Roll the published head back to a retained prior revision (expected-head CAS)
Same fenced CAS as publish, restricted to a revision that was a prior head of this project and still has a sealed artifact and a READY release service. No rebuild, no model re-run. Immutable revision URLs are untouched; only the head moves.

Body
application/json
The published head the caller observed. The CAS wins only if it still matches (revisionId + generation).

Outcome
Typed operational outcome. ok:false carries a closed code (HEAD_CONFLICT with current, ARTIFACT_NOT_SEALED, SERVICE_NOT_READY, NOT_A_PRIOR_HEAD, SERVING_PUBLISHED_HEAD, STALE_GENERATION with currentGeneration, GUEST_UNAVAILABLE, GUEST_STOP_FAILED); a lost CAS is reported, never retried blindly.
