Who writes this, how it is checked, and how it changes

This manual is written and maintained by MarketComp. Every factual claim that can go stale carries a source in its section's reference list, maturity fields state evidence rather than adjectives, and comparison tables describe structural properties and cost profiles of a design rather than benchmark numbers, which depend on hardware and circuit shape and rot within months; where live benchmarks exist the tables say where, and who maintains each implementation. Each page names its author, its last-updated date and the version it belongs to, so a citation can point at exactly what was said and when. Where a second reviewer has checked a page, the byline says so; where none has, it does not pretend otherwise.
