+  Religion Council" note. Historical documents (CHANGELOG history, ADRs, committed benchmark
+  reports, review records) are left as written.
 - Deferred follow-up: rename the older controller `renderer-bypass` boundary reason to
   `verification-artifact-missing`. The reason-code string may be a public contract, so this needs a
