How Runtime AI Governance Works: Pre-Execution AI Policy Enforcement

1. AI Request — what initiated the action?

Runtime governance begins at intake. The control plane must know that an AI-bound action exists and which pathway it uses. Requests arrive through many surfaces:

• End-user interaction in an application
• Backend application or microservice call
• Autonomous AI agent proposing its next step
• Multi-step workflow orchestration
• Direct API integration
• Tool or function invocation inside an agent loop

2. Identity — who or what is acting?

Identity is not only the human behind a keyboard. Agents, service accounts, delegated roles, and cross-application impersonation all require binding before policy can apply correctly.

• Who or what initiated the action?
• Which agent instance, if any?
• Which application or workload class?
• Which organization and tenant scope?
• What permissions and roles are effective for this request?

3. Intent — what is the AI attempting to do?

Intent classification separates radically different governance decisions. Generating marketing copy, retrieving customer records, and initiating a funds transfer may all involve an LLM—but they carry different risk, data sensitivity, and authority requirements.

Runtime governance evaluates intent explicitly rather than treating all model output as equivalent. Intent may be declared by the caller, inferred from tool selection, or derived from structured action metadata— but it must be bound before policy runs.

• Generate or transform content
• Retrieve or summarize regulated data
• Invoke an external tool or API
• Execute a financial or operational transaction
• Delegate to another agent or sub-workflow

4. Policy Evaluation — allow, constrain, escalate, or deny

Policy evaluation is one of the strongest concrete signals of runtime control. The control plane evaluates the action against organizational governance policy and returns a deterministic outcome—not a post-hoc annotation.

• ALLOW — proceed on the governed path under current constraints
• MASK — permit with sensitive fields or segments masked
• REDACT — remove or replace disallowed content before continuation
• REQUIRE_APPROVAL — pause until human authority clears the action
• QUARANTINE — isolate the request or output for review without execution
• BLOCK — deny execution; fail closed when policy or inputs are insufficient

5. Boundary Check — data and trust-boundary enforcement

Boundary checks determine whether the AI is permitted to access or transmit the requested data on this path. This connects directly to AI Boundary Protection: constraining what crosses AI pathways under policy, not only detecting leakage after the fact.

Boundary enforcement complements identity and intent. A caller may be authenticated and authorized for summarization while still prohibited from exporting raw PII to an external model provider.

• Source data classification and residency rules
• Cross-border or cross-segment transmission constraints
• Provider and model allowlists tied to data sensitivity
• Retrieval scope limits for RAG and tool-backed access

6. Human Authority Gate — when autonomy must stop

Some actions should not execute autonomously regardless of model confidence. Human Authority Gates insert accountable human decision points into the execution lifecycle—particularly in regulated environments.

• AI proposes an action based on reasoning or tool selection
• CGOS (or the governing control plane) evaluates policy and risk
• Human approval is required when policy demands it
• A human authorizes, denies, or overrides with recorded justification
• Execution proceeds only after the authority gate clears

7. Authorization — proposal is not permission

A critical governance distinction: an AI system can generate or propose an action without being authorized to execute it. Authorization is an explicit governance decision—distinct from model output, tool availability, or prior session context.

Runtime governance records who or what authorized execution, under which policy version, and with what constraints. This separation is essential for audit, replay, and supervisory review.

8. Execution — governed paths only

Execution occurs only after identity, intent, policy, boundary, authority, and authorization requirements are satisfied. Ungoverned direct calls to models or tools represent side channels that bypass the control plane.

On approved paths, execution routes to permitted providers, tools, and downstream systems. Consumption and usage constraints may apply in parallel with boundary rules.

9. Evidence — TAP and immutable audit lineage

Every important governance decision should produce evidence suitable for operators, assurance teams, and—where applicable—regulators. Evidence is part of the architecture, not an optional logging add-on.

• TAP (Trace, Audit, Proof) and governance evidence records
• Policy decision lineage: inputs, outcome, and rationale signals
• Authorization and human approval attribution
• Execution outcome and downstream correlation identifiers
• Governance replay for investigation and audit reconstruction

• Per-step enforcement—not one-time prompt approval at session start
• Tool-level policy for APIs, databases, financial systems, and internal services
• Human authority gates on high-impact tool calls within agent loops
• Trajectory evidence linking reasoning steps to executed actions

• AI Gateway-oriented intake for governed AI-bound requests
• Governance policy engine with deterministic adjudication outcomes
• AI Boundary Engine and AI Consumption Engine under policy
• Human Authority Gate for elevated-risk and irreversible actions
• Approved provider routing—execution only on permitted paths
• TAP evidence, Governance Replay, and Runtime Intelligence for operators
