 - `files`: owns the gitignore-aware directory/file catalog, authoritative OS paths, compact tree projection, query filtering, browse/search focus, expansion/selection restoration, navigation, and scan/error state shared by floating and docked presentations.
 - `clipboard`: owns native plain-text provider selection and bounded subprocess I/O; it never computes selections or editing offsets.
 - `syntax`: owns Tree-sitter grammar detection, per-buffer incremental trees, bundled highlight/local/injection queries, and syntax byte spans; it has no terminal color/geometry or editing dependency.
+- `markdown`: owns native Markdown link/reference resolution, local destination decoding, and heading fragment lookup through the installed block/inline grammars. It has no editor lifecycle, terminal, LSP, or external-process dependency.
 - `plugin`: owns generic document snapshots/events, zero-based grapheme positions, diagnostics, frontend-independent semantic token kinds/modifiers, and versioned asynchronous update contracts. Semantic token updates are native-only, not part of the Ruby wire protocol; it has no LSP protocol types.
 - `lsp`: owns opt-in native server workers, bounded framed JSON-RPC, synchronization/capability negotiation, settings, UTF-16/file-URI conversion, definition/hover results, and semantic token requests/legend decoding. Its private configuration resolver supplies presets without restricting language IDs.
 - `session`: `EditorSession` owns the editor, native LSP, and Ruby hosts together. It loads configuration once, registers eligible plugins before installing shared bindings, tracks document open/change/save/close events, polls native and plugin results, validates versioned diagnostics/navigation, and retires failed plugin ownership.

 Frontends use cached `selection_navigation_hint()` for command lists and `file_navigation_hint()` for the active file view/context, without reconstructing input policy.
 Frontends inspect `count()` for the optional pending motion prefix; parsing and counted motion dispatch remain editor-owned.
 Frontends inspect `leader_pending()` for the cached display of a pending leader sequence; prefix recognition, cancellation, and dispatch remain editor-owned.
+Frontends inspect `g_pending()` for the built-in Normal `gf` prefix. Markdown following preflights links and headings before buffer/caret mutation; an unloaded target is validated/prepared once, while loaded targets use their current unsaved text. File identity and activation stay editor-owned.
 Frontends inspect `buffer_id()`, `buffer_count()`, `has_buffer(id)`, and the ascending-ID `buffers()` iterator of borrowed path/dirty/active metadata. Existing text, cursor, selection, search, and mode methods describe only the active buffer.
 Frontends inspect `file_picker()` for query, presentation, view, explorer-local INSERT/filter subfocus, selection, and errors, and iterate borrowed `FileRow` metadata (actual path, display label, directory flag, visible depth, expansion). Dock side is a logical preference. They allocate rectangles, add folder suffixes/colors, and render; hierarchy, filtering, parent/child navigation, focus transitions, and selected-file opening remain backend-owned.
 Frontends inspect `diagnostics()` and `diagnostic_at_cursor()` for validated active-buffer annotations. Diagnostics are owned by core LSP or a plugin and buffer revision; text changes clear them. Native server retirement removes only that server's contribution, preserving sibling diagnostics. The TUI underlines annotated text, colors affected gutter numbers by severity, and displays the primary caret's diagnostic message without replacing search/selection backgrounds.
