A hospital sends an encrypted finding. An untrusted evaluator computes the triage decision over ciphertext only. The hospital alone decrypts the answer. This page replays one real recorded execution and re-verifies it in your browser.
The policy thresholds are public and encoded on the evaluator side; only the patient's values are encrypted. Threshold confidentiality is not claimed — this is an encrypted patient value evaluated against a public threshold, not an encrypted threshold.

The replay above is a recorded execution. This is different: run one genuine programmable bootstrap right now on this machine — encrypt a synthetic diameter, threshold it over ciphertext, decrypt the flag. Real elapsed time, real instrumented count (~14 s).

Live cryptographic execution is disabled on this public deployment. The verified captured replay above is the primary surface; the recorded execution was independently verified and content-pinned.
RAD-TRIAGE-DEMO — synthetic / non-clinical. This page is a renderer outside the trust boundary; it establishes no cryptographic truth itself. Fresh execution and independent decryption are not claimed by the recorded replay. · Author: Eric Beans, CEO, H33.ai, Inc.
