+
+## Architecture
+
+Adiuva is a local-first Electron desktop app. The three processes communicate via a custom tRPC v11 ↔ IPC bridge (the public `electron-trpc` package is incompatible with tRPC v11).
+
+```
+Renderer (React 19)  ──ipcLink──►  Preload (contextBridge)  ──IPC──►  Main (tRPC router + SQLite)
+```
+
+### Main Process (`src/main/`)
+
+Owns the database and all business logic.
+
+| File | Purpose |
+|---|---|
+| `index.ts` | Window creation, app lifecycle |
+| `ipc.ts` | Bridges `ipcMain` to tRPC procedures |
+| `router/index.ts` | All tRPC sub-routers merged into `appRouter` |
+| `db/index.ts` | Drizzle + better-sqlite3, WAL mode, singleton `getDb()` |
+| `db/schema.ts` | Table definitions: clients, projects, tasks, checkpoints, notes, taskComments |
+| `db/vectordb.ts` | LanceDB vector store for note embeddings |
+| `store.ts` | electron-store for persistent UI settings |
+
+### Preload (`src/preload/trpc.ts`)
+
+Exposes `window.electronTRPC` with `sendMessage()` / `onMessage()`.
+
+### Renderer (`src/renderer/`)
+
+React 19 — never accesses Node APIs directly. All data through `trpc.*.useQuery()` / `trpc.*.useMutation()`.
+
+| File | Purpose |
+|---|---|
+| `lib/ipcLink.ts` | Custom TRPCLink routing through `window.electronTRPC` |
+| `lib/trpc.ts` | `createTRPCReact<AppRouter>()` typed client |
+| `index.tsx` | QueryClient + tRPC + Router providers |
+
+### Routing
+
+File-based via TanStack Router (`tsr.config.json` at root). Route tree auto-generated at `routeTree.gen.ts`.
+
+Routes: `__root.tsx` (AppShell layout), `index`, `tasks`, `timeline`, `projects`, `notes.$noteId`
+
+### tRPC Routers
+
+`health`, `settings`, `clients`, `projects`, `tasks`, `checkpoints`, `notes`, `taskComments`, `ai`
+
+### Database
+
+Schema in `src/main/db/schema.ts`, migrations in `src/main/db/migrations/`. DB created in Electron's `userData` as `adiuva.db`. On startup, `initDb()` runs non-destructive migrations.
+
+To add a table/column: edit `schema.ts` → `drizzle-kit generate` → `drizzle-kit push` (dev) or commit the migration.
+
+### Adding a Feature (end-to-end)
+
+1. **Schema** — `src/main/db/schema.ts`
+2. **Router** — Add sub-router in `src/main/router/index.ts`, merge into `appRouter`
+3. **Types** — Flow automatically via `AppRouter` export
+4. **UI** — Components in `src/renderer/components/<feature>/`, data via `trpc.*.useQuery()`
+
+## AI Subsystem (`src/main/ai/`)
+
+LangGraph-based agentic system with pluggable LLM providers.
+
+### Orchestrator (`orchestrator.ts`)
+
+Classifies user intent → routes to a specialist agent:
+
+| 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`.
+
+### Token Storage (`token.ts`)
+
+Three-tier fallback (keytar service name: `'adiuva'`):
+1. keytar (OS keychain) — preferred; `keytarFailed` flag skips after first failure
+2. electron-store + `safeStorage` — encrypted at rest
+3. Plain electron-store — WSL fallback
+
+### Vector Embeddings (`db/vectordb.ts`)
+
+LanceDB in `{userData}/vectors/`. Schema: `{ id, projectId, content, vector }` (1536-dim, `text-embedding-3-small` via `embeddings.ts`). Embedding priority: Copilot CLI token → OpenAI token.
+
+- `upsertNoteEmbedding()` on note create/update (fire-and-forget)
+- `migrateNotesIfNeeded()` backfills on first startup
+- `searchNotes(query, limit=5)` used by Knowledge agent
+
+### AI Approval Pattern
+
+Tasks and checkpoints have `isAiSuggested` + `isApproved` columns. AI suggestions appear pending user approval (dashed borders in UI).
+
+## Config Notes
+
+- Vite configs use `.mts` (not `.ts`) — avoids ESM/CJS conflicts with electron-forge
+- `@/*` path alias → `src/renderer/*` (TypeScript + Vite + shadcn/ui)
+- **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`
+- **Notes editor**: Milkdown (`@milkdown/crepe`) at `src/renderer/components/notes/MilkdownEditor.tsx`
+
+## Design Context
+
+### Target User
+Freelancers and solo professionals managing client work (projects, tasks, notes, timelines). Single workspace, no enterprise overhead. AI as force multiplier.
+
+### Brand
+**Calm, intelligent, warm.** Thoughtful companion, not flashy tool. Confident and understated, never loud or gamified.
+
+### Palette
+
+| | Canvas | Primary | Secondary | Borders |
+|---|---|---|---|---|
+| **Light** | Pinkish-white `#f4edf3` | Golden yellow `#fbc881` | Slate blue-gray `#8a8ea9` | Dusty lavender `#c8c3cd` |
+| **Dark** | Near-black `#0c0c0c` | Pure white | — | Dark gray `#323232` |
+
+### Typography
+Geist sans-serif, weights 400/500/600. Tight tracking (`-1px`) on headings. Body `text-sm`, metadata `text-xs`.
+
+### Visual Language
+- 10px border-radius, `rounded-2xl` for chat elements
+- Glassmorphism on AI inputs (`backdrop-blur-xl`, transparency)
+- Spring animations (stiffness 400, damping 30), scale-and-fade transitions
+- No gamification (badges, streaks, confetti). Mature and professional
+
+### Design Principles
+1. **Clarity over cleverness** — Clear hierarchy, generous whitespace, comfortable density
+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
+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

+# AI Refactor Plan — Adiuva Electron App
+
+> **Objective:** Transform the Electron app from a single-process AI integration into a local-first multi-agent client with plugin-based batch agents, multi-provider LLM support, E2E encrypted backup, granular permissions, and cloud backend integration.
+>
+> **Backend:** Lives in a separate repository. See `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`)
+  - `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)
+- [ ] Update `tsconfig.json` paths if needed to include `src/shared/`
+- **Files:** `src/shared/api-types.ts`, `tsconfig.json`
+- **Outcome:** Type-safe contracts for all backend communication. 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
+
+### Step 6.1 — Update Settings page for multi-provider config
+- [ ] Add provider management UI to Settings:
+  - List of configured providers with status (active/inactive/error)
+  - Add provider form: name dropdown (OpenAI, Anthropic, Google, Mistral, Groq, Ollama), API key input, model selection, endpoint (for Ollama)
+  - Set primary and fallback providers
+  - Test connection button per provider
+- [ ] Add auth section to Settings:
+  - Login/register form
+  - Current tier display with upgrade CTA
+  - Logout button
+- [ ] Add backup section to Settings:
+  - Create/view recovery passphrase
+  - Manual backup trigger
+  - Backup history with restore points
+  - Auto-backup schedule toggle
+- **Files:** `src/renderer/components/settings/` (new), route file
+- **Outcome:** Users can manage AI providers, auth, and backups from Settings.
+
+### Step 6.2 — Add Permission Dialog and Activity Log
+- [ ] Create `src/renderer/components/permissions/PermissionDialog.tsx`:
+  - Modal shown when a plugin requests new permissions
+  - Lists requested permissions with reasons
+  - Per-permission approve/deny toggles
+  - Shows plugin manifest info (name, description, version)
+- [ ] Create `src/renderer/components/permissions/ActivityLog.tsx`:
+  - Filterable table of all plugin activity
+  - Columns: timestamp, plugin name, action type, resource, status
+  - Filter by plugin, date range, action type
+  - Export as CSV
+- [ ] Add tRPC procedures for permission management and activity log queries
+- **Files:** `src/renderer/components/permissions/PermissionDialog.tsx`, `src/renderer/components/permissions/ActivityLog.tsx`, `src/main/router/index.ts`
+- **Outcome:** Transparent permission system with full activity audit trail.
+
+### Step 6.3 — Update AIChatPanel for backend-powered chat
+- [ ] Update `src/renderer/hooks/useAIChat.ts`:
+  - Support WebSocket streaming from backend (when online)
+  - Fall back to IPC streaming (when offline, using local orchestrator)
+  - Add connection status indicator (online/offline/reconnecting)
+  - Support execution plan responses: show plan preview, allow user to approve/modify before execution
+- [ ] Update `src/renderer/components/ai/AIChatPanel.tsx`:
+  - Add connection status badge
+  - Add tier indicator (shows current plan limitations)
+  - Plan approval UI: expandable plan steps with approve/reject buttons
+  - Enhanced error states: differentiate between offline, auth expired, rate limited, server error
+- [ ] Update `src/renderer/components/ai/FloatingChat.tsx`:
+  - Same streaming changes as AIChatPanel
+  - Compact plan approval for inline context
+- **Files:** `src/renderer/hooks/useAIChat.ts`, `src/renderer/components/ai/AIChatPanel.tsx`, `src/renderer/components/ai/FloatingChat.tsx`
+- **Outcome:** Chat UI seamlessly handles both online (backend) and offline (local) modes.
+
+---
+
+## 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 (EmailScanner plugin) |
+| `onnxruntime-node` | Local embeddings (optional) |
+
+---
+
+## 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).

+> The backend owns: orchestration logic, chat agent intelligence, prompt IP, auth, billing, and backup blob storage.
+> The backend NEVER persists user data. It receives context in requests, uses it for orchestration, and discards it.

+
+---
+
+## Step-by-Step Implementation
+
+### Step 1 — Project scaffolding
+- [ ] Initialize repo with the directory structure above
+- [ ] Write `requirements.txt`:
+  ```
+  fastapi>=0.115.0
+  uvicorn[standard]>=0.34.0
+  langchain>=0.3.0
+  langchain-openai>=0.3.0
+  pydantic>=2.10.0
+  python-jose[cryptography]>=3.3.0
+  stripe>=11.0.0
+  boto3>=1.35.0
+  slowapi>=0.1.9
+  sqlalchemy>=2.0.0
+  asyncpg>=0.30.0
+  alembic>=1.14.0
+  bcrypt>=4.2.0
+  python-dotenv>=1.0.0
+  httpx>=0.28.0
+  websockets>=14.0
+  pytest>=8.0.0
+  pytest-asyncio>=0.24.0
+  ```
+- [ ] Write `app/main.py`: FastAPI app with CORS (allow `app://`, `http://localhost:*`), lifespan (init DB pool, init agent registry), include all routers under `/api/v1`
+- [ ] Write `app/config/settings.py`: `Settings(BaseSettings)` with fields: `DATABASE_URL`, `JWT_SECRET`, `JWT_ALGORITHM` (default HS256), `STRIPE_SECRET_KEY`, `STRIPE_WEBHOOK_SECRET`, `S3_BUCKET`, `S3_REGION`, `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `OPENAI_API_KEY`, `CORS_ORIGINS`, `ENV` (dev/prod)
+- [ ] Write `Dockerfile`: Python 3.12 slim, multi-stage (builder + runtime), non-root user
+- [ ] Write `docker-compose.yml`: app, postgres:16, optional redis
+- [ ] Write `.env.example`
+- **Outcome:** Runnable FastAPI skeleton (returns 404 on all routes).
+
+### Step 2 — Pydantic schemas (API contracts)
+- [ ] Create `app/schemas.py` (mirrors `src/shared/api-types.ts` from Electron repo):
+  - `ChatRequest`: `message: str`, `context: ChatContext`, `execution_mode: Literal['direct', 'plan']`
+  - `ChatContext`: `user_profile: dict`, `relevant_documents: list[str]`, `recent_tasks: list[dict]`, `conversation_history: list[dict]`
+  - `ChatResponse`: `response: str`, `actions: list[PlanAction]`
+  - `PlanAction`: `type: Literal['create_record', 'update_record', 'delete_record', 'index_document', 'send_notification']`, `table: str | None`, `data: dict | None`
+  - `ExecutionPlan`: `agent: str`, `steps: list[PlanStep]`
+  - `PlanStep`: `action: str`, `prompt_template: str | None`, `variables: dict | None`, `data_from_step: int | None`
+  - `BackupMetadata`: `version: int`, `timestamp: int`, `checksum: str`, `chunk_count: int`
+  - `BillingTier`: `Literal['free', 'pro', 'power', 'team']`
+  - `AuthTokens`: `access_token: str`, `refresh_token: str`, `expires_at: int`
+  - `UserProfile`: `id: str`, `email: str`, `tier: BillingTier`
+- **Outcome:** All request/response models defined and validated.
+
+### Step 3 — Agent Registry + base classes
+- [ ] `app/core/agent_registry.py`:
+  - `BaseAgent(ABC)`:
+    - `user_id: str`, `shared_memory: dict`, `vector_store_context: list[str]`, `skills: list[str]`
+    - Abstract `get_name() -> str`, `get_description() -> str`
+  - `ChatAgent(BaseAgent)`:
+    - Abstract `async handle(query: str, context: dict) -> str`
+    - Abstract `get_tools() -> list` (LangChain tool definitions)
+    - Concrete `_tool_loop(llm, messages, tools, max_iter=5) -> str` — shared tool-calling loop
+  - `AgentRegistry` (singleton):
+    - `_agents: dict[str, ChatAgent]`
+    - `register(agent_class)` — decorator pattern
+    - `get(name) -> ChatAgent`
+    - `list_agents() -> list[dict]` — returns `[{name, description}]` for orchestrator prompt
+    - `async call_agent(name, query, context) -> str` — for inter-agent calls
+- [ ] Unit tests: register, get, list, call_agent with mock
+- **Outcome:** Pluggable agent framework.
+
+### Step 4 — Orchestrator
+- [ ] `app/core/orchestrator.py`:
+  - `async classify_intent(message, context, registry) -> str`:
+    - System prompt: "You are an intent classifier. Given the user message and context, decide which agent to route to. Available agents: {registry.list_agents()}. Respond with just the agent name."
+    - Uses gpt-4o-mini via LangChain for low latency
+    - Falls back to `task_agent` if no clear match
+  - `async route_single(agent_name, message, context) -> ChatResponse`:
+    - Instantiates agent from registry
+    - Calls `agent.handle(message, context)`
+    - Returns response + any actions the agent produced
+  - `async route_pipeline(agent_names, message, context) -> ChatResponse`:
+    - Executes agents in sequence
+    - Each agent receives `{...context, previous_results: [...]}`
+    - Final synthesis via LLM: "Summarize these agent results into a coherent response"
+  - `async orchestrate(request: ChatRequest) -> ChatResponse | ExecutionPlan`:
+    - Main entry point
+    - Classifies intent
+    - If `execution_mode == 'direct'`: route + return response
+    - If `execution_mode == 'plan'`: route + return execution plan with template IDs
+  - `async orchestrate_stream(request: ChatRequest) -> AsyncGenerator[str, None]`:
+    - Same as orchestrate but yields tokens for WebSocket streaming
+- [ ] Integration tests with mocked LLM and mocked agents
+- **Outcome:** Intelligent routing with single-agent and pipeline modes.
+
+### Step 5 — Execution Plan generator
+- [ ] `app/core/execution_plan.py`:
+  - `PromptTemplateRegistry`: dict of `template_id -> prompt_text`. Templates are server-side only — client receives IDs.
+  - `ExecutionPlanBuilder`:
+    - `add_step(action, params) -> self`
+    - `add_llm_step(template_id, variables) -> self`
+    - `add_data_step(action, data_from_step) -> self`
+    - `build() -> ExecutionPlan` — validates step references
+  - `PlanCache`:
+    - In-memory LRU (maxsize=1000)
+    - `cache_plan(key, plan)`, `get_plan(key)`, `get_all_playbooks() -> list[ExecutionPlan]`
+    - Playbooks are pre-built plans for common operations (e.g., "create task from email", "generate weekly report")
+- **Outcome:** Plans are cacheable as playbooks. Prompt IP never leaves the server.
+
+### Step 6 — Chat Agents
+- [ ] `app/agents/task_agent.py` — `@registry.register`:
+  - Description: "Manages tasks: create, update, list, suggest"
+  - Tools: `create_task(title, description, priority, due_date)`, `update_task(id, updates)`, `list_tasks(filters)`, `suggest_tasks(notes_context)`
+  - System prompt: PM-oriented, validates task structure, infers priority from context
+  - `handle()`: LLM + tool loop via `_tool_loop()`, returns response text + list of actions performed
+- [ ] `app/agents/calendar_agent.py` — `@registry.register`:
+  - Description: "Calendar management: events, conflicts, scheduling"
+  - Tools: `list_events(date_range)`, `detect_conflicts(events)`, `suggest_reschedule(conflict)`
+  - Works with event metadata passed in context (never raw calendar data stored)
+- [ ] `app/agents/email_agent.py` — `@registry.register`:
+  - Description: "Email analysis: classify, extract actions, draft responses"
+  - Tools: `classify_email(metadata)`, `extract_action_items(metadata)`, `draft_response(thread_context)`
+  - Only processes metadata sent by client — never raw email bodies
+- [ ] `app/agents/analytics_agent.py` — `@registry.register`:
+  - Description: "Workspace analytics: metrics, reports, trends"
+  - Tools: `calculate_metrics(task_data)`, `generate_report(period, data)`, `trend_analysis(data_points)`
+  - Crunches numbers from context, returns structured insights
+- [ ] `app/agents/__init__.py`: imports all agent modules to trigger `@registry.register` decorators
+- [ ] Unit tests per agent with mocked LLM
+- **Outcome:** Four specialized agents, all registered and tested.
+
+### Step 7 — API Routes
+
+#### 7a — Chat endpoint
+- [ ] `app/api/routes/chat.py`:
+  - `POST /api/v1/chat`:
+    - Request: `ChatRequest`
+    - Calls `orchestrate(request)` or `orchestrate()` + `build_plan()`
+    - Response: `ChatResponse` or `ExecutionPlan`
+  - `WebSocket /api/v1/chat/stream`:
+    - Client sends `ChatRequest` as first JSON frame
+    - Server yields token strings via `orchestrate_stream()`
+    - Final frame: JSON `ChatResponse` with `{"done": true, "response": "...", "actions": [...]}`
+    - Heartbeat ping every 30s to keep connection alive
+
+#### 7b — Plans endpoint
+- [ ] `app/api/routes/plans.py`:
+  - `GET /api/v1/plans/playbook`: Returns all playbooks available for the user's tier
+  - `GET /api/v1/plans/playbook/{plan_id}`: Returns a specific plan
+
+#### 7c — Backup endpoint
+- [ ] `app/api/routes/backup.py`:
+  - `PUT /api/v1/backup`: Accepts binary blob + metadata headers (`X-Backup-Version`, `X-Backup-Timestamp`, `X-Backup-Checksum`). Stores in S3 keyed by `{user_id}/{timestamp}`. Enforces tier limits:
+    - Free: 0 (no backup)
+    - Pro: 5 GB
+    - Power: 50 GB
+    - Team: unlimited
+  - `GET /api/v1/backup`: Returns latest blob for authenticated user. Supports `If-Modified-Since`.
+  - `GET /api/v1/backup/history`: Returns list of `BackupMetadata` (no blobs).
+  - `DELETE /api/v1/backup/{backup_id}`: Delete specific backup.
+
+#### 7d — Auth endpoint
+- [ ] `app/api/routes/auth.py`:
+  - `POST /api/v1/auth/register`: `{email, password}` → bcrypt hash → insert user → return `AuthTokens`
+  - `POST /api/v1/auth/login`: Validate credentials → return `AuthTokens`
+  - `POST /api/v1/auth/refresh`: Rotate refresh token → return new `AuthTokens`
+  - `GET /api/v1/auth/me`: Return `UserProfile` for current JWT
+
+#### 7e — Billing endpoint
+- [ ] `app/api/routes/billing.py`:
+  - `POST /api/v1/billing/checkout`: Creates Stripe checkout session → returns URL
+  - `POST /api/v1/billing/webhook`: Handles Stripe webhooks (subscription lifecycle)
+  - `GET /api/v1/billing/subscription`: Returns current subscription info
+  - `DELETE /api/v1/billing/subscription`: Cancels subscription
+
+- **Outcome:** Complete REST + WebSocket API.
+
+### Step 8 — Middleware
+
+#### 8a — Auth middleware
+- [ ] `app/api/middleware/auth.py`:
+  - FastAPI dependency: `get_current_user(token: str = Depends(oauth2_scheme)) -> UserProfile`
+  - Validates JWT signature, expiry, extracts `user_id` and `tier`
+  - Raises `401` on invalid/expired token
+  - Exempt routes: `/api/v1/auth/register`, `/api/v1/auth/login`, `/api/v1/billing/webhook`
+
+#### 8b — Rate limiter
+- [ ] `app/api/middleware/rate_limit.py`:
+  - Uses `slowapi` with `Limiter(key_func=get_user_id_from_jwt)`
+  - Tier-based limits:
+    - Free: 20 req/min
+    - Pro: 60 req/min
+    - Power: 120 req/min
+    - Team: 200 req/seat/min
+  - Custom 429 response with `Retry-After` header
+
+#### 8c — Sanitizer
+- [ ] `app/api/middleware/sanitizer.py`:
+  - Response middleware that scans response bodies
+  - Strips: system prompt fragments, agent internal reasoning, tool schemas, routing metadata
+  - Pattern-based detection + exact match against known prompt fingerprints
+  - Logs sanitization events for monitoring
+
+- **Outcome:** Secure, rate-limited API with prompt IP protection.
+
+### Step 9 — Billing & Tier management
+- [ ] `app/billing/stripe_service.py`:
+  - `create_checkout_session(user_id, tier) -> str`
+  - `handle_webhook(payload, sig_header) -> None`: processes `checkout.session.completed`, `customer.subscription.updated`, `customer.subscription.deleted`, `invoice.payment_failed`
+  - `get_subscription(user_id) -> dict | None`
+  - `cancel_subscription(user_id) -> None`
+- [ ] `app/billing/tier_manager.py`:
+  - `TierManager`:
+    - Feature matrix:
+      ```python
+      FEATURES = {
+          'free':  {'agents': 3, 'batch': False, 'providers': 1, 'backup_gb': 0},
+          'pro':   {'agents': -1, 'batch': True, 'providers': -1, 'backup_gb': 5},
+          'power': {'agents': -1, 'batch': True, 'providers': -1, 'backup_gb': 50, 'byok': True},
+          'team':  {'agents': -1, 'batch': True, 'providers': -1, 'backup_gb': -1, 'sso': True},
+      }
+      ```
+    - `get_tier(user_id) -> BillingTier`
+    - `check_feature(user_id, feature) -> bool`
+    - `get_rate_limit(tier) -> int`
+- **Outcome:** Stripe integration with tier-based feature gating.
+
+### Step 10 — Database (auth/billing only)
+- [ ] PostgreSQL schema via Alembic:
+  - `users`: `id UUID PK`, `email UNIQUE`, `password_hash`, `tier` (default 'free'), `stripe_customer_id`, `created_at`, `updated_at`
+  - `refresh_tokens`: `id UUID PK`, `user_id FK`, `token_hash`, `expires_at`, `created_at`
+  - `subscriptions`: `id UUID PK`, `user_id FK`, `stripe_subscription_id`, `tier`, `status`, `current_period_end`, `created_at`
+  - `backup_metadata`: `id UUID PK`, `user_id FK`, `s3_key`, `version`, `timestamp`, `checksum`, `size_bytes`, `created_at`
+- [ ] Initial Alembic migration
+- [ ] SQLAlchemy models in `app/models.py`
+- **Outcome:** Auth and billing persistence. Zero user data stored.
+
+### Step 11 — Testing & deployment
+- [ ] `tests/conftest.py`: TestClient fixture, mock LLM fixture (`AsyncMock` returning canned responses), mock agent fixture, test DB (SQLite in-memory for speed)
+- [ ] `tests/test_orchestrator.py`: classify_intent routing, single agent, pipeline, plan mode
+- [ ] `tests/test_agents.py`: each agent with mocked tools
+- [ ] `tests/test_auth.py`: register → login → access protected → refresh → expired token
+- [ ] `tests/test_backup.py`: upload → download → history → delete, tier limit enforcement
+- [ ] `Dockerfile` optimized for production (gunicorn + uvicorn workers)
+- [ ] GitHub Actions CI: lint (ruff), test (pytest), build Docker image
+- **Outcome:** Fully tested, deployable backend.

+1. **NEVER persist user data.** The DB stores only auth, billing, and backup metadata. User context arrives in requests and is discarded after processing.
+2. **NEVER expose prompts.** System prompts are composed server-side from fragments. Responses are sanitized before sending.
+3. **Stateless request handling.** No server-side session state. All context comes from the client + JWT.
+4. **Type hints everywhere.** All functions have full type annotations.
+5. **Test every agent.** Each chat agent has unit tests with mocked LLM responses.
+6. **Structured logging.** JSON logs with request ID correlation.
