Problem and outcome

The source repository still said the GitOps promoter polled the mutable latest tag, but production now resolves the current source revision through its sha-<commit> tag and immutable digest. This updates the operator contract to match the merged release lane.

Implementation and validation

  • Describe source-SHA selection, immutable provenance validation, promotion serialization, and the production completion criteria.
  • Correct the image-build summary so it points operators to the exact sha-<commit> artifact and production verification.
  • Clarify that verification failures are tracked in the GitOps repository.

Validation:

  • actionlint .github/workflows/docs-mcp.yml
  • git diff --check
  • reviewed as a two-file wording-only change against current main

Merging this PR intentionally publishes a new Docs MCP image for this source revision. The merged GitOps lane will use that release as an end-to-end automation check.

Summary by CodeRabbit

  • Documentation
    • Clarified the release workflow for immutable, SHA-tagged image promotion and production verification.
    • Documented deployment safeguards, including provenance validation and prevention of overlapping verification releases.
    • Updated failure-handling guidance to reference GitOps-managed incident issues for any production verification failure.

📝 Walkthrough

Walkthrough

The release workflow summary and operations documentation now describe immutable image promotion, GitOps-managed production verification, verification blocking, and incident handling.

Changes

GitOps deployment verification

Layer / File(s) Summary
Immutable release promotion flow
.github/workflows/docs-mcp.yml, docs-mcp/OPERATIONS.md
The release process now promotes the SHA-tagged image by immutable digest, validates image provenance, blocks overlapping verification releases, and completes after verification begins.
Verification failure and incident handling
docs-mcp/OPERATIONS.md
The GitOps verification workflow now handles rollout and public-canary failures. It creates or updates incident issues in the GitOps repository. An incident issue is required for every production verification failure.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 7156a

The documentation changes promotion and incident-handling guidance, but currently leaves ownership ambiguous when scheduled health checks and rollout verification use the same endpoints. That could misroute or delay incident response, so explicit scope and owner clarification or acceptance is needed before merge.

rollout/public-canary verification incidents from scheduled health-check
incidents, explicitly documenting each incident scope and owning repository;
alternatively, define a single shared incident owner and apply it consistently

Document source-SHA image selection, provenance validation, and end-to-end production verification. Update the image publication summary so it no longer claims GitOps consumes the mutable latest tag.
