- Every milestone branch is cut from the latest default branch: the next
milestone builds on the merged previous one, and a redo after a closed PR
drops the rejected work. Uncommitted work comes along.
- While the item's PR is open, start_milestone is refused, with the PR's
state read from Gitea at that moment, not the last watch round.
- finish_milestone(final): earlier PRs say "Part of #N", the last "Closes
#N"; unsaid, it's final, as before.
- close_item with the item's PR still open waits for the merge (L2: a
closed item leaves nothing open).
- The driver's instructions cover ARCHITECTURE.md and build plans under
docs/plans/ (D2); the harness never parses a plan.
- Parking stashes uncommitted work and pushes it to <item>-parked, put back
on resume, instead of committing it onto the item's branch. The walk
found a half-done review fix parked onto a PR that had merged meanwhile,
where it was lost. Architecture D4's parking line says so.
Tests: unit tests for fresh milestone branches, the merge wait (including
a merge not yet watched), redo after a closed PR, Part of/Closes, close
waiting on an open PR, and the parked-fix regression; the walk's new
milestones_start_fresh property (fork-from-current fails 9 seeds); an e2e
two-milestone feature.
