Pcm biphase mark payload: validity output · case 02

PCM payload value is confused with line-code validity.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Decode stipulated biphase-mark PCM transport cells: every cell must transition at its start, midcell transition is one, and final physical level carries across packets.

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	`[[0, 1, 0], [false, true, false], 0]`	`[[0, 1, 0], [true, true, true], 0]`	Failed
