refactor: unified EditorPanel for notes and files, SaveFileText backend

- Create EditorPanel.svelte: shared editor component for notes + files
  - Markdown: edit/preview/split modes via MarkdownEditor + MarkdownPreview
  - Plain text: monospace textarea
  - Header: title, mode switcher, external open button
  - Footer: save + close buttons, dirty indicator
- Rewrite NoteEditorPanel.svelte as thin wrapper over EditorPanel
- FilesTab: browser/editor modes (editor replaces file list, not appended)
- Add SaveFileText Wails binding: writes text files atomically (tmp+rename)
- Add WriteText to files.Service with SHA256 update
- Remove separate TextFileEditor.svelte (replaced by EditorPanel)
- Note context: SaveNote API, noteId/title props
- File context: SaveFileText API, fileId prop
- Linked .md (CheckFileAction=note) → note editor tab
- Unlinked .md / text files → EditorPanel in FilesTab
- Images/PDF/binary → FilePreviewModal only

-# Frontend Architecture
+# Frontend Architecture — Verstak GUI
 
-## Overview
+## Tech Stack
 
-Verstak frontend is a Svelte 3 application running inside Wails v2 (Go bridge).
+- **Framework**: Svelte 4 (runes-free, compiler-only)
-The app manages a hierarchical vault of nodes (folders/cases, notes, files, links, actions)
+- **Build tool**: Vite 5
-with sync capabilities, worklog/journal, and activity tracking.
+- **GUI shell**: Wails v2 (Go backend + WebKit GTK frontend)
+- **Language**: Plain JavaScript (no TypeScript in Svelte files — `lang="ts"` is NOT used)
 
-## Technology Stack
+## Source Structure
-
-- **UI Framework:** Svelte 3 (plain JS, no TypeScript in components)
-- **Desktop Bridge:** Wails v2 (`window.go.main.App.*`)
-- **Bundler:** Vite (via Wails)
-- **Markdown:** Custom renderer in `lib/markdown/`
-- **i18n:** Custom lightweight system in `lib/i18n/`
-- **Styling:** Scoped CSS in Svelte components, dark theme

-## Wails Bridge
+## Role of App.svelte
 
-All backend calls go through `window.go.main.App[method](...)`.
+`App.svelte` is the **root component**. It owns:
-The `wailsCall()` helper in `lib/services/wails.js` provides error handling.
 
-## Planned Components (to extract from App.svelte)
+1. **Global UI state**: sidebar (system views, workspace tree), active tab, selected node/section
+2. **Lifecycle**: startup checks (GetStartupStatus, VerstakVersion, ListWorkspaceTree), event listeners
+3. **Top-level modals**: confirm, node rename, import (removed — now in FilesTab), worklog, inbox assign, link edit, settings, trash preview
+4. **Cross-cutting concerns**: navigation history (goBack, rememberNavigation), keyboard shortcuts, drag-and-drop orchestration, capture/inbox flow
+5. **Note editor lifecycle**: `noteEditor` state, `doOpenNote()`, `saveCurrentNote()`, `closeNoteEditor()`, link modal, internal link picker
 
-### Layout
+App.svelte is **NOT** responsible for:
-- `AppShell.svelte` — root layout wrapper
+- **Files tab** → `FilesTab.svelte` (owns all file browser state, preview, import, rename)
-- `Sidebar.svelte` — navigation sidebar
+- **Notes tab list** → `NotesTab.svelte` (owns note list UI, create form; editor stays in App)
-- `MainWorkspace.svelte` — main content area
+- **Overview tab** → `OverviewTab.svelte` (pure display: meta, quick actions, recent items)
+- **Settings sections** → each has its own `Settings*.svelte`
 
-### Pages/Tab Content
+## Component Communication
-- `OverviewTab.svelte` — node overview with meta and quick actions
-- `NotesTab.svelte` — notes list and creation
-- `FilesTab.svelte` — file browser with breadcrumbs
-- `InboxContent.svelte` + `InboxFullScreen.svelte`
-- `LinksTab.svelte`
-- `ActionsTab.svelte`
-- `WorklogTab.svelte`
-- `ActivityTabContent.svelte`
-- `TrashContent.svelte`
-- `JournalScreen.svelte`
-- `ActivityFeedScreen.svelte`
-- `WelcomeScreen.svelte`
 
-### Modals
+### Props (parent → child)
-- `CreateNodeModal.svelte`
+Data flows down via Svelte `export let prop`
-- `WorklogModal.svelte`
-- `CreateActionModal.svelte`
-- `ImportModal.svelte`
-- `RenameModal.svelte`
-- `AssignInboxModal.svelte`
-- `EditLinkModal.svelte`
-- `LinkInsertModal.svelte`
-- `NoteRenameModal.svelte`
-- `ContextMenu.svelte`
 
-## Data Flow
+### Events (child → parent)
+Children dispatch events via `createEventDispatcher()`
 
-1. User interacts with UI component
+### Public API (bind:this)
-2. Component calls a service function (e.g., `notesApi.createNote(...)`)
+Parent gets imperative handle via `bind:this={ref}` and calls:
-3. Service calls `wailsCall('CreateNote', ...)` 
+- `ref.publicMethod(args)` — guard with optional chaining: `ref?.method?.(args)`
-4. Wails bridge forwards to Go backend
-5. Go backend returns result → Wails → service → component updates state
 
-## State Management
+## Component Reference
 
-Currently all state lives in App.svelte as local variables.
+### OverviewTab (`lib/components/OverviewTab.svelte`)
-Target: extract into `lib/state/navigation.js` and `lib/state/uiState.js`.
+**Props**: `selectedNode`, `notes`, `worklog`, `formatDate`, `nodeKindLabel`
+**Events**: `createNote`, `addFile`, `createAction`, `switchTab`, `openNote`
+**State**: None (pure display)
 
-### Files Flow
+### NotesTab (`lib/components/notes/NotesTab.svelte`)
+**Props**: `notes`, `formatDate`
+**Events**: `submitCreateNote`({title}), `openNote`({note}), `startRename`({noteId, currentTitle}), `deleteNote`({note})
+**State**: `showCreateNote`, `newNoteTitle`
 
-- **Component:** `lib/components/files/FilesTab.svelte` — self-contained file browser
+### FilesTab (`lib/components/files/FilesTab.svelte`)
-- **API services:** `lib/services/files.js`, `lib/services/nodes.js`
+**Props**: `selectedNode`, `wailsCall`
-- **Events emitted:**
+**Events**: `openNote`({id, title}), `refreshParent`({nodeId}), `error`({message})
-  - `on:openNote` — when a .md file linked to a note is opened
+**Public API** (via bind:this):
-  - `on:refreshParent` — after file operations that modify the tree
+- `resetToNode(nodeId)` — reset to root of given node
-  - `on:error` — on operation failures
+- `addFile()` — open file picker and import
-  - `on:rename` — requests parent to show rename modal
+- `loadFolder(folderId)` — load folder contents
-  - `on:confirm` — requests parent to show confirm dialog
+- `openFileById(fileNodeId)` — find and preview file
-- **Public methods:**
+- `focusItem(nodeId)` — select item by ID
-  - `resetToNode(nodeId)` — reset state when selected node changes
+- `handleFilesKeydown(e)` — delegate keyboard handling
-  - `filesHandleKeydown(e)` — keyboard handler for files tab
+- `resetState()` — full reset (on node change)
-- **.md → note editor flow:** Handled inside FilesTab via `CheckFileAction` Wails call. If action is 'note', emits `openNote`. If 'external', opens in system viewer. Otherwise shows built-in preview.
-- **File preview:** `FilePreviewModal.svelte` (already existed), invoked by FilesTab
-- **Import dialog:** Inline in FilesTab template (moved from App.svelte)
 
-## Build & Verification
+**Internal state** (owned by FilesTab, NOT accessible from App):
+- `loadingFiles`, `currentFolderId`, `folderStack`, `fileItems`
+- `previewItem`, `previewContent`, `previewLoading`, `previewError`
+- `clipboard`, `selectedIds`, `dragIds`
+- `importing`, `importSummary`, `showImportDialog`, `pendingImportPath`, `pendingImportParent`
+- `showRename`, `renameId`, `renameValue`, `renameError`
+- `showConfirm`, `confirmTitle`, `confirmMessage`, `confirmAction`, `cancelAction`
 
-- `npm run build` in `frontend/` directory
+## State Ownership Rules
-- `go test ./...` from project root
+
-- `bash scripts/build.sh gui` for full GUI binary
+### App.svelte MUST own:
-- Manual smoke testing via Wails dev server
+- `selectedSection`, `selectedNode`, `activeTab`
+- `systemViews`, `workspaceTree`, `enabledTemplates`
+- `noteEditor` (the note being edited), `noteViewMode`
+- `showFirstRun`, `showRecovery`, `showSettings`, `loading`
+- `startupStatus`, `startupChecked`
+- Navigation state: `navHistory`, `restoringHistory`
+- Trash browser state: `trashInfo`, `trashCount`, `trashSelectedIds`, `trashFolderId`, `trashFolderStack`
+- Trash preview: `trashPreviewItem`, `trashPreviewContent`, `trashPreviewLoading`, `trashPreviewError`
+- Journal state: `journalRows`, `journalSummary`, filters
+- Worklog modal state: `showWorklogModal`, `wlModal*`
+- Inbox: `inboxNodes`, `localInboxNodes`, capture state
+- Links: `links`
+- Sync: `syncStatus`
+- `error` (global error banner)
+- `notes` (loaded by `loadTabData`, passed to NotesTab and OverviewTab as prop)
+- `worklog` (loaded by `loadTabData`, passed to OverviewTab as prop)
+
+### App.svelte must NOT directly reference:
+- Files tab internal state (all in FilesTab)
+- Notes tab create form state (showCreateNote, newNoteTitle — in NotesTab)
+- Any `fileItems`, `selectedIds`, `currentFolderId`, `folderStack`, etc.
+
+## Services (Wails API)
+
+All backend calls go through the `wailsCall()` helper in App.svelte:
+
+```js
+function wailsCall(method, ...args) {
+  // Returns Promise, rejects with 'Wails not connected: <method>' if backend unavailable
+}
+```
+
+Key backend methods:
+- **Startup**: `GetStartupStatus`, `VerstakVersion`, `ListSystemViewsWithPlugins`, `ListWorkspaceTree`, `ListEnabledTemplates`
+- **Nodes**: `GetNodeDetail`, `ListItems`, `ListWorkspaceChildren`, `CreateNodeFromTemplate`, `DeleteNode`, `MoveNode`, `RenameNode`
+- **Notes**: `ListNotes`, `CreateNote`, `ReadNote`, `SaveNote`, `DeleteNote`, `RenameNote`
+- **Files**: `ListFiles`, `DeleteFileOrFolder`, `CreateEmptyFile`, `DuplicateNode`, `OpenFile`, `OpenFolder`, `GetFileBase64`, `ReadFileText`, `PreviewImport`, `AddPathCopy`, `AddPathLink`
+- **Worklog**: `ListWorklog`, `CreateWorklogFull`, `UpdateWorklogEntry`, `DeleteWorklogEntry`, `AcceptSuggestionFull/With`, `GetSuggestions`
+- **Inbox**: `ListInboxNodes`, `Capture*WithContext`, `DeleteInboxNode`, `ResolveInboxNode`
+- **Sync**: `SyncStatus`, `SyncNow`, `TrashCount`, `ListTrash`
+- **Logging**: `FrontendLog(level, message, stack)`, `LogStartupStep(step, success, detail)`
+
+## Logging & Diagnostics
+
+### Frontend errors
+- Global `window.addEventListener('error', ...)` catches uncaught exceptions
+- Global `window.addEventListener('unhandledrejection', ...)` catches broken promises
+- Both log to `console.error` and forward to `FrontendLog()` backend binding
+- Fatal mount error: renders error message inline in `#app` div (blank window becomes diagnostic)
+
+### Backend logs
+- Application log file: `~/.local/state/verstak/logs/verstak.log` (Linux)
+- Fallback: `~/.config/verstak/logs/verstak.log`
+- Format: `[timestamp] [level] message`
+- Go `log.Printf()` output goes to stderr (visible in dev console)
+
+### Vault debug log
+- `<vault>/.verstak/debug.log` — written by `WriteDebugLog` binding (existing feature)
+
+## Refactor Rules
+
+### After each extraction step:
+1. `grep` App.svelte for state that moved to child — must be zero hits or documented exceptions
+2. `npm run build` — must pass
+3. `go test ./...` — must pass
+4. Manual GUI check:
+   - Window is not blank/white
+   - Sidebar shows (system views + workspace tree)
+   - No infinite "Загрузка..." on welcome screen
+   - Clicking system sections works
+   - Opening a case shows tabs
+
+### Forbidden patterns:
+- Child component state referenced directly in App.svelte after extraction
+- `lang="ts"` in Svelte files (svelte-preprocess not installed)
+- `[]string` passed directly to Wails bindings (must JSON-serialize)
+- Modal without `role="dialog" aria-modal="true"` and Escape handler
+- Buttons without `type="button"` in forms
+- `resize: none` on textareas that should be resizable (use `resize: vertical`)
+
+## Troubleshooting
+
+### Blank window, no errors in terminal
+1. Check browser DevTools console (F12 on Windows/Linux, Cmd+Alt+I on macOS)
+2. In Wails dev mode: right-click → Inspect → Console
+3. Look for `[Frontend Error]` messages
+4. Check application log: `~/.local/state/verstak/logs/verstak.log`
+
+### Stuck on "Загрузка..."
+- `GetStartupStatus` likely failed or returned unexpected status
+- Check network calls in DevTools Network tab
+- Check backend log for startup errors
+
+### Wails method not found
+- Ensure method is registered in `bindings*.go` files
+- Ensure method is exported (capitalized name)
+- Ensure `wailsCall()` helper is used (not direct window access)
+
+### Child component state moved but App still references old variable
+- This causes a silent `undefined` reference or runtime crash
+- Run `grep -n 'oldStateName' App.svelte` after each extraction
+- Use `ref?.method?.()` for all public API calls on child components

-
-## Phase 8: Verification
-
-- [ ] `npm run build` passes
-- [ ] `go test ./...` passes
-- [ ] Smoke checklist:
-  1. Sidebar renders with system views
-  2. Workspace tree loads and is expandable
-  3. Selecting a node shows tabs
-  4. Overview tab shows metadata and quick actions
-  5. Notes tab — create, rename, delete notes
-  6. Note editor — edit, preview, save, internal links, external links
-  7. Files tab — browse, add file/folder, navigate breadcrumbs
-  8. File preview — open, close
-  9. Inbox — list, sort, group, assign, delete
-  10. Trash — browse, restore, purge
-  11. Journal — filter, export, worklog CRUD
-  12. Activity feed — load and open events
-  13. Today screen — dashboard, suggestions, browser events
