+  the pre-registration status.
+* `scripts/check-repository.mjs` now fails any completed-formalisation claim
+  ("Agda formalisation") on the two description-mirroring surfaces
+  (`README.adoc`, `CITATION.cff`), and requires `CITATION.cff` to disclose
+  pre-registration status. Regression tests cover all four cases (16 tests

+  Scanner runs on `main` are green. The 2026-09-22 billing refusals noted in
