How this receipt has changed

Forward scattering is equivalent to no scattering.

This receipt has not been rewritten since it was published on 05 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.
