Logos Lexicon

Bounded Intent, Not Instructions

Agents transmit compact intent references. The receiving system resolves meaning locally from a versioned logic library.

Transport-Agnostic

The same signed intent token model can ride over VINAC-FM, optical, UWB, NFC, wired local buses, or conventional network transport.

Policy Before Execution

Every token is checked against version, context, parameter bounds, nonce or session reference, authorization level, and local policy.

Local Logic Libraries

Logic libraries are pre-agreed and locally stored. No remote code execution. No prompt parsing. Meaning is deterministic and auditable.

Vocabulary and signed token

import { compileLogos, LogosLexicon } from '@silentauth/logos-lexicon';

const { vocabulary } = compileLogos(`
  vocabulary silentauth.agent.v1

  intent CSIV_EXEC_001 agent.execute {
    risk: 4
    context: ai_agent_runtime
    params: agentId, toolName, actionHash
    proofs: human_approval, vinac_fm_level_3
    handler: agents.execute
  }
`);

const lexicon = new LogosLexicon();
lexicon.registerVocabulary(vocabulary);

const token = lexicon.createToken({
  vocabularyVersion: 'silentauth.agent.v1',
  intent: 'agent.execute',
  context: 'ai_agent_runtime',
  params: {
    agentId: 'agent_local',
    toolName: 'deploy_service',
    actionHash: 'sha256:...'
  },
  nonce: 'fresh-nonce'
});

const signed = await lexicon.sign(token, {
  keyId: 'server-key-1',
  secret: process.env.LOGOS_HS256_SECRET!
});

Verify and resolve before dispatch

const result = await lexicon.verifyAndResolve(signed, {
  secret: process.env.LOGOS_HS256_SECRET!,
  resolution: {
    context: 'ai_agent_runtime',
    satisfiedProofs: [
      'human_approval',
      'vinac_fm_level_3'
    ]
  }
});

if (!result.ok) {
  throw new Error(`Logos denied: ${result.reason}`);
}

await handlers[result.resolved.handler](result.token.params);

AI Agent Pipelines

Replace natural language instruction passing between agents with typed semantic tokens. Every action is pre-agreed, bounded, and auditable, with no prompt injection path.

Cross-System Automation

Coordinate microservices, IoT devices, and ML models with a common semantic vocabulary. A token emitted by a sensor is resolved identically in cloud infrastructure.

Physical-Digital Bridging

Bind digital actions to physical presence using VINAC-FM as the transport. The Logos Lexicon token carries the semantic intent; the acoustic channel proves it is legitimate.

Zero-Trust M2M Auth

Remove implicit trust from machine-to-machine calls. Every action is an explicit token resolved against a pre-shared, locally-auditable logic library.
