 ## Pre-push vs CI
 
 - **Pre-push** (`.githooks/pre-push`): Runs unit tests, `cargo audit`, web build+test. Does *not* run mutation (too slow for every push).
-- **CI mutation job**: Runs `cargo mutants -f storage_json` (or one crate) on a schedule or on PRs to main. Fails if "missed" count increases beyond the baseline in this doc.
+- **CI mutation job**: Runs `cargo mutants -f '*storage_json*'` on PRs/push to main. Fails if "missed" count increases beyond the baseline in this doc.
 - For a quick local push without full checks: `git push --no-verify` (use sparingly; CI will still run).
