Transaction Science c70aedef60 wai: stitched presentation — player-signed claims of stitched and interstitial ads, the signed pod-input record, ad frames in live-compose
wai.video.stitched_presentation (extensions/stitched-presentation.md): a WPS1 claim names an ad
by the marker the stream carries for it (an EXT-X-DATERANGE tag, an interstitial's asset, a DASH
event) in the manifest it states the SHA-256 of; a WPI1 pod-input record, signed by the
stitcher or a proxy in front of the ad server, binds the response digest, the chosen ads, their
creatives and prices, the avail, the frame and the measurement terms; a verifier recomputes
each ad's presentations, quartiles and the spend that counts by currency. A form-1
wai.video.ssai receipt gains a JSON carriage (its signed bytes unchanged) so it can be a
record's response. live-compose gains the squeeze and double-box ad frames (§5.9). Corpus
live-conformance/stitched/, its independent verifier stitched_presentation_verify.py, and the
browser producer web/ads/stitched.js with tests against the corpus.
