live-worlds.md registers the record wai.live.world: the room authority's world statement (WLW1), the world track each actor publishes in a room ([room, principal, world], op batches one per group, receipted as a media track is, receipt alias 4), the grant attribute world = act and the scope it maps onto at a relay, the clock's lifecycle for an actor, catching up by FETCH from group 0, private worlds sealed as confidentiality seals a media track with carries into each epoch, verification and the session hash, and metering under the room's other tracks. wai-rs gains the live_world module (feature live_world): the statement, a participant's incremental copy of the world, the carry, the session hash and the verifier of section 9; and the corpus live-conformance/worlds/ written from fixed seeds by wai_live_world_vectors gen, every refusal of section 9.2 and 3.4 among its negative controls.
