Modern Act of Know-How: Conductor Quartet — Subject-Isolated Multi-Agent Orchestration for Hallucination-Resistant LLM Processing in Legal and Institutional Environments

Contemporary Large Language Models exhibit a persistent structural defect — contextual contamination, where creative synthesis and rigid factual verification become intermixed within the same probabilistic context, leading to hallucinations in critical infrastructural fields. This document presents a subject-isolated orchestration model: the Conductor Quartet. Four specialised Agent-Subjects (Drinkins, Jimmy, Lin, Sokol) operate without direct communication channels, coordinated solely by a managerial Conductor. The architecture eliminates hallucination propagation, reduces document assembly time from 4–6 hours to 10–15 minutes, and achieves zero errors per 1,000 verifiable fields in legal and institutional documentation. The framework is protected as trade secret under UK Trade Secrets Regulations 2018 and constitutes the core infrastructural know-how of IMARCH LTD / Chronicle OS.
