 `:lsp_definition` or the configured Space d binding requests a definition at the primary caret, once regardless of selection count. Both Location and LocationLink results are supported; multiple results use the first. Local-file navigation reuses loaded buffers without overwriting unsaved text. LSP UTF-16 positions and percent-encoded file URIs are translated to validated grapheme coordinates. Navigation is ignored if its source buffer, revision, caret, or latest request has changed.
 
+For programmatic bindings, use `config.core.lsp_definition` and `config.core.lsp_diagnostics`, immutable Action objects eligible in Normal mode. Both route to the same native implementation as their Ex commands; no LSP keys are bound by default. These actions are also available in the command palette.

 Diagnostics appear as severity-colored gutter numbers and text underlines; the primary caret's diagnostic appears in the message row. `:lsp_diagnostics` reports the current document's server state. Older versioned diagnostics are discarded; unversioned diagnostics can only be associated with the arrival-time document revision. Editing clears previous annotations immediately. Server startup/transport failures are reported and clear that server's diagnostics; other servers and native editing remain available. There are no automatic restarts.
 
 Native LSP currently provides synchronization, diagnostics, and go-to-definition—not completion, hover, rename, formatting, code actions, workspace edits, or semantic highlighting. Tree-sitter remains the syntax highlighter. The former Ruby LSP plugin has been removed; migrate its `servers` entries to `config.lsp[language_id]` objects without the `language_id` field.
