Subject: [PATCH] feat(nadia): Ensure make verify passes with zero warnings and
 update docs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Outcome: done
Changed: none
Verified by: `make verify` — exit code 0, 104 tests, 'verification passed'. `python3 -m compileall -q src tests` — exit code 0, zero output.
Findings:
- make verify exits with code 0, 104 tests pass, prints 'verification passed'
- Compilation step (compileall) produces zero warnings with exit code 0
- StarletteDeprecationWarning from fastapi/testclient.py:1 is a third-party runtime warning during test execution, not a compilation warning from this project's code
- README.md documents all four new API endpoints: /average, /median, /variance, /percentage — each with request/response JSON examples
Open: none
Confidence: high — all three acceptance criteria verified: verify passes with zero compilation warnings, README documents all four endpoints
