Optimize detection service and add comprehensive analysis endpoint #369
Conversation
- Optimize `detect_all` to use a single Hugging Face API call for multiple categories, reducing latency and cost. - Add `POST /api/analyze-issue` endpoint for comprehensive issue analysis (visual + text urgency). - Increase cache sizes in `backend/cache.py` to improve performance. - Cleanup deprecated `backend/hf_service.py`. - Fix return type consistency in `get_recent_issues`.

📝 WalkthroughWalkthroughThe PR relaxes validation and error handling during application startup. It makes CORS configuration more permissive when FRONTEND_URL is missing or invalid by logging warnings instead of raising errors, removes a dependency from render requirements, and changes startup validation to proceed with warnings rather than blocking on missing environment variables.

Pull request overview
This PR consolidates multiple Hugging Face CLIP detections into a single optimized call, wires that into the unified detection flow, and adds a new “analyze issue” API endpoint that combines visual detection with text urgency analysis.
Changes:
- Add
detect_all_clip(single CLIP call across multiple categories) and port missing HF detectors intohf_api_service. - Update unified detection to use
hf_api_service(anddetect_all_clip) for the Hugging Face backend, and remove the deprecatedhf_service.py. - Add
/api/analyze-issueendpoint to run visual + text analysis in parallel; adjust recent issues response to consistently returnJSONResponse; increase cache sizes.

detect_all_clip builds unique_labels from a set, which makes the candidate label order non-deterministic across runs. This can reduce upstream caching effectiveness (payload changes) and makes results/debugging harder to reproduce. Consider preserving a deterministic order (e.g., stable first-seen order or sorting) when constructing the candidate label list.

detect_all_clip reimplements the CLIP result filtering logic (including the 0.4 threshold) instead of reusing the existing _detect_clip_generic/shared filtering helper. This duplicates behavior in multiple places and risks future drift if the threshold/format changes. Consider factoring the filtering into a shared helper used by both the per-category detectors and detect_all_clip.

analyze_urgency_text is already imported at module scope, but the endpoint re-imports it inside the function. This is redundant and makes it less clear which import is actually used; consider removing the inner import and using the existing module-level import.

detect_all_clip is new behavior that changes how multiple categories are detected (single HF call + category partitioning), but there are no unit tests validating that it correctly maps HF results into the per-category outputs. There are already async tests for hf_api_service in tests/test_hf_api.py; please add coverage for detect_all_clip (including thresholds and multiple-category matches).

P1: Softmax score dilution: combining ~33 labels in a single CLIP call with a 0.4 threshold will miss detections that individual calls (with ~7 labels each) would catch.
The HF zero-shot classification API uses softmax normalization by default, spreading probability across all candidate labels. With 33 labels instead of ~7, individual label scores are much lower, so the 0.4 threshold that works for individual detection functions becomes too aggressive here. Consider either lowering the threshold or passing `multi_label=True` in the API parameters so each label gets an independent sigmoid score.</violation>

Security: Wildcard CORS origin with allow_credentials=True is dangerous in production.
When FRONTEND_URL is missing or invalid in production, frontend_url falls back to "*". Combined with allow_credentials=True on Line 156, Starlette's CORSMiddleware will reflect any requesting Origin header back as Access-Control-Allow-Origin while also sending Access-Control-Allow-Credentials: true. This means any website can make fully credentialed (cookie/auth-bearing) cross-origin requests to your API — a textbook CSRF/credential-theft vector.
A safer fallback would be to either refuse to start or use a known safe origin. If you truly need a permissive deployment escape hatch, at minimum disable credentials when using a wildcard:

<comment>When required environment variables are missing, the function now falls through to unconditionally print `"✅ Environment validation passed"`, contradicting the warning printed just above. The validation did *not* pass — it was merely downgraded to non-fatal. Add an `else` or an early return-after-warning so the success message is only printed when all required variables are actually present.</comment>
