Cross-splice checks the incoming range without resident occupancy · case 03
Cross-splice checks the incoming range without resident occupancy.
Case contract
Move a half-open slice from one deque to another at a valid gap. Reject overflow atomically. Return [source,destination,accepted,moved].
Why this case matters
Controlled bounded deque implementation model with explicit storage and lifecycle observations.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| overflow | [[], [3, 4, 5, 13], true, 3] | [[3, 4, 5], [13], false, 0] | Failed |
