Early Experiment / Work in Progress. Numbers are mechanically derived from surface introspection and, for eval-capable dialects, behavior parity against Clojure (JVM). They are not formal parity claims for any dialect. Dialects target different platforms with different goals, so not every part of Clojure's surface is in scope for every dialect. A lower implementation percentage reflects scope, not maturity, quality, or usefulness. The data is intended for dialect maintainers and for engineers porting Clojure code across runtimes.
