feat(#1): Set up monorepo scaffold with pnpm workspaces + TurboRepo

Implements the foundational project structure including:
- pnpm workspaces configuration
- TurboRepo for build orchestration
- NestJS 11.1.12 API (apps/api)
- Next.js 16.1.6 web app (apps/web)
- Shared packages (config, shared, ui)
- TypeScript strict mode configuration
- ESLint + Prettier setup
- Vitest for unit testing (19 passing tests)

Fixes #1

**Multi-tenant personal assistant platform with PostgreSQL backend, Authentik SSO, and MoltBot
integration.**
## Project Overview
Mosaic Stack is a standalone platform that provides:
- Multi-user workspaces with team sharing
- Task, event, and project management
- Gantt charts and Kanban boards
- MoltBot integration via plugins (stock MoltBot + mosaic-plugin-*)
- PDA-friendly design throughout
**Repository:** git.mosaicstack.dev/mosaic/stack
**Versioning:** Start at 0.0.1, MVP = 0.1.0
## Technology Stack
| Layer | Technology |
|-------|------------|
| Frontend | Next.js 16 + React + TailwindCSS + Shadcn/ui |
| Backend | NestJS + Prisma ORM |
| Database | PostgreSQL 17 + pgvector |
| Cache | Valkey (Redis-compatible) |
| Auth | Authentik (OIDC) |
| AI | Ollama (configurable: local or remote) |
| Messaging | MoltBot (stock + Mosaic plugins) |
| Real-time | WebSockets (Socket.io) |
| Monorepo | pnpm workspaces + TurboRepo |
| Testing | Vitest + Playwright |
| Deployment | Docker + docker-compose |

## Development Workflow
### Branch Strategy
- `main` — stable releases only
- `develop` — active development (default working branch)
- `feature/*` — feature branches from develop
- `fix/*` — bug fix branches
### Starting Work
```bash
git checkout develop
git pull --rebase
pnpm install
Running Locally
# Start all services (Docker)
docker compose up -d
# Or run individually for development
pnpm dev # All apps
pnpm dev:api # API only
pnpm dev:web # Web only
Testing
pnpm test # Run all tests
pnpm test:api # API tests only
pnpm test:web # Web tests only
pnpm test:e2e # Playwright E2E
Building
pnpm build # Build all
pnpm build:api # Build API
pnpm build:web # Build Web
Design Principles (NON-NEGOTIABLE)
PDA-Friendly Language
NEVER use demanding language. This is critical.

Visual Indicators
Use status indicators consistently:
- 🟢 On track / Active
- 🔵 Upcoming / Scheduled
- ⏸️ Paused / On hold
- 💤 Dormant / Inactive
- ⚪ Not started
Display Principles
1. 10-second scannability — Key info visible immediately
2. Visual chunking — Clear sections with headers
3. Single-line items — Compact, scannable lists
4. Date grouping — Today, Tomorrow, This Week headers
5. Progressive disclosure — Details on click, not upfront
6. Calm colors — No aggressive reds for status
Reference
See docs/DESIGN-PRINCIPLES.md for complete guidelines.
For original patterns, see: jarvis-brain/docs/DESIGN-PRINCIPLES.md
API Conventions
Endpoints
GET /api/{resource} # List (with pagination, filters)
GET /api/{resource}/:id # Get single
POST /api/{resource} # Create
PATCH /api/{resource}/:id # Update
DELETE /api/{resource}/:id # Delete
Response Format
// Success
{
data: T | T[],
meta?: { total, page, limit }
}
// Error
{
error: {
code: string,
message: string,
details?: any
}
}
Brain Query API
POST /api/brain/query
{
query: "what's on my calendar",
context?: { view: "dashboard", workspace_id: "..." }
}
Database Conventions
Multi-Tenant (RLS)
All workspace-scoped tables use Row-Level Security:
- Always include workspace_id in queries
- RLS policies enforce isolation
- Set session context for current user
Prisma Commands
pnpm prisma:generate # Generate client
pnpm prisma:migrate # Run migrations
pnpm prisma:studio # Open Prisma Studio
pnpm prisma:seed # Seed development data
MoltBot Plugin Development
Plugins live in plugins/mosaic-plugin-*/ and follow MoltBot skill format:
# plugins/mosaic-plugin-brain/SKILL.md
---
name: mosaic-plugin-brain
description: Query Mosaic Stack for tasks, events, projects
version: 0.0.1
triggers:
- "what's on my calendar"
- "show my tasks"
- "morning briefing"
tools:
- mosaic_api
---
# Plugin instructions here...
Key principle: MoltBot remains stock. All customization via plugins only.
