P13 (wave 2, order 8). docs/release-runbook.md has three parts: before the
release, the release, and the rollback. The rollback was drilled first, in a
sandbox with local bare repos as the remotes: a release 6.2.0 -> 6.2.1, then
path A (git revert, catalog ref back to v6.2.0) and path B (a forward patch
6.2.2 that carries the revert), with the catalog's check-versions green after
each. Nothing reached a real remote; the real catalog was byte-identical
before and after.
Measured: release-plugin.mjs refuses a ref backwards while plugin.json still
says the newer version, and accepts it once the release commit is reverted.
scripts/release-check.mjs decides before a release: clean tree, npm test
green at HEAD, review verdict not BLOCK (K7) and covering HEAD, and a door
type per delivery (### Doors in the CHANGELOG section). 0 ready, 1 not
ready, 2 could not run (never green). A ready run prints the K2 command that
logs the operator's yes.
tests/lib/release-prose-pins.test.mjs holds every command in the rollback
part to the commands the drill ran (tests/fixtures/release-drill/).
