Daily Work Report (Apr 11, 2026)

Work Summary

Built an Internal Development Suite at /app — a lightweight, isolated SPA to test and debug the image-processing pipeline without impacting production flows. Delivered infrastructure, a developer testing UI, API chaining (Validate → Analyze), visual debugging tools, and backend alignment for predictable debugging behavior.

Show Your Work (References)

• Internal App Infrastructure Setup
  • Created internal_app/ and mounted under /app in main.py.
  • Implemented as a standalone HTML-based SPA (no external framework required).
• Developer-Focused UI (Testing Interface)
  • internal_app/index.html supports dual input modes: local upload and remote image URL.
  • Added wipe_cache toggle (default: True) to enable fresh-test runs.
• Validate → Analyze Workflow Integration
  • Frontend flow: Validate → receive image_id → Analyze using image_id.
  • Ensures accurate chaining of multi-step API calls for realistic testing.
• Visual Debugging Tools
  • Exposes image_id for tracing requests.
  • JSON viewers for validation and analysis responses.
  • Image preview for verifying cropping and MediaPipe face alignment.
• Backend Enhancements Alignment
  • Compatible with image_url fetching, wipe_cache behavior, and updated validation schema.
  • Confirmed API responses are display-ready for the internal UI.
• Container/runtime & verification notes
  • (Preserve: testing and verification steps performed in original entry — validate redirect/required fields, PNG/JPEG checks, compile checks across modified modules.)

Learnings / Outcomes

• Internal tools accelerate debugging and reduce reliance on external clients.
• A minimal HTML SPA is often sufficient for developer testing and lowers complexity.
• Default wipe_cache=True is useful to observe live model changes during tests.
• Visual debugging (image preview + JSON) significantly cuts diagnosis time.

Blockers / Risks

• Remote image inputs present risks: invalid URLs, large payloads, unsupported formats.
• Internal tooling must be isolated or access-restricted to avoid accidental production exposure.
• UI must handle errors gracefully to avoid misleading debug sessions.

Skills Used

Frontend: HTML SPA design; Backend: FastAPI/endpoint chaining and validation; Validation schema design; Debugging: MediaPipe output visualization; DevOps: container/runtime awareness for testing; Automation: test/verification using TestClient and compile checks.

Next Step

1. Add error handling for invalid URLs and large file sizes in the internal UI.
2. Implement basic authentication or access restrictions for /app.
3. Enhance JSON viewer with formatting and collapsible sections.
4. Optionally add request-logging history for debugging sessions.

Outcome

Internal developer testing interface now available at /app, enabling rapid Validate → Analyze testing, improving debugging efficiency, and preparing integration behaviors for production-ready deployment.
