+'@objectstack/metadata-protocol': patch
+---
+
+Provenance comments in `@objectstack/metadata-protocol` cite the commits that decided them, not tracker numbers that no longer resolve
+
+Clause-②: no
+
+Docblocks and comments across the package cited issue-tracker numbers that now answer 404 on GitHub.
+Each one now cites the commit in this repository's history that made the decision it describes
+(and ADR-0005's design-principle-3 correction where that record exists). Some of these docblocks sit
+on exported members, so the reworded text appears in the published `index.d.ts` / `index.d.cts`, and
+a few comments that esbuild keeps appear in the JavaScript output.
+
+Comment only: no export, type, error code, status, message text or runtime behaviour changes.
