+# Phase 7: BackendDeveloper Main Process And Preload Implementation
+
+## Main Process Responsibilities Implemented
+
+- single-instance lock with focus restoration on second launch
+- secure `BrowserWindow` creation with `contextIsolation: true`, `nodeIntegration: false`, and `sandbox: true`
+- custom `app://` protocol for packaged renderer content
+- application menu, accelerators, native dialogs, and notifications
+- typed IPC registration with sender validation and schema validation
+- local SQLite profile bootstrap, backup, restore, and settings persistence
+- utility-process orchestration worker for run execution and log/status fan-out
+- updater wiring via `electron-updater`, gated by settings and environment
+
+## Preload Bridge
+
+- single exposed surface: `window.agentCompany`
+- no raw Node.js or Electron APIs exposed to renderer
+- typed invoke helpers only
+- renderer event subscription returns unsubscribe function and hides raw Electron event objects
+
+## Storage And Secrets
+
+- `node:sqlite` database under profile directory
+- WAL enabled
+- logs, artifacts, and backups stored as profile files
+- secrets encrypted with Electron `safeStorage` when available, otherwise vault fallback
+
