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)

+# 05 — Code / Domain / Email / Knowledge
+
+## Git
+建立 provider adapter：
+- GitHub
+- GitLab
+- Gitea
+
+统一能力：
+- account connection
+- repositories
+- branches
+- commits
+- pull/merge requests
+- issues（基础）
+- webhook
+
+V1 不需要实现 Git hosting，只需要聚合外部 provider。
+
+## Domain/DNS
+建立 provider interface：
+- listZones
+- listRecords
+- createRecord
+- updateRecord
+- deleteRecord
+- verify
+
+Cloudflare 是第一个正式 adapter，Manual 是 fallback。
+
+DNS 操作必须有 preview + audit。
+
+## SSL
+统一 Certificate 模型，provider/adaptor 可插拔。
+至少支持状态：pending/active/expired/error。
+
+## Email
+V1 不做完整 Gmail clone。先实现：
+- EmailAccount
+- provider connection
+- inbox message metadata
+- send email abstraction
+- search metadata
+- attachments metadata
+
+支持 SMTP/IMAP adapter；Provider OAuth 可后续加入。
+
+## Knowledge
+实现：
+- Note
+- Document
+- folder/tree
+- tags
+- markdown/rich editor
+- code block
+- backlinks/resource links
+
+TipTap 为默认编辑器。
+
+重点：Note/Document 可以关联 Project/Resource/Task，成为操作上下文的一部分。
