Review finding (low, doc-only): the rollback plan said each stage is one independently-revertable commit, but each stage is actually two commits on its branch (feature + review-round fix, the latter often fixing a real bug), so reverting a single commit would orphan the review-round fix. Reword the unit of rollback to the whole STAGE (branch/PR) and spell out the revert command per merge strategy: squash-merge -> revert the one squash commit; merge-commit -> revert -m 1 the merge; linear history -> revert the full range of the stage's commits.
