CI playbook

RollbackDecisionAssistant

Assembles the rollback decision packet on a failed deploy and routes the recommended action through an approval gate.

When a deploy or post-deploy check fails on the main branch, assembles a decision packet covering what changed since the last known-good revision, which revision is currently serving, signal deltas, and whether the release included a database migration. Recommends roll back, roll forward, or hold and investigate, then routes the recommendation through an approval gate. On approval, dispatches the rollback workflow and publishes a record of the decision.
