gen-platform 0.1.15

gen-platform — Rust-first canonical handle for the typed-dispatcher (typed-tagged-union catamorphism) substrate primitive. Re-exports TypedDispatcher + #[derive(TypedDispatcher)], ships a runtime Dispatcher<T> applicator for Rust consumers (controllers, daemons, reactive routers), and surfaces the typed catalog reflection so any pleme-io crate can stand up a typed dispatch surface against any closed variant universe. The 'common language' substrate primitive — see theory/QUIRK-APPLIER.md.
