FA-31015 / Keyboard interactions / Member archive
Release activated command binding: A release disarms unrelated bindings or leaves its own binding armed · case 05
The event trace violates the up disarm rule and produces incorrect keyboard state or command output.
Case contract
Events [kind,key,owner]. Down arms a key for its owner; repeated down preserves the original owner. Up emits key only for matching key and owner then always disarms that physical key. Cancel clears all pending keys; owner-left clears that owner. Return emitted key-owner pairs and sorted pending pairs. Inputs are finite ordered event traces; return the stated deterministic state. Batch entries are independent. N varies the number of independent input transactions.
Why this case matters
Controlled keyboard event processing model for debugging application event logic.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
