This receipt has not been rewritten since it was published on 04 Aug 2026. Its current version is 1.
Weight is the one the receipt's balance bar uses: every source counts 1, plus a bounded bonus for how often it has been cited, so one famous paper cannot outweigh three dissenting ones (at most 3x a bare source). It is a reading aid built from facts the receipt already stores, not the engine's confidence.
