A record now resolves to the document that owns its schema id, else one that lists it as
compatible, before the catalog name is tried; a schema renamed under a stable id opens, and an id
that names one document is not overruled by a name that names another. The name resolves a record
only when no local document has the id.
The writer refuses a write that would change which type an existing record resolves to, unless the
entries of both the existing records and the written ones own the id (a rename, the registered
descriptor wins).
Tests pin the arrived-overwrites-registered guard in both id orders, the content-hash tie-break
against the compatible-list order, sorted id processing, the cross-tier refusal and the rename, and
a cache whose document does not list the id a loaded record sits under.
