Human Validation Layer: Constitutional Coherence Through Human-Governed Refinement

Large language models and automated decomposition systems can scaffold, decompose, index, and draft semantic structures at a scale that unaided review cannot match. Scale, however, does not establish fidelity, admissibility, authority, evidence, or global coherence. This paper proposes the Human Validation Layer (HVL) as a governed review and adjudication surface for deciding whether machine-generated or machine-assisted semantic artifacts may be promoted toward binding state. HVL is neither an assertion that humans are infallible nor a synonym for proofreading. It is a protocol in which accountable reviewers inspect typed artifacts, preserve source custody, record findings, surface disagreement, and either promote, hold, revise, split, merge, escalate, contest, or refuse. Condexing names the preparation of Pre-Crystallized Material (PCM) into non-binding Context Index (CONDEX) artifacts. A Condexer prepares reviewable evidence candidates; only an actor or procedure with the required authority may admit or bind them. The core claim is deliberately bounded: human participation can provide an accountable promotion boundary when its jurisdiction, evidence, criteria, conflicts, reasons, and authority are explicit and receipted. Human presence alone establishes none of those properties. The paper defines validation objects, role separation, promotion policy, failure modes, evaluation requirements, and interfaces with the Governed Meaning Base (GMB), Governed Context and Memory, semantic custody, governed semantic compilation, lexical and structural binding, authority-laundering tests, and reasoning by way of receipts.
