Execution Model — 
Codex Sovereign v10

Codex Sovereign v10 operates as a deterministic governance control plane.

Every AI-driven action is intercepted before execution and evaluated for admissibility.
No action proceeds without validated authority, complete decision state, and satisfied constraints.

Outcomes are enforced structurally - execute, refuse, or escalate - not suggested.

All decisions are recorded as replay-verifiable custody artifacts, providing proof that governance held at the moment of action.

Deterministic Control Plane

Every action passes through governance before execution - no direct path from signal to effect.

Admissibility Resolution

Inputs are evaluated and classified as admissible, inadmissible, or indeterminate.
Execution is permitted only when admissibility is fully resolved.

Authority & Policy Validation

Authority (who can act) and policy (what is allowed) are validated in-state, independent of the originating system.

Refusal Rails & Escalation

When conditions are not met, actions are refused, escalated, or rerouted before execution.
Refusal is enforced structurally - not advisory.

Custody Logging & Replayability

Every decision, approval, refusal, and execution event is recorded in tamper-evident custody logs that support full replay and auditability.

Interpretability & Traceability

Decisions are interpretable in plain language and traceable through verifiable governance artifacts, including cryptographic evidence of custody at bind.

How It Differs From Governance Theater

Most governance systems operate after the fact.

Codex Sovereign operates at the moment of action.

• Not dashboards — does not describe outcomes after the fact 
• Not monitoring — does not observe without intervening 
• Not redaction — does not mask risk without control

Governance is enforced at the moment an action becomes irreversible.

Custody Log + Replay Evidence

No action executes without proven admissibility.

Most AI governance explains what happened.
Codex Sovereign determines what is allowed to happen.
