web/room/binding.js: the side table a page carries contentBinding in until a registry lists the member (decoder and timestamp, clone, transfer, reset, a bound; ambiguity refused), the capability report built in two passes so that only codec strings the WebCodecs Codec Registry lists are put to the user agent, and the state of the frame on screen. The room routes each track before it decodes it, binds every frame its video decoders output to the verified object and group receipt, and shows the state of each tile's frame with ?debug=binding. web/binding/ runs live-conformance/browser in the page, the wasm route's verified decode, the binding through clone, transfer, copyTo and re-encode, the metadata probe and a capability report from the user agent's answers. e2e: scenario binding, energy.py for the host's per-process counter, and the decode wasm built by run.sh.
