FA-31075 / Keyboard interactions / Member archive

Owned repeat deadline scheduler: Concurrent repeats are emitted in key order instead of chronological deadline order · case 05

The event trace violates the deadline order rule and produces incorrect keyboard state or command output.

Case contract

Case [delay,period,events], events [kind,key,time]. First down per key emits immediately and schedules first repeat at time+delay. Tick drains every deadline at or before time, ordered by deadline then key. Up removes only that key, blur clears all. Return emissions [key,time] and sorted pending deadlines. Positive delay and period; times nondecreasing. 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.

Sample boundary fixture

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