Pcm channel status block: status bit mask · case 04

Transport status high bits leak into the one-bit channel-status lane.

Member previewVariant 4 · 3 implementations · 8 checks per implementation

Case contract

Group stipulated audio subframes into fixed-size channel-status blocks, preserving PCM samples and one status bit; a new start marks prior partial data incomplete.

Why this case matters

Offline PCM interchange uses these exact bounded packet and sample representation decisions.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
oracle 1	`[[[[[1, 3], [2, 0], [3, 1]], true]], []]`	`[[[[[1, 1], [2, 0], [3, 1]], true]], []]`	Failed
