Cold adversarial review returned BLOCKED on the documentation half. Addressed:
- The new decision record carried no lifecycle metadata block, taking the repo from
82/82 to 83/82 and making it invisible to the by-key catalog lookup that #521
established the same day. Added key/status/since/supersedes/superseded-by
(ffmpeg.qsv-extra-hw-frames-floor) and regenerated docs/decisions/README.md;
decisions_validate.py now reports OK with no legacy-unmigrated notice.
- The entry claimed to correct the #350 record but left that record untouched, so the
stale "the burst is bounded" claim stayed authoritative for anyone resolving
ffmpeg.hls-cold-start-burst. Added a forward-pointing correction note there (hence
the [decisions-edit] token on this commit).
- The floor was applied silently. QsvPipelineBuilder.SetAccelState now logs a warning
naming both the configured and applied value, because raising a deliberately small
pool costs additional surfaces (64 NV12 1080p surfaces is roughly 190 MiB, 760 MiB
at 4K) on memory-constrained iGPUs.
- Narrowed an overstated claim in the entry: 1..63 are untested, not known-bad. We
raise them because the risk is a channel serving nothing, not because asking for
less is illegitimate. Recorded as a deliberate over-reach with a stated cost.
- Corrected a factual error: SubtitleScaleQsvFilter also formats extra_hw_frames but
is dead code with no construction site, so it is NOT covered by the guard.
- Config-vs-behavior mismatch: Create/UpdateFFmpegProfileHandler now normalize on
save so stored rows converge on what the pipeline runs, and the SPA field carries
min=64 rather than defaulting the display to 0. Render-time flooring is kept as the
net that fixes existing deployments with no migration; the remaining gap for
un-resaved rows is recorded as an accepted residual.
- Tests strengthened: pinned to the literal measured 64 rather than to the constant
(so lowering the floor cannot quietly satisfy them), added a negative-value case,
added a deinterlace-upload case, and replaced the narrow ShouldNotContain with a
regex asserting EVERY extra_hw_frames occurrence in the command is >= the minimum.
Negative control re-run against the strengthened tests: reverting the floor fails 5,
with the build verified succeeded first. Full suite green (4086 .NET, 891 web).
Review finding that needed no change: the "single point" claim was independently
verified — no bypass exists, every FFmpegState construction routes through
MaybeQsvExtraHardwareFrames.
