 /**
  * Source-level SQL/PL/pgSQL convention linter.
  *
- * Distinct from safegres's catalog checks: it reasons about the *text* of a
- * function definition (fully-qualified references, dynamic SQL, forbidden
- * directives) rather than live-database facts, and carries no `pg` dependency.
- * safegres is its first consumer; the seam is drawn so it can become a
- * standalone `@pgsql/lint` package unchanged.
+ * This module used to carry safegres's own copy of the linter. It now lives in
+ * the standalone `@pgsql/lint` package (source text in → findings out, no `pg`
+ * dependency); safegres consumes it as "the catalog adapter", feeding it the
+ * `pg_get_functiondef` text it already reads. This file is a thin re-export so
+ * the rest of safegres keeps importing from `../lint` unchanged.
