Four coordinated fixes for company runs permanently stalling around
tool-approval parks (project 1111 forensics + live reproduction):
- company executor dispatch loop now exits convergently when nothing is
in flight and every remaining task waits on a human: immediate parked
exit when all waiters have pending checkpoints, bounded stall ticks
otherwise. Previously it polled sleep(5) forever, hanging the turn
(observed 7.5h), never answering the user, and holding claims that
blocked any later rescue turn.
- _resume_task_checkpoint routes work-item runtime tasks through the
delegation state machine: release the human wait via the legal
AWAITING_HUMAN -> READY recovery exit, clear stale claims, and hand
the item back to the dispatcher (runtime-snapshot fallback when the
checkpoint payload lacks a plan) instead of a detached single-agent
re-run that never advances the work item phase.
- startup recovery reverse self-heal: an awaiting_human task whose park
checkpoint was already resolved (human answered, resume cut off before
the phase write) is reopened for dispatch instead of being preserved
as a wait nobody can end. Runs before the metadata-plan gate since
modern runs no longer carry the plan in task metadata.
- pause checkpoints record execution_mode from the durable
work_item_runtime marker instead of volatile task metadata, which
degraded to task_mode after a first resume and misrouted the next one.
Validated end-to-end on a live native-agent minimal-org run
(park -> approve -> re-park -> approve -> complete -> deliver, plus
synthesized crash-between-resolve-and-phase-write healed on restart).
