Drift Stack™

Enterprise AI Execution Governance Architecture

A five-layer architecture for preserving coherence as intelligent systems interpret, decide, and act. Identity and frame establish governing context. The Coherence Boundary contains the Ledger Layer, execution contract, admissibility decision, and Execution Boundary. Drift is measured against that structure, and external correction restores alignment when authoritative reality changes.

The Drift Stack layered architecture: Identity, Frame, Coherence Boundary, Drift, and External Correction

The Drift Stack™ Architecture

Identity → Frame → Boundary → Drift → Correction

Recommended Architecture Path

Drift Stack

This is the entry point. It defines the overall framework and the order of the architecture.

This sequence is cumulative. Each layer builds on the one before it.

Start of path

Execution governance before consequence

What the Drift Stack™ Defines

Models generate interpretations, recommendations, plans, and proposed actions. The surrounding architecture determines whether any of those proposals may cross into operational reality.

Drift Stack™ defines the structural conditions required to keep identity, frame, governed state, authority, evidence, admissibility, execution, receipts, and correction coherent as a system changes over time.

The model may propose an action. The architecture decides whether that action is admissible to become real.

Visibility is not execution control

Why Existing Governance Breaks

Policies, monitoring, audit, reporting, explanation, and review improve visibility and accountability. They do not automatically stop an inadmissible action before it executes.

Capability, confidence, prediction, and model reasoning do not create legitimate authority. A consequential system requires an independent authority source and a boundary capable of validating that authority against current state, evidence, policy, constraints, and the exact proposed effect.

Canonical architecture

The Five Drift Stack™ Layers

A1

Identity

Defines what the system is, whose interests and authority it serves, which role is active, and which governing commitments must remain continuous.

A2

Frame

Defines the active reality, objective, jurisdiction, decision context, interpretation, and priority structure in which a proposed action is evaluated.

A3

Coherence Boundary

Defines the governed envelope within which identity, frame, authority, evidence, current state, policy, constraints, admissibility, execution, receipts, and correction must remain mutually valid.

Inside A3

Ledger Layer

The boundary-resident persistence and control layer. It records validated identity, authority, evidence, state, policy, constraints, admissibility decisions, execution grants, receipts, versions, and correction events.

Execution Boundary

The final control point inside the Ledger Layer. It allows, denies, constrains, holds, escalates, or refuses the proposed action before operational consequence binds.

A4

Drift

Measures divergence from declared identity, frame, boundary, ledger state, authority conditions, execution expectations, and governing invariants.

A5

External Correction

Supplies an independent reference capable of challenging the system’s current interpretation, authority, state, execution, or trajectory and forcing governed realignment when drift is detected.

Ledger-resident execution control

What Happens Inside the Coherence Boundary

Authority is externalized from the model’s reasoning and from the executing logic. It may originate in a person, institution, credential, role, delegation, policy, law, or other authoritative source. Once presented for execution, however, that authority is validated, constrained, and bound inside the Coherence Boundary.

The Ledger Layer evaluates the complete SAQ™ Execution Contract and preserves the evidence used in the decision. The Execution Boundary then determines whether the proposed action may cross into operational reality.

Authority Source

Authority is supplied from outside the model’s own reasoning. The system cannot reason itself into permission.

Boundary Validation

Identity, authority, evidence, state, policy, constraints, scope, limits, expiry, and the proposed effect are evaluated together inside the Ledger Layer.

Execution and Receipt

The Execution Boundary issues a bounded decision. The realized result returns as a receipt and becomes evidence for verification, drift detection, and correction.

Authority originates outside the model. Authority validation, admissibility, and execution control occur inside the Coherence Boundary.

Ordered coherence degradation

Universal Failure Sequence

Collapse rarely appears all at once. Identity weakens, frame becomes unstable, boundary conditions erode, drift accumulates, and correction either restores coherence or arrives as external consequence.

Identity → Frame → Coherence Boundary → Drift → External Correction

Authority is not inserted as a sixth top-level layer. Authority is one of the conditions evaluated and bound inside the Coherence Boundary before the Execution Boundary permits action.

From proposal to defensible execution

Governance Architecture Path

1

Execution Is Governed Before It Occurs

A proposal must satisfy the execution contract and pass admissibility before it may change state, invoke a tool, affect a record, move value, or reach the outside world.

2

Authority Is Externalized From Model Reasoning

Capability, confidence, probability, and interpretation do not create permission. Authority must come from an independent source and enter the boundary as a verifiable claim, grant, delegation, role, or policy condition.

3

Authority Is Validated Inside the Boundary

The Ledger Layer checks authority against identity, current state, evidence, policy, scope, limits, constraints, expiry, and the exact proposed effect before execution authority is bound.

4

Interpretation Cannot Become Authority Automatically

Inferred meaning may produce a candidate action. Admissibility determines whether that candidate is permitted to proceed toward the Execution Boundary.

5

Execution Produces a Receipt

The realized outcome returns to the Ledger Layer as evidence of what actually executed, under which grant, against which state, and with which result.

6

Drift Is Measured Against Declared Invariants

Identity, frame, boundary state, ledger evidence, authority conditions, and execution results remain governed reference structures rather than informal expectations.

7

Correction Remains Independent

An external reference can revoke, suspend, compensate, reverse, or realign the system when authoritative reality changes or realized execution diverges from the governed decision.

Canonical standards and specifications

Standards and Specifications

DSS-1 — Drift Substrate Standard

Defines the substrate conditions required to preserve identity, frame, boundary state, governed transitions, and correction across a system that may change over time.

DSS-2 — Sealed Governance Telemetry

Defines the evidence requirements for runtime governance, including structured telemetry, integrity protection, external anchoring, and independent validation.

DSS-3 — Interpretation & Admissibility Control Standard

Separates signal, interpretation, validation, admissibility, and execution so inferred meaning cannot silently become authority.

Invariant Manifold — Formal State and Transition Model

Defines identity, frame, boundary, ledger state, and governed transitions as explicit structures rather than descriptive labels.

Collapse Topology — Ordered Coherence Degradation

Describes how instability propagates as identity, frame, boundary, drift detection, and correction mechanisms weaken.

Architectural Pillars of Execution Governance

Defines externalized authority, pre-execution admissibility, runtime custody and stop-rights, independent validation, and structural impossibility of forbidden actions.

SAQ™ — System Admissibility Qualification

Evaluates whether execution authority is architecturally governable and whether the required mechanisms are present, operating, evidenced, and non-bypassable.

The central principle

The model is not the system.

The system includes the Coherence Boundary, Ledger Layer, authority source, execution contract, admissibility decision, Execution Boundary, bounded executor, receipts, drift detection, and correction path.

Governance binds when the architecture can refuse execution before consequence becomes real.
