FA-98134 / Sequence batch packing / Member archive
Flattened packed tokens retain the wrong owner indices · case 04
Flattened packed tokens retain the wrong owner indices.
Case contract
Flatten sequences in order and return parallel zero-based sequence-owner IDs for every token.
Why this case matters
This deterministic toy packing rule models a common boundary in preparing bounded training sequences.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| ownership lengths | [[4, 2, 3, 3, 3, 3], [1, 1, 2, 2, 2, 2]] | [[4, 2, 3, 3, 3, 3], [0, 0, 1, 1, 1, 1]] | Failed |
