Fire a durable workflow timer: A timer fires before its scheduled timestamp · case 03

The workflow timer operation is admitted even though a timer fires before its scheduled timestamp.

Case contract

Return a Boolean admission decision for fire a durable workflow timer. The record r must satisfy all of: r['fire_time'][0] >= r['fire_time'][1]; r['timer_not_cancelled'] is False; r['timer_generation'][0] == r['timer_generation'][1]; r['workflow_not_terminal'] not in ['completed','failed','cancelled']; r['fire_once'] is False. Extra tracing fields are ignored; validation does not mutate the record.

Why this case matters

A deterministic local contract for workflow orchestration. Each negative fixture violates exactly one invariant. No transport timing, persistence, cryptographic verification, or full protocol implementation is claimed.

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
A timer fires before its scheduled timestamp	`true`	`false`	Failed
