Nested list decoding ignores child validity · case 02
Nested list decoding ignores child validity.
Case contract
Gather selected list rows from offset-based child storage. Parent nullness hides child storage; empty valid lists remain []; child nulls remain None. Preserve repeated selected rows and list element order.
Why this case matters
A bounded deterministic data engine model makes representation and changelog faults reproducible.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| null child | [[2, 3]] | [[null, 3]] | Failed |
