…erge base' The patch-coverage gate did 'git fetch origin <base> --depth=1', truncating the base to one commit with no common ancestor with the PR branch whenever the branch was behind base — so diff-cover crashed with 'fatal: origin/<base>...HEAD: no merge base' and reded coverage on PRs that were merely stale (hit repeatedly). The checkout is already fetch-depth:0, so a plain 'git fetch origin <base>' resolves the merge-base reliably. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The patch-coverage gate fetched the base with
--depth=1, leaving no merge-base with a PR branch that's behind base → diff-cover crashed withfatal: origin/<base>...HEAD: no merge baseand reded coverage on merely-stale PRs (hit repeatedly this week). Checkout is alreadyfetch-depth: 0, so a plaingit fetch origin <base>resolves the merge-base. One-line fix + rationale comment.🤖 Generated with Claude Code
