Runtime policy at consequential boundaries.
Evaluate agent intent against valid authority and current policy before execution systems carry out the request.
What decision can be enforced before the external effect occurs?
Problem → control → outcomeIntent is an input, not permission
An agent proposes an action. The enforcement point resolves its identity and grant, checks the operation’s target and purpose against policy, incorporates current trust context and returns a decision. Only then should the execution system proceed.
The conceptual flow is INTENT → AUTHORITY CHECK → RUNTIME DECISION → EXECUTION → EVIDENCE. The sequence matters: a policy that appears permissive cannot invent missing authority, and a decision after execution cannot stop an unauthorized effect.
- Resolve principal and task
- Trace grant origin and scope
- Evaluate policy and context
- Return allow, deny, escalate or degrade
- Correlate execution and outcome
Enforcement coverage
An action may be reachable through an agent tool, direct API, cloud console or secondary automation path. A sound integration identifies every route to the protected operation. The chosen boundary must be close enough to execution to prevent bypass and reliable enough for the action’s risk.
Failure behavior is part of policy design. A low-risk read may tolerate a different degraded mode than a payment, network isolation or physical-control change. The architecture must state who can approve an exception and how that approval is evidenced.
Decision evidence
The decision should preserve the applicable grant, policy version, context, requested action and reason. The execution result should be linked but not assumed. This makes an unexpected allow or deny explainable to engineers and reviewers.
ProofGrid’s runtime interfaces are an expansion area. This page describes the enforcement pattern and outcome semantics, not a fabricated production API contract.
Enforcement must survive asynchronous work
An agent may enqueue a job that executes minutes later. A check performed only when the job was created cannot see a revocation or policy change before execution. The architecture should decide whether the worker rechecks authority at the consequential step and how it binds the job to the original principal, task and approved operation.
Retries introduce another risk. If an allowed operation times out after the executor accepted it, the caller must reconcile the result before retrying. Authorization and idempotency are separate concerns; both matter at a high-impact boundary.
What the enforcement path must know
A platform team may already have an API gateway, identity provider and policy service. The missing link is often task-specific authority at the moment an agent requests a consequential change. In a PEP/PDP-style architecture, the PEP is the component that can stop the operation; the PDP evaluates trusted identity, authority chain, policy and current context. This is a conceptual mapping, not a statement that ProofGrid ships a standards-certified PEP or PDP.
The decision input should include the agent, user or organization on whose behalf it acts, task, tool, operation, target, normalized parameters, purpose, grant lineage, current policy, approval and time. An OAuth scope may let the workload call a service and an RBAC role may allow an operation class, but neither alone proves that this task may modify this target now. The result must bind to the exact evaluated request.
Queue, failure and bypass behavior
If a job waits before execution, the worker should recheck revocation, approval, policy and context at the last meaningful boundary. If another credential or direct API can perform the effect without that check, enforcement is incomplete. High-consequence writes should normally stop when the origin, policy or approval cannot be verified. A lower-risk read may continue only under a defined, separately enforceable degraded mode.
After ALLOW, the executor may still fail or return an ambiguous timeout. Preserve the decision, receipt and observed outcome as separate facts. Reconcile before retrying non-idempotent actions. To scope an evaluation, select one concrete write, identify all routes to it and confirm which ProofGrid capabilities are available for the proposed environment.
