"""§22 S2 — collection-grained corpus mirror + collection-scoped serve/propose.

The mirror test drives cache.refresh_meta_repo against an in-memory content repo
holding entries under both the default `rfcs/` and a named collection's
`features/rfcs/`, and asserts cached_rfcs is keyed by the right collection_id."""
