+## PR Review Report Format
+
+When reporting a PR for audit review, copy review-surface file paths verbatim
+from `git diff --name-only` or `git show --name-only --format=` output. Do not
+retype paths from memory. A mismatched path in a review report is an

+
+## Historical Disclosure Publication
+
+The historical provenance disclosure remains a draft while it is named
+`docs/ops/historical-provenance-draft.md`. Final policy publication is a
+two-step operation in one verified PR:
+
+1. Remove draft-specific language and fill the authorized baseline date and
+   baseline tag.
+2. Rename the file to `docs/ops/historical-provenance.md` so the canonical
+   public disclosure is discoverable without the `-draft` suffix.
+
+Do not publish the disclosure as operative policy until both steps land
+together and the auditor explicitly authorizes publication.
