Make workflow merge admission accept valid foreach completion and terminate retries when proof is unavailable. - Treat fully terminal live foreach steps as implementation proof for Review Level 0 workflows. - Preserve merge-boundary-unproven as a terminal graph failure and park blocked retries visibly. - Add unit, graph-boundary, and PostgreSQL regression coverage plus operator documentation and a patch changeset.
