Outcome: done
Changed: requirements.txt:1
Verified by: `make verify` — passed, 67 tests, no failures
Findings: requirements.txt no longer lists Flask; now lists fastapi and uvicorn[standard], matching pyproject.toml.
Open: none
Confidence: high - single-file edit, verified, CI uses `pip install -e .` so the change has no effect on CI pipeline
