communicationOS consolidated into WAI, and its site is retired. Where these texts meant the transport they now say WAI or MoQT, and joule-moq's description, the Joule Code docs and the Three Faces tables follow. The transport example names joule-moq, which it uses, and its test drops the old name. Changelog: none Co-Authored-By: Claude Opus 5.5 <[email protected]>

transport-moqt — MoQT transport binding (the last federation layer)
A consumer binding showing a Joule Code collaboration's committed coding
operations carried over WAI's MoQT transport — the network wire
layer left deferred by spec/collab.md §2.
It closes the loop on the federation stack. The other three layers are already
built and tested in joule-code-collab:
BFT consensus (LockstepCluster), FROST threshold authorization (protected),
and MLS group keying (tests/mls_keying.rs). This example adds the transport.
What it demonstrates
The whole stack, end to end, in one in-process test:
BFT consensus (LockstepCluster) → committed, op_id-ordered coding ops
→ published as MoQT objects over WAI's transport (joule-moq)
→ each object carries a real Ed25519 / BLAKE3 signed receipt
→ a subscriber receives every op, verifies the signed receipts against the
publisher's key, and recovers the original SignedOp intact
A second test shows the ownerless-trust property: a subscriber that requires receipts rejects a group whose signed receipt does not chain to a trusted publisher key — no central authority decides who is authentic.
The transport
The carrier is inv-moq —
joulesperbit's MoQT (Media over QUIC Transport) wire protocol plus its JWP
receipt extension, the WAI broadcast-media transport. It exposes
Publisher / Subscriber / GroupHandle / Relay traits with object-level
signed provenance and joule receipts.
The test drives inv-moq through its MockFabric, which runs the real
publish/subscribe/receipt machinery in-process — real Ed25519 signatures, real
BLAKE3 merkle receipts — with no QUIC and no network. inv-moq's quic
feature is the real-wire path (quinn/rustls); the trait surface is identical, so
this binding moves to the network by swapping the fabric, not the code.
This is a standalone workspace (path-deps inv-moq from joulesperbit and the
joule-code-* crates), so the standard's reference library stays free of a
joulesperbit dependency — the same discipline as examples/l3-jouleclaw.
