Milestone A PR skill

1. Read MILESTONE_A.md + BUILD_CHECKPOINTS.md.
2. Follow PR_PROTOCOL.md exactly.
3. One architectural purpose per PR; use milestone-a/<name> branches.
4. Required pattern:

inventory → characterize → shared impl → parity → cutover
→ delete duplicate → regression → docs → SESSION_LOG

5. After Open-FDD PyPI changes: separate playground PR + GHCR refresh.
6. Fill evidence into PR body; update checkpoints when phase status changes.
7. Stop only on exit criteria or documented external blocker.
