-# src/ Structure
-
-Three-process Electron architecture:
-
-## Processes
-- `main/` - Node.js runtime (file system, IPC, lifecycle)
-- `preload/` - Secure bridge (contextBridge API)
-- `renderer/` - React/Chromium (UI, state, visualization)
-- `shared/` - Cross-process types and utilities
-
-## Import Pattern
-Use barrel exports from domain folders:
-```typescript
-import { ChunkBuilder, ProjectScanner } from './services';
-```
-
-## IPC Communication
-Exposed API via `window.electronAPI`, organized by domain:
-
-| Domain | Methods | Examples |
-|--------|---------|---------|
-| Sessions | 10 | `getProjects()`, `getSessions()`, `getSessionsPaginated()`, `getSessionDetail()`, `getSessionMetrics()`, `getWaterfallData()`, `getSubagentDetail()`, `searchSessions()`, `getAppVersion()` |
-| Repository | 2 | `getRepositoryGroups()`, `getWorktreeSessions()` |
-| Validation | 2 | `validatePath()`, `validateMentions()` |
-| CLAUDE.md | 3 | `readClaudeMdFiles()`, `readDirectoryClaudeMd()`, `readMentionedFile()` |
-| Config | 16 | `config.get()`, `config.update()`, `config.addTrigger()`, `config.openInEditor()`, `config.pinSession()`, `config.unpinSession()`, etc. |
-| Notifications | 9 | `notifications.get()`, `notifications.markRead()`, `notifications.onNew()`, etc. |
-| Utilities | 7 | `openPath()`, `openExternal()`, `onFileChange()`, `onTodoChange()`, `getZoomFactor()`, `onZoomFactorChanged()` |
-| Session | 1 | `session.scrollToLine()` |
-
-Full API signatures in `src/preload/index.ts`, channel constants in `src/preload/constants/ipcChannels.ts`.

-# Main Process
-
-Node.js runtime handling file system, IPC, and app lifecycle.
-
-## Structure
-- `index.ts` - App entry point, lifecycle management
-- `ipc/` - IPC handlers organized by domain
-- `services/` - Business logic by domain
-- `types/` - Type definitions
-- `utils/` - Utility functions
-- `constants/` - Shared constants (messageTags, worktreePatterns)
-
-## IPC Organization
-Handlers in `ipc/` by domain:
-- `projects.ts` - Project listing
-- `sessions.ts` - Session operations
-- `search.ts` - Search functionality
-- `subagents.ts` - Subagent details
-- `validation.ts` - Path validation
-- `utility.ts` - Shell & file operations
-- `config.ts` - Configuration
-- `notifications.ts` - Notifications
-
-## Adding IPC Handler
-1. Add to domain file in `ipc/`
-2. If new domain, create file and register in `handlers.ts`
-3. Add type in `preload/index.ts`
-4. Implement in appropriate service
-
-## File Watching
-FileWatcher service monitors session files with 100ms debounce.
-Notifies renderer of changes via IPC events.

-# IPC Handlers
-
-Domain-organized IPC request handlers for main process.
-
-## Structure
-```
-ipc/
-├── handlers.ts          # Initialization and registration
-├── config.ts            # App configuration handlers
-├── configValidation.ts  # Config input validation/sanitization
-├── guards.ts            # IPC argument type guards
-├── notifications.ts     # Notification management
-├── projects.ts          # Project listing, repository grouping
-├── search.ts            # Session content search
-├── sessions.ts          # Session operations, pagination
-├── subagents.ts         # Subagent detail drill-down
-├── utility.ts           # Shell operations, file reading
-└── validation.ts        # Path validation, file mentioning
-```
-
-## Handler Pattern
-Each domain module exports:
-```typescript
-// Setup with services
-initialize{Domain}Handlers(services)
-
-// Register with ipcMain
-register{Domain}Handlers(ipcMain)
-
-// Cleanup on app quit
-remove{Domain}Handlers(ipcMain)
-```
-
-## Service Dependencies
-`initializeIpcHandlers()` receives service instances:
-- `ProjectScanner` - File system scanning
-- `SessionParser` - JSONL parsing
-- `SubagentResolver` - Subagent linking
-- `ChunkBuilder` - Chunk analysis
-- `DataCache` - Result caching
-
-## Response Pattern
-Config handlers use `IpcResult<T>` wrapper:
-```typescript
-return { success: true, data: result };
-return { success: false, error: message };
-```
-
-Other handlers return data directly or `null` on error.
-
-## Adding New Handler
-1. Add to existing domain file or create new file
-2. Call `initialize{Domain}Handlers()` if new domain
-3. Add `register/remove{Domain}Handlers` in `handlers.ts`
-4. Add channel constant in `preload/constants/ipcChannels.ts`
-5. Add method to ElectronAPI in `preload/index.ts`
-6. Implement service logic in `src/main/services/`

-
-Secure bridge between main and renderer processes via Electron's contextBridge.
-
-## Structure
-- `index.ts` - ElectronAPI implementation
-- `constants/ipcChannels.ts` - IPC channel name constants
-
-## ElectronAPI Organization
-Groups exposed methods by domain:
-
-### Session APIs
-- `getProjects()`, `getSessions()`, `getSessionsPaginated()`
-- `getSessionDetail()`, `getSessionMetrics()`, `getWaterfallData()`
-- `getSessionGroups()`, `searchSessions()`, `getAppVersion()`
-
-### Repository APIs
-- `getRepositoryGroups()`, `getWorktreeSessions()`
-
-### Validation APIs
-- `validatePath()`, `validateMentions()`
-
-### CLAUDE.md APIs
-- `readClaudeMdFiles()`, `readDirectoryClaudeMd()`, `readMentionedFile()`
-
-### Notifications
-- `notifications.{get,markRead,markAllRead,delete,clear,getUnreadCount}`
-- `notifications.{onNew,onUpdated,onClicked}` - Event listeners
-
-### Config API
-- `config.{get,update}` - Read/write config
-- `config.{addTrigger,updateTrigger,removeTrigger,getTriggers,testTrigger}`
-- `config.{addIgnoreRegex,removeIgnoreRegex,addIgnoreRepository,removeIgnoreRepository}`
-- `config.{snooze,clearSnooze,selectFolders}`
-- `config.{openInEditor,pinSession,unpinSession}`
-
-### Utilities

-- `onFileChange()` - File watcher events
-- `getZoomFactor()` - Get current zoom level
-- `onZoomFactorChanged()` - Zoom change listener
-- `session.scrollToLine()` - Deep link navigation
-
-## IPC Pattern
-Config operations use `IpcResult<T>` wrapper pattern:
-```typescript
-interface IpcResult<T> {
-  success: boolean;
-  data?: T;
-  error?: string;
-}
-```
-The `invokeIpcWithResult<T>()` helper unwraps and throws on failure.
-
-## Adding New IPC Methods
-1. Define channel constant in `constants/ipcChannels.ts`
-2. Implement handler in `src/main/ipc/{domain}.ts`
-3. Register in `handlers.ts` via `register{Domain}Handlers()`
-4. Add method to ElectronAPI in `preload/index.ts`

-
-## Adding Components
-1. Choose appropriate parent directory by feature
-2. If used across features, place in `common/`
-3. Use Tailwind with theme-aware CSS variables
-4. Connect to store via `useStore()` hook if needed
-5. Colocate related hooks/utils in same directory
-
-## Component Guidelines
-- One component per file, PascalCase naming
-- Use functional components with hooks
-- Prefer composition over prop drilling
-- Use `TabUIContext` for per-tab UI state
-
-## Virtual Scrolling
-Use `@tanstack/react-virtual` for lists > 100 items:
-- Session lists in sidebar
-- Message lists in chat view

-# Store (Zustand)
-
-State management with slices pattern for domain organization.
-
-## Structure
-- `index.ts` - Store creation, combines all slices
-- `types.ts` - AppState type definition
-- `slices/` - Individual domain slices
-- `utils/` - Store utilities (`paneHelpers.ts`, `pathResolution.ts`)
-
-## Slices (12 total)
-| Slice | Purpose |
-|-------|---------|
-| `projectSlice` | Projects list, selectedProjectId |
-| `repositorySlice` | Repository grouping, worktrees |
-| `sessionSlice` | Sessions list, pagination, selectedSessionId |
-| `sessionDetailSlice` | Session detail, chunks, metrics |
-| `subagentSlice` | Subagent data, selectedSubagentId |
-| `conversationSlice` | Messages, conversation metadata |
-| `tabSlice` | Tabs list, activeTabId, tab ordering |
-| `tabUISlice` | Per-tab UI state (expansions, scroll) |
-| `paneSlice` | Pane layout, split views |
-| `uiSlice` | UI flags (sidebar visible, etc.) |
-| `notificationSlice` | Notifications, unreadCount |
-| `configSlice` | App config, triggers |
-
-## Slice Pattern
-Each slice follows:
-```typescript
-data: T[]
-selectedId: string | null
-loading: boolean
-error: string | null
-```
-
-## Key Pattern: Per-Tab UI Isolation
-`tabUISlice` maintains independent UI state per tab using tabId:
-- `expandedAIGroupIds`, `expandedDisplayItemIds`, `expandedSubagentTraceIds`
-- Ensures expanding a group in tab A doesn't affect tab B
-
-## Store Initialization
-Call `initializeNotificationListeners()` once in App.tsx useEffect:
-- Subscribes to file change events
-- Auto-refreshes sessions on new files
-- Updates session detail on content change
-- Uses `refreshSessionInPlace` to prevent flickering
-
-## Adding a Slice
-1. Create `slices/{domain}Slice.ts`
-2. Export `create{Domain}Slice` function
-3. Add to store composition in `index.ts`
-4. Update `AppState` type in `types.ts`
