/**
 * Regression / migration-gate test for #551 and ADR-457 (TS migration).
 *
 * ESLint must apply the correct policy to every msd-core/bin/lib/*.cjs
 * file as modules migrate from hand-written CJS to tsc-generated artifacts:
 *
 *   - tsc-generated artifact (has src/<basename>.cts counterpart) → MUST be
 *     eslint-ignored.  We lint the *.cts source instead (ADR-457).
 *   - Genuinely hand-written (no src/*.cts counterpart) → MUST be linted
 *     (NOT ignored).  Includes scripts-generated package-identity.cjs which
 *     has no *.cts source.
 *
 * The test is filesystem-driven — it scans bin/lib at runtime and checks each
 * file against the src/ directory, so it stays correct automatically as more
 * modules migrate.  No hardcoded lists.
 *
 * ESLint behaviour is verified via ESLint's own `isPathIgnored()` API so the
 * test reflects real resolved flat-config precedence, not a textual scan of
 * eslint.config.mjs.

// This invariant used to fail any docs/workflows/README file that contained

// RETIRED workflow-advance command and any occurrence was a stale reference
// that should have read `/msd-progress --next` instead.
//
// That premise is now obsolete. #2903 established that human-facing docs
// must use the hyphen command form (`/msd-<cmd>`), and the maintainer
// resolved the #3054-vs-#2903 conflict in favor of retiring this invariant
// (option B) rather than exempting `next` from the #2903 sweep (option A):
// `/msd-next` no longer names the retired workflow-advance command — it is
// the correct, live, user-facing name for the state-aware smart-entry
// launcher (`commands/msd/next.md`), exactly as documented by
// `docs/FEATURES.md`'s REQ-CONSOLIDATE-03 ("`/msd-next` is not the retired
// workflow-advance command; it is reserved for the state-aware smart-entry
// launcher. Workflow advancement remains under `/msd-progress --next`.").
//
// Keeping this scan alive would now contradict the documented command form:
// it would fail the build the moment `/msd-next` legitimately appears in
// docs, which #2903 requires everywhere `next` is referenced. See #3054,
// #2903, and docs/FEATURES.md REQ-CONSOLIDATE-03.

 * `msd-sdk` / `MSD_SDK` reference cannot creep back into a shipped prompt or hook
 * and re-introduce drift between the documented surface and the supported
 * `msd-tools` binary.
 *
 * Scope: runtime surfaces only — the prompts and hooks the installer ships into
 * a user's runtime config dir. Explicitly NOT covered here:
 *   - `bin/install.js` — installer code, not a runtime-deployed prompt/hook
 *     surface. (It carries zero `msd-sdk` references today; the SDK-shim
 *     verification subsystem was removed in #515 and the shim retired in #522.)
 *   - `msd-core/bin/` — executable library code, not deployed prompt text; it
 *     may legitimately reference the SDK retirement in comments.
 *   - `tests/`, `docs/`, `.changeset/`, CI/lint scripts — legitimately reference
 *     the SDK retirement as history or detect its stale artifacts.
 *
 * Complements `tests/msd-tools-path-refs.test.cjs`, which only catches the
