FA-21218 / Assistive announcements / Member archive

Stale timer rolls escalation time backward · case 03

The announcement trace violates the stated escalation-ladder contract.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Unacknowledged notices have [text,level,next-due]. Open replaces notice at level0 due after2 ticks. Tick uses monotonic clock and emits at most one escalation per notice when due; levels1 and2 schedule another2 ticks, level3 is final and has no future due. Ack removes notice. Snooze adds delay to existing deadline, not now. Edit text preserves escalation level. Reset-level sets level0 and next due now+2. Report [id,text,level] speech and pending state.

Why this case matters

Deterministic controlled model of assistive announcement delivery.
