These scores express our judgement of the cited product facts. They are not measured performance benchmarks. Each product is assessed for its stated purpose; a higher score does not make different workflows interchangeable.
Evidence gaps lower confidence and affect the relevant judgement. Unknown pricing does not mean free access. Research prototypes and retired products retain their historical scope, with adoption ratings reflecting current access.
