+// Scope-enum extension: historical commits use scopes (`benchora`,
+// `design`, `elicitate`, `phase4`, `phase5`, `release-please`, `wp15`,
+// `wp17`) that are outside the original 10-scope enum. Adding them to
+// the enum unblocks `lint-commits` for future merges into `main` without
+// requiring a force-push to rewrite provenance.
+//
+// subject-case: relaxed to `[0]` (disabled) because legitimate commits
+// reference proper nouns (`WP-25`, `Rust`, `Harbor`, `SPDX`) and version
+// tags (`v0.5.1`) that the binary `lower-case` rule rejects. The rule
+// doesn't catch real bugs in this codebase; type-case is still enforced
+// (lowercase on the commit type).
