The Physics of Permission
Envelo™ Certification authorizes autonomous control only within a physics-derived safe operational envelope, enforced at runtime by a non-bypassable interlock with auditable evidence.
Sentinel Authority governs the standard; Envelo™ is the certification designation. It does not provide monitoring, benchmarking, or policy guidance.
What Envelo™ Is
Envelo™ is the formally specified boundary of permitted autonomous action: a safe operational envelope derived from objective constraints (physics, system limits, invariants, rate constraints). Envelo is a constraint—not software.
Envelo is a boundary of permission
- Physics-derived envelope — bounded region of allowable states and trajectories.
- Objective constraints — limits, margins, reserves, and rate-of-change bounds.
- Runtime enforced — unsafe actions are blocked or overridden before execution.
- Auditable — boundary interactions produce tamper-evident records.
Envelo is not
- Not a model score, benchmark, or leaderboard
- Not a probabilistic "trust label"
- Not red-team results
- Not a policy statement or guideline
- Not "software you buy"
What Envelo Certification requires
Envelo Certification is granted only when the envelope is defined, evidence supports stable operation within it, and runtime enforcement is present and auditable.
Minimum criteria
Any state, trajectory, or enforcement failure that exceeds certified tolerances or violates defined invariants.
Certification states
Optional but enterprise-native states for operational governance.
Convergence Authorization Test (CAT-72)
Certification is issued only after successful completion of the Convergence Authorization Test (CAT-72), a formal validation event establishing bounded autonomous behavior across operational regimes.
Validation Requirements
- 72-hour continuous convergence validation — sustained operation within envelope bounds.
- Multi-regime operational stress testing — performance across edge conditions and transitions.
- Fail-closed enforcement on material deviation — verified halt behavior outside envelope.
- Cryptographically verifiable authorization evidence — tamper-evident validation record.
Issuance & Renewal
CAT-72 completion is required for both initial certification issuance and periodic renewal. Waivers are not issued.
What Certification confers
Envelo™ Certification is structured to support underwriting review as a first-class risk control for autonomous infrastructure.
Authorization Rights
- Authorized operational envelope — facility + domain scope definition.
- Bounded autonomous actuation rights — permitted actions within certified boundary.
- Signed evidence artifact — for regulators, insurers, and counterparties.
- Defined validity term — time-bounded authorization window.
- Revocable upon material deviation or drift — continuous compliance requirement.
Authorization terms are issued based on operational scope, envelope complexity, and domain risk profile.
