Padding bits are decoded as extra compressed symbols · case 04
Padding bits are decoded as extra compressed symbols.
Case contract
Decode exactly count one-bit symbols from integer bytes in LSB order. Count is valid and padding is ignored.
Why this case matters
A small offline codec model isolates a compression-specific failure without external files or libraries.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.

|---|---|---|---|
| valid zero suffix | [1, 0, 0, 0, 0, 0, 0, 0] | [1, 0, 0, 0, 0] | Failed |
