- Started broad codebase improvement pass.
- Created working notes for persistent audit context.
- Mapped repo structure and identified large service/route/worker hotspots.
- Identified CI path drift, stale Gemini model IDs, header normalization risk, and inconsistent upstream response-header filtering.
- Patched CI Worker test path, Gemini registry/docs, proxy header handling, upstream response-header filtering, and PWA static-file serving.
- Verified with Worker tests, targeted unittest suite, full unittest discovery, compileall, and static secret scan.
