Ternary Logic (TL) System Architecture: Implementation Guide for Dual-Lane Latency

This technical note specifies the Dual-Lane Latency architecture for implementing Ternary Logic (TL) in high-throughput financial environments. Current Anti-Money Laundering (AML) systems suffer from an "Interdiction Gap" because rigorous compliance checks introduce unacceptable latency into real-time payment rails. This specification resolves that conflict by decoupling State Determination from Evidentiary Anchoring. The architecture defines two distinct processing lanes: Fast Lane (≤2ms): Performs synchronous state verification (+1 Proceed, 0 Epistemic Hold, -1 Refuse) and initiates the Decision Log header. This ensures governance precedes economic action. Slow Lane (≤500ms): Performs asynchronous cryptographic sealing and Merkle-Batched Anchoring. This allows for O(1) verification complexity per batch, ensuring long-term evidentiary permanence without blocking transaction settlement. This guide details the technical specifications for the "No Log = No Action" protocol, the integration of Verifiable Delay Functions (VDFs) for handling ambiguity under load, and the semantic mapping of TL states to ISO 20022 payment messages.
