The TUI also observes the editor's logical caret-reveal generation. Core motion/navigation dispatch advances it even when the resulting position is unchanged, so a detached viewport can resume following without duplicating key-binding policy or changing text revisions and LSP freshness.
Frontends inspect `palette()` for the optional read-only query, filtered command entries, selected index, effective bindings, and eligibility. Palette input handling and acceptance stay in the editor; registered command execution stays in the session.
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 `count()` for the optional pending numeric prefix; parsing, counted motion dispatch, and counted Normal line actions 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/Visual `gt`/`gb` prefix and Normal-only `gf`. Document-edge motions share multi-target motion dispatch and viewport reveal, retaining Visual anchors and selection shape. 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 `line_operator_pending()` for the optional Normal `d`/`c` prefix. Dedicated `dd`/`cc` actions project counted caret rows through existing linewise selection normalization, clipboard publication, and atomic range editing, without exposing a temporary Visual mode. Clipboard failures restore the original targets before returning. Repeat recipes retain the requested row count rather than the originally clamped range; change recipes share the existing Insert undo group. There is no general operator–motion parser.
Editor-owned jump history is a bounded 100-location `VecDeque` of buffer IDs and grapheme cursors plus a current index, with no copied paths/text. Successful high-level navigation records departure/destination once; traversal uses unrecorded buffer activation and position placement, skips closed/clamped-duplicate locations, and truncates forward entries only on a distinct new jump. Session synchronization permanently invalidates pending LSP position requests after their source buffer/revision/caret/mode is left, so returning through history cannot revive an old definition reply.
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.
