The test/migrations jobs check out fetch-depth:1. A shallow clone has NO origin/<base> tracking ref and no merge-base, so the three-dot origin/main...HEAD errored -> empty diff -> docs_only=false -> EVERY docs-only PR silently ran the full matrix (safe but the skip never fired). git fetch always writes FETCH_HEAD, which resolves in a shallow clone; diff against it with a two-dot tree diff (no merge-base). Confirmed in a real shallow file:// clone: origin/main did NOT resolve and three-dot errored, while FETCH_HEAD two-dot correctly returned the docs file. api-docs/format were unaffected only because they use fetch-depth:0.
