C2a F2, operator: "CultCache never destroys or relabels a record it doesn't
understand; keeps it byte-for-byte, refuses writes that would overwrite it."
- The registry's claim decision (Claimant) is split out of resolution. It
never decodes or compares shapes, so a store classifies a record from its
header. The last branch, "No local CultCache schema matches", now means
foreign instead of a refused load.
- Both store kinds keep a foreign record out of the cache and list it in
CacheBackingStore.ForeignRecords (key, schema id, catalog name, storedAt).
- Single-file store: a whole-view write lays back every foreign record the
file holds now, with its catalog entry, and keeps a marked header while it
carries one (it cannot see their ids). A staged write, a commit (onto the
file or whole view) and a whole view over a key the file holds as foreign
refuse with CultSchemaConflictException naming the key and id. A merge
judgement never decodes a foreign record, and one that replaced a held
record takes it away.
- Directory store: a foreign record's page is never read; a generation that
would replace or remove one refuses before any page is written.
- Contracts: hard rejection no longer lists "no compatible local schema
candidate"; the persistence format says what a foreign record is.
