📈 Impact on SCBE-AETHERMOORE

Enhanced Security

Topological Intrusion Detection - New layer of defense
Graph-Theoretic Security - Mathematically provable properties
Cryptographic Chaining - 256-bit HMAC-SHA256 strength
Multi-Attack Detection - Deviation, skip, curvature attacks

Integration Points

PHDM integrates seamlessly with existing SCBE layers:

Layer 5 - Hyperbolic metric for distance computation
Layer 8 - Multi-well potential for polyhedron selection
Layer 11 - Triadic consensus for path validation
Layer 12 - Harmonic scaling for risk amplification
Layer 13 - Decision gate for intrusion response

Developer Experience

// Simple API
import { PolyhedralHamiltonianDefenseManifold } from '@scbe/aethermoore/harmonic';

const phdm = new PolyhedralHamiltonianDefenseManifold();
const keys = phdm.initialize(masterKey);
const result = phdm.monitor(state, time);

console.log(`Intrusion: ${result.isIntrusion}`);
console.log(`Rhythm: ${result.rhythmPattern}`);
