CultMeshContentVectorTests writes content-acceptance-vectors.json (what the reference accepts, refuses, rewrites and
keys over nil, arity, trailing, integer/float, string-family and invalid-UTF-8 shapes), extends the record-key
vectors with the prefix-fold, fallback-hash traps, and the TS writer adds a whitespace-version, padded kind and
MIME pack vector. GameCult.Mesh exposes internals to its test project so the judge can call ValidateManifest.
The generated files follow.
