Summary

Massive platform buildout adding shared infrastructure SDKs, an AI/ML continuous training platform, a KYC/KYB verification system, and 40+ insurance product microservices. This PR spans multiple subsystems:

Infrastructure SDKs (infrastructure/): Shared client libraries in Go, Python, TypeScript, and Rust for all 12 platform components (PostgreSQL, Redis, Kafka, Keycloak, Permify, OpenSearch, Fluvio, Dapr, TigerBeetle, Mojaloop, APISix, OpenAppSec). Includes a middleware layer (Go/Python/TS) enforcing rate limiting → token validation → KYC gates → RBAC → async audit logging on every request.

AI/ML Platform (ai-ml-platform/): Continuous training pipeline with drift detection (KS/PSI tests), model registry (champion/challenger), scheduled retraining, data ingestion from platform services, and a FastAPI inference server. Includes Lakehouse feature store with Delta Lake, schema registry, and data lineage.

KYC/KYB System (kyc-kyb-system/): Document OCR (PaddleOCR), face verification (DeepFace), liveness detection, identity matching engine (Rust), Temporal workflow orchestrator (Go), Fluvio stream processor, and platform middleware integration.

Microservices & Products: 40+ Go/Python/Rust microservices for insurance domains (parametric, peer-to-peer, livestock, crop, health, micro-insurance, climate risk, etc.) with handlers, repositories, and service layers.

Customer Portal (customer-portal-full/): React dashboard with tRPC procedures, role-based sidebar navigation, and pages for all product categories.

Review & Testing Checklist for Human

  • Security: Hardcoded/default credentials — Multiple services use default passwords, mock auth tokens, and in-memory stores. Search for password, secret, mock, demo across the diff. None of these should reach production without real credential injection.
  • Placeholder logic masquerading as real implementations — Many KYC activities return hardcoded results (e.g., "cac_verified": true, "risk_score": 0.15). The Rust SDK stubs log actions but don't connect to services. Verify which modules are genuinely functional vs. scaffolded.
  • Middleware fail-open behavior — The middleware catches exceptions on Permify/Redis checks and falls through (except Exception: pass). Decide whether fail-open is acceptable per component or if fail-closed is required for KYC/RBAC enforcement.
  • AI/ML models use synthetic data — Training loops generate random data or use toy datasets. Verify the continuous training pipeline works with real platform data before relying on model outputs.
  • No automated test suites — This PR adds ~8,700+ lines across 66+ new files with no unit or integration tests. Consider requiring test coverage for critical paths (middleware enforcement, KYC verification, financial transfers).

Recommended test plan:

  1. Start a Go microservice and verify the middleware chain (rate limit → auth → KYC gate → RBAC → audit log) by sending requests with/without valid tokens
  2. Start the AI/ML inference server (ai-ml-platform/) and hit prediction endpoints to confirm models load
  3. Start the KYC stream processor and publish test events via the /api/v1/stream/publish endpoint
  4. Run go vet ./... in infrastructure/go-sdk/, cargo check in infrastructure/rust-sdk/, tsc --noEmit in infrastructure/ts-sdk/ to confirm compile checks pass
  5. Start the customer portal and verify sidebar renders correctly per role

Notes

  • This PR is very large and combines multiple subsystems. Consider splitting into separate PRs per subsystem for easier review in future iterations.
  • The Rust identity-matching-engine requires Cargo build; its target/ directory is gitignored.
  • Compile checks pass for all 4 SDKs (Go vet, Python py_compile, TypeScript tsc, Rust cargo check) but Rust has unused-variable warnings in stub implementations.

Extract the entire archive, analyze and search for orphan, partially and generic scaffolded features across the platform - fully implement them end to end -generic CRUD-only patterns , modules with no domain logic, disconnected features, and incomplete implementations.

E2E Test Results — Infrastructure SDKs

Session: https://app.devin.ai/sessions/0475192a778b45cea30202f85ad52b63

Summary

Tested all 4 SDK languages for compile correctness, import/initialization, middleware consistency, and graceful degradation. 10/12 tests passed, 2 findings noted.

Test Results Table
# Test Result
1 Go SDK — go vet ./... PASSED
2 Go SDK — Platform init (12 components) PASSED
3 Go SDK — Middleware rate limit FINDING
4 Python SDK — py_compile (15 files) PASSED
5 Python SDK — Middleware import & defaults PASSED
6 Python SDK — Platform class import PASSED
7 TypeScript SDK — tsc --noEmit PASSED
8 TypeScript SDK — Build (15 JS files) PASSED
9 Rust SDK — cargo check PASSED
10 Rust SDK — Module count (12+1) PASSED
11 Cross-SDK middleware consistency PASSED
12 Go SDK — Graceful degradation FINDING
Finding: Middleware Fail-Open vs Fail-Closed Inconsistency
  • Go middleware fails closed when Redis is unavailable — RateLimit() returns (false, error), all requests get HTTP 429
  • Python/TypeScript middleware fail open — catch Redis exceptions and continue serving

Impact: When deployed without Redis, Go services block all traffic while Python/TS services allow it through.

Fix: Either change Go to if err == nil && !allowed (fail open) or change Python/TS to fail closed.
