Rehearse the rollback before any irreversible action: name the specific restore path and demonstrate it works — never proceed on the strength of 'a backup exists'. Use before deletes, drops, force-pushes, migrations, or any action semver-gate classifies as MAJOR.

PORTABILITY: pure procedural discipline — no hooks, no subagent-spawning tool, no Workflow tool, no harness-specific primitive. The rehearsal is ordinary commands (restore into a scratch path, diff, dry-run) that any harness with a shell can run. Ports anywhere the agent can execute a command and read its output before acting.
