Refs MOT-4614

Consolidates worker publication into one immutable deployment path that accepts an exact target version and a next or latest channel selected by Release Control.

Technical details

  • Reduces deployment execution to prepare, publish, and verify.
  • Replaces candidate, stable, image-alias, and finalize entrypoints with deploy-publish.
  • Publishes immutable Registry versions before explicit channel CAS.
  • Advances next before latest only when required and never regresses next.
  • Preserves historical rc ordering for existing pointers while rejecting rc as a new deployment target.
  • Uses batch and target identity in OIDC authorization, results, and artifact recovery.
  • Pins the byte-identical Release Control deployment result schema.

Summary by CodeRabbit

  • New Features

    • Introduced a streamlined deployment flow with prepare, publish, and verify phases.
    • Deployments now use one exact target version and explicitly select the next or latest channel.
    • Publishing includes immutable Registry versions, channel updates, and OCI image aliases.
    • Added safeguards to prevent channel regressions and reject unsupported legacy release-candidate versions.
  • Documentation

    • Updated deployment guides and workflow labels to reflect the new terminology and process.
  • Bug Fixes

    • Improved retry safety, version verification, and deployment result reporting.

📝 Walkthrough

Walkthrough

The deployment executor now uses one exact target version and channel. Six workflows are consolidated into prepare, publish, and verify. Registry publication separates immutable version creation from explicit channel CAS operations, with target-based identities and artifacts.

Changes

Deployment executor

Layer / File(s) Summary
Deployment contract and target validation
.github/contracts/*, .github/scripts/_lib.py, .github/scripts/deployment_control_contract.py, .github/scripts/deployment_train.py, .github/scripts/build_publish_payload.py, .github/scripts/tests/*
Contracts now require target_version, channel, deployment_batch_id, and deployment_target_id. Target versions reject numbered RC suffixes. Payloads no longer contain implicit registry tags.
Immutable version and channel publication
.github/scripts/registry_publication.py, .github/workflows/_deploy-registry.yml, .github/scripts/tests/test_registry_publication.py
Registry publication creates or proves immutable versions, assigns only next or latest, and preserves the next floor with CAS checks.
Prepare, publish, and verify workflows
.github/workflows/deploy-prepare.yml, .github/workflows/deploy-publish.yml, .github/workflows/deploy-verify.yml, .github/scripts/tests/test_deployment_workflows.py, .github/scripts/tests/test_deployment_effects.py
Workflows use target-based identities and artifacts. Publish handles GitHub releases, Registry channels, OCI images, image aliases, effect probing, and result reporting. Verify checks the target version across public surfaces.
Deployment topology and documentation
.github/DEPLOYMENT_CUTOVER.md, README.md, docs/architecture/*, docs/sops/*, .github/workflows/*-e2e.yml, .github/scripts/registry_worker_smoke.py
Documentation and workflow labels describe the consolidated deployment phases, target selection, channel semantics, and target-based result identity.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 46c4d

The refactor consolidates deployment publication, but the current path can still move channels outside the guarded assignment flow, while Registry and OCI updates may diverge if publication is interrupted. Merge should wait for these safeguards or explicit owner acceptance.

Poem

I’m a rabbit guarding the target trail
One version hops where six had failed
Channels move with careful paws
Immutable tags obey the laws
Next stays high, and latest stays bright
The deployment burrows end in flight

166-167: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Reject tag in immutable publish payloads.

Line 166 still permits a tag field. publish_version sends that payload to /publish, and prove_publication treats the field as a channel pointer. A caller can therefore move a channel without assign_channel and without its compare-and-swap precondition.

Remove tag from the accepted payload contract. Reject it when present. Require all channel movement through assign_channel.

Proposed fix
-        "tag",
         "type",
@@
     if "tag" in payload:
-        _required_string(payload["tag"], "payload.tag")
+        raise RegistryPublicationError(
+            "publish payload must not assign a deployment channel"
+        )
