01
Exact-action binding
Bind approved intent and authority to the target and parameters that are actually presented for execution.
ACTION SECURITY FOR AI SYSTEMS
Authorization is a decision.
Security must survive the action.
APC binds the governing security contract to the exact act, validates security-relevant transitions, and checks enforcement at the protected side-effect boundary.
Action-bound security Transition validation Verifiable run evidence
THE SECURITY PATH
From decision to effect.
Without losing the contract.
APC sits across the action path. It does not replace your identity provider, policy decision point, agent framework, or infrastructure.

APC
The decision is not the action. APC preserves the relationship between the decision, the exact act, its authority and the effect boundary across security-relevant transitions.
WHAT APC GOVERNS
Control the path, not just the policy check.
02
Transition integrity
Validate security requirements as actions move through agents, tools, integrations and providers.
03
Authority lifecycle
Apply freshness, expiry, replay, concurrency and delegation constraints to action authority.
04
Finality enforcement
Re-check the governing contract at the protected executor boundary before a sensitive effect.
05
Evidence & reconciliation
Record structured decision and run evidence; handle uncertain provider outcomes as a reconciliation problem.
06
Integration boundary
Work alongside customer identity, PDPs, agent frameworks and provider systems without claiming ownership of them.
DEVELOPER WORKSPACE
Inspect the decision.
Change the input. Break the assumptions.
Write and run a policy expression, mutate an action, test hostile conditions and export the resulting run record.

IMPLEMENTATION BOUNDARY
Clear scope. Inspectable output.
The public playground runs locally in your browser using synthetic inputs. It does not call external providers or execute real-world actions. Exported records describe the run performed by the playground; they are not independent certification or proof of a production control.
Production deployment requires the relevant customer identity, policy, provider, egress, finality and reconciliation integrations to be implemented and verified for the action class.
