Cross-splice checks the incoming range without resident occupancy · case 04
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 | [[], [4, 5, 6, 14], true, 3] | [[4, 5, 6], [14], false, 0] | Failed |
