Ids become gamecult.model.*.v3. Every document is encoded by one named
MessagePack codec in contract.rs with unknown fields refused, and publishes a
JSON Schema generated from its type (schemas/). The envelope's ciphertext is
binary. Each frame is a cultnet.operation_request.v0 / operation_response.v0
for service gamecult.model.connector, operation invoke, its message_id the
request id, its payload the base64 of the sealed envelope; the carriage is
checked before any decryption. frame_bytes_for_payload and
payload_bytes_for_frame measure the carriage. Golden v3 fixtures and their
generator (tests/wire_golden_v3.rs) pin drift. The test debt of the kit lift
(each identity field, each contract_refusal arm, request ids measured in bytes)
is paid in the rewritten code.
