/**
 * Regression guard for issue #556 — retire orphaned CJS↔SDK hand-sync tooling.
 *
 * The @opengsd/gsd-sdk package boundary was retired (ADR-0174, #191/#192) and
 * the `sdk/` tree is no longer tracked. The generator-based hand-sync lint that
 * policed CJS-vs-SDK TypeScript drift is therefore dead infrastructure: it
 * referenced an `sdk/src` tree that no longer exists and was wired into no CI
 * workflow or npm script. This guard asserts it stays removed.
