ci: diff changed files against the PR target branch#340
Merged
Conversation
The "List All Changed Files" step always diffed against origin/main, so PRs targeting v2 swept every v2-vs-main difference (.gitignore, etc.) into the filename validation and flagged them spuriously. Diff against v2 when the PR targets v2; otherwise diff against main (unchanged for main and workflow_dispatch). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
