fix(ci): make the release push survive a branch that moved mid-run - #326
Conversation
On 2026-08-24 two publish dispatches landed 38s apart. The concurrency group serialized them correctly, but `workflow_dispatch` pins `github.sha` at dispatch time, so the queued run checked out a commit from before the run ahead of it — bumped from a stale baseline, published all fifteen packages to npm, then failed at `Tag + push` with a non-fast-forward. npm ended up a version ahead of main, and fifteen 4.1.49 tags were left pointing at a commit no branch contained. Three fixes, one per link in that chain: - Check out `github.ref_name` instead of the pinned dispatch SHA, so a queued run bumps from the branch tip as it exists when it actually runs. - Push through scripts/push-release-commit.sh, which rebuilds the release commit on the current tip and retries instead of failing. By this point the packages are on npm, so this run's version strings are the truth and win; every other file comes from the newer tip. Files the tip also changed are named in a warning rather than silently overwritten. - Create tags only after the commit is on the branch, so a rejected push can no longer strand them. publish-persona.yml has the same single-release-commit shape and gets the same treatment. publish-internal-personas.yml commits once per persona inside its publish loop — a different shape this script does not model, so it is left alone. Tests run the real script against throwaway git repos: the incident replay (a concurrent release commit plus a PR merged mid-run), the unmoved-branch path, and the already-current no-op. All three fail against the previous `git push origin HEAD --follow-tags`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

📝 WalkthroughWalkthroughThe release workflows now checkout branch tips, reconcile release commits through a shared retry script, and push package tags separately. Integration tests cover branch movement, existing release files, commit ordering, and checkout configuration. ChangesRelease publishing
Merge Risk: 🟠 High · up to The release workflow can still publish packages without successfully updating the branch after its final retry, and retry reconciliation can overwrite or omit release files when the branch changes mid-run. These cases can leave npm and git inconsistent or produce an incomplete release commit, so the PR is not merge-ready until the retry loop and file-selection logic are corrected.

When the branch moves during publish-persona.yml, this default selects every package manifest and changelog even though that workflow's release commit stages only packages/personas-core/package.json. Because the persona and lockstep workflows use different concurrency groups, a lockstep release can land concurrently; lines 68–70 then replace all of its release files with the persona run's older copies, leaving Git behind the versions already published to npm. Derive the file list from the release commit's diff or pass a caller-specific RELEASE_RE.

On systems where init.defaultBranch is unset or is not main, including the inspected environment, this creates a bare repository whose HEAD is master, then explicitly pushes the seed commit to main. The next clone therefore checks out an empty master, producing an unrelated root release commit; all three new behavioral tests fail, so the Test step in .github/workflows/ci.yml cannot pass. Confirmed with git init -h, which documents --initial-branch <name> as overriding the initial branch; initialize the bare origin with main (or update its symbolic HEAD) before cloning.

🔴 Persona reconcile reverts unrelated package versions
This step runs push-release-commit.sh without setting RELEASE_RE, so it uses the default regex (scripts/push-release-commit.sh:29) matching every package's package.json and CHANGELOG.md, yet this run bumps only personas-core. On a rejected push the reconcile checks out the run-start copies of all those files over the branch tip, reverting anything that landed mid-run. A concurrent main publish that bumped every package is rolled back in git while npm keeps the new versions — the split brain this change set out to fix.

CI runs with init.defaultBranch=master, so the test's clone tracked a ref the harness never pushed and `git pull` failed. Create the bare repo with -b main and drop the pull, which was a no-op sync. Verified by re-running the suite with GIT_CONFIG init.defaultBranch=master. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two review findings, both real: - codex/Devin/CodeRabbit: selecting files by pattern over the release commit's tree also selects files the release never touched. A persona publish retrying while a lockstep release lands would have reverted all fifteen lockstep versions to its own stale base — pushing git *behind* npm, the exact failure this script exists to prevent. Take the file list from the release commit's own diff instead, which also drops the RELEASE_RE knob entirely. - CodeRabbit: the loop rebuilt the release commit on its final attempt and then exited without ever pushing it. Stop rebuilding once the attempt budget is spent, so every rebuild gets a push. Also guards a parentless HEAD and a release commit that adds nothing, and warns rather than silently skipping a path the release commit deleted. Fixtures for both: a concurrent bump of a package this release does not own must survive the rebuild, and a spent budget must fail loudly with the branch and the local release commit both untouched. Each fails against the implementation it targets. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

What happened
Two publish dispatches landed 38 seconds apart on 2026-08-24. The
publish-${{ github.ref }}concurrency group did its job — the second run queued and started 7s after the first finished — butworkflow_dispatchpinsgithub.shaat dispatch time, so the queued run checked out a commit from before the run ahead of it (both runs reportheadSha=4fbf94a0).It then bumped from that stale baseline, published all fifteen packages to npm, and died at
Tag + push:Fallout: npm served 4.1.49 while main sat at 4.1.48, and fifteen
*-v4.1.49tags were pushed pointing at a commit no branch contained. A user hitETARGET No matching version found for @agentworkforce/local-surface@4.1.48during the window wherecliwas published and its dependency wasn't yet.Failing at this step is the worst outcome available, because it happens after the packages are on npm.
Fixes
1. Check out the branch tip, not the dispatch SHA —
ref: ${{ github.ref_name }}. A queued run now bumps and changelogs from the branch as it exists when it actually runs.2. Reconcile the push instead of failing — new
scripts/push-release-commit.sh. On rejection it rebuilds the release commit on the current tip and retries (5 attempts). This run's version strings are what was actually published, so they win; every other file comes from the newer tip, which preserves anything merged mid-run. Release files the tip also touched are named in a::warning::rather than silently overwritten.3. Tag after pushing — tags are created only once the commit is on the branch, so a rejected push can no longer strand them. An already-existing tag is left alone with a warning rather than repointed.
publish-persona.ymlhas the identical single-release-commit shape and gets the same three fixes.publish-internal-personas.ymlcommits once per persona inside its publish loop — a different shape this script doesn't model — so it is left alone and still carries the original pattern.Tests

git push origin HEAD --follow-tags, and the checkout test fails when theref:line is removed — verified by reverting each and re-running.Two implementation notes worth flagging, both caught by the tests rather than by review:
