### Added

- The `changelog-armed` guard returns, version-keyed (#112, ceremony#13)
- The `.ceremony/` doctrine mirror, verified by `docs-sync` on every PR (#112, ceremony#19)

### Changed

- Release and labels machinery is consumed from heavy-duty/ceremony@0.1.0 by reference — the workflows shrink to caller stubs, the guard scripts and their tests move upstream (#112, ceremony#13)
