 OpenNexus 是一款本地优先的 AI 笔记与知识中枢。它将 Markdown Vault、全文与向量检索、知识库问答、可审计 Agent、扩展系统和多设备同步整合在一个桌面应用中。笔记与索引由用户掌控；需要模型或同步服务时，再按需连接本地或远程服务。
 
-当前发布版本为 **0.3.0-alpha.1**，主要支持 Windows x64。Alpha 版本用于验证完整业务闭环和部署方案，升级前请备份 Vault。

 凭据不会写入前端 `localStorage`。首次试用建议复制一份现有笔记目录，再用副本验证索引和同步行为。
 
+### 工作区图片存储
+
+在源码或所见即所得编辑器中粘贴、拖入或选择 PNG、JPEG、GIF、WebP 图片后，OpenNexus 会按内容哈希保存到当前 Vault 的 `attachments/<哈希前两位>/<SHA-256>.<扩展名>`。Markdown 使用相对路径引用图片，因此笔记目录整体复制、导出或同步后仍可定位原图；单张图片上限为 5 MiB，相同内容只保存一份。
+
+图片二进制不写入 SQLite。数据库中的 `workspace_assets` 保存路径、SHA-256、媒体类型、大小和原始文件名，`workspace_asset_links` 保存图片与笔记的引用关系。另一台设备收到 Vault 文件后，会在首次显示图片时校验路径哈希并重建本机元数据。
