Operational Design Domain
Conformance

Autonomy, enforced.

Get Started How It Works

Independent conformance determination. Not a regulator. ODDC does not attest to safety or regulatory compliance.

ENVELO

Enforced Non-Violable Execution-Limit Override — three-tier enforcement from self-correction to hard halt.

The runtime layer that makes boundaries unbreakable

Every autonomous action is validated against declared limits at runtime. Approach triggers self-correction. Breach forces Minimum Risk Condition. Wall contact halts execution.

01
Non-Bypassable
Every action must pass through ENVELO. No backdoors, no overrides, no exceptions.
02
Tiered Enforcement
Approach triggers self-correction. ODD breach forces Minimum Risk Condition. Wall contact halts execution. Three tiers, zero escape.
03
Real-Time
Validation happens at execution time. No stale checks, no delayed enforcement.
04
Tamper-Evident
Every check is logged with cryptographic signatures. Full audit trail.
Deployed by Sentinel as a runtime interlock on your infrastructure — outbound-only, non-bypassable

Zero Trust, Zero Access

Enterprise security teams ask: "Is this interlock a backdoor?" The answer is architecturally impossible.

01
Zero Listening Ports
Interlock opens no inbound ports. Only outbound HTTPS to api.sentinelauthority.org.
02
Customer Controlled
You deploy, configure, and terminate. We cannot start, stop, or modify remotely.
03
TLS 1.3 + Pinning
All communications encrypted with certificate pinning. Data encrypted at rest.
THE CORE GUARANTEE

Sentinel Authority cannot send commands to your system, execute code on your infrastructure, access your network, or control your autonomous systems.

✕ NO REMOTE COMMANDS ✕ NO CODE EXECUTION ✕ NO NETWORK ACCESS ✕ NO ACTUATOR CONTROL
✓ NO PHI/PII ✓ OFFLINE ENFORCEMENT ✓ SOURCE AUDITABLE ✓ HIPAA/BAA

BOUNDARY EXCEEDANCE

Any state, trajectory, or enforcement failure that exceeds attested tolerances — triggers immediate conformance review.

CAT-72

72 hours of continuous operation within declared boundaries. The diagnostic baseline for autonomous system conformance.

01
Continuous Demo
72-hr sustained operation. Systems self-correct near ODD boundary. ENVELO monitors without intervention.
02
Stress Testing
Edge conditions force ODD breaches. ENVELO intervenes — decelerating operations to Minimum Risk Condition before the wall.
03
Enforcement Proof
Verified tiered response: self-correction near ODD, MRC in enforcement margin, hard halt at ENVELO wall.

Enforcement Produces Intelligence

Every conformance cycle maps where a model operates within its declared boundaries — and where it doesn't.

MAP
Violation Mapping
Surfaces the precise conditions where a model exceeds its declared domain.
TREND
Conformance Trending
Longitudinal data showing behavior evolution across certification cycles.
REPORT
Actionable Findings
Specific, reproducible results — not abstract risk scores.
LOOP
Feedback Cycle
Each audit narrows the gap between declared and actual behavior.

Enforcement and improvement are the same operation.
