-## Architecture Overview
+## Architecture
 
-Adiuva is a local-first Electron desktop app. The three Electron processes communicate via a custom tRPC↔IPC bridge (the public `electron-trpc` package is incompatible with tRPC v11, so a custom implementation is used).

 ```
 
-1. **Main process** (`src/main/`) — Node.js, owns the database and all business logic
+### Main Process (`src/main/`)
-   - `index.ts` — Window creation, app lifecycle
-   - `ipc.ts` — Custom handler that bridges `ipcMain` to tRPC procedures
-   - `router/index.ts` — All tRPC routers (clients, projects, tasks, checkpoints, notes, settings, ai)
-   - `db/index.ts` — Drizzle + better-sqlite3, WAL mode, singleton `getDb()`
-   - `db/schema.ts` — All table definitions (clients, projects, tasks, checkpoints, notes)
-   - `store.ts` — electron-store for persistent UI settings (e.g., `sidebarCollapsed`)
 
-2. **Preload** (`src/preload/trpc.ts`) — Exposes `window.electronTRPC` with `sendMessage()` / `onMessage()`

+| File | Purpose |
-   - `lib/ipcLink.ts` — Custom TRPCLink that routes calls through `window.electronTRPC`
+|---|---|
-   - `lib/trpc.ts` — `createTRPCReact<AppRouter>()` typed client
+| `index.ts` | Window creation, app lifecycle |
-   - `index.tsx` — QueryClient + tRPC + Router providers
+| `ipc.ts` | Bridges `ipcMain` to tRPC procedures |
-   - All data access is through `trpc.*.*useQuery()` / `trpc.*.*.useMutation()`

 ### Routing
 
-File-based routing via TanStack Router. Add a file to `src/renderer/routes/` and the route tree (`src/renderer/routeTree.gen.ts`) is auto-regenerated by the Vite plugin on next `npm start`. Routes:
+File-based via TanStack Router (`tsr.config.json` at root). Route tree auto-generated at `routeTree.gen.ts`.
-- `__root.tsx` — Root layout wrapping everything in `AppShell`

-- `index.tsx`, `tasks.tsx`, `timeline.tsx`, `projects.tsx`
+Routes: `__root.tsx` (AppShell layout), `index`, `tasks`, `timeline`, `projects`, `notes.$noteId`

 ### Database
 
-Schema lives in `src/main/db/schema.ts`. Migrations are in `src/main/db/migrations/`. The DB is created in Electron's `userData` directory as `adiuva.db`. On startup, `initDb()` runs non-destructive migrations (CREATE TABLE IF NOT EXISTS).

+LangGraph-based agentic system with pluggable LLM providers.
 
-**Orchestrator** (`orchestrator.ts`): Classifies user intent → routes to one of three specialist agents:
+### Orchestrator (`orchestrator.ts`)
-- **Project agent** — project-scoped Q&A with tools: `read_project_notes`, `add_task`, `get_summary`, `suggest_checkpoints`, `suggest_tasks`
-- **Knowledge agent** — cross-project semantic search via `vector_search_all`
-- **General agent** — workspace-wide `add_task`
 
-Tool-calling strategy differs by provider: OpenAI/Anthropic use LangChain `bindTools()` + ToolMessage loop (max 5 iterations); Copilot uses SDK-native tools (loop handled internally).
+Classifies user intent → routes to a specialist agent:
 
-**Streaming**: Orchestrator calls `sendStreamChunk(sender, token, done)` over IPC channel `'ai:stream'`. Renderer subscribes via `window.electronAI.onStreamChunk()` in `AIChatPanel.tsx`. `<tool_call>` blocks are filtered before sending to renderer.
+| Agent | Scope | Tools |
+|---|---|---|
+| Project | Project-scoped Q&A | `read_project_notes`, `add_task`, `get_summary`, `suggest_checkpoints`, `suggest_tasks` |
+| Knowledge | Cross-project search | `vector_search_all` |
+| General | Workspace-wide | `add_task` |
 
+All providers use LangChain `bindTools()` + ToolMessage loop (max 5 iterations).
+
+Also exports `dailyBrief()` for AI-generated daily summaries (`ai.dailyBrief` tRPC mutation).
+
+### Streaming
+
+`sendStreamChunk(sender, token, done)` over IPC `'ai:stream'`. Renderer subscribes via `window.electronAI.onStreamChunk()` in `AIChatPanel.tsx`. `<tool_call>` blocks are filtered before display.
+
+### Providers (`llm.ts`)
+
+| Provider | Model | Notes |
+|---|---|---|
+| OpenAI | `gpt-4o-mini` | Via LangChain |
+| Anthropic | `claude-sonnet-4-20250514` | Via LangChain |
+| Copilot | `ChatCopilot` wrapper | `copilot.ts` / `chat-copilot.ts` |
+
+All use `temperature: 0.3`, streaming enabled. Provider management in `provider.ts`.
+
+### Vector Embeddings (`db/vectordb.ts`)
 **Provider factory** (`llm.ts`): `gpt-4o-mini` (OpenAI), `claude-sonnet-4-20250514` (Anthropic), or ChatCopilot wrapper — all with `temperature: 0.3` and streaming enabled.
 
-**Token storage** (`token.ts`) — three-tier fallback:
+**Token storage** (`token.ts`) — two-tier fallback:
-1. keytar (OS keychain) — preferred, encrypted per-user
+1. electron-store + `safeStorage` — encrypted at rest (preferred)
-2. electron-store + `safeStorage` — encrypted at rest
+2. Plain electron-store — last resort (e.g. WSL with no keyring)
-3. Plain electron-store — WSL fallback
-
-Keytar service name is `'adiuva'`. Once keytar fails, `keytarFailed` flag skips it for the session.
 
 **AI approval pattern**: Tasks and checkpoints have `isAiSuggested` (bool) and `isApproved` (bool) columns. AI-suggested items appear in the UI pending user approval before being treated as real records.
 
 ### Vector Embeddings (`src/main/db/vectordb.ts`)
 
-LanceDB stored in `{userData}/vectors/`. Table schema: `{ id, projectId, content, vector }`. Vectors are 1536-dimensional (`text-embedding-3-small`). Embeddings use a priority chain: Copilot CLI token → OpenAI token.

-### Key Config Notes
+### AI Approval Pattern
 
-- Vite configs use `.mts` extension (not `.ts`) to avoid ESM/CJS conflicts with electron-forge's externalize-deps plugin
+Tasks and checkpoints have `isAiSuggested` + `isApproved` columns. AI suggestions appear pending user approval (dashed borders in UI).
-- `@/*` path alias resolves to `src/renderer/*` (TypeScript + Vite + shadcn/ui all share this alias)
+
-- shadcn/ui style: **new-york**, base color: **neutral**
+## Config Notes
-- Icons: **lucide-react** throughout — do not introduce other icon libraries
+
-- Tailwind 4 (not 3) — use CSS variable theming via `globals.css`, not `tailwind.config.js`
+- Vite configs use `.mts` (not `.ts`) — avoids ESM/CJS conflicts with electron-forge
-- Notes use Milkdown (`@milkdown/crepe`) as the markdown editor (`src/renderer/components/notes/MilkdownEditor.tsx`)
+- `@/*` path alias → `src/renderer/*` (TypeScript + Vite + shadcn/ui)
-- Routes: `index`, `tasks`, `timeline`, `projects`, `notes.$noteId` (note ID is a URL param)
+- **shadcn/ui**: new-york style, neutral base color
+- **Icons**: lucide-react only — do not introduce other icon libraries
+- **Tailwind 4** — CSS variable theming in `globals.css`, no `tailwind.config.js`

 ## Design Context
 
-### Users
+### Target User
-Freelancers and solo professionals managing their own client work — projects, tasks, notes, and timelines. They work alone and need a single workspace that keeps everything organized without the overhead of enterprise tools. The AI assistant is a force multiplier, helping them stay on top of their workload.

-### Brand Personality
+### Brand
-**Calm, intelligent, warm.** Adiuva is a thoughtful companion, not a flashy tool. It should feel like a well-organized desk — everything in its place, nothing competing for attention. The tone is confident and understated, never loud or gamified.
+**Calm, intelligent, warm.** Thoughtful companion, not flashy tool. Confident and understated, never loud or gamified.
 
-### Aesthetic Direction
+### Palette
-- **Visual tone**: Editorial, premium, content-first. Inspired by Notion's clean typography and warm neutrals, but with a distinct identity through the warm pinkish-white canvas and golden yellow accent
+
-- **Light mode**: Soft and warm — pinkish-white (`#f4edf3`) canvas, golden yellow (`#fbc881`) primary, slate blue-gray (`#8a8ea9`) secondary, dusty lavender borders (`#c8c3cd`)
+| | Canvas | Primary | Secondary | Borders |
-- **Dark mode**: Stark monochrome — near-black canvas (`#0c0c0c`), crisp white text, dark gray surfaces (`#323232`). No color accent; primary is pure white
+|---|---|---|---|---|
-- **Typography**: Geist (geometric sans-serif) at 400/500/600. Tight tracking on large headings (`-1px`). Body at `text-sm`, metadata at `text-xs`
+| **Light** | Pinkish-white `#f4edf3` | Golden yellow `#fbc881` | Slate blue-gray `#8a8ea9` | Dusty lavender `#c8c3cd` |
-- **Corners**: 10px base radius, consistently rounded. Chat elements use `rounded-2xl`
+| **Dark** | Near-black `#0c0c0c` | Pure white | — | Dark gray `#323232` |
-- **Signature effects**: Glassmorphism on AI inputs/floating chat (`backdrop-blur-xl`, transparency). Spring physics animations (stiffness 400, damping 30). Subtle scale-and-fade transitions
+
-- **Anti-references**: No gamification (badges, streaks, confetti). No corporate/enterprise density. Keep it mature and professional

 ### Design Principles
-
+1. **Clarity over cleverness** — Clear hierarchy, generous whitespace, comfortable density
-1. **Clarity over cleverness** — Every element should communicate its purpose instantly. Prefer clear hierarchy and whitespace over decorative flourish. Information density should feel comfortable, not cramped.
+2. **AI as quiet partner** — Deeply integrated but never intrusive. Dashed borders for pending AI items, Sparkles icon as AI marker
-
+3. **Warmth in restraint** — Warm palette feels approachable without being playful. Dark mode trades warmth for focus
-2. **AI as quiet partner** — The AI is deeply integrated (floating chat, suggestions) but never intrusive. AI-suggested items use dashed borders to signal "pending." The Sparkles icon is the consistent AI identity marker.
+4. **Motion with purpose** — Animations reinforce spatial relationships, never decorative
-
+5. **Confidence through consistency** — CSS variable tokens, shadcn/ui primitives, Geist font. Predictable, keyboard-first
-3. **Warmth in restraint** — The palette is deliberately warm (pinkish whites, golden yellows) to feel approachable without being playful. Dark mode trades warmth for focus. Let the content breathe.
-
-4. **Motion with purpose** — Spring physics and glassmorphism create a sense of physicality and depth. Animations should feel natural and responsive, never decorative or slow. Every transition should reinforce spatial relationships.

-5. **Confidence through consistency** — Use the established token system (CSS variables, shadcn/ui primitives, Geist font). The user should feel in control — predictable patterns, keyboard-first interactions, no surprises.

+# AI Refactor Plan — Adiuva Electron App
+
+> **Objective:** Transform the Electron app into a hybrid-first multi-agent client. The user controls where data is stored (local / cloud / sync), which AI provider to use (BYOK multi-provider), and which automations to run — either custom batch agents built with the LLM-powered Batch Builder, or pre-built plugins from the marketplace. All data access is opt-in, transparent, and auditable.
+>
+> **Backend:** Lives in a separate repository. See `../adiuva-api/BACKEND_PLAN.md` for the API contract and backend implementation guide.
+>
+> **Protocol:** Execute steps sequentially. Each step is atomic and committable. Mark `[x]` when done.
+
+---
+
+## Phase 0 — API Contracts & Types
+
+### Step 0.1 — Define backend API contract types
+- [ ] Create `src/shared/api-types.ts` with all interfaces the Electron app needs to communicate with the backend:
+  - `ExecutionPlan`, `PlanStep`, `PlanAction` (action types: `create_record`, `update_record`, `delete_record`, `index_document`, `send_notification`, `call_agent`)
+  - `ChatRequest` (message, context, execution_mode: `'direct'` | `'plan'`)
+  - `ChatResponse` (response, actions)
+  - `ChatContext` (user_profile, relevant_documents, recent_tasks, conversation_history)
+  - `AgentManifest` (name, description, permissions, schedule)
+  - `PermissionGrant` (plugin, permission type, resource path, granted_at)
+  - `BackupMetadata` (version, timestamp, checksum, chunk_count)
+  - `BillingTier` enum (`free`, `pro`, `power`, `team`)
+  - `AuthTokens` (access_token, refresh_token, expires_at)
+  - `UserProfile` (id, email, tier)
+- [ ] Create `src/shared/batch-types.ts` with all types for the batch builder and storage layer:
+  - `StorageTarget` — `'local'` | `'cloud'` | `'sync'` | `'none'`
+  - `ConnectorType` — `'imap'` | `'filesystem'` | `'calendar'` | `'api'` | `'gmail'` | `'gdrive'` | `'outlook'`
+  - `BatchActionType` — `'create_record'` | `'update_record'` | `'delete_record'` | `'index_document'` | `'send_notification'` | `'call_agent'`
+  - `BatchSource` — `{ connector: ConnectorType, config: Record<string, unknown> }`
+  - `BatchTrigger` — `{ type: 'cron' | 'event', schedule?: string, timezone?: string }`
+  - `BatchAnalysis` — `{ prompt: string, model_override?: string, output_schema?: object }`
+  - `BatchAction` — `{ type: BatchActionType, table?: string, mapping?: Record<string, string> }`
+  - `BatchStorage` — `{ records: StorageTarget, vectors: StorageTarget, raw_data: StorageTarget }`
+  - `BatchConfig` — full config object: `id`, `name`, `description`, `enabled`, `source`, `trigger`, `analysis`, `actions`, `storage`, `permissions`
+  - `BatchStatus` — `'idle'` | `'running'` | `'error'` | `'disabled'`
+  - `BatchRunResult` — `{ batchId, runAt, status, itemsProcessed, errors }`
+  - `PluginListing` — `{ id, name, description, author, version, rating, installs, category, permissions, price }`
+  - `InstalledPlugin` — `{ listing: PluginListing, installedAt, enabled, storageConfig: BatchStorage }`
+  - `DataSourceInfo` — `{ type: ConnectorType, label, recordCount, sizeBytes, storageTarget: StorageTarget }`
+  - `StorageStats` — `{ localUsedBytes, cloudUsedBytes, cloudLimitBytes, sources: DataSourceInfo[] }`
+- [ ] Update `tsconfig.json` paths if needed to include `src/shared/`
+- **Files:** `src/shared/api-types.ts`, `src/shared/batch-types.ts`, `tsconfig.json`
+- **Outcome:** Type-safe contracts for all backend communication and the batch/storage subsystem. Backend repo mirrors these as Pydantic schemas.

+
+## Phase 1 — LiteLLM Multi-Provider Client
+
+### Step 1.1 — Create unified LLM client wrapper
+- [ ] Create `src/main/llm/litellm-client.ts`:
+  - `LiteLLMClient` class with unified interface:
+    - `complete(messages: Message[], options?: CompletionOptions): Promise<CompletionResponse>`
+    - `stream(messages: Message[], options?: CompletionOptions): AsyncGenerator<string>`
+    - `embed(text: string): Promise<number[]>`
+  - `CompletionOptions`: model override, temperature, max_tokens, tools
+  - Provider-agnostic: internally maps to the correct provider SDK
+  - Fallback chain: tries primary provider, on failure tries secondary, logs each attempt
+  - Timeout handling: per-provider configurable timeouts
+- [ ] Create `src/main/llm/providers.ts`:
+  - `ProviderConfig` interface: name, apiKey, model, endpoint (for Ollama), timeout, isLocal
+  - `ProviderRegistry`: manages configured providers, persists to electron-store
+  - `getActiveProvider()`, `setActiveProvider(name)`, `addProvider(config)`, `removeProvider(name)`
+  - `getFallbackChain(): ProviderConfig[]`
+  - Supported providers: OpenAI, Anthropic, Google (Gemini), Mistral, Groq, Ollama (local)
+- [ ] Create `src/main/llm/embeddings.ts` (refactored):
+  - Support multiple embedding providers (OpenAI text-embedding-3-small, local ONNX with all-MiniLM-L6-v2)
+  - Auto-select: use local ONNX if available, fall back to API
+  - Same `embedText(text): Promise<number[]>` interface
+- **Files:** `src/main/llm/litellm-client.ts`, `src/main/llm/providers.ts`, `src/main/llm/embeddings.ts`
+- **Outcome:** Single LLM interface that all local components use. Supports 6+ providers with fallback.
+
+### Step 1.2 — Migrate existing AI code to use new LLM client
+- [ ] Update `src/main/ai/orchestrator.ts`:
+  - Replace direct `getLLM()` calls with `LiteLLMClient.complete()` / `LiteLLMClient.stream()`
+  - Keep local orchestration working with the new client (backend delegation comes in Phase 3)
+- [ ] Update `src/main/ai/llm.ts`:
+  - Deprecate. Redirect `getLLM()` to instantiate via `LiteLLMClient` as a thin compatibility shim
+- [ ] Update `src/main/ai/embeddings.ts` to delegate to `src/main/llm/embeddings.ts`
+- [ ] Update `src/main/ai/token.ts`:
+  - Add `listStoredProviders(): Promise<string[]>` to enumerate which providers have tokens
+- [ ] Ensure all existing AI features (chat, daily brief, tool calling) continue to work
+- **Files:** `src/main/ai/orchestrator.ts`, `src/main/ai/llm.ts`, `src/main/ai/embeddings.ts`, `src/main/ai/token.ts`
+- **Outcome:** Existing AI features work identically but go through the new unified LLM client.
+
+---
+
+## Phase 2 — Local Plugin System & Batch Agents
+
+### Step 2.1 — Create plugin manifest system and permission manager
+- [ ] Create `src/main/permissions/manifest-validator.ts`:
+  - `PluginManifest` interface: `name`, `description`, `version`, `permissions: PermissionRequest[]`, `schedule?: string` (cron), `entryPoint: string`
+  - `PermissionRequest`: `type` (read_folder, read_email, read_calendar, read_browser_history), `resource?: string` (path, account), `reason: string`
+  - `validateManifest(manifest): ValidationResult` — validates structure, checks for dangerous permissions
+- [ ] Create `src/main/permissions/permission-manager.ts`:
+  - `PermissionManager` class (singleton):
+    - `grantPermission(pluginName, permission): void` — persists to SQLite
+    - `revokePermission(pluginName, permission): void`
+    - `checkPermission(pluginName, permission): boolean`
+    - `getPluginPermissions(pluginName): PermissionGrant[]`
+    - `getAllGrants(): PermissionGrant[]`
+    - `logAccess(pluginName, permission, resource, timestamp): void` — activity log
+    - `getActivityLog(pluginName?, limit?): ActivityLogEntry[]`
+  - Permission grants stored in a new `plugin_permissions` SQLite table
+  - Activity log stored in a new `plugin_activity_log` SQLite table
+- [ ] Add `plugin_permissions` and `plugin_activity_log` tables to `src/main/db/schema.ts`
+- [ ] Generate and apply migration
+- **Files:** `src/main/permissions/manifest-validator.ts`, `src/main/permissions/permission-manager.ts`, `src/main/db/schema.ts`, `src/main/db/migrations/`
+- **Outcome:** Granular, opt-in permission system for plugins. Every access is logged.
+
+### Step 2.2 — Create worker pool and batch runner
+- [ ] Create `src/main/workers/worker-pool.ts`:
+  - `WorkerPool` class:
+    - Manages a pool of Node.js `worker_threads`
+    - `runPlugin(manifest, context): Promise<PluginResult>` — spawns or reuses a worker, sends manifest + context, receives result
+    - Worker lifecycle: create, send message, receive result, terminate on timeout
+    - Max concurrent workers: configurable (default 4)
+    - Error isolation: worker crash doesn't affect main process
+- [ ] Create `src/main/workers/batch-runner.ts`:
+  - `BatchRunner` class:
+    - `registerPlugin(manifest): void` — validates manifest, stores in registry
+    - `startScheduler(): void` — cron-based scheduler using `node-cron` or simple setInterval
+    - `runPlugin(name, triggerContext?): Promise<PluginResult>` — manual trigger
+    - `stopAll(): void` — graceful shutdown of all scheduled plugins
+    - Scheduler checks permissions before each run; skips if revoked
+    - Results logged to activity log
+- [ ] Create `src/main/workers/plugin-worker.ts`:
+  - Worker thread entry point
+  - Receives plugin config + context via `parentPort.on('message')`
+  - Dynamically imports the plugin entry point
+  - Executes `run(context)` with sandboxed access (only permitted resources)
+  - Posts result back via `parentPort.postMessage()`
+- **Files:** `src/main/workers/worker-pool.ts`, `src/main/workers/batch-runner.ts`, `src/main/workers/plugin-worker.ts`
+- **Outcome:** Isolated plugin execution environment with scheduling, permissions enforcement, and error isolation.
+
+### Step 2.3 — Implement batch agent plugins
+- [ ] Create `src/plugins/email-scanner.ts`:
+  - Manifest: requires `read_email` permission
+  - Connects to IMAP via `imapflow` (account configured in settings)
+  - Scans for new emails since last run
+  - Uses `LiteLLMClient` to classify each email (has actionable task? extract title, priority, description)
+  - Returns extracted task metadata (never raw email content) for execution via backend or local playbook
+- [ ] Create `src/plugins/file-watcher.ts`:
+  - Manifest: requires `read_folder` permission for each watched path
+  - Uses `chokidar` to watch approved directories
+  - On new/modified file: reads content, generates embedding, upserts into vector store
+  - Supports: .txt, .md, .pdf (text extraction), .docx (basic extraction)
+- [ ] Create `src/plugins/calendar-sync.ts`:
+  - Manifest: requires `read_calendar` permission
+  - Parses ICS files or connects to CalDAV endpoint
+  - Detects scheduling conflicts
+  - Suggests reorganizations via LLM analysis
+  - Returns calendar events + conflict reports
+- [ ] Create `src/plugins/browser-agent.ts`:
+  - Manifest: requires `read_browser_history` permission (explicit opt-in)
+  - Reads browser bookmarks and history from known browser paths (Chrome, Firefox, Edge)
+  - Indexes relevant entries into vector store
+  - Privacy-first: only indexes URLs and titles, not page content
+- **Files:** `src/plugins/email-scanner.ts`, `src/plugins/file-watcher.ts`, `src/plugins/calendar-sync.ts`, `src/plugins/browser-agent.ts`
+- **Outcome:** Four local batch agents running as isolated worker threads, using LiteLLM for analysis.
+
+---
+
+## Phase 3 — Backend Integration
+
+### Step 3.1 — Create backend HTTP/WebSocket client
+- [ ] Create `src/main/api/backend-client.ts`:
+  - `BackendClient` class:
+    - `baseUrl` configurable (default: production cloud URL, overridable for dev)
+    - `setAuthToken(jwt: string): void`
+    - `chat(request: ChatRequest): Promise<ChatResponse>` — POST /api/v1/chat
+    - `chatStream(request: ChatRequest): AsyncGenerator<string>` — WebSocket /api/v1/chat/stream
+    - `getPlaybooks(): Promise<ExecutionPlan[]>` — GET /api/v1/plans/playbook
+    - `uploadBackup(blob: Buffer, metadata: BackupMetadata): Promise<void>` — PUT /api/v1/backup
+    - `downloadBackup(): Promise<{ blob: Buffer, metadata: BackupMetadata }>` — GET /api/v1/backup
+    - Automatic retry with exponential backoff (max 3 attempts)
+    - Offline detection: returns cached playbook responses when offline
+  - `isOnline(): boolean` — connectivity check
+- [ ] Create `src/main/api/plan-runner.ts`:
+  - `PlanRunner` class:
+    - `execute(plan: ExecutionPlan): Promise<PlanResult>` — executes plan steps locally
+    - Step handlers: `create_record` (inserts into SQLite), `update_record`, `delete_record`, `index_document` (upserts into vector store), `send_notification` (Electron notification API)
+    - Each step logs to activity log
+    - Supports `data_from_step` references (pipeline execution)
+    - Validates plan structure before execution
+- **Files:** `src/main/api/backend-client.ts`, `src/main/api/plan-runner.ts`
+- **Outcome:** Electron can communicate with the cloud backend and execute returned plans locally.
+
+### Step 3.2 — Refactor orchestrator to delegate to backend
+- [ ] Update `src/main/ai/orchestrator.ts`:
+  - When online: forward chat requests to backend via `BackendClient.chatStream()`
+  - Build `ChatRequest` from local context: query SQLite for user profile, relevant documents (from vector store), recent tasks, conversation history
+  - Stream backend response tokens to renderer via existing `ai:stream` IPC channel
+  - Execute any returned actions via `PlanRunner`
+  - When offline: fall back to local orchestration (existing LangGraph pipeline) with degraded capabilities
+  - Remove direct agent logic (project agent, knowledge agent, general agent tool definitions) — these now live on the backend
+  - Keep `buildProjectContext()` and `buildGlobalContext()` as context builders for the request payload
+- [ ] Update `src/main/router/index.ts` `ai` sub-router:
+  - `chat` mutation: call refactored orchestrator (which now delegates to backend)
+  - Add `getPlaybooks` query: fetches cached playbooks
+  - Keep `dailyBrief` mutation: sends daily brief request to backend
+- [ ] Add IPC handler for plan execution results
+- **Files:** `src/main/ai/orchestrator.ts`, `src/main/router/index.ts`, `src/main/ipc.ts`
+- **Outcome:** Chat intelligence lives on the backend; Electron is the execution layer.
+
+### Step 3.3 — Implement Shared Memory (three-tier local memory)
+- [ ] Create `src/main/database/shared-memory.ts`:
+  - **Short-term memory**: In-memory conversation buffer
+    - `ConversationBuffer` class: stores last N messages per session
+    - `addMessage(sessionId, role, content)`, `getHistory(sessionId, limit?) -> Message[]`
+    - Cleared on session end
+  - **Long-term KV store**: SQLite-backed key-value store
+    - New `agent_memory` table: `id`, `namespace` (agent name), `key`, `value` (JSON text), `updated_at`
+    - `AgentMemoryStore` class: `get(namespace, key)`, `set(namespace, key, value)`, `delete(namespace, key)`, `listKeys(namespace)`
+    - Used by agents to persist learned facts, user preferences
+  - **Vector store**: Already exists (LanceDB). Enhance with:
+    - Multi-collection support: separate tables for notes, emails, files, calendar
+    - `searchByCollection(collection, query, limit) -> SearchResult[]`
+- [ ] Add `agent_memory` table to `src/main/db/schema.ts`
+- [ ] Generate migration
+- **Files:** `src/main/database/shared-memory.ts`, `src/main/db/schema.ts`, `src/main/db/migrations/`
+- **Outcome:** Three-tier memory system supporting short-term conversation, long-term agent facts, and semantic search.
+
+---
+
+## Phase 4 — Security: E2E Backup & Offline Mode
+
+### Step 4.1 — Implement E2E encrypted backup
+- [ ] Create `src/main/backup/e2e-crypto.ts`:
+  - `generatePassphrase(): string` — BIP39-compatible 12-word recovery phrase
+  - `deriveKey(passphrase: string, salt: Buffer): Promise<Buffer>` — Argon2id key derivation (time cost 3, memory 64MB, parallelism 1)
+  - `encrypt(data: Buffer, key: Buffer): { ciphertext: Buffer, iv: Buffer, authTag: Buffer }` — AES-256-GCM
+  - `decrypt(ciphertext: Buffer, key: Buffer, iv: Buffer, authTag: Buffer): Buffer`
+  - Uses `node:crypto` for AES and `argon2` npm package for key derivation
+- [ ] Create `src/main/backup/backup-manager.ts`:
+  - `BackupManager` class:
+    - `createBackup(passphrase: string): Promise<BackupBlob>` — Exports SQLite DB, encrypts, returns blob + metadata
+    - `restoreBackup(blob: Buffer, passphrase: string): Promise<void>` — Decrypts blob, replaces local DB, re-initializes
+    - `uploadBackup(passphrase: string): Promise<void>` — Creates backup, uploads via `BackendClient`
+    - `downloadAndRestore(passphrase: string): Promise<void>` — Downloads from backend, decrypts, restores
+    - Incremental backup: chunks DB into segments, encrypts each separately, tracks content hashes to skip unchanged chunks
+    - Metadata header: version, timestamp, checksum (SHA-256 of plaintext), chunk count
+- **Files:** `src/main/backup/e2e-crypto.ts`, `src/main/backup/backup-manager.ts`
+- **Outcome:** User data never leaves the device unencrypted. Backend stores only opaque blobs.
+
+### Step 4.2 — Implement offline sync queue
+- [ ] Create `src/main/backup/sync-queue.ts`:
+  - `SyncQueue` class:
+    - `enqueue(action: QueuedAction): void` — Adds action to persistent queue (SQLite table `sync_queue`)
+    - `processQueue(): Promise<void>` — Processes queued actions in FIFO order when online
+    - `getQueueSize(): number`
+    - `clearQueue(): void`
+    - Conflict resolution: last-write-wins with timestamps
+  - New `sync_queue` table: `id`, `action_type`, `payload` (JSON), `created_at`, `status` (pending/processing/failed), `retry_count`, `last_error`
+  - Auto-drain: watches connectivity, starts processing when online
+  - Failed actions: retry up to 3 times with exponential backoff, then mark as `failed` for user review
+- [ ] Add `sync_queue` table to schema
+- [ ] Integrate with `BackendClient`: when offline, chat/backup calls enqueue instead of failing
+- **Files:** `src/main/backup/sync-queue.ts`, `src/main/db/schema.ts`, `src/main/api/backend-client.ts`
+- **Outcome:** App works offline; queued actions sync automatically when connectivity returns.
+
+---
+
+## Phase 5 — Auth Integration & Database Encryption
+
+### Step 5.1 — Integrate auth into Electron app
+- [ ] Create `src/main/auth/auth-manager.ts`:
+  - `AuthManager` class:
+    - `login(email, password): Promise<void>` — Calls backend POST /api/v1/auth/login, stores JWT in secure storage (via token.ts)
+    - `register(email, password): Promise<void>` — Calls POST /api/v1/auth/register
+    - `logout(): void` — Clears stored JWT
+    - `getToken(): string | null` — Returns current JWT
+    - `refreshToken(): Promise<void>` — Auto-refresh before expiry
+    - `isAuthenticated(): boolean`
+    - `getCurrentTier(): BillingTier`
+  - Auto-refresh: checks token expiry every 5 minutes, refreshes if < 10 minutes remaining
+- [ ] Add tRPC procedures: `auth.login`, `auth.register`, `auth.logout`, `auth.status`, `auth.tier`
+- [ ] Wire `BackendClient` to use `AuthManager.getToken()` for all requests
+- **Files:** `src/main/auth/auth-manager.ts`, `src/main/router/index.ts`, `src/main/api/backend-client.ts`
+- **Outcome:** Electron app has full auth flow; backend requests are authenticated.
+
+### Step 5.2 — Migrate from better-sqlite3 to SQLCipher
+- [ ] Add `@journeyapps/sqlcipher` to dependencies (replaces `better-sqlite3`)
+- [ ] Update `src/main/db/index.ts`:
+  - Replace `better-sqlite3` import with `@journeyapps/sqlcipher`
+  - On first launch: derive DB key from OS keychain or prompt user
+  - `initDb(password)`: opens DB with `PRAGMA key = 'password'`
+  - Migration path for existing unencrypted DBs: detect → export → create encrypted → import → delete old
+  - WAL mode still enabled after keying
+- [ ] Update `src/main/index.ts`: pass password to `initDb()`
+- [ ] Test that all existing Drizzle operations work with SQLCipher
+- **Files:** `package.json`, `src/main/db/index.ts`, `src/main/index.ts`
+- **Outcome:** All local data encrypted at rest with SQLCipher.
+
+---
+
+## Phase 6 — Renderer UI Updates
+
+> **Navigation model:** The app has a sidebar with top-level routes matching the pages below. Each page is a full-screen view. Shared hooks live in `src/renderer/hooks/`. All data access goes through tRPC procedures — no direct IPC calls from components.
+
+### Step 6.1 — Restructure app shell and routing
+- [ ] Update `src/renderer/App.tsx`:
+  - Define top-level routes: `/chat`, `/batch-builder`, `/plugins`, `/data-manager`, `/settings`, `/activity`
+  - Add sidebar navigation with icons and labels for each route
+  - Persist last active route in electron-store
+- [ ] Create `src/renderer/hooks/useProvider.ts`:

+  - Backed by tRPC `provider.*` procedures (to be added in Phase 1)
+- [ ] Create `src/renderer/hooks/useStorage.ts`:
+  - `useStorage()` — returns `StorageStats`, `setStorageTarget(source, target)`, `migrateData(source, from, to)`
+  - Backed by tRPC `storage.*` procedures (to be added in Phase 2)
+- **Files:** `src/renderer/App.tsx`, `src/renderer/hooks/useProvider.ts`, `src/renderer/hooks/useStorage.ts`
+- **Outcome:** App shell with all top-level routes and shared data hooks.
+

+- [ ] Create `src/renderer/components/chat/ChatWindow.tsx`:
+  - Message list rendering `MessageBubble` for each entry
+  - Input bar with send button and attachment support
+  - Handles streaming tokens from `useChat` hook
+  - Plan approval UI inline: expandable plan steps with approve/reject per-step
+  - Error states: offline, auth expired, rate limited, server error (distinct UI for each)
+- [ ] Create `src/renderer/components/chat/MessageBubble.tsx`:
+  - Renders user / assistant / system messages
+  - Supports markdown rendering for assistant messages
+  - Shows tool-call indicators when the agent uses a tool
+  - Timestamp and copy-to-clipboard action
+- [ ] Create `src/renderer/components/chat/ContextPanel.tsx`:
+  - Shows what context the agent used for the last response: matched documents, recent tasks, memory entries
+  - Each context item links to its source (note, file, batch result)
+  - Collapsible, persists open/closed state
+- [ ] Create `src/renderer/hooks/useChat.ts`:
+  - `useChat(sessionId)` — message list, `sendMessage()`, streaming state, connection mode (`'backend'` | `'local'`)
+  - Automatically falls back to local orchestrator when offline
+  - Exposes `approveStep(stepId)` / `rejectStep(stepId)` for plan execution
+- **Files:** `src/renderer/pages/ChatPage.tsx`, `src/renderer/components/chat/ChatWindow.tsx`, `src/renderer/components/chat/MessageBubble.tsx`, `src/renderer/components/chat/ContextPanel.tsx`, `src/renderer/hooks/useChat.ts`
+- **Outcome:** Full chat UI with context transparency, plan approval, and seamless online/offline fallback.
+
+### Step 6.3 — BatchBuilderPage
+- [ ] Create `src/renderer/pages/BatchBuilderPage.tsx`:
+  - Two views: **Active Batches** list (default) and **Create New Batch** wizard
+  - Active list renders `BatchCard` for each active batch config
+  - "Create" button opens the wizard
+- [ ] Create `src/renderer/components/batch-builder/NaturalLanguageInput.tsx`:
+  - Textarea where the user describes the batch in plain language
+  - "Generate" button calls `useBatchBuilder().generate(description)`
+  - Loading skeleton while the LLM generates the config
+- [ ] Create `src/renderer/components/batch-builder/ConfigPreview.tsx`:
+  - Shows the generated `BatchConfig` as an editable form (not raw JSON)
+  - Sections: Source, Trigger, Analysis, Actions, Storage — each collapsible
+  - Inline editing for every field (prompt textarea, cron expression with human-readable label, mapping table)
+  - "Edit raw JSON" toggle for power users
+- [ ] Create `src/renderer/components/batch-builder/ConnectorPicker.tsx`:
+  - Dropdown of available connector types (IMAP, Filesystem, Gmail, GDrive, Outlook, Calendar, Generic API)
+  - When selected, shows connector-specific config fields (e.g. IMAP: host, folder, filter_from; Filesystem: path picker)
+  - OAuth connectors show "Connect account" button that opens the OAuth flow
+- [ ] Create `src/renderer/components/batch-builder/StoragePicker.tsx`:
+  - Three-way toggle per storage dimension: **Local** / **Cloud** / **Sync** / **None**
+  - Dimensions: Records, Vectors, Raw data
+  - Shows storage impact estimate per option
+  - Disabled options grayed out with tier tooltip if current tier doesn't support cloud
+- [ ] Create `src/renderer/components/batch-builder/SchedulePicker.tsx`:
+  - Mode toggle: **Cron** (with human-readable label, e.g. "Every day at 08:00") / **Event** (on new data from connector)
+  - Timezone selector (defaults to system timezone)
+  - Visual cron builder for non-technical users (with raw cron input fallback)
+- [ ] Create `src/renderer/components/batch-builder/BatchCard.tsx`:
+  - Shows batch name, connector icon, last run time, next run time, status badge (`idle` / `running` / `error` / `disabled`)
+  - Actions: Run now, Edit, Disable/Enable, Delete
+  - Expandable to show last run summary (items processed, errors)
+- [ ] Create `src/renderer/components/batch-builder/BatchTestRunner.tsx`:
+  - "Dry Run" panel: picks one real item from the source, runs the full analysis pipeline, shows output without saving
+  - Shows LLM output, action mapping preview, what would be stored and where
+  - Pass/Fail indicator with detailed error on failure
+- [ ] Create `src/renderer/hooks/useBatchBuilder.ts`:
+  - `useBatchBuilder()` — `generate(description): Promise<BatchConfig>`, `validate(config)`, `save(config)`, `activate(id)`, `deactivate(id)`, `runNow(id)`, `dryRun(id)`, `delete(id)`, list of saved configs with live status
+  - Backed by tRPC `batch.*` procedures
+- **Files:** `src/renderer/pages/BatchBuilderPage.tsx`, `src/renderer/components/batch-builder/{NaturalLanguageInput,ConfigPreview,ConnectorPicker,StoragePicker,SchedulePicker,BatchCard,BatchTestRunner}.tsx`, `src/renderer/hooks/useBatchBuilder.ts`
+- **Outcome:** Full Batch Builder UI — users can describe a batch in natural language, review/edit the generated config, dry-run it, and activate it with a single flow.
+
+### Step 6.4 — PluginStorePage
+- [ ] Create `src/renderer/pages/PluginStorePage.tsx`:
+  - Two tabs: **Marketplace** (browse available plugins) and **Installed** (manage installed plugins)
+  - Marketplace: search bar, category filter chips, grid of plugin cards sorted by rating/installs
+  - Installed: list of `InstalledPlugin` entries with enable/disable toggles and settings links
+- [ ] Create plugin card component (inline or shared `common/`):
+  - Shows name, author, description, rating (stars), install count, category badge, price/free badge
+  - "Install" button → triggers permission request dialog → installs plugin
+  - "Settings" button (installed) → opens plugin-specific config drawer
+- [ ] Plugin install flow:
+  - On install click: fetch plugin manifest from backend
+  - Show `PermissionDialog` with the permissions the plugin requires
+  - On approve: call tRPC `plugins.install(id)`, download and register the plugin worker
+  - Show `StoragePicker` for the plugin's data (what goes local/cloud/sync)
+- **Files:** `src/renderer/pages/PluginStorePage.tsx`
+- **Outcome:** Users can discover and install pre-built plugins from the marketplace with full permission visibility.
+
+### Step 6.5 — DataManagerPage
+- [ ] Create `src/renderer/pages/DataManagerPage.tsx`:
+  - Top section: `StorageOverview` dashboard
+  - Below: list of `DataSourceCard` for each active data source (one card per connector/plugin)
+  - "Migrate" button opens `MigrationWizard`
+- [ ] Create `src/renderer/components/data-manager/StorageOverview.tsx`:
+  - Visual breakdown: local disk used vs. cloud used vs. cloud limit
+  - Per-category breakdown (emails, files, notes, calendar, vectors)
+  - Tier upgrade CTA if approaching cloud limit
+- [ ] Create `src/renderer/components/data-manager/DataSourceCard.tsx`:
+  - Card per data source (e.g. "Gmail Scanner", "Documenti/Fatture watcher")
+  - Shows record count, size, last sync time
+  - Inline `StoragePicker` toggle for that source (where its data lives)
+  - "Clear local cache" / "Delete all data" actions with confirmation
+- [ ] Create `src/renderer/components/data-manager/MigrationWizard.tsx`:
+  - Step wizard: select source → select direction (local → cloud or cloud → local) → confirm
+  - Shows estimated data size and time
+  - Progress indicator during migration
+  - Rolls back on error
+- **Files:** `src/renderer/pages/DataManagerPage.tsx`, `src/renderer/components/data-manager/{StorageOverview,DataSourceCard,MigrationWizard}.tsx`
+- **Outcome:** Users have full visibility and control over where every piece of their data lives.
+
+### Step 6.6 — ActivityLogPage
+- [ ] Create `src/renderer/pages/ActivityLogPage.tsx`:
+  - Full-page filterable table of all batch/plugin activity entries
+  - Columns: timestamp, source (batch name / plugin name), action type, data accessed, storage destination, status
+  - Filters: source, date range, action type, status (success/error)
+  - Row expand: shows full detail — which records were created/updated, which files were read, LLM calls made
+  - Export as CSV button
+- **Files:** `src/renderer/pages/ActivityLogPage.tsx`
+- **Outcome:** Complete transparency log so users can audit exactly what each agent did and when.
+
+### Step 6.7 — SettingsPage (multi-provider, auth, backup, embeddings)
+- [ ] Create `src/renderer/pages/SettingsPage.tsx` with tabbed sections:
+  - **AI Providers** tab:
+    - List of configured providers with status badge (active / inactive / error)
+    - Add provider form: name dropdown (OpenAI, Anthropic, Google, Mistral, Groq, Ollama), API key input, model selection, endpoint (for Ollama)
+    - Set primary provider and fallback chain
+    - Test connection button per provider
+    - Separate "Embeddings provider" section: provider + model for embeddings (OpenAI, Cohere, Voyage, Mistral Embed)
+    - Info callout: "Text sent to the embeddings provider to generate vectors — make sure you trust this provider with your data"
+  - **Account & Billing** tab:
+    - Login/register form (when not authenticated)
+    - Current tier display with feature list and upgrade CTA
+    - Usage indicators (batch count, cloud storage used)
+    - Logout button
+  - **Backup & Sync** tab:
+    - Recovery passphrase: generate new / view existing (masked, reveal on click)
+    - Manual backup trigger with last backup timestamp
+    - Auto-backup schedule toggle + interval picker
+    - Backup history table (timestamp, size, restore button)
+  - **Permissions** tab:
+    - Table of all active permission grants (plugin/batch, permission type, resource, granted date)
+    - Revoke button per grant
+    - Links to ActivityLogPage for per-source audit
+- [ ] Create `src/renderer/components/common/ProviderSelector.tsx`:
+  - Reusable dropdown that lists configured LLM providers
+  - Used in BatchBuilder (model_override field) and Settings
+- [ ] Create `src/renderer/components/common/PermissionDialog.tsx`:
+  - Modal triggered when a plugin/batch requests new permissions
+  - Lists each requested permission with its reason and resource path
+  - Per-permission approve/deny toggles (deny is default)
+  - Shows plugin/batch manifest info (name, description, version)
+  - "Approve selected" confirms; "Deny all" closes without granting
+- **Files:** `src/renderer/pages/SettingsPage.tsx`, `src/renderer/components/common/PermissionDialog.tsx`, `src/renderer/components/common/ProviderSelector.tsx`
+- **Outcome:** Centralised settings covering providers, embeddings, auth, backup, and permissions.
+
+---
+
+## Phase 7 — Cleanup & Hardening
+
+### Step 7.1 — Remove deprecated AI code
+- [ ] Delete `src/main/ai/copilot.ts` (Copilot SDK replaced by LiteLLM)
+- [ ] Delete `src/main/ai/chat-copilot.ts` (LangChain adapter no longer needed)
+- [ ] Delete or archive `src/main/ai/llm.ts` (replaced by `src/main/llm/litellm-client.ts`)
+- [ ] Remove `@github/copilot-sdk`, `@langchain/langgraph` from dependencies (if unused)
+- [ ] Clean up `src/main/ai/provider.ts`: simplify to delegate to `src/main/llm/providers.ts`
+- [ ] Remove `currentSender` module-level mutable state from orchestrator (proper context passing)
+- [ ] Update `src/main/index.ts` startup: remove `import './ai/copilot'`, add `BatchRunner.startScheduler()`, add `AuthManager` init
+- **Files:** Multiple files under `src/main/ai/`, `package.json`, `src/main/index.ts`
+- **Outcome:** No dead code; clean, maintainable codebase.
+
+### Step 7.2 — Add error handling and logging
+- [ ] Implement structured logging in main process:
+  - Log levels: debug, info, warn, error
+  - Log destinations: console (dev), file (production, rotated)
+  - Correlation IDs for request tracing across IPC → backend → response
+- [ ] Add error boundaries in renderer:
+  - Per-route error boundaries
+  - AI chat error boundary (graceful degradation)
+  - Plugin error boundary (shows which plugin failed)
+- **Files:** `src/main/utils/logger.ts` (new), `src/renderer/components/ErrorBoundary.tsx` (new)
+- **Outcome:** Production-ready error handling and observability.
+
+### Step 7.3 — Electron integration tests
+- [ ] Test BackendClient with mocked HTTP responses
+- [ ] Test PlanRunner with sample execution plans
+- [ ] Test SyncQueue offline → online transition
+- [ ] Test BackupManager encrypt → decrypt round-trip
+- [ ] Test PermissionManager grant → check → revoke cycle
+- **Files:** `src/main/__tests__/` (new test directory)
+- **Outcome:** Confidence that all Electron-side components work correctly.
+
+---
+
+## New Dependencies (package.json)
+
+| Package | Purpose |
+|---|---|
+| `@journeyapps/sqlcipher` | Encrypted SQLite (replaces `better-sqlite3`) |
+| `argon2` | Key derivation for E2E backup |
+| `node-cron` | Batch agent scheduling |
+| `chokidar` | File watching (FileWatcher plugin) |
+| `imapflow` | IMAP client (IMAP connector) |
+| `googleapis` | Gmail + GDrive OAuth connectors |
+| `lancedb` | Local vector store |
+| `onnxruntime-node` | Local embeddings (optional, future) |
+
+---
+
+## Execution Notes
+
+- **Each step is independently committable** and produces working code.
+- **Phases 1-2** (LLM client + plugins) are independent of the backend — can start immediately.
+- **Phase 3** (backend integration) requires the backend repo to have the `/api/v1/chat` endpoint ready.
+- **Phase 5.2** (SQLCipher) is intentionally late to avoid encryption overhead during active schema changes.
+- **The existing app continues to work** throughout the migration. Local orchestration is preserved until backend is ready (Step 3.2).
+- **One step at a time.** Implement one numbered step per session. When the step is fully done, mark all its checkboxes as `[x]` in this file and commit with message `step N complete: <outcome line>`.
