Evidence claims:
- [sourced_fact] Working Draft dated 7 October 2026 on the Recommendation track; defines interfaces to codecs for encoding and decoding audio, video and images; does not mandate any particular codec. · source: https://www.w3.org/TR/webcodecs/
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
