FA-49239 / PCM sample encoding / Member archive
Pcm delta reconstruction: returned seed · case 04
Cross-packet continuation returns the old seed.
Case contract
Reconstruct bounded delta-coded PCM from a seed and explicit sample-index resets before residual application, returning the continuation predictor.
Why this case matters
Offline PCM interchange uses these exact bounded packet and sample representation decisions.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| oracle 1 | [[12, 11, 14], 10] | [[12, 11, 14], 14] | Failed |
