Case contract

Consume min(requested,size) slots from a ring. Report new head, count, cleared physical slots, and whether its occupied arc crossed the physical boundary.

Why this case matters

Controlled bounded deque implementation model with explicit storage and lifecycle observations.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
oversized consume	`[5, -2, [1, 2, 3, 4], false]`	`[3, 0, [1, 2], false]`	Failed
