Zero Trust Trust-Score Scope (2D)

Zero Trust Architecture replaces "trusted inside the perimeter, untrusted outside" with a Policy Decision Point that scores every access request from live signals and re-checks that score continuously. This 2D simulator plots that policy engine as a scrolling trust-score oscilloscope: each access request is a curve tracing its own decaying trust(t) from spawn on the left to the protected resource on the right, crossing a Policy Enforcement Point gate line partway across and a dashed threshold line that decides admission. Switch between continuous Zero Trust re-verification — where a curve dipping below threshold after the gate gets revoked mid-flight — and a legacy perimeter model that samples trust exactly once at spawn and never looks again, then tune the trust threshold, decay rate and anomaly rate to watch how policy choices reshape the curves and the admitted-vs-blocked balance in real time.
