 # Fallow gate: block commits that introduce new complexity or duplication
-# beyond the frozen baselines in .fallow/. Audit auto-detects the base
-# branch (typically main) and scopes to files changed on this branch —
-# the same semantics CI uses, so a commit that passes here will pass CI.
+# beyond the frozen baselines in .fallow/. Matches CI's --base argument
+# exactly (origin/main) so audit scopes to the same diff here and in
+# CI; auto-detection can pick a different ref when origin/main is
+# stale or when multiple remotes are configured, giving false-green
+# locally. If origin/main is behind, run `git fetch origin main` first.
 # To lower a baseline, refactor the flagged code and regenerate:
 #   npx fallow health --save-baseline=.fallow/health-baseline.json
 #   npx fallow dupes  --save-baseline=.fallow/dupes-baseline.json
