MGOS Runtime Stack

Deterministic authorization
between AI proposals and
real-world execution.

The complete runtime path — from uncertain upstream input to deterministic downstream execution control. One product. One boundary. Verifiable evidence trail.

AI proposes. Integrity stabilizes. MGOS authorizes. Evidence proves.

The problem

Models generate proposals.
Sensors generate observations.
Neither should control execution.

Current guardrails are probabilistic, model-internal, and unauditable. Between proposal and execution, the authorization boundary is often fragmented, implicit, or unverifiable.

AI / SENSORS ? EXECUTION LAYER
Imagine a factory

A robot gets orders
from an AI.

The AI is brilliant — it plans, optimizes, learns. But it also hallucinates, contradicts itself, and has no concept of consequence. Between the proposal and the robot arm, you need something that never guesses.

Layer 1 — Integrity Engine

Quality inspector
at the gate.

Data arrives from everywhere — sensors, models, databases. The Integrity Engine doesn't decide. It asks one question: can these inputs be stabilized without collapsing genuine conflict into false consistency?

If two sensors disagree, it preserves the conflict as a signal. Only a stabilized state moves downstream.

Layer 2 — Decision Kernel

The guard at
the boundary.

It receives the stabilized state and answers exactly one question: is execution allowed?

Three outcomes. No fourth option. No "maybe." No inference. The same stabilized state under the same policy always produces the same result.

LEAN 4 Core decision logic formally verified. Proved properties: fail-safe authorization, conflict safety, output exhaustiveness, permutation invariance (TMR), manual-override dominance.

Layer 3 — Evidence

The notary.

Every decision produces a cryptographic receipt. SHA-256 hash, manifest, timestamp. Cryptographically verifiable. Tamper-evident. If someone asks in a year why the robot stopped — the receipt and evidence trail exist.

Layer 4 — Sentinel Console

The dashboard.

The human operator sees everything. Every decision, every conflict, every receipt.

Run tests. Inspect decisions. Export evidence. A runtime without operator visibility is operational risk.

What is proved. What is engineered. What is operational.

Verified scope.

Formally verified

Core authorization logic proved in Lean 4:

Fail-safe authorization
Conflict safety
Output exhaustiveness
Permutation invariance (TMR)
Manual-override dominance
Formal methods paper and artifact available on request
Engineered

Implementation layer:

Integrity pipeline
Normalizer boundary (N1–N3)
Evidence receipts + manifests
Sentinel operator console
SHA-256 evidence bundles
Refinement obligations explicit. Core formal proofs begin after the normalization boundary. Normalizer verification (PO4) remains open.
Operationally validated

Black-box test suites:

Baseline hardtests: PASS
Soak tests: PASS
Poison-input tests: PASS
Zero unsafe authorization
Fail-close coverage = 1.0
In audited suites. Determinism and receipt identity claimed within pinned environment; cross-platform bitwise identity is out of scope.
Core principles
01
We don't force data consistency.
02
Conflict is signal, not noise.
03
Only stabilized state reaches the decision.
04
Execution is deterministic and fail-safe.
