Archive the job when entering ARCHIVE_JOB. Add a retry endpoint that reopens FAILED_RETRYABLE without overwriting attempt history. Escalate contract-wait timeout into an OPS task, and reject RPA complete on human nodes so only task submit can leave them.
Import the existing state center, web UI, YiSaiQi callback skeleton, and project docs. Ignore local venvs, node_modules, recordings, and the duplicate state_center copy.
