PROMETHEAN ECOSYSTEM
Sovereign Data Storage Layer

DEPTHOS BRIDGE.

The local-first hardware storage and identity bridge. DepthOS secures private keys, manages Promethean Passport credentials, and controls offline mesh replication to defend citizens against centralized data exploitation.

Local-First Vault Architecture

Keys, credentials, and SSI passport data are locked locally using AES-GCM-256 in sandboxed hardware layers, completely isolated from browser memory.

P2P Mesh Synchronization

Direct, encrypted sync pipelines bridge local mutations safely with the global Sovereign Mesh, preserving absolute local data custody.

Zero-Knowledge SSI Auth

Generate and present cryptographically secure verifiable credentials (VCs) without revealing underlying private keys or personal metadata.

Visual-Symbolic Synthesis

Couples continuous 2D/3D visual coordinate mathematics with symbolic DOM code, allowing local agents to mathematically 'see' client interactions, saliency maps, and rendering states.

Cross-Device Warm Migration

Through safe, local RPC bridges, developers can instantly share secure states and active credentials across multiple local devices without cloud storage.

Storage Bridging

NPM Package (Client SDK)
npm install @promethean/depthos-bridge
Peer Dependencies
npm install @promethean/mesh-daemon
Isolated Vault Enclave Bridge
npx depthos-enclave-bridge init
Always run DepthOS Bridge inside sandboxed local environments. Never stream unencrypted vault payloads onto remote backends.

Vault Authentication Quick Start

import { DepthOS } from '@promethean/depthos-bridge';

// Initialize isolated local secure storage client
const store = new DepthOS({
  mode: 'local-first',
  sync: 'mesh',
  vaultOptions: {
    enclaveSandbox: true,
    autoLockTimerMs: 300000 // 5 minutes
  }
});

async function secureCredentials() {
  try {
    console.log('Unlocking local secure hardware enclave...');
    await store.vault.unlock(process.env.PASSPORT_PIN);
    
    console.log('Retrieving dynamic cryptographic credentials...');
    const credentials = await store.vault.read('dynamic_credentials');
    
    // Decrypt credentials locally using hardware keys
    const decodedDID = await store.identity.verifyDID(credentials.didToken);
    
    console.log('Sovereign data decrypted locally inside Enclave.');
    console.log('Owner DID:', decodedDID.subject);
    
    // Automatically lock vault memory after usage
    await store.vault.lock();
  } catch (err) {
    console.error('Local-first hardware vault unlock rejected:', err.message);
  }
}

secureCredentials();

SVSS Sensory Telemetry Quick Start

import { SVSS } from '@promethean/depthos-bridge';

// Initialize the local-first Visual-Symbolic sensory engine
const svss = new SVSS({
  viewportMode: 'hybrid-3d', // Supports 2D DOM and 3D WebGL camera projection
  mcpServer: {
    enabled: true,
    port: 4009 // Expose Model Context Protocol endpoint for local agents
  }
});

// Stream real-time visual saliency maps and trajectory vectors
svss.on('telemetry', ({ saliencyMap, userTrajectory }) => {
  console.log('Saliency Peaks (Attention):', saliencyMap.peaks);
  console.log('Human Cursor Velocity Vector:', userTrajectory.velocity);
});

// Let local agents resolve visual collisions via Model Context Protocol
svss.on('mcp:resolve_collision', async (event) => {
  console.log('Agent requesting visual overlap mitigation...');
  const newStyles = await computeOptimalConstraints(event.box);
  await svss.applyStyles(event.targetId, newStyles);
});
Standardized Protocol Support

Conversational Pivot Protocol (CPP)

DepthOS Bridge natively integrates the Conversational Pivot Protocol. Securely cache the Directed Semantic Graph (DSG) structure locally, enforce zero-knowledge authentication on conversation nodes, and manage hot-halting and splicing on client-side dialogue streams using the official CPP Integration Pack.
