What this patent covers
A method for separating trusted instructions from untrusted data by tagging each with its trust level and sealing the separation under an operator-controlled signature. Untrusted data cannot acquire instruction authority, and any attempt to inject instructions through a data channel is contained by capability gating, with the containment recorded for audit. Filed 01 to 02 June 2026 as GB2612783.7.
