Knowledge Units for Multi-Model Deliberation

This document defines the Knowledge Unit (KU) format for representing verified knowledge produced through structured multi-model deliberation. A Knowledge Unit captures the question asked, the models that participated, the consensus achieved, the points of agreement and disagreement, and the cryptographic receipts that bind each deliberation round to an independently verifiable chain. The format addresses the epistemic integrity gap in LLM-maintained knowledge bases: how to prove that knowledge was derived through a rigorous process, that disagreement was preserved rather than smoothed away, and that the record has not been tampered with. This specification complements draft-farley-acta-signed-receipts, which defines the receipt format and verification protocol used to sign individual deliberation rounds.
