DevOS v1 + Phase 2: unified resource model, infra ops, website deployment, AI chat ops

- Monorepo: NestJS API (Fastify) + React web (antd/ProComponents) + shared packages
- PostgreSQL/Prisma (unified resources, relations graph, audit, events, jobs)
- Auth/RBAC/workspace isolation, credential vault (AES-256-GCM)
- Servers/SSH, Docker discovery & lifecycle, Job Center
- Websites & deployments (git provider credential clone, env, health verification)
- Domains/DNS (Cloudflare adapter), certificates (TLS probe), monitoring
- Automation (cron/event/webhook HMAC + notifications), AI Gateway, MCP (29 tools)
- AI chat window (LLM function-calling + rules fallback, SSE streaming, approvals)
- Notes: Vditor WYSIWYG markdown editor, non-blocking autosave
- Tests: 35 unit/security tests; UI audit clean (desktop+mobile, deep links)

+# DevOS v1 Technology Stack
+
+## Frontend
+- React
+- TypeScript
+- Ant Design
+- Ant Design ProComponents
+- React Router
+- TanStack Query
+- Zustand
+- TipTap
+
+## Backend
+- Node.js
+- TypeScript
+- NestJS
+- Prefer Fastify adapter where appropriate
+
+## Data
+- PostgreSQL
+- Prisma
+- Redis
+
+## Infrastructure
+- Docker
+- SSH
+- Docker API
+- Nginx or Caddy integration
+- Linux
+- External DNS / cloud / Git / email APIs
+
+## Architecture Decision
+Prefer NestJS + Prisma for the initial implementation because the source discussion prioritizes modular structure and AI-friendly code comprehension.
+
+## Dependency Rule
+Do not introduce a new dependency without documenting:
+1. Why existing dependencies cannot satisfy the requirement
+2. Security and maintenance implications
+3. Operational impact
+4. Alternative considered
