Task D — Google-style docstrings (Args/Returns) on every public function,
method, and class across all 158 Python files in the backend. Zero ruff D
violations (pydocstyle Google convention).
Task E — Explanatory one-line comment before every code line (~11600 new
comments). ruff check passes clean after isort re-sort.
1. New 'disputed' state — one lead approved, the other rejected:
- Both approved → validated (unchanged)
- Both rejected → rejected (unchanged)
- One approves + one rejects → disputed (new)
- DB: ALTER TYPE teststate ADD VALUE 'disputed'
- Notification sent to the approving lead explaining the conflict
with the rejection notes
2. Disputed UI in TestDetailHeader:
- Amber banner showing conflict + rejection reason from notes
- 'Change Vote to Rejected' button for the lead who approved
- Validation indicators shown for disputed state too
3. Fix timestamps on reopen (rejected → draft):
- Keep red_started_at, blue_started_at etc. as historical record
- Only clear paused_at defensively
- Timestamps naturally update when test is re-executed
4. disputed badge (amber) added to all badge color maps
