Remove `git fetch */origin` when fixed upstream

[strawgate]

github/gh-aw#16925

[github-actions]

TL;DR: we should not remove the git fetch ... refs/remotes/origin/* workaround yet, because the upstream bug is still open (github/gh-aw#16925); keep this issue as a tracker and remove it right after upgrading to a gh-aw version that contains the fix.

Recommendation

Keep the current workaround in place for now, and gate removal on two conditions: (1) upstream issue github/gh-aw#16925 is closed with a released fix, and (2) this repo upgrades GH_AW_VERSION to that release and validates PR assistant push behavior.

Findings

• The workaround is currently active in the reusable workflow shim:
  • .github/workflows/gh-aw-mention-in-pr.md:68-76 (Ensure origin refs for PR patch generation with git fetch --no-tags --prune origin '+refs/heads/*:refs/remotes/origin/*').
• It is compiled into the lock workflow used by consumers:
  • .github/workflows/gh-aw-mention-in-pr.lock.yml:666-667.
• This mitigation was introduced by merged PR #220 as a fix path for issue #206.
• Upstream root-cause issue remains open:
  • github/gh-aw#16925 state is open.
• Current gh-aw version pin in this repo is:
  • Makefile:4 (GH_AW_VERSION := v0.45.1), compiled via Makefile:126-128.

Verification

I verified current behavior and repo health with existing commands:

$ make lint-workflows
Setting up actionlint...
Downloading actionlint v1.7.10...
✓ actionlint installed to bin/actionlint
Validating GitHub Actions workflow files...
Checking claude-workflows/issue-triage/ro/example.yml...
...
Checking claude-workflows/build-failure-github-actions/rwx/example.yml...
(exit code 0)

And confirmed the workaround locations:

$ rg -n "Ensure origin refs for PR patch generation|refs/remotes/origin/\*" .github/workflows/gh-aw-mention-in-pr*
.github/workflows/gh-aw-mention-in-pr.md:68:  - name: Ensure origin refs for PR patch generation
.github/workflows/gh-aw-mention-in-pr.md:76:      git fetch --no-tags --prune origin '+refs/heads/*:refs/remotes/origin/*'
.github/workflows/gh-aw-mention-in-pr.lock.yml:666:        name: Ensure origin refs for PR patch generation
.github/workflows/gh-aw-mention-in-pr.lock.yml:667:        run: "...git fetch --no-tags --prune origin '+refs/heads/*:refs/remotes/origin/*'..."

Detailed Action Plan

1. Monitor github/gh-aw#16925 and wait for closure + release notes indicating the push_to_pull_request_branch patch generation fix.
2. Update Makefile:4 (GH_AW_VERSION) to the fixed upstream version.
3. Remove the temporary fetch step from .github/workflows/gh-aw-mention-in-pr.md:68-76.
4. Recompile workflows so lock files match source:
   • make compile
5. Validate workflows:
   • make lint-workflows (or make lint)
6. Run an end-to-end smoke test on a same-repo PR using /ai in an issue_comment:
   • request a tiny code edit,
   • confirm push succeeds without reapplying old commits,
   • confirm no regression vs current behavior.
