Fix failing GitHub Actions for the current branch. Use gh, never GitHub MCP for Actions logs. Follow git publish.

1. git branch --show-current. Resolve the upstream tracking branch and confirm it exists. git status -sb is not proof the branch is pushed. Confirm HEAD is not ahead of upstream, or identify the PR head SHA (gh pr view --json headRefOid) and use that SHA when selecting runs.
2. gh pr checks; gh run list --branch "$(git branch --show-current)" --limit 10 (or --commit <headSha>); failed run → gh run view <id> --log-failed; artifacts → gh run download <id>.
3. Parse logs for tests, lint, build, missing deps, env, timeouts. When 2+ jobs failed, spawn one read-only parser per distinct job. Change the owning cause yourself.
4. Re-run the same local commands the workflow uses. Do not add gh run watch to every push. No commit or push unless the user requested that action.
5. Docs: /w-docs if behavior or commands changed.
