Neural override verification and constraint architecture for sovereign AGI execution

A system comprising one or more processors and a non-transitory memory storing instructions that, when executed by the one or more processors, cause the system to enforce a fail-closed logic-execution gate for an AI agent by:

• (a) encoding, at deployment, agent logic into an Immutable Constraint Chain (ICC) and anchoring a commitment of the ICC in an append-only verifiable log that publishes signed heads, wherein at runtime the system verifies an inclusion proof relative to a current signed head under a freshness policy and, upon head advance, verifies an append-only-evolution (consistency) proof;
• (b) within a read-only Encrypted Logic Vault (ELV), generating for each execution request a behavioral profile comprising at least a behavioral index, a temporal context, an instruction class, and an entropy-slope metric, and comparing the profile to the ICC;
• (c) verifying purpose alignment using a Purpose Enforcement Kernel (PEK) against a Mission Identity Template (MIT);
• (d) verifying license authority via a licensing gate (GLG) including tier validation and an m-of-n quorum signature threshold;
• and
• (e) responsive to (a)-(d) passing, minting an execution permit, recording the permit in an Immutable Arbitration Ledger (IAL), and requiring an unexpired permit identifier for subsequent agent actions;
• otherwise causing execution to fail closed with a disposition selected from HOLD, QUARANTINE, DENY, or ESCALATE, wherein each evaluation binds a nonce and a monotonic counter.
