Returns: `["pr1", "pr2", "pr3"]` ### `POST /analyze` Analyze a PR with SSE streaming. **Request Body:** ```json { "pr_number": 123, "repo_owner": "owner", "repo_name": "repo", "use_fixture": "pr1" // Optional: use fixture for offline testing } ``` **Response:** Server-Sent Events stream Event types: - `finding`: Individual finding discovered - `dialogue`: Character dialogue - `complete`: Analysis complete with full result - `error`: Error occurred ### `POST /analyze/sync` Analyze a PR and return complete result (non-streaming). Same request body as `/analyze`, returns full `EncounterResult` JSON. ## Testing with Fixtures Three PR fixtures are available for offline testing: ### PR1: Security Critical (Blocked) ```bash curl -X POST http://localhost:8000/analyze/sync \ -H "Content-Type: application/json" \ -d '{"pr_number": 1, "repo_owner": "test", "repo_name": "test", "use_fixture": "pr1"}' ``` Expected: 274 damage, BLOCKED verdict, 7 critical security findings ### PR2: Mixed Issues (Changes Required) ```bash curl -X POST http://localhost:8000/analyze/sync \ -H "Content-Type: application/json" \ -d '{"pr_number": 2, "repo_owner": "test", "repo_name": "test", "use_fixture": "pr2"}' ``` Expected: 162 damage, CHANGES REQUIRED verdict, 8 mixed severity findings ### PR3: Clean Code (Approved) ```bash curl -X POST http://localhost:8000/analyze/sync \ -H "Content-Type: application/json" \ -d '{"pr_number": 3, "repo_owner": "test", "repo_name": "test", "use_fixture": "pr3"}' ``` Expected: 44 damage, APPROVED verdict, 3 minor findings ## Project Structure ``` backend/ ├── app/ │ ├── __init__.py │ ├── main.py # FastAPI application │ ├── config.py # Settings & environment │ ├── models.py # Pydantic models (JSON contract) │ ├── logging_config.py # Structured logging │ ├── clients/ │ │ ├── bob_client.py # IBM Bob API client │ │ └── watsonx_client.py # watsonx.ai client (IAM refresh) │ └── services/ │ ├── orchestrator.py # Main analysis pipeline │ ├── classifier.py # Character assignment │ ├── voice_rewriter.py # Granite voice rewriting │ └── fixture_loader.py # Fixture loading ├── requirements.txt ├── .env.example └── README.md ``` ## Key Implementation Details ### IAM Token Refresh watsonx.ai IAM tokens expire after 60 minutes. The `WatsonxClient` automatically refreshes tokens 5 minutes before expiry to prevent mid-request failures. ### Damage System - **Critical** (80-100 dmg): RCE, data loss → `crit_hit` animation - **High** (40-70 dmg): Serious bugs → `hit` animation - **Medium** (15-35 dmg): Code smells → `graze` animation - **Low** (5-10 dmg): Nits → `whisper` animation PR starts at 100 HP: - ≥80 damage: BLOCKED - 50-79 damage: CHANGES REQUIRED - <50 damage: APPROVED ### Structured Logging All Bob/Granite API calls are logged in JSON format with: - Request/response lengths - Elapsed time - Error details - Token usage (when available) Logs are written to stdout for container compatibility. ## Development ### Run Tests ```bash pytest ``` ### Type Checking ```bash mypy app/ ``` ### Code Formatting ```bash black app/ isort app/ ``` ## Troubleshooting ### Import Errors Make sure virtual environment is activated and dependencies are installed: ```bash pip install -r requirements.txt ``` ### API Key Errors Verify `.env` file exists and contains valid API keys: ```bash cat .env ``` ### Token Expiry If you see authentication errors after 60 minutes, the IAM token refresh may have failed. Check logs for `watsonx_token_refreshed` events. ### Fixture Not Found Ensure you're running from the project root directory where `fixtures/` exists: ```bash # Should show fixtures directory ls fixtures/ ``` ## Production Deployment 1. Set `LOG_LEVEL=INFO` in production 2. Use proper CORS origins (not `*`) 3. Enable HTTPS 4. Set up monitoring for token refresh failures 5.
