 Forgejo Action running validate, review-standard and the secret scan; confirm
 which identities may push `ccr/*` (ops-mason first).
 
+2026-10-18: `.forgejo/workflows/ccr-intake.yaml` runs on `ccr/**` and `main`
+from exact-revision archives. On `ccr/*` it runs the intake tests and
+`credential-change.py check-branch`. That command refuses the branch unless it
+adds exactly one new CCR plus its new policy file and changes nothing else
+(not the profile, not an existing policy). The CCR must validate, be
+`proposed`, come from a listed submitter, re-pass the profile in CI and carry
+exactly the policy-as-code approval for the current profile digest. On `main`
+it runs `check-ids`. 26 tests. CCR-2026-0051 received the first automated
+platform-owner review (still `proposed`).
+
+Remaining, founder/Forgejo admin: a protected-branch rule on `ccr/*` that
+allows pushes only from ops-mason's Forgejo identity. Forgejo cannot require
+a check on main without blocking every direct push, so merging is a
+convention backed by detection: ops-mason fast-forwards only a green branch,
+and the main job plus `check-branch` evidence detect violations after the
+fact.
