Case contract

A delivery is keyed by (utterance, generation). Submit replaces pending text for that key. A receipt is accepted only for the active generation and exact serial; accepted receipts append spoken text, remove pending, and retire the serial. Disconnect discards pending, increments generation, resets serial. Duplicate receipts do nothing. Report spoken, pending count, generation and next serial.

Why this case matters

Deterministic controlled model of assistive announcement delivery.
