 ## crates.io release
 
 The primary crates.io package is `decodal`, which contains the embeddable library.
-`decodal-derive` provides optional derive macros for Rust struct integration.
-Workspace support crates such as `decodal-cli` and `decodal-wasm` are not published for 0.1.0.
+`decodal-derive` provides optional derive macros for Rust struct integration and is published only when the derive crate changes.
+Workspace support crates such as `decodal-cli` and the Rust source crate `decodal-wasm` are not published to crates.io.
+The generated WebAssembly package under `site/decodal-site/src/wasm/` is published to npm and JSR.

 The playground editor uses CodeMirror 6 with the generated Lezer parser in `src/lib/codemirror/decodal-parser.js`.
 The canonical grammar is documented in `doc/manual/souce/language/grammar.md`; regenerate the Lezer parser when that grammar or `editors/lezer-decodal/decodal.grammar` changes.
 The documentation build still uses the lightweight JavaScript fallback highlighter so Astro can render Markdown without initializing WASM at build time.
