`audio-buffering.spec.js`不再先等待switchUrl完成才检查/放行网络，改为记录其

# PKG-AUDIO-BUFFER-01: observe source switching while the network is held
|
||||
|
||||
The buffering test awaited `switchUrl` before checking starvation and releasing
|
||||
the withheld response. 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. No formal review, push,
|
||||
deployment or publication was performed.
