+# Configuration Types Reference
+# =============================================================================
+# 
+# REQUIRED vs OPTIONAL:
+# 
+#   REQUIRED
+#     Variables that must be set. Missing values will cause startup failure.
+#     Examples:
+#       - NODE_ENV (controls error handling and feature availability)
+#       - DATABASE_URL (connection to persistent storage)
+#       - STELLAR_RPC_URL (connection to blockchain)
+# 
+#   OPTIONAL
+#     Variables that may be omitted. Use defaults if not provided.
+#     Examples:
+#       - LOG_LEVEL (defaults to "info")
+#       - REDIS_CONNECT_TIMEOUT (defaults to 5000 ms)
+#       - CORS_ALLOWED_ORIGINS (uses env-specific defaults when unset)
+# 
+# CONFIGURATION TYPE VALIDATION:
+# 
+#   Enum Types (string choices)
+#     Values constrained to a predefined list of strings.
+#     Examples:
+#       - NODE_ENV: "development" | "test" | "production"
+#       - LOG_LEVEL: "debug" | "info" | "warn" | "error"
+#     Invalid values cause startup failure with clear error message.
+# 
+#   Integer Types (whole numbers)
+#     Values must be positive integers within optional bounds.
+#     Examples:
+#       - PORT: positive integer, range 1-65535
+#       - ORACLE_POLL_INTERVAL_MS: positive integer, range 5000-3600000
+#     Non-integer or out-of-range values cause startup failure.
+# 
+#   URL Types (connection strings)
+#     Values must be valid URLs with specific schemes.
+#     Examples:
+#       - DATABASE_URL: must use postgresql:// or postgres:// scheme
+#       - REDIS_URL: must use redis:// or rediss:// scheme
+#     Invalid URLs cause startup failure with clear error message.
+# 
+#   String Types (free-form text)
+#     Values are strings with minimal validation beyond type checking.
+#     Examples:
+#       - SERVICE_NAME (any non-empty string)
+#       - REDIS_KEY_PREFIX (any string, commonly with colon suffix)
+#     Empty strings are rejected unless explicitly allowed.

+# Changelog
+
+## Unreleased
+
+- **[#610] Remove orphaned `EventProcessor` / integrate dedup** — Deleted the
+  in-memory `EventProcessor` class and its test from `src/services/` (the file
+  was never imported or wired into the production code path). Deduplication is
+  fully handled at the DB boundary via `IndexerProcessedEvent` +
+  `idempotency.ts`. Added `DuplicateStats` to `idempotency.ts` so callers can
+  track cumulative inserted/duplicate counts for metrics and structured logging
+  without the unbounded memory growth of the old in-memory `Set`. Wired

+# Rate Limiting Policy
+
+This document outlines the rate limiting tiers applied to each endpoint in the Vatix Backend API. Rate limiting is enforced to protect against abuse, prevent resource exhaustion, and ensure fair access to the service.
+
+## Overview
+
+The API implements a tiered rate limiting system with the following global limits:
+
+| Tier                    | Requests per Minute | Use Case                                                        | Configurable Env Vars                                |
+| ----------------------- | ------------------- | --------------------------------------------------------------- | ---------------------------------------------------- |
+| **Global**              | 100                 | Default for all routes (except health/ready)                    | `RATE_LIMIT_MAX`, `RATE_LIMIT_WINDOW_MS`             |
+| **Heavy Read**          | 20                  | Expensive read operations requiring multiple DB queries         | `RATE_LIMIT_HEAVY_MAX`, `RATE_LIMIT_HEAVY_WINDOW_MS` |
+| **Write**               | 10                  | State mutations; strictest tier for non-admin                   | `RATE_LIMIT_WRITE_MAX`, `RATE_LIMIT_WRITE_WINDOW_MS` |
+| **Admin**               | 30                  | Privileged admin operations                                     | `RATE_LIMIT_ADMIN_MAX`, `RATE_LIMIT_ADMIN_WINDOW_MS` |
+| **Health/Ready Probes** | No limit            | Kubernetes readiness/liveness checks must never be rate-limited | N/A                                                  |
+
+## Endpoint Classification
+
+### Health & Readiness (No Rate Limit)
+
+These endpoints are critical for Kubernetes and monitoring infrastructure. They **must not be rate-limited** or require authentication.
+
+| Method | Path         | Tier | Reason                                                                      |
+| ------ | ------------ | ---- | --------------------------------------------------------------------------- |
+| `GET`  | `/v1/health` | None | Liveness probe; checks if HTTP server is alive. No dependency checks.       |
+| `GET`  | `/v1/ready`  | None | Readiness probe; checks database and indexer health before routing traffic. |
+
+### Read-Only Endpoints
+
+#### Low Risk (Global Limit - 100 req/min)
+
+Simple lookups with minimal computational cost.
+
+| Method | Path               | Tier   | Reason                                   |
+| ------ | ------------------ | ------ | ---------------------------------------- |
+| `GET`  | `/v1/markets/:id`  | Global | Single-row lookup by ID; O(1) operation. |
+| `GET`  | `/v1/openapi.json` | Global | Static file serving; minimal overhead.   |
+
+#### Medium Risk (Heavy Read Limit - 20 req/min)
+
+Expensive read operations involving joins, aggregations, or large result sets.
+
+| Method | Path                            | Tier       | Reason                                                                                |
+| ------ | ------------------------------- | ---------- | ------------------------------------------------------------------------------------- |
+| `GET`  | `/v1/markets`                   | Heavy Read | Table scan with optional filtering; can return up to 100 rows per request.            |
+| `GET`  | `/v1/markets/:id/orderbook`     | Heavy Read | Expensive aggregation: retrieves open orders, groups by price level, sorts bids/asks. |
+| `GET`  | `/v1/orders/user/:address`      | Heavy Read | Two DB queries (findMany + count); pagination support.                                |
+| `GET`  | `/v1/trades/user/:address`      | Heavy Read | Two DB queries with date range filtering; returns up to 100 rows per request.         |
+| `GET`  | `/v1/wallets/:wallet/positions` | Heavy Read | Joins positions with markets; optional per-market order-book query for PnL.           |
+
+### Write Endpoints (Write Limit - 10 req/min)
+
+State-mutating operations; strictest non-admin tier because side effects are costly and potentially conflicting.
+
+| Method | Path         | Tier  | Reason                                                                                             |
+| ------ | ------------ | ----- | -------------------------------------------------------------------------------------------------- |
+| `POST` | `/v1/orders` | Write | Creates order in database and runs matching engine logic; requires Stellar signature verification. |
+
+### Admin Endpoints (Admin Limit - 30 req/min)
+
+Privileged operations gated behind API key + admin role token. Requires `Authorization: Bearer <ADMIN_TOKEN>` header.
+
+| Method  | Path                           | Tier  | Reason                                                                              |
+| ------- | ------------------------------ | ----- | ----------------------------------------------------------------------------------- |
+| `GET`   | `/v1/admin/markets`            | Admin | Lists all markets (including cancelled); lower limit than public /markets endpoint. |
+| `PATCH` | `/v1/admin/markets/:id/status` | Admin | Mutates market status; requires elevated privileges.                                |
+
+---
+
+## Response Headers
+
+All responses include IETF-compliant rate limit headers:
+
+```
+RateLimit-Limit     — Maximum requests allowed in the current window
+RateLimit-Remaining — Requests remaining in the current window
+RateLimit-Reset     — Unix timestamp (seconds) when the window resets
+```
+
+When a client exceeds the rate limit, the API responds with:
+
+```
+HTTP 429 Too Many Requests
+Retry-After: <seconds-until-reset>
+
+{
+  "error": "Too Many Requests",
+  "code": "RATE_LIMITED",
+  "statusCode": 429,
+  "retryAfter": <seconds>
+}
+```
+
+The `Retry-After` header indicates how long the client should wait before retrying.
+
+---
+
+## How to Extend or Modify Rate Limits
+
+### Adding a New Endpoint
+
+When adding a new endpoint to the API:
+
+1. **Classify the endpoint** into one of the risk tiers above
+2. **Apply the limiter** in the route handler:
+   ```typescript
+   // Example: Heavy read endpoint
+   fastify.get("/new/endpoint", {
+     onRequest: [heavyReadLimiter],
+     // ...handler
+   });
+   ```
+3. **Add the route to the OpenAPI spec** in `src/api/openapi.ts`
+4. **Add unit tests** verifying the rate limit is enforced (see `src/api/middleware/rateLimiter.test.ts`)
+
+### Adjusting Limits
+
+Override default limits via environment variables:
+
+```bash
+# Global limits
+RATE_LIMIT_MAX=150              # Default: 100
+RATE_LIMIT_WINDOW_MS=60000      # Default: 60,000 (1 minute)
+
+# Heavy read limits
+RATE_LIMIT_HEAVY_MAX=30         # Default: 20
+RATE_LIMIT_HEAVY_WINDOW_MS=60000
+
+# Write limits
+RATE_LIMIT_WRITE_MAX=15         # Default: 10
+RATE_LIMIT_WRITE_WINDOW_MS=60000
+
+# Admin limits
+RATE_LIMIT_ADMIN_MAX=50         # Default: 30
+RATE_LIMIT_ADMIN_WINDOW_MS=60000
+```
+
+---
+
+## Testing
+
+Rate limiting is tested in `src/api/middleware/rateLimiter.test.ts`. Key test scenarios:
+
+- ✓ Request within limit is allowed (200 OK)
+- ✓ Request after exceeding limit returns 429
+- ✓ 429 response includes Retry-After header
+- ✓ Window resets after expiration
+- ✓ Separate tiers do not interfere with each other
+
+---
+
+## Future Enhancements
+
+- **User-based rate limiting**: Track limits per authenticated user or API key (currently per IP)
+- **Adaptive rate limiting**: Adjust limits based on server load
+- **Rate limit bypass for monitoring**: Allow health check requests to pass through without counting toward limits
+- **Distributed rate limiting**: For multi-instance deployments, use Redis or similar backing store

+# Resolution Migration - Implementation Summary
+
+## Assignment Completed ✓
+
+A migration for the `resolutions` table has been created to support finalized market resolutions for settlement and portfolio closeout.
+
+---
+
+## Files Created/Modified
+
+### 1. Migration File
+
+**Location**: `prisma/migrations/20260428000000_add_resolutions_table/migration.sql`
+
+**Contains**:
+
+- ✓ `ResolutionStatus` enum with values: `ACTIVE`, `CORRECTED`, `OVERRIDDEN`
+- ✓ `resolutions` table with:
+  - `id` (TEXT, PRIMARY KEY, UUID)
+  - `market_id` (TEXT, FOREIGN KEY → markets.id with CASCADE delete)
+  - `outcome` (BOOLEAN) - YES (true) or NO (false)
+  - `finalized_at` (TIMESTAMP) - When resolution was finalized
+  - `provenance` (TEXT) - Source attribution (e.g., CHAINLINK, PYTH, MANUAL)
+  - `status` (ResolutionStatus) - Tracks state transitions
+  - `correction_override_metadata` (JSONB) - Audit trail for corrections/overrides
+  - `created_at` (TIMESTAMP)
+  - `updated_at` (TIMESTAMP)
+- ✓ Enforces one ACTIVE resolution per market via partial unique index
+- ✓ 6 strategic indexes for query optimization
+
+### 2. Schema File
+
+**Location**: `prisma/schema.prisma`
+
+**Changes**:
+
+- ✓ Added `ResolutionStatus` enum (ACTIVE, CORRECTED, OVERRIDDEN)
+- ✓ Added `Resolution` model with:
+  - All required fields and relationships
+  - Unique constraint on `(marketId, ACTIVE status)`
+  - Proper field mappings to database column names
+  - Comprehensive indexes for performance
+  - Relationship to `Market` model with cascade delete
+- ✓ Updated `Market` model to include `resolutions` relationship
+
+### 3. Testing Guide
+
+**Location**: `RESOLUTION_MIGRATION_TESTING.md`
+
+**Includes**:
+
+- Migration overview and acceptance criteria verification
+- Step-by-step testing procedures
+- SQL verification queries

+- Rollback plan
+- Success criteria checklist
+
+---
+
+## Acceptance Criteria Met
+
+| Criterion                                       | Status | Details                                                                                               |
+| ----------------------------------------------- | ------ | ----------------------------------------------------------------------------------------------------- |
+| Resolution table keyed by market ID             | ✓      | Primary key is UUID `id`, foreign key relationship with `Markets`                                     |
+| Includes outcome field                          | ✓      | Boolean field: `true` = YES, `false` = NO                                                             |
+| Includes finalized_at field                     | ✓      | TIMESTAMP field for settlement cutoff                                                                 |
+| Includes provenance field                       | ✓      | TEXT field for source attribution                                                                     |
+| Enforces one active final resolution per market | ✓      | Partial unique index: `resolutions_market_id_active_idx` where status = 'ACTIVE'                      |
+| Correction/override metadata strategy           | ✓      | JSONB field `correction_override_metadata` with ResolutionStatus enum (ACTIVE, CORRECTED, OVERRIDDEN) |
+
+---
+
+## Key Features
+
+### 1. Data Integrity
+
+- Foreign key constraint with cascade delete for data consistency
+- Unique partial index prevents multiple active resolutions per market
+- NOT NULL constraints on critical fields
+
+### 2. Audit Trail
+
+- `correctionOverrideMetadata` JSONB field tracks:
+  - When correction occurred
+  - Previous outcome value
+  - Reason for correction/override
+  - Who made the change
+- Status transitions (ACTIVE → CORRECTED/OVERRIDDEN)
+
+### 3. Performance
+
+- Market lookups: `resolutions_market_id_idx`
+- Status filtering: `resolutions_status_idx`
+- Temporal queries: `resolutions_finalized_at_idx`
+- Compound queries: `resolutions_market_id_status_idx`
+- Pagination: `resolutions_created_at_idx` (DESC)
+
+### 4. Settlement Support
+
+- `finalizedAt` timestamp for settlement window enforcement
+- `outcome` boolean for payout calculations
+- `status` field distinguishes between active and historical resolutions
+- Cascade delete ensures referential integrity when markets are archived
+

+
+## How to Apply the Migration
+
+### Development
+
+```bash
+cd /workspaces/vatix-backend
+pnpm prisma:migrate dev --name "verify resolutions migration"
+```
+
+### Production
+
+```bash
+pnpm prisma:deploy
+```
+
+### Validation
+
+```bash
+pnpm prisma:generate  # Regenerate Prisma client
+pnpm test             # Run test suite
+```
+
+---
+
+## How to Verify Completion
+
+### 1. Check Migration Applied
+
+```sql
+SELECT * FROM "_prisma_migrations"
+WHERE migration = '20260428000000_add_resolutions_table';
+```
+
+### 2. Verify Table Structure
+
+```sql
+\d resolutions
+```
+
+### 3. Test One-Active-Per-Market Constraint
+
+```sql
+-- Insert first resolution (should succeed)
+INSERT INTO resolutions (id, market_id, outcome, finalized_at, provenance, status)
+VALUES ('res-1', 'market-1', true, NOW(), 'TEST', 'ACTIVE');
+
+-- Try inserting second ACTIVE resolution (should fail)
+INSERT INTO resolutions (id, market_id, outcome, finalized_at, provenance, status)
+VALUES ('res-2', 'market-1', false, NOW(), 'TEST', 'ACTIVE');
+-- Expected: Error: duplicate key violates unique constraint
+
+-- Insert with different status (should succeed)
+INSERT INTO resolutions (id, market_id, outcome, finalized_at, provenance, status)
+VALUES ('res-2', 'market-1', false, NOW(), 'TEST', 'CORRECTED');
+```
+
+### 4. Test Prisma ORM Integration
+
+```typescript
+import { prisma } from "@/services/prisma";
+
+// Query should work
+const activeResolution = await prisma.resolution.findFirst({
+  where: { status: "ACTIVE" },
+});
+
+console.log("✓ Prisma client can access Resolution model");
+```
+
+---
+
+## Architecture Notes
+
+### Resolution Lifecycle
+
+1. **ACTIVE**: Current final resolution for the market
+2. **CORRECTED**: Previous ACTIVE resolution that was corrected (new one becomes ACTIVE)
+3. **OVERRIDDEN**: Previous ACTIVE resolution that was overridden (new one becomes ACTIVE)
+
+### Correction Strategy
+
+When a resolution needs to be corrected:
+
+1. Update existing ACTIVE resolution to CORRECTED/OVERRIDDEN status
+2. Store previous state in `correctionOverrideMetadata`
+3. Create new ACTIVE resolution with updated outcome
+4. Partial unique index prevents simultaneous active resolutions
+
+### Settlement Workflow
+
+1. Market reaches `endTime`
+2. Resolution consensus established (via resolution candidates)
+3. Final resolution created with `outcome` and `finalizedAt`
+4. Settlement engine uses `finalizedAt` for cutoff
+5. Portfolio closeout completed
+6. Historical resolutions preserved for audit

+# Resolutions Table Migration - Testing & Verification Guide
+
+## Overview
+
+This migration adds the `resolutions` table to support finalized market resolutions. The table includes:
+
+- **Market ID keying**: Each resolution is linked to a market
+- **One active resolution per market**: Enforced via partial unique index on `market_id` WHERE `status = 'ACTIVE'`
+- **Outcome tracking**: Boolean field for YES/NO resolution
+- **Finalized timestamp**: When the resolution became final
+- **Provenance**: Source attribution (oracle, manual, override, etc.)
+- **Correction/Override metadata**: JSONB field for tracking historical corrections and overrides
+
+## Migration Details
+
+**Migration Name**: `20260428000000_add_resolutions_table`  
+**Location**: `prisma/migrations/20260428000000_add_resolutions_table/migration.sql`
+
+### Schema Changes
+
+#### New Enum: ResolutionStatus
+
+```
+ACTIVE       - Current active resolution
+CORRECTED    - Resolution that has been corrected (new one is ACTIVE)
+OVERRIDDEN   - Resolution that was overridden (new one is ACTIVE)
+```
+
+#### New Table: resolutions
+
+```sql
+CREATE TABLE "resolutions" (
+    "id" TEXT PRIMARY KEY,
+    "market_id" TEXT NOT NULL,           -- References markets.id (CASCADE delete)
+    "outcome" BOOLEAN NOT NULL,          -- YES (true) or NO (false)
+    "finalized_at" TIMESTAMP NOT NULL,   -- When resolution finalized
+    "provenance" TEXT NOT NULL,          -- Source (CHAINLINK, PYTH, MANUAL, etc.)
+    "status" ResolutionStatus DEFAULT 'ACTIVE',
+    "correction_override_metadata" JSONB, -- Correction/override history
+    "created_at" TIMESTAMP,
+    "updated_at" TIMESTAMP
+);
+```
+
+#### Indexes Created
+
+- `resolutions_market_id_active_idx` (unique, partial) - Enforces one ACTIVE resolution per market
+- `resolutions_market_id_idx` - Fast lookups by market
+- `resolutions_status_idx` - Filter by resolution status
+- `resolutions_finalized_at_idx` - Temporal queries
+- `resolutions_market_id_status_idx` - Compound filtering
+- `resolutions_created_at_idx` - Pagination/ordering
+
+## Testing Steps
+
+### 1. Apply Migration
+
+```bash
+# Development environment
+pnpm prisma:migrate dev --name "verify resolutions migration"
+
+# Production environment
+pnpm prisma:deploy
+```
+
+### 2. Verify Schema in Database
+
+```bash
+# Connect to database and check table structure
+pnpm prisma:studio
+
+# Or use SQL directly
+psql $DATABASE_URL -c "\d resolutions"
+```
+
+Expected output should show all columns with correct types.
+
+### 3. Test Acceptance Criteria
+
+#### A. Resolution Keyed by Market ID
+
+```sql
+-- Insert a market first
+INSERT INTO markets (id, question, end_time, resolution_time, oracle_address, status)
+VALUES (
+  'test-market-1',
+  'Will Bitcoin reach $100k?',
+  NOW() + INTERVAL '30 days',
+  NOW() + INTERVAL '31 days',
+  'GBXYZ...',
+  'ACTIVE'
+);
+
+-- Insert a resolution
+INSERT INTO resolutions (id, market_id, outcome, finalized_at, provenance, status)
+VALUES (
+  'res-1',
+  'test-market-1',
+  true,
+  NOW(),
+  'CHAINLINK',
+  'ACTIVE'
+);
+
+-- Verify retrieval by market_id
+SELECT * FROM resolutions WHERE market_id = 'test-market-1';
+```
+
+#### B. Outcome, Finalized At, and Provenance Fields
+
+```sql
+-- Verify all fields are populated correctly
+SELECT id, market_id, outcome, finalized_at, provenance, status
+FROM resolutions
+WHERE market_id = 'test-market-1';
+
+-- Expected: outcome=true, finalized_at=<timestamp>, provenance='CHAINLINK', status='ACTIVE'
+```
+
+#### C. One Active Resolution Per Market (Constraint)
+
+```sql
+-- This should FAIL (unique constraint violation)
+INSERT INTO resolutions (id, market_id, outcome, finalized_at, provenance, status)
+VALUES (
+  'res-2',
+  'test-market-1',
+  false,
+  NOW(),
+  'MANUAL',
+  'ACTIVE'
+);
+
+-- Expected Error: duplicate key value violates unique constraint "resolutions_market_id_active_idx"
+
+-- This should SUCCEED (different status)
+INSERT INTO resolutions (id, market_id, outcome, finalized_at, provenance, status)
+VALUES (
+  'res-2',
+  'test-market-1',
+  false,
+  NOW(),
+  'MANUAL',
+  'CORRECTED'
+);
+
+-- Verify only one ACTIVE per market
+SELECT status, COUNT(*) FROM resolutions GROUP BY market_id, status HAVING COUNT(*) > 1;
+-- Expected: (empty result)
+```
+
+#### D. Correction/Override Metadata Strategy
+
+```sql
+-- Test with correction metadata
+UPDATE resolutions
+SET status = 'CORRECTED',
+    correction_override_metadata = jsonb_build_object(
+      'corrected_at', NOW()::text,
+      'previous_outcome', false,
+      'reason', 'Data validation error in oracle source',
+      'corrected_by', 'oracle-ops'
+    )
+WHERE id = 'res-1';
+
+-- Verify metadata was stored
+SELECT id, status, correction_override_metadata
+FROM resolutions
+WHERE id = 'res-1';
+
+-- Example metadata structure
+-- {
+--   "corrected_at": "2026-04-28T14:30:00Z",
+--   "previous_outcome": false,
+--   "reason": "Data validation error in oracle source",
+--   "corrected_by": "oracle-ops"
+-- }
+```
+
+### 4. Integration with Prisma ORM
+
+#### Generate Prisma Client
+
+```bash
+pnpm prisma:generate
+```
+
+#### Usage Example (TypeScript)
+
+```typescript
+import { prisma } from "@/services/prisma";
+
+// Create a resolution
+const resolution = await prisma.resolution.create({
+  data: {
+    marketId: "market-123",
+    outcome: true,
+    finalizedAt: new Date(),
+    provenance: "CHAINLINK",
+    status: "ACTIVE",
+  },
+});
+
+// Query active resolutions
+const activeResolutions = await prisma.resolution.findMany({
+  where: { status: "ACTIVE" },
+  include: { market: true },
+});
+
+// Get resolution for specific market
+const marketResolution = await prisma.resolution.findUniqueOrThrow({
+  where: {
+    marketId_status: {
+      marketId: "market-123",
+      status: "ACTIVE",
+    },
+  },
+});
+
+// Update resolution to corrected with metadata
+const corrected = await prisma.resolution.update({
+  where: { id: "res-123" },
+  data: {
+    status: "CORRECTED",
+    correctionOverrideMetadata: {
+      corrected_at: new Date().toISOString(),
+      previous_outcome: false,
+      reason: "Oracle data validation issue",
+    },
+  },
+});
+```
+
+### 5. Run Full Test Suite
+
+```bash
+# Run all tests including integration tests
+pnpm test
+
+# Run specific test file
+pnpm test tests/integration/
+
+# Check test coverage
+pnpm test:coverage
+```
+
+## Verification Queries
+
+### Check Migration Applied
+
+```sql
+SELECT * FROM "_prisma_migrations"
+WHERE migration = '20260428000000_add_resolutions_table'
+ORDER BY finished_at DESC LIMIT 1;
+```
+
+### View Table Structure
+
+```sql
+\d resolutions
+```
+
+### Verify Indexes
+
+```sql
+SELECT indexname, indexdef
+FROM pg_indexes
+WHERE tablename = 'resolutions';
+```
+
+### Test Constraint
+
+```sql
+-- Count ACTIVE resolutions per market (should be 0 or 1 for each)
+SELECT market_id, COUNT(*) as active_count
+FROM resolutions
+WHERE status = 'ACTIVE'
+GROUP BY market_id
+HAVING COUNT(*) > 1;
+-- Expected: (empty result - no violations)
+```
+
+## Rollback Plan
+
+If you need to rollback this migration:
+
+```bash
+# Development environment
+pnpm prisma:migrate resolve --rolled-back 20260428000000_add_resolutions_table
+
+# Production environment
+pnpm prisma:migrate resolve --rolled-back 20260428000000_add_resolutions_table --skip-generate
+```
+
+Manual SQL rollback (if needed):
+
+```sql
+DROP TABLE IF EXISTS resolutions CASCADE;
+DROP TYPE IF EXISTS "ResolutionStatus";
+```
+
+## Notes
+
+1. **Cascade Deletes**: When a market is deleted, all associated resolutions are automatically deleted
+2. **Corrected/Overridden Tracking**: Use `correctionOverrideMetadata` JSONB field to maintain audit trail
+3. **Partial Unique Index**: Only `ACTIVE` resolutions are enforced as unique per market, allowing historical tracking
+4. **Sentinel Provenance Values**: Use standardized provenance values (e.g., 'CHAINLINK', 'PYTH', 'MANUAL', 'OVERRIDE', 'API3', 'UMA')
+
+## Success Criteria
+
+✅ Migration applies without errors  
+✅ Table structure matches schema  
+✅ One ACTIVE resolution per market constraint enforced  
+✅ Correction metadata is stored and retrievable  
+✅ Foreign key cascades work correctly  
+✅ All indexes created successfully  
+✅ Prisma ORM client generates successfully

+# Workers
+
+Background execution module for queue consumers and scheduled jobs.
+
+Workers handle tasks that must run outside the HTTP request lifecycle: settlement sweeps, expiry processing, and any other async work enqueued by the API or Oracle.
+
+## Scope
+
+| Concern             | Description                                                               |
+| ------------------- | ------------------------------------------------------------------------- |
+| **Queue consumers** | Process jobs pushed to Redis by the API or Oracle (e.g. trade settlement) |
+| **Scheduled jobs**  | Cron-style tasks such as market expiry sweeps and position reconciliation |
+
+## Status
+
+Module scaffolded. No queues or jobs are implemented yet.
+See [docs/architecture.md](../../docs/architecture.md) for how Workers fit into the overall system.
+
+## Structure (planned)
+
+```
+apps/workers/
+├── src/
+│   ├── consumers/   # One file per queue consumer
+│   ├── schedulers/  # Cron / interval jobs
+│   └── index.ts     # Entry point
+└── README.md
+```
+
+## Running
+
+```bash
+# Not yet available — implementation pending
+```
+
+## Adding a Worker
+
+1. Create a consumer in `src/consumers/<name>.ts` or a scheduler in `src/schedulers/<name>.ts`
+2. Register it in `src/index.ts`
+3. Document the queue name and payload shape in this README

+# ADR 001 — Queue Technology: BullMQ vs Redis Streams vs SQS
+
+**Status:** Accepted  
+**Date:** 2026-06-20  
+**Issue:** [#452](https://github.com/Debbys-design/vatix-backend/issues/452)  
+**Closes open decision in:** `docs/architecture.md`
+
+---
+
+## Context
+
+The architecture doc listed this as an open decision:
+
+> **Queue technology**: Redis (BullMQ) is assumed for Workers but not yet implemented.
+> Evaluate whether a managed queue (SQS, etc.) is preferable before first production deploy.
+
+The current codebase uses ad-hoc Redis Streams patterns (`xadd`/`xreadgroup`/`xack`) written directly
+in `apps/workers/src/settlement/consumer.ts` and `apps/workers/src/oracle/redis-submission-queue.ts`.
+Each consumer re-implements retry counting, backoff, dead-letter logging, and visibility timeouts
+in an inconsistent way. This ADR evaluates three options and records the decision.
+
+---
+
+## Options Considered
+
+### Option A — BullMQ
+
+BullMQ is a Node.js queue library built on Redis. It provides:
+
+- **Unified job lifecycle**: pending → active → completed / failed, with automatic retry and backoff.
+- **Dead-letter queue (DLQ)**: failed jobs move to a `failed` set; accessible via dashboard or API.
+- **Concurrency control** and **rate limiting** at the queue level.
+- **Repeatable/scheduled jobs** via `QueueScheduler`.
+- **TypeScript-first** API with full type inference on job data.
+- **Single Redis connection** — no separate infrastructure.
+- **BullMQ Board** optional UI for observability.
+
+Tradeoffs:
+- Adds `bullmq` dependency (well-maintained, MIT licence).
+- Jobs are stored as Redis hashes; slightly higher memory per job than raw streams.
+- Requires Redis ≥ 6.2 (already satisfied by the `redis:7-alpine` service in `docker-compose.yml`).
+
+### Option B — Raw Redis Streams (status quo)
+
+The current approach manually wraps `XADD`/`XREADGROUP`/`XACK`/`XCLAIM`.
+
+- No additional dependency.
+- Full control over stream semantics.
+- Must re-implement: retry backoff, DLQ, concurrency, job state tracking, observability — all by hand.
+- Already showing divergence between settlement and oracle consumers (different retry logic, different
+  visibility timeout approaches).
+
+### Option C — Amazon SQS
+
+Managed cloud queue with at-least-once delivery, DLQ support, and long-polling.
+
+- Eliminates operational Redis queue concerns.
+- Introduces AWS SDK dependency and requires an AWS account / IAM setup.
+- Local development requires LocalStack or mocking.
+- Adds network round-trip latency vs in-process Redis.
+- Significant infrastructure change out of scope for the current mono-Redis deployment.
+
+---
+
+## Decision
+
+**BullMQ** is selected.
+
+The project already runs Redis and the existing ad-hoc stream consumers are re-implementing
+exactly what BullMQ provides — badly and inconsistently. BullMQ gives a single, well-tested
+abstraction for retry/backoff/DLQ that all queues (settlement, oracle submission) can share.
+SQS is ruled out because it introduces cloud infrastructure coupling before the system has
+reached production; it can be revisited if operational requirements change.
+
+---
+
+## Consequences
+
+1. Add `bullmq` to root `package.json` dependencies.
+2. Replace `apps/workers/src/settlement/consumer.ts` raw-stream bootstrap with a BullMQ `Worker`.
+3. Replace `apps/workers/src/oracle/redis-submission-queue.ts` with a BullMQ `Queue` producer and
+   `Worker` consumer pair.
+4. Unified retry config: `attempts`, `backoff` strategy, and `removeOnFail` (DLQ retention) defined
+   once per queue in a shared config object.
+5. `queue-consumer.ts` generic `processJob` function is preserved — BullMQ workers call it so
+   existing unit tests continue to pass without modification.
+6. The `SETTLEMENT_QUEUE_NAME` and `SUBMISSION_QUEUE_NAME` env vars continue to control queue names.
+
+---
+
+## Unified Retry / Backoff / DLQ Config
+
+```ts
+// Shared defaults — override per queue as needed
+export const DEFAULT_JOB_OPTIONS = {
+  attempts: 3,
+  backoff: { type: "exponential", delay: 1_000 },
+  removeOnComplete: { count: 100 },   // keep last 100 completed jobs
+  removeOnFail: false,                 // keep ALL failed jobs as DLQ
+} as const;
+```
+
+Failed jobs (DLQ) are accessible via:
+```ts
+const failed = await queue.getFailed();
+```

+# API Versioning
+
+## Overview
+
+All public API routes are versioned under the `/v1` prefix.
+
+```
+GET /v1/health
+```
+
+Non-versioned paths (e.g. `GET /health`) are supported as compatibility redirects to the canonical versioned path.
+The server responds with `308 Permanent Redirect` and includes `Location`, `Deprecation`, `Sunset`, and `Link` headers until `2027-01-01T00:00:00Z`.
+Deprecated path usage is logged with `{ event: "api.deprecated_path", path, clientIp }`.
+After the sunset timestamp, unversioned paths return `404`.
+
+## Public Route Table
+
+| Method | Canonical path                  | Legacy alias                | Notes                           |
+| ------ | ------------------------------- | --------------------------- | ------------------------------- |
+| GET    | `/v1/health`                    | `/health`                   | Liveness and health summary     |
+| GET    | `/v1/ready`                     | `/ready`, `/readiness`      | Readiness checks                |
+| GET    | `/v1/markets`                   | `/markets`                  | Market listing                  |
+| GET    | `/v1/markets/:id`               | `/markets/:id`              | Market details                  |
+| GET    | `/v1/markets/:id/orderbook`     | `/markets/:id/orderbook`    | Market orderbook                |
+| POST   | `/v1/orders`                    | `/orders`                   | Create order                    |
+| GET    | `/v1/orders/user/:address`      | `/orders/user/:address`     | Wallet order history            |
+| GET    | `/v1/trades/user/:address`      | `/trades/user/:address`     | Wallet trade history            |
+| GET    | `/v1/wallets/:wallet/positions` | `/positions/user/:address`  | Canonical wallet positions path |
+| GET    | `/v1/admin/markets`             | `/admin/markets`            | Requires API key and admin auth |
+| PATCH  | `/v1/admin/markets/:id/status`  | `/admin/markets/:id/status` | Requires API key and admin auth |
+| GET    | `/v1/openapi.json`              | none                        | OpenAPI specification           |
+
+## Adding New Routes
+
+Register all new routes inside the `v1` plugin in `src/index.ts` so they
+automatically inherit the `/v1` prefix:
+
+```ts
+server.register(
+  async (v1) => {
+    v1.get("/your-route", handler);
+  },
+  { prefix: "/v1" }
+);
+```
+
+## Backwards Compatibility Policy
+
+- Routes within a version (e.g. `/v1`) are **stable**. Breaking changes
+  (removed fields, changed semantics, altered response shapes) are not
+  permitted without introducing a new version prefix (e.g. `/v2`).
+- Additive changes (new optional fields, new endpoints) are allowed within
+  the same version.
+- When a new version is introduced, the previous version will be supported
+  for a documented deprecation window before removal.
+- Deprecation notices will be communicated via response headers
+  (`Deprecation`, `Sunset`) and updated in this document.
+- Root-level compatibility aliases are temporary only. New clients must use
+  `/v1/*` paths and must not introduce new unversioned API URLs.
+
+## Current Versions
+
+| Version | Status | Base path | Notes                  |
+| ------- | ------ | --------- | ---------------------- |
+| v1      | Active | `/v1`     | Initial public version |

+
+## System Overview
+
+Vatix Backend is a monorepo of services that together power the Vatix prediction market protocol on Stellar.

+| ------------- | --------------- | --------------------------------------------------------------------------------------------------------------- |
+| **API**       | `src/`          | HTTP server (Fastify). Handles order placement, market queries, position reads. Owns the CLOB matching engine.  |
+| **Indexer**   | `apps/indexer/` | Polls Stellar network for on-chain events, parses them, and writes canonical records to PostgreSQL.             |
+| **Oracle**    | `apps/oracle/`  | Fetches external price/resolution data, signs reports, and submits them on-chain via the Stellar SDK.           |
+| **Workers**   | `apps/workers/` | Queue consumers and scheduled jobs (e.g. settlement, expiry sweeps). Decoupled from the HTTP request lifecycle. |
+| **Shared DB** | `packages/db/`  | Shared Prisma client and migration utilities used by all services.                                              |
+
+## Major Data Flows
+
+All public HTTP routes are mounted under `/v1`. The canonical positions read is
+`GET /v1/wallets/:wallet/positions`; the older
+`GET /positions/user/:address` root path is a temporary deprecation redirect.
+
+### Order placement
+
+1. Client `POST /v1/orders` → API validates and writes order to PostgreSQL
+2. CLOB matching engine runs synchronously; fills are written in the same transaction
+3. Matched fills are enqueued to Redis for downstream settlement by Workers
+
+### Submission queue
+
+The API and Oracle submit asynchronous work into Redis-backed queues that are processed by the Workers service.
+This submission queue decouples real-time HTTP request handling from downstream settlement and finalization.
+
+Workers consume queue entries and perform background tasks such as trade settlement, expiry sweeps, and resolution candidate processing.
+
+### Market resolution
+
+1. Oracle fetches external outcome data and signs a resolution report
+2. Oracle submits the report on-chain (Stellar)
+3. Indexer detects the on-chain event and writes a `ResolutionCandidate` to PostgreSQL
+4. Workers pick up the candidate, apply the challenge window, and settle positions
+
+### Indexer cursor
+
+- The Indexer stores a `ledger_cursor` in PostgreSQL (`IndexerCursor` table) to resume from the last processed ledger after restarts.
+
+## Open Decisions
+
+- [x] **Queue technology**: Resolved — BullMQ selected. See [docs/adr/001-queue-technology.md](adr/001-queue-technology.md). Settlement and oracle submission queues migrated to BullMQ Workers with unified retry/backoff/DLQ config.
+- [ ] **Oracle multi-provider strategy**: `fallback-adapter.ts` exists but the failover policy (timeout, retry count) is not finalised.
+- [ ] **Monorepo build tooling**: Services currently share `tsconfig.json` at the root. Evaluate per-package tsconfigs as the repo grows.
+- [ ] **Authentication**: Admin routes use a static key guard (`adminGuard.ts`). A proper auth layer is needed before public launch.
+- [x] **Workers deployment**: resolved — the root [`Dockerfile`](../Dockerfile) defines `finalization-worker` and `oracle-worker` build targets, and [`docker-compose.yml`](../docker-compose.yml) runs them under the `workers` profile. No standalone process manager is used; each container runs a single process and relies on Docker/Kubernetes restart policies. See [docs/docker-compose.md](docker-compose.md).
+
+## Assumptions
+
+- All services share a single PostgreSQL instance (separate schemas are not used)
+- Redis is used exclusively for caching and job queues (no persistence guarantees relied upon)
+- Stellar Horizon is the only chain data source; no EVM chains are in scope

+# Request Body Size Limit
+
+All API endpoints enforce a maximum request payload size to prevent large
+payloads from degrading performance or enabling abuse.
+
+## Default limit
+
+**64 KB** (65 536 bytes) — sufficient for all current JSON payloads.
+
+File upload endpoints are out of scope at MVP; exceptions can be handled per
+route in a future iteration.
+
+## Configuration
+
+Override the global limit via the `BODY_LIMIT_BYTES` environment variable:
+
+```env
+BODY_LIMIT_BYTES=65536
+```
+
+The value is read once at server startup. Changes require a restart.
+
+## Response
+
+Requests whose body exceeds the configured limit are rejected before any route
+handler runs:
+
+- **Status**: `413 Request Entity Too Large`
+- **Body**:
+
+```json
+{
+  "error": "Request body is too large",
+  "statusCode": 413
+}
+```
+
+## Notes
+
+- The limit applies globally to every route.
+- The `bodyLimit` option is passed directly to Fastify, which enforces it at
+  the HTTP layer before JSON parsing.
+- Per-route overrides are possible via Fastify's route-level `bodyLimit` option
+  if specific endpoints ever need a different ceiling.

+# CORS Configuration
+
+Cross-Origin Resource Sharing (CORS) is configured in the Vatix Backend to control which origins can make requests to the API. The configuration is driven by environment variables and supports both restrictive defaults and flexible local development setups.
+
+## Overview
+
+The API uses the `@fastify/cors` plugin with custom origin validation. All CORS-related policies are centralized in the [`src/api/middleware/cors.ts`](../src/api/middleware/cors.ts) module.
+
+## Allowed Origins
+
+Allowed origins are controlled by the `CORS_ALLOWED_ORIGINS` environment variable (comma-separated list). If not set, the API falls back to environment-specific defaults:
+
+| Environment          | Default Origins                                   |
+| -------------------- | ------------------------------------------------- |
+| **Production**       | None (empty list — must be explicitly configured) |
+| **Development/Test** | `http://localhost:3000`, `http://localhost:5173`  |
+
+### Configuration Examples
+
+#### Production Setup
+
+For production, explicitly allow your frontend origins:
+
+```bash
+CORS_ALLOWED_ORIGINS=https://app.vatix.io,https://staging.vatix.io
+```
+
+#### Local Development
+
+For development, the default configuration automatically allows localhost on common ports:
+
+```bash
+# No CORS_ALLOWED_ORIGINS needed — defaults to:
+# - http://localhost:3000
+# - http://localhost:5173
+```
+
+To add additional local origins, set the variable explicitly:
+
+```bash
+CORS_ALLOWED_ORIGINS=http://localhost:3000,http://localhost:5173,http://localhost:8080
+```
+
+## Permitted Methods and Headers
+
+The following HTTP methods are allowed on all CORS requests:
+
+| Method  |
+| ------- |
+| GET     |
+| POST    |
+| PUT     |
+| PATCH   |
+| DELETE  |
+| OPTIONS |
+
+The following request headers are allowed:
+
+| Header          |
+| --------------- |
+| `Content-Type`  |
+| `Authorization` |
+| `X-Request-Id`  |
+
+The following response headers are exposed to the client:
+
+| Header         |
+| -------------- |
+| `X-Request-Id` |
+
+## Credentials Support
+
+Credentials (cookies, HTTP authentication headers) are supported:
+
+```
+credentials: true
+```
+
+This means cross-origin requests with `credentials: 'include'` or `withCredentials: true` are allowed, and response headers like `Set-Cookie` are sent to the client.
+
+## Same-Origin Requests
+
+Requests without an `Origin` header (same-origin requests) are always allowed, regardless of origin configuration.
+
+## Preflight Requests
+
+The API automatically handles CORS preflight (OPTIONS) requests:
+
+- Preflight requests are responded to immediately with appropriate CORS headers
+- Strict preflight validation is disabled (`strictPreflight: false`), allowing flexibility in non-standard setups
+
+## Implementation Details
+
+The CORS configuration is applied as a Fastify plugin registered in [`src/index.ts`](../src/index.ts) before any routes. This ensures all requests — including 404 responses — respect CORS policies.
+
+### Code Reference
+
+```typescript
+// Location: src/api/middleware/cors.ts
+export const corsPlugin = fp(async (fastify: FastifyInstance) => {
+  const allowedOrigins = getAllowedOrigins();
+
+  await fastify.register(cors, {
+    origin: (origin, callback) => {
+      // Same-origin requests are always allowed
+      if (!origin) {
+        callback(null, true);
+        return;
+      }
+      // Check against allowed list
+      if (allowedOrigins.includes(origin)) {
+        callback(null, true);
+      } else {
+        callback(new Error(`Origin '${origin}' not allowed`), false);
+      }
+    },
+    methods: ["GET", "POST", "PUT", "PATCH", "DELETE", "OPTIONS"],
+    allowedHeaders: ["Content-Type", "Authorization", "X-Request-Id"],
+    exposedHeaders: ["X-Request-Id"],
+    credentials: true,
+    preflight: true,
+    strictPreflight: false,
+  });
+});
+```
+
+## Troubleshooting
+
+### CORS Error in Browser
+
+If you see a CORS error in the browser, verify:
+
+1. The frontend origin is in the `CORS_ALLOWED_ORIGINS` list (or using a default if applicable)
+2. The request method is in the allowed methods list (GET, POST, PUT, PATCH, DELETE, OPTIONS)
+3. The request headers are in the allowed headers list or are safe headers (Content-Type, etc.)
+4. The API is running and reachable at the configured endpoint
+
+### Localhost Not Working
+
+If localhost is not working in development:
+
+1. Check `NODE_ENV` — should be `development` or `test` for localhost defaults
+2. If `CORS_ALLOWED_ORIGINS` is set, it overrides defaults — ensure localhost origins are included
+3. Verify the frontend is using the correct protocol and port (e.g., `http://localhost:3000`, not `https://localhost:3000`)

+# Dead Letter Log
+
+This document describes the dead letter logging mechanism used by the workers queue consumers.
+
+## Overview
+
+When a job fails permanently (after all retry attempts are exhausted), the queue consumer records the failed message via the dead letter log rather than silently discarding it. This ensures every terminal failure is captured for debugging and operational visibility.
+
+## How It Works
+
+The dead letter log lives in `apps/workers/src/consumers/dead-letter.ts` and exposes two items:
+
+### `DeadLetterMessage` (interface)
+
+| Field     | Type      | Description                                     |
+| --------- | --------- | ----------------------------------------------- |
+| `id`      | `string`  | Unique identifier of the failed message         |
+| `queue`   | `string`  | Name of the queue the message originated from   |
+| `payload` | `unknown` | Original job payload (opaque to the logger)     |
+| `reason`  | `string`  | Human-readable reason the job was dead-lettered |
+
+### `logDeadLetter(logger, message)` (function)
+
+Accepts a structured logger instance and a `DeadLetterMessage`, then writes an `error`-level log entry with structured fields:
+
+```typescript
+import { logDeadLetter, type DeadLetterMessage } from "./dead-letter.js";
+
+const message: DeadLetterMessage = {
+  id: "msg-123",
+  queue: "settlement",
+  payload: { tradeId: "t-456" },
+  reason: "Max retries exceeded",
+};
+
+logDeadLetter(logger, message);
+// => logger.error("Job dead-lettered", { messageId, queue, reason, payloadType, timestamp })
+```
+
+**Log fields emitted:**
+
+| Field         | Source                     | Description                              |
+| ------------- | -------------------------- | ---------------------------------------- |
+| `messageId`   | `message.id`               | Correlates with upstream job ID          |
+| `queue`       | `message.queue`            | Which queue the message came from        |
+| `reason`      | `message.reason`           | Why the message was dead-lettered        |
+| `payloadType` | `typeof message.payload`   | JS type of the payload (e.g. `"object"`) |
+| `timestamp`   | `new Date().toISOString()` | When the dead letter was recorded        |
+
+> **Note:** The `payload` value is intentionally **not** logged to avoid leaking sensitive data. `payloadType` gives operators enough context to distinguish missing payloads from structured ones. If you need payload details, inspect the dead letter store or enable `debug`-level logging upstream.
+
+## When Messages Are Dead-Lettered
+
+A message is sent to the dead letter log when:
+
+1. **Max retries exceeded** — The queue consumer has attempted the job `maxAttempts` times and all attempts failed.
+2. **Poison messages** — A message causes a non-retryable error (e.g. schema validation failure).
+
+## Testing
+
+A Vitest test file is colocated at `apps/workers/src/consumers/dead-letter.test.ts`. It verifies:
+
+- `logDeadLetter` calls `logger.error` exactly once
+- Structured fields (`messageId`, `queue`, `reason`, `payloadType`, `timestamp`) are present in the log output
+
+Run tests:
+
+```bash
+pnpm test:run
+```

+# Deployment Runbook
+
+This runbook covers standard deployment procedures for the vatix-backend service.
+
+## Services
+
+vatix-backend deploys as four independent containers built from the same root
+[`Dockerfile`](../Dockerfile), one `--target` per process, plus the shared
+PostgreSQL and Redis data layer. See [docs/docker-compose.md](docker-compose.md)
+for the full service/profile reference and [docs/architecture.md](architecture.md)
+for how the processes relate to each other.
+
+| Process             | Image target          | Depends on      |
+| ------------------- | --------------------- | --------------- |
+| API                 | `api`                 | Postgres, Redis |
+| Indexer             | `indexer`             | Postgres        |
+| Finalization worker | `finalization-worker` | Postgres        |
+| Oracle worker       | `oracle-worker`       | Postgres, Redis |
+
+## Standard Deployment
+
+1. **Build images** for the commit being deployed (one build per process,
+   sharing Docker layer cache):
+
+   ```bash
+   docker compose build api indexer finalization-worker oracle-worker
+   ```
+
+2. **Run database migrations** before rolling out new app containers:
+
+   ```bash
+   docker compose --profile migrate up --build migrate
+   ```
+
+   The `migrate` service runs `prisma migrate deploy` and exits — it is not a
+   long-running process. Confirm it exits with status `0` before proceeding.
+
+3. **Roll out the app containers:**
+
+   ```bash
+   docker compose --profile app up -d
+   ```
+
+4. **Verify health** of each service:
+
+   ```bash
+   curl -f http://localhost:3000/v1/health
+   curl -f http://localhost:3000/v1/ready
+   docker compose ps
+   ```
+
+   `/v1/health` confirms the API process and its DB connection are up.
+   `/v1/ready` additionally checks indexer freshness — see
+   [src/api/routes/ready.ts](../src/api/routes/ready.ts).
+
+5. **Tail logs** during rollout to catch startup failures early:
+
+   ```bash
+   docker compose logs -f api indexer finalization-worker oracle-worker
+   ```
+
+## Rolling Back
+
+1. Re-deploy the previous image tag/commit for the affected service(s):
+
+   ```bash
+   docker compose --profile app up -d --build api   # example: API only
+   ```
+
+2. If the rollback is due to a bad migration, follow the
+   [Migration Rollback Procedure](./migration-rollback.md) first — schema
+   rollbacks must happen before old application code is rolled back in, since
+   old code is not guaranteed to be forward-compatible with a newer schema.
+
+## Stopping a Deployment
+
+```bash
+docker compose --profile app down
+```
+
+This stops the app containers; `postgres` and `redis` keep running unless you
+also drop the default profile (`docker compose down`).
+
+## Graceful Shutdown
+
+All processes handle `SIGTERM`/`SIGINT` and the Dockerfile sets
+`STOPSIGNAL SIGTERM`, so `docker stop` / `docker compose stop` triggers a clean
+shutdown (in-flight work completes, DB/Redis connections close) rather than a
+hard kill. See [Graceful Shutdown](graceful-shutdown.md) for the implementation
+pattern and per-process timeout configuration
+(`WORKERS_SHUTDOWN_TIMEOUT_MS` in `.env.example`).
+
+## If Something Goes Wrong
+
+See the [Incident Response Runbook](./runbooks/incident-runbook.md) for
+service-specific triage steps (indexer lag, DB outages, RPC outages, etc.).

+# Docker Compose Setup for Vatix Backend
+
+This guide explains how to use Docker Compose to run the Vatix backend — either
+just the data layer (for host-run development) or the fully containerized stack.
+
+## Prerequisites
+
+- [Docker](https://docs.docker.com/get-docker/)
+- [Docker Compose](https://docs.docker.com/compose/install/)
+
+## Services
+
+| Service               | Profiles                                | Container name              | Notes                               |
+| --------------------- | --------------------------------------- | --------------------------- | ----------------------------------- |
+| `postgres`            | _(default)_                             | `vatix-postgres`            | PostgreSQL 16                       |
+| `redis`               | _(default)_                             | `vatix-redis`               | Redis 7 — caching + job queues      |
+| `api`                 | `app`, `api`                            | `vatix-backend`             | Fastify HTTP API, port 3000         |
+| `indexer`             | `app`, `indexer`                        | `vatix-indexer`             | Stellar event indexer               |
+| `finalization-worker` | `app`, `workers`, `finalization-worker` | `vatix-finalization-worker` | Resolution finalization loop        |
+| `oracle-worker`       | `app`, `workers`, `oracle-worker`       | `vatix-oracle-worker`       | Oracle submission queue consumer    |
+| `migrate`             | `tools`, `migrate`                      | `vatix-migrate`             | One-off `prisma migrate deploy` job |
+
+Container names match the ones referenced in
+[`docs/runbooks/incident-runbook.md`](runbooks/incident-runbook.md), so
+commands like `docker logs vatix-indexer` work as documented there.
+
+`postgres` and `redis` have no `profiles:` entry, so they always start by
+default — this preserves the original host-run development workflow below.
+Every application process lives behind a profile so you opt in explicitly.
+
+## Option A — Data layer only (host-run development)
+
+This is the original workflow: run infra in containers, run the app processes
+on the host with `tsx`.
+
+1. **Clone the repository and install dependencies:**
+
+   ```bash
+   git clone https://github.com/vatix-protocol/vatix-backend.git
+   cd vatix-backend
+   pnpm install
+   ```
+
+2. **Copy environment variables:**
+
+   ```bash
+   cp .env.example .env
+   ```
+
+   Edit `.env` if needed (see `.env.example` for details).
+
+3. **Start the data layer:**
+
+   ```bash
+   docker compose up -d
+   ```
+
+   This starts PostgreSQL (on port 5433) and Redis (on port 6379). No app
+   profile is requested, so only `postgres` and `redis` come up.
+
+4. **Initialize the database:**
+
+   ```bash
+   pnpm prisma:generate
+   pnpm prisma:migrate dev
+   ```
+
+5. **Run the backend processes on the host:**
+
+   ```bash
+   pnpm dev                          # API
+   pnpm indexer:dev                  # Indexer
+   pnpm workers:finalization:dev     # Finalization worker
+   pnpm workers:oracle:dev           # Oracle worker
+   ```
+
+## Option B — Full containerized stack
+
+Build and run every process as a container, using the `Dockerfile` at the repo
+root, which defines one build `--target` per process.
+
+1. **Copy environment variables** (same as above):
+
+   ```bash
+   cp .env.example .env
+   ```
+
+2. **Run database migrations** before starting the app processes for the
+   first time:
+
+   ```bash
+   docker compose --profile migrate up --build migrate
+   ```
+
+3. **Start everything:**
+
+   ```bash
+   docker compose --profile app up -d --build
+   ```
+
+   This builds and starts `postgres`, `redis`, `api`, `indexer`,
+   `finalization-worker`, and `oracle-worker`.
+
+   To run a subset, use the matching profile instead of `app`, e.g.:
+
+   ```bash
+   docker compose --profile api up -d --build      # postgres + redis + api only
+   docker compose --profile workers up -d --build  # postgres + redis + both workers
+   ```
+
+Inside the compose network, app containers reach Postgres/Redis via the
+service DNS names `postgres` and `redis` (not the host-mapped `localhost:5433`
+/ `localhost:6379` from `.env.example`) — `docker-compose.yml` overrides
+`DATABASE_URL` and `REDIS_URL` per service for this reason. Every other
+variable (API keys, Stellar config, log levels, etc.) is read from your local
+`.env` via `env_file`.
+
+## Stopping Services
+
+```bash
+docker compose --profile app down   # stop infra + app containers
+docker compose down                 # stop infra only
+```
+
+Add `-v` to also remove the `postgres_data` / `redis_data` volumes.
+
+## Useful Commands
+
+- View running containers:
+  ```bash
+  docker compose ps
+  ```
+- View logs for a specific process:
+  ```bash
+  docker compose logs -f api
+  docker logs vatix-indexer --tail 100 --follow
+  ```
+- Rebuild a single service after a code change:
+  ```bash
+  docker compose --profile app up -d --build api
+  ```
+
+## Graceful shutdown
+
+Every process registers `SIGINT`/`SIGTERM` handlers (see
+[Graceful Shutdown](graceful-shutdown.md)), and the Dockerfile sets
+`STOPSIGNAL SIGTERM`, so `docker compose stop` / `docker stop <container>`
+triggers the same clean shutdown path used for `Ctrl+C` in local development.

+# Environment Variable Validation
+
+This document describes how the `packages/shared` module validates environment
+variables at service startup, covering the two complementary utilities:
+`requireEnv` and `loadBaseConfig` / `loadIndexerConfig` / `loadFinalizationConfig`.
+
+## Overview
+
+All Vatix services validate their environment **at boot time** — not lazily at
+the point of first use. A missing or malformed variable causes an immediate,
+descriptive startup failure rather than a silent bug at runtime.
+
+Two utilities work together:
+
+| Utility                 | File                                | Purpose                        |
+| ----------------------- | ----------------------------------- | ------------------------------ |
+| `requireEnv()`          | `packages/shared/src/requireEnv.ts` | Fail-fast presence check       |
+| `loadBaseConfig()` etc. | `packages/shared/src/config.ts`     | Typed, validated config object |
+
+---
+
+## `requireEnv()`
+
+A lightweight guard that asserts every listed variable is present and non-empty.
+Call it once at the top of a service entry point before any other initialization.
+
+```ts
+import { requireEnv } from "@vatix/shared";
+
+requireEnv(["DATABASE_URL", "API_KEY", "REDIS_URL"]);
+```
+
+If any variable is missing the process exits immediately with code `1` and
+prints exactly which keys are absent:
+
+```
+[requireEnv] Missing required environment variables:
+  - API_KEY
+  - REDIS_URL
+```
+
+The function accepts an optional second argument for testing without touching
+real environment state:
+
+```ts
+requireEnv(["DATABASE_URL"], { DATABASE_URL: "postgresql://..." });
+```
+
+---
+
+## Typed Config Loaders
+
+`config.ts` exports three loader functions that read `process.env`, validate
+every field, and return a strongly-typed config object. Services pass this
+object around instead of accessing `process.env` directly.
+
+### `loadBaseConfig(env?)`
+
+Used by the API server and any service that shares the core stack.
+
+```ts
+import { loadBaseConfig } from "@vatix/shared";
+
+const config = loadBaseConfig(); // reads process.env
+```
+
+### `loadIndexerConfig(env?)`
+
+Used by `apps/indexer`.
+
+```ts
+import { loadIndexerConfig } from "@vatix/shared";
+
+const config = loadIndexerConfig();
+```
+
+### `loadFinalizationConfig(env?)`
+
+Used by `apps/workers` finalization worker.
+
+```ts
+import { loadFinalizationConfig } from "@vatix/shared";
+
+const config = loadFinalizationConfig();
+```
+
+All loaders accept an optional `env` parameter — a plain object — so they can
+be called in unit tests without mutating `process.env`.
+
+---
+
+## Validation Rules
+
+Each variable is validated according to its type. Invalid values throw a
+descriptive error that prevents startup.
+
+### Required strings
+
+Variables that must be present and non-empty. Missing value → startup failure.
+
+| Variable            | Used by      |
+| ------------------- | ------------ |
+| `DATABASE_URL`      | All services |
+| `STELLAR_RPC_URL`   | All services |
+| `ORACLE_SECRET_KEY` | API, Oracle  |
+| `API_KEY`           | API          |
+| `ADMIN_TOKEN`       | API          |
+
+**Error example:**
+
+```
+Missing required environment variable: API_KEY
+```
+
+### URL variables
+
+Must be a valid URL and use one of the accepted schemes.
+
+| Variable          | Accepted schemes               |
+| ----------------- | ------------------------------ |
+| `DATABASE_URL`    | `postgresql://`, `postgres://` |
+| `REDIS_URL`       | `redis://`, `rediss://`        |
+| `STELLAR_RPC_URL` | `https://`, `http://`          |
+
+**Error example:**
+
+```
+DATABASE_URL must use one of [postgresql:, postgres:], got: "mysql:"
+```
+
+### Enum variables
+
+Must be one of a fixed set of string values.
+
+| Variable                 | Accepted values                         | Default       |
+| ------------------------ | --------------------------------------- | ------------- |
+| `NODE_ENV`               | `development` \| `test` \| `production` | `development` |
+| `LOG_LEVEL`              | `debug` \| `info` \| `warn` \| `error`  | `info`        |
+| `ORACLE_LOG_LEVEL`       | `debug` \| `info` \| `warn` \| `error`  | `info`        |
+| `FINALIZATION_LOG_LEVEL` | `debug` \| `info` \| `warn` \| `error`  | `info`        |
+| `INDEXER_LOG_LEVEL`      | `debug` \| `info` \| `warn` \| `error`  | `info`        |
+
+**Error example:**
+
+```
+NODE_ENV must be one of development | test | production, got: "staging"
+```
+
+### Integer variables
+
+Must be a positive integer, optionally within a bounded range.
+
+| Variable                                 | Min  | Max     | Default |
+| ---------------------------------------- | ---- | ------- | ------- |
+| `PORT`                                   | 1    | 65535   | `3000`  |
+| `BODY_LIMIT_BYTES`                       | 1    | —       | `65536` |
+| `RATE_LIMIT_MAX`                         | 1    | —       | `100`   |
+| `RATE_LIMIT_WINDOW_MS`                   | 1    | —       | `60000` |
+| `RATE_LIMIT_HEAVY_MAX`                   | 1    | —       | `20`    |
+| `RATE_LIMIT_HEAVY_WINDOW_MS`             | 1    | —       | `60000` |
+| `RATE_LIMIT_WRITE_MAX`                   | 1    | —       | `10`    |
+| `RATE_LIMIT_WRITE_WINDOW_MS`             | 1    | —       | `60000` |
+| `ORACLE_POLL_INTERVAL_MS`                | 5000 | 3600000 | `30000` |
+| `ORACLE_CHALLENGE_WINDOW_SECONDS`        | 1    | —       | `86400` |
+| `FINALIZATION_INTERVAL_MS`               | 1000 | —       | `60000` |
+| `FINALIZATION_CHALLENGE_WINDOW_SECONDS`  | 0    | —       | `3600`  |
+| `INDEXER_INGESTION_INTERVAL_MS`          | 100  | —       | `5000`  |
+| `INDEXER_CHECKPOINT_FLUSH_EVERY_BATCHES` | 1    | —       | `10`    |
+
+**Error example:**
+
+```
+PORT must be a positive integer, got: "abc"
+PORT must be <= 65535, got: "99999"
+```
+
+### Optional strings with defaults
+
+These variables are safe to omit; a sensible default is used when absent.
+
+| Variable               | Default                                                                             |
+| ---------------------- | ----------------------------------------------------------------------------------- |
+| `STELLAR_NETWORK`      | `testnet`                                                                           |
+| `STELLAR_HORIZON_URL`  | `https://horizon-testnet.stellar.org`                                               |
+| `INDEXER_CURSOR_KEY`   | `ingestion`                                                                         |
+| `INDEXER_NETWORK_ID`   | `mainnet`                                                                           |
+| `CORS_ALLOWED_ORIGINS` | `http://localhost:3000,http://localhost:5173` (non-production) / empty (production) |
+
+### CORS origins
+
+`CORS_ALLOWED_ORIGINS` is a comma-separated list of allowed browser origins.
+
+```
+CORS_ALLOWED_ORIGINS=https://app.vatix.io,https://staging.vatix.io
+```
+
+In production, if this variable is not set, **no cross-origin requests are
+allowed**. In development and test the local dev server origins are permitted
+by default.

+The following variables are treated as secrets and are **never logged** in full,
+even at debug level:
+
+- `DATABASE_URL` (may contain password)
+- `REDIS_URL` (may contain password)
+- `ORACLE_SECRET_KEY`
+- `API_KEY`
+- `ADMIN_TOKEN`
+
+---
+
+## Adding a New Variable
+
+1. Add it to `.env.example` with a comment explaining purpose and whether it is required or optional.
+2. Add the validation call in the appropriate loader in `packages/shared/src/config.ts` using the existing helpers (`requireString`, `requirePositiveInt`, `loadUrl`, etc.).
+3. Add it to the relevant section of this document.
+4. If it is required at startup, add it to the `requireEnv()` call in the service entry point.
+
+---
+
+## Testing Config Loaders
+
+All loaders accept an optional `env` parameter, making them testable without
+touching `process.env`:
+
+```ts
+import { loadBaseConfig } from "@vatix/shared";
+
+it("throws when DATABASE_URL is missing", () => {
+  expect(() =>
+    loadBaseConfig({
+      NODE_ENV: "test",
+      STELLAR_RPC_URL: "https://soroban-testnet.stellar.org",
+      // DATABASE_URL intentionally omitted
+    })
+  ).toThrow("Missing required environment variable: DATABASE_URL");
+});
+```
+
+See `packages/shared/src/config.ts` for the full list of validation helpers.

+# Environment Variable Validation
+
+This document outlines how environment variables are validated within the Vatix Backend to ensure application stability and fail-fast behavior during startup.
+
+## Overview
+
+The Vatix Backend utilizes automated validation schemas to enforce that all required environment variables are present and correctly typed before the server fully initializes. This prevents runtime crashes caused by missing configurations.
+
+## Validation Layer
+
+We use a validation layer that checks configurations immediately upon initialization.
+
+### Key Checked Fields:
+
+- **Server Configurations:** `PORT`, `NODE_ENV`
+- **Database Credentials:** `DATABASE_URL`
+- **Authentication Keys:** `JWT_SECRET`
+
+## Local Setup
+
+1. **Copy the Template:** Always ensure your local `.env` file matches the structure defined in `.env.example`.
+2. **Missing Variables:** If a required variable is missing or fails validation, the application will log an error and terminate immediately on startup.
+
+---
+
+_For a full list of available keys, refer back to the root [README.md](../README.md)._

+# EventFetcher
+
+## Overview
+
+The `EventFetcher` class retrieves raw Soroban contract events from a Stellar RPC node. It is the
+first stage of the indexer pipeline — downstream parsers and the batch writer depend on the
+events it returns.
+
+## How it works
+
+1. The caller provides a `LedgerWindow` (start and end ledger sequence numbers).
+2. `fetchByLedgerWindow()` pages through `server.getEvents()` results, collecting every event
+   whose ledger falls within the requested window.
+3. Each RPC page is retried with exponential back-off when a transient error is detected
+   (network timeouts, 5xx responses). Non-transient errors propagate immediately.
+4. Raw `EventResponse` objects are mapped to `RawChainEvent` — a minimal, serialisation-safe
+   shape that downstream parsers consume.
+
+## Configuration
+
+`EventFetcher` is instantiated with an `EventFetcherConfig`:
+
+| Field          | Type     | Required | Default | Description                                   |
+| -------------- | -------- | -------- | ------- | --------------------------------------------- |
+| `rpcUrl`       | `string` | Yes      | —       | Stellar Soroban RPC endpoint URL              |
+| `contractId`   | `string` | Yes      | —       | Contract whose events are fetched              |
+| `maxRetries`   | `number` | No       | `3`     | Maximum retry attempts for transient failures  |
+| `retryDelayMs` | `number` | No       | `500`   | Base delay before first retry (doubles each)   |
+| `pageLimit`    | `number` | No       | `100`   | Events per RPC page request                    |
+
+## Retry strategy
+
+Retries use exponential back-off: `retryDelayMs * 2^attempt`. Only errors identified as
+transient by `isTransientError()` (from `retry.ts`) trigger a retry; all other errors are
+thrown immediately. After `maxRetries` consecutive transient failures the last error is
+re-thrown.
+
+## Telemetry
+
+Two metrics are recorded via the injected `Telemetry` interface:
+
+| Metric                      | Description                              |
+| --------------------------- | ---------------------------------------- |
+| `indexer.events.fetched`    | Total events returned for a ledger window |
+| `indexer.rpc.page_fetched`  | Events returned per RPC page              |
+| `indexer.rpc.error`         | Emitted when an RPC call fails terminally  |

+# Graceful Shutdown
+
+This document describes graceful shutdown patterns used across the Vatix backend to ensure clean resource cleanup and safe termination of services.
+
+## Overview
+
+Graceful shutdown ensures that services terminate safely by:
+
+1. **Stopping new work acceptance** — Prevents new requests/jobs from starting
+2. **Completing in-flight work** — Allows active operations to finish
+3. **Cleaning up resources** — Closes database connections, timers, and other resources
+4. **Exiting cleanly** — Exits the process with appropriate status code
+
+Without graceful shutdown, services risk data loss, incomplete transactions, and orphaned connections.
+
+## Signal Handling
+
+Unix signals (`SIGTERM`, `SIGINT`) are used to trigger graceful shutdown:
+
+| Signal  | Source              | Meaning                                |
+| ------- | ------------------- | -------------------------------------- |
+| SIGINT  | Ctrl+C in terminal  | Interrupt — user requested shutdown    |
+| SIGTERM | Docker/Kubernetes   | Terminate — system requested shutdown  |
+| SIGHUP  | Terminal disconnect | Hangup — terminal closed (use SIGTERM) |
+
+Both `SIGINT` and `SIGTERM` should be handled with the same graceful shutdown logic.
+
+## Workers Pattern
+
+The finalization worker (and similar workers) implements a standard graceful shutdown pattern:
+
+```typescript
+// 1. Flag to prevent concurrent shutdown attempts
+let isShuttingDown = false;
+
+// 2. Shutdown function handles cleanup
+const shutdown = async (signal: string) => {
+  // Prevent multiple concurrent shutdowns
+  if (isShuttingDown) return;
+  isShuttingDown = true;
+
+  logger.info("Shutting down", { signal, component: "worker" });
+
+  // 3. Stop accepting new work
+  clearInterval(timer); // Stop the job scheduler
+
+  // 4. Set hard timeout
+  const timeoutHandle = setTimeout(() => {
+    logger.error("Shutdown timeout exceeded, forcing exit");
+    process.exit(1);
+  }, SHUTDOWN_TIMEOUT_MS);
+
+  try {
+    // 5. Clean up resources
+    await disconnectPrisma();
+    clearTimeout(timeoutHandle);
+
+    logger.info("Shutdown complete", { component: "worker", exitCode: 0 });
+    process.exit(0);
+  } catch (error) {
+    clearTimeout(timeoutHandle);
+    logger.error("Shutdown failed", {
+      component: "worker",
+      exitCode: 1,
+      error: error.message,
+    });
+    process.exit(1);
+  }
+};
+
+// 6. Register signal handlers
+process.on("SIGINT", () => void shutdown("SIGINT"));
+process.on("SIGTERM", () => void shutdown("SIGTERM"));
+
+// 7. Start the worker
+await job.run();
+const timer = setInterval(() => void job.run(), intervalMs);
+```
+
+### Key Points
+
+1. **Flag Prevention**: Use a flag to prevent concurrent shutdown handlers from running simultaneously
+2. **Stop New Work**: Clear timers/intervals immediately to prevent new work from starting
+3. **Hard Timeout**: 30-second timeout prevents hanging on cleanup
+4. **Clean Resources**: Disconnect database clients, close connections, flush caches
+5. **Log Operations**: Log shutdown progress with component names for debugging
+6. **Exit Code**: Exit with 0 on success, 1 on failure
+7. **Void async handlers**: Use `void` to suppress unhandled promise warnings
+
+## Indexer Pattern
+
+The indexer service implements graceful shutdown with cursor checkpoint flushing:
+
+```typescript
+const shutdown = async (signal: string) => {
+  if (isShuttingDown) return;
+  isShuttingDown = true;
+
+  logger.info("Indexer shutdown initiated", {
+    signal,
+    component: "indexer",
+    status: "initiated",
+  });
+
+  const timeoutHandle = setTimeout(() => {
+    logger.error("Shutdown timeout exceeded, forcing exit", {
+      signal,
+      component: "indexer",
+      timeoutMs: SHUTDOWN_TIMEOUT_MS,
+    });
+    process.exit(1);
+  }, SHUTDOWN_TIMEOUT_MS);
+
+  try {
+    // Stop ingestion loop and FLUSH CHECKPOINT
+    await ingestionLoop.stop(); // Calls flushCheckpoint(true)
+    await disconnectPrisma();
+    clearTimeout(timeoutHandle);
+
+    logger.info("Indexer shutdown complete", {
+      signal,
+      component: "indexer",
+      status: "complete",
+      exitCode: 0,
+    });
+    process.exit(0);
+  } catch (error) {
+    clearTimeout(timeoutHandle);
+    logger.error("Indexer shutdown failed", {
+      signal,
+      component: "indexer",
+      status: "failed",
+      exitCode: 1,
+      error: error.message,
+    });
+    process.exit(1);
+  }
+};
+
+process.on("SIGINT", () => void shutdown("SIGINT"));
+process.on("SIGTERM", () => void shutdown("SIGTERM"));
+```
+
+### Checkpoint Flushing
+
+The `ingestionLoop.stop()` method ensures the current cursor position is flushed to storage before shutdown:
+
+```typescript
+async stop(): Promise<void> {
+  if (this.timer) {
+    clearInterval(this.timer);
+    this.timer = null;
+  }
+  if (this.heartbeatTimer) {
+    clearInterval(this.heartbeatTimer);
+    this.heartbeatTimer = null;
+  }
+
+  // Force flush checkpoint regardless of batch count
+  await this.flushCheckpoint(true);
+
+  logger.info("Indexer ingestion loop stopped", {
+    finalCursor: this.cursor,
+    latestIndexedLedgerSequence: this.metrics.getLatestIndexedLedgerSequence(),
+  });
+}
+```
+
+This ensures:
+
+- Current ledger position is persisted on SIGTERM
+- No data loss on container restart
+- Indexer resumes from last known position
+
+## API Server Pattern
+
+The HTTP API server (Fastify) has built-in graceful shutdown support. The API server now implements coordinated graceful shutdown:
+
+```typescript
+// Graceful shutdown handling
+const SHUTDOWN_TIMEOUT_MS = 30_000; // 30 seconds
+let isShuttingDown = false;
+
+const gracefulShutdown = async (signal: string) => {
+  if (isShuttingDown) {
+    return;
+  }
+  isShuttingDown = true;
+
+  server.log.info("API server shutdown initiated", {
+    signal,
+    component: "api-server",
+    status: "initiated",
+  });
+
+  // Set hard timeout to force exit if shutdown hangs
+  const timeoutHandle = setTimeout(() => {
+    server.log.error("Shutdown timeout exceeded, forcing exit", {
+      signal,
+      component: "api-server",
+      timeoutMs: SHUTDOWN_TIMEOUT_MS,
+    });
+    process.exit(1);
+  }, SHUTDOWN_TIMEOUT_MS);
+
+  try {
+    // Close server — stops accepting new connections, drains in-flight requests
+    await server.close();
+    clearTimeout(timeoutHandle);
+
+    server.log.info("API server shutdown complete", {
+      signal,
+      component: "api-server",
+      status: "complete",
+      exitCode: 0,
+    });
+    process.exit(0);
+  } catch (error) {
+    clearTimeout(timeoutHandle);
+    server.log.error("API server shutdown failed", {
+      signal,
+      component: "api-server",
+      status: "failed",
+      exitCode: 1,
+      error: error instanceof Error ? error.message : String(error),
+    });
+    process.exit(1);
+  }
+};
+
+process.on("SIGTERM", () => void gracefulShutdown("SIGTERM"));
+process.on("SIGINT", () => void gracefulShutdown("SIGINT"));
+```
+
+### Fastify Lifecycle
+
+- `server.close()` — Stops accepting new connections
+- Active HTTP connections are drained naturally
+- The server waits for in-flight requests to complete before closing
+- 30-second hard timeout prevents hanging on slow requests
+- Then exits cleanly
+
+## Database Connections
+
+All database connections must be closed during shutdown:
+
+```typescript
+import { getPrismaClient, disconnectPrisma } from "./services/prisma";
+
+// Disconnect the singleton Prisma client
+await disconnectPrisma();
+```
+
+The Prisma client handles:
+
+- Returning active connections to the pool
+- Closing the connection pool
+- Waiting for in-flight queries to complete (with timeout)
+
+**Timeout**: Prisma has a default 30-second timeout for connection cleanup.
+
+## Redis Connections
+
+If using Redis for caching or sessions:
+
+```typescript
+import redis from "./redis-client";
+
+// Close the Redis connection
+await redis.quit();
+
+// OR for connection pools:
+await redis.disconnect();
+```
+
+- `quit()` — Waits for pending commands, then closes
+- `disconnect()` — Closes immediately without waiting
+
+## Timeouts
+
+Add a hard timeout to prevent the process from hanging:
+
+```typescript
+const SHUTDOWN_TIMEOUT_MS = 30_000; // 30 seconds
+
+const gracefulShutdown = async (signal: string) => {
+  if (isShuttingDown) return;
+  isShuttingDown = true;
+
+  logger.info("Shutting down", { signal });
+
+  // Set a hard timeout to force exit if cleanup hangs
+  const timeoutHandle = setTimeout(() => {
+    logger.error("Shutdown timeout exceeded, forcing exit");
+    process.exit(1);
+  }, SHUTDOWN_TIMEOUT_MS);
+
+  try {
+    // Cleanup operations
+    await disconnectPrisma();
+    clearTimeout(timeoutHandle);
+
+    logger.info("Shutdown complete");
+    process.exit(0);
+  } catch (error) {
+    logger.error("Shutdown failed", { error: error.message });
+    process.exit(1);
+  }
+};
+```
+
+## Testing Graceful Shutdown
+
+### Docker/Kubernetes
+
+```bash
+# Send SIGTERM signal to the container
+docker stop <container> # Sends SIGTERM
+
+# Or:
+kubectl delete pod <pod> --grace-period=30
+```
+
+### Local Development
+
+```bash
+# Start the server
+npm run dev
+
+# In another terminal, send SIGTERM
+kill -TERM <pid>
+
+# Or press Ctrl+C (sends SIGINT)
+```
+
+### Verify Shutdown
+
+Check logs for:
+
+- `"Shutting down"` — Signal was received
+- `"Shutdown complete"` — Cleanup finished successfully
+- Exit code 0 — Process exited cleanly
+
+```bash
+# Check exit code of last command
+echo $?  # 0 = success, 1 = failure
+```
+
+## Worker Bootstrap Example
+
+Complete working example:
+
+```typescript
+import { Logger } from "@vatix/shared";
+import { getPrismaClient, disconnectPrisma } from "./services/prisma";
+
+interface JobConfig {
+  intervalMs: number;
+  logLevel: LogLevel;
+}
+
+async function bootstrap(): Promise<void> {
+  const config: JobConfig = loadConfig();
+  const logger = new Logger("MyWorker", config.logLevel);
+  const prisma = getPrismaClient();
+  const job = new MyJob(prisma, logger);
+
+  logger.info("Worker started", { interval: config.intervalMs });
+
+  // Run job once immediately
+  await job.run();
+
+  // Schedule recurring execution
+  const timer = setInterval(() => void job.run(), config.intervalMs);
+
+  let isShuttingDown = false;
+
+  const shutdown = async (signal: string) => {
+    if (isShuttingDown) return;
+    isShuttingDown = true;
+
+    logger.info("Worker shutting down", { signal });
+    clearInterval(timer); // Stop scheduler
+
+    try {
+      // Clean up resources
+      await disconnectPrisma();
+
+      logger.info("Worker shutdown complete");
+      process.exit(0);
+    } catch (error) {
+      logger.error("Worker shutdown failed", {
+        error: error instanceof Error ? error.message : String(error),
+      });
+      process.exit(1);
+    }
+  };
+
+  // Register signal handlers
+  process.on("SIGINT", () => void shutdown("SIGINT"));
+  process.on("SIGTERM", () => void shutdown("SIGTERM"));
+}
+
+// Start the worker
+void bootstrap().catch((error) => {
+  console.error("Bootstrap failed:", error);
+  process.exit(1);
+});
+```
+
+## Best Practices
+
+1. **Always register handlers** — Handle both SIGINT and SIGTERM
+2. **Use flags** — Prevent concurrent shutdown attempts
+3. **Log everything** — Include signal and completion status
+4. **Set timeouts** — Prevent hanging on cleanup
+5. **Test it** — Verify graceful shutdown works in your environment
+6. **Clean up resources** — Always disconnect database, cache, and other clients
+7. **Exit with status** — 0 for success, 1 for failure
+8. **Monitor exit codes** — Use process exit code for alerting and restarting
+
+## Environment Considerations
+
+### Local Development
+
+- Processes should exit immediately on Ctrl+C
+- Check logs to verify shutdown sequence
+
+### Docker
+
+- Docker sends SIGTERM on `docker stop` (default 10 second timeout)
+- Set container `stopSignal` to SIGTERM if needed
+- Verify shutdown completes within timeout
+
+The root [`Dockerfile`](../Dockerfile) sets this for every process target
+(`api`, `indexer`, `finalization-worker`, `oracle-worker`):
+
+```dockerfile
+# In Dockerfile
+STOPSIGNAL SIGTERM
+```
+
+Each entrypoint runs directly as PID 1 (no shell wrapper), so the signal
+reaches the process's `SIGTERM` handler immediately — see
+[docs/docker-compose.md](docker-compose.md) for how to run these containers.
+
+### Kubernetes
+
+- Pods receive SIGTERM on deletion
+- Grace period (default 30 seconds) allows shutdown
+- Configure health check to fail during shutdown
+
+```yaml
+# In pod spec
+terminationGracePeriodSeconds: 30
+lifecycle:
+  preStop:
+    exec:
+      command: ["/bin/sh", "-c", "sleep 5"]
+```
+
+### Process Managers
+
+- PM2, systemd, supervisor all support graceful restart
+- Ensure handler processes the correct signal
+- Verify exit code is used for restart logic
+
+## Troubleshooting
+
+### Process hangs on shutdown
+
+- Add shutdown timeout to force exit
+- Check logs for cleanup operation hanging
+- Review database/cache connection cleanup
+
+### Data loss on shutdown
+
+- Verify all in-flight operations complete before exiting
+- Check if transactions are being rolled back
+- Add pre-shutdown flush operations
+
+### Connections not closed
+
+- Check `disconnectPrisma()` is being called
+- Verify Redis/cache clients are disconnected
+- Use `lsof` to check open file descriptors
+
+```bash
+lsof -i -P -n | grep <process-name>
+```

+
+**DB write:** Currently logged via `logger.debug` only — no dedicated table exists yet. A future worker will reconcile collateral deposits into `UserPosition`. The idempotency key is stamped and the event passes through `indexerProcessedEvent` to prevent double-processing once a table is added.

+# Indexer Ledger Cursor
+
+## Overview
+
+The **ledger cursor** is the indexer's bookmark into the Stellar blockchain. It records the
+sequence number of the last ledger successfully processed so the indexer can resume from the
+correct position after a restart instead of re-scanning from genesis.
+
+## How it works
+
+1. On startup the indexer calls `PrismaCursorStorageClient.loadCursor()` to read the persisted
+   sequence number from the `indexer_cursors` table in PostgreSQL.
+2. Each ingestion tick fetches a ledger window via `EventFetcher`, parses events, writes them
+   through `PrismaBatchWriter`, and advances the in-memory cursor to the window end **only after
+   a successful batch write**.
+3. The cursor is flushed to PostgreSQL every `checkpointFlushEveryBatches` successful batches
+   (or immediately on shutdown).
+4. The cursor value is a plain decimal string matching the Stellar ledger sequence number
+   (e.g. `"1234567"`).
+
+## Database schema
+
+The cursor is stored in the `indexer_cursors` table with a composite primary key of
+`(network_id, cursor_key)`. This allows multiple indexer consumers to coexist on the same
+database — each with a distinct `cursor_key` — without clobbering one another.
+
+| Column         | Type   | Description                                                |
+| -------------- | ------ | ---------------------------------------------------------- |
+| `network_id`   | string | Stellar network identifier (e.g. `"testnet"`)              |
+| `cursor_key`   | string | Logical consumer name, configured via `INDEXER_CURSOR_KEY` |
+| `cursor_value` | string | Last processed ledger sequence number                      |
+
+Replay safety is provided by `indexer_processed_events.idempotency_key` (SHA-256 of
+`{contractId}:{ledger}:{txIndex}:{eventIndex}`). Re-processing ledgers between checkpoints
+inserts no duplicate rows.
+
+## Configuration
+
+| Variable                                 | Required | Default     | Description                                                                                                 |
+| ---------------------------------------- | -------- | ----------- | ----------------------------------------------------------------------------------------------------------- |
+| `INDEXER_CURSOR_KEY`                     | Optional | `ingestion` | Key used to namespace the cursor row. Change only when running multiple consumers against the same network. |
+| `INDEXER_CONTRACT_ID`                    | Required | —           | Soroban contract ID to ingest (also accepts `MARKET_CONTRACT_ID`).                                          |
+| `INDEXER_LEDGER_WINDOW_SIZE`             | Optional | `100`       | Ledgers scanned per ingestion tick.                                                                         |
+| `INDEXER_CHECKPOINT_FLUSH_EVERY_BATCHES` | Optional | `10`        | Successful batches between cursor checkpoints.                                                              |
+
+## Checkpoint flushing
+
+The cursor is not written to the database on every tick — frequent small writes would create
+unnecessary load. Instead it is flushed after a configurable number of successful batches
+(`INDEXER_CHECKPOINT_FLUSH_EVERY_BATCHES`) and unconditionally on graceful shutdown.
+
+## Recovery
+
+If the cursor row is absent (e.g. first run, or after manual deletion) the indexer starts from
+ledger 0 and scans forward. To reset the indexer to a specific ledger, delete or update the
+`indexer_cursors` row directly in PostgreSQL.
+
+**Crash between write and checkpoint:** Events in the un-checkpointed window are written to
+PostgreSQL (trades → `indexed_trades`, resolutions → `resolution_candidates`) but the cursor
+may still point to an earlier ledger. On restart the indexer re-fetches that window; duplicate
+events are skipped via `indexer_processed_events` idempotency keys (`skipped` count increments,
+no duplicate DB rows).
+
+```sql
+-- Reset to a specific ledger
+UPDATE indexer_cursors
+SET cursor_value = '1234567'
+WHERE network_id = 'testnet' AND cursor_key = 'ingestion';
+
+-- Remove the cursor entirely (restart from genesis)
+DELETE FROM indexer_cursors
+WHERE network_id = 'testnet' AND cursor_key = 'ingestion';
+```

+# Logger
+
+The logger module provides a lightweight, configurable logging utility for the Vatix backend.
+
+## Overview
+
+The `Logger` class is a structured logging interface that supports multiple log levels and message prefixing. It's designed to be simple and efficient without external dependencies.
+
+## Features
+
+- **Multiple Log Levels**: `debug`, `info`, `warn`, `error`
+- **Level Filtering**: Only logs messages at or above the configured level
+- **Message Prefixing**: Organize logs by component with optional prefixes
+- **Child Loggers**: Create hierarchical loggers for better organization
+- **Environment Configuration**: Configurable via `LOG_LEVEL` environment variable
+
+## Usage
+
+### Basic Logger Creation
+
+```typescript
+import { Logger } from "@vatix/shared";
+
+// Create a logger with optional prefix
+const logger = new Logger("MyComponent");
+
+// Log messages at different levels
+logger.debug("Debug information");
+logger.info("Information message");
+logger.warn("Warning message");
+logger.error("Error message");
+```
+
+### Log Levels
+
+The logger supports four levels, in order of severity:
+
+| Level | Usage                                    |
+| ----- | ---------------------------------------- |
+| debug | Detailed diagnostic information          |
+| info  | General informational messages (default) |
+| warn  | Warning conditions                       |
+| error | Error conditions                         |
+
+When you set a log level, only messages at that level or higher severity are logged:
+
+```typescript
+// With LOG_LEVEL=info, this is logged
+logger.info("This will be logged");
+
+// But this is not logged
+logger.debug("This will NOT be logged");
+```
+
+### Configuration via Environment Variable
+
+Set the `LOG_LEVEL` environment variable to control the global logging level:
+
+```bash
+# Only log info, warn, and error
+export LOG_LEVEL=info
+
+# Only log errors and warnings
+export LOG_LEVEL=warn
+
+# Log everything including debug
+export LOG_LEVEL=debug
+```
+
+**Default**: `info`
+
+If an invalid `LOG_LEVEL` is provided, a warning is written to stderr and the logger falls back to `info`.
+
+### Specifying Level in Constructor
+
+```typescript
+import { Logger } from "@vatix/shared";
+
+// Create logger with specific level (overrides env var)
+const debugLogger = new Logger("ComponentA", "debug");
+const errorLogger = new Logger("ComponentB", "error");
+```
+
+### Message Prefixes
+
+Prefixes help organize logs by component and source:
+
+```typescript
+const logger = new Logger("API");
+
+logger.info("Server starting");
+// Output: [API] Server starting
+
+const dbLogger = logger.child("Database");
+logger.info("Connected");
+// Output: [API:Database] Connected
+```
+
+### Child Loggers
+
+Create hierarchical loggers for better organization:
+
+```typescript
+const rootLogger = new Logger("App");
+const apiLogger = rootLogger.child("API");
+const marketLogger = apiLogger.child("Markets");
+
+marketLogger.info("Fetching markets");
+// Output: [App:API:Markets] Fetching markets
+```
+
+## Logger API
+
+### Constructor
+
+```typescript
+constructor(prefix: string = "", level?: LogLevel)
+```
+
+- `prefix`: Optional prefix for all messages from this logger
+- `level`: Optional log level (overrides `LOG_LEVEL` env var)
+
+### Methods
+
+#### `debug(msg: string): void`
+
+Log a debug-level message.
+
+```typescript
+logger.debug("Variable value: " + value);
+```
+
+#### `info(msg: string): void`
+
+Log an info-level message.
+
+```typescript
+logger.info("Operation completed successfully");
+```
+
+#### `warn(msg: string): void`
+
+Log a warning-level message.
+
+```typescript
+logger.warn("Retry attempt 3 of 5");
+```
+
+#### `error(msg: string): void`
+
+Log an error-level message.
+
+```typescript
+logger.error("Connection failed: " + error.message);
+```
+
+#### `child(childPrefix: string): Logger`
+
+Create a child logger with an extended prefix.
+
+```typescript
+const childLogger = logger.child("SubComponent");
+// Prefix will be: "ParentComponent:SubComponent"
+```
+
+Returns a new `Logger` instance that inherits the parent's log level.
+
+## Examples
+
+### API Route Logging
+
+```typescript
+import { Logger } from "@vatix/shared";
+
+const logger = new Logger("MarketsRoute");
+
+export async function getMarkets(request, reply) {
+  logger.info("GET /v1/markets request received");
+
+  try {
+    const markets = await fetchMarkets();
+    logger.debug(`Found ${markets.length} markets`);
+    return reply.send(markets);
+  } catch (error) {
+    logger.error(`Failed to fetch markets: ${error.message}`);
+    return reply.status(500).send({ error: "Internal server error" });
+  }
+}
+```
+
+### Background Worker Logging
+
+```typescript
+import { Logger } from "@vatix/shared";
+
+const logger = new Logger("SettlementWorker");
+
+async function processSettlements() {
+  logger.info("Starting settlement batch");
+
+  try {
+    const settlements = await getSettlements();
+    logger.debug(`Processing ${settlements.length} settlements`);
+
+    for (const settlement of settlements) {
+      try {
+        await execute(settlement);
+        logger.debug(`Settlement ${settlement.id} executed`);
+      } catch (error) {
+        logger.warn(`Settlement ${settlement.id} failed: ${error.message}`);
+      }
+    }
+
+    logger.info("Settlement batch completed");
+  } catch (error) {
+    logger.error(`Settlement batch failed: ${error.message}`);
+  }
+}
+```
+
+### Database Operations Logging
+
+```typescript
+import { Logger } from "@vatix/shared";
+
+const dbLogger = new Logger("Database");
+
+export class Repository {
+  private logger = dbLogger.child("OrderRepository");
+
+  async findOrder(id: string) {
+    this.logger.debug(`Querying order: ${id}`);
+    try {
+      const order = await db.order.findUnique({ where: { id } });
+      if (!order) {
+        this.logger.warn(`Order not found: ${id}`);
+      }
+      return order;
+    } catch (error) {
+      this.logger.error(`Query failed for order ${id}: ${error.message}`);
+      throw error;
+    }
+  }
+}
+```
+
+## Best Practices
+
+1. **Use Appropriate Levels**:
+   - `debug`: Development and troubleshooting only
+   - `info`: Important milestones and state changes
+   - `warn`: Recoverable issues and degraded conditions
+   - `error`: Failures and exceptions
+
+2. **Use Meaningful Prefixes**: Organize logs by component for easier debugging
+
+3. **Avoid Sensitive Data**: Never log passwords, API keys, or user credentials
+
+4. **Keep Messages Clear**: Use descriptive, human-readable messages
+
+5. **Use Child Loggers**: For nested components, use child loggers to maintain hierarchy
+
+## Internal Usage
+
+The shared module also exports a utility function for internal logging:
+
+```typescript
+import { log } from "@vatix/shared";
+
+log("message", value);
+// Output: [shared] message value
+```

+# Indexer Metrics Log
+
+The indexer emits a structured metrics snapshot log on a regular heartbeat interval and on shutdown. This document describes the shape and usage of that log.
+
+## Source
+
+`apps/indexer/src/metrics.ts` — `InternalIndexerMetricsService`
+
+## Log Event: `indexer.metrics.snapshot`
+
+Emitted via `toLogFields()` whenever the indexer logs its current metrics state (startup, heartbeat, shutdown).
+
+```json
+{
+  "event": "indexer.metrics.snapshot",
+  "latestIndexedLedgerSequence": 1234567
+}
+```
+
+| Field                         | Type                         | Description                                                                                                  |
+| ----------------------------- | ---------------------------- | ------------------------------------------------------------------------------------------------------------ |
+| `event`                       | `"indexer.metrics.snapshot"` | Fixed event tag for log filtering                                                                            |
+| `latestIndexedLedgerSequence` | `number \| null`             | Sequence number of the last successfully indexed Stellar ledger. `null` until the first ledger is processed. |
+
+## Snapshot
+
+`getSnapshot()` returns an `IndexerMetricsSnapshot` object for in-process use (e.g. health checks):
+
+```ts
+{
+  latestIndexedLedgerSequence: number | null;
+}
+```
+
+## Heartbeat
+
+The ingestion loop emits a heartbeat log every 60 seconds containing the metrics snapshot alongside cursor position and batch counts. Filter logs by `event: "indexer.heartbeat"` to track liveness.

+# Migration Rollback Procedure
+
+This document describes the safe rollback procedure for failed Prisma schema deployments.
+It should be followed whenever a migration fails in staging or production.
+
+---
+
+## Pre-Checks
+
+Before rolling back, confirm the following:
+
+1. **Identify the failed migration** — check which migration was last applied:
+
+   ```bash
+   pnpm prisma migrate status
+   ```
+
+2. **Assess data impact** — determine whether the failed migration added, altered, or dropped columns/tables.
+
+   > ⚠️ **Data-loss warning**: Rolling back a migration that dropped columns or tables is **not reversible** without a prior database backup. Always take a snapshot before deploying destructive migrations.
+
+3. **Verify a backup exists** — confirm a recent database dump is available before proceeding:
+
+   ```bash
+   pg_dump $DATABASE_URL > backup_$(date +%Y%m%d_%H%M%S).sql
+   ```
+
+4. **Stop application traffic** — scale down or put the API into maintenance mode to prevent writes during rollback.
+
+---
+
+## Rollback Command
+
+Prisma does not support automatic down-migrations. Rollback is performed by resolving the failed migration as rolled back and manually reverting the schema change.
+
+### Step 1 — Mark the failed migration as rolled back
+
+```bash
+pnpm prisma migrate resolve --rolled-back <migration_name>
+```
+
+Replace `<migration_name>` with the directory name under `prisma/migrations/`, e.g.:
+
+```bash
+pnpm prisma migrate resolve --rolled-back 20260427000000_add_market_status_created_at_index
+```
+
+### Step 2 — Manually revert the database change
+
+Apply the inverse SQL directly against the database. For example, to drop an index added by the failed migration:
+
+```bash
+psql $DATABASE_URL -c 'DROP INDEX IF EXISTS "markets_status_created_at_idx";'
+```
+
+> ⚠️ **Data-loss warning**: If the migration created a table or added a NOT NULL column with no default, reverting it will drop that table or column and any data it contains.
+
+### Step 3 — Revert the schema file
+
+Remove or undo the corresponding change in `prisma/schema.prisma` so the schema matches the rolled-back database state, then regenerate the client:
+
+```bash
+pnpm prisma:generate
+```
+
+---
+
+## Post-Checks
+
+After completing the rollback:
+
+1. **Confirm migration status is clean**:
+
+   ```bash
+   pnpm prisma migrate status
+   ```
+
+   Expected output: all applied migrations listed, no pending or failed entries.
+
+2. **Run the test suite** to confirm the application works against the rolled-back schema:
+
+   ```bash
+   pnpm test:run
+   ```
+
+3. **Restart the application** and verify the health endpoint responds correctly:
+
+   ```bash
+   curl http://localhost:3000/v1/health
+   # Expected: {"status":"ok","service":"vatix-backend",...}
+   ```
+
+4. **Restore application traffic** once health checks pass.
+
+---
+
+## Notes
+
+- Always test rollback procedures in **staging** before a production incident occurs.
+- Keep the `backup_*.sql` dump until the next successful deployment is confirmed.
+- For complex migrations (multi-step schema changes), consider splitting them into smaller, independently reversible migrations.

+# Database Migration Guide
+
+This document provides comprehensive instructions for managing database migrations in the vatix-backend project using Prisma.
+
+## Overview
+
+The vatix-backend uses **Prisma** as the database migration tool, which is already aligned with our PostgreSQL stack and provides type-safe database access.
+
+## Prerequisites
+
+- Node.js >= 18.0.0
+- PostgreSQL database
+- Environment variables configured (see `.env.example`)
+
+## Environment Setup
+
+Create a `.env` file based on `.env.example`:
+
+```bash
+cp .env.example .env
+```
+
+Ensure the following environment variables are set:
+
+```env
+# Database connection
+DATABASE_URL="postgresql://postgres:postgres@localhost:5432/vatix"
+
+# Redis (for production)
+REDIS_URL="redis://localhost:6379"
+
+# Node environment
+NODE_ENV="development"
+```
+
+## Migration Commands
+
+### Create New Migration
+
+To create a new migration after modifying `prisma/schema.prisma`:
+
+```bash
+# Generate migration file with descriptive name
+npm run prisma:migrate -- --name add_new_feature
+
+# Or using pnpm
+pnpm prisma:migrate -- --name add_new_feature
+```
+
+This will:
+
+1. Compare schema changes with current database state
+2. Generate migration SQL in `prisma/migrations/`
+3. Apply the migration to the database
+4. Generate updated Prisma Client
+
+### Apply Migrations (Production)
+
+To apply migrations without creating new ones (production deployment):
+
+```bash
+npm run prisma:migrate deploy
+# or
+pnpm prisma:migrate deploy
+```
+
+### Reset Database
+
+**⚠️ WARNING: This will delete all data**
+
+```bash
+npm run prisma:migrate reset
+# or
+pnpm prisma:migrate reset
+```
+
+### Generate Prisma Client
+
+After schema changes, regenerate the client:
+
+```bash
+npm run prisma:generate
+# or
+pnpm prisma:generate
+```
+
+### View Database
+
+Open Prisma Studio to inspect database content:
+
+```bash
+npm run prisma:studio
+# or
+pnpm prisma:studio
+```
+
+## Migration File Structure
+
+Migration files are stored in `prisma/migrations/` with timestamp prefixes:
+
+```
+prisma/migrations/
+├── 20260122080015_init/
+│   └── migration.sql
+├── 20260123090000_add_new_feature/
+│   └── migration.sql
+└── migration_lock.toml
+```
+
+### Migration File Naming
+
+- Use descriptive, snake_case names
+- Include timestamp automatically added by Prisma
+- Example: `add_user_preferences`, `create_order_indexes`
+
+## Best Practices
+
+### Schema Changes
+
+1. **Always review generated SQL** before applying
+2. **Test migrations on staging** before production
+3. **Use descriptive migration names**
+4. **Consider data preservation** for destructive changes
+
+### Migration Development
+
+1. **Make incremental changes** - one logical change per migration
+2. **Add indexes** for performance improvements
+3. **Use constraints** for data integrity
+4. **Document complex migrations** in comments
+
+### Production Deployment
+
+1. **Backup database** before major migrations
+2. **Test migrations** on staging environment
+3. **Use `migrate deploy`** (not `migrate dev`) in production
+4. **Monitor migration logs** for errors
+
+## CI/CD Integration
+
+The CI pipeline includes migration checks:
+
+```yaml
+# From .github/workflows/ci.yml
+- name: Run migrations
+  run: pnpm prisma:migrate deploy
+  env:
+    DATABASE_URL: postgresql://postgres:postgres@localhost:5432/vatix
+```
+
+### Migration Validation
+
+The project ships a dedicated validation script at [`scripts/validate-migrations.ts`](../scripts/validate-migrations.ts), run via:
+
+```bash
+pnpm prisma:validate
+```
+
+#### What it checks
+
+| Check                   | Description                                                               |
+| ----------------------- | ------------------------------------------------------------------------- |
+| Migration files present | Fails if `prisma/migrations/` contains no directories                     |
+| SQL readability         | Fails if any `migration.sql` cannot be read                               |
+| Dangerous operations    | Warns on `DROP TABLE`, `DROP COLUMN`, `DROP INDEX`, or bare `DELETE FROM` |
+| Schema sync             | Runs `prisma migrate diff` and fails if schema and migrations diverge     |
+| Client generation       | Runs `prisma generate` and fails if the Prisma client cannot be built     |
+
+Exit code `0` means all checks passed; exit code `1` means at least one error was found. Warnings are printed but do not cause failure.
+
+The script is executed in the GitHub Actions workflow before migrations are deployed, ensuring no schema drift is introduced by a pull request.
+
+## Common Migration Scenarios
+
+### Adding New Table
+
+```prisma
+model NewTable {
+  id        String   @id @default(uuid())
+  createdAt DateTime @default(now())
+
+  @@map("new_tables")
+}
+```
+
+### Adding New Column
+
+```prisma
+model Market {
+  // ... existing fields
+  newField String?
+}
+```
+
+### Adding Index
+
+```prisma
+model Market {
+  // ... existing fields
+
+  @@index([status, endTime])
+}
+```
+
+### Changing Column Type
+
+**⚠️ Requires careful planning for existing data**
+
+1. Create migration with type change
+2. Test data conversion
+3. Consider multi-step migration for complex changes
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Migration lock stuck**
+
+   ```bash
+   rm prisma/migrations/migration_lock.toml
+   ```
+
+2. **Database connection errors**
+   - Check `DATABASE_URL` format
+   - Verify PostgreSQL is running
+   - Check database exists
+
+3. **Schema drift**
+   ```bash
+   # Reset to match migration files
+   npx prisma migrate reset
+   ```
+
+### Getting Help
+
+- Check [Prisma Migration Docs](https://www.prisma.io/docs/concepts/components/prisma-migrate)
+- Review generated SQL before applying
+- Use `--preview-feature` flags for advanced features
+
+## Rollback Strategy
+
+Prisma doesn't support automatic rollbacks. Manual rollback process:
+
+1. **Create rollback migration**
+
+   ```bash
+   npx prisma migrate dev --name rollback_feature_name
+   ```
+
+2. **Manually write reverse SQL** in the migration file
+
+3. **Test rollback** thoroughly on staging
+
+## Migration Scripts
+
+The project includes several helpful scripts in `package.json`:
+
+```json
+{
+  "prisma:generate": "prisma generate",
+  "prisma:migrate": "prisma migrate dev",
+  "prisma:studio": "prisma studio",
+  "prisma:seed": "tsx prisma/seed.ts"
+}
+```
+
+## Seed Data
+
+To populate database with initial data:
+
+```bash
+npm run prisma:seed
+# or
+pnpm prisma:seed
+```
+
+This runs the seed script at `prisma/seed.ts` which can be customized for your needs.

+# Oracle Submission Pipeline
+
+## Overview
+
+The oracle submission pipeline provides a durable, Redis-backed system for resolving markets and submitting signed resolutions on-chain. It replaces the previous in-memory queue with a production-safe, at-least-once delivery system.
+
+## Architecture
+
+### Components
+
+1. **OracleService** (`apps/oracle/oracle-service.ts`)
+   - Resolves markets via primary/fallback providers
+   - Optional: enqueues successful resolutions for submission
+   - Tracks metrics (success/failure counts, retry attempts)
+
+2. **RedisSubmissionQueue** (`apps/workers/src/oracle/redis-submission-queue.ts`)
+   - Redis streams consumer group implementation
+   - Handles enqueue with deduplication
+   - Supports dequeue with visibility timeout
+   - Provides acknowledge/nack semantics for at-least-once delivery
+
+3. **SubmissionWorker** (`apps/workers/src/oracle/submission-worker.ts`)
+   - Polls the Redis queue for pending submissions
+   - Verifies signatures before submission
+   - Submits signed resolutions on-chain (via Stellar SDK)
+   - Updates OracleReport and ResolutionCandidate on success
+   - Implements retry logic with exponential backoff
+   - Dead-letters failed submissions after max retries
+
+4. **Oracle Worker Process** (`apps/workers/src/oracle/main.ts`)
+   - Entrypoint for the submission worker
+   - Manages bootstrap, polling loop, and graceful shutdown
+   - Handles SIGINT/SIGTERM signals
+
+## Deployment
+
+### Starting the Oracle Worker
+
+```bash
+# Development (watch mode with tsx)
+pnpm workers:oracle:dev
+
+# Production (single run)
+pnpm workers:oracle:start
+```
+
+### Environment Variables
+
+```env
+# Redis submission queue polling interval (ms)
+# Valid range: 1000-60000, Default: 5000
+ORACLE_SUBMISSION_POLL_INTERVAL_MS=5000
+
+# Max submission attempts before dead-lettering
+# Default: 3
+ORACLE_SUBMISSION_MAX_RETRIES=3
+
+# Visibility timeout for queued submissions (ms)
+# Default: 300000 (5 minutes)
+ORACLE_SUBMISSION_VISIBILITY_TIMEOUT_MS=300000
+
+# Log level for oracle worker (debug|info|warn|error)
+# Default: info
+ORACLE_SUBMISSION_LOG_LEVEL=info
+
+# Redis connection URL (required)
+REDIS_URL=redis://localhost:6379
+
+# PostgreSQL connection URL (required)
+DATABASE_URL=postgresql://postgres:postgres@localhost:5432/vatix
+
+# Stellar secret key for signing resolutions (required)
+ORACLE_SECRET_KEY=SAAA...
+
+# Challenge window duration for finalization (seconds)
+# Default: 86400 (24 hours)
+ORACLE_CHALLENGE_WINDOW_SECONDS=86400
+```
+
+## Data Flow
+
+### Resolution → Enqueue
+
+```
+OracleService.resolve()
+    ↓
+Provider returns ProviderResult
+    ↓
+enqueueCallback() / SubmissionQueue.enqueue()
+    ↓
+Compute payloadHash = SHA256(canonicalPayload)
+    ↓
+Check dedup key: oracle:dedup:{marketId}:{payloadHash}
+    ↓
+If exists: skip (already processed)
+If not exists:
+  - Add to Redis stream: oracle:submissions
+  - Set dedup flag with 24h TTL
+  - Log enqueue event
+```
+
+### Dequeue → Submit → Persist
+
+```
+Worker polls: xreadgroup(oracle-submissions, oracle-worker)
+    ↓
+Dequeue item from stream (visibility timeout: 5 min)
+    ↓
+Create SignedResolutionReport
+    ↓
+Verify signature (defensive check)
+    ↓
+submitOnChain() [placeholder for Stellar SDK]
+    ↓
+Success:
+  - Upsert OracleReport (status=SUBMITTED)
+  - Upsert ResolutionCandidate (status=PROPOSED)
+  - xack() to remove from queue
+  - Log success
+    ↓
+Failure (retryable):
+  - Increment attempts counter
+  - xclaim() to re-deliver message
+  - Log retry warning
+    ↓
+Failure (max retries exceeded):
+  - Mark OracleReport as FAILED
+  - xack() to remove from active queue
+  - Log dead-letter event
+```
+
+## Idempotency & Deduplication
+
+The system prevents duplicate submissions through:
+
+1. **Dedup Key**: `oracle:dedup:{marketId}:{payloadHash}`
+   - TTL: 86400 seconds (24 hours)
+   - Checked before enqueue; skip if exists
+
+2. **Payload Hash**: SHA256(JSON.stringify(canonicalPayload))
+   - Canonical ordering of payload fields ensures consistency
+   - Detects duplicate resolutions automatically
+
+3. **Visibility Timeout**: 300 seconds (5 minutes)
+   - Prevents "stuck" submissions from blocking the queue indefinitely
+   - Xclaim redelivers messages if worker crashes
+
+## Persistence
+
+### OracleReport Table
+
+Records signed resolutions submitted on-chain:
+
+```sql
+CREATE TABLE oracle_reports (
+  id UUID PRIMARY KEY,
+  market_id UUID NOT NULL,
+  payload_hash VARCHAR(64) NOT NULL,
+  source VARCHAR(256),         -- "oracle-service", "Chainlink", etc.
+  confidence DECIMAL(5, 4),    -- 0.0-1.0
+  candidate_resolution BOOLEAN, -- The proposed outcome
+  created_at TIMESTAMP DEFAULT NOW()
+);
+
+CREATE UNIQUE INDEX idx_oracle_reports_payload_hash_market
+ON oracle_reports(payload_hash, market_id);
+```
+
+### ResolutionCandidate Table
+
+Records proposed outcomes for finalization:
+
+```sql
+CREATE TABLE resolution_candidates (
+  id UUID PRIMARY KEY,
+  market_id UUID NOT NULL,
+  proposed_outcome BOOLEAN,
+  source VARCHAR(256),
+  status ResolutionCandidateStatus, -- PROPOSED, CHALLENGED, ACCEPTED, REJECTED
+  operator_address VARCHAR(56),     -- Oracle's Stellar public key
+  confidence_score DECIMAL(5, 4),
+  created_at TIMESTAMP,
+  updated_at TIMESTAMP
+);
+```
+
+## Failure Handling
+
+### Retryable Errors
+
+- Network timeouts
+- Transient Stellar RPC errors
+- Database connection failures
+
+**Action**: Increment attempt counter, xclaim to re-deliver
+
+### Non-Retryable Errors
+
+- Invalid signature
+- Market not found
+- Insufficient oracle balance on-chain
+- Invalid outcome value
+
+**Action**: Dead-letter immediately, record failure
+
+### Dead-Lettering
+
+Failed submissions that exceed `ORACLE_SUBMISSION_MAX_RETRIES` are:
+
+1. Marked as FAILED in OracleReport
+2. Removed from the active queue (xack)
+3. Logged with full error context
+4. Available for manual inspection via database queries
+
+## Monitoring & Observability
+
+### Key Metrics
+
+- **Queue Depth**: Number of pending submissions
+  - Query: `xinfo STREAM oracle:submissions`
+
+- **Consumer Lag**: Age of oldest unprocessed message
+  - Query: `xinfo GROUPS oracle:submissions`
+
+- **Submission Latency**: Time from enqueue to on-chain confirmation
+  - Source: OracleReport.created_at
+
+- **Error Rate**: Failed submissions / total submissions
+  - Source: logs with level=error
+
+### Logging
+
+All events are JSON-structured with:
+
+- `timestamp`: ISO 8601 timestamp
+- `level`: debug | info | warn | error
+- `message`: Human-readable summary
+- `marketId`: Associated market
+- `id`: Submission/report ID
+- `error`: Error message if failure
+- `attempt`: Current attempt number
+- `durationMs`: Processing time
+
+Example success log:
+
+```json
+{
+  "ts": "2024-06-16T12:34:56.789Z",
+  "level": "info",
+  "message": "Oracle submission processed successfully",
+  "id": "sub-123",
+  "marketId": "market-1",
+  "attempt": 1
+}
+```
+
+Example failure log:
+
+```json
+{
+  "ts": "2024-06-16T12:35:00.123Z",
+  "level": "warn",
+  "message": "Oracle submission processing failed, will retry",
+  "id": "sub-123",
+  "marketId": "market-1",
+  "attempt": 1,
+  "maxAttempts": 3,
+  "error": "Network timeout"
+}
+```
+
+## Runbook: On-Call Troubleshooting
+
+### Worker Not Processing Submissions
+
+1. **Check worker process**: `ps aux | grep oracle`
+   - If dead, restart: `pnpm workers:oracle:start`
+
+2. **Check Redis connection**:
+
+   ```bash
+   redis-cli -u $REDIS_URL ping
+   # Should return: PONG
+   ```
+
+3. **Check queue depth**:
+
+   ```bash
+   redis-cli -u $REDIS_URL XINFO STREAM oracle:submissions
+   # Look for: last-generated-id, length
+   ```
+
+4. **Check consumer group**:
+
+   ```bash
+   redis-cli -u $REDIS_URL XINFO GROUPS oracle:submissions
+   # Look for: consumers, pending
+   ```
+
+5. **Check logs**: `docker logs <oracle-worker-container>`
+
+### Stuck Submissions (Visibility Timeout)
+
+If a message remains pending > 5 minutes:
+
+1. **Manual claim back to active consumer**:
+
+   ```bash
+   redis-cli -u $REDIS_URL XCLAIM oracle:submissions oracle-worker consumer-1 0 {message-id}
+   ```
+
+2. **Or reset consumer group**:
+   ```bash
+   redis-cli -u $REDIS_URL XGROUP DESTROY oracle:submissions oracle-worker
+   # Then restart worker — it will recreate the group at "$" (latest)
+   ```
+
+### Database Out of Sync with Redis
+
+If OracleReport records exist without corresponding submissions:
+
+1. **Check dedup key**: `redis-cli KEYS "oracle:dedup:*"`
+   - If missing, enqueue is skipped due to dedup cache
+
+2. **Force reprocess**:
+
+   ```bash
+   # Delete dedup key to allow re-enqueue
+   redis-cli DEL oracle:dedup:{marketId}:{payloadHash}
+   ```
+
+3. **Manually enqueue**:
+   ```bash
+   redis-cli -u $REDIS_URL XADD oracle:submissions "*" \
+     payload '{"id":"...","request":{...},"result":{...},...}' \
+     marketId "market-1" \
+     payloadHash "abc123..."
+   ```
+
+## Testing
+
+### Unit Tests
+
+```bash
+# Run all oracle tests
+pnpm test -- apps/workers/src/oracle/
+
+# Run specific test file
+pnpm test -- redis-submission-queue.test.ts
+
+# With coverage
+pnpm test:coverage
+```
+
+### Integration Tests
+
+```bash
+# Run integration tests (requires Redis + PostgreSQL)
+pnpm test:integration
+
+# With detailed output
+pnpm test:integration -- --reporter=verbose
+```
+
+### Manual Testing
+
+1. **Start redis and PostgreSQL**:
+
+   ```bash
+   docker-compose up postgres redis
+   ```
+
+2. **Run migrations**:
+
+   ```bash
+   pnpm prisma:migrate
+   ```
+
+3. **Start oracle worker**:
+
+   ```bash
+   ORACLE_SUBMISSION_LOG_LEVEL=debug pnpm workers:oracle:dev
+   ```
+
+4. **Trigger resolution** (via API or direct call to OracleService)
+
+5. **Check Redis queue**:
+
+   ```bash
+   redis-cli -u $REDIS_URL XLEN oracle:submissions
+   redis-cli -u $REDIS_URL XRANGE oracle:submissions - +
+   ```
+
+6. **Monitor logs** for enqueue/dequeue events
+
+## Future Enhancements
+
+- [ ] Implement Stellar SDK integration for actual on-chain submission
+- [ ] Add batch submission (multiple resolutions in one transaction)
+- [ ] Implement circuit breaker for Stellar RPC failures
+- [ ] Add metrics export (Prometheus/Grafana)
+- [ ] Support for multiple oracle signers (threshold signatures)
+- [ ] On-chain transaction receipt tracking and verification

+# Orders Route
+
+The orders route lets clients create market orders and fetch a wallet's order
+history. Routes are implemented in `src/api/routes/orders.ts`.
+
+All public paths are mounted under `/v1`. Legacy root aliases redirect with
+deprecation headers during the compatibility window.
+
+## `GET /v1/orders/user/:address`
+
+Returns orders submitted by a Stellar wallet, sorted newest first.
+
+### Request
+
+Path parameters:
+
+| Field     | Type   | Required | Description                  |
+| --------- | ------ | -------- | ---------------------------- |
+| `address` | string | yes      | Stellar public key to query. |
+
+Query parameters:
+
+| Field    | Type   | Required | Description                                                  |
+| -------- | ------ | -------- | ------------------------------------------------------------ |
+| `status` | string | no       | One of `OPEN`, `FILLED`, `CANCELLED`, or `PARTIALLY_FILLED`. |
+| `page`   | number | no       | Page number, minimum `1`. Defaults to `1`.                   |

+
+### Response
+
+```json
+{
+  "orders": [
+    {
+      "id": "order-123",
+      "marketId": "market-1",
+      "userAddress": "G...",
+      "side": "BUY",

+    }
+  ],
+  "total": 1,
+  "hasNext": false,
+  "page": 1,
+  "limit": 20
+}
+```
+
+Common errors:
+
+| Status | Cause                                            |
+| ------ | ------------------------------------------------ |
+| `400`  | Invalid Stellar address, status, page, or limit. |
+| `500`  | Database lookup failed.                          |
+
+## `POST /v1/orders`
+
+Creates a new order after validating wallet ownership via Ed25519 signature,
+then checking the market state, price, quantity, side, and outcome.
+
+### Authentication
+
+Every `POST /v1/orders` request must carry two headers that prove the caller
+controls the Stellar wallet identified by `userAddress`.
+
+| Header        | Type   | Description                                                            |
+| ------------- | ------ | ---------------------------------------------------------------------- |
+| `x-timestamp` | string | Current Unix time in **milliseconds** as a decimal string.             |
+| `x-signature` | string | Base64-encoded Ed25519 signature of the canonical message (see below). |
+
+The server rejects requests whose `x-timestamp` differs from server time by
+more than **5 minutes** to prevent replay attacks.
+
+#### Canonical message
+
+Build the UTF-8 JSON string with the following keys in **alphabetical order**
+and sign its raw bytes with the wallet's Ed25519 private key:
+
+```json
+{
+  "marketId": "<marketId from body>",
+  "outcome": "<outcome from body>",
+  "price": <price from body>,
+  "quantity": <quantity from body>,
+  "side": "<side from body>",
+  "timestamp": <x-timestamp value as number>,
+  "userAddress": "<userAddress from body>"
+}
+```
+
+#### Example (TypeScript / `@stellar/stellar-sdk`)
+
+```typescript
+import { Keypair } from "@stellar/stellar-sdk";
+import { buildSignableMessage } from "src/api/middleware/stellarAuth";
+
+const keypair = Keypair.fromSecret("S...");
+const timestamp = Date.now();
+
+const body = {
+  marketId: "market-1",
+  userAddress: keypair.publicKey(),
+  side: "BUY",
+  outcome: "YES",
+  price: 0.6,
+  quantity: 100,
+};
+
+const message = buildSignableMessage({ ...body, timestamp });
+const signature = keypair.sign(message).toString("base64");
+
+fetch("/v1/orders", {
+  method: "POST",
+  headers: {
+    "Content-Type": "application/json",
+    "x-timestamp": String(timestamp),
+    "x-signature": signature,
+  },
+  body: JSON.stringify(body),
+});
+```
+
+### Request body
+
+```json

+  "userAddress": "G...",
+  "side": "BUY",
+  "outcome": "YES",
+  "price": 0.6,
+  "quantity": 100
+}
+```
+
+Fields:
+
+| Field         | Type   | Required | Description                              |
+| ------------- | ------ | -------- | ---------------------------------------- |

+# Price Fetcher
+
+The **Price Fetcher** is an internal component of the Oracle app that is responsible for retrieving external asset pricing data.
+
+## Overview
+
+The component securely and reliably requests live price feeds from registered external providers and returns structured responses with confidence scores.
+
+## Providers
+
+- **Primary Provider**: Used for the first attempt.
+- **Fallback Provider**: Kicks in automatically if the primary provider times out, fails authentication, or returns an invalid response.
+
+## Integration
+
+The price fetcher results are enqueued into the **Submission Queue** to be later signed and dispatched on-chain.

+# Queue Consumer
+
+This document describes the generic queue consumer used by the workers module.
+
+## Overview
+
+The queue consumer lives in `apps/workers/src/consumers/queue-consumer.ts`. It processes jobs from a named queue, handles retries, and dead-letters jobs that exhaust all attempts. All log output uses structured fields at appropriate log levels so it integrates cleanly with the project's JSON logging pipeline.
+
+## API
+
+### `QueueJob`
+
+Represents a single job pulled from the queue.
+
+| Field      | Type                      | Description                          |
+| ---------- | ------------------------- | ------------------------------------ |
+| `id`       | `string`                  | Unique job identifier                |
+| `payload`  | `Record<string, unknown>` | Arbitrary job data                   |
+| `attempts` | `number`                  | Delivery attempt count (starts at 1) |
+
+### `QueueConsumerConfig`
+
+Configuration passed to `processJob`.
+
+| Field                 | Type     | Description                                     |
+| --------------------- | -------- | ----------------------------------------------- |
+| `queueName`           | `string` | Logical queue name (e.g. `"settlement"`)        |
+| `maxAttempts`         | `number` | Maximum delivery attempts before dead-lettering |
+| `processingTimeoutMs` | `number` | Per-job processing timeout in milliseconds      |
+
+### `JobHandler`
+
+```typescript
+type JobHandler = (job: QueueJob) => Promise<void>;
+```
+
+An async function that receives a job and either resolves (success) or throws (failure).
+
+### `processJob(logger, config, job, handler)`
+
+Processes a single job with structured logging and retry semantics.
+
+```typescript
+import { processJob } from "./consumers/queue-consumer.js";
+
+await processJob(logger, config, job, async (job) => {
+  // handle job.payload
+});
+```
+
+## Log Levels
+
+| Event                          | Level   |
+| ------------------------------ | ------- |
+| Job received                   | `info`  |
+| Job completed successfully     | `info`  |
+| Failure with retries remaining | `warn`  |
+| Failure at max attempts        | `error` |
+
+## Retry and Dead-Letter Flow
+
+```
+Job received
+    │
+    ▼
+handler(job)
+    │
+    ├─ success ──► log info "Job processed successfully"
+    │
+    └─ error
+           │
+           ├─ attempts < maxAttempts ──► log warn "will retry", re-throw
+           │
+           └─ attempts >= maxAttempts ──► log error "max attempts exceeded", re-throw
+                                              │
+                                              ▼
+                                       logDeadLetter(...)
+```
+
+When `processJob` re-throws after the final attempt, the caller is responsible for invoking [`logDeadLetter`](dead-letter-log.md) to record the terminal failure.
+
+## Example
+
+```typescript
+import {
+  processJob,
+  type QueueConsumerConfig,
+  type QueueJob,
+} from "./consumers/queue-consumer.js";
+
+const config: QueueConsumerConfig = {
+  queueName: "settlement",
+  maxAttempts: 3,
+  processingTimeoutMs: 5_000,
+};
+
+const job: QueueJob = {
+  id: "job-001",
+  payload: { tradeId: "t-789" },
+  attempts: 1,
+};
+
+await processJob(logger, config, job, async (j) => {
+  // business logic here
+});
+```
+
+## Settlement Worker
+
+The settlement worker (`apps/workers/src/settlement/`) consumes the Redis settlement queue populated by `MatchingService` after each order match. It uses `processJob()` with dead-letter support and enforces idempotency on `tradeId`.
+
+### Environment Variables
+
+| Variable                | Default             | Description                           |
+| ----------------------- | ------------------- | ------------------------------------- |
+| `SETTLEMENT_QUEUE_NAME` | `settlement-trades` | Redis stream name for settlement jobs |
+| `REDIS_KEY_PREFIX`      | `vatix:`            | Key prefix applied to the stream name |
+
+### `SettlementJob` Payload
+
+| Field           | Type     | Description                               |
+| --------------- | -------- | ----------------------------------------- |
+| `tradeId`       | `string` | Unique trade identifier (idempotency key) |
+| `marketId`      | `string` | Market the trade occurred in              |
+| `outcome`       | `string` | Outcome side (`YES` / `NO`)               |
+| `buyOrderId`    | `string` | Taker or maker buy order ID               |
+| `sellOrderId`   | `string` | Taker or maker sell order ID              |
+| `buyerAddress`  | `string` | Stellar address of the buyer              |
+| `sellerAddress` | `string` | Stellar address of the seller             |
+| `price`         | `string` | Execution price (stringified)             |
+| `quantity`      | `string` | Matched quantity (stringified)            |
+| `timestamp`     | `string` | Unix epoch milliseconds (stringified)     |
+
+### Idempotency
+
+Before processing, the worker checks `settlement:processed:{tradeId}` in Redis. If the key exists the job is acknowledged and skipped. On successful processing the key is written with a 24-hour TTL so duplicate deliveries are silently discarded.
+
+### Flow
+
+```
+MatchingService.placeOrder()
+    │
+    └─ settlementQueue.enqueue(job)   ← fire-and-forget
+           │
+           ▼
+      Redis Stream (SETTLEMENT_QUEUE_NAME)
+           │
+           ▼
+      settlement consumer (XREADGROUP)
+           │
+           ├─ idempotency check (EXISTS settlement:processed:{tradeId})
+           │       └─ already processed → ACK, skip
+           │
+           └─ processJob() → handler
+                   ├─ success → SET idempotency key → ACK
+                   └─ error
+                         ├─ attempts < maxAttempts → warn, leave PENDING
+                         └─ attempts >= maxAttempts → logDeadLetter(), ACK
+```

+# Rate Limiting
+
+All API endpoints are protected by an in-memory, per-IP sliding-window rate
+limiter. Limits are tiered by endpoint cost so that expensive routes receive
+tighter controls without penalising cheap ones.
+
+## Tiers
+
+| Tier           | Default limit  | Env vars                                             | Applies to                        |
+| -------------- | -------------- | ---------------------------------------------------- | --------------------------------- |
+| **Global**     | 100 req / 60 s | `RATE_LIMIT_MAX`, `RATE_LIMIT_WINDOW_MS`             | Every route (baseline)            |
+| **Heavy read** | 20 req / 60 s  | `RATE_LIMIT_HEAVY_MAX`, `RATE_LIMIT_HEAVY_WINDOW_MS` | Expensive read routes (see below) |
+| **Write**      | 10 req / 60 s  | `RATE_LIMIT_WRITE_MAX`, `RATE_LIMIT_WRITE_WINDOW_MS` | Mutation routes (see below)       |
+| **Admin**      | 30 req / 60 s  | `RATE_LIMIT_ADMIN_MAX`, `RATE_LIMIT_ADMIN_WINDOW_MS` | All admin routes (see below)      |
+
+Each tier maintains its own counter, so exhausting the heavy-read budget does
+not consume the global budget and vice versa.
+
+## Route classification
+
+### Heavy read endpoints
+
+These routes perform expensive database operations on every call and are subject
+to the **heavy read** tier (20 req / 60 s per IP) in addition to the global baseline:
+
+| Route                               | Reason                                                     |
+| ----------------------------------- | ---------------------------------------------------------- |
+| `GET /v1/markets`                   | Full-table scan; no cursor-based pagination                |
+| `GET /v1/markets/:id/orderbook`     | `findMany` on open orders for a market                     |
+| `GET /v1/orders/user/:address`      | Two parallel DB queries (`findMany` + `count`)             |
+| `GET /v1/trades/user/:address`      | Two DB queries (trades `findMany` + audit join)            |
+| `GET /v1/wallets/:wallet/positions` | `findMany` with a `market` JOIN; optional order-book query |
+
+### Write endpoints
+
+Mutation routes carry the highest per-request cost (input validation, DB write,
+and matching-engine integration) and are subject to the **write** tier
+(10 req / 60 s per IP):
+
+| Route             | Reason                                              |
+| ----------------- | --------------------------------------------------- |
+| `POST /v1/orders` | Validation + DB write + matching-engine integration |
+
+### Admin endpoints
+
+Admin routes are privileged operations already gated behind API-key and
+admin-role checks. They are subject to the **admin** tier (30 req / 60 s per IP),
+which is stricter than the global baseline:
+
+| Route                                | Reason                                         |
+| ------------------------------------ | ---------------------------------------------- |
+| `GET /v1/admin/markets`              | Privileged full-table scan including cancelled |
+| `PATCH /v1/admin/markets/:id/status` | Privileged write — changes live market status  |
+
+### Standard endpoints
+
+All other routes are covered only by the global baseline (100 req / 60 s per IP):
+
+| Route                 | Notes                      |
+| --------------------- | -------------------------- |
+| `GET /v1/health`      | Lightweight liveness check |
+| `GET /v1/ready`       | Readiness check            |
+| `GET /v1/markets/:id` | Single-row point query     |
+
+## Response format
+
+Every response — including successful ones — carries quota-visibility headers
+so clients can self-throttle before hitting a limit:
+
+```
+RateLimit-Limit: 20
+RateLimit-Remaining: 17
+RateLimit-Reset: 1745798460
+```
+
+| Header                | Value                                                                      |
+| --------------------- | -------------------------------------------------------------------------- |
+| `RateLimit-Limit`     | Maximum requests allowed in the current window                             |
+| `RateLimit-Remaining` | Requests still available; `0` when the limit is reached                    |
+| `RateLimit-Reset`     | Unix timestamp (seconds UTC) when the window resets and the counter clears |
+
+Header names follow the [IETF RateLimit header fields draft](https://datatracker.ietf.org/doc/html/draft-ietf-httpapi-ratelimit-headers).
+
+When a limit is exceeded the server responds with HTTP **429 Too Many Requests**.
+The `Retry-After` header (seconds until reset) and all three quota headers are
+present on the 429 response as well:
+
+```json
+{
+  "error": "Too Many Requests",
+  "code": "RATE_LIMITED",
+  "statusCode": 429,
+  "retryAfter": 42
+}
+```
+
+## Configuration
+
+All limits are configurable via environment variables (see `.env.example`).
+Changes take effect on the next server start. The in-memory store resets on
+restart; for distributed deployments consider replacing the store with a shared
+Redis backend.
+
+| Env var                      | Tier       | Default |
+| ---------------------------- | ---------- | ------- |
+| `RATE_LIMIT_MAX`             | Global     | `100`   |
+| `RATE_LIMIT_WINDOW_MS`       | Global     | `60000` |
+| `RATE_LIMIT_HEAVY_MAX`       | Heavy read | `20`    |
+| `RATE_LIMIT_HEAVY_WINDOW_MS` | Heavy read | `60000` |
+| `RATE_LIMIT_WRITE_MAX`       | Write      | `10`    |
+| `RATE_LIMIT_WRITE_WINDOW_MS` | Write      | `60000` |
+| `RATE_LIMIT_ADMIN_MAX`       | Admin      | `30`    |
+| `RATE_LIMIT_ADMIN_WINDOW_MS` | Admin      | `60000` |
+
+## Integrator notes
+
+- Read `RateLimit-Remaining` on every response to track your remaining quota
+  before a 429 occurs. Back off proactively when it approaches zero.
+- When you do receive a 429, respect the `Retry-After` header (or equivalently
+  wait until the `RateLimit-Reset` Unix timestamp) before retrying.
+- The `X-Forwarded-For` header is used for IP detection when the server sits
+  behind a proxy. Ensure your proxy sets this header correctly.
+- Heavy and write limits are intentionally lower than the global limit. If your
+  integration requires higher throughput on these routes, contact the platform
+  team to discuss dedicated rate-limit tiers.
+- Admin limits are enforced before the API-key and admin-role checks, so
+  unauthenticated probes against admin routes still consume the admin quota.

+### Severity Decision Matrix
+
+Ask these questions to classify:
+
+1. **Is user data at risk?** → SEV-1
+2. **Are markets unable to resolve?** → SEV-1
+3. **Is the API completely down?** → SEV-1
+4. **Are >50% of requests failing?** → SEV-2
+5. **Is the indexer behind by >5 minutes?** → SEV-2
+6. **Are specific endpoints degraded?** → SEV-3

+
+## Incident 1: Indexer Lag or Stall
+
+### Symptoms
+
+- Indexer ingestion loop not progressing
+- `event_ingested` count not increasing
+- Cursor checkpoint not updating
+- Markets not appearing in database after on-chain creation
+- Trade events missing from order history
+
+### Detection
+
+```sql
+-- Check latest ingested event timestamp
+SELECT MAX(source_at) as latest_event FROM events;
+
+-- Check indexer cursor state
+SELECT * FROM indexer_cursors WHERE cursor_key = 'ingestion';
+
+-- Count events ingested in last hour
+SELECT COUNT(*) FROM events
+WHERE source_at > NOW() - INTERVAL '1 hour';
+```
+
+### Response Steps
+
+#### Step 1: Assess Current State
+
+```bash
+# Check indexer logs
+docker logs vatix-indexer --tail 100 --follow
+
+# Check if indexer process is running
+docker ps | grep indexer
+
+# Check cursor progression
+docker exec -it vatix-postgres psql -U postgres -d vatix -c \
+  "SELECT * FROM indexer_cursors WHERE cursor_key = 'ingestion';"
+```
+
+#### Step 2: Identify Root Cause
+
+**A. RPC/Horizon Connectivity Issues**
+
+```bash
+# Test Horizon connectivity
+curl -s https://horizon-testnet.stellar.org | jq .network
+
+# Check indexer config
+echo $INDEXER_INGESTION_INTERVAL_MS
+echo $STELLAR_HORIZON_URL
+```
+
+**B. Database Connection Issues**
+
+```bash
+# Test DB connectivity
+docker exec -it vatix-postgres pg_isready -U postgres
+
+# Check connection pool status in logs
+docker logs vatix-indexer 2>&1 | grep -i "connection\|pool\|error"
+```
+
+**C. Cursor Corruption or Invalid State**
+
+```sql
+-- Check cursor value
+SELECT network_id, cursor_key, cursor_value, updated_at
+FROM indexer_cursors
+WHERE cursor_key = 'ingestion';
+
+-- Compare with current Horizon ledger
+-- Visit: https://horizon-testnet.stellar.org/ledgers?order=desc&limit=1
+```
+
+#### Step 3: Remediation
+
+**A. Restart Indexer (First Attempt)**
+
+```bash
+# Graceful restart
+docker restart vatix-indexer
+
+# Monitor recovery
+docker logs vatix-indexer --tail 50 --follow
+```
+
+**B. Reset Cursor (If Corrupted)**
+
+```sql
+-- WARNING: Only if cursor is stuck on invalid ledger
+-- Get current ledger from Horizon first
+UPDATE indexer_cursors
+SET cursor_value = '[CURRENT_LEDGER - 100]',
+    updated_at = NOW()
+WHERE network_id = 'testnet' AND cursor_key = 'ingestion';
+```
+
+**C. Manual Event Backfill (If Gap Detected)**
+
+```bash
+# Run indexer in catch-up mode (if supported)
+# Or manually trigger ingestion cycle
+```
+
+#### Step 4: Verification
+
+```sql
+-- Confirm events are flowing
+SELECT COUNT(*) as events_last_5min
+FROM events
+WHERE source_at > NOW() - INTERVAL '5 minutes';
+
+-- Verify cursor is advancing
+SELECT network_id, cursor_key, cursor_value, updated_at
+FROM indexer_cursors
+WHERE cursor_key = 'ingestion';
+
+-- Check for recent market creations
+SELECT * FROM markets ORDER BY created_at DESC LIMIT 5;
+```
+
+#### Step 4b: Cursor Verification (Post-Deploy)
+
+After any deploy or restart, verify the cursor row is correctly persisted:
+
+```sql
+-- Confirm cursor_value is non-null and recently updated
+SELECT network_id, cursor_key, cursor_value, updated_at
+FROM indexer_cursors
+WHERE network_id = 'testnet' AND cursor_key = 'ingestion';
+-- Expected: cursor_value is a ledger sequence string (e.g. '1234567'), updated_at is recent
+
+-- If cursor_value is NULL or row is absent, the indexer will re-index from ledger 0.
+-- Insert a known-good starting ledger to avoid full re-scan:
+INSERT INTO indexer_cursors (network_id, cursor_key, cursor_value)
+VALUES ('testnet', 'ingestion', '[LAST_KNOWN_GOOD_LEDGER]')
+ON CONFLICT (network_id, cursor_key) DO UPDATE SET cursor_value = EXCLUDED.cursor_value;
+```
+
+#### Step 5: Prevention
+
+- [ ] Set up alerting on indexer lag > 2 minutes
+- [ ] Monitor cursor checkpoint age
+- [ ] Add Horizon health check to indexer loop
+- [ ] Implement automatic cursor rollback on RPC errors
+
+---
+
+## Incident 2: RPC/Horizon Outage
+
+### Symptoms
+
+- Indexer fails to fetch ledger data
+- Timeouts in event fetching
+- `503` or `504` errors from Horizon
+- Stale market data
+- Oracle unable to verify on-chain state
+
+### Detection
+
+```bash
+# Test Horizon endpoint
+curl -v https://horizon-testnet.stellar.org/ledgers?order=desc&limit=1
+
+# Check response time
+curl -w "@curl-format.txt" -o /dev/null -s https://horizon-testnet.stellar.org/
+
+# Monitor indexer error logs
+docker logs vatix-indexer 2>&1 | grep -i "timeout\|error\|503\|504"
+```
+
+### Response Steps
+
+#### Step 1: Confirm Outage Scope
+
+```bash
+# Test multiple Horizon endpoints
+curl -s https://horizon-testnet.stellar.org/ | jq .network
+curl -s https://horizon-testnet.stellar.org/accounts?limit=1 | jq -r '._links.self.href'
+
+# Check Stellar network status
+# Visit: https://status.stellar.org/
+# Check: https://stellarstatus.io/
+```
+
+#### Step 2: Assess Impact
+
+- **Indexer:** Will stall until RPC recovers (safe, will resume)
+- **API:** Can continue serving cached data
+- **Oracle:** May be unable to resolve markets if dependent on live data
+- **Trading:** Order matching continues (off-chain), but on-chain settlement delayed
+
+#### Step 3: Mitigation
+
+**A. Switch to Fallback RPC (If Available)**
+
+```bash
+# Update environment variable
+export STELLAR_HORIZON_URL=https://horizon-fallback.stellar.org
+
+# Restart indexer
+docker restart vatix-indexer
+```
+
+**B. Enable Graceful Degradation**
+
+```bash
+# If supported, enable cached mode
+export INDEXER_USE_CACHE=true
+
+# Alert users of degraded service
+# Update status page
+```
+
+**C. Pause Non-Critical Operations**
+
+```bash
+# Pause indexer if RPC completely down
+# to prevent error log flooding
+docker stop vatix-indexer
+
+# Resume when RPC recovers
+docker start vatix-indexer
+```
+
+#### Step 4: Monitor Recovery
+
+```bash
+# Continuously test RPC
+watch -n 5 'curl -s https://horizon-testnet.stellar.org/ledgers?order=desc&limit=1 | jq .[0].sequence'
+
+# Monitor indexer recovery
+docker logs vatix-indexer --tail 20 --follow
+```
+
+#### Step 5: Post-Recovery
+
+```sql
+-- Verify indexer caught up
+SELECT
+  MAX(source_at) as latest_event,
+  NOW() - MAX(source_at) as lag
+FROM events;
+
+-- Check for data gaps
+SELECT
+  ledger_sequence,
+  LAG(ledger_sequence) OVER (ORDER BY ledger_sequence) as prev_ledger,
+  ledger_sequence - LAG(ledger_sequence) OVER (ORDER BY ledger_sequence) as gap
+FROM events
+ORDER BY ledger_sequence DESC
+LIMIT 100;
+```
+
+#### Step 6: Prevention
+
+- [ ] Configure multiple RPC endpoints with failover
+- [ ] Implement circuit breaker pattern for RPC calls
+- [ ] Add RPC health monitoring and alerting
+- [ ] Set up Horizon status page webhook alerts
+
+---
+
+## Incident 3: Database Incident
+
+### Symptoms
+
+- Connection pool exhaustion
+- Query timeouts (> 30s)
+- Deadlocks detected
+- High CPU/memory on PostgreSQL
+- Prisma errors in application logs
+- Failed migrations
+
+### Detection
+
+```bash
+# Check PostgreSQL status
+docker exec -it vatix-postgres pg_isready -U postgres
+
+# Check container resource usage
+docker stats vatix-postgres --no-stream
+
+# Check PostgreSQL logs
+docker logs vatix-postgres --tail 100
+```
+
+### Response Steps
+
+#### Step 1: Assess Database Health
+
+```sql
+-- Check active connections
+SELECT count(*) as active_connections,
+       state
+FROM pg_stat_activity
+GROUP BY state;
+
+-- Check for long-running queries
+SELECT
+  pid,
+  now() - pg_stat_activity.query_start AS duration,
+  query,
+  state
+FROM pg_stat_activity
+WHERE (now() - pg_stat_activity.query_start) > interval '30 seconds'
+ORDER BY duration DESC;
+
+-- Check table sizes
+SELECT
+  schemaname,
+  tablename,
+  pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) AS size
+FROM pg_tables
+WHERE schemaname = 'public'
+ORDER BY pg_total_relation_size(schemaname||'.'||tablename) DESC;
+
+-- Check locks
+SELECT
+  blocked_locks.pid AS blocked_pid,
+  blocking_locks.pid AS blocking_pid,
+  blocked_activity.query AS blocked_query,
+  blocking_activity.query AS blocking_query
+FROM pg_catalog.pg_locks blocked_locks
+JOIN pg_catalog.pg_stat_activity blocked_activity ON blocked_activity.pid = blocked_locks.pid
+JOIN pg_catalog.pg_locks blocking_locks ON blocking_locks.locktype = blocked_locks.locktype
+JOIN pg_catalog.pg_stat_activity blocking_activity ON blocking_activity.pid = blocking_locks.pid
+WHERE NOT blocked_locks.granted;
+```
+
+#### Step 2: Immediate Remediation
+
+**A. Connection Pool Exhaustion**
+
+```sql
+-- Check pool status
+SELECT count(*) FROM pg_stat_activity;
+
+-- Kill idle connections if necessary
+SELECT pg_terminate_backend(pid)
+FROM pg_stat_activity
+WHERE state = 'idle'
+  AND now() - query_start > interval '5 minutes'
+  AND pid != pg_backend_pid();
+
+-- Check application connection pool settings
+# In .env: Ensure POOL_SIZE is appropriate
+# Default Prisma pool: 5-10 connections
+```
+
+**B. Kill Blocking Queries**
+
+```sql
+-- Identify the blocking query (from Step 1)
+-- Terminate if safe
+SELECT pg_terminate_backend([BLOCKING_PID]);
+
+-- WARNING: Only terminate if you understand the impact
+-- Never terminate: migration processes, oracle resolution transactions
+```
+
+**C. Database Restart (Last Resort)**
+
+```bash
+# Graceful shutdown
+docker stop vatix-postgres
+
+# Wait for clean shutdown
+docker logs vatix-postgres --tail 20
+
+# Start database
+docker start vatix-postgres
+
+# Verify recovery
+docker exec -it vatix-postgres pg_isready -U postgres
+
+# Restart dependent services
+docker restart vatix-backend
+docker restart vatix-indexer
+```
+
+#### Step 3: Disk Space Issues
+
+```bash
+# Check disk usage
+docker exec -it vatix-postgres df -h
+
+# Check database size
+docker exec -it vatix-postgres psql -U postgres -d vatix -c \
+  "SELECT pg_size_pretty(pg_database_size('vatix'));"
+
+# Clean up old data (if appropriate)
+# WARNING: Only delete if you have backups and understand retention requirements
+DELETE FROM events WHERE source_at < NOW() - INTERVAL '90 days';
+VACUUM ANALYZE events;
+```
+
+#### Step 4: Corruption or Data Loss
+
+```bash
+# Check database integrity
+docker exec -it vatix-postgres psql -U postgres -d vatix -c \
+  "SELECT * FROM pg_stat_user_tables WHERE n_dead_tup > 0;"
+
+# Restore from backup (if available)
+# See: docs/migration-rollback.md
+pg_restore -U postgres -d vatix backup_file.dump
+```
+
+#### Step 5: Verification
+
+```sql
+-- Test basic operations
+SELECT COUNT(*) FROM markets;
+SELECT COUNT(*) FROM events;
+SELECT COUNT(*) FROM indexer_cursors;
+
+-- Check query performance
+EXPLAIN ANALYZE SELECT * FROM markets WHERE status = 'active' LIMIT 10;
+
+-- Verify application connectivity
+# Check backend logs for Prisma errors
+docker logs vatix-backend --tail 50
+```
+
+#### Step 6: Prevention
+
+- [ ] Set up connection pool monitoring and alerting
+- [ ] Implement query performance monitoring
+- [ ] Configure automated backups (daily minimum)
+- [ ] Set up disk space alerts (>80% usage)
+- [ ] Add dead tuple monitoring and auto-vacuum tuning
+- [ ] Implement read replicas for heavy read workloads

+## Incident 4: Redis Failure
+
+### Symptoms
+
+- Rate limiting not working
+- Session/cache errors
+- Redis connection timeouts
+- `ECONNREFUSED` errors in logs
+
+### Detection
+
+```bash
+# Check Redis status
+docker exec -it vatix-redis redis-cli ping
+
+# Check Redis logs
+docker logs vatix-redis --tail 50
+
+# Check memory usage
+docker exec -it vatix-redis redis-cli INFO memory
+```
+
+### Response Steps
+
+#### Step 1: Assess Redis Health
+
+```bash
+# Test connectivity
+docker exec -it vatix-redis redis-cli ping
+# Expected: PONG
+
+# Check memory
+docker exec -it vatix-redis redis-cli INFO memory | grep used_memory_human
+
+# Check connected clients
+docker exec -it vatix-redis redis-cli INFO clients
+```
+
+#### Step 2: Restart Redis
+
+```bash
+# Graceful restart
+docker restart vatix-redis
+
+# Verify recovery
+docker exec -it vatix-redis redis-cli ping
+
+# Monitor logs
+docker logs vatix-redis --tail 20 --follow
+```
+
+#### Step 3: Clear Cache (If Corrupted)
+
+```bash
+# WARNING: This will clear all cached data including rate limits
+docker exec -it vatix-redis redis-cli FLUSHALL
+
+# Restart backend to reinitialize connections
+docker restart vatix-backend
+```
+
+#### Step 4: Verify Recovery
+
+```bash
+# Test rate limiting
+curl http://localhost:3000/v1/markets
+
+# Check backend logs for Redis errors
+docker logs vatix-backend 2>&1 | grep -i redis
+```
+
+#### Step 5: Prevention
+
+- [ ] Monitor Redis memory usage (alert at >75%)
+- [ ] Implement Redis persistence (RDB/AOF)
+- [ ] Add connection retry logic in application
+- [ ] Consider Redis Cluster for production
+

+
+## Incident 5: Oracle Resolution Failure
+
+### Symptoms
+
+- Market resolution stuck in `challenged` state
+- Oracle signing failures
+- Resolution candidates not being processed
+- Challenge window expiration without resolution
+
+### Detection
+
+```sql
+-- Check markets in challenged state
+SELECT
+  market_id,
+  status,
+  resolved_at,
+  challenge_ends_at,
+  NOW() - challenge_ends_at as time_since_challenge_end
+FROM markets
+WHERE status IN ('challenged', 'resolving')
+ORDER BY challenge_ends_at ASC;
+
+-- Check resolution candidates
+SELECT
+  market_id,
+  source_type,
+  confidence_score,
+  created_at
+FROM resolution_candidates
+ORDER BY created_at DESC
+LIMIT 20;
+```
+
+### Response Steps
+
+#### Step 1: Assess Oracle State
+
+```bash
+# Check oracle service logs
+docker logs vatix-backend 2>&1 | grep -i oracle
+
+# Verify oracle signing key is configured
+echo $ORACLE_SECRET_KEY
+
+# Test oracle endpoint (if available)
+curl http://localhost:3000/v1/oracle/health
+```
+
+#### Step 2: Manual Resolution (If Automated Fails)
+
+```sql
+-- WARNING: Only use manual resolution as last resort
+-- Requires admin access and proper authorization
+
+-- Update market status
+UPDATE markets
+SET status = 'resolved',
+    resolved_at = NOW(),
+    outcome = '[YES/NO]'
+WHERE market_id = '[MARKET_ID]';
+
+-- Log the manual intervention
+INSERT INTO audit_log (
+  action,
+  entity_type,
+  entity_id,
+  performed_by,
+  notes
+) VALUES (
+  'MANUAL_RESOLUTION',
+  'market',
+  '[MARKET_ID]',
+  '[ADMIN_ID]',
+  'Manual resolution due to oracle failure. Incident: [INCIDENT-ID]'
+);
+```
+
+#### Step 3: Verify Resolution
+
+```sql
+-- Confirm market status
+SELECT market_id, status, resolved_at, outcome
+FROM markets
+WHERE market_id = '[MARKET_ID]';
+
+-- Check positions are settled
+SELECT COUNT(*) as unsettled_positions
+FROM positions
+WHERE market_id = '[MARKET_ID]'
+  AND status != 'settled';
+```
+
+#### Step 4: Prevention
+
+- [ ] Implement oracle health monitoring
+- [ ] Add fallback oracle providers
+- [ ] Set up alerts for markets approaching challenge window expiry
+- [ ] Implement automatic retry with exponential backoff
+- [ ] Create manual resolution runbook with proper access controls

+the deprecated `/positions/user/:address` alias (see
+[docs/api-versioning.md](api-versioning.md)). PnL is opt-in via
+`?includePnl=true`; pricing requires an extra order-book query per market, so

+# Signature Helper
+
+The Oracle Signature Helper provides Ed25519 signing and verification utilities for oracle resolution reports. It uses the Stellar Keypair primitive, ensuring that the same key material works seamlessly with on-chain submission.
+
+## Resolution Payload
+
+The data payload that is signed for a resolution report includes:
+
+- `marketId`: The ID of the market being resolved.
+- `outcome`: The resolved outcome (`true` for YES, `false` for NO).
+- `timestamp`: ISO timestamp of the resolution.
+
+## Canonicalisation
+
+Before signing, the payload is converted into a deterministic canonical string. Keys are sorted so the same data always serializes identically.
+
+## Usage
+
+### Signing a Report
+
+```typescript
+import { signResolutionReport } from "../apps/oracle/signature-helper";
+
+const payload = {
+  marketId: "12345",
+  outcome: true,
+  timestamp: new Date().toISOString(),
+};
+
+const signedReport = signResolutionReport(
+  payload,
+  process.env.ORACLE_SECRET_KEY
+);
+```
+
+### Verifying a Report
+
+```typescript
+import { verifyResolutionReport } from "../apps/oracle/signature-helper";
+
+const isValid = verifyResolutionReport(signedReport);
+```

+
+### Auth guards
+
+`requireApiKey` checks the `x-api-key` header against `API_KEY` env var.  
+`requireAdmin` checks `Authorization: Bearer <token>` against `ADMIN_TOKEN` env var.  
+Admin routes require both. Tests cover: no headers → 401, API key only → 401, Bearer only → 401, wrong key → 401, wrong token → 403.
+
+### Shared test harness
+
+`tests/integration/helpers/build-test-app.ts` exports `buildTestApp({ plugins })` — builds a minimal Fastify instance with the real error handler, registers each plugin under `/v1`, sets `API_KEY`/`ADMIN_TOKEN` defaults.  
+Call `resetRateLimits()` from the same module in `beforeEach` to prevent rate-limit state bleeding between tests.
+
+### Required environment variables for integration tests
+
+```
+DATABASE_URL=postgresql://postgres:postgres@localhost:5432/vatix
+REDIS_URL=redis://localhost:6379
+NODE_ENV=test
+API_KEY=test-api-key          # set automatically by buildTestApp if absent
+ADMIN_TOKEN=test-admin-token  # set automatically by buildTestApp if absent
+```
+
+## Test Types
+
+### Unit Tests
+
+- Test individual functions and components in isolation
+- Use mocks for external dependencies
+- Fast execution, suitable for TDD
+
+### Integration Tests
+
+- Test API endpoints with real database
+- Use test database with deterministic fixtures
+- Slower but more comprehensive testing
+
+## Running Tests
+
+### Basic Commands
+
+```bash
+# Run all tests
+npm test
+# or
+pnpm test
+
+# Run tests in watch mode
+npm run dev
+# or
+pnpm dev
+
+# Run tests once (no watch)
+npm run test:run
+# or
+pnpm test:run
+
+# Run tests with coverage
+npm run test:coverage
+# or
+pnpm test:coverage
+
+# Run tests with UI
+npm run test:ui
+# or
+pnpm test:ui
+```
+
+### Running Specific Tests
+
+```bash
+# Run specific test file
+npm test markets.test.ts
+
+# Run tests matching pattern
+npm test -- --grep "markets"
+
+# Run tests in specific directory
+npm test tests/integration/
+```
+
+## Test Configuration
+
+The test configuration is in `vitest.config.ts`:
+
+- **Environment**: Node.js
+- **Pool**: Forks (for proper process isolation)
+- **Coverage**: V8 provider with 80% thresholds
+- **Setup**: Global setup file for test utilities
+- **Timeouts**: 30s test timeout, 10s hook timeout
+
+## Database Testing
+
+### Test Database Setup
+
+Tests use a dedicated test database with automatic cleanup:
+
+```typescript
+import { testUtils } from "../setup.js";
+
+// Create test data
+const market = await testUtils.createTestMarket();
+const position = await testUtils.createTestPosition(market.id, wallet);
+```
+
+### Database Utilities
+
+- `testUtils.createTestMarket()` - Create test market
+- `testUtils.createTestPosition()` - Create test position
+- `testUtils.createTestOrder()` - Create test order
+- `testUtils.generateStellarAddress()` - Generate valid address
+- `testUtils.assertDecimalEqual()` - Fixed-precision assertions
+
+### Test Isolation
+
+- Database is cleaned before each test
+- Advisory locks serialize database tests
+- Each test gets fresh data
+
+## Writing Tests
+
+### Test Structure
+
+```typescript
+import { describe, it, expect, beforeEach, afterEach } from "vitest";
+import { testUtils } from "../setup.js";
+
+describe("Feature Name", () => {
+  beforeEach(async () => {
+    // Setup before each test
+  });
+
+  afterEach(async () => {
+    // Cleanup after each test
+  });
+
+  it("should do something", async () => {
+    // Arrange
+    const testData = await testUtils.createTestMarket();
+
+    // Act
+    const result = await someFunction(testData.id);
+
+    // Assert
+    expect(result).toBeDefined();
+    expect(result.status).toBe("ACTIVE");
+  });
+});
+```
+
+### Best Practices
+
+1. **Use descriptive test names** - "should return 400 for invalid input"
+2. **Follow AAA pattern** - Arrange, Act, Assert
+3. **Test one thing per test** - Single assertion per test when possible
+4. **Use helpers for setup** - Leverage `testUtils` for common operations
+5. **Mock external services** - Use mocks for third-party APIs
+6. **Test edge cases** - Empty data, invalid inputs, error conditions
+
+### Integration Tests
+
+For API endpoint testing:
+
+```typescript
+import Fastify from "fastify";
+import { describe, it, expect } from "vitest";
+
+describe("API Endpoint", () => {
+  let app: FastifyInstance;
+
+  beforeAll(async () => {
+    app = Fastify({ logger: false });
+    await app.register(routes);
+  });
+
+  afterAll(async () => {
+    await app.close();
+  });
+
+  it("should return correct response", async () => {
+    const response = await app.inject({
+      method: "GET",
+      url: "/endpoint",
+    });
+
+    expect(response.statusCode).toBe(200);
+    const body = JSON.parse(response.body);
+    expect(body).toHaveProperty("data");
+  });
+});
+```
+
+## Coverage
+
+### Coverage Configuration
+
+Coverage is configured with 80% thresholds for:
+
+- Branches
+- Functions
+- Lines
+- Statements
+
+### Viewing Coverage Reports
+
+```bash
+# Generate coverage report
+npm run test:coverage
+
+# View HTML report (opens in browser)
+open coverage/index.html
+```
+
+### Coverage Exclusions
+
+The following are excluded from coverage:
+
+- Test files (`**/*.test.ts`, `**/*.spec.ts`)
+- Test directories (`tests/`)
+- Scripts (`scripts/`)
+- Coverage reports (`coverage/`)
+
+## Test Data Management
+
+### Deterministic Fixtures
+
+Tests use deterministic fixtures for stable outcomes:
+
+```typescript
+// Generate consistent test data
+const testWallet = testUtils.generateStellarAddress("GTEST");
+const testMarket = await testUtils.createTestMarket({
+  question: "Predictable test question",
+  endTime: new Date("2026-12-31T23:59:59Z"),
+});
+```
+
+### Data Cleanup
+
+Database is automatically cleaned between tests:
+
+```typescript
+// Automatic cleanup in beforeEach
+beforeEach(async () => {
+  await cleanDatabase();
+});
+```
+
+## Mock Testing
+
+### Mocking Dependencies
+
+```typescript
+import { vi } from "vitest";
+
+// Mock entire module
+vi.mock("../../services/prisma.js", () => ({
+  getPrismaClient: () => mockPrismaClient,
+}));
+
+// Mock specific function
+const mockFunction = vi.fn();
+vi.mock("../../module", () => ({
+  functionName: mockFunction,
+}));
+```
+
+### Mock Assertions
+
+```typescript
+// Verify mock was called
+expect(mockFunction).toHaveBeenCalled();
+expect(mockFunction).toHaveBeenCalledWith(expectedArgs);
+
+// Clear mocks between tests
+beforeEach(() => {
+  vi.clearAllMocks();
+});
+```
+
+## Performance Testing
+
+### Test Performance
+
+Vitest provides built-in performance tracking:
+
+```typescript
+import { bench } from "vitest";
+
+bench("function performance", () => {
+  // Function to benchmark
+  expensiveFunction();
+});
+```
+
+## Continuous Integration
+
+### CI Test Configuration
+
+Tests run in CI with:
+
+```yaml
+# From .github/workflows/ci.yml
+- name: Run tests
+  run: pnpm test
+  env:
+    DATABASE_URL: postgresql://postgres:postgres@localhost:5432/vatix
+    REDIS_URL: redis://localhost:6379
+    NODE_ENV: test
+
+- name: Run tests with coverage
+  run: pnpm test:coverage
+  env:
+    DATABASE_URL: postgresql://postgres:postgres@localhost:5432/vatix
+    REDIS_URL: redis://localhost:6379
+    NODE_ENV: test
+```
+
+### Coverage Upload
+
+Coverage reports are automatically uploaded to Codecov.
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Database connection errors**
+   - Check `DATABASE_URL` environment variable
+   - Ensure PostgreSQL is running
+   - Verify test database exists
+
+2. **Test timeouts**
+   - Increase timeout in `vitest.config.ts`
+   - Check for infinite loops or hanging promises
+
+3. **Mock issues**
+   - Clear mocks in `beforeEach`
+   - Verify mock configuration
+   - Check module path resolution
+
+4. **Coverage issues**
+   - Check exclusion patterns
+   - Verify thresholds are realistic
+   - Ensure all code paths are tested
+
+### Debugging Tests
+
+```bash
+# Run tests with debugger
+node --inspect-brk node_modules/.bin/vitest
+
+# Run specific test with logging
+DEBUG=* npm test -- specific-test.test.ts
+```
+
+## Best Practices Summary
+
+1. **Write tests first** (TDD when possible)
+2. **Keep tests fast** - Use mocks for external dependencies
+3. **Test edge cases** - Don't just test happy paths
+4. **Use descriptive names** - Test should document behavior
+5. **Maintain test independence** - Tests shouldn't depend on each other
+6. **Review coverage reports** - Aim for meaningful coverage, not just metrics
+7. **Update tests with code** - Keep tests in sync with implementation

+# Database Migrations - Positions Table
+
+## Migration: Add Positions Table
+
+**Migration ID:** `20260427000001_add_positions_table`
+
+### Overview
+
+This migration creates a `positions` table for wallet market positions snapshot/projection.
+The table is designed for fast position queries using optimized read storage.
+
+### Strategy: Snapshot vs Event-Derived
+
+This migration implements a **snapshot-based strategy**:
+
+- **Positions table** stores the current state of each wallet's position in a market.
+- It is updated via **upsert** operations from the indexer whenever a trade occurs.
+- This provides fast reads at the cost of slightly more complex writes.
+- An alternative **event-derived strategy** would compute positions from trade events at query time, which saves storage but is slower for reads.
+
+The snapshot strategy was chosen because:
+
+1. Position queries are read-heavy (users frequently check their positions)
+2. Snapshot reads are O(1) vs O(n) for event-derived
+3. Upsert operations are idempotent and safe
+
+### Table Structure
+
+| Column         | Type          | Description                                 |
+| -------------- | ------------- | ------------------------------------------- |
+| id             | UUID          | Primary key                                 |
+| wallet_address | VARCHAR(56)   | Stellar wallet address                      |
+| market_id      | UUID          | Associated market                           |
+| outcome        | Outcome       | YES or NO (nullable for combined positions) |
+| quantity       | INTEGER       | Number of shares held                       |
+| valuation      | DECIMAL(20,8) | Current valuation in base currency          |
+| created_at     | TIMESTAMP     | When the position was first created         |
+| updated_at     | TIMESTAMP     | When the position was last updated          |
+
+### Indexes
+
+- `positions_wallet_address_idx` - Fast lookup by wallet
+- `positions_market_id_idx` - Fast lookup by market
+- `positions_wallet_market_outcome_idx` - Unique constraint for upsert

+# Scripts
+
+Dev utilities for bootstrapping, database management, and maintenance tasks.
+
+## Conventions
+
+- Scripts are TypeScript, executed via `tsx` (no compile step needed)
+- Add new scripts here rather than documenting one-off shell commands in chat
+- Prefer shell-agnostic implementations; avoid bash-only syntax
+- Scripts must be safe to run locally and in CI
+
+## Execution
+
+Run any script with:
+
+```bash
+npx tsx scripts/<script-name>.ts
+# or via pnpm if a package.json script alias exists
+pnpm <alias>
+```
+
+Scripts that require environment variables will fail fast with a clear error if they are missing. Copy `.env.example` to `.env` before running locally.
+
+## Available Scripts
+
+| Script                   | pnpm alias              | Purpose                                            |
+| ------------------------ | ----------------------- | -------------------------------------------------- |
+| `generate-keypair.ts`    | `pnpm generate:keypair` | Generate a Stellar keypair for oracle signing      |
+| `validate-migrations.ts` | `pnpm prisma:validate`  | Validate Prisma migration files against the schema |
+
+## Adding a Script
+
+1. Create `scripts/<your-script>.ts`
+2. Add a `pnpm` alias in `package.json` under `scripts` if it will be run frequently

+ *   - Readiness (GET /v1/ready):  the process can serve valid data. Fails
+ *     when a critical dependency (DB, index freshness) is unavailable.
