 `: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, `config.core.lsp` exposes immutable Normal-mode Action objects: `definition`, `diagnostics`, and `hover`. Each routes to the same native implementation as its Ex command; no LSP keys are bound by default. These actions are also available in the command palette. The namespace is distinct from `config.lsp[language_id]` server configuration; flat Ruby LSP action members have been removed without aliases.
 
 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.
