1.1 Certification and fallback
1.1.0-rc.1 was published, but publishing an RC did not complete every item originally assigned to
the milestone. This page records delivered code separately from certification and deferred scope.
Audited status
Section titled “Audited status”| Item | Status | What is delivered | Open work |
|---|---|---|---|
| Real-device certification | Partial | Reproducible device-matrix schema, Chromium/Firefox runs, Playwright WebKit and mobile viewport contracts | Physical Safari/iOS/Android/WebView captures and recurring device-farm evidence |
| Software codec fallback | Deferred | A capability descriptor registry and fail-closed selection diagnostics | No WASM codec ships and the media/export pipelines do not execute registered descriptors |
| Long-session durability | Partial | Resumable WebM/fMP4 checkpoints, restart recovery and an operations guide | No Service Worker/PWA background renderer and no 24-hour physical-device soak |
| Containers and images | Partial | MOV, MKV and MPEG-TS import; AVIF; deterministic image-sequence runtime | JPEG-XL and broader encode/export coverage |
| Diagnostic localization | Delivered | Stable diagnostic codes with localized message catalogs | More locale coverage remains additive work |
| Hardened fuzzing and soak | Partial | Export/transaction fuzzing and accelerated restart/soak scenarios | Continuous 24-hour sessions and wider parser corpus automation |
Remediation
Section titled “Remediation”1.2.0-rc.2 completes the image-sequence runtime path, bounds proxy input memory, and changes the
codec fallback wording/API toward a capability descriptor. CodecFallbackProvider and
selectCodecExecution remain deprecated compatibility names; they do not prove that codec work is
routed through a software backend.
1.1 is not considered fully certified until every Partial/Deferred row has its own reproducible evidence. Product capability UI must continue to use exact runtime preflight and fail closed.
