impossible files a defect

When the step cannot ever be performed on this machine, deferring forever is the wrong answer. Sealing deficient with a procedure defect is how the procedure gets fixed for every future job.

The answer conformed to the contract and every assertion held.

What the model was given

System instructionassembled from the contract schema, not hand-written

You own this job for its whole life. A step cannot be performed. Decide what now happens to the job, the machine, the customer booking and the parts order. You may be woken days from now, so anything you need later must be written down here.

Return JSON with these fields:
- status (one of deferred | waived | impossible, required): deferred keeps the job open and the machine held. waived requires a named person with standing and releases the machine. impossible seals deficient and files a procedure defect.
- action (one of chase | reorder | escalate | revise, required)
- rationale (string, required): Why this disposition and not the others. This is read by a person in a dispute months later.
- chase_after (string, null when it does not apply): ISO 8601 UTC. When to wake and check. Required when action is chase.
- reorder_part (string, null when it does not apply): Required when action is reorder. A purchase order is DRAFTED, never sent.
- escalate_to_role (string, null when it does not apply): Required when action is escalate. The role that must decide, not a person's name.
- hold_machine (boolean, required): Your recommendation. The Gate decides deterministically from the record; you do not hold anything yourself.

What came backStructured output, not prose that was parsed afterwards: the contract schema is posted as the response schema, so the model returns this shape or fails.

{
  "status": "impossible",
  "action": "revise",
  "rationale": "The procedure is incorrect for the Segway Xyber v3, which uses a sliding pin caliper rather than a lower caliper bolt. This is the third job to encounter this blocker, indicating a systemic template error. Marking the job as impossible to file a formal procedure defect and trigger a template revision. The machine must be held because the front brake service is incomplete and safety-critical.",
  "chase_after": null,
  "reorder_part": null,
  "escalate_to_role": null,
  "hold_machine": true
}

What this scenario asserted

Assertions pin the part of an answer that decides something, never the whole object — exact-matching a rationale would fail the first time it was reworded, and a suite that cries wolf is abandoned inside a day. Where the reasoning is checked at all, it is to catch an agent that reached the right verdict for no reason.
