The record

Every lens's verdict on every study. buy-below is the only price-falsifiable verdict — scored against the current close. watch / pass / too-hard are recorded but unscored: the question they answer is what would move them, not what to buy.

No buy-below verdict has been issued across 28 studies — 74 watch, 25 pass, 41 too-hard. The checklists have found durable, asset-rich businesses and judged all of them too expensive. An empty buy column is discipline showing its work, not indecision — the reasoning is the product.

Prices are unadjusted TSE closes; as-of dates shown. A price that predates a study's stamp never renders a hit. Corporate actions restate buy-below thresholds at review time.
