Deliver a signal to a durable workflow: An unknown signal type bypasses workflow dispatch · case 02

The workflow signal operation is admitted even though an unknown signal type bypasses workflow dispatch.

Case contract

Return a Boolean admission decision for deliver a signal to a durable workflow. The record r must satisfy all of: r['signal_identity'][0] not in r['signal_identity'][1]; r['recipient_run'][0] == r['recipient_run'][1]; r['signal_declared'][0] in r['signal_declared'][1]; r['mailbox_capacity'][0] < r['mailbox_capacity'][1]; r['sequence_dependency'][0] <= r['sequence_dependency'][1]. 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
An unknown signal type bypasses workflow dispatch	`true`	`false`	Failed
