// A rule policy module can compute violations correctly and still never run, if its entry in
// LAYERING_RULES is missing or its id is missing from LAYERING_RULE_IDS. The registry makes
// duplicate registration unrepresentable on its own (an object holds a key once, and oxlint's
// no-dupe-keys rejects the attempt), so what is left to check is the other direction: that the
// catalog and the registry still describe the same set of rules.
// scripts/ is outside tsconfig.json's `include`, so the Record's exhaustiveness is an editor
// signal, not a CI gate — this test is what fails the build when wiring goes missing.
