The squash-merge fan-out retargeted every updated child PR onto the target branch and only afterwards pushed the new heads, batched into a single non-atomic push together with the merged-branch deletion. If the push failed (e.g. someone pushed to a child mid-run, rejecting the plain push) or a pr edit died partway through the loop, set -e aborted the run with PRs already retargeted but their heads stale - and unlike the conflict-resume path there is no label to re-trigger the action, so nothing ever repaired them. Apply the ordering the resume path already uses: push the updated heads first, then flip the bases, and delete the merged branch last (deleting a PR's base branch closes the PR, so every child must be off it first). A failed push now leaves the PRs untouched on their old base. The unit test captures the run transcript and asserts the push -> retarget -> delete order; it fails against the previous code. Also corrects the README: pushes are plain, not forced, and branch deletion is its own final step. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01JHvKryT4QUpHYdNq9YEQxX
…g-check-3njvdx # Conflicts: # README.md
Since #40 the conflict comment's fast-forward step reads `git merge --ff-only origin/<branch>`, which assert_conflict_comment_merges picks up with its `^git merge` grep, so the extracted commands never match the expected conflict merges. Skip the --ff-only line when extracting. Also trim the new comments in the fan-out push/retarget/delete sequence. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01JHvKryT4QUpHYdNq9YEQxX
The fix for the --ff-only line breaking assert_conflict_comment_merges moved to a separate PR; the e2e job here stays red until that lands and main is merged back in. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01JHvKryT4QUpHYdNq9YEQxX
A head branch can carry several PRs (one per base), so gh calls keyed by branch name can comment, label, or retarget the wrong one. Every gh call that acts on a specific PR now uses the PR number: the fan-out carries number/branch pairs from gh pr list, and the conflict-resolved run gets PR_NUMBER from the event payload via action.yml. The payload also already carries the PR's base branch, so the resume takes it from a new PR_BASE variable instead of querying the API; the resume test's gh mock no longer answers baseRefName queries, so a reintroduced lookup fails loudly. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01JHvKryT4QUpHYdNq9YEQxX

`branches: ['*']` looks like "all branches", but in GitHub's [filter pattern syntax](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#filter-pattern-cheat-sheet) the `*` glob does not match `/` — and `pull_request.branches` filters on the *base* branch. So the Tests workflow silently skipped any PR whose base branch contains a slash. Concretely: #45 is stacked on #42's `claude/...` branch and got no Tests run at all. Drop the filter — a bare `pull_request:` trigger covers every base branch. (`'**'` would too, but no filter says what it means.) The README's example workflows never had a filter, so no doc change is needed beyond the inline comment. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_01JHvKryT4QUpHYdNq9YEQxX --- _Generated by [Claude Code](https://claude.ai/code/session_01JHvKryT4QUpHYdNq9YEQxX)_ Co-authored-by: Claude <noreply@anthropic.com>

A head branch can carry several PRs (one per base), so
ghcalls keyed by branch name can comment on, label, or retarget the wrong PR — the same ambiguous-lookup family as the bug fixed in #39. Everyghcall that acts on a specific PR now uses the PR number:gh pr list(numbers forgh, branches forgit).PR_NUMBERfrom the event payload viaaction.yml.This is also an opportunity to drop an API call: the synchronize payload already carries the PR's base branch, so the resume's manual-retarget check now reads it from a new
PR_BASEenv var instead ofgh pr view --json baseRefName. The resume test's gh mock no longer answersbaseRefNamequeries, so a reintroduced lookup fails loudly.Stacked on #42 (the changes overlap in
main()); this PR retargets ontomainonce #42 lands.🤖 Generated with Claude Code
