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.

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.
