C#, TypeScript, Python, Rust and CultMesh refuse an unknown
cultcache.store.* header and a fifth record slot, naming the version or the
key and schemaId. The silent slot-skipping and C#'s ignored header are
deleted, and CultMesh's second record decoder is gone. Shared vectors are in
tests/vectors/document-variants-c0/. v1 stores stay byte-identical. At base,
the single-file commit's read-modify-write rewrote a v2 store as v1, which
lost data; it now refuses.
Soul passed it. Cross-runtime interop was run and passes. Three C#
Caching tests fail on Linux at both base and tip: they are Windows
share-mode tests (a FileShare.Read handle blocking delete/replace), which
cannot pass on Linux.
