What this page is
No one has written this case yet. Everything on this page is derived from the pull-request record by the same deterministic rules as the corpus: a feature or infrastructure merge opens an arc, and bug fixes, refactors, tests, and docs on the same surface within forty-five days follow it. Titles are verbatim from GitHub. Nothing here is a claim beyond the record.
