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.
Frontends borrow `semantic_tokens()` for sorted, single-line grapheme spans from the active buffer. Immutable `Arc` slices are shared by native LSP and buffer storage; painting does not copy tokens. Text/path changes discard overlays, and native updates validate the whole applicable annotation batch before mutation. The TUI merges semantic styling into its existing glyph pass above syntax foregrounds but below diagnostic/search/selection/caret styling.
Frontends inspect `hover()` for optional read-only content and logical-line/grapheme scroll offsets. Popup request eligibility, dismissal, and scrolling stay editor/session-owned; the TUI clips the panel inside the document workspace without changing the primary cursor or viewport. Its hover-local syntax cache treats content as Markdown, including named fenced-code injections, and rebuilds only when content changes. The popup shares the document syntax palette and preserves raw Markdown text and logical scroll coordinates.
Frontends borrow `completion()` for the read-only item list and selected index: zero is Original text, and other indices select `items[selected - 1]`. The editor owns the immutable original document/carets, atomic candidate transactions, cycling/dismissal, pending Insert undo, and final-only repeat recording. It changes only the primary completion target and translates secondary carets through all edits. The TUI only places a windowed list near the current caret inside the document text workspace, sanitizes/clips labels and detail by grapheme, and preserves gutter, explorer, and hardware cursor ownership; wheel input over the list is consumed without dispatching edits.

The TUI places a windowed list near the current caret, bounded by the full editor rather than its pane, sanitizes/clips labels and detail by grapheme, and preserves hardware cursor ownership; wheel input over the list is consumed without dispatching edits.
Frontends borrow `snippet_selections()` for the active argument's end-exclusive grapheme ranges, including mirrors and empty tabstops. The editor caches those ranges after previews, argument edits, and navigation; rendering adds no snippet allocation. Template edits stay primary-only, translate other carets, and fold resolved replacement text and caret placement into the pending completion repeat step. Per-occurrence ancestry distinguishes nested arguments from adjacent empty stops, allowing enclosing replacements to retire only overwritten descendants.
