Chase stalled contractor jobs every Monday

List every open maintenance case whose last contractor update is older than [Days without an update before a case counts as stalled] days. For each, summarize the job, the vendor, the last promise, and the evidence on file. Draft a follow-up message to the vendor asking for a dated completion commitment. Mark any case with a safety or habitability risk as an immediate human escalation. Stage the messages for approval and do not commit to any vendor terms yourself.
