openclaw agent has no cron state; a bare 'agenteval-intelligent-worker'
message made the worker skill decide then 'wait for the next tick',
deadlocking (task assigned, session never created). The trigger message now
demands '立即完成当前任务，不要等待下一节拍' and, when all sessions are
done, delegates to agenteval-intelligent-analyst. Verified end-to-end on
t480: 1h-window eval went executing -> session (2 real turns) -> close ->
report -> completed, fully agent-driven, no external IM channel.
OpenClaw cron requires a channel (announce->last fail-closed); webchat is a
Control-UI feature, not an addressable channel, and platform-side static
execution would degrade the intelligent eval into a static evaluation.
Solution (plan C): the platform keeps the scan loop and, when the queue has
a pending task, invokes the headless agent:
docker exec openclaw-eval openclaw agent --agent main \
-m agenteval-intelligent-worker --json
--deliver defaults to false, so no cron delivery channel is involved. The
worker skill runs unchanged under the OpenClaw agent (LLM decisions +
evaluator/analyst skills). Verified headless invocation returns ok.
scan_and_enqueue_tasks had no scheduler: the OpenClaw Worker wakes every
minute but the platform never enqueued executing evals, so the queue was
always empty. lifespan now starts an asyncio background task that scans
executing intelligent evals every 60s (aligned with the Worker wake),
cancelled cleanly on shutdown. Verified by a new startup test (879 total).
