WAI is a container + capability-dispatch standard for media. It does not re-implement codecs; it dispatches to SOTA standard libraries (PNG, FLAC, zstd as the mandatory floor; AVIF, JPEG-XL, Opus, AV1, XZ as the recommended modern set) and adds an envelope that lets a neural shared-prior path coexist with the model-free floor. The capability a file requires is named, not supplied. Two paths open every conforming file: the neural condition (sink regenerates from a shared ambient prior) and the zeroth condition (registered SOTA codec menu). Apache-2.0. Adds: - wai/SPEC.md — WAI v1.0 spec (envelope, manifest, capability dispatch, registered capabilities including v1.1 multi-rendition extension) - wai/wai-rs/ — Rust reference implementation: lib + cdylib + staticlib, C FFI, 11 capability + envelope round-trip tests passing - wai/wai-web/ — wasm-bindgen wrapper for browser sinks - wai/wai-neural/ — Python tooling for neural-condition models - wai/tools/ — codec export + encode helpers (Python) - wai/corpus/CORPUS.md — third-party test corpus reacquisition guide Updates README.md to list four standards instead of three. Known consumer: CommunicationOS uses WAI for media transport over MoQT/MLS sessions. Co-Authored-By: Claude Opus 4.7 (1M context) <[email protected]>
