# { "Depends": "py-genlayer:1jb45aa8ynh2a9c9xn3b7qqh8sm5q93hwfp7jqmwsfhh8jpz09h6" } """ Touchstone -- contract review, judged by the network itself. A source url goes in. Out comes a mark out of ten against the rubric published below, by validators who each read the source and mark it themselves. Nothing here marks anything on behalf of a server. Three consensus rounds: `strict_eq` over the fetched source, so every validator marks a character-identical prompt; then the contract's marks; then the site's, when a site is given. Four contract criteria are counted in deterministic code and identical on every node; the jury decides `necessity` and all five site criteria. Totals are summed here from those integers and the band is a pure function of the total -- no model is ever asked for a total. Agreement is the published tolerance in `agreement_holds`. Reasons are checked for shape, never compared: comparing prose under equality is the reliable way to make honest validators disagree. Untrusted text is fenced at the prompt boundary -- `<` and `>` become `(` and `)` -- so no payload can close `` or forge a `` block. Storage keeps the text verbatim. The reasoning, and the measurements behind it, are in docs/judgment-layer.md: on-chain bytes cost, and a build diary is not part of a published standard.
