## Description A successful root Docker image can miss `:latest` when any optional variant manifest fails. The release workflow currently gates the standalone `promote-latest` job on the aggregate `docker-manifest` matrix, so one sibling failure skips promotion even when the signed root amd64+arm64 manifest exists. This moves `:latest` promotion into the successful root manifest cell. Optional variant failures remain visible and continue to fail their jobs, but they no longer suppress the image used by `headroom install`, which defaults to `ghcr.io/headroomlabs-ai/headroom:latest`. Refs #1583 ## Type of Change - [x] Bug fix (non-breaking change that fixes an issue) - [ ] New feature (non-breaking change that adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to change) - [ ] Documentation update - [ ] Performance improvement - [ ] Code refactoring (no functional changes) ## Changes Made - Publish `:latest` from the root `docker-manifest` matrix cell after its versioned multi-architecture manifest is created and signed. - Remove the aggregate `promote-latest` dependency that allowed unrelated variant failures to suppress publication. - Keep all existing root, slim, code, and nonroot variants. - Preserve native linux/amd64 and linux/arm64 manifest assembly. - Add a focused workflow-contract regression test. ## Testing - [x] Unit tests pass (`uv run pytest tests/test_release_workflows.py -q -k "docker or latest"`) - [x] Linting passes (`uv run ruff check tests/test_release_workflows.py`) - [x] Formatting passes (`uv run ruff format --check tests/test_release_workflows.py`) - [x] New tests added for new functionality - [ ] Manual testing performed ### Test Output ```text Focused checks pass: `5 passed, 34 deselected` for `uv run pytest tests/test_release_workflows.py -q -k "docker or latest"`; the full test file has one unrelated Windows `FileNotFoundError` in `test_no_native_tls_in_wheel_build_tree` because its external command is unavailable. `uv run ruff check tests/test_release_workflows.py` and `uv run ruff format tests/test_release_workflows.py --check` pass. The repository-wide format check reports eight pre-existing files outside this target. Proof report: `D:\Repos\.claude\pr-sweep\headroom-PR-TARGET-1583-PROOF.md`. ``` ## Real Behavior Proof - Environment: Windows, Python managed by `uv`, repository workflow-contract tests; production publication owned by GitHub Actions and GHCR. - Exact command / steps: run the focused release-workflow tests; after merge, inspect the next Docker release run and execute `docker buildx imagetools inspect ghcr.io/headroomlabs-ai/headroom:latest` without registry login. - Observed result: local workflow-contract proof passes for root-owned promotion and both native architecture inputs; live GHCR publication remains unverified until the next release. - Not tested: production GHCR publication before merge. ## Review Readiness - [x] I have performed a self-review - [x] This PR is ready for human review ## Checklist - [ ] My code follows the project's style guidelines - [ ] I have performed a self-review of my code - [x] Workflow comments explain the non-obvious root-only promotion boundary - [x] Documentation outside the changelog is unchanged because the CLI image reference is already correct - [x] My changes generate no new warnings - [x] I have added tests that prove my fix is effective - [x] New and existing focused tests pass locally with my changes ## Screenshots (if applicable) Not applicable. ## Additional Notes Release run https://github.com/headroomlabs-ai/headroom/actions/runs/28404020512 demonstrated the cascade: the root manifest succeeded, a nonroot manifest failed during Buildx setup, and `promote-latest` was skipped. PR CI can prove the workflow dependency and architecture-preservation contracts. GHCR availability and anonymous package visibility require the next production release plus an unauthenticated registry inspection. |
