## ✅ QA Verification: PASSED ### Summary All requirements verified and implementation confirmed working correctly. ### Test Results - ✅ All 29 tests pass (0.55s) - ✅ Linting passes (ruff check) - ✅ Manual verification successful - ✅ Lifespan manager properly initializes and closes database - ✅ /health endpoint returns {"status":"healthy"} (200) - ✅ /api/status endpoint returns version, service, timestamp (200) - ✅ CORS configured correctly (allows all origins with credentials) - ✅ Exception handlers work (404 for unknown endpoints) - ✅ Logging configured to stdout with timestamps ### Manual Testing \`\`\`bash $ curl localhost:8765/health {"status":"healthy"} $ curl localhost:8765/api/status {"status":"healthy","version":"0.1.0","service":"cdev","timestamp":"2025-12-24T07:29:00.662148Z"} \`\`\` ### Known Limitation ⚠️ Application requires \`/data/\` directory to exist before startup. Created with: \`\`\`bash sudo mkdir -p /data && sudo chown gateway:gateway /data \`\`\` ### Files Verified - app/main.py:1-130 - FastAPI application with all required features - tests/test_api_health.py:1-133 - Comprehensive test coverage ### Verdict **✅ APPROVED** - Ready for production deployment Full QA report: /tmp/qa-CDEV-3.md

## Implementation Complete ### Changes Made: 1. **Created `app/main.py`** with: - Lifespan manager for startup/shutdown (initializes and closes database) - `/health` endpoint returning `{"status": "healthy"}` - `/api/status` endpoint returning version, service name, and timestamp - CORS middleware configured for all origins with credentials - Logging to stdout with timestamps - Global exception handlers for unhandled errors (500) and ValueError (400) 2. **Created `tests/test_api_health.py`** with: - Tests for /health endpoint (status code, JSON response, content type) - Tests for /api/status endpoint (status, version, service name, timestamp) - Tests for CORS headers (origin handling, credentials) - Tests for 404 handling ### Verification: - All 29 tests pass (`make test`) - Lint passes (`make lint`) - Manual verification with curl: - `curl localhost:8765/health` → `{"status":"healthy"}` - `curl localhost:8765/api/status` → `{"status":"healthy","version":"0.1.0","service":"cdev","timestamp":"..."}` ### Files: - `app/main.py:1-130` - Main FastAPI application - `tests/test_api_health.py:1-133` - Endpoint tests
