Posture is offered as buyer risk-removal — not a marketed legal moat.

P.AI is architected inside the FDA §3060 / 21st Century Cures Clinical Decision Support carve-out: evidence-cited considerations surfaced to a licensed clinician who remains the decision-maker, with per-flag provenance and hash-chained attestation. We present this as procurement hygiene that de-risks the buyer; the durable moat is the validated corpus, clinician network, and verified-encounter ledger.
