Continue a workflow as a new run: Both predecessor and successor remain runnable · case 05

The workflow continue operation is admitted even though both predecessor and successor remain runnable.

Case contract

Return a Boolean admission decision for continue a workflow as a new run. The record r must satisfy all of: r['pending_activities'] == 0; len(r['signal_drain']) == 0; r['state_serializable'] in ['json','bytes']; r['new_run_unique'][0] != r['new_run_unique'][1]; r['predecessor_closed'] == 'continued'. 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
Both predecessor and successor remain runnable	`true`	`false`	Failed
