Every task sat in progress with no session, no log, and no error after the
FN-8764 role-agent rollout. Two independent deadlocks, both invisible:
1. The in-process runtime built its AgentStore but never passed it into
TaskExecutorOptions, so the executor's fail-closed role-routing gate refused
every classified node (execute/step-execute/review/merge).
2. A resumed run keeps the continuation work item it woke on active until the
interpreter returns, so the next node's principal-fence upsert violated
idx_workflow_work_items_one_active_task_continuation — a different index than
its ON CONFLICT target — and raised. The run re-suspended on every dispatch;
only an operator bouncing the card to the hold column cleared it.
Both refusals were swallowed as recoverable "principal holds" that write no log,
audit row, or task error, which is why a fully deadlocked board looked idle.
- Wire agentStore into the executor; assert the shared instance at every runtime
seam in the PG composition test.
- Supersede an active work item for a node the run has already left, then retry
the fence write once; never touch a claim on the node currently executing.
- Record task:workflow-run-suspended and task:workflow-continuation-superseded;
log principal holds, routing-unavailable faults, and fence-write errors.
