Logos Lexicon
Bounded intent tokens for policy resolution
Logos Lexicon is the advanced layer after VINAC-FM proves the physical authorization path. It gives policies a compact vocabulary for what an agent wants to do without passing arbitrary instructions.
Four Foundational Principles
Logos Lexicon is not a command language. It is a compact vocabulary of pre-agreed semantic tokens resolved locally without instruction parsing.
Bounded Intent, Not Instructions
Agents transmit compact intent references. The receiving system resolves meaning locally from a versioned logic library.
Transport-Agnostic
The same state-frame 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.
The Semantic Coordination Stack
Logos Lexicon sits between cloud policy and local execution. The transport proves delivery or presence; Logos defines meaning.

How It Works
From policy-bound intent to deterministic local resolution
State-Frame Token Generation
Vocabulary version, intent ID, context bits, parameter indexes, and nonce or session references become a compact state frame.
Transport Validation
VINAC-FM, NFC, QR, optical, wired, or network transport supplies delivery and proof metadata. The token itself stays transport-independent.
Local Logic Library Resolution
The receiving machine maps the token to a pre-approved handler and enforces context, parameter ranges, risk level, required authorization, and audit labels.

Integration Example
Token Generation: Agent A
import { LogosLexicon } from '@silentauth/logos-lexicon';
const lexicon = new LogosLexicon({
publicKey: 'pk_live_…',
version: '2.0.0',
});
// Generate a state-frame token for a pre-approved action
const token = await lexicon.generate({
intent: 'LL_EXEC_001',
context: {
session_id: 'sess_abc123',
agent_id: 'agent_local',
timestamp: Date.now(),
},
parameters: {
action_hash: 'sha256:...',
policy_hash: 'sha256:...',
},
});
// token.id -> 'LL_EXEC_001'
// token.state_frame -> compact bounded reference
// token.version -> '2.0.0'Policy Resolution: Agent B (Receiver)
import { LogosLexicon } from '@silentauth/logos-lexicon';
const lexicon = new LogosLexicon({
publicKey: 'pk_live_…',
version: '2.0.0',
});
// Resolve incoming token against local logic library
const result = await lexicon.resolve(receivedToken);
if (result.allowed) {
console.log(result.action);
// {
// label: 'authorize_agent_action',
// namespace: 'agent.execution',
// required_layer: 4,
// risk_tier: 'high',
// execution_policy: {
// max_uses: 1,
// rate_limit_per_hour: 20,
// approval_window_seconds: 300
// }
// }
}Policy Evaluation: standalone, no network required
import { evaluatePolicy } from '@silentauth/logos-lexicon';
// Evaluate offline, logic library is locally bundled
const decision = evaluatePolicy({
token_id: 'LL_APPROVE_001',
context: { action_hash: 'sha256:...', vinac_level: 3 },
});
// { allowed: true, required_presence: 'VINAC_FM_LEVEL_3' }Use Cases
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.

Included In Open Preview
Logos Lexicon is part of the shared SilentAuth preview workspace. Pricing tiers are intentionally disabled while the vocabulary, VINAC-FM binding, and local gateway path are validated.
The grammar of machine coordination
Stop passing instructions. Start exchanging pre-agreed intent references that resolve locally under versioned policy.
