The unique-index rule refuses a variant that inherits its base's [CultIndex]
value, so the vector's laser-big now carries a code override. Written by the
code under test through the production path; the other runtimes still refuse
it by version and by the laser-big key.

F3: an override drifts exactly as the same member would on a plain record. A
slot the type dropped is ignored and reported by the store's schema resolution
(LastSchemaMigrationReports), the one surface a plain record uses; a value that
no longer decodes refuses the load, naming the variant and member. The second
report surface (VariantMigrationReports, the per-variant report map, the
catalog slot-name plumbing) is deleted.
F4: an override for a slot the type does not have, or a value that does not
decode as the member, is refused at write. Drift is for type changes after the
fact, not for bad writes. F5: two overrides of one slot are refused.
F2: a variant that shares an indexed value with another record is refused,
naming both keys and the index (the R6 rule extended to [CultIndex]); plain
record duplicate handling is unchanged.
F7: a flatten now resolves against the same batch, so a base edited in that
batch is in the flattened record; and the directory store refuses to load a
variant page as it refuses to write one.
The C1 vector's big variant now overrides its indexed code, as the unique-index
rule requires.

VariantTests drive the cache batch API and the real single-file store. The C1
vector was written by the code under test through that path; C# reads it and
rewrites it byte for byte, and the other runtimes' tests read the same bytes next.
The C0 tests that expected C# to refuse a v2 store now expect what C1 does with
it.

The legacy catalog layout reaches CultMesh's fallback reader, and a nil header
was the only defaulted header; each gets one vector or test. The C# store
tests catch the refusal where the store attaches.

An unknown store header, a record slot beyond four with a full payload, the
v2 variant record C1 will write, and a v1 store written by the base-commit
Python writer. Every runtime's tests read these bytes.
