Field notes

One spine, three very different practices

The largest federally qualified health center in Texas running blood pressure at population scale. A sleep medicine group rescuing PAP starts inside the ninety-day compliance window. A teleneurology network following mTBI recovery from the patient's own phone. Different specialties, different devices, different payers — the same ingest layer, threshold engine, and audit trail underneath. That is what device-agnostic means when it has to cash out.
