The CONTRACT-01 type definitions, committed early so the session slice can build on
them while the fixtures and cross-language tests are still being written.
- scalar: Scope, RationalNs (reduced, positive denominator, 0/1 zero, checked
arithmetic and the step-v1 accumulator), SchemaRef, TypedValue with its 32-KiB
canonical-JSON cap, and the four identities that must not be confused (bus callId,
domain requestId, artifact identity, delivery/hold owner token) as distinct types.
Id, U64 and Digest call into flybus::wire instead of forking the encodings.
- canonical: RFC 8785 canonical JSON, SHA-256 digests, the operation key and the
canonical body rules of ipc-v1 section 5, with bus identities refused in a body.
- rpc, workers, media, publishing: the payloads of ipc-v1, workers-v1, state-media-v1
and publishing-v1, each with a validate step for the documented ranges, uniqueness,
ordering and bounds.
- schema: the canonical schema set, whose digest is contractDigest, declared as data
so source formatting cannot change it.
- trace: the step-v1 section 8 record, behaviour separated from operational metadata.
- seed, checkpoint: the seed derivation and FLYSESS1 envelope layout.
