Deterministic Physical Presence Verification SDK for Real-Time Systems

SAREI Kernel provides a lightweight client SDK to capture ephemeral physical signals and submit them for deterministic presence verification by SAREI Sovereign Infrastructure.

This package is intentionally minimal. All sovereign logic, decision-making, and enforcement reside on SAREI servers.

What SAREI Kernel Does

• Captures short-lived physical interaction signals (e.g. micro-latency, entropy variance).
• Submits those signals to SAREI’s verification API.
• Returns a presence coherence state, not a score.

Core Principle

Presence is a physical property. Identity is a social construct. SAREI evaluates physical coherence, not identity, intent, or behavior.

What SAREI Kernel Is Not

SAREI Kernel does not:

• Identify users
• Track individuals across sessions
• Generate behavioral profiles
• Store persistent fingerprints
• Make security or business decisions

The SDK is telemetry-only.

Installation

npm install @sarei/kernel

Conceptual Usage

import { Kernel } from "@sarei/kernel";

// 1. Initialize (Client-Side)
Kernel.init({ apiKey: "pk_live_..." });

// 2. Verify Presence
const result = await Kernel.verify(trace, "checkout");

if (result.verified) {
  // Presence is physically coherent
} else {
  // Sovereign Veto (Fail-Secure)
  console.error("Veto Reason:", result.reason);
}

Returned states are categorical, not probabilistic.

Fail-Secure Principle

GUAW follows a fail-secure doctrine:

• Incoherence → denial
• Insufficient signal → silence
• System corruption → termination
• Expired License → Hard Stop (402 Payment Required)

Integrity is prioritized over availability. If a contract or evaluation period ends, the sovereign shield closes instantly.

Responsibility Boundary

• GUAW does not act.
• GUAW does not decide.

All final decisions remain the responsibility of the integrating system.

Cryptography & Sovereign Integrity

Future-Proof Defense

• Current Standard: RSA-4096 for signed audit proofs.
• Near-Term Evolution: Post-Quantum Ready Signatures (Ed25519).
  • Status: Prototyping in GUAW internal labs.
  • Purpose: Ensuring deterministic presence verification remains resilient against future quantum threats.

Licensing & Evaluation

This SDK is released under a Proprietary / Evaluation License.

• Free for evaluation (7 Days).
• Service terminates immediately upon evaluation expiry (Hard Stop).
• Enterprise usage requires a contractual agreement.
• Reverse engineering and signal extraction are prohibited.
