Rev 3 of `docs/superpowers/plans/2026-10-16-region-ha-2a-core.md` answers your round 2 (`CODEX-REVIEW-REGION-HA-2A-2.md`) and platform-1e's ruling rev 2 conditions (recorded on amadan #236):
4
- the move door's capacity failure goes through the H27 refusal, and the create door's placement gate gets the same treatment;
5
- `chooseCreateFirst` runs before any mutation in the create path, the environment binding included;
6
- the metric's AWS region comes from the signed roster;
7
- tests cover `chooseExecutorFirst` writing nothing and taking no lease, the same executor being chosen with capacity, and the move room check only refusing.
