cultmesh-ts reads document payloads through resolveDocumentFormatter at its five plain-msgpack sites; WireFloat carries a signalling flag and the float32 leaf refuses it; slots() refuses a key above 65535 at definition. The C# vector writer gains the 2^24+1 reads row and float32-nan.msgpack, whose committed files land in the next commit: this commit does not build its tests (union-parity numeric vectors, row count 160 and float32-nan.msgpack are absent).
