 Semantic editor integration lives in the host-configurable language service crate.
 It depends only on the runtime and accepts the same `HostEnvironment` implementation used by a production application.
-A host-specific LSP binary can link this crate with its loader and global schema configuration without reimplementing evaluation rules.
+The LSP crate adapts that service to the Language Server Protocol over stdin/stdout.
+It provides full document synchronization, semantic diagnostics, and whole-document formatting.

+The default `decodal-lsp` binary reads Decodal imports from the filesystem.
+Embedded hosts can call its library entry point with a custom `LspEnvironment` to reuse structured imports and to make unsaved external documents, such as Markdown, visible to the loader.

 Source formatting lives in a separate Rust language tools crate.
 Keeping it separate prevents host-specific semantic services from inheriting the formatter's Tree-sitter and WebAssembly dependencies.
