 Docker Verify builds each service locally (`load: true`, no push) and runs pinned Trivy v0.74.0 against that local image. Docker Publish pushes digest-only candidates: it does not assign normal `sha-*` or `v*` release tags while individual service gates are running.
 
-Each service must pass HIGH/CRITICAL Trivy scanning, then be signed and receive SPDX/SLSA attestations for the same candidate digest. The `promote` job runs only after all nine matrix builds succeed; it validates all nine reports, source commit, digest subjects, signer identity, and verified DSSE predicates before inspecting or writing any tags.
+Each service must pass HIGH/CRITICAL Trivy scanning, then be signed and receive SPDX/SLSA attestations for the same candidate digest. The `promote` job runs only after all nine matrix builds succeed; it validates all nine reports, source commit, digest subjects, signer identity, and verified DSSE predicates before inspecting or writing any tags. A changed backend image requires a new service release version in both `services/pom.xml` and its owner POM; an existing version tag may only be reused for the identical digest. Keep contract fixtures aligned with the intended release versions instead of weakening the immutable-tag guard.
 
 Use `release-manifest` artifact from successful Docker Publish run as canonical deployment input. It contains complete nine-service `release-manifest.txt`, `release-set.json`, and per-service evidence. Local `scripts/runbooks/promote-release.sh EVIDENCE_DIR SOURCE_SHA ghcr.io/davidhlp/ulticode` supports read-only dry-run only; `--execute` is restricted to Docker Publish on `main`. The workflow uses repository-wide `ulticode-release-tag-writer` concurrency with cancellation disabled. If promotion fails after candidate builds succeed, rerun only the failed `promote` job in that same Actions run, while its nine candidate artifacts remain within their retention period; do not rerun successful `build-and-push` jobs, since a rebuild may produce a different digest and collide with immutable tags. The workflow is push-only and has no `workflow_dispatch`. Do not promote tags through local commands or other writers. This serializes repository-controlled writers, not external registry actors, and GHCR offers no compare-and-swap guarantee here. Existing manifest conflicts fail before registry inspection/writes; all planned tags are read back after promotion, including tags that already existed, before complete manifests are written. Matching existing tags are idempotent; a different digest is a hard failure. A mid-promotion failure may leave already verified tags in place, but emits no complete manifest. Never retarget or delete old tags/digests; retain previous successful release artifact for rollback.
