## 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).
### Process Boundaries
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) ──ipcLink──► Preload (contextBridge) ──IPC──► Main (tRPC router + SQLite)
Renderer (React 19) ──ipcLink──► Preload (contextBridge) ──IPC──► Main (tRPC router + SQLite)
```
1. **Main process** (`src/main/`) — Node.js, owns the database and all business logic
- `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`)
### Main Process (`src/main/`)
2. **Preload** (`src/preload/trpc.ts`) — Exposes `window.electronTRPC` with `sendMessage()` / `onMessage()`
Owns the database and all business logic.
3. **Renderer** (`src/renderer/`) — React 19, never accesses Node APIs directly
- `lib/ipcLink.ts` — Custom TRPCLink that routes calls through `window.electronTRPC`
- `lib/trpc.ts` — `createTRPCReact<AppRouter>()` typed client
- `index.tsx` — QueryClient + tRPC + Router providers
- All data access is through `trpc.*.*useQuery()` / `trpc.*.*.useMutation()`
| 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 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:
- `__root.tsx` — Root layout wrapping everything in `AppShell`
- `index.tsx`, `tasks.tsx`, `timeline.tsx`, `projects.tsx`
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 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).
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 new table or column: edit `schema.ts`, run `drizzle-kit generate`, then `drizzle-kit push` (dev) or commit the migration file.
To add a table/column: edit `schema.ts` → `drizzle-kit generate` → `drizzle-kit push` (dev) or commit the migration.
### Adding a New Feature (end-to-end pattern)
### Adding a Feature (end-to-end)
1. **Schema** — Add table/columns to `src/main/db/schema.ts`
2. **Router** — Add a tRPC sub-router in `src/main/router/index.ts`, merge it into `appRouter`
3. **Types** — `AppRouter` is exported from `src/main/router/index.ts` and imported in `src/renderer/lib/trpc.ts` — types flow automatically
4. **UI** — Create components under `src/renderer/components/<feature>/`, use `trpc.*.*useQuery()` for data
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()`

**Orchestrator** (`orchestrator.ts`): Classifies user intent → routes to one of three specialist agents:
- **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`
### Orchestrator (`orchestrator.ts`)
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).

- Note create/update fires `upsertNoteEmbedding()` (fire-and-forget, errors swallowed)
- `migrateNotesIfNeeded()` backfills existing notes on first startup
- `searchNotes(query, limit=5)` is called by the Knowledge agent tool

### 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
- `@/*` path alias resolves to `src/renderer/*` (TypeScript + Vite + shadcn/ui all share this alias)
- shadcn/ui style: **new-york**, base color: **neutral**
- 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`
- Notes use Milkdown (`@milkdown/crepe`) as the markdown editor (`src/renderer/components/notes/MilkdownEditor.tsx`)
- Routes: `index`, `tasks`, `timeline`, `projects`, `notes.$noteId` (note ID is a URL param)
Tasks and checkpoints have `isAiSuggested` + `isApproved` columns. AI suggestions appear pending user approval (dashed borders in UI).

## Design Context
### Users
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.
### Target User
Freelancers and solo professionals managing client work (projects, tasks, notes, timelines). Single workspace, no enterprise overhead. AI as force multiplier.
### Brand Personality
**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.
### Brand
**Calm, intelligent, warm.** Thoughtful companion, not flashy tool. Confident and understated, never loud or gamified.
### Aesthetic Direction
- **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`)
- **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`
- **Corners**: 10px base radius, consistently rounded. Chat elements use `rounded-2xl`
- **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
### 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** — 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** — 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.
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.
