Switching can await `canplay` and resumed playback, so +this could stop the test from releasing the bytes needed to complete the switch. +Earlier installed WebKit traces stopped at this await. The initial current-source +rerun instead reached the existing native-starvation failure; these observations +are preserved separately. + +`beginAudioSwitch` now starts the real switch without returning its Promise to +Playwright. It records pending/fulfilled/rejected status and timestamps. The test +can observe the actual HTTP gate while switching, then requires fulfillment after +release. Rejections cannot produce a passing result. Original trusted `waiting`, +nonzero time, stalled-audio behavior, recovery, synchronization and media-error +assertions remain. Phase, switch and media observations are attached before cleanup. + +A new regression withholds every encoded frame while sending complete `ftyp` and +`moov` boxes from the existing MP4: 1,605 bytes derived from box sizes. It requires +a held request and pending switch, then releases the network and checks fulfillment +and resumed video/audio clocks. This tests orchestration, not ongoing playback +starvation. An initial one-byte fixture caused all four Firefox combinations to +reject with a native media error; that failed run is retained. The final fixture +sends complete format/metadata boxes instead of accepting those errors. + +With the final fixture, reinstating the exact old await expression reproduced a +20-second Chromium timeout in `begin-switch`, with 1,605 bytes sent and the request +held. The corrected source was restored byte for byte. All 12 corrected cases +pass: published/current core crossed with published/current Audio Track in +Chromium 153.0.8010.12, Firefox 155.0 and Windows WebKit 26.6, without retry/skip. + +The separate original starvation matrix remains 16 passed and 8 failed. All +failures are Windows WebKit at the trusted native-starvation assertion; two video +cases have pending switches and two have fulfilled switches. Completion and +starvation therefore remain separate observations. AUDIO-BUFFER-01 is not waived. +The final metadata correction changes only the new case; original starvation +inputs/assertions and the shared helper retain the tested bytes. These separate +runs must not be described as a fully green 36-case suite. + +Canonical Node 24.21.0/Yarn 1.22.22 were used. Three real HTTP gate unit tests and +read-only spec lint pass. The [validation record](../baselines/audio-buffer-order-validation.json) +retains run summaries, input provenance, report hashes and phase/media/request +evidence. Candidate browser inputs are source builds, not installed npm tarballs. +No production API/code, media fixture, gate server, timeout, dependency or +distribution changed. This closes test ordering only; PKG-AUDIO-05/06 and native +buffering/device acceptance remain outstanding.
