The valuation core from a production asset-marketplace platform, with its real constants: formula lenses turn evidence into a value center, comparable sales fold in weighted by source trust × similarity, and the blend becomes a hard anchor band the AI can only narrate inside — a deterministic clamp re-applies after it, regardless.
ARR × growth-adjusted multiple: multiple ×4.40 → lens center $898k
An escrow-confirmed sale carries double the weight of a scraped listing. Change a source and watch the anchor move.
Weighted comp average $788k · blended into the anchor at 60% (scales with evidence mass)
Early versions let the model see raw financials and abstract scores — it would confidently invent prices. That is a live model above, asked the same question each run, and its answer moves every time. The fix: the AI never sets the number. And a companion rule keeps the pipeline honest: every metric is tagged value, risk, or confidence, so connecting more tools can corroborate a valuation but never inflate it.
