Authority Verification Runtime
The Authority Verification Runtime is the enforcement layer that ensures only valid Authorization Decisions are executed. It is the final gate before real-world execution.System Flow
Authorization Decision → Authority Verification Runtime → Execution Runtime → Attestation
1. Input: Authorization Decision
The runtime receives an Authorization Decision from Governance.
This decision is:
deterministic
policy-bound
cryptographically traceable
No raw AI input is accepted at this stage.
2. Authority verification
The runtime verifies:
policy version consistency
signal hash integrity
executionId uniqueness
decision authenticity
If any check fails, execution is rejected.
3. Enforcement rules
The runtime enforces strict rules:
no unauthorized execution
no replayed decisions
no modified decision payloads
no external override without explicit authorization
4. Execution gating
Only verified Authorization Decisions are allowed to proceed to execution.
The runtime acts as a hard gate:
VALID → execution allowed
INVALID → execution blocked
5. Deterministic enforcement
The runtime is fully deterministic:
same decision → same enforcement outcome
no runtime randomness
no external influence
6. Failure behavior
If verification cannot be completed:
→ execution is rejected (fail-closed)
There is no fallback mode.
Properties of Authority Verification Runtime
Hard enforcement boundary
No execution can bypass this layer.
Deterministic validation
All decisions are verified consistently.
Replay protection
Duplicate or reused decisions are rejected.
Cryptographic trust
All decisions are validated using signatures.
Summary
The Authority Verification Runtime ensures that:
only valid Authorization Decisions are executed
no tampering occurs after governance evaluation
execution is strictly gated and deterministic
system integrity is enforced at runtime boundary
