✗ status_shipped · sloppy-router · node=order_lookup · CASSETTE_MISS
  tool: fetch_order
  called with: {"order_id": "9921", "request_id": "req-9921"}
  nearest recorded: {"order_id": "ORD-9921", "request_id": "req-ORD-9921"}
  diff: order_id: "ORD-9921" → "9921"   (dropped prefix)
        request_id: "req-ORD-9921" → "req-9921"   (different value)
  verdict: hallucinated_parameter
  → order_id differs from the nearest recorded call in a way that corrupts it (dropped prefix), 
which is a model error rather than a new path

  trajectory diverged at step 3: policy_check → (none); tool call 1: 
fetch_order({"order_id":"ORD-9921","request_id":"req-ORD-9921"}) → 
fetch_order({"order_id":"9921","request_id":"req-9921"})
