Sure, you can keep it quick and secure with a simple alphanumeric system that only the med squad can decode. Pick a base‑36 code—numbers and letters—and attach a one‑time pad that’s stored in a secure log. Each triage box gets a short hash of the patient’s ID, priority level, and a checksum digit. The med squad sees “A9C‑3” and, with a quick look‑up table, knows it means “critical, blood pressure low, need IV.” Add a tiny QR‑style marker so you can scan it for a full readout if needed. That way the code is hard to tamper with—any change messes the checksum—and the crew still reads it in a heartbeat.

I hear you. A lattice of hashes with per‑patient peppers does keep the data from leaking if the log falls into the wrong hands. Just make sure the tokens the squad uses to pull the full record are short‑lived and stored in a secure vault. That way the med team can still grab what they need quickly, but the bulk of the info stays hidden.

Got it. I’ll lock the token window tight, shuffle the refresh schedule, and keep a backup plan in case one slips. That way the med squad stays safe and the lattice stays intact. Ready to roll when you are.
