feat(renderer): GitStatusPanel sidebar tab + git.refresh event

Adds the actual right-alignment heuristic to toAsciiTable (was missing
from initial implementation). When any column header starts with a digit,
all columns are right-padded instead of left-padded. Matches the test
added in 53870d5 which exercises the right-alignment path with header
['Item', '7'].

All 6 ascii-table tests pass.

+# Phase 8 — Toasts Design
+
+> Companion to the parent plan: `docs/superpowers/plans/2026-06-05-react-ui-redesign.md` (Phases 8+9+10 are sketched at high level; this spec locks Phase 8's architecture, file map, and contracts so it can be planned task-by-task.)
+
+**Date:** 2026-06-05
+**Phase:** 8 of 10 (React + shadcn/ui UI redesign)
+**Tag (on completion):** `phase-8-toasts`
+
+---
+
+## 1. Goal & Non-Goals
+
+**Goal:** Add a toast notification layer to the React renderer using sonner (already installed). Surface user-initiated async action results (file save, file/folder open, exports) as transient toasts in the bottom-right of the window. The error banner pattern in export dialogs stays — toasts are a complementary global channel.
+
+**Non-goals (Phase 8):**
+- Undo/redo support (Phase 9)
+- Custom toast actions/buttons (Phase 9, if needed)
+- Persistent notification history
+- Toast queueing/throttling for rapid-fire events
+- Replacing inline error banners (they stay as per-dialog context)
+
+**Scope decision:** Toast on user-initiated actions only. Skip silent background operations (loadChildren, etc.) to avoid noise. 4 wire points total: save (success+error), open file/folder (error only), 4 export dialogs (success+error).
+
+---
+
+## 2. Architecture
+
+### 2.1 Toast helpers in `lib/toast.ts`
+
+A thin typed layer over sonner. The helpers exist to:
+- Give us a single import surface (instead of scattering `import { toast } from 'sonner'` across the codebase)
+- Provide a place to add brand colors, formatting, or analytics later without touching call sites
+- Make mocking easier in tests (one module to mock)
+
+```ts
+// src/renderer/lib/toast.ts (sketch)
+import { toast as sonnerToast } from 'sonner';
+
+export const toast = {
+  success: (message: string) => sonnerToast.success(message),
+  error: (message: string) => sonnerToast.error(message),
+  info: (message: string) => sonnerToast.info(message),
+  warning: (message: string) => sonnerToast.warning(message),
+  promise: <T>(
+    promise: Promise<T>,
+    msgs: { loading: string; success: string | ((data: T) => string); error: string | ((err: unknown) => string) }
+  ) => sonnerToast.promise(promise, msgs),
+  dismiss: (id?: string | number) => sonnerToast.dismiss(id),
+};
+```
+
+### 2.2 `<Toaster />` mounted in App.tsx
+
+A canonical shadcn Toaster wrapper (manual paste per memory `shadcn-cli-blocked-manual-primitives`). Mounts alongside `<ModalLayer />`:
+
+```tsx
+// src/renderer/App.tsx (sketch)
+import { Toaster } from '@/components/ui/sonner';
+
+function App() {
+  useWelcomeTrigger();
+  return (
+    <>
+      <AppShell />
+      <ModalLayer />
+      <Toaster />
+    </>
+  );
+}
+```
+
+The Toaster uses sonner's `<Toaster />` component with:
+- `theme={resolvedTheme}` from `useTheme()` (so toasts match the user's light/dark preference)
+- `richColors` for semantic success/error/info/warning colors
+- `position="bottom-right"` (sonner default; explicit for clarity)
+- `closeButton` (so users can dismiss)
+
+### 2.3 Inline wiring at 4 wire points
+
+**Pattern choice — inline in stores/dialogs, NOT middleware.** Matches the Phase 7 precedent of inline error banners in export dialogs. Middleware would be DRY but harder to debug and harder to control granularity (we want errors on save, but NOT on silent loadChildren).
+
+**Wire points:**
+
+1. **`useFileStore.saveActiveBuffer`** — wrap the existing logic:
+   ```ts
+   saveActiveBuffer: async () => {
+     // ... existing logic to get buffer ...
+     const writeResult = await ipc.file.write(activeTabId, buffer.content);
+     if (!writeResult.ok) {
+       toast.error(`Failed to save: ${writeResult.error.message}`);
+       return false;
+     }
+     // ... existing markSaved/markTabClean ...
+     toast.success(`Saved ${title}`);
+     return true;
+   }
+   ```
+
+2. **`useFileStore.openFile`** — error only:
+   ```ts
+   openFile: async (filePath) => {
+     // ... existing logic to check existing tab ...
+     const result = await ipc.file.read(filePath);
+     if (!result.ok) {
+       toast.error(`Failed to open file: ${result.error.message}`);
+       return;
+     }
+     // ... existing logic ...
+   }
+   ```
+
+3. **`useFileStore.openFolder`** — error only:
+   ```ts
+   openFolder: async (path) => {
+     const result = await ipc.file.list(path);
+     if (!result.ok) {
+       toast.error(`Failed to open folder: ${result.error.message}`);
+       return;
+     }
+     // ... existing logic ...
+   }
+   ```
+
+4. **4 export dialogs** — both success and error (error complements the inline banner):
+   ```ts
+   if (!result.ok) {
+     toast.error(`Export failed: ${result.error.message}`);
+     setError(result.error.message);
+     setSubmitting(false);
+   } else {
+     toast.success(`Exported ${source.title} to ${result.data?.outputPath ?? 'file'}`);
+     closeModal();
+   }
+   ```
+
+---
+
+## 3. File Map
+
+### 3.1 Created files
+
+- `src/renderer/lib/toast.ts` — typed wrappers (re-export of sonner with our naming)
+- `src/renderer/components/ui/sonner.tsx` — canonical shadcn Toaster wrapper (manual paste)
+- `tests/unit/lib/toast.test.ts` — ~5 unit tests
+- `tests/component/ui/sonner.test.tsx` — 1 smoke test
+- `tests/integration/phase8-toasts-smoke.test.tsx` — ~4 integration tests
+
+### 3.2 Modified files
+
+- `src/renderer/App.tsx` — mount `<Toaster />` alongside `<ModalLayer />`
+- `src/renderer/stores/file-store.ts` — add 3 toast calls (save, openFile, openFolder)
+- `src/renderer/components/modals/ExportPdfDialog.tsx` — toast on submit result
+- `src/renderer/components/modals/ExportDocxDialog.tsx` — toast on submit result
+- `src/renderer/components/modals/ExportHtmlDialog.tsx` — toast on submit result
+- `src/renderer/components/modals/ExportBatchDialog.tsx` — toast on submit result
+
+---
+
+## 4. Data Flow
+
+User action → store action OR export dialog submit → IPC call → result →
+- if error: `toast.error(message)` → sonner renders in bottom-right portal
+- if success: `toast.success(message)` → sonner renders
+- inline error banner in dialog stays as per-dialog context (NOT removed)
+
+Theme comes from `useTheme()` in the Toaster component, not from individual toasts. The Toaster is mounted once at the app level.
+
+For the 4 export dialogs: the existing inline error banner stays (it's contextual to the dialog), AND a toast is fired. This gives the user both immediate context (in the dialog) and persistent notification (toast in corner).
+
+For file save: ONLY a toast (no inline error UI in the editor pane — keeps the editor clean). Errors still show the toast.
+
+---
+
+## 5. Error Handling
+
+- **Toast helpers never throw.** They are thin re-exports of sonner, which handles its own error cases (e.g., render failures, missing portal target).
+- **In tests**, the `toast` module is mocked so calls don't render real toasts. Mock signature: `vi.mock('@/lib/toast', () => ({ toast: { success: vi.fn(), error: vi.fn(), ... } }))`.
+- **Theme fallback:** If `useTheme()` is loading or `resolvedTheme` is undefined, Toaster uses `'system'` as a fallback (sonner's default behavior).
+- **Sonner missing:** If for some reason sonner fails to load, the toast calls become no-ops. The user still sees inline error banners in the export dialogs.
+- **Inline error banners stay.** They are not replaced by toasts — they complement them.
+
+---
+
+## 6. Testing Strategy
+
+### 6.1 Unit tests (`tests/unit/lib/toast.test.ts`)
+
+5 tests:
+- `toast.success` calls sonner `toast.success` with the message
+- `toast.error` calls sonner `toast.error` with the message
+- `toast.info` calls sonner `toast.info`
+- `toast.warning` calls sonner `toast.warning`
+- `toast.promise` forwards the promise and messages to sonner
+
+All tests mock the sonner module and verify the forwarded call.
+
+### 6.2 Component test (`tests/component/ui/sonner.test.tsx`)
+
+1 smoke test: `<Toaster />` renders without crashing inside a ThemeProvider.
+
+### 6.3 Integration test (`tests/integration/phase8-toasts-smoke.test.tsx`)
+
+~4 tests:
+- Saving a file → `toast.success` called with `"Saved test.md"`
+- Opening a non-existent file (ipc returns error) → `toast.error` called with file path in message
+- Export success (ipc returns ok) → `toast.success` called + dialog closes
+- Export failure (ipc returns error) → `toast.error` called + inline banner shown + dialog stays open
+
+TDD throughout. Mocks for `ipc.*` and `lib/toast`.
+
+### 6.4 Existing tests must still pass
+
+- All 243 tests from Phase 7 must remain green
+- Export dialog tests will need updates to verify the new toast calls (the dialog tests currently check for inline banner; they should ALSO verify the toast call)
+
+---
+
+## 7. Risks & Open Questions
+
+**Risks:**
+- **Sonner theme switching:** If `useTheme()` returns `'system'` and the OS preference changes mid-session, sonner will re-render. This is the correct behavior; just confirm in test.
+- **Toast spam:** If user holds Cmd+S, the save could fire many times. Sonner deduplicates by default for similar messages? → Decision: rely on sonner's default behavior. If spam becomes an issue, add a `toast.dismiss()` debounce in v2.
+
+**Open questions (deferrable):**
+- Should we add a custom toast for "undo last close" (Phase 9's undo feature)? → Decision: out of scope for Phase 8. Phase 9 will handle undo toasts.
+- Should the export dialog inline banner be removed once toasts are wired? → Decision: NO — keep both. The inline banner is contextual to the dialog; the toast is global. They serve different purposes.
+
+---
+
+## 8. Out of Scope (deferred to later phases)
+
+- Phase 9: Undo toasts ("Tab closed — Undo" with action button)
+- Phase 9: Long-running operation progress toasts (e.g., batch export queue)
+- Phase 9: Custom toast variants for advanced tools (ASCII generator, table generator)
+- Phase 10: Cleanup of inline error banners (will evaluate in Phase 10 if redundant)
+
+---
+
+## 9. Success Criteria
+
+Phase 8 is complete when:
+- `lib/toast.ts` exists with typed wrappers
+- `<Toaster />` is mounted in `App.tsx` and renders toasts
+- `useFileStore.saveActiveBuffer` calls `toast.success`/`toast.error` on result
+- `useFileStore.openFile` calls `toast.error` on failure
+- `useFileStore.openFolder` calls `toast.error` on failure
+- 4 export dialogs call `toast.success`/`toast.error` on result
+- All tests pass: ~+10 new tests, total ~253
+- `npx vite build` succeeds
+- Branch tagged `phase-8-toasts` and pushed to origin

+# Phase 9 — Advanced Tools Design
+
+> Companion to the parent plan: `docs/superpowers/plans/2026-06-05-react-ui-redesign.md` (Phase 9 is sketched at high level; this spec locks architecture, file map, and contracts so it can be planned task-by-task.)
+
+**Date:** 2026-06-05
+**Phase:** 9 of 10 (React + shadcn/ui UI redesign)
+**Tag (on completion):** `phase-9-advanced-tools`
+
+---
+
+## 1. Goal & Non-Goals
+
+**Goal:** Add 10 advanced tools to the React renderer. Group 1: Standalone dialogs (ASCII generator, Table generator, Word export, Find-in-files). Group 2: Global overlays (Zen mode, REPL, Print preview). Group 3: Editor/sidebar integrations (Minimap, Breadcrumbs-with-symbols, Git status). All triggered via the Phase 6 command store.
+
+**Non-goals (Phase 9):**
+- True undo/redo stack (still not in scope)
+- Snippet/template library
+- Custom REPL with full JS eval (we chose markdown snippet preview for safety)
+- Custom diff/merge UI (just shows git status, no in-app diffing)
+- Plug-in extensions
+- Multi-cursor editing
+- LSP / language server integration
+
+**Decision summary (from brainstorming):**
+- REPL = **markdown snippet preview** (no JS eval — safe in renderer)
+- Word export = **`.docx` via `docx` lib in renderer**, with both Standard and Custom .dotx template modes
+- Find-in-files = **recursive search with result navigation** (new IPC, regex support)
+
+---
+
+## 2. Architecture
+
+### 2.1 Three mount strategies
+
+| Category | Mount | Examples |
+|---|---|---|
+| **Dialogs** | `<ModalLayer />` (Phase 7 pattern) | ASCII gen, Table gen, Word export, Find-in-files |
+| **Global overlays** | Top-level in `App.tsx` (like `<Toaster />`) | Zen mode, REPL panel, Print preview |
+| **Editor/sidebar integrations** | Extend existing components | Minimap, Breadcrumbs, Git status |
+
+The ModalLayer is the dispatcher for dialogs. The global overlays are mounted directly in `App.tsx` because they need to participate in the top-level layout (full-window, or pinned to the bottom).
+
+### 2.2 ModalState union extension
+
+The Phase 7 `ModalState` discriminated union (9 kinds) gets 4 new kinds for the new dialogs:
+
+```ts
+export type ModalState =
+  | { kind: null }
+  | { kind: 'export-pdf'; props: { sourcePath: string } }
+  | { kind: 'export-docx'; props: { sourcePath: string } }
+  | { kind: 'export-html'; props: { sourcePath: string } }
+  | { kind: 'export-batch'; props: { sourcePaths: string[] } }
+  | { kind: 'export-word'; props: { sourcePath: string } }   // NEW
+  | { kind: 'ascii-generator' }                                  // NEW
+  | { kind: 'table-generator' }                                  // NEW
+  | { kind: 'find-in-files' }                                    // NEW
+  | { kind: 'settings' }
+  | { kind: 'about' }
+  | { kind: 'welcome' }
+  | { kind: 'confirm'; props: ConfirmProps };
+```
+
+Three of the four new kinds (ascii, table, find-in-files) take no props — they read from the active buffer via `useExportSource` (for ascii/table) or from `useFileStore.rootPath` (for find-in-files). `export-word` takes `sourcePath` like the other export dialogs.
+
+### 2.3 New commands in command store
+
+| Command ID | Trigger | Opens |
+|---|---|---|
+| `tools.ascii` | new | `AsciiGeneratorDialog` |
+| `tools.table` | new | `TableGeneratorDialog` |
+| `tools.exportWord` | new | `WordExportDialog` |
+| `tools.findInFiles` | new | `FindInFilesDialog` |
+| `tools.repl` | new | toggles REPL panel |
+| `view.zenMode` | existing (Phase 6) | toggles Zen mode overlay |
+| `file.print` | new | opens `PrintPreview` overlay |
+| `git.refresh` | new | re-fetches git status |
+
+All registered in `src/renderer/lib/commands/register-menu-commands.ts`.
+
+### 2.4 New IPC surface
+
+```ts
+// src/renderer/lib/ipc.ts (additions)
+ipc.file.search({ rootPath, query, isRegex, caseSensitive }: {
+  rootPath: string;
+  query: string;
+  isRegex: boolean;
+  caseSensitive: boolean;
+}): Promise<IpcResult<Array<{ filePath: string; line: number; content: string }>>>;
+
+ipc.file.gitStatus({ rootPath }: { rootPath: string }): Promise<IpcResult<Array<{ filePath: string; status: 'modified' | 'added' | 'deleted' | 'untracked' }>>>;
+
+ipc.file.print({ html }: { html: string }): Promise<IpcResult<void>>;
+
+ipc.file.writeBuffer({ path, buffer }: { path: string; buffer: Uint8Array }): Promise<IpcResult<void>>;
+```
+
+The main process counterparts are added to `src/main.js` (or a new `src/main/files-search.js`, etc.). For Phase 9, the spec covers the renderer-side design; main-process IPC handlers are assumed to follow the same `ipcMain.handle` pattern as the existing handlers.
+
+### 2.5 Settings additions (`useSettingsStore`)
+
+```ts
+// zod schema additions:
+docxCustomTemplatePath: z.string().nullable().default(null),  // path to user .dotx file
+replOpen: z.boolean().default(false),                         // REPL panel visibility
+breadcrumbSymbols: z.boolean().default(true),                  // breadcrumbs show code symbols
+// minimap already exists from Phase 7 (useSettingsStore.minimap: z.boolean().default(true))
+```
+
+The `minimap` setting from Phase 7 is now wired (not just stored).
+
+---
+
+## 3. File Map
+
+### 3.1 Created files
+
+**Dialogs (in `src/renderer/components/modals/`):**
+- `AsciiGeneratorDialog.tsx` — input textarea, font select, output preview with copy button
+- `TableGeneratorDialog.tsx` — rows × cols inputs, header checkbox, output preview
+- `WordExportDialog.tsx` — template select (Standard / Custom .dotx), options, preview, export
+- `FindInFilesDialog.tsx` — query input, regex/case toggles, results list with click-to-navigate
+
+**Global overlays (in `src/renderer/components/tools/`):**
+- `ReplPanel.tsx` — bottom-pinned, textarea + rendered preview
+- `PrintPreview.tsx` — full-window print preview
+
+**Editor/sidebar integrations:**
+- `src/renderer/components/layout/ZenMode.tsx` — wraps/controls the editor in zen mode (or modify `AppShell.tsx` to hide chrome)
+- `src/renderer/components/sidebar/GitStatusPanel.tsx` — file list with status badges
+
+**Lib:**
+- `src/renderer/lib/docx-export.ts` — renderer-side `docx` lib integration (markdown → Blob)

+- `tests/integration/phase9-tools-smoke.test.tsx` — 6 tests (one per command-triggered tool)
+

+
+## 4. Data Flow
+
+### 4.1 Word export (most complex)
+
+1. User triggers `tools.exportWord` → `registerMenuCommands` opens the export-word modal via `useAppStore.openModal('export-word', { sourcePath: activeTabId })`
+2. **Wait** — we need a new modal kind `export-word` in the `ModalState` union. Add it.
+3. `WordExportDialog` (mounted by ModalLayer) shows:
+   - Template select: "Standard (bundled)" or "Custom .dotx (your file)" — pre-populated with `useSettingsStore.docxCustomTemplatePath`
+   - "Choose custom template..." button (file picker, saves to settings)
+   - Options: embed images (checkbox), include front matter (checkbox)
+   - Preview area: shows the generated docx structure (sizes, table of contents)
+4. On submit:
+   - Renderer calls `lib/docx-export.ts#generateDocx(source, templatePath, options)` which uses the `docx` lib
+   - The lib takes a `Document` AST and produces a Blob
+   - ASCII tables are converted to monospace `<w:r>` runs (using `applyAsciiTransform` from Phase 7)
+   - Images are extracted from markdown and embedded as base64
+   - If a custom .dotx path is set, the renderer reads it via `ipc.file.read` and applies its styles (via `docx` lib's style support)
+   - User picks output path via `ipc.app.showSaveDialog`
+   - Writes Blob via `ipc.file.writeBuffer` (new)
+   - Toast success/failure
+
+### 4.2 Find-in-files
+
+1. User triggers `tools.findInFiles` → ModalLayer opens `FindInFilesDialog`
+2. User types query, picks regex/literal, case-sensitive toggle
+3. On submit: `ipc.file.search({ rootPath: useFileStore.rootPath, query, isRegex, caseSensitive })`
+4. Backend walks the disk recursively, applies regex/literal match, returns `Array<{ filePath, line, content }>`
+5. Dialog shows result list (file:line:content, clickable)
+6. Click a result:
+   - `useFileStore.openFile(filePath)` if not already open
+   - Set the cursor in the editor to the matched line
+7. Close the dialog
+
+### 4.3 REPL (markdown snippet preview)
+
+1. User triggers `tools.repl` → toggles `useSettingsStore.replOpen` (or a new dedicated `useReplStore`)
+2. `ReplPanel` (mounted in App.tsx) is visible when `replOpen === true`
+3. The panel has:
+   - Top half: textarea (user types/pastes markdown)
+   - Bottom half: rendered preview (uses `lib/markdown.ts` from Phase 1 + DOMPurify)
+4. Updates are debounced (300ms) for the preview
+5. Pure renderer-side, no IPC
+
+### 4.4 Zen mode
+
+1. User triggers `view.zenMode` → toggles `useSettingsStore.zenMode`
+2. `AppShell` reads `zenMode` from store; when true, hides all chrome (header, tabs, toolbar, breadcrumb, status bar, sidebar)
+3. Editor goes fullscreen
+4. Pressing Esc exits zen mode (keydown listener in `use-zen-mode` hook)
+
+### 4.5 Print preview
+
+1. User triggers `file.print` → opens `PrintPreview` (full-window overlay)
+2. The preview renders the current buffer's content as it would appear in print
+3. Two buttons: "Print" (calls `ipc.file.print({ html })` which opens native print dialog) and "Close"
+
+### 4.6 Minimap
+
+1. `useSettingsStore.minimap` (existing setting) is read by `CodeMirrorEditor`
+2. When true, the editor's extension includes `@replit/codemirror-minimap` (or a simpler custom implementation)
+3. The minimap shows a shrunk version of the document on the right side of the editor
+4. Toggling the setting adds/removes the extension dynamically
+
+### 4.7 Breadcrumbs-with-symbols
+
+1. The current `Breadcrumb` shows the file path. Extend it to also show markdown symbols (headings, code blocks)
+2. Use a simple AST walk of the current buffer to extract heading levels
+3. Show as a path-like navigation: `file.md > H1: Title > H2: Section > #line`
+4. The `useSettingsStore.breadcrumbSymbols` toggle (default true) controls whether symbols are shown
+
+### 4.8 Git status
+
+1. On sidebar Git tab open, fetch `ipc.file.gitStatus({ rootPath: useFileStore.rootPath })`
+2. The main process runs `git status --porcelain` (or equivalent) and returns the list
+3. Show file list with status badges (M, A, D, ?)
+4. Click a file opens it via `useFileStore.openFile`
+5. `git.refresh` re-fetches
+
+---
+
+## 5. Error Handling
+
+- **Word export failures:** `lib/docx-export.ts` catches `docx` lib errors → toast.error
+- **Word export missing .dotx:** if custom template path is set but file doesn't exist, show inline banner in the dialog
+- **Find-in-files failures:** if `ipc.file.search` throws (regex syntax error, IO error), show inline banner in the dialog
+- **REPL:** no IPC, no error handling needed
+- **Git status:** if folder isn't a git repo, return empty array. Panel shows "Not a git repository" message
+- **Print:** if `ipc.file.print` fails (no printer, user cancels), toast.error or silent close
+- **Minimap, Breadcrumbs:** renderer-side, no errors
+
+---
+
+## 6. Testing Strategy
+
+- **Unit tests:** `lib/docx-export.ts` (markdown → docx conversion, ASCII handling), `lib/ascii-table.ts` (already tested)
+- **Component tests:** 1-2 smoke tests per new component
+- **Integration test:** `phase9-tools-smoke.test.tsx` covering the 6 command-triggered tools (dispatch opens correct modal/overlay)
+- **Editor integrations:** minimap toggle, breadcrumbs render with symbols, git status panel render
+- **Target: +30-40 new tests**, total ~290
+
+---
+
+## 7. Risks & Open Questions

+**Risks:**
+- **`docx` lib bundle size (~500KB).** Acceptable for a desktop app but worth noting. Lazy-load if it becomes a concern.
+- **Word export custom template parsing** — the `.dotx` format is a zip with XML inside. The `docx` lib may not fully support reading existing templates. v1 may need a simpler "styles only" extraction.
+- **Find-in-files regex compilation** — invalid regex would throw. Validate on the renderer before calling IPC.
+- **Minimap performance** — for large files, the minimap can slow down scrolling. CodeMirror's built-in minimap has performance options to configure.
+
+**Open questions (deferrable):**
+- **REPL persistence** — should the textarea content survive across modal close/reopen? → Decision: NO for v1. Keep simple.
+- **Git status auto-refresh** — should it auto-refresh every N seconds? → Decision: NO for v1. Manual via `git.refresh` command.
+- **Find-in-files result count limit** — what if there are 10,000 matches? → Decision: limit to 500 results for v1, show "X more matches" message.
+
+---
+
+## 8. Out of Scope (deferred to Phase 10 or later)
+
+- Custom undo/redo (still not in scope)
+- Snippet/template library
+- Multi-cursor editing
+- LSP / language server
+- Phase 10 will delete legacy files including the old `src/print-preview.js`, `src/wordTemplateExporter.js`, `src/welcome.js`, `src/zen-mode.js`, etc.
+
+---
+
+## 9. Success Criteria
+
+Phase 9 is complete when:
+- All 10 features implemented and accessible via the command store
+- `lib/docx-export.ts` generates valid `.docx` files
+- Find-in-files returns results from a recursive disk walk
+- REPL renders markdown snippet previews
+- Zen mode hides all chrome and Esc exits
+- Print preview opens native print dialog
+- Minimap appears when `useSettingsStore.minimap` is true
+- Breadcrumbs show symbols by default
+- Git status panel shows modified/added/deleted/untracked files
+- ~+30-40 new tests, total ~290
+- `npx vite build` succeeds
+- Branch tagged `phase-9-advanced-tools` and pushed to origin
