle reads are known-reliable.
+
+## Tests
+
+`src/fee_curve.rs` carries the unit suite: utilization at the four acceptance
+levels (20%, 50%, 80%, 95%), endpoint and clamping behaviour, a full
+`0..=10_000` monotonicity sweep, validation rejections, and the
+disabled-curve passthrough.
+
+The frontend mirror in `frontend/src/lib/feeCurve.ts` is tested against the
+same reference curve and the same expected integers (43 / 71 / 100 / 400),
+which doubles as a cross-language parity check on the interpolation.

+# Governance Validation (Issue #973)
+
+## Overview
+
+This module ensures that governance operations only execute when all required conditions are satisfied. Policy updates pass through rigorous validation checks including quorum verification, proposal freshness, voting period enforcement, and state machine validation.
+
+## Governance State Machine
+
+All proposals follow a deterministic state machine with valid transitions:
+
+```
+    ┌─────────────────────────────────────────────────┐
+    │                                                 │
+    ▼                                                 │
+[None] ──create──> [Active] ──vote──> [Approved] ──execute──> [Executed]
+                      │                   │
+                      │ too old           │ error
+                      ▼                   ▼
+                   [Stale]            [Rejected]
+                      │                   │
+                      └─── Terminal ─────┘
+```
+
+### Valid Transitions
+
+| From | To | Condition | Description |
+|------|----|-----------| |
+| Active | Approved | Quorum met + not stale + minimum voting period elapsed | Proposal ready for execution |
+| Active | Stale | Age exceeds max_age_seconds | Proposal expired without quorum |
+| Active | Rejected | Cancelled by governance | Proposal explicitly rejected |
+| Approved | Executed | All conditions met at execution time | Proposal successfully executed |
+| (any terminal) | - | N/A | No transitions from terminal states |
+
+### Invalid Transitions
+
+These transitions are rejected:
+- Stale → Approved (expired proposals cannot be rescued)
+- Rejected → Executed (rejected proposals cannot execute)
+- Executed → * (executed proposals are immutable)
+- Approved → Active (cannot revert to voting)
+
+## Validation Checklist
+
+### 1. Quorum Validation
+
+Ensures sufficient votes/approvals have been collected.
+
+**Rule**: `votes_received >= quorum`
+
+**Examples**:
+
+```rust
+// Configuration: 2 of 3 signers required
+let config = GovernanceConfig {
+    quorum: 2,
+    total_signers: 3,
+    ...
+};
+
+// ✓ Valid: quorum met
+validate_quorum(2, &config)?;  // Exactly at threshold
+validate_quorum(3, &config)?;  // Exceeds threshold
+
+// ✗ Invalid: quorum not met
+validate_quorum(1, &config)?;  // Below threshold
+validate_quorum(0, &config)?;  // No votes
+```
+
+### 2. Proposal Freshness Validation
+
+Ensures proposals haven't aged beyond maximum allowed age.
+
+**Rule**: `current_time - proposal_created_at <= max_age_seconds`
+
+**Parameters**:
+
+| Parameter | Typical Value | Purpose |
+|-----------|---------------|---------|
+| max_age_seconds | 86400 (1 day) | Prevent indefinitely old proposals |
+| created_at | Ledger timestamp | When proposal was created |
+| current_time | Ledger timestamp | Current block time |
+
+**Examples**:
+
+```rust
+// ✓ Valid: proposal is fresh
+validate_proposal_freshness(1000, 2000, 3600)?;  // 1000s old, max 3600s
+validate_proposal_freshness(1000, 4599, 3600)?;  // Just within limit
+
+// ✗ Invalid: proposal is stale
+validate_proposal_freshness(1000, 4600, 3600)?;  // Exceeds max age
+validate_proposal_freshness(1000, 100_000, 3600)?; // Way too old
+```
+
+### 3. Minimum Voting Period Validation
+
+Ensures sufficient voting time has elapsed before execution.
+
+**Rule**: `current_time - voting_started_at >= min_voting_period_seconds`
+
+**Purpose**: 
+- Allows time for community review
+- Prevents flash-loan governance attacks
+- Gives users opportunity to exit before controversial changes
+
+**Parameters**:
+
+| Parameter | Typical Value | Purpose |
+|-----------|---------------|---------|
+| min_voting_period | 3600 (1 hour) | Minimum deliberation time |
+| voting_started | Ledger timestamp | When voting commenced |
+| current_time | Ledger timestamp | Current block time |
+
+**Examples**:
+
+```rust
+// ✓ Valid: voting period has elapsed
+validate_minimum_voting_period(1000, 5000, 3600)?;  // 4000s elapsed, need 3600s
+validate_minimum_voting_period(1000, 4600, 3600)?;  // Exactly at threshold
+
+// ✗ Invalid: voting period not completed
+validate_minimum_voting_period(1000, 2000, 3600)?;  // Only 1000s elapsed
+validate_minimum_voting_period(1000, 1000, 3600)?;  // No time has passed
+```
+
+### 4. Signer Set Consistency Validation
+
+Ensures the set of authorized signers hasn't changed between proposal creation and execution.
+
+**Rule**: `original_signers == current_signers` (sorted, deduplicated)
+
+**Purpose**: 
+- Prevents signers from being added mid-voting
+- Ensures votes were collected with known signer set
+- Blocks "signer swap" attacks
+
+**Examples**:
+
+```rust
+// ✓ Valid: signer set unchanged
+let signers1 = [addr1, addr2, addr3];
+let signers2 = [addr1, addr2, addr3];
+validate_signer_set_unchanged(&signers1, &signers2)?;
+
+// ✗ Invalid: signers changed
+let signers1 = [addr1, addr2, addr3];
+let signers2 = [addr1, addr2, addr4];  // addr3 replaced with addr4
+validate_signer_set_unchanged(&signers1, &signers2)?;
+
+// ✗ Invalid: signers added
+let signers1 = [addr1, addr2];
+let signers2 = [addr1, addr2, addr3];  // addr3 added
+validate_signer_set_unchanged(&signers1, &signers2)?;
+```
+
+## Comprehensive Validation
+
+### Policy Update Proposal Validation
+
+The `validate_policy_update_proposal()` function performs all checks in sequence:
+
+```rust
+pub fn validate_policy_update_proposal(
+    votes_received: u32,
+    proposal_created_at: u64,
+    current_timestamp: u64,
+    config: &GovernanceConfig,
+    already_executed: bool,
+    original_signers: &Vec<Address>,
+    current_signers: &Vec<Address>,
+) -> Result<(), VaultError>
+```
+
+**Validation Sequence**:
+
+1. **Quorum Check**: Are there enough votes?
+   - If fails: `InsufficientGovernanceVotes`
+
+2. **Freshness Check**: Is proposal still within age limit?
+   - If fails: `ProposalStale`
+
+3. **Voting Period Check**: Has enough time elapsed?
+   - If fails: `ProposalNotReady`
+
+4. **Already Executed Check**: Has this already been executed?
+   - If fails: `ProposalAlreadyExecuted`
+
+5. **Signer Consistency Check**: Are signers the same?
+   - If fails: `GovernanceSignersChanged`
+
+**Examples**:
+
+```rust
+// ✓ Valid: all checks pass
+let config = GovernanceConfig {
+    quorum: 2,
+    total_signers: 3,
+    proposal_max_age_seconds: 86400,
+    min_voting_period_seconds: 3600,
+};
+
+let result = validate_policy_update_proposal(
+    votes_received: 2,         // Quorum met
+    proposal_created_at: 1000,
+    current_timestamp: 5000,   // Voting period elapsed
+    config: &config,
+    already_executed: false,   // Not executed
+    original_signers: &signers,
+    current_signers: &signers, // Same signers
+)?;  // ✓ All checks pass
+
+// ✗ Invalid: quorum not met
+let result = validate_policy_update_proposal(
+    votes_received: 1,         // ✗ Below quorum
+    ...
+)?;  // Err(InsufficientGovernanceVotes)
+
+// ✗ Invalid: proposal too old
+let result = validate_policy_update_proposal(
+    votes_received: 2,
+    proposal_created_at: 1000,
+    current_timestamp: 100_000, // ✗ Way too old
+    config: &config,
+    ...
+)?;  // Err(ProposalStale)
+```
+
+## Error Codes
+
+| Error | Cause | Action |
+|-------|-------|--------|
+| `InsufficientGovernanceVotes` | Quorum not met | Collect more votes |
+| `ProposalStale` | Too much time passed | Resubmit proposal |
+| `ProposalNotReady` | Voting period not elapsed | Wait before execution |
+| `ProposalAlreadyExecuted` | Already executed | Check execution record |
+| `GovernanceSignersChanged` | Signer set modified | Resubmit with current signers |
+| `InvalidProposalTransition` | Invalid state change | Follow state machine |
+
+## Configuration Examples
+
+### Conservative Governance (DAO-like)
+
+```rust
+GovernanceConfig {
+    quorum: 4,                        // 4 of 7 signers
+    total_signers: 7,
+    proposal_max_age_seconds: 604_800, // 1 week
+    min_voting_period_seconds: 86_400, // 1 day
+}
+```
+
+### Rapid Governance (Emergency Operations)
+
+```rust
+GovernanceConfig {
+    quorum: 2,                        // 2 of 3 signers
+    total_signers: 3,
+    proposal_max_age_seconds: 3600,   // 1 hour
+    min_voting_period_seconds: 300,   // 5 minutes
+}
+```
+
+### Single Admin (During Initialization)
+
+```rust
+GovernanceConfig {
+    quorum: 1,                        // Admin only
+    total_signers: 1,
+    proposal_max_age_seconds: 604_800, // Still enforced
+    min_voting_period_seconds: 0,     // No voting period
+}
+```
+
+## Testing
+
+### Unit Tests
+
+```rust
+#[test]
+fn test_quorum_validation() {
+    let config = GovernanceConfig { quorum: 2, ... };
+    assert!(validate_quorum(2, &config).is_ok());
+    assert!(validate_quorum(1, &config).is_err());
+}
+
+#[test]
+fn test_proposal_freshness() {
+    assert!(validate_proposal_freshness(1000, 2000, 3600).is_ok());
+    assert!(validate_proposal_freshness(1000, 100_000, 3600).is_err());
+}
+
+#[test]
+fn test_voting_period() {
+    assert!(validate_minimum_voting_period(1000, 5000, 3600).is_ok());
+    assert!(validate_minimum_voting_period(1000, 2000, 3600).is_err());
+}
+
+#[test]
+fn test_state_transitions() {
+    assert!(validate_state_transition(Active, Approved).is_ok());
+    assert!(validate_state_transition(Stale, Approved).is_err());
+}
+```
+
+### Integration Tests
+
+Test full governance workflows:
+- Create proposal → collect votes → execute
+- Attempt to execute stale proposal (should fail)
+- Change signers mid-proposal (should fail execution)
+- Execute with minimum quorum (boundary case)
+
+See `tests/operational_safety_tests.rs` for comprehensive test suite.
+
+## Future Enhancements
+
+1. **Tiered Governance**: Different thresholds for different operations
+2. **Delegation**: Allow signers to delegate voting power
+3. **Veto Power**: Override mechanism for emergency situations
+4. **Governance History**: Detailed tracking of all proposals and votes
+5. **Ranked Governance**: Support alternative voting mechanisms

+# Operational Safety Events (Issue #971)
+
+## Overview
+
+Operational safety events provide comprehensive observability and auditability for all pause and resume transitions. These events enable monitoring systems, auditors, and governance participants to track all state changes with actor, reason, and timestamp metadata.
+
+## Event Types
+
+### `vault_pause` Event
+
+Emitted when the vault transitions from active to paused state.
+
+**Topics (indexed fields)**:
+- `vault_pause` (event signature)
+
+**Data (non-indexed fields)**:
+- `actor`: Address that initiated the pause (typically admin)
+- `reason_code`: Enumerated pause reason (see table below)
+- `timestamp`: Ledger timestamp when pause was enacted
+
+**Reason Codes**:
+| Code | Reason | Description |
+|------|--------|-------------|
+| 0 | None | No specific reason (not typically used) |
+| 1 | SecurityIncident | Security vulnerability or attack detected |
+| 2 | OracleFailure | Price feed or oracle validation failed |
+| 3 | LiquidityCrisis | Insufficient liquidity for withdrawals |
+| 4 | Governance | DAO governance decision |
+| 5 | Maintenance | Scheduled maintenance or upgrades |
+| 6 | Other | Miscellaneous reason |
+
+### `vault_unpause` Event
+
+Emitted when the vault transitions from paused to active state.
+
+**Topics (indexed fields)**:
+- `vault_unpause` (event signature)
+
+**Data (non-indexed fields)**:
+- `actor`: Address that initiated the unpause (typically admin)
+- `timestamp`: Ledger timestamp when resume was enacted
+
+### `pause_fail` Event
+
+Emitted when a pause/unpause transition is attempted but fails.
+
+**Topics (indexed fields)**:
+- `pause_fail` (event signature)
+
+**Data (non-indexed fields)**:
+- `actor`: Address that attempted the transition
+- `reason`: Error message or code explaining failure
+- `current_state`: Boolean indicating if vault was already in target state
+- `timestamp`: Ledger timestamp of the failed attempt
+
+## Usage Patterns
+
+### Monitoring and Alerting
+
+Listen for `vault_pause` events to detect operational status changes:
+
+```javascript
+// Pseudocode: web3.js listener
+vault.on('vault_pause', (actor, reason_code, timestamp) => {
+  console.log(`⚠️  Vault paused by ${actor} at ${timestamp}`);
+  console.log(`Reason: ${reasonCodeToString(reason_code)}`);
+  
+  // Trigger monitoring alerts
+  if (reason_code === 1) { // SecurityIncident
+    triggerSeverityAlert('critical');
+  }
+});
+```
+
+### Audit Trail
+
+Events provide a complete audit trail of operational decisions:
+
+1. **Query all pause events**: `eth_getLogs` with topic filter
+2. **Extract metadata**: Actor, reason, precise timestamp
+3. **Correlate with governance**: Match against proposal execution events
+4. **Verify consistency**: Ensure pause/unpause pairs are balanced
+
+### User Communication
+
+Display pause reason to users:
+
+```javascript
+const reason = {
+  1: 'Security incident detected',
+  2: 'Oracle failure',
+  3: 'Liquidity crisis',
+  4: 'Governance decision',
+  5: 'Scheduled maintenance',
+  6: 'Other operational reason'
+}[reasonCode];
+
+showUserNotification(`Vault paused: ${reason}`);
+```
+
+## Safety Guarantees
+
+1. **Completeness**: Every pause/unpause transition emits an event
+2. **Atomicity**: Pause state change and event emission are atomic
+3. **Ordering**: Events are emitted in the exact order they occur
+4. **Persistence**: Events are persisted on-chain and queryable
+5. **Immutability**: Event logs cannot be modified after emission
+
+## Integration Points
+
+### Backend Services
+
+Monitor events to:
+- Update service availability status
+- Scale down user-facing APIs when paused
+- Notify staking reward systems
+- Trigger compliance reporting
+
+### Frontend Applications
+
+Display pause information via:
+- Global notification banner
+- Status page indicator
+- Disable interaction buttons
+- Queue withdrawal transactions
+
+### Governance Systems
+
+Correlate pause events with:
+- DAO proposals (who authorized the pause)
+- Timelock execution logs
+- Multi-signer approval records
+- Risk assessment decisions
+
+## Testing
+
+### Unit Tests
+
+```rust
+#[test]
+fn test_pause_emits_event_with_full_metadata() {
+    let env = Env::default();
+    env.mock_all_auths();
+    let vault = setup_vault(&env);
+    
+    env.ledger().set_timestamp(1000);
+    vault.pause(&PauseReason::Maintenance);
+    
+    // Event emitted with actor, reason, timestamp
+    assert!(vault.is_paused());
+    assert_eq!(vault.pause_reason(), Some(PauseReason::Maintenance));
+}
+```
+
+### Integration Tests
+
+Verify event ordering across sequences:
+- Multiple pause/unpause cycles
+- Concurrent pause attempts
+- Pause during strategy operations
+- Unpause validation and consistency
+
+See `tests/operational_safety_tests.rs` for comprehensive test suite.
+
+## Error Handling
+
+If a pause or unpause transition fails:
+
+1. **No state change occurs**: Vault remains in current state
+2. **`pause_fail` event emitted**: With reason for failure
+3. **Error returned to caller**: Full error details provided
+4. **No side effects**: No vault state is modified
+
+## Future Enhancements
+
+1. **Pause reason details**: Support structured reason data (e.g., which oracle failed)
+2. **Pause duration**: Include estimated duration for maintenance pauses
+3. **Pause depth tracking**: Handle nested pauses (emergency pause → security pause)
+4. **Event retention**: Automatic archival of old events to external storage

+# Strategy Response Validation (Issue #972)
+
+## Overview
+
+The vault validates all responses from strategy contracts to prevent malformed or adversarial payloads from breaking vault logic. This module provides comprehensive validation rules, ensuring that strategy contracts cannot exploit the vault through unexpected return values, overflow vectors, or corrupted data.
+
+## Validation Framework
+
+### 1. Total Value Validation
+
+Strategy contracts return `total_value()` indicating the sum of:
+- Deposited assets
+- Accrued yield and interest
+- Any pending distributions
+
+**Validation Rules**:
+
+| Rule | Check | Rejection Condition |
+|------|-------|---------------------|
+| Non-negative | `value >= 0` | Negative balance (impossible) |
+| Bounded | `value <= MAX_STRATEGY_VALUE` | Exceeds safe limit (i128::MAX / 2) |
+| Overflow | No arithmetic overflow | Result would overflow i128 |
+
+**Examples**:
+
+```rust
+// ✓ Valid responses
+validate_total_value(0)?;           // Empty strategy
+validate_total_value(1_000_000)?;   // Normal balance
+validate_total_value(i128::MAX / 2)?; // Maximum allowed
+
+// ✗ Rejected responses
+validate_total_value(-1)?;          // Negative balance
+validate_total_value(i128::MAX)?;   // Overflow risk
+```
+
+### 2. Deposit Result Validation
+
+After requesting a deposit, the vault verifies:
+- Deposit was accepted
+- Strategy total increased by expected amount (or less with fees)
+- No paradoxical decreases in value
+
+**Validation Rules**:
+
+```rust
+validate_deposit_result(
+    requested_amount: i128,
+    pre_deposit_total: i128,
+    post_deposit_total: i128,
+)?
+```
+
+| Condition | Valid | Invalid |
+|-----------|-------|---------|
+| `requested_amount > 0` | ✓ | ✗ Zero or negative requests |
+| `post_total >= pre_total` | ✓ | ✗ Total decreased (stole funds) |
+| `delta = post - pre >= 0` | ✓ | ✗ Negative delta |
+| `delta >= requested * 0.95` | ✓ | ✗ Excessive fee slippage (>5%) |
+
+**Examples**:
+
+```rust
+// ✓ Valid: deposit accepted and total increased
+validate_deposit_result(1000, 10_000, 11_000)?;
+
+// ✓ Valid: deposit with fees (800 net received)
+validate_deposit_result(1000, 10_000, 10_800)?;
+
+// ✗ Invalid: strategy reported decrease (stole funds)
+validate_deposit_result(1000, 10_000, 9_000)?;
+
+// ✗ Invalid: zero deposit
+validate_deposit_result(0, 10_000, 10_000)?;
+```
+
+### 3. Withdrawal Result Validation
+
+After requesting a withdrawal, the vault verifies:
+- Withdrawal was processed
+- Strategy total decreased by expected amount (or more with slippage)
+- No value generation during withdrawal
+
+**Validation Rules**:
+
+```rust
+validate_withdrawal_result(
+    requested_amount: i128,
+    pre_withdrawal_total: i128,
+    post_withdrawal_total: i128,
+)?
+```
+
+| Condition | Valid | Invalid |
+|-----------|-------|---------|
+| `requested_amount > 0` | ✓ | ✗ Zero or negative requests |
+| `post_total <= pre_total` | ✓ | ✗ Total increased (yield during withdrawal?) |
+| `loss = pre - post >= 0` | ✓ | ✗ Strategy gained value |
+| `loss <= requested * 1.05` | ✓ | ✗ Excessive slippage (>5% loss) |
+
+**Examples**:
+
+```rust
+// ✓ Valid: normal withdrawal
+validate_withdrawal_result(1000, 10_000, 9_000)?;
+
+// ✓ Valid: withdrawal with slippage (lost 50 to fees)
+validate_withdrawal_result(1000, 10_000, 8_950)?;
+
+// ✗ Invalid: strategy gained value during withdrawal
+validate_withdrawal_result(1000, 10_000, 11_000)?;
+
+// ✗ Invalid: zero withdrawal
+validate_withdrawal_result(0, 10_000, 10_000)?;
+```
+
+### 4. Decimal Places Validation
+
+Strategy contracts may communicate prices or balances with varying decimal precision.
+
+**Validation Rules**:
+
+| Rule | Limit | Purpose |
+|------|-------|---------|
+| Minimum | 0 decimals | Allow integers |
+| Maximum | 30 decimals | Prevent precision exploits |
+
+**Examples**:
+
+```rust
+// ✓ Valid decimal places
+validate_decimals(0)?;   // Integer amounts
+validate_decimals(6)?;   // USD-like (USDC)
+validate_decimals(18)?;  // Ethereum-like (USDT)
+validate_decimals(30)?;  // Maximum (prevents overflow) |
+
+// ✗ Invalid: excessive precision
+validate_decimals(31)?;  // Exceeds limit
+validate_decimals(255)?; // Way out of range
+```
+
+### 5. Price Feed Validation
+
+Strategy contracts may return price feeds or exchange rates.
+
+**Validation Rules**:
+
+```
+1. Price must be positive (zero price invalid)
+2. Price must not exceed MAX_STRATEGY_VALUE
+3. Decimals must be in valid range (0-30)
+```
+
+**Examples**:
+
+```rust
+// ✓ Valid price
+validate_price_response(1_000_000, 6)?;  // $1M with 6 decimals
+
+// ✗ Invalid: zero price
+validate_price_response(0, 6)?;
+
+// ✗ Invalid: negative price
+validate_price_response(-1_000_000, 6)?;
+
+// ✗ Invalid: excessive decimals
+validate_price_response(1_000_000, 31)?;
+```
+
+## Safety Guarantees
+
+1. **No Overflow**: All validations prevent i128 overflow
+2. **No Negative Balances**: Strategy cannot report negative totals
+3. **Atomicity**: Deposit/withdraw or fail, no partial states
+4. **Determinism**: Same inputs always produce same validation result
+5. **Fail-Safe**: Contract reverts on validation failure (partial execution prevention)
+
+## Integration Pattern
+
+### Calling a Strategy
+
+```rust
+fn call_strategy_total_value(strategy: &Address) -> Result<i128, VaultError> {
+    let client = StrategyClient::new(&env, strategy);
+    
+    // Call strategy
+    let value = client.total_value();
+    
+    // Validate response before using
+    strategy_validation::StrategyValidator::validate_total_value(value)?;
+    
+    Ok(value)
+}
+
+fn deposit_to_strategy(
+    strategy: &Address,
+    amount: i128,
+) -> Result<(), VaultError> {
+    let client = StrategyClient::new(&env, strategy);
+    
+    // Get pre-state
+    let pre_total = client.total_value();
+    strategy_validation::StrategyValidator::validate_total_value(pre_total)?;
+    
+    // Execute deposit
+    client.deposit(amount);
+    
+    // Get post-state and validate
+    let post_total = client.total_value();
+    strategy_validation::StrategyValidator::validate_deposit_result(
+        amount,
+        pre_total,
+        post_total,
+    )?;
+    
+    Ok(())
+}
+```
+
+## Error Codes
+
+| Error | Cause | Recovery |
+|-------|-------|----------|
+| `InvalidStrategyResponse` | Response violates validation rules | Retry or pause vault |
+| `StrategyValueOverflow` | Value exceeds safe bounds | Manual intervention |
+| `DecimalConversionOverflow` | Precision conversion would overflow | Change decimal handling |
+
+## Testing Strategy
+
+### Unit Tests
+
+Test each validation rule independently:
+- Positive/zero/negative values
+- Boundary values (MAX_STRATEGY_VALUE)
+- Valid decimal ranges
+- Deposit/withdrawal consistency
+
+### Property-Based Tests
+
+Generate random inputs and verify:
+- No validation allows negative balances
+- No validation allows overflow
+- Deposit increases total (or fees decrease it)
+- Withdrawal decreases total
+
+### Integration Tests
+
+Test with actual strategy mock:
+- Deposit → validate → withdraw sequence
+- Multiple deposits in sequence
+- Strategy returning edge-case values
+
+See `tests/operational_safety_tests.rs` for comprehensive test suite.
+
+## Future Enhancements
+
+1. **Dynamic validation thresholds**: Adjust based on asset class
+2. **Strategy reputation scoring**: Track validation failure history
+3. **Degraded-mode operation**: Handle validation failures gracefully
+4. **Extended metrics**: Collect and alert on pattern violations

+//! Utilization-based dynamic protocol fee curve.
+//!
+//! The static protocol fee (`DataKey::FeeBps`) charges the same rate no matter
+//! how much of the vault's capital is actually deployed. That leaves the vault
+//! with no lever to balance supply and demand: when almost everything is
+//! working inside the strategy, idle liquidity is scarce and withdrawals get
+//! queued, yet depositing stays exactly as cheap as it was at 10% utilization.
+//!
+//! This module supplies the missing lever — a **kinked linear fee curve** over
+//! the vault's utilization ratio:
+//!
+//! ```text
+//!   fee_bps
+//!      ▲
+//!  max ┤                                        ╱

+//!      0          kink              10_000
+//! ```
+//!
+//! Below the kink (`optimal_utilization_bps`) the fee climbs gently from
+//! `base_fee_bps` to `optimal_fee_bps`. Above it the curve steepens toward
+//! `max_fee_bps`, so the scarcer idle liquidity becomes, the more the protocol
+//! charges on incoming yield.
+//!
+//! ## Rounding
+//!
+//! Every interpolation uses **floor division**, matching the policy in
+//! [`crate::fee_math`]: the vault never rounds a fee up, so a sub-basis-point
+//! remainder always stays with depositors.
+//!
+//! ## Safety properties enforced here
+//!
+//! * [`validate`] rejects any curve that is not monotonically non-decreasing
+//!   (`base <= optimal <= max`), so a "dynamic" curve can never be shaped to
+//!   charge *less* at high utilization than at low.
+//! * Every leg is bounded by `max_fee_bps <= 10_000`, so
+//!   [`fee_bps_at`] always returns a value [`crate::fee_math`] accepts.
+//! * The curve is **disabled by default**. Until governance explicitly enables
+//!   one, the vault keeps charging the static `fee_bps` exactly as before.

 /// Client for reading price data from the configured oracle.
+///
+/// ## Vault dependency on this interface
+///
+/// The vault only calls `get_price` from [`YieldVault::total_assets`] (and,
+/// transitively, [`YieldVault::invest`]), and only when both
+/// [`YieldVault::is_oracle_enabled`] is `true` and
+/// [`YieldVault::price_oracle`] is configured. Every response is passed
+/// through [`oracle::OracleValidator::validate_price_data`] before it is
+/// trusted; see the [`oracle`] module docs for the full stale-data policy
+/// (heartbeat freshness capped by `set_oracle_heartbeat`, non-future
+/// timestamps, sane price/decimals bounds, and the deviation circuit
+/// breaker versus the last validated price). Any validation failure reverts
+/// the call with `VaultError::OracleValidationFailed` — the vault never
+/// falls back to a cached, default, or otherwise synthesized price.
+///
+/// ## Responsibilities of an implementation
+///
+/// - `get_price` must return the best data currently available and must
+///   NOT itself substitute a stale, cached, or placeholder price when the
+///   real feed is unavailable — silently returning fallback data here
+///   would defeat the vault's staleness checks, since the vault has no way
+///   to distinguish a genuine fresh read from a fabricated one.
+/// - The returned timestamp must reflect when the underlying price was
+///   actually observed, not the time of the call, so the vault's heartbeat
+///   check reflects true data age.
+/// - If no reliable price can be produced, the implementation should panic
+///   (reverting the call) rather than return degraded data; the vault
+///   treats a reverted oracle call the same as a failed validation.

+//! Liquidation and recovery safeguards for strategy shortfalls (Issue #1165).
+//!
+//! A strategy can report back less value than the vault deployed into it —
+//! through a defaulted RWA tranche, an oracle-reported markdown, or a bug in the
+//! strategy adapter. Left unhandled, the vault keeps quoting a share price that
+//! its assets no longer back, and the first movers redeem at par while the last
+//! movers absorb the entire loss.
+//!
+//! This module is a *pure* decision layer evaluated **before** any state is
+//! mutated, mirroring [`crate::withdrawal_queue_safety`]: it classifies the
+//! shortfall, gates recovery execution behind explicit preconditions, and
+//! computes the loss socialisation that keeps the share price honest.
+//!
+//! ## Responsibilities
+//!
+//! - [`assess_shortfall`] — classify a strategy position as healthy, degraded,
+//!   or impaired against an operator-configured tolerance.
+//! - [`check_recovery_preconditions`] — reject recovery attempts made under
+//!   invalid conditions (live vault, missing governance approvals, no measured
+//!   shortfall, over-sized recovery amount).
+//! - [`socialize_loss`] — apply an impairment to the vault's asset base with
+//!   saturating, non-negative arithmetic.
+//!
+//! Operator and governance responsibilities are documented in
+//! `docs/runbooks/VAULT_LIQUIDATION_RECOVERY.md`.
+//!
+//! ## Error-code reuse
+//!
+//! The Soroban error enum is capped at 50 cases (see [`crate::errors`]), so this
+//! module deliberately reuses existing codes rather than defining new ones:
+//!
+//! | Condition | Code |
+//! |---|---|
+//! | No strategy configured | [`VaultError::StrategyNotConfigured`] |
+//! | Non-positive / corrupt amounts | [`VaultError::InvalidAmount`] |
+//! | `tolerance_bps` outside `0..=10_000` | [`VaultError::InvalidRiskThreshold`] |
+//! | Fewer approvals than required | [`VaultError::GovernanceThresholdNotMet`] |
+//! | Vault still live (not paused) | [`VaultError::RescueUnauthorized`] |
+//! | Recovery amount exceeds the measured shortfall | [`VaultError::ExceedsRiskThreshold`] |
+//! | Arithmetic overflow | [`VaultError::MathOverflow`] |

+//! Transactional accounting model and recovery regression tests (Issue #1172).
+//!
+//! Complex operator sequences — a deposit, then a withdrawal, then a fee change,
+//! then a retry of the step that failed — are exactly where a vault ends up in an
+//! inconsistent state. A Soroban transaction rolls back on panic, but a call that
+//! returns `Err` after *partially* mutating storage does not: the vault keeps the
+//! half-applied write.
+//!
+//! This module encodes the vault's accounting as an explicit state machine where
+//! [`apply`] is **transactional by construction**: it validates every
+//! precondition, computes the whole next state, and only then returns it. A
+//! failing step returns `Err` and hands back nothing, so the caller's state is
+//! provably untouched. [`apply_sequence`] runs a list of steps under that rule
+//! and reports where the sequence stopped.
+//!
+//! The tests below are the regression suite the issue asks for: they interleave
+//! deposits, withdrawals, yield accrual, and fee changes with injected failures,
+//! then assert that
+//!
+//! 1. the state after an interrupted step is byte-identical to the state before,
+//! 2. [`check_invariants`] still holds at every point in the sequence, and
+//! 3. re-running the failed step after the operator fixes the input succeeds and
+//!    lands on the same state as if the failure had never happened.
+//!
+//! The developer-facing recovery procedure is documented in
+//! `docs/runbooks/VAULT_LIQUIDATION_RECOVERY.md`.

+//! Protocol-level risk limits for vault exposure (Issue #1173).
+//!
+//! Hard caps that apply on top of per-strategy `StrategyCap` /
+//! `StrategyRiskThreshold`. They reduce how much the vault can take on
+//! under volatility or strategy stress.
+//!
+//! Default configuration is **unlimited** so existing deployments and
+//! tests keep their current behaviour. Operators opt in by setting
+//! non-default caps.
+//!
+//! Error-code reuse (Soroban enum cap of 50 cases):
+//!
+//! | Condition | Code |
+//! |---|---|
+//! | Negative TVL / amount | [`VaultError::InvalidAmount`] |
+//! | BPS outside `0..=10_000` | [`VaultError::InvalidRiskThreshold`] |
+//! | Deposit would exceed max TVL | [`VaultError::ExceedsRiskThreshold`] |
+//! | Invest would exceed concentration or deployed BPS | [`VaultError::ExceedsRiskThreshold`] |
+//!
+//! See `docs/PROTOCOL_RISK_LIMITS.md` for thresholds and override conditions.

+//! Gated contract telemetry and debugging hooks (Issue #1174).
+//!
+//! Diagnosing a vault incident from the outside means reconstructing state from
+//! a dozen separate getter calls, each a round trip, none of them consistent
+//! with one another. This module exposes a single consistent snapshot of the
+//! vault's high-value accounting plus a derived health classification, so an
+//! operator can answer "what is the vault doing right now" in one call.
+//!
+//! ## Gating
+//!
+//! Diagnostics are **off by default** and are turned on by the admin via
+//! `set_diagnostics_enabled`. When disabled, [`require_enabled`] rejects the
+//! read. This keeps the hook out of the default attack surface and makes
+//! enabling it an auditable, admin-authorised action.
+//!
+//! ## What is deliberately *not* exposed
+//!
+//! The snapshot carries **aggregates only**. It contains no addresses, no
+//! per-user balances, no pending-proposal contents, and no oracle credentials —
+//! nothing that is not already derivable from the vault's public getters. See
+//! [`DIAGNOSTIC_FIELD_POLICY`] and the `redacts_*` tests below, which exist to
+//! fail loudly if a future field breaks that rule.
+//!
+//! Operator usage is documented in `docs/runbooks/VAULT_DIAGNOSTICS.md`.

+## Overview
+
+The bridge compatibility layer provides a generic interface for cross-chain USDC transfers via bridge providers (Wormhole, LayerZero, etc.) on Stellar/Soroban.
+
+## Architecture
+
+```
+User -> BridgeCompat Contract -> Bridge Provider -> Destination Chain
+              \-> Fallback Provider (on primary failure)
+```
+
+### Contract: `bridge-compat`
+
+Located at `contracts/bridge-compat/`.
+
+## Adding a New Bridge Provider
+
+### Step 1: Implement the Provider Endpoint
+
+Create a Soroban contract that implements the bridge interaction logic:
+
+```rust
+// Example: contracts/my-bridge-endpoint/src/lib.rs
+#[contract]
+pub struct MyBridgeEndpoint;
+
+#[contractimpl]
+impl MyBridgeEndpoint {
+    pub fn send(env: Env, token: Address, amount: i128, recipient: Bytes, dest_chain: u32) {
+        // Bridge-specific logic here
+    }
+
+    pub fn estimate_fee(env: Env, amount: i128, dest_chain: u32) -> i128 {
+        // Return estimated fee in token units
+    }
+
+    pub fn supported_chains(env: Env) -> Vec<u32> {
+        // Return list of supported destination chain IDs
+    }
+}
+```
+
+### Step 2: Register the Provider
+
+```rust
+// Via BridgeCompat contract
+bridge_compat.register_provider(
+    env,
+    String::from_str(&env, "MyBridge"),          // name
+    BridgeProviderKind::Custom,                    // kind
+    my_bridge_endpoint_address,                    // endpoint contract
+    100,                                           // fee_bps (1%)
+    500_000_000_000,                               // max_transfer (500K USDC)
+    Vec::from_array(&env, &[1, 2, 3]),            // supported chain IDs
+);
+```
+
+### Step 3: Configure as Default (Optional)
+
+```rust
+bridge_compat.set_default_provider(env, provider_id);
+```
+
+## Supported Bridge Providers
+
+| Provider | Kind | Stellar Support | Status |
+|----------|------|-----------------|--------|
+| Wormhole | BridgeProviderKind::Wormhole | Experimental | Ready for testnet |
+| LayerZero | BridgeProviderKind::LayerZero | Experimental | Ready for testnet |
+| Custom | BridgeProviderKind::Custom | Via adapter | Flexible |
+
+## Chain IDs
+
+Chain identifiers follow the Wormhole convention:
+
+| Chain | ID |
+|-------|----|
+| Stellar | 0 |
+| Ethereum | 2 |
+| Solana | 1 |
+| Polygon | 5 |
+| BSC | 4 |
+| Avalanche | 6 |
+| Arbitrum | 23 |
+
+## Transfer Flow
+
+1. **Estimate**: Call `estimate_transfer()` to get fee and receive amount
+2. **Initiate**: Call `transfer_out()` with sender auth
+3. **Bridge**: The bridge endpoint processes the cross-chain transfer
+4. **Confirm**: Admin or relayer calls `confirm_transfer()` on completion
+5. **Refund**: If bridge fails, admin calls `fail_transfer()` to refund
+
+## Fallback Handling
+
+When the primary bridge provider fails:
+
+1. The transfer status is set to `Failed`
+2. Admin initiates refund via `fail_transfer()`
+3. Tokens are returned to the sender
+4. Optionally, retry with a different provider
+
+## Transfer Limits
+
+Configurable per bridge instance:
+
+- **Per-transfer limit**: Maximum amount per single transfer
+- **Epoch volume limit**: Maximum total volume within a time window
+- **Epoch duration**: Time window for volume tracking (default 24h)
+
+## Testnet Deployment
+
+```bash
+# Deploy bridge-compat contract
+soroban contract deploy \
+  --wasm contracts/bridge-compat/target/wasm32-unknown-unknown/release/bridge_compat.wasm \
+  --network testnet
+
+# Initialize
+soroban contract invoke \
+  --id <CONTRACT_ID> \
+  --fn initialize \
+  --arg <ADMIN_ADDRESS> \
+  --arg <USDC_TOKEN_ADDRESS> \
+  --network testnet
+
+# Register a provider
+soroban contract invoke \
+  --id <CONTRACT_ID> \
+  --fn register_provider \
+  --arg "Wormhole" \
+  --arg 0 \
+  --arg <ENDPOINT_ADDRESS> \
+  --arg 50 \
+  --arg 1000000000000 \
+  --arg '[1,2,3]' \
+  --network testnet
+```
+
+## Security Considerations
+
+- Admin-only provider registration and configuration
+- Transfer limits prevent excessive capital movement
+- Nonce-based replay protection
+- Token balance checks before transfer
+- Epoch-based volume tracking prevents flash-loan attacks
+
+## Future Enhancements
+
+1. **Relayer network**: Decentralized relayers for automatic confirmation
+2. **Oracle integration**: Price feeds for cross-chain value parity
+3. **Multi-hop routing**: Route through intermediate chains for better rates
+4. **Batch transfers**: Aggregate multiple small transfers
+5. **Automatic failover**: Switch providers without admin intervention

+# Dependency Update Policy
+
+> **Related docs:**
+> - [Dependency Review Process](./DEPENDENCY_REVIEW_PROCESS.md) — recurring review cadence, ownership, and outcome documentation
+> - [Security Scanning Guide](./SECURITY_SCANNING_GUIDE.md) — CVE tooling and scanner configuration
+> - [Code Review Standards](./CODE_REVIEW_STANDARDS.md) — general PR review expectations
+> - [CODEOWNERS](../.github/CODEOWNERS) — authoritative owner list per surface
+
+This document defines **policy** — the rules governing how dependencies are upgraded across the YieldVault-RWA monorepo. It applies to all three layers: Soroban smart contracts (Rust/Cargo), backend (Node.js/npm), and frontend (Node.js/npm). The companion [Dependency Review Process](./DEPENDENCY_REVIEW_PROCESS.md) covers the recurring review workflow and outcome documentation requirements.
+
+---
+
+## 1. Scope
+
+| Layer | Manifest | Package manager |
+|-------|----------|-----------------|
+| Contracts | `/Cargo.toml`, `*/Cargo.toml` | Cargo |
+| Backend | `backend/package.json` | npm |
+| Frontend | `frontend/package.json` | npm |
+| Root tooling | `/package.json` | npm |
+
+All four surfaces are in scope. Transitive (indirect) dependencies surfaced by Dependabot alerts or audit tools are subject to the same rules as direct dependencies.
+
+---
+
+## 2. Upgrade Cadence
+
+### 2.1 Automated Dependabot updates
+
+Dependabot is configured for daily runs on all three surfaces. PRs raised automatically by Dependabot follow this merge policy:
+
+| Update type | Target SLA | Who may merge |
+|-------------|-----------|---------------|
+| **Security patch** (any severity) | ≤ 48 hours | Surface owner (after CI green) |
+| **Patch** (non-security) | ≤ 2 weeks | Surface owner (after CI green) |
+| **Minor** | Next scheduled sprint | Surface owner with one peer review |
+| **Major** | Requires owner sign-off (see §4) | Surface owner + one additional maintainer |
+
+### 2.2 Manual / planned upgrades
+
+Outside Dependabot, dependency upgrades are permitted only via a `chore/*` branch (see [CONTRIBUTING.md](../CONTRIBUTING.md#branching-strategy)). Examples:
+
+```
+chore/upgrade-prisma-6
+chore/bump-stellar-sdk-minor
+chore/rust-soroban-sdk-2
+```
+
+Manual upgrades follow the same review criteria as automated ones but require the author to explicitly document the reason in the PR description.
+
+### 2.3 Layer-specific cadence
+
+| Layer | Patch | Minor | Major |
+|-------|-------|-------|-------|
+| **Frontend** (user-facing) | As PRs arrive (≤ 2 weeks) | Sprint boundary | Planned release only |
+| **Backend** (API/services) | As PRs arrive (≤ 2 weeks) | Sprint boundary | Planned release only |
+| **Contracts** (on-chain Rust) | As PRs arrive (≤ 2 weeks) | Sprint boundary | Security audit gate required |
+| **Root tooling** | As PRs arrive (≤ 1 month) | Quarterly | Quarterly |
+
+Contract-layer major upgrades require a security audit checkpoint before merging. See §4.
+
+---
+
+## 3. Testing Gates
+
+All dependency update PRs must pass the following CI gates before merge. A PR with failing gates **must not** be merged, even for security patches — fix the breakage first.
+
+### 3.1 Minimum gates (all layers)
+
+- [ ] Linting passes (`npm run lint` / `cargo fmt --check`)
+- [ ] Unit tests pass (`npm test` / `cargo test`)
+- [ ] Build succeeds (`npm run build` / `cargo build --release`)
+
+### 3.2 Extended gates (required for minor and major updates)
+
+| Layer | Additional gate |
+|-------|----------------|
+| **Frontend** | Vitest unit suite + Cypress E2E smoke (`npm run test:e2e`) |
+| **Backend** | Jest integration tests (`npm run test:integration`) |
+| **Contracts** | Full `cargo test` including mock-strategy and oracle crates |
+
+### 3.3 Gate bypass
+
+No bypass is permitted for security patches unless:
+1. The breakage is isolated to a test fixture unrelated to the vulnerability fix, **and**
+2. A follow-up issue is filed within 24 hours to restore the test.
+
+Bypasses require explicit written approval from the relevant surface owner and must be documented in the PR.
+
+---
+
+## 4. Major Update Owner Requirements
+
+A major version bump (semver `X.0.0` where `X` increases) triggers the following additional requirements:
+
+1. **Designated owner.** The owner defined in [CODEOWNERS](../.github/CODEOWNERS) for that surface must approve the PR. Approval from a different team member is insufficient.
+
+2. **Changelog review.** The PR description must include a summary of breaking changes extracted from the upstream changelog or migration guide, with explicit notes on how each breaking change is handled.
+
+3. **Migration plan.** If the upgrade requires code changes (API renames, removed exports, config changes), those changes must be included in the same PR or a linked PR that merges simultaneously.
+
+4. **Staging validation.** Major updates to backend or frontend must be validated in the staging environment before merge to `main`. Contract major upgrades require testnet deployment validation.
+
+5. **Contract layer additional gate.** Major Rust/Soroban SDK upgrades require:
+   - Sign-off from `@YieldVault-RWA/contracts-maintainers` **and** `@YieldVault-RWA/security-team`
+   - A security audit checkpoint or a scoped internal audit of changed surfaces
+   - Testnet deployment and smoke test prior to merge
+
+6. **Announcement.** Post a summary in the team's governance/update channel at least 24 hours before merging a major update, to allow any last-minute objections.
+
+---
+
+## 5. High-Risk Library List
+
+The following libraries have elevated risk due to their role in security, cryptography, or protocol correctness. Updates to these packages require explicit review by the security team (`@YieldVault-RWA/security-team`) regardless of whether the update is patch, minor, or major.
+
+### 5.1 Contracts (Rust/Cargo)
+
+| Crate | Risk reason |
+|-------|-------------|
+| `soroban-sdk` | Core on-chain execution environment |
+| `soroban-auth` | Authentication primitives |
+| `stellar-xdr` | Ledger XDR encoding — any change can affect fund transfers |
+| Any crate touching `i128` fixed-point arithmetic | Yield and share calculation correctness |
+
+### 5.2 Backend (npm)
+
+| Package | Risk reason |
+|---------|-------------|
+| `@stellar/stellar-sdk` | Signs and submits on-chain transactions |
+| `@prisma/client` / `prisma` | Database ORM; schema migration risk |
+| `jsonwebtoken` / `jose` | Auth token signing and verification |
+| `express` / `fastify` | Core HTTP server; security surface |
+| `helmet` | Security headers |
+| `bcrypt` / `argon2` | Password hashing |
+| Any HMAC/webhook-signing library | Webhook signature integrity |
+
+### 5.3 Frontend (npm)
+
+| Package | Risk reason |
+|---------|-------------|
+| `@stellar/freighter-api` | Wallet connection and transaction signing |
+| `@stellar/stellar-sdk` | On-chain data parsing and XDR handling |
+| Any content-security-policy or sanitization library | XSS risk |
+
+### 5.4 Review requirements for high-risk libraries
+
+- One additional approver from `@YieldVault-RWA/security-team` required (all update types).
+- PR description must explicitly state: "High-risk library update — security review required."
+- If the update is patch-only and purely a CVE fix with no API changes, the security team approver may fast-track within 24 hours.
+
+---
+
+## 6. CVE and Security Advisory Review Criteria
+
+When a CVE or GitHub Security Advisory (GHSA) is raised against a dependency, use the following criteria to determine required action.
+
+### 6.1 Severity tiers
+
+| CVSS Score | Severity | Required action | SLA |
+|------------|----------|----------------|-----|
+| 9.0–10.0 | Critical | Upgrade or mitigate immediately; block release if unresolved | 24 hours |
+| 7.0–8.9 | High | Upgrade in current sprint; must be resolved before next release | 72 hours |
+| 4.0–6.9 | Medium | Upgrade in next sprint unless mitigation is in place | 2 weeks |
+| 0.1–3.9 | Low | Upgrade at next scheduled review | Next review cycle |
+
+### 6.2 Exploitability assessment
+
+Before escalating a CVE, assess:
+
+1. **Is the vulnerable code path reachable?** (e.g., a server-side vulnerability in a browser-only package is irrelevant)
+2. **Is the affected feature used by YieldVault?** Check the relevant surface's imports.
+3. **Does a patched version exist?** If not, document a mitigation plan (e.g., WAF rule, feature flag, code-level guard).
+4. **Is this a false positive?** Consult [False Positive Handling](./FALSE_POSITIVE_HANDLING.md) before dismissing.
+
+### 6.3 Breaking changes in security fixes
+
+If a security patch introduces a breaking API change (uncommon but possible), the update is treated as a **major update** (see §4) with a fast-track SLA applied based on severity.
+
+### 6.4 No-fix advisories
+
+If no upstream fix exists within the SLA window:
+- Document the CVE and mitigation in the tracking issue.
+- Evaluate replacing the dependency with an alternative.
+- Escalate to `@YieldVault-RWA/security-team` for risk acceptance sign-off.
+- Record the risk-acceptance decision in the relevant PR or tracking issue.
+
+---
+
+## 7. Dependency Freeze During Release Windows
+
+During release freezes (see [Release Train Cadence](./RELEASE_TRAIN_CADENCE_AND_FREEZE_POLICY.md)):
+
+- Non-security dependency updates are **deferred** until the freeze lifts.
+- Security patches classified High or Critical **may** be merged during a freeze with explicit approval from the release engineer.
+- Any merge during a freeze requires a fast-follow patch release plan if it introduces unexpected breakage.
+
+---
+
+## 8. Dependency Addition Policy
+
+Adding a **new** dependency (not an upgrade) follows stricter rules than updating an existing one:
+
+1. **Necessity check.** Can the need be met with an existing dependency or standard library? If yes, prefer that.
+2. **Maintenance health.** Check:
+   - Last release date (reject if >18 months with no activity, unless intentionally stable)
+   - Number of maintainers (flag if single-maintainer)
+   - Open critical CVEs
+3. **Pinned version.** New dependencies must use an exact version in the manifest (no `^` or `~` ranges for production deps in contracts and backend). Frontend may use `^` for minor ranges on non-security-sensitive packages.
+4. **License compatibility.** Confirm the license is compatible with YieldVault's distribution terms. Flag any GPL/AGPL-licensed package for legal review before adding.
+5. **Tree-shaking and bundle size.** For frontend additions, check the bundle size impact. Packages adding >20 KB gzipped to the main bundle require explicit justification.
+6. **Review requirement.** New dependency additions require one additional reviewer beyond the standard code owner, regardless of surface.
+
+---
+
+## 9. Exceptions and Waivers
+
+Any deviation from this policy requires:
+
+1. A written rationale in the PR description or a linked issue.
+2. Explicit approval from the relevant surface owner and one core maintainer.
+3. A follow-up issue filed to resolve the exception (with a due date).
+
+Repeated exceptions for the same dependency or surface should trigger a policy review.
+
+---
+
+## 10. Policy Ownership and Review
+
+| Role | Responsibility |
+|------|---------------|
+| `@YieldVault-RWA/core-maintainers` | Policy owner; approve material changes to this document |
+| `@YieldVault-RWA/security-team` | CVE criteria and high-risk library list |
+| `@YieldVault-RWA/contracts-maintainers` | Cargo/Soroban-specific rules |
+| `@YieldVault-RWA/devops-maintainers` | Dependabot config and CI gate enforcement |
+
+This policy is reviewed **quarterly** alongside the dependency review metrics (see §8 of [Dependency Review Process](./DEPENDENCY_REVIEW_PROCESS.md)).

+# Feasibility Study: ERC-404 Token Support
+
+**Issue:** #1225  
+**Status:** Research Complete  
+**Date:** 2026-08-26  
+
+## Executive Summary
+
+ERC-404 is a hybrid token standard on EVM chains that combines ERC-20 fungibility with ERC-721 NFT characteristics. This study evaluates whether YieldVault-RWA should support ERC-404-style tokens on Stellar/Soroban.
+
+**Recommendation:** Implement a Soroban-native semi-fungible token (SFT) adapter rather than direct ERC-404 port, as ERC-404 is EVM-specific and Stellar has its own token primitives.
+
+## Background
+
+### What is ERC-404?
+
+ERC-404 is an EVM token standard that creates a 1:1 binding between fungible tokens (ERC-20) and non-fungible tokens (ERC-721):
+
+- Holding whole tokens = holding the associated NFT
+- Transferring fractional amounts = burning/minting NFTs dynamically
+- No separate "claim" step — NFT ownership automatically tracks token balance
+- Enables fractional NFT trading with ERC-20 liquidity
+
+### Key Properties
+
+| Property | ERC-404 (EVM) | Soroban Equivalent |
+|----------|---------------|-------------------|
+| Fungible base | ERC-20 | Stellar Asset Contract (SAC) |
+| Non-fungible component | ERC-721 | Custom NFT contract |
+| Binding mechanism | Contract-level | Custom adapter contract |
+| Fractional ownership | Native | Requires accounting layer |
+| Transfer hooks | `transfer()` override | Soroban `transfer()` + custom logic |
+
+## Analysis: Stellar/Soroban Compatibility
+
+### Current Vault Architecture
+
+YieldVault-RWA uses:
+- **Underlying asset:** USDC (Stellar Asset Contract / SAC)
+- **Vault shares:** Internal accounting via `ShareBalance` storage keys (not a minted token)
+- **Token interaction:** `soroban_sdk::token::Client` for SAC transfers
+
+The vault currently supports:
+- ERC-4626-style deposits (deposit USDC, get internal shares)
+- Strategy allocation (invest USDC in yield strategies)
+- No external token contract for vault shares
+
+### ERC-404 on Stellar: Challenges
+
+#### 1. No Native ERC-404 Equivalent
+Stellar does not have a built-in semi-fungible token standard. The closest equivalents are:
+- **Stellar Asset Contracts (SAC):** Fungible only (like ERC-20)
+- **Custom Soroban NFT contracts:** Non-fungible only (like ERC-721)
+- **Separate accounting:** Track fungible + non-fungible separately
+
+#### 2. Token Transfer Hooks
+ERC-404 overrides `transfer()` to automatically burn/mint NFTs. On Soroban:
+- SAC `transfer()` cannot be overridden (it's a protocol-level contract)
+- Custom token contracts can implement hooks, but are not SAC-compatible
+- Would require a wrapper contract around the base asset
+
+#### 3. Fractional Share Implications
+If vault shares were ERC-404-style:
+- Users holding fractional shares (e.g., 1.5 yvUSDC) would NOT get the associated NFT
+- Only whole-number holders get the NFT component
+- This creates a "dead zone" for fractional holders
+- Incompatible with the vault's current fractional share model (shares are always fractional)
+
+#### 4. Gas/Compute Costs
+ERC-404's automatic NFT minting on every whole-number boundary crossing:
+- Doubles compute cost per transfer (SAC transfer + NFT mint/burn)
+- Increases storage costs (NFT metadata storage)
+- Soroban's compute budget may make this expensive
+
+### Potential Implementation Path
+
+If ERC-404 support is desired, the recommended approach is a **Soroban SFT Adapter**:
+
+```
+┌─────────────────────────────────────────┐
+│           SFT Adapter Contract          │
+│  ┌──────────┐    ┌──────────────────┐  │
+│  │  SAC      │    │  NFT Contract    │  │
+│  │ (USDC)   │    │  (Fractional     │  │
+│  │          │    │   ownership)     │  │
+│  └──────────┘    └──────────────────┘  │
+└─────────────────────────────────────────┘
+```
+
+The adapter would:
+1. Accept deposits of the base token (USDC)
+2. Track fractional ownership internally
+3. Mint NFTs when users reach whole-number thresholds
+4. Burn NFTs when users transfer below thresholds
+5. Maintain a claim/redeem mechanism for NFT ↔ token conversion
+
+### Migration Path
+
+For YieldVault-RWA specifically:
+
+1. **Phase 1 (Current):** Internal share accounting (no external token)
+2. **Phase 2 (Optional):** Wrapped vault share token (yvUSDC as a real Soroban token)
+3. **Phase 3 (Optional):** SFT adapter for yvUSDC with NFT components
+4. **Phase 4 (Future):** Cross-chain ERC-404 via bridge compatibility layer
+
+## Risks and Benefits
+
+### Benefits
+- **Enhanced UX:** Users could hold vault positions as tradeable NFTs
+- **Composability:** NFT-based vault shares could integrate with Soroban NFT marketplaces
+- **New use cases:** Collateralized vault positions, fractional position trading
+- **Marketing:** ERC-404 compatibility signals innovation to the community
+
+### Risks
+- **Complexity:** Adds a significant new contract and storage model
+- **Security surface:** NFT minting/burning logic creates new attack vectors
+- **Gas costs:** Double compute for every transfer operation
+- **Incompatibility:** Current fractional share model directly conflicts with ERC-404 whole-number binding
+- **Maintenance burden:** Two token models to maintain (internal + SFT)
+
+## Recommendation
+
+### Do NOT implement ERC-404 directly
+- ERC-404 is an EVM standard; Stellar has different primitives
+- The fractional share model is incompatible with whole-number NFT binding
+- The complexity outweighs the benefits for an RWA vault
+
+### DO consider a wrapped vault token
+If enhanced composability is desired:
+1. Create a `yvUSDC` Soroban token contract (standard SAC)
+2. Users wrap their internal shares into the tradeable token
+3. This is simpler than ERC-404 and compatible with Stellar ecosystem
+
+### DO track ERC-404 ecosystem evolution
+- Monitor Stellar Improvement Proposals (SEPs) for SFT standards
+- Watch for Soroban token extensions that could enable SFT patterns
+- Re-evaluate if a Soroban-native SFT standard emerges
+
+## Appendix: ERC-404 Reference
+
+### ERC-404 Specification (EVM)
+- Token balance tracks both fungible and non-fungible components
+- `transfer()` automatically burns/mints NFTs at whole-number boundaries
+- `totalSupply()` returns fungible token supply
+- NFT ownership is a derivative of token balance, not independent
+
+### Soroban Token Standards
+- **SAC (Stellar Asset Contract):** Native asset wrapping, fungible only
+- **SEP-41:** Token interface (similar to ERC-20)
+- **Custom NFT contracts:** No standard yet; typically use metadata + ownership tracking
+
+### Related Work
+- **Fractional.art (EVM):** ERC-20 backed by locked NFTs (inverse of ERC-404)
+- **Charged Particles (EVM):** Multi-token NFTs with yield
+- **Soroban NFTs:** Community-driven, no official standard yet

+# Oracle Failure Handling (Issue #1231)
+
+Procedures for heartbeat failures, deviation spikes, network partitions, and
+timeouts. Implementation lives in:
+
+- Validator: `contracts/vault/src/oracle.rs`
+- Mock feed: `contracts/mock-strategy/src/mock_oracle.rs`
+- Tests: `contracts/vault/src/oracle_failure_tests.rs`
+
+The vault is **fail-closed**. Invalid oracle data never falls back to a cached
+or stale price. `total_assets()` (and anything that calls it, including
+`invest`) aborts.
+
+## Failure modes
+
+| Mode | Mock API | Validator error | Operator meaning |
+| --- | --- | --- | --- |
+| Heartbeat / stale | `StaleHeartbeat` or ledger time > heartbeat | `HeartbeatExceeded` | Feed stopped updating |
+| Deviation spike | `DeviationSpike` (3× last price) | `PriceDeviationExceeded` | Flash crash / manipulation |
+| Zero / negative | `ZeroPrice` / `NegativePrice` | `PriceZero` | Corrupt payload |
+| Bad decimals | `InvalidDecimals` | `InvalidDecimals` | Precision attack |
+| Future timestamp | `FutureTimestamp` | `TimestampInFuture` | Clock / injection |
+| Network partition | `NetworkPartition` | host panic `oracle network partition` | Oracle contract unreachable |
+| RPC / call timeout | `Timeout` | host panic `oracle timeout` | Call does not return |
+
+Heartbeat default is **3600s**. Deviation circuit breaker default is **5000 bps
+(50%)** vs the last *validated* price (`LastValidatedPrice`).
+
+## Handling procedure
+
+1. **Confirm** — `try_total_assets` / RPC error. Pause reason should be
+   `PauseReason::OracleFailure` if the vault is halted.
+2. **Halt price-sensitive flow** — do not invest, divest-for-rebalance, or
+   quote TVL from the failed feed. Deposits that do not consult the oracle
+   still mint against accounting state; prefer pausing if the feed is required
+   for user-facing NAV.
+3. **Classify**
+   - Heartbeat / timeout: wait for a fresh push, or rotate the oracle via the
+     timelocked `queue_price_oracle_change` → `execute_price_oracle_change`.
+   - Deviation spike: do **not** widen `MAX_PRICE_DEVIATION_BPS` in an
+     incident. Investigate the upstream feed; resume only after a new price
+     is within 50% of the last validated value or after a deliberate admin
+     oracle rotation (which clears the last-price cache on a new address
+     only after the next successful read).
+   - Partition: restore the RPC / contract; the mock `NetworkPartition` flag
+     is the test stand-in.
+4. **Resume** — `set_oracle_enabled(true)` only if it was turned off. Call
+   `total_assets` once in a dry-run / testnet check. Unpause if paused.
+5. **Disable (last resort)** — `set_oracle_enabled(false)` skips the feed.
+   Phase 1 defaults to disabled. Production should keep it enabled once the
+   feed is live.
+
+## Tests
+
+```bash
+cargo test -p vault oracle
+cargo test -p mock-strategy
+```
+
+Coverage target for oracle modules is **≥ 90%** of validator branches
+(heartbeat, deviation, bounds, slippage, conversion) plus every mock failure
+mode wired through the vault.

+# Contract Performance Regression Thresholds (Issue #1235)
+
+Nightly benchmarks measure Soroban **host** CPU instructions and memory bytes
+for core vault operations. This repo is Stellar/Soroban, so the equivalent of
+Foundry `forge test --gas-report` + Anvil is the Soroban test `Env` budget
+meter plus a scheduled GitHub Actions workflow.
+
+Numbers are **relative across commits**, not production WASM gas. Host metering
+underestimates VM instantiation.
+
+## Operations
+
+| Op | What is measured |
+| --- | --- |
+| `deposit` | Subsequent deposit (after a warm-up deposit) |
+| `withdraw` | Partial share redemption |
+| `invest` | Idle → strategy allocation |
+| `switch_strategy` | `set_strategy` between two Benji strategy instances (v1 ↔ v2) |
+
+Each op is reported once per strategy version so the nightly issue can compare
+implementations.
+
+## Thresholds
+
+Baseline: `contracts/vault/benches/baseline.json`
+
+| Field | Value |
+| --- | --- |
+| `regression_threshold_pct` | **15** |
+| Fail CI | any op's CPU or memory **> baseline × 1.15** |
+| Compare | max(v1, v2) for that op vs the baseline entry |
+
+If a real, accepted optimisation or feature increases cost, update the baseline
+in the same PR and explain why in the nightly issue / PR body.
+
+## How to run
+
+```bash
+bash contracts/vault/scripts/benchmark.sh
+```
+
+The script:
+
+1. Runs `cargo test -p vault --test benchmarks -- --nocapture`
+2. Parses `BENCH op=... cpu=... mem=...` lines
+3. Writes `benchmark-report.md` and `benchmark-results.json`
+4. Exits non-zero on a regression against `baseline.json`
+
+Nightly: `.github/workflows/nightly-benchmarks.yml` (02:00 UTC) posts the
+report to a GitHub Issue labeled `nightly-benchmark`.

+# Protocol Risk Limits (Issue #1173)
+
+Hard caps on vault exposure. They sit **on top of** per-strategy
+`set_strategy_cap` / `set_strategy_risk_threshold` and are defined in
+`contracts/vault/src/risk_limits.rs`.
+
+Defaults are unlimited so existing deployments keep working. Operators opt in
+by setting non-zero / sub-100% caps.
+
+## Thresholds
+
+| Limit | Storage | Default | Meaning |
+| --- | --- | --- | --- |
+| Max vault TVL | `Risk(MaxTvl)` | `0` (unlimited) | Hard cap on accounting `total_assets` for new deposits |
+| Max strategy concentration | `Risk(MaxConc)` | `10_000` (100%) | Max share of TVL in the strategy being invested into |
+| Max deployed capital | `Risk(MaxDep)` | `10_000` (100%) | Max share of TVL allocated out of idle |
+| Stress concentration | `Risk(StrConc)` | `5_000` (50%) | Used when stress mode is on |
+| Stress deployed | `Risk(StrDep)` | `7_000` (70%) | Used when stress mode is on |
+| Stress mode | `Risk(Stress)` | `false` | Selects the tighter of normal vs stress caps |
+
+Per-strategy caps still apply:
+
+- `StrategyCap(strategy)` — absolute token units
+- `StrategyRiskThreshold(strategy)` — bps of TVL, default 100%
+
+An invest must pass **both** the per-strategy checks and the protocol checks.
+
+## Enforcement
+
+| Action | Check | Error |
+| --- | --- | --- |
+| `deposit` / `gasless_deposit` / `batch_deposit` | `current_tvl + amount > max_vault_tvl` | `ExceedsRiskThreshold` |
+| `invest` | concentration or deployed BPS exceeded | `ExceedsRiskThreshold` |
+| `invest` | per-strategy absolute cap | `ExceedsStrategyCap` |
+| `invest` | per-strategy BPS threshold | `ExceedsRiskThreshold` |
+| `rebalance` into `to_strategy` | same protocol invest check | `ExceedsRiskThreshold` |
+| Setter BPS outside `0..=10000` | `validate_bps` | `InvalidRiskThreshold` |
+| Negative TVL | | `InvalidAmount` |
+
+Stress mode takes `min(normal_cap, stress_cap)` so it can only tighten limits.
+
+## Override conditions
+
+These are the only ways to raise or bypass a bound:
+
+1. **Admin raises the cap** — `set_max_vault_tvl`, `set_max_conc_bps`,
+   `set_max_deployed_bps`. Setting TVL back to `0` restores unlimited TVL.
+2. **Admin disables stress mode** — `set_stress_mode(false)` after volatility
+   subsides. This is the intended recovery path; it does not require a new cap
+   if the normal cap already allows the position.
+3. **Reduce exposure first** — `withdraw` (TVL) or `divest` (concentration).
+   Once the position is back under the cap, the same operation is allowed
+   again. There is no "force invest" flag.
+4. **Pause** — `pause(PauseReason::LiquidityCrisis | OracleFailure | …)` blocks
+   deposits and withdrawals entirely. Emergency approvers can pause independently
+   of admin. Pause is a halt, not a cap override.
+5. **Governance / admin strategy switch** — changing strategy does not raise
+   caps; `rebalance` still has to fit the destination strategy under the
+   protocol concentration cap.
+
+There is **no** runtime backdoor that lets an invest exceed a configured hard
+cap while the vault is live.
+
+## Recovery tests
+
+`contracts/vault/src/risk_limits_tests.rs` covers:
+
+- TVL overrun then withdraw then deposit
+- Strategy-cap overrun then divest then invest
+- Protocol concentration overrun then divest then invest
+- Stress mode tightening then `set_stress_mode(false)` override

+cargo test -p vault risk_limits

+1. **Change Window & Notice**: Announce scheduled release window in `#yieldvault-incidents` and status channels.
+2. **Database Backup**: Take a manual, verified snapshot of the production PostgreSQL database.
+3. **Contract Upgrade / Deployment**:
+   - **For Upgrades**: Follow `docs/runbooks/CONTRACT_UPGRADE_PLAYBOOK.md`:
+     1. Set pause: `soroban contract invoke --id <VAULT_ID> --source admin --network mainnet -- set_pause --paused true`.
+     2. Install new WASM: `soroban contract install --wasm <OPTIMIZED_WASM> --network mainnet`.
+     3. Execute upgrade via multisig: `soroban contract invoke --id <VAULT_ID> --source admin --network mainnet -- upgrade --new_wasm_hash <HASH>`.
+     4. Verify version & state: `soroban contract invoke --id <VAULT_ID> --network mainnet -- version`.
+     5. Unpause vault: `soroban contract invoke --id <VAULT_ID> --source admin --network mainnet -- set_pause --paused false`.
+   - **For Fresh Deployment**:
+     1. Deploy WASM: `soroban contract deploy --wasm <OPTIMIZED_WASM> --source deployer --network mainnet`.
+     2. Initialize vault parameters (Admin multisig, Treasury address, Fee BPS, Caps).
+     3. Record addresses in `deployments/contracts.mainnet.json`.
+4. **Backend Production Deployment**:
+   - Execute database migration: `npx prisma migrate deploy`.
+   - Deploy backend containers/instances with rolling update strategy (zero downtime).
+   - Confirm healthy readiness probe (`/ready`) across all backend instances.
+5. **Frontend Production Deployment**:
+   - Push release tag `v*.*.*` triggering `production-deploy.yml` (or trigger production Vercel deployment).
+   - Invalidate edge CDN cache if necessary.
+

+
+## 5. Post-Deployment Validation
+
+### 5.1 Immediate Checks (T+0 to T+10 min)
+- [ ] **Health & Readiness Endpoints**:
+  - `GET /health` returns HTTP 200 with status `"healthy"`.
+  - `GET /ready` returns HTTP 200 with status `{"ready": true}` and all subsystem probes green.
+- [ ] **Core API Responses**:
+  - `GET /api/v1/vault/summary` returns valid non-null numerical metrics.
+  - `GET /api/v1/transactions?limit=1` returns properly structured envelope.
+  - `GET /api/v1/vault/apy/history?days=7` responds within latency SLO.
+- [ ] **Frontend Verification**:
+  - App loads cleanly with no unhandled console errors or missing chunk errors.
+  - Connected wallet correctly identifies target network (no mismatch warning).
+  - Share price, APY, and Total Value Locked render accurately on the dashboard.
+- [ ] **Contract Smoke Invocations**:
+  - `total_assets()` matches expected on-chain accounting.
+  - `total_shares()` matches expected share issuance.
+  - `paused()` returns `false`.
+
+### 5.2 Extended Monitoring (T+10 to T+30 min)
+- [ ] **End-to-End User Journeys**:
+  - Perform test deposit transaction (or verify telemetry on live user deposits).
+  - Perform test withdrawal transaction.
+  - Confirm transactions appear in history index within 1 ledger close (~5 seconds).
+- [ ] **Telemetry & Error Budgets**:
+  - P95 latency on critical API endpoints remains under 200 ms.
+  - HTTP 5xx error rate remains < 0.1%.
+  - Zero unhandled exceptions in Sentry.
+  - Soroban RPC error rate < 1%.
+- [ ] **Background Workers**:
+  - APY snapshot background job running on schedule.
+  - Event indexing worker keeping pace with the Stellar ledger tip.
+

+
+## 6. Rollback Triggers & Procedures
+
+### 6.1 Rollback Activation Triggers
+Initiate immediate rollback if any of the following occur during the 30-minute validation window:
+- `/health` or `/ready` fails continuously for > 2 minutes.
+- HTTP 5xx error rate on critical write or read endpoints exceeds 5%.
+- Critical smart contract logic failure, accounting invariant violation, or unexpected revert on deposits/withdrawals.
+- Database data corruption or migration failure affecting core entities.
+- Active security vulnerability discovered or exploited.
+
+### 6.2 Rollback Actions by Layer
+- **Smart Contracts**:
+  1. Immediately pause vault: `soroban contract invoke --id <VAULT_ID> --source admin --network <network> -- set_pause --paused true`.
+  2. If upgrade corrupted logic: downgrade to previous known good WASM hash (`upgrade --new_wasm_hash <PREVIOUS_HASH>`).
+- **Backend Service**:
+  1. Roll back container image / deployment to previous git tag.
+  2. If migrations were executed, run designated down-migration: `psql -f backend/prisma/migrations/<version>/rollback.sql`.
+- **Frontend SPA**:
+  1. Trigger instant rollback in Vercel or point CDN traffic back to previous immutable build hash.
+- **Incident Escalation**:
+  1. Page Incident Commander and log event in `#yieldvault-incidents`.
+  2. Open postmortem tracking ticket.

+
+## 2. Ownership Boundaries
+
+### 2.1 Frontend
+
+**Owner:** `@YieldVault-RWA/frontend-maintainers`  
+**Source root:** `frontend/src/`  
+**Deployment:** Static SPA served at `http://localhost:5173` (dev) or CDN (prod)
+
+The frontend layer owns everything the user sees and initiates. It does not hold authoritative state — it is a consumer of backend REST responses and on-chain data. The frontend is responsible for:
+
+- Wallet connection and session management via Freighter (`WalletConnect.tsx`, `AuthContext.tsx`, `lib/walletSession.ts`)
+- Transaction building, simulation preview, and signing (`lib/vaultApi.ts`, `hooks/useVaultMutations.ts`)
+- Rendering vault state, APY charts, and transaction history (components in `components/`, pages in `pages/`)
+- Form validation and user-side input constraints (`forms/schemas/`, `forms/validate.ts`)
+- Reporting indexed transaction events back to the backend for off-chain record keeping (`lib/transactionApi.ts`)
+
+**What the frontend does NOT own:**
+- Authoritative vault share balances (owned by the contract's on-chain state)
+- Transaction history persistence (owned by the backend/database)
+- Webhook subscribers or event fan-out (owned by the backend)
+- Any admin or governance actions beyond initiating signed transactions
+
+### 2.2 Backend
+
+**Owner:** `@YieldVault-RWA/backend-maintainers`  
+**Source root:** `backend/src/`  
+**Port:** `3000`
+
+The backend layer owns all off-chain indexing, persistence, access control, and fan-out. It is the authoritative source for transaction history records, APY snapshots, webhook registrations, and rate-limiting state. It does not execute on-chain logic — it observes and indexes it. Key responsibilities:
+
+- Indexing on-chain events by polling Soroban RPC (`eventPollingService.ts`)
+- Persisting transactions, APY snapshots, and audit logs to PostgreSQL via Prisma
+- Enforcing access control (JWT auth, API keys, RBAC, wallet signature verification)
+- Orchestrating webhook delivery to subscribers with HMAC signing and retry (`webhookDelivery.ts`, `eventOutbox.ts`)
+- Providing a REST API for the frontend and external integrators
+- Rate limiting and idempotency enforcement
+
+**What the backend does NOT own:**
+- On-chain vault state (owned by the contract)
+- User wallet keys or signing (owned by the user's Freighter wallet)
+- Contract governance or upgrade decisions (owned by `@YieldVault-RWA/contracts-maintainers`)
+
+### 2.3 Contracts
+
+**Owner:** `@YieldVault-RWA/contracts-maintainers` (changes also require `@YieldVault-RWA/security-team`)  
+**Source root:** `contracts/`  
+**Language:** Rust → WebAssembly (Soroban)
+
+The contracts layer owns all authoritative on-chain state and invariants. Nothing the frontend or backend does can bypass the invariants enforced in contract code. Responsibilities:
+
+- Holding and accounting for deposited USDC, issued `yvUSDC` shares, and accrued yield
+- Enforcing deposit/withdrawal constraints (min deposit, per-user cap, large-withdrawal timelock)
+- Strategy management and DAO governance
+- Protocol fee accounting and timelocked admin parameter changes
+- RWA shipment provenance tracking
+- Emitting contract events (`deposit`, `pndwdraw`, `withdraw`, `feechg`, `mindepchg`)
+
+**What the contracts do NOT own:**
+- Off-chain records or analytics (owned by the backend)
+- Webhook delivery (owned by the backend)
+- UI presentation (owned by the frontend)
+
+---
+
+## 3. API Flow Maps
+
+### 3.1 Frontend → Backend REST API
+
+The frontend communicates with the backend via the HTTP REST API rooted at `VITE_API_BASE_URL` (default `http://localhost:3000`). The API client lives at `frontend/src/lib/api/client.ts`.
+
+| Frontend action | HTTP call | Backend handler |
+|-----------------|-----------|-----------------|
+| Index a deposit/withdrawal after on-chain confirmation | `POST /api/v1/vault/deposit` / `POST /api/v1/vault/withdraw` | `vaultEndpoints.ts` |
+| Fetch transaction history | `GET /api/v1/transactions?wallet=…` | `transactionEndpoints.ts` |
+| Fetch vault summary (APY, TVL, share price) | `GET /api/v1/vault/summary` | `vaultEndpoints.ts` |
+| Fetch portfolio / holdings | `GET /api/v1/portfolio/:wallet` | `listEndpoints.ts` |
+| Wallet login (nonce + sign) | `POST /api/v1/auth/nonce`, `POST /api/v1/auth/login` | `auth.ts` |
+| Refresh JWT | `POST /api/v1/auth/refresh` | `auth.ts` |
+| Check backend health | `GET /health` | `healthProbe.ts` |
+| Fetch APY history | `GET /api/v1/vault/apy-history` | `apySnapshot.ts` routes in `index.ts` |
+| Account statement export | `GET /api/v1/export/statement` | `exportJobs.ts` |
+| Referral info | `GET /api/v1/referral/:wallet` | `referralEndpoints.ts` |
+| Wallet alias | `GET/POST /api/v1/wallet/alias` | `walletAliasEndpoints.ts` |
+
+**Auth model:** The frontend authenticates using a two-step wallet-sign flow. It first requests a nonce from the backend, then signs it with Freighter, and exchanges the signature for a short-lived JWT. All subsequent API calls include the JWT in `Authorization: Bearer <token>`.
+
+### 3.2 Frontend → Soroban RPC (direct)
+
+Some frontend operations bypass the backend entirely and talk directly to the Stellar Soroban RPC node at `VITE_SOROBAN_RPC_URL`:
+
+| Frontend action | RPC call | Source |
+|-----------------|----------|--------|
+| Simulate deposit/withdrawal (fee/slippage preview) | `simulateTransaction` | `lib/vaultApi.ts` |
+| Submit signed deposit/withdrawal transaction | `sendTransaction` | `lib/vaultApi.ts` → `hooks/useVaultMutations.ts` |
+| Read share balance, share price, vault params | `invokeContractFunction` (view calls) | `lib/vaultApi.ts` |
+| Check USDC allowance | `invokeContractFunction` (SAC allowance) | `hooks/useTokenAllowance.ts` |
+
+These calls use `@stellar/stellar-sdk` and `@stellar/freighter-api`. The signed transaction XDR is constructed by the frontend, signed by Freighter, and submitted directly to the RPC node — the backend is not in the signing path.
+
+### 3.3 Backend → Soroban RPC (polling & read)
+
+The backend polls Soroban RPC independently to index on-chain events:
+
+| Backend action | RPC call | Source |
+|----------------|----------|--------|
+| Poll contract events | `getEvents(contractId, startLedger)` | `eventPollingService.ts` |
+| Read current vault state (reconciliation) | View invocations | `sorobanClient.ts` |
+| Batch-read multiple contract values | `sorobanBatchClient.ts` | `sorobanBatchClient.ts` |
+
+The backend does **not** submit on-chain transactions — it is a read-only observer of the chain. The circuit breaker (`circuitBreaker.ts`) protects the backend from cascading failures when the RPC node is degraded.
+
+---
+
+## 4. Event Flow Map
+
+Contract events emitted on-chain are the source of truth for all off-chain indexing and notifications. The flow from on-chain emission to subscriber webhook delivery is:

+```
+
+**Delivery guarantees:**
+- The outbox pattern (`eventOutbox.ts`) ensures an event is not lost between indexing and delivery, even if the delivery worker crashes.
+- `webhookDeduplication.ts` prevents duplicate deliveries on retry.
+- Failed deliveries are retried with exponential backoff; see [Webhook Integration Guide](./WEBHOOK_INTEGRATION.md) for retry limits and failure modes.
+
+**Frontend notification path (parallel):**
+After submitting a transaction, the frontend polls the backend's transaction endpoint (or uses the `usePolling` hook) rather than subscribing to webhooks directly. The frontend has no direct webhook consumer.
+
+---
+
+## 5. Cross-Layer Interface Assumptions
+
+These are the contracts between layers. A violation of any assumption on either side is an integration bug, not a product decision.
+
+### 5.1 Frontend → Backend assumptions
+
+| # | Assumption | Where enforced |
+|---|-----------|----------------|
+| F1 | Backend returns `application/json` for all REST endpoints. Non-2xx responses include an `error.code` and `error.message` field. | `lib/api/error.ts`, backend `middleware/apiError.ts` |
+| F2 | JWT tokens expire; the frontend must handle 401 responses by triggering refresh or re-login. | `lib/api/client.ts` (interceptor), `AuthContext.tsx` |
+| F3 | Pagination uses `page` / `pageSize` query params and returns a `data` array plus `pagination.total`. | `lib/transactionQuery.ts`, backend `pagination.ts` |
+| F4 | The backend `/health` endpoint returns within 2 seconds and reflects live DB and RPC connectivity. | `hooks/useHealthStatus.ts`, backend `healthProbe.ts` |
+| F5 | CORS allows the frontend origin (`VITE_API_BASE_URL` origin). The backend `cors.ts` middleware must include the deployed frontend origin. | `middleware/cors.ts` |
+| F6 | The correlation ID header (`X-Correlation-ID`) injected by the frontend is echoed back by the backend in responses and logs. | `components/CorrelationIdSync.tsx`, backend `middleware/correlationId.ts` |
+| F7 | Vault summary fields (`totalAssets`, `totalShares`, `sharePrice`, `apy`) are always present in the response (never `null`); loading states are communicated via HTTP status, not missing fields. | backend `vaultEndpoints.ts` |
+
+### 5.2 Backend → Contracts assumptions
+
+| # | Assumption | Where enforced |
+|---|-----------|----------------|
+| B1 | The contract emits a `deposit` event with `(user, amount, shares)` fields for every successful deposit. The backend indexer depends on this shape. | `eventPollingService.ts` event parser, `contracts/vault/src/lib.rs` |
+| B2 | The contract emits a `withdraw` event for completed withdrawals and a `pndwdraw` event when a large-withdrawal timelock is created. | `eventPollingService.ts`, contract `withdraw` / `execute_withdrawal` |
+| B3 | Contract function calls revert with typed `VaultError` codes. The backend maps these error codes to HTTP error responses. | `sorobanClient.ts`, [Error Code Catalog](./api/ERROR_CODE_CATALOG.md) |
+| B4 | The contract's `total_assets()` and `total_shares()` view functions are always consistent (no in-flight drift between the two). The backend reconciliation job assumes atomic updates. | `positionReconciliationJob.ts`, contract storage layout |
+| B5 | The contract admin address is a multi-sig or governance-controlled key. The backend does not hold or rotate this key — it is out of scope for backend ownership. | Deployment config, `@YieldVault-RWA/contracts-maintainers` |
+| B6 | Large-withdrawal timelocks are 24 hours. The backend's `withdrawalDailyLimit` middleware and retry logic is calibrated to this window. | `middleware/withdrawalDailyLimit.ts`, contract `LARGE_WITHDRAWAL_DELAY` constant |
+
+### 5.3 Frontend → Contracts assumptions (direct RPC path)
+
+| # | Assumption | Where enforced |
+|---|-----------|----------------|
+| C1 | `simulate_transaction` returns a fee estimate and the `shares_to_mint` (deposit) or `assets_to_return` (withdrawal) before the user signs. The frontend shows this preview. | `lib/vaultApi.ts` simulation step, `components/TransactionConfirmationModal.tsx` |
+| C2 | The contract enforces `min_deposit` on-chain. The frontend validates locally first (form schema) but treats a contract `BelowMinimumDeposit` error as the authoritative rejection. | `forms/schemas/depositFormSchema.ts`, `lib/errorMappers.ts` |
+| C3 | The vault contract ID is configured via `VITE_VAULT_CONTRACT_ID`. If this env var is missing or wrong, all transactions will fail silently. Frontend startup must validate this env var. | `frontend/src/config/network.ts`, [ENV Variable Matrix](./ENV_VARIABLE_MATRIX.md) |
+| C4 | The USDC token is an SEP-0041 Stellar Asset Contract (SAC). The frontend calls its `approve` function before depositing. If the allowance is already sufficient, the approve step is skipped. | `hooks/useTokenAllowance.ts`, `hooks/useVaultMutations.ts` |
+| C5 | Network passphrase (`VITE_STELLAR_NETWORK_PASSPHRASE`) must match the network the contract was deployed to. A mismatch produces invalid transaction signatures. | `frontend/src/config/network.ts`, `NetworkMismatchGuideModal.tsx` |
+
+### 5.4 Backend → Infrastructure assumptions
+
+| # | Assumption | Where enforced |
+|---|-----------|----------------|
+| I1 | PostgreSQL is available and migrated before the backend starts. A failed DB connection at startup causes the backend to exit (not silently degrade). | `database.ts`, `SERVICE_DEPENDENCY_MATRIX.md` |
+| I2 | Redis is available for rate limiting and idempotency. If Redis is unavailable, the backend falls back to in-memory limits (degraded, not offline). | `rateLimiter.ts` fallback logic |
+| I3 | The Soroban RPC node is reachable at `STELLAR_RPC_URL`. Unavailability triggers the circuit breaker in `circuitBreaker.ts`; the backend continues serving cached/DB-backed responses. | `circuitBreaker.ts`, `sorobanClient.ts` |
+| I4 | Database migrations are applied before the backend API is exposed. Running a new backend image against an un-migrated schema is an error condition covered in the [Deployment Checklist](./DEPLOYMENT_CHECKLIST.md). | `backend/prisma/`, `DEPLOYMENT_CHECKLIST.md` |

+# Vault Accounting Invariants (Issue #1166)
+
+This document is the operator-facing specification for the contract-level
+total-supply and share-price checks enforced by
+`contracts/vault/src/invariants.rs`.
+
+The vault persists `VaultState` only after these checks succeed. A future
+change to deposit, withdraw, yield, or share math must keep them true.
+
+## Canonical state
+
+Let \(T_S\) = `VaultState.total_shares` and \(T_A\) = `VaultState.total_assets`.
+Share price is scaled by \(10^{18}\):
+
+\[
+P(T_A, T_S) =
+\begin{cases}
+0 & \text{if } T_S = 0 \\
+\left\lfloor T_A \cdot 10^{18} / T_S \right\rfloor & \text{if } T_S > 0
+\end{cases}
+\]
+
+## Invariants
+
+| ID | Statement | Failure |
+| --- | --- | --- |
+| I1 | \(T_S \ge 0\) | `VaultError::MathOverflow` |
+| I2 | \(T_A \ge 0\) | `VaultError::MathOverflow` |
+| I3 | If \(T_S > 0\) then \(T_A > 0\) (no unbacked shares) | `VaultError::MathOverflow` |
+| I4 | If \(T_S = 0\) then \(P = 0\) | `VaultError::MathOverflow` |
+| I5 | If \(T_S > 0\) then \(P = \lfloor T_A \cdot 10^{18} / T_S \rfloor\) and \(P > 0\) | `VaultError::MathOverflow` |
+
+`MathOverflow` is reused because the Soroban error enum is capped at 50 cases.
+Integrators should treat it as "accounting assumption broken" when it fires
+from a deposit/withdraw/yield path that is not a genuine arithmetic overflow.
+
+## Allowed edge case
+
+\(T_A > 0\) with \(T_S = 0\) is allowed (donated / pre-deposit yield). The next
+deposit mints 1:1. Unbacked shares (\(T_S > 0\), \(T_A = 0\)) are never allowed.
+
+## Where they are checked
+
+`YieldVault::persist_accounting_state` runs the checks before writing
+`DataKey::State` on:
+
+- `deposit` / `gasless_deposit` / `batch_deposit`
+- `withdraw` / queued-liquidity withdraw
+- `accrue_yield` / `report_benji_yield`
+
+## Tests
+
+- Unit: `contracts/vault/src/invariants.rs` (violation snapshots)
+- Regression: `contracts/vault/src/invariant_tests.rs`
+- Formal: `docs/FORMAL_VERIFICATION_ACCOUNTING.md`

+### 5.1 Troubleshooting flows for common contract failures
+
+These are the most common operator and integrator failure patterns and the actions that
+restore normal behavior.
+
+#### A. Deposit fails with `InvalidAmount`, `MinDepositNotMet`, or `ExceedsUserCap`
+
+Typical symptoms:
+- deposit amount is `0`, negative, or rounds to zero shares
+- a user tries to deposit less than the configured minimum
+- the per-user cap has been reached
+
+Likely causes:
+- incorrect amount formatting or negative value in the wallet transaction
+- too-small stake relative to `min_deposit`
+- the vault has a strict user cap enabled for the current account
+
+Recovery:
+1. Confirm the value is positive and in the smallest denomination expected by the vault.
+2. Check the configured minimum deposit and user cap before resubmitting.
+3. Retry with a larger amount or after a new cap/window is available.
+
+#### B. Withdrawal or timelocked action stalls with `TimelockNotExpired`, `NoPendingWithdrawal`, or `WithdrawalCooldownActive`
+
+Typical symptoms:
+- withdraw is simulated successfully but cannot execute immediately
+- a large withdrawal is queued and requires a later execution step
+- a deposit cooldown is still active after a recent transaction
+
+Likely causes:
+- the large-withdrawal timelock has not elapsed yet
+- the user never queued the pending withdrawal or used the wrong action sequence
+- a recent deposit is still within the configured cooldown window
+
+Recovery:
+1. Wait until the required timelock or cooldown has elapsed.
+2. Re-check the pending action state before calling `execute_withdrawal` or retrying.
+3. Re-run the correct queue/execute sequence rather than repeating the original request.
+
+#### C. Strategy deployment or liquidity errors (`LiquidityBufferNotMet`, `InsufficientLiquidity`, `StrategyNotConfigured`, `UnauthorizedStrategy`)
+
+Typical symptoms:
+- a strategy allocation or rebalance is rejected
+- vault liquidity is insufficient to satisfy a request
+- the caller is using the wrong strategy address or a strategy is not enabled
+
+Likely causes:
+- idle liquidity is below the configured buffer
+- a strategy address is not configured or has not been whitelisted
+- the caller is not the strategy that the vault expects for the action
+
+Recovery:
+1. Verify the strategy is configured and whitelisted.
+2. Reduce requested allocation or wait for liquidity to accumulate.
+3. Ensure the operator or wallet address matches the authorized strategy/relayer.
+
+#### D. Governance and emergency actions (`GovernanceThresholdNotMet`, `DisputeWindowActive`, `ProposalCancelled`, `RescueUnauthorized`)
+
+Typical symptoms:
+- action reaches the contract but governance approvals are insufficient
+- an emergency proposal cannot be confirmed before the dispute window closes
+- rescue authorization is rejected for a non-approver or invalid destination
+
+Likely causes:
+- required signer set is not configured or quorum is not reached
+- a proposal is still in dispute or was cancelled before confirmation
+- rescue parameters are invalid, such as a destination equal to the vault itself
+
+Recovery:
+1. Check signer approvals and quorum thresholds before resubmitting governance actions.
+2. Wait for the dispute window to close or cancel the proposal correctly.
+3. Use only valid emergency approvers and permitted destination addresses.
+
+#### E. Batch and relayer failure (`BatchTooLarge`, `RelayerNotAuthorized`, `RapidAction`)
+
+Typical symptoms:
+- batch deposit fails even though individual deposits succeed
+- only a whitelisted relayer can submit batch entries
+- a deposit and withdrawal happen in the same ledger and are rejected
+
+Likely causes:
+- batch size exceeds the configured limit
+- the caller is not the relayer configured for the vault
+- the same ledger contains conflicting actions for the same user or vault state
+
+Recovery:
+1. Split large deposits into multiple smaller batches.
+2. Use the configured relayer and verify the relayer is authorized.
+3. Space out actions across ledger boundaries or retry after the conflicting ledger closes.
+
+### 5.2 Typical misuse and recovery patterns
+
+The following examples capture common mistakes and what to do instead:
+
+1. Misuse: sending a negative or zero `amount` to `deposit`.
+   - Result: `VaultError::InvalidAmount`.
+   - Recovery: send a positive amount greater than the minimum deposit requirement.
+
+2. Misuse: trying to claim a withdrawal before the timelock expires.
+   - Result: `VaultError::TimelockNotExpired`.
+   - Recovery: wait for the queued action to mature, then call the execution step.
+
+3. Misuse: using an unapproved relayer on batch deposits.
+   - Result: `VaultError::RelayerNotAuthorized`.
+   - Recovery: configure or use an approved relayer and re-submit the batch.
+
+4. Misuse: resubmitting the same idempotency key with a different payload.
+   - Result: API `409 Conflict` at the backend layer.
+   - Recovery: regenerate the idempotency key or replay the exact same payload.
+
+5. Misuse: calling emergency rescue with a disallowed destination or unauthorized approver.
+   - Result: `VaultError::RescueUnauthorized`.
+   - Recovery: use only approved approvers and valid vault-safe destination addresses.

+# API Rate Limiting
+
+Sensitive and public API traffic is protected by independent limits. Limits are
+applied per client IP and, where an identity is available, per user identity.
+Authenticated vault mutations therefore cannot bypass protection by changing
+networks, and one noisy client cannot exhaust another user's quota.
+
+## Default tiers
+
+| Tier | Default limit | Scope |
+|------|---------------|-------|
+| Auth | 5 requests/minute | IP and wallet identity |
+| Reads | 60 requests/minute | IP/request identity |
+| Writes | 10 requests/minute | Request identity |
+| Deposits/withdrawals | 10 requests/minute | IP and wallet identity |
+| Admin | 20 requests/minute | API-key tenant and IP |
+
+Operators can override limits with the `RATE_LIMIT_*`, `DEPOSITS_RATE_LIMIT_*`,
+and `API_RATE_LIMIT_*` environment variables. Redis is used when configured;
+the service falls back to in-memory enforcement when Redis is unavailable.
+
+## 429 response
+
+```json
+{
+  "error": "Rate limit exceeded",
+  "status": 429,
+  "code": "RATE_LIMIT_EXCEEDED",
+  "message": "Too many requests. Please try again in 42 seconds.",
+  "retryable": true,
+  "retryAfter": 42,
+  "retryAfterSeconds": 42
+}
+```
+
+The `Retry-After` response header contains the number of seconds to wait.
+Adaptive abuse protection may return `code: "ADAPTIVE_THROTTLE"` with the same
+retry fields.
+
+## Client behavior
+
+Honor `Retry-After` and do not retry immediately. Use exponential backoff with
+jitter, stop retrying when the server continues returning 429, and avoid retrying
+non-idempotent mutations unless the API's idempotency mechanism is in use.
+Display a temporary unavailable state rather than treating throttling as a
+permanent authentication failure.

+# Performance Fee Switch: Governance Process
+
+**Issue:** #1230  
+**Status:** Implemented  
+
+## Overview
+
+The performance fee switch allows vault administrators to redirect a portion of strategy yield to a performance incentive pool. This document describes the governance process for activating and managing this feature.
+
+## Configuration Parameters
+
+| Parameter | Type | Range | Default | Description |
+|-----------|------|-------|---------|-------------|
+| `performance_fee_bps` | i128 | 0–10000 | 0 | Fee in basis points on yield above high-water mark |
+| `performance_incentive_pool` | Address | — | None | Destination address for performance fees |
+| `performance_fee_enabled` | bool | — | false | Master toggle for the fee switch |
+
+## Activation Process
+
+### Step 1: Configure the Incentive Pool
+
+```
+Admin calls: set_performance_incentive_pool(pool_address)
+```
+
+The pool address must be a valid Stellar address. This is typically a DAO treasury, team multisig, or dedicated incentive contract.
+
+### Step 2: Set the Performance Fee Rate
+
+```
+Admin calls: set_performance_fee_bps(bps)
+```
+
+The fee is expressed in basis points (0–10000). For example:
+- 100 bps = 1% of yield above HWM
+- 500 bps = 5% of yield above HWM
+- 1000 bps = 10% of yield above HWM
+
+**Recommendation:** Start with a conservative rate (100–200 bps) and adjust based on performance.
+
+### Step 3: Enable the Fee Switch
+
+```
+Admin calls: set_performance_fee_enabled(true)
+```
+
+This will fail if the incentive pool has not been configured.
+
+## How It Works
+
+1. **Yield reporting:** When a strategy reports yield (via `report_benji_yield` or `accrue_korean_debt_yield`), the contract checks if the performance fee switch is enabled.
+
+2. **High-water mark comparison:** The yield amount is compared against the strategy's high-water mark. Only yield ABOVE the high-water mark is subject to the performance fee.
+
+3. **Fee calculation:** `perf_fee = yield_above_hwm × perf_fee_bps / 10_000`
+
+4. **Transfer:** The performance fee is transferred to the incentive pool address.
+
+5. **Event emission:** A `pperffee` event is emitted with the fee amount and yield above HWM.
+
+## Important Notes
+
+- **No timelock required:** Unlike protocol fee changes, the performance fee switch can be toggled immediately. This is because it affects only new yield, not existing balances.
+- **Protocol fee applies first:** The standard protocol fee (`fee_bps`) is deducted before the performance fee. The performance fee is calculated on the net yield after protocol fees.
+- **Watermark-based:** Only yield above the high-water mark is subject to the fee. This means early performance that recovers previous losses is not charged.
+- **Admin-only:** All configuration changes require admin authorization.
+
+## Events
+
+| Event | Symbol | Data | Description |
+|-------|--------|------|-------------|
+| Pool set | `pperfpool` | (pool_address) | Incentive pool address was changed |
+| Fee rate changed | `pperfchg` | (bps) | Performance fee rate was updated |
+| Toggle changed | `pperftog` | (enabled) | Fee switch was toggled |
+| Fee charged | `pperffee` | (strategy, amount, yield_above_hwm) | Performance fee was collected |
+
+## Example Governance Proposal
+
+```
+Title: Activate Performance Fee for Strategy Incentives
+Description: Enable a 2% performance fee on yield above the high-water mark,
+             directing fees to the team incentive pool for strategy development.
+
+Actions:
+1. set_performance_incentive_pool(TTEAM_MULTISIG_ADDRESS)
+2. set_performance_fee_bps(200)
+3. set_performance_fee_enabled(true)
+
+Expected Impact:
+- 2% of incremental yield directed to strategy development fund
+- No impact on existing depositor balances
+- Only applies to new yield above previous peak
+```
+
+## Risk Considerations
+
+1. **Admin key compromise:** A compromised admin key could set the fee to 100% (10000 bps). Mitigation: use multi-sig for admin, monitor events.
+2. **No depositor governance:** Performance fee changes don't require depositor vote. Mitigation: transparent configuration, event monitoring.
+3. **Strategy gaming:** An admin could manipulate watermarks to avoid fees. Mitigation: watermarks are cumulative and cannot be lowered.
+
+## Future Enhancements
+
+- Governance vote requirement for fee changes above a threshold
+- Maximum fee cap enforced at the contract level
+- Automatic fee distribution to multiple recipients
+- Time-weighted average performance fee (reduce gaming)

+
+### Scenario A: Smart Contract Accounting Discrepancy / Fund Safety Threat
+- **Symptoms**: `total_assets()` or share price deviates from expected formula; deposit/withdraw events revert on-chain; unauthorized asset movement.
+- **Immediate Action**:
+  1. Incident Commander & Contracts Lead immediately trigger emergency circuit breaker:
+     ```bash
+     soroban contract invoke \
+       --id <VAULT_CONTRACT_ID> \
+       --source admin \
+       --network <network> \
+       -- set_pause --paused true
+     ```
+  2. Page Security Lead if unauthorized access is suspected.
+  3. Freeze indexer and backend ingestion if needed: `SET INDEXER_PAUSED=true`.
+
+### Scenario B: Stellar RPC Provider Failure / Extreme Latency
+- **Symptoms**: Horizon/Soroban RPC requests timing out (> 1500 ms); `504 Gateway Timeout` on contract calls; indexer falling behind ledger head.
+- **Immediate Action**:
+  1. Switch to secondary RPC provider via configuration or load balancer:
+     ```bash
+     # Update backend environment variable or Consul config
+     export STELLAR_RPC_URL="https://backup-rpc.stellar.org"
+     systemctl reload yieldvault-backend
+     ```
+  2. See [`docs/runbooks/RPC_FAILOVER.md`](./RPC_FAILOVER.md) for full failover procedures.
+
+### Scenario C: Transaction Submission & Delivery Failures
+- **Symptoms**: Transactions returning `TxFailed`, fee insufficient errors, or stuck in transaction queue.
+- **Immediate Action**:
+  1. Check network base fee and adjust fee bump multiplier.
+  2. Clear stale pending transaction intents from memory/redis queue.
+  3. Verify sequence numbers and account sequence synchronization.
+
+### Scenario D: Database Migration Drift / Corruption Post-Deploy
+- **Symptoms**: Backend crashing with Prisma schema mismatch; foreign key violation spikes; unrecoverable write errors.
+- **Immediate Action**:
+  1. Stop incoming API traffic to backend.
+  2. Execute migration rollback SQL:
+     ```bash
+     psql $DATABASE_URL -f backend/prisma/migrations/<target_migration>/rollback.sql
+     ```
+  3. Revert backend binary/container to previous release commit.
+
+### Scenario E: Frontend Broken Bundle / Chunk Hydration Failures
+- **Symptoms**: Blank page on user visits; unhandled JavaScript runtime exceptions in Sentry; CSS/layout corruption.
+- **Immediate Action**:
+  1. Trigger instant rollback in hosting platform:
+     ```bash
+     vercel rollback --token $VERCEL_TOKEN
+     ```
+  2. Purge Cloudflare / CDN edge cache for frontend routes.
+
+---
+
+## 3. Rollback Activation Conditions
+
+The Incident Commander MUST authorize a rollback if any of the following conditions are met:
+
+1. **Unresolved Health Probe Failure**: Backend `/health` or `/ready` failing for > 2 consecutive minutes after deployment.
+2. **Critical Error Budget Exhaustion**: HTTP 5xx error rate > 5% on tier-critical API endpoints (`/api/v1/vault/*`, `/api/v1/transactions/*`) for > 5 minutes.
+3. **Smart Contract Invariant Violation**: Any state corruption, math inconsistency in share pricing, or failure in deposit/withdraw execution.
+4. **Data Integrity Failure**: Database migrations producing data loss or query failures that cannot be fixed within 15 minutes.
+5. **Security Vulnerability**: Critical vulnerability discovered in newly deployed code that exposes funds, user data, or API authorization keys.
+
+---
+
+## 4. Step-by-Step Rollback Operations
+
+### 4.1 Smart Contracts Rollback
+
+#### Option 1: WASM Hash Downgrade (In-place contract rollback)
+When the contract proxy or upgrade pattern allows WASM replacement:
+```bash
+# 1. Ensure vault remains paused
+soroban contract invoke \
+  --id <VAULT_CONTRACT_ID> \
+  --source admin \
+  --network <mainnet|testnet> \
+  -- set_pause --paused true
+
+# 2. Revert to previous known-good WASM hash
+soroban contract invoke \
+  --id <VAULT_CONTRACT_ID> \
+  --source admin \
+  --network <mainnet|testnet> \
+  -- upgrade --new_wasm_hash <PREVIOUS_STABLE_WASM_HASH>
+
+# 3. Verify contract version and invariant state
+soroban contract invoke --id <VAULT_CONTRACT_ID> --network <network> -- version
+soroban contract invoke --id <VAULT_CONTRACT_ID> --network <network> -- total_assets
+
+# 4. Unpause once verified
+soroban contract invoke \
+  --id <VAULT_CONTRACT_ID> \
+  --source admin \
+  --network <network> \
+  -- set_pause --paused false
+```
+
+#### Option 2: Fallback Contract Address Re-pointing
+If in-place WASM upgrade is damaged:
+1. Update `VAULT_CONTRACT_ID` in backend and frontend environment configs to point to the previous immutable contract address.
+2. Trigger backend redeploy and frontend CDN redeployment.
+
+### 4.2 Backend Service Rollback
+
+```bash
+# 1. Stop active backend process / container
+sudo systemctl stop yieldvault-backend
+
+# 2. Checkout previous stable release commit/tag
+cd /app/yieldvault-backend
+git checkout <PREVIOUS_RELEASE_TAG>
+
+# 3. If database migration was executed, apply down-migration
+psql $DATABASE_URL -f prisma/migrations/<FAILED_MIGRATION>/rollback.sql
+
+# 4. Rebuild & start service
+npm ci --production
+npm run build
+sudo systemctl start yieldvault-backend
+
+# 5. Verify local health
+curl -f http://localhost:3000/health
+curl -f http://localhost:3000/ready
+```
+
+### 4.3 Frontend Rollback
+
+```bash
+# Vercel Instant Rollback
+vercel rollback --token=$VERCEL_TOKEN --yes
+
+# Or re-deploy pre-built previous artifact
+vercel deploy --prebuilt --prod --token=$VERCEL_TOKEN
+
+# Clear CDN Edge Caches
+curl -X POST "https://api.cloudflare.com/client/v4/zones/$CF_ZONE_ID/purge_cache" \
+  -H "Authorization: Bearer $CF_API_TOKEN" \
+  -H "Content-Type: application/json" \
+  --data '{"purge_everything":true}'
+```
+
+### 4.4 Database Disaster Recovery (Point-in-Time Recovery)
+If database state was corrupted:
+1. Stop backend writers.
+2. Initiate Point-in-Time Recovery (PITR) to timestamp `T_deploy - 5 minutes` via AWS RDS / Supabase / GCP Cloud SQL console.
+3. Validate row counts and table integrity.
+4. Point backend to restored database instance and restart.
+

-## 2. Deployment Rollback Procedure
+## 6. Post-Rollback Verification & Sign-Off
 
-### Phase A: Immediate Emergency Pause (Circuit Breaker)
-If the issue affects money movement or contract state, pause the contracts immediately.
+Before resolving the incident and reopening public services, verify:
 
-1. **Pause YieldVault Contracts:**
-   ```bash
-   # Run pause script or call pause method via CLI
-   cargo run -p scripts -- bin/pause_vault --network mainnet
+- [ ] `GET /health` returns HTTP 200 `healthy`.
+- [ ] `GET /ready` returns HTTP 200 `ready: true`.
+- [ ] Vault contract `paused()` is `false` (if deliberately unpaused) and share pricing math is verified.
+- [ ] Test deposit and withdrawal executed successfully on staging/mainnet canary account.
+- [ ] Sentry error rates returned to pre-incident baseline for > 10 minutes.
+- [ ] Public status page marked as **Resolved**.
+- [ ] Postmortem issue scheduled (within 48 hours for Sev0/Sev1) per [`docs/postmortem-playbook.md`](../postmortem-playbook.md).

+# Encryption Review — Data at Rest & in Transit
+
+**Last Updated:** 2026-08-26
+**Related Issue:** [#1161](https://github.com/Junirezz/YieldVault-RWA/issues/1161) — Add encryption review for sensitive data at rest and in transit
+**Maintained By:** Backend & Security reviewers
+
+---
+
+## Purpose
+
+This document satisfies the acceptance criteria of Issue #1161:
+
+- Review storage of secret and PII-like data
+- Validate TLS or secure transport settings
+- Document encryption responsibilities by service
+- Flag unsafe data handling in review checklists
+
+It records the **current, verified state** of the codebase (file/line references throughout) — it is a snapshot, not a target architecture. Findings that describe gaps are flagged explicitly in [§4](#4-findings). This document does not replace [`docs/SECURITY_CHECKLIST.md`](../SECURITY_CHECKLIST.md) (smart-contract vulnerability classes) or [`docs/PRODUCTION_SECURITY_CHECKLIST.md`](../PRODUCTION_SECURITY_CHECKLIST.md) (keys/CORS/logging hardening plan) — it complements both and cross-references them where relevant.
+
+For the companion PR-time checklist, see [`.github/SECURITY_REVIEW_CHECKLIST.md`](../../.github/SECURITY_REVIEW_CHECKLIST.md).
+
+---
+
+## 1. Encryption Responsibilities by Service
+
+| Layer / Service | Sensitive data it handles | At-rest protection | In-transit protection | Owner | Notes |
+|---|---|---|---|---|---|
+| **Frontend (SPA)** | Wallet address (public), UI preferences, session timestamps. No private keys or JWTs found in browser storage. | N/A — nothing secret is persisted client-side | HTTPS via Vercel/CDN TLS termination for the SPA; REST calls to the backend and Soroban RPC calls over HTTPS | `@frontend-maintainers` | Transaction signing is delegated entirely to the Freighter wallet extension; private keys never enter application code (`useWalletConnection.ts`, `walletSession.ts`). See F5 for missing HSTS/CSP headers. |
+| **Backend API (Express)** | `JWT_SECRET`, `WALLET_ACTION_HMAC_SECRET`, API keys, scoped admin tokens, admin action receipts, webhook signing secrets | Secrets held only in process env; persisted tokens/keys are one-way hashed (SHA-256/HMAC) before storage, never in plaintext | TLS is expected to terminate in front of the process (proxy/CDN); no HSTS/security headers are set by the app itself (F3) | `@backend-maintainers` | `JWT_SECRET` is fail-fast validated in production (`backend/src/auth.ts`); `WALLET_ACTION_HMAC_SECRET` is not (F4). |
+| **PostgreSQL (raw `pg` pool)** | Transactions, APY snapshots, webhook config, rate-limit backing data | Managed Postgres at-rest encryption (infra-level, outside this repo's code) | `sslmode=require` is documented in `backend/.env.production.example` by convention, but not enforced in code (F2) | `@backend-maintainers` / DevOps | `backend/src/database.ts` — `PostgresDatabasePool` builds `pg.Pool` from the connection string with no explicit `ssl` option. |
+| **Prisma-managed store** | Hashed API keys, hashed scoped admin tokens, wallet aliases, admin audit/receipt records | **Silently falls back to a local SQLite file (`file:./dev.db`) whenever `DATABASE_URL` is a `postgres://`/`mysql://` URL** — see F1 | N/A (local file access, not networked) while the SQLite fallback is active | `@backend-maintainers` | `backend/prisma/schema.prisma` declares `provider = "sqlite"`; `backend/src/prisma.ts` explicitly falls back rather than erroring. Contradicts [ADR-001](../architecture-decision-records/ADR-001-use-prisma-for-database-access.md) ("Prisma for PostgreSQL access"). Highest-priority finding in this review. |
+| **Redis (cache / rate-limit / token store)** | Refresh tokens, rate-limit counters, idempotency keys | In-memory; falls back to an in-process LRU cache when `REDIS_URL` is unset (documented behavior, not itself a gap) | Depends entirely on the `REDIS_URL` scheme (`redis://` vs `rediss://`); not validated or enforced in code | `@backend-maintainers` | `backend/src/redisCache.ts`, `backend/src/rateLimiter.ts`, `backend/src/auth.ts` |
+| **Contracts (Soroban / Rust)** | On-chain vault state, admin address, oracle heartbeat bounds. No off-chain secrets or API keys. | On-chain ledger, governed by the Stellar network's own security model | Soroban RPC over HTTPS (`STELLAR_RPC_URL`) | `@contracts-maintainers` | Confirmed no secret/private-key handling in `contracts/vault`, `contracts/mock-strategy`, `contracts/share-price-math`. |
+| **CI/CD (GitHub Actions)** | Deploy tokens (Vercel, Sentry), staging/prod DB URLs, Soroban secret keys | GitHub Actions encrypted secrets store; referenced only via `secrets.*` context, never hardcoded | HTTPS to GitHub/Vercel/Sentry | `@backend-maintainers` / `@frontend-maintainers` | `.github/workflows/secret-scanning.yml` runs `gitleaks` on every push/PR and daily on schedule; no plaintext credentials found in any workflow. |
+| **Webhook delivery (outbound)** | Subscriber event payloads | N/A — in-flight only | HTTPS POST, HMAC-SHA256 signed payloads (`webhookDelivery.ts`) | `@integrations-owner` | Existing, solid control — no changes recommended. |
+
+---
+
+## 2. Data at Rest
+
+- **Secret loading**: all secrets are read from `process.env` (populated from `.env` files locally, GitHub Actions secrets in CI, and platform env vars in deployed environments). There is no KMS/HSM/Secrets Manager integration in application code today — this matches the gap already tracked in [`docs/PRODUCTION_SECURITY_CHECKLIST.md`](../PRODUCTION_SECURITY_CHECKLIST.md).
+- **Hashing over encryption for tokens**: API keys, scoped admin tokens, admin receipts, and webhook secrets are stored as SHA-256/HMAC digests, never in plaintext (`backend/src/middleware/apiKeyAuth.ts:88,155`, `backend/src/scopedAdminTokens.ts`, `backend/src/adminReceipt.ts`). This is appropriate for high-entropy generated tokens (not user passwords, so bcrypt/argon2 is not required here).
+- **PII in the schema**: `backend/prisma/schema.prisma` stores wallet addresses (pseudonymous, not directly PII) and no plaintext secret/PII columns were found. See [`docs/DATA_RETENTION_DELETION_POLICY.md`](../DATA_RETENTION_DELETION_POLICY.md) for retention periods per data category.
+- **Log redaction**: `backend/src/auditRedaction.ts` regex-redacts secret/token/password/private-key/mnemonic patterns before audit logging — a real, working control.
+- **Prisma/SQLite fallback**: see F1 below — this is the most consequential at-rest finding in this review.
+
+## 3. Transport / TLS Validation
+
+- **CORS**: an explicit origin-allowlist middleware exists (`backend/src/middleware/cors.ts`, driven by `CORS_ALLOWED_ORIGINS`) — validated and working.
+- **Database TLS**: `backend/.env.production.example` documents `?sslmode=require` in the example `DATABASE_URL`, but `backend/src/database.ts` does not pass an explicit `ssl` option to `pg.Pool` and does not validate the connection string's `sslmode` at startup — enforcement is convention-only (F2).
+- **API transport headers**: no `helmet` (or equivalent) dependency exists in `backend/package.json`; the Express app sets no HSTS/CSP/security headers itself (F3). Auth uses `Authorization: Bearer` headers exclusively — no cookies are set, so `Secure`/`HttpOnly`/`SameSite` flags are not applicable to this service.
+- **Frontend headers**: `frontend/vercel.json` sets `X-Content-Type-Options`, `X-Frame-Options`, `X-XSS-Protection`, `Referrer-Policy`, and `Permissions-Policy`, but no `Strict-Transport-Security` or `Content-Security-Policy` (F5), despite `frontend/SECURITY_PATTERNS.md` documenting a CSP that was never wired into the deploy config.
+- **Soroban RPC**: both frontend (`VITE_SOROBAN_RPC_URL`) and backend (`STELLAR_RPC_URL`) default to `https://` RPC endpoints; no plaintext `http://` RPC or API URLs were found in either codebase.
+- **Wallet-action verification**: `backend/src/walletSignature.ts` supports two modes — `stellar` (Ed25519 signature verification via `@stellar/stellar-base`, intended for production) and `hmac` (development/test only, using `WALLET_ACTION_HMAC_SECRET`). See F4 for the missing production guard on this mode selection.
+
+---
+
+## 4. Findings
+
+Findings are flagged, not fixed, per this review's scope. Severity reflects blast radius if the current behavior is relied on in production, not likelihood.
+
+### F1 — High: Prisma-managed secrets may persist to a local SQLite file, not the managed Postgres database
+
+- **Evidence**: `backend/prisma/schema.prisma:8-11` declares `provider = "sqlite"`, `url = "file:./dev.db"`. `backend/src/prisma.ts:16-43` explicitly returns `undefined` (falling back to the schema-declared SQLite file) whenever `DATABASE_URL` starts with `postgres://` or `mysql://`, by design — to avoid a hard crash rather than to intentionally route data to SQLite.
+- **Impact**: every model Prisma manages — including hashed API keys, hashed scoped admin tokens, wallet aliases, and admin audit/receipt records — can end up persisted to a local, unencrypted `dev.db` file on the application host instead of the TLS-protected, infra-encrypted Postgres instance referenced everywhere else in this document and in [ADR-001](../architecture-decision-records/ADR-001-use-prisma-for-database-access.md).
+- **Recommendation**: align the Prisma datasource provider with the actual production database (`postgresql`) and fail startup loudly if `DATABASE_URL` is unset or unreachable, instead of silently degrading to a local file.
+
+### F2 — Medium: Postgres TLS (`sslmode=require`) is documented, not enforced
+
+- **Evidence**: `backend/src/database.ts` builds `pg.Pool` from `connectionString` alone; `.env.production.example:27-28` documents `sslmode=require` but nothing in code validates it's present, and `.env.example` has no `sslmode` at all.
+- **Recommendation**: validate `sslmode=require` (or pass an explicit `ssl` option) at startup when `NODE_ENV=production`, and fail fast if it's missing.
+
+### F3 — Medium: No security-header middleware (helmet/HSTS/CSP) on the backend API
+
+- **Evidence**: `helmet` is not a dependency in `backend/package.json`; no equivalent header middleware exists in `backend/src`.
+- **Recommendation**: add `helmet` (or equivalent) with HSTS at minimum, or explicitly document that TLS termination and header hygiene are owned entirely by the fronting proxy/CDN and are out of this repo's scope.
+
+### F4 — Low: `WALLET_ACTION_HMAC_SECRET` has no production fail-fast validation
+
+- **Evidence**: `backend/src/walletSignature.ts:15-18` falls back from `WALLET_ACTION_HMAC_SECRET` → `JWT_SECRET` → a hardcoded dev string, with no equivalent to `auth.ts`'s `assertJwtSecretValid()`. This only matters when `WALLET_SIGNATURE_MODE=hmac`; production is documented to use `stellar` (Ed25519) mode instead.
+- **Recommendation**: add the same startup validation used for `JWT_SECRET`, or explicitly forbid `WALLET_SIGNATURE_MODE=hmac` when `NODE_ENV=production`.
+
+### F5 — Low: Frontend is missing HSTS/CSP headers despite having a documented policy
+
+- **Evidence**: `frontend/vercel.json` sets several security headers but no `Strict-Transport-Security` or `Content-Security-Policy`; `frontend/SECURITY_PATTERNS.md` documents a CSP that isn't wired into the deploy config.
+- **Recommendation**: add the documented CSP and an HSTS header to `frontend/vercel.json`.
+
+### F6 — Informational: `docs/PRODUCTION_SECURITY_CHECKLIST.md` item 1 is stale
+
+- **Evidence**: that document states API keys use an "in-memory `API_KEYS` Map." `backend/src/middleware/apiKeyAuth.ts:71-110` is already Prisma/DB-backed with SHA-256-hashed keys, roles, and tenant scoping (subject to the F1 SQLite-fallback caveat above).
+- **Recommendation**: update that checklist item in a follow-up PR to avoid contributors re-doing already-completed work.

+## 5. Relationship to Existing Security Documentation
+
+| Document | Scope | How this review relates |
+|---|---|---|
+| [`docs/SECURITY_CHECKLIST.md`](../SECURITY_CHECKLIST.md) | Smart-contract vulnerability classes (reentrancy, access control, gas/DoS) | Out of scope here — contracts hold no off-chain secrets (§1) |
+| [`docs/PRODUCTION_SECURITY_CHECKLIST.md`](../PRODUCTION_SECURITY_CHECKLIST.md) | Keys/secrets management plan, CORS, logging hygiene, operational controls | This review validates and updates several of its claims (see F6) and adds the TLS/at-rest findings (F1-F5) it didn't cover |
+| [`docs/DATA_RETENTION_DELETION_POLICY.md`](../DATA_RETENTION_DELETION_POLICY.md) | Retention periods and deletion workflows per data category | Defines *how long* data is kept; this review covers *how it's protected* while it exists |
+| [`docs/ENV_VARIABLE_MATRIX.md`](../ENV_VARIABLE_MATRIX.md) | Full env var reference per service | Source of truth for the secret/config variable names referenced throughout this review |
+| [`docs/api/AUTH_AND_TOKEN_GUIDE.md`](../api/AUTH_AND_TOKEN_GUIDE.md) | JWT/token issuance and lifecycle | Authoritative for the auth flow this review only summarizes |
+| [ADR-001](../architecture-decision-records/ADR-001-use-prisma-for-database-access.md) | Decision to use Prisma for PostgreSQL access | Currently contradicted by the live schema/config — see F1 |
+

+
+## 6. Review Cadence
+
+This review reflects the codebase as of the date above. Re-review when:
+
+- A new service, data store, or third-party integration is introduced
+- Any finding in §4 is resolved or its status changes

+### 5.4 Strategy Failure Behavior
+
+- Vaults treat strategy return data as untrusted input: the configured strategy must report the
+  vault's underlying asset address and a non-negative `total_value()`.
+- If a strategy returns a mismatched asset or a negative value, the vault aborts the operation with
+  `VaultError::UnauthorizedStrategy` or `VaultError::InvalidAmount` instead of continuing with
+  partial accounting.
+- When a strategy call itself reverts or fails to return a valid result, the transaction is aborted at
+  the call boundary; no state update is committed. This ensures malicious or partially implemented
+  strategy integrations fail predictably and do not silently distort vault share pricing.

+# Frontend Wallet, Theme, Form, and API Error Surface
+
+This note maps the implemented user-facing frontend surface to the modules that
+own each behavior.
+
+## Wallet connection persistence
+
+- `src/lib/walletConnectionState.ts` owns the typed connection reducer and wallet error classification.
+- `src/lib/walletSession.ts` persists the last provider, reconnect prompt flags, and the validated connected wallet address.
+- `src/App.tsx` restores the persisted address on load, updates it after successful connection, and clears it on disconnect.
+
+## Theme support
+
+- `src/context/PreferencesContext.tsx` resolves `dark`, `light`, and `system` preferences, applies `data-theme`, and persists the preference.
+- `src/components/ThemeToggle.tsx` exposes the header toggle.
+- `src/index.css` defines the dark default and `[data-theme='light']` CSS variables.
+
+## Real-time form validation
+
+- `src/forms/useForm.ts` validates on blur, revalidates touched fields while typing, and validates all fields on submit.
+- `src/forms/components/FormField.tsx`, `FormSelect.tsx`, and `FormTextarea.tsx` render inline errors with `aria-invalid` and `role="alert"`.
+- Deposit and withdrawal rules live in `src/forms/schemas/depositFormSchema.ts` and `withdrawFormSchema.ts`.
+
+## API error handling
+
+- `src/lib/api/error.ts` normalizes network, timeout, auth, HTTP, and invalid-response failures into `ApiError`.
+- `src/lib/api/client.ts` applies retry/correlation behavior and throws normalized `ApiError` instances.
+- `src/components/ApiStatusBanner.tsx` displays user-friendly API messages instead of raw backend objects.

+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+Form, as described in Section 3.1, and You must inform recipients of
+the Executable Form how they can obtain a copy of such Source Code
+Form by reasonable means in a timely manner, at a charge no more
+than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+License, or sublicense it under different terms, provided that the
+license for the Executable Form does not attempt to limit or alter
+the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.
+
+************************************************************************
+* *
+* 6. Disclaimer of Warranty *
+* ------------------------- *
+* *
+* Covered Software is provided under this License on an "as is" *
+* basis, without warranty of any kind, either expressed, implied, or *
+* statutory, including, without limitation, warranties that the *
+* Covered Software is free of defects, merchantable, fit for a *
+* particular purpose or non-infringing. The entire risk as to the *
+* quality and performance of the Covered Software is with You. *
+* Should any Covered Software prove defective in any respect, You *
+* (not any Contributor) assume the cost of any necessary servicing, *
+* repair, or correction. This disclaimer of warranty constitutes an *
+* essential part of this License. No use of any Covered Software is *
+* authorized under this License except under this disclaimer. *
+* *
+************************************************************************
+
+************************************************************************
+* *
+* 7. Limitation of Liability *
+* -------------------------- *
+* *
+* Under no circumstances and under no legal theory, whether tort *
+* (including negligence), contract, or otherwise, shall any *
+* Contributor, or anyone who distributes Covered Software as *
+* permitted above, be liable to You for any direct, indirect, *
+* special, incidental, or consequential damages of any character *
+* including, without limitation, damages for lost profits, loss of *
+* goodwill, work stoppage, computer failure or malfunction, or any *
+* and all other commercial damages or losses, even if such party *
+* shall have been informed of the possibility of such damages. This *
+* limitation of liability shall not apply to liability for death or *
+* personal injury resulting from such party's negligence to the *
+* extent applicable law prohibits such limitation. Some *
+* jurisdictions do not allow the exclusion or limitation of *
+* incidental or consequential damages, so this exclusion and *
+* limitation may not apply to You. *
+* *
+************************************************************************
+
+8. Litigation
+-------------
+
+Any litigation relating to this License may be brought only in the
+courts of a jurisdiction where the defendant maintains its principal
+place of business and such litigation shall be governed by laws of that
+jurisdiction, without reference to its conflict-of-law provisions.
+Nothing in this Section shall prevent a party's ability to bring
+cross-claims or counter-claims.
+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License
+---------------------------
+
+10.1. New Versions
+
+Mozilla Foundation is the license steward. Except as provided in Section
+10.3, no one other than the license steward has the right to modify or
+publish new versions of this License. Each version will be given a
+distinguishing version number.
+
+10.2. Effect of New Versions
+
+You may distribute the Covered Software under the terms of the version
+of the License under which You originally received the Covered Software,
+or under the terms of any subsequent version published by the license
+steward.
+
+10.3. Modified Versions
+
+If you create software not governed by this License, and you want to
+create a new license for such software, you may create and use a
+modified version of this License if you rename the license and remove
+any references to the name of the license steward (except to note that
+such modified license differs from this License).
+
+10.4. Distributing Source Code Form that is Incompatible With Secondary
+Licenses
+
+If You choose to distribute Source Code Form that is Incompatible With
+Secondary Licenses under the terms of this version of the License, the
+notice described in Exhibit B of this License must be attached.
+
