Ruling (steward): add the code across C#, Rust, TypeScript and Python, each with a
captured-bytes case. details = { field: "schemaVersion", value: <offered version> }, no routingHint.
- schema (both copies), C# ForUnsupportedSchemaVersion + CultNetErrorCode.UnsupportedSchemaVersion in Rust,
TS code list, Python CULTNET_ERROR_CODES and schema catalog.
- bytes: error-vectors.json gains unsupported_schema_version (C# serializer output, checked by the
C# test, the Rust error_message.rs case, and the TS/Python vector tests; the Python builder reproduces them).
- cultnet-py interop_peer and cultmesh-py server now answer with the contract-shaped error (no extra
messageId, details {field,value}) via messages.unsupported_schema_version_error.
- tests that used unsupported_schema_version as the example of an unknown code now use not_a_code.
