@thecontinuitylab/myshape

Motion-signature verification for continuity proofs. CPS-0001 compatible.

Reference implementation of the MyShape motion-signature engine. Sensor data in → verification result out. Research by The Continuity Lab.

Install

npm install @thecontinuitylab/myshape

Quick Test

import { verifyContinuity } from "@thecontinuitylab/myshape";

const result = await verifyContinuity({
  imuSamples: [],       // required — IMU sensor samples (EE-002)
  cameraSamples: [],    // optional — camera motion (EE-002 cross-modal)
  frames: [],           // optional — pose frames (EE-001 PES)
  timestamps: [],       // optional — pose frame timestamps (EE-001)
  challengeResults: [], // optional — challenge rounds (EE-003)
});

// → { verdict, confidence, evidence, threatReport }

verifyContinuity implements CPS-0001 v0.2 two-stage verification: Stage 1 = EE-001 ≥ 0.50 (Presence Entropy Score); Stage 2 = EE-003 = 1.0 (all 3 challenge rounds pass); both must pass. Confidence is the weaker stage (min). EE-002 (Cross-Modal Causal Coupling) is informational only and does not affect the verdict.

CPS-0001 Receipts

For engine-independent continuity receipts, the package also exports the CPS-0001 layer — buildReceipt, signReceipt, verifyReceipt, generateKeyPair, plus full schema checks (verifySchema, verifyAssertions, verifyTemporal, verifyFreshness). Receipts are Ed25519-signed and interoperable across implementations.
