Summary

Implements all P0/P1/P2 findings from the business logic quality audit to bring the platform from 72/100 to production-ready.

P0 — Critical (double-spend prevention):

All wallet mutations now use atomic SQL:

UPDATE wallet_balances
SET balance = (CAST(balance AS DECIMAL(30,8)) - $amount)::TEXT
WHERE user_id = $userId AND currency = $currency
  AND CAST(balance AS DECIMAL(30,8)) >= $amount
RETURNING id, balance

Applied to: wallet.send, wallet.sendCrossCurrency, wallet.swap, wallet.convertCurrency, qrPayment.pay, meshPayments.send, sustainability.purchaseOffset

setTimeout-based settlement/remittance completion replaced with scheduled_jobs table insert (durable across restarts).

Idempotency keys added to wallet.send and wallet.swap via optional idempotencyKey: z.string().uuid() param — duplicate requests return the original txId.

P1:

  • merchantRevenue.summary: in-memory aggregation → SQL SUM()/COUNT(*)
  • touristPortal.createBooking: slot deduction now UPDATE ... WHERE booked_slots < total_slots
  • fraudRouter.create/resolve/markFalsePositiveadminProcedure

P2:

  • sustainability.purchaseOffset now deducts USDC from wallet
  • embeddedFinance.applyForLoan enforces max 3 active loans
  • Fixed missing await on listSettlements query builder
  • Replaced all throw new Error() with TRPCError in 9 routers

TypeScript: 0 errors.

…on, analytics guard

- Add /api/demo-login unified endpoint supporting ?role=admin|tourist|merchant|compliance_officer|settlement_officer|noc_operator|bis_analyst
- Fix auth session verification: allow empty appId string (was rejecting all demo logins)

- Fix getLoginUrl() fallback to use /api/demo-login?role=tourist
- Guard analytics script to only load when VITE_ANALYTICS_* env vars are configured
- All demo login roles now properly set user role in DB and mark onboarding complete

Co-Authored-By: Patrick Munis <pmunis@gmail.com>
CRITICAL:
1. Split psStubs.ts (1,602 lines) into 11 domain-specific router files
2. Add requireDb() for proper error propagation (replaces silent getDbOrNull)
3. JWT secret: env-based with production enforcement (>= 32 chars)
4. CSRF protection middleware with SameSite strict cookies
5. Replace all Math.random() IDs with crypto.randomUUID()

HIGH:
6. Frontend component tests (TouristOnboarding, RoleNavigation, DigitalWallet)
7. i18n framework with 5 languages (EN/FR/PT/SW/AR)
8. Accessibility: SkipToMain, LiveRegion, useFocusTrap, ARIA landmarks
9. Email/phone verification router with timing-safe code validation
10. Structured JSON logging with request correlation IDs

MEDIUM:
11. Express-level rate limiting (per-IP with route-specific tiers)
12. Database connection pooling (max 20 prod, 10 dev, 30min lifetime)
13. Service worker v5.0: CacheFirst/NetworkFirst/StaleWhileRevalidate strategies
14. S3 storage service for KYB document uploads (with local fallback)
15. Database backup script (pg_dump + S3 + verification)

LOW:
16-18. OpenAPI docs generator, migration drift CI check scripts
19. Web Vitals / APM monitoring (LCP, FID, CLS, TTFB, INP)
20. Cross-platform feature parity matrix (PWA vs RN vs Flutter)

TypeScript typecheck: 0 errors

CRITICAL fixes:
- Install cookie-parser and wire into pipeline for CSRF double-submit pattern
- Wire corsHardeningMiddleware into Express pipeline (was defined but unmounted)
- Fix PBAC ordering: moved from Express middleware to tRPC middleware layer
  so it runs AFTER auth context is available (ctx.user was always undefined)
- Consolidate duplicate rate limiters: DDoS protection handles content inspection,
  rateLimiter.ts handles all rate limiting (no more conflicting X-RateLimit headers)
- DDoS protection: content inspection and ransomware detection always active,
  only rate limiting portion skipped in development mode

HIGH priority:
- Circuit breaker for all downstream service calls (PBAC, settlement, ML, Redis,
  Kafka, Temporal, OpenSearch, etc.) with configurable thresholds per service
- Redis session caching for auth (60s TTL, in-memory fallback when Redis unavailable)
- Per-route body size limits (1MB default, 50MB for KYB document uploads)
- Kafka producer for domain events via Dapr sidecar (fire-and-forget with circuit breaker)
- Graceful shutdown handler: stops accepting connections, drains in-flight requests,
  stops background jobs, closes DB pool on SIGTERM/SIGINT

MEDIUM priority:
- Request ID propagation to downstream services via serviceFetch wrapper
- Temporal typed client for workflow invocation (KYB, settlement, remittance, fraud)
- Redis-backed rate limiting via atomic INCR (in-memory fallback for single-instance)
- OpenSearch batch indexer for audit logs, transactions, KYB applications
- Readiness/liveness/startup health probes for Kubernetes (/api/health/live, /ready, /startup)

LOW priority:
- Response compression middleware (gzip, threshold: 1KB)
- ETag support for conditional responses
- Middleware pipeline documentation (docs/middleware-pipeline.md)
- Input sanitizer bypass for trusted routes (BIS, compliance, admin skip SQL detection)
- Fluvio/Lakehouse streaming pipeline with 7 materialized views

TypeScript: 0 errors

… graceful degradation, Docker consolidation

1. Database Integration:
   - Rewrote redisClient.ts with real ioredis (lazy connect, auto-reconnect, pipeline ops)
   - In-memory fallback maintained for when Redis is unavailable
   - All cache operations now try Redis first, fall back to memory

2. Inter-service HTTP wiring:
   - serviceFetch.ts: exponential backoff retries (configurable attempts, delay, jitter)
   - JWT token forwarding on inter-service calls
   - Internal service key propagation (X-Service-Key header)
   - Retry on 502/503/504/408/429 with backoff

3. Security hardening:
   - New jwtAuth.ts: centralized JWT sign/verify, inter-service token generation
   - requireAuth + requireRole Express middleware
   - Removed all hardcoded placeholder credentials from Go services
   - All Go services now use envOrDefault() for secrets
   - Docker Compose uses env vars for DB passwords (POSTGRES_USER, POSTGRES_PASSWORD)
   - Added INTERNAL_SERVICE_KEY for service-to-service auth

4. Integration tests:
   - 7 test suites covering Redis, circuit breaker, degradation, JWT, serviceFetch, gRPC, shutdown
   - Tests validate both module exports and logical behavior

5. Graceful shutdown:
   - gracefulShutdown.ts: SIGTERM/SIGINT/uncaughtException handlers
   - Priority-ordered shutdown hooks with per-hook timeout
   - 15s total shutdown timeout with forced exit fallback

6. Health probes:
   - /api/health/live — process alive check
   - /api/health/ready — dependency health (Postgres + Redis)
   - /api/health/startup — boot completion

7. Graceful degradation:
   - 4-level degradation (full/degraded/minimal/offline)
   - Dependency health tracking with automatic recovery
   - Capability matrix per degradation level
   - withDegradation() wrapper for service calls with fallback

8. gRPC gateway:
   - Proto definitions for Settlement, Fraud, PBAC, Wallet services
   - grpcGateway.ts: HTTP/JSON ↔ gRPC translation with REST fallback
   - Typed client wrappers (settlementClient, fraudClient, pbacClient)

9. Docker consolidation (31 → 15 containers, 52% reduction):
   - 8 Go middleware → 1 unified binary (go-middleware)
   - 4 Rust core → 1 binary (rust-core)
   - 3 Rust streaming → 1 binary (rust-streaming)
   - 3 Python services → 1 process (python-unified)
   - Removed Zookeeper (Kafka KRaft mode)
   - docker-compose.consolidated.yml for optimized deployment

…mail/SMS, LLM copilot, AR tourism, DID resolver, Neo4j, map services, infrastructure clients

CRITICAL:
- Payment rails: M-Pesa (Daraja API), Flutterwave, Wise + unified interface
- Email/SMS: SendGrid + Twilio + Africa's Talking with auto-provider selection
- AR Tourism: WebXR-based experience catalog with geospatial anchors (6 experiences)
- AI Co-Pilot: OpenAI/Anthropic integration with domain-specific tourism prompts

HIGH:
- DID Identity: W3C DID Core compliant with Ed25519 keys (did:web, did:key, did:tourismpay)
- Neo4j: Real driver via HTTP API with in-memory fallback, community detection, shortest path
- Map/Location: Mapbox + OpenStreetMap Nominatim + OSRM directions fallback
- TigerBeetle: Real ledger client via Rust service with in-memory accounting fallback
- Keycloak: Real admin API client with token management and Go proxy fallback
- Kafka: REST proxy + Go processor + in-memory event buffer with flush
- Temporal: HTTP API + Go worker + in-memory workflow execution

MOBILE PARITY:
- Flutter: PaymentSwitch, ML Dashboard, AR Tourism, Loyalty screens
- React Native: PaymentSwitch, BIS Investigation, ML Dashboard, AR Tourism screens

All providers gracefully degrade when API keys are not configured.
TypeScript: 0 errors. 26 new files, +4,200 lines.

- Added tRPC route mappings for tourist services (copilot, identity, AR, map)
  in the PBAC ROUTE_RESOURCE_MAP so tourist role can access these endpoints
- Added service_health prefix to tourist role's fallback permissions
- Fixed copilot.chat fallback chain: when no LLM API keys configured,
  properly return the rule-based response instead of throwing
- Wrapped invokeLLM in try/catch to gracefully handle missing API key

Co-Authored-By: Patrick Munis <pmunis@gmail.com>
- client/src/main.tsx: Read csrf_token cookie and send X-CSRF-Token header on all tRPC requests
- server/security/pbacMiddleware.ts: Fix identity router endpoint names (getDid, stats, listCredentials, revokeCredential)

- LRU eviction in Rust Redis service (50K keys / 256MB, 10% batch eviction)
- Background TTL sweep every 10s in Rust service (passive expiry)
- Cache stats endpoint (/api/cache/stats) with hit rate, stampede count, metrics
- Manual invalidation endpoint (/api/cache/invalidate) for admin use

A) EPHEMERAL STATE: Persist _pinLockout, _highValueTokens, inMemoryEvents,
   memAccounts/memTransfers, slaConfig to Redis with in-memory fallback

B) MISPLACED FILES: Remove .gitkeep, update .gitignore for session artifacts

C) HARDCODED METRICS: Compute successRate/growth from DB queries in analytics,
   compute uptime/errorRate from real server stats in technicalOnboarding

D) MISSING BUILD FILES:
   - Generate go.sum for all 9 Go modules (real go mod tidy)
   - Generate Cargo.lock for 4 Rust services (real cargo generate-lockfile)
   - Add metro.config.js, babel.config.js for React Native
   - Add analysis_options.yaml for Flutter
   - Include package-lock.json for reproducible builds

E) WEAK ERROR HANDLING: Replace critical .catch(() => {}) with logged fallbacks
   in wallet, biometric, kybDocuments, kafkaProducer, PBAC middleware

F) SHALLOW HEALTH ENDPOINTS: Add real dependency checks (Kafka, Redis, model
   dir, DuckDB, data dir) to Go unified, Kafka processor, Rust redis-cache,
   Python lakehouse analytics, ML inference server

… set

Previously the server crashed on startup because Stripe SDK throws when
instantiated with an empty string. Now exports null when no key is configured,
and all callers (webhook, stripeConnect, wallet, touristPortal, bis) guard
with null checks that throw descriptive TRPC errors at call time instead.

Superseded by react-native-mobile/ which has proper architecture
(45 files with screens/services/hooks/i18n/theme/navigation vs 20 minimal files).
Example: wallet screen is 158 lines vs 8 lines in the removed version.

…oute mappings

- wallet.ts: Fix Date.now() → epochSec() for integer columns (walletBalances,
  walletTransactions, finance_requests); fix epochSec() → Date.now() for bigint
  columns (scheduledPayments, walletRecurringPayments)
- wallet.ts: Fix spendingAnalytics SQL to use to_timestamp(col) not
  to_timestamp(col/1000) for integer columns already storing epoch seconds
- wallet.ts: Fix balanceSummary 7-day range to use epoch seconds not milliseconds
- pbacMiddleware.ts: Add 45+ tRPC route PBAC mappings for wallet, loyalty,
  notifications, merchant, sustainability, embedded finance, AR, biometric,
  QR payment, exchange rates, search endpoints
- pbacMiddleware.ts: Expand merchant role fallback to include wallet/payment
  resource access
- stripeWebhook.ts: Fix updatedAt to use epoch seconds for walletBalances

Co-Authored-By: Patrick Munis <pmunis@gmail.com>
P0 Critical:
- Atomic balance operations: all wallet/QR/mesh/sustainability mutations
  now use UPDATE WHERE balance >= amount (prevents double-spend)
- Replace setTimeout async completion with durable scheduled_jobs pattern
  (survives server restarts)
- Add idempotency keys on wallet.send and wallet.swap mutations

P1 Medium:
- SQL aggregation for merchantRevenue (replace unbounded in-memory sum)
- Atomic slot booking in Tourist Portal (prevents overbooking)
- Restrict fraud alert create/resolve/markFalsePositive to adminProcedure

P2 Improvements:
- Sustainability: add USDC wallet deduction on carbon offset purchase
- Embedded Finance: max 3 active loans check prevents over-leveraging
- Fix missing await on settlement listSettlements query
- Standardize error handling: replace all throw new Error with TRPCError
  across wallet, QR, merchant, mesh, tourist, sustainability routers
