Pcm seeded adaptive block: block predictor reset · case 02

Adaptive block reconstruction ignores its encoded anchor.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Decode independent seeded differential PCM blocks; seed is the first presented sample and declared sample count includes it, excluding padded residuals.

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	`[10, 1, 3, 2, -1, 2]`	`[10, 11, 13, 2, 1, 4]`	Failed
