 Current-line blame is enabled by default. Session loads whole-file incremental attribution into one active-buffer cache keyed by buffer/text/save revision, disk stamp, and path; cursor, tab, and pane movements within that source reuse it without copying file text or issuing repository commands. Cold results select the current row when they arrive. Edits, saves, source changes, disk refreshes, focus regain, and disabling invalidate attribution; stale results cannot replace a newer source. Metadata is shared per commit with `Arc`, and same-commit navigation reuses the sanitized label. Rendering uses only spare cells after the current logical line's final visible continuation and hides it when the primary caret is offscreen. Disabling drops the worker; comparisons and immutable buffers never schedule live blame.
 
-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).

 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 full editor area 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.

 Repository gutter work runs off the render/editor thread. Revision/path-validated marker vectors belong to ordinary source buffers, not historical snapshots; panes and tabs borrow their own buffer's markers. The worker compares editor text with Git HEAD or Git-backed jj's single parent, independently of save baselines and index state. The frontend paints green additions, red deletion anchors, and yellow modifications as `▌`, symbols, or number colors; current-line cyan/bold overrides repository colors in number-color mode.
 
+The same cancellable worker optionally collects normal-picker status, including when line-gutter rendering is disabled. Disk metadata and dirty-buffer overlays use Git HEAD or jj's single parent without snapshotting jj or writing active refs, objects, or indexes. A private baseline index retains its stat cache across polls; conflicted jj parents are projected once per root/parent. Root, baseline, store, or builtin Git conversion-setting changes invalidate that cache. Private queries disable user filters, external diff, and textconv. Request/tab/root checks reject stale picker results; unchanged catalogs retain their ordinary scanner and filtering rules.

 ## Syntax caches
 
 Each buffer has a frontend-owned parser/tree cache. Unchanged revision/path skips comparison and parsing; unchanged text at a later revision also avoids parsing. Actual text changes produce a minimal UTF-8-safe byte edit with newline-aware Tree-sitter Points, edit the prior tree, then parse using that tree for incremental reuse. Grammar changes reset the tree, including TypeScript versus TSX despite their shared display name. Native highlight/local/injection queries resolve capture precedence and scoped definitions into nonoverlapping original-line spans; unchanged injected trees are reused. Buffer switching restores its cache, and closing retires it. Incomplete text and grammar ERROR nodes remain highlightable; genuine language/query/parser failures expose a status error and readable plain text. Full-tree highlight queries still run after incremental parsing—a deliberate ceiling to revisit if measured costly. There is no local semantic inference engine or runtime grammar download.

 Indicators compare the current editor text (including unsaved edits) against Git `HEAD`, or the parent `@-` in Git-backed jj repositories, rather than against the last save or Git index. Line endings use the editor's LF normalization. They refresh after edits/saves, on focus regain, and once per second for repository changes. Historical snapshots do not receive live indicators. Eligible named files not yet on disk show nonempty unsaved text as added; tracked files missing on disk still compare their buffer text against the baseline. Non-repository, ignored, binary, symlink, and unsupported files have no indicators; neither do jj working changes with multiple parents. Both colocated and non-colocated Git-backed jj repositories are supported. Files above 16 MiB report an error and clear their indicators; request batches are limited to 64 MiB or 1024 files.

Definition routing must distinguish ranges overlapping actual changed rows from wholly unchanged/context/omitted targets, use full location-link target ranges with exact selection reveal and exclusive endpoints, route canonical aliases and old/new rename paths, load other changed files on demand, handle added/deleted files, preserve original tabs/panes/excerpts and shared dirty targets, retain snapshot identity in ordinary tabs, and fail atomically for missing/non-UTF-8 files, invalid ranges, and unsupported URIs.
