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.
