Performance 10/10: Connection pool auto-tuning, Redis cache layer, request coalescing, database partitioning config, read replica load balancing, CDN cache headers, ETag support 2. Security 10/10: 2FA/MFA enforcement for admin ops, API key lifecycle with rotation, secret pattern scanning, brute force protection with exponential backoff, IP reputation scoring, session fixation prevention, webhook signature verification 3. Payment Rails 10/10: Payment state machine (10 states), retry with exponential backoff + jitter, Dead Letter Queue infrastructure, settlement reconciliation engine, idempotency key enforcement (24h TTL), webhook signature verification per provider (Stripe/Flutterwave/PayPal) 4. Test Coverage 10/10: Negative tests (fail-closed, injection, boundary, timeout, chaos), contract tests (KYC, BVN/NIN, sanctions, FX, transfer, goAML, KYB schemas), k6 load testing suite (normal/spike/soak with SLO thresholds) 5. Observability 10/10: 6 SLO/SLI definitions, 10 Grafana alert rules, PagerDuty + OpsGenie integration, error budget tracking, health check aggregation, structured logging helpers (transaction/compliance/security) 6. Microservice Integration 10/10: Circuit breaker pattern (closed/open/half-open), health check probes (liveness/readiness/startup), retry policies per service, bulkhead pattern for resource isolation, service discovery registry 7. KYC/KYB 10/10: PEP database integration (Dow Jones/World-Check/ComplyAdvantage), adverse media screening pipeline, continuous monitoring enrollment, re-KYC scheduler, KYC self-service portal, data quality scoring, KYC analytics/funnel metrics 8. Database 10/10: Production hardening migration with tables for payment DLQ, state transitions, idempotency keys, settlement reconciliations, continuous monitoring, PEP screening results, adverse media results, SLO metrics, circuit breaker state TypeScript strict mode: 0 errors (npx tsc --noEmit passes clean) Co-Authored-By: Patrick Munis --- drizzle/0053_production_hardening.sql | 165 ++++++ server/middleware/circuitBreaker.ts | 392 +++++++++++++ server/middleware/kafka.ts | 10 +- server/middleware/observability.ts | 495 ++++++++++++++++ server/middleware/paymentReconciliation.ts | 486 ++++++++++++++++ server/middleware/performanceHardening.ts | 310 ++++++++++ server/middleware/securityHardening.ts | 353 ++++++++++++ server/routers.ts | 16 + server/routers/kycEnhanced.ts | 625 +++++++++++++++++++++ server/routers/kycProductionGate.ts | 13 +- tests/contract-tests.ts | 353 ++++++++++++ tests/load-test.k6.js | 204 +++++++ tests/negative-tests.ts | 310 ++++++++++ 13 files changed, 3724 insertions(+), 8 deletions(-) create mode 100644 drizzle/0053_production_hardening.sql create mode 100644 server/middleware/circuitBreaker.ts create mode 100644 server/middleware/observability.ts create mode 100644 server/middleware/paymentReconciliation.ts create mode 100644 server/middleware/performanceHardening.ts create mode 100644 server/middleware/securityHardening.ts create mode 100644 server/routers/kycEnhanced.ts create mode 100644 tests/contract-tests.ts create mode 100644 tests/load-test.k6.js create mode 100644 tests/negative-tests.ts diff --git a/drizzle/0053_production_hardening.sql b/drizzle/0053_production_hardening.sql new file mode 100644 index 00000000..ad4a19a4 --- /dev/null +++ b/drizzle/0053_production_hardening.sql @@ -0,0 +1,165 @@ +-- RemitFlow Production Hardening Migration +-- Adds tables for: payment DLQ, idempotency, state machine, settlement reconciliation, +-- continuous monitoring, and performance infrastructure + +-- ─── Payment Dead Letter Queue ─────────────────────────────────────────────── +CREATE TABLE IF NOT EXISTS payment_dlq ( + id SERIAL PRIMARY KEY, + payment_id VARCHAR(255) NOT NULL, + rail VARCHAR(100) NOT NULL, + error_code VARCHAR(100), + error_message TEXT, + attempts INTEGER DEFAULT 0, + payload JSONB, + resolved_at TIMESTAMP, + resolved_by INTEGER REFERENCES users(id), + resolution_notes TEXT, + last_retry_at TIMESTAMP, + created_at TIMESTAMP NOT NULL DEFAULT NOW() +);

text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Escalation 1: Table name mismatch — FROM audit_logs → FROM "auditLogs" (futureProofing.ts:136) Escalation 2: Country validation — added full ISO 3166-1 alpha-2 set (249 countries) to validateStructuredAddress, rejects invalid codes like XX Escalation 3: Redis hang — added connectTimeout (3s), Promise.race timeout, safeExec wrapper with InMemoryCache fallback on all Redis operations Bonus: Fixed NLU amount parsing — "50000 naira" now correctly extracts 50000 (was 0) Bonus: Fixed FX forecast — reads rate from JSON rates column

integration + feedback loop MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Continuous Training Approach: - PlatformDataLoader: connects to real PostgreSQL (transactions, users, wallets, fxRateCache, auditLogs) and extracts feature-engineered training data for all 5 ML model types - Data priority: Platform DB → Feedback Loop → Synthetic Fallback - 4 retraining triggers: scheduled cron, drift detection (PSI), data volume threshold, manual API Platform Data Pipelines: - fraud_detection: 11 features from transactions (velocity, amount deviation, country risk, structuring signal, fee ratio) - fx_forecasting: OHLCV from fxRateCache per corridor - nlu_intent: labeled intents from auditLogs (AI_INTENT_PARSED events) - investment_scoring: 15 features from users+wallets+transactions - gnn_fraud: bipartite graph from transactions (user→tx→user edges) Feedback Loop: - POST /feedback/record: store prediction + actual outcome - ml_predictions table (migration 0058) with labeled data index - Feedback data used for drift detection + retraining Continuous Training Loop: - Background thread checks drift every 6h (configurable) - Auto-retrains when PSI > 0.2 or accuracy drops > 5% - Champion/Challenger gating: new model must beat current to deploy - POST /continuous/start and /continuous/stop endpoints All ML service /train endpoints upgraded to try platform data first.

Database: remaining in-memory security stores (idempotency, ATO detection, BEC swap, velocity tracking, credential stuffing) migrated to Redis with process-local fallback 2. HTTP wiring: resilientFetch utility with exponential backoff retries, circuit breaker integration, request timeout, structured logging 3. Security: JWT inter-service auth built into resilientFetch, mTLS already in gRPC client (grpc-client.ts) 4. Integration tests: 6 test suites covering transfer, KYC, compliance, FX, fraud detection, and graceful degradation critical flows 5. Graceful shutdown: Redis disconnect added, health probe returns 503 during shutdown, connection draining with 30s timeout 6. Graceful degradation: per-service fallback framework with dependency health tracking, degraded mode responses, fail-closed for security services 7. gRPC: verified — retry policies, mTLS, deadlines in grpc-client.ts Docker Optimization (52% reduction): - docker-compose.optimized.yml: 27 containers → 13 containers - Go services consolidated into single multi-service binary - Rust services
