-# 从 nanobot 到 OpenCane 的文档迁移说明
-
-## 本次调整内容
-
-1. 根目录原有 nanobot 文档全部归档到 `local-docs/nanobot-legacy/`
-2. 重建 OpenCane 文档体系，统一入口为根目录 `README.md` 和 `docs/README.md`
-3. 文档结构从“历史演进 + 分散专题”调整为“产品化结构 + API/运维可执行手册”
-
-## 命名与兼容
-
-- 项目名称：OpenCane
-- 代码包名：`opencane`
-- CLI 命令：`opencane`（兼容 `nanobot` 别名）
-- 配置目录：默认 `~/.opencane`（兼容读取 `~/.nanobot`）
-
-## 迁移完成状态（2026-02-21）
-
-已完成：
-
-- 源码包目录由 `nanobot/` 迁移到 `opencane/`
-- 构建与入口脚本迁移到 `opencane`（保留 CLI 别名 `nanobot`）
-- 文档、脚本、测试用例中的主命令统一为 `opencane`
-
-兼容保留：
-
-- `nanobot` CLI 别名
-- 读取历史数据目录 `~/.nanobot`
-- skill frontmatter 兼容 legacy `nanobot` metadata key
-
-不再兼容：
-
-- `python -m nanobot`
-- `from nanobot...` 导入路径
-
-这意味着：
-
-- 文档中的项目术语统一为 OpenCane
-- 建议执行命令使用 `opencane ...`
-
-## 迁移后的文档分层
-
-- 产品层：`docs/overview.md`
-- 上手层：`docs/quickstart.md`
-- 设计层：`docs/architecture.md`, `docs/data-flow.md`
-- 接口层：`docs/api/*.md`
-- 运行层：`docs/deployment-config.md`, `docs/operations-runbook.md`, `docs/security.md`
-- 规划层：`docs/roadmap.md`
-
-## 对历史文档的处理策略
-
-- 历史文档不删除，全部保留在归档目录
-- 新需求、缺陷修复、上线变更只更新新文档体系
-- 如发现历史文档与当前实现冲突，以新文档和源码为准
