How this receipt has changed

Light-like curves in general relativity are not necessarily geodesics

Published on 06 Aug 2026, now at version 2. Each rewrite keeps the version it replaced, with the reason and the engine that wrote it.

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.
