Transaction Science 356762c294 wai-rs live_ads: presentation claims, and a spend that counts only presented impressions
A player's signed claim (WPC1) that it presented one impression of a live-ads
break: the creative's objects it presented, spans of its media time with the
fraction of pixels in view and audibility, the geometry they were measured over,
a rendered-frame count, and an optional RFC 9577 token bound to the impression
through its challenge and verified as RFC 9578 §6.4 does for type 0x0002.
An ad policy of version 2 requires claims (and optionally an attestation and an
audible run) under the video or cross-media viewability rule; the room
verifier's spend-equivalence then counts only impressions whose claim verifies.
The corpus live-conformance/presentation/ is generated from fixed seeds.
