4SI / INTERACTIVE EXPERIENCEABOUT 90 SECONDS

Physical evidence before action.

A valid credential can carry a claim. Presence adds a physical verification boundary at the moment of consequence.

One action.
One unresolved question.

JavaScript is required for the interactive sequence. The central distinction remains: valid credentials do not by themselves establish the physical authority behind a consequential action.
