1. Abstract
The Vertical AI Governance Stack is a vendor-neutral reference architecture for converting:
normative obligations → semantic policy → delegated authority → controlled execution → verifiable evidence → resilient operation
The Stack remains independent of LLM vendors, cloud providers, and agent frameworks. Its concern is governance architecture, not model selection.
2. Foundational Thesis
Models may change. Operational knowledge must remain sovereign.
Probabilistic intelligence must never be allowed to override deterministic authority.
Probabilistic intelligence may propose, reason and plan. Deterministic governance defines what may become real.
3. The Invariant Matrix (L1–L6)
The core architecture establishes six non-negotiable layer invariants:
| Layer | Governs | Canonical Invariant |
|---|---|---|
| L1 | Authority | Models may interpret governance. They must not constitute governance. |
| L2 | Meaning | The meaning of the business must not depend on the model interpreting it. |
| L3 | Authority Delegation | Intelligence defines possibility. Governance defines authority. |
| L4 | Execution Boundary | Authorization is not execution. Every authorized intent must pass through a controlled execution boundary. |
| L5 | Evidence Ledger | Trust requires reconstructibility. |
| L6 | Failure & Fallback | When assurance decreases, autonomy must decrease with it. |
4. Governance Proof Obligations
For every material governed operation, an implementation MUST be able to demonstrate:
Why was this action permissible?
Demonstrable capability decision binding caller claims to explicit operational rules.
Who or what requested it?
Cryptographically authenticated principal identity (human, service, agent, daemon).
Was the requested resource inside authorized boundaries?
Strict tenant and resource isolation check independent of client inputs.
Did actual execution correspond to authorized execution?
Parameter immutability and capability hash verification post-authorization.
Which verified facts supported the decision?
Verifiable execution audit records linking inputs, models, rules, and outcomes.
What state change actually occurred?
Deterministic execution side-effect confirmation.
What happens when this operation fails?
Graceful fallback to lower autonomy tiers or human intervention.
5. Governance Pipeline
All operational execution paths must flow through aCapability Verification Adapter (CVA):
No model output or API call may bypass the CVA. Unverified execution attempts must be rejected at the boundary and logged as security coverage gaps.
