Self-splice extracts the range from its successor boundary · case 05
Self-splice extracts the range from its successor boundary.
Case contract
Move a range within one bounded deque, preserving size and stable element identity. Gaps inside or at either boundary of the range are no-ops.
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 |
|---|---|---|---|
| move left | [8, 9, 5, 6, 9] | [7, 8, 5, 6, 9] | Failed |
