FA-49203 / PCM sample encoding / Member archive
Pcm payload valid prefix: tail range · case 03
Trailing transport bytes beyond the slot body fail sample padding validation.
Case contract
Decode a stipulated fixed-capacity PCM slot whose declared valid prefix is clamped to physical storage; verify zero padding only inside the slot.
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 4 | [[[1, 2], 2, false]] | [[[1, 2], 2, true]] | Failed |
