 ## [Unreleased]
 
+## [1.0.58-beta.4] - 2026-08-12
+
+### Added
+
+- **Multi-skill installation and upgrade** — fresh installs, `dws skill setup`,
+  and `dws upgrade` now use the multi-skill layout by default. Existing mono
+  installations migrate during upgrade; mono remains an explicit legacy option.
+- **Native streaming-card mentions** — `dws chat message send-card` now accepts
+  `--at-open-dingtalk-ids` and `--at-all` for group cards and forwards them to
+  `create_and_send_card`, matching the existing shortcut behavior without
+  changing single-chat card creation.
+- **Expanded Minutes workflows** — 27 public Minutes shortcuts now cover
+  upload, download, export, recording, analysis, sharing, and recovery flows;
+  every write command keeps an explicit confirmation requirement.
+- **Chat command discovery** — 30 existing typed Chat commands are now
+  available in the runtime Schema and Agent catalog, with sensitive writes
+  carrying their required confirmation metadata.
+
+### Changed
+
+- **Chat read results** — typed commands and shortcuts now expose a consistent
+  top-level `messages` list with stable `messageId` and `text` fields while
+  retaining existing response envelopes and fields.
+- **Wiki feed results** — Wiki feed list output now formats time fields and
+  trims excess fields. Its `--limit` default is 10 and maximum is 20.
+- **Developer command results** — the `dev` and selected `devapp` commands now
+  use the unified result envelope for consistent success, pending, partial,
+  and failure reporting.
+- **Evaluation dispatch hardening** — `/eval` now uses a verifiable polling
+  relay instead of direct access from the hosted runner, binding the workflow,
+  comment, PR head, parameters, and result provenance.
+
+### Fixed
+
+- **Streaming-card update acknowledgement** — accepts the pre-production
+  `success: true` response from `update_streaming_card` as affirmative write
+  evidence while preserving explicit negative, conflicting, and bizId-drift
+  failures, so Agents do not repeat an update that the service already applied.
+- **Text input bounds** — literal input, stdin, and `@file` inputs now all
+  enforce the same byte limit; file reads validate the opened descriptor and
+  cannot exceed the limit after a path replacement or file growth.
+- **Evaluation PR comments** — restores `/eval` PR conversation comments with
+  the least required pull-request write permission and actionable GitHub 403
+  diagnostics.

+> The setup command can remove the opposite-mode layout (`dws/` for multi, DWS-managed multi Skills for mono) and stale managed Skills not in the bundle. DWS records ownership, installer version, source, and content digest centrally in `~/.dws/skills-state.json` (or `$DWS_CONFIG_DIR/skills-state.json`). Exact official names shipped before the centralized state remain a frozen migration list. A `dingtalk-*` prefix alone never authorizes cleanup, so other same-prefix market/user Skills are preserved. Every removal is previewed before confirmation and preserved under `~/.dws/skill-backups/<timestamp>/`; a directory that cannot be backed up is never removed. In a non-interactive shell, first run `--dry-run` and inspect its output; only then may the caller explicitly choose the scripting-only confirmation bypass.

+After a multi setup or upgrade, DWS stores the official bundle snapshot and centralized ownership metadata in `~/.dws/skills-state.json` (or `$DWS_CONFIG_DIR/skills-state.json`). Every upgrade installs and overwrites the complete bundled Skill set from that release. Deleting or excluding a bundled Skill is not sticky: the next upgrade restores it. `dws upgrade --force` additionally allows reinstalling the current CLI version when no newer version is available.

+# Drive Shortcut 对齐与超越 Lark CLI
+
+## 目标与判定口径
+
+本轮以 Lark CLI `drive` 的 38 个 shortcut 为对照，但不把“同名命令数量”当完成标准。对齐按用户任务判定：
+
+1. `drive +...` 有更稳定的 Agent 主入口时，提供 Shortcut，并发布 Selection、Safety、Result 与 Pagination。
+2. 钉钉已经在其他产品提供更成熟入口时，Skill 明确跨产品路由，不在 Drive 重复实现。
+3. 只有原子能力且 Shortcut 不增加校验、编排或投影价值时，保留 Runtime Schema leaf，不制造同义别名。
+4. 下层接口不存在或无法满足相同语义时，明确记录 gap；不得用空数组、空对象或只返回任务提交结果伪装完成。
+
+成功判定统一为：进程成功 + 统一结果 `ok=true/outcome=success` + 必要业务字段 + 真实数据读回或本地字节校验。服务端显式返回空数组可以是合法业务空结果；空响应、缺少数组、数组类型错误、坏元素、`success=false`、写入缺少终态证据都必须失败。
+
+## Lark 38 项映射
+
+| Lark Drive shortcut | DWS 路由 | 结论与原因 |
+|---|---|---|
+| `+upload` | `drive +upload` | 对齐并增强：工作目录边界、OSS PUT、严格 commit、元数据读回。 |
+| `+create-folder` | `drive +create-folder` | 对齐并增强：要求新 fileId 和名称读回。 |
+| `+create-shortcut` | `drive +create-shortcut` | 对齐并增强：明确 shortcut≠copy，创建后读回。 |
+| `+download` | `drive +download` | 对齐并增强：真实落盘、no-clobber、原子发布、非零字节。 |
+| `+preview` | `drive +cover`（有限） | 不完全对齐：钉钉当前只提供封面/缩略图读取，没有等价的服务端多格式预览转换接口。 |
+| `+cover` | `drive +cover` | 对齐：严格读取封面/缩略图对象。 |
+| `+add-comment` | `doc +comment-create` | 用户任务对齐；评论归在线文档协作域，Drive 不复制一套。 |
+| `+list-comments` | `doc +comment-list` | 用户任务对齐；Doc 已有类型、状态与分页。 |
+| `+batch-query-comments` | `doc +review` / `doc +comment-list` | 超越：可聚合未解决评论与确定性正文上下文；跨文档批量仍由调用方按节点编排。 |
+| `+resolve-comment` | `doc +comment-update`（有限） | 部分对齐：DWS 可更新评论，但当前下层未声明独立 resolve 状态接口。 |
+| `+restore-comment` | 无等价 | gap：钉钉当前下层未暴露恢复已删除评论的等价能力。 |
+| `+add-reply` | `doc +comment-reply` | 对齐。 |
+| `+list-replies` | `doc +comment-list` | 用户任务对齐：评论列表返回回复上下文；无独立 Drive reply 目录。 |
+| `+update-reply` | `doc +comment-update` | 对齐到评论/回复统一更新语义。 |
+| `+delete-reply` | `doc +comment-delete` | 对齐到评论/回复统一删除语义，高风险确认。 |
+| `+react-reply` | `doc +comment-reply`（有限） | 部分对齐：支持表情回复；不声称拥有 Lark 的独立 reaction identity。 |
+| `+export` | `doc +export` | 用户任务对齐并增强：提交、轮询、安全下载一体化。 |
+| `+export-download` | `doc +export` / `doc +export-get` | 超越：常规一体化，`+export-get` 仅作中断恢复。 |
+| `+import` | `doc +import` | 用户任务对齐并增强：转换白名单、上传 fallback、轮询终态。 |
+| `+version-history` | `drive +version-history` | 对齐并增强：严格空结果与分页。 |
+| `+version-get` | `drive +version-get` | 对齐并增强：精确版本号，零命中失败。 |
+| `+version-revert` | `drive +version-revert` | 对齐并增强：版本预检、高风险确认、节点读回。 |
+| `+version-delete` | 无等价 | gap：钉钉当前普通文件版本接口没有删除历史版本能力。 |
+| `+move` | `drive +move` | 对齐；与 copy/shortcut 明确消歧并发布确认。 |
+| `+delete` | `drive +delete` | 对齐；移入回收站、高风险确认、终态证据。 |
+| `+status` | `drive +inspect` | 超越：远端身份、统计、公开状态和封面按需聚合；不伪装成本地同步状态。 |
+| `+push` | `drive +upload`（单文件） | 部分对齐：单文件上传可靠；没有可靠的目录 diff、冲突和远端删除传播语义，因此不提供同名批量 push。 |
+| `+pull` | `drive +download`（单文件） | 部分对齐：单文件下载可靠；目录级增量拉取需稳定路径、hash 与冲突策略，当前接口不完整。 |
+| `+sync` | 无等价 | gap：在缺少稳定远端内容 hash、rename/delete journal 和冲突版本向量时，双向同步会有数据覆盖风险。 |
+| `+task_result` | `doc +export-get` / 导入任务恢复入口 | 用户任务对齐；DWS 按任务所属产品提供类型化恢复入口，不保留 Lark 的下划线泛化命令。 |
+| `+apply-permission` | `drive permission apply` raw leaf | 下层能力存在但未提升为 Shortcut：需要真实申请上下文和权限夹具，无法在通用 E2E 中安全创建。 |
+| `+member-add` | `doc +access-grant` | 用户任务对齐并增强：解析接收人、批量 ledger、首次写入前停止。 |
+| `+member-list` | `drive permission list` / `doc +inspect --include-permissions` | 对齐；常规 Agent 场景优先 Doc 聚合检查。 |
+| `+permission-get-setting` | `drive permission list` + `drive +publish-get` | 部分对齐：协作者与互联网公开是两个独立安全域，没有一个与 Lark setting 完全同构的钉钉接口。 |
+| `+secure-label-list` | 无等价 | gap：当前 DWS/钉钉下层没有可声明的 Drive 安全标签目录接口。 |
+| `+secure-label-update` | 无等价 | gap：没有安全标签写接口，不能用普通权限或公开状态替代。 |
+| `+search` | `drive +search` | 对齐并增强：过滤、严格数组和分页；在线文档搜索路由 `doc +search`。 |
+| `+inspect` | `drive +inspect` | 对齐并增强：必达元数据 + 可选聚合，部分失败不伪装成功。 |
+
+## DWS 超出 Lark Drive 的可挖掘能力
+
+- `+list`：严格目录分页，而不是把缺字段当空目录。
+- `+recent`：最近访问/编辑与创建人筛选。
+- `+stats`：阅读、编辑、评论、点赞、预览和下载统计。
+- `+recycle-list` / `+recycle-restore`：显式回收项身份与恢复后读回。
+- `+star-list` / `+star-add` / `+star-remove`：个人收藏完整闭环。
+- `+publish-get` / `+publish-unset`：互联网公开独立安全域与关闭后读回；`+publish-set` 保留为 unavailable 诊断入口。
+- `+version-download`：历史版本真实字节下载与本地 artifact 校验。
+- `+rename`：写后读回验证。
+
+普通钉盘文件的独立 `copy` 是额外确认出的部分 gap：钉钉当前 `doc/copy_document` 对该对象会生成 `.dlink`，不是字节独立副本。`drive +copy` 因此只接受在线对象；普通文件需要快捷入口时用 `+create-shortcut`，需要独立副本时用 `+download` 后 `+upload`。这不是完整的服务端原子 copy，对大文件也不能宣称完全等价。
+
+互联网公开开启也是账号/对象能力 gap：真实普通文件与在线文档夹具都由服务端返回 `operation.notSupported`。`+publish-get` 与关闭语义可验证，但 `+publish-set` 在找到 eligible 节点完成 set→get→unset 闭环前保持 `unavailable` 且不进入公开 Agent catalog。
+
+## 端到端门禁
+
+每个公开 Drive shortcut 必须至少覆盖：
+
+- Cobra 参数、静态确认、Shortcut Execute、MCP 调度和最终输出；
+- 明确业务空集合、空响应、缺字段、错误类型、坏元素、`success=false`；
+- 写入的 ID/终态证据与读回不一致；
+- 下载的本地路径边界、no-clobber、真实字节数；
+- 真实账号数据：读命令必须命中已知非空夹具或明确验证合法空集合；写命令必须创建隔离资源、读回、必要时下载比对字节并清理。
+
+发布前运行 `make build`、完整 Go 测试、Schema 生成/漂移/策略检查，并保存不含账号业务内容的结构化 E2E 汇总。

+- 新装与升级默认使用 multi 布局，mono 在兼容期内保留显式 opt-in。
+- 每次升级使用当前版本的官方清单全量覆盖预制 Skill。
+- 删除或替换任何目录前先创建可恢复备份，备份失败不修改该 Agent 目标。
+- 只清理能够证明由 DWS 管理的目录，不通过名称前缀推断所有权。
+- 所有安装入口对部分失败返回非零状态，不误报整体成功。
+- 安装预览、确认和实际执行使用同一份计划。
+
+### 2.2 非目标
+
+- 不建设独立的 `dws skill mode status|set|rollback` 产品面。
+- 不持久化用户对预制 Skill 的本地删除或排除意图。
+- 不提供跨所有 Agent 目标的事务式回滚。
+- 不把市场 Skill 纳入预制 Skill 的升级和清理范围。
+
+## 3. 业内调研
+
+对主流 CLI 与 Agent Skill 分发方式的公开实现进行归纳后，可以得到以下共性：
+
+| 观察 | 对 DWS 的启示 |
+|---|---|
+| 多个产品能力通常以同级 Skill 目录安装，由 Agent 按目录发现 | multi 使用平铺的产品 Skill，并保留一个共享 Skill 承载公共协议 |
+| CLI 本体安装和 Agent Skill 安装是两个生命周期 | DWS 可以在 CLI 安装、setup 和 upgrade 中触发 Skill 同步，但二者的失败与状态必须分别报告 |
+| 生态安装器通常天然采用 multi，不提供 mono/multi 状态机 | DWS 的模式切换保持为重新执行 setup，不新增长期驻留的 mode lifecycle |
+| 市场 Skill 与 CLI 预制 Skill 可能落在同一 Agent 根目录 | 必须使用统一所有权元数据识别受管目录，名称前缀不能作为删除依据 |
+| 多 Skill 更新常以新清单刷新官方集合 | DWS 使用当前 bundle 官方清单全量覆盖，新增 Skill 自动加入，本地删除不视为持久化排除 |
+| 制品可能需要同时服务无运行时依赖、离线和多镜像环境 | DWS 保留 embed、zip 和平台安装脚本，不把单一生态包管理器设为唯一入口 |
+| 中断的复制和原地覆盖容易破坏最后一个可用版本 | 缓存与 Go upgrade 的 Agent 目标采用 staging publish；发布失败自动恢复该目标的完整旧集合 |
+| Agent 通常以 `SKILL.md` 为入口，其他文件按引用或工具规则按需读取 | 安装元数据使用不被内容引用的隐藏文件，并保证其内容不包含 Agent 指令 |
+
+本节只保留可复用的工程结论，不记录具体产品、仓库、版本或逐项能力对照，也不构成
+DWS 对任何外部实现的持续兼容义务。后续设计以 DWS 自身约束和本 RFC 的行为合同为准。
+
+## 4. 布局合同
+
+| 模式 | Agent 目录布局 | 选择方式 |
+|---|---|---|
+| multi（默认） | `<agent-home>/dingtalk-*/` 与必选 `dingtalk-shared/` | 默认；`dws skill setup --mode multi` |
+| mono（兼容） | `<agent-home>/dws/` | `dws skill setup --mode mono` 或安装器的 mono opt-in |
+
+模式切换通过重新执行 setup 完成。安装 multi 前备份并移除 mono 的 `dws/`；安装
+mono 前只备份并移除能够证明由 DWS 管理的 multi 目录。两个方向都不提供隐式、
+不可恢复的删除。
+
+## 5. 官方集合与升级策略
+
+当前版本 bundle 中的 multi 目录清单是升级集合的唯一权威来源。普通 upgrade 和
+`--force` 都安装并覆盖该版本的全部官方预制 Skill：
+
+- 本地删除的预制 Skill 会在下一次升级恢复；
+- setup 时通过 `--exclude` 暂时排除的 Skill 会在下一次升级恢复；
+- 新版本新增的官方 Skill 会自动安装；
+- 用户对预制 Skill 的本地修改会被官方版本覆盖；
+- `dingtalk-shared` 始终随官方集合安装。
+
+`~/.dws/skills-state.json`（设置 `DWS_CONFIG_DIR` 时位于该目录）不参与安装集合
+求解，也不保存排除策略。它既记录结果快照，也集中记录 multi Skill 的所有权和
+provenance，供安全清理、诊断与后续迁移使用。
+
+## 6. 目录所有权
+
+每次 multi setup 或 upgrade 全部成功后，DWS 在统一的
+`~/.dws/skills-state.json` 中写入：
+
+```json
+{
+  "version": "v0.2.14",
+  "official_skills": ["dingtalk-aitable"],
+  "updated_skills": ["dingtalk-aitable"],
+  "managed_skills": [
+    {
+      "name": "dingtalk-aitable",
+      "version": "v0.2.14",
+      "source": "dws-upgrade",
+      "digest": "sha256:<64 个十六进制字符>",
+      "digest_scope": "skill-directory-v1"
+    }
+  ],
+  "updated_at": "2026-08-11T12:34:56Z"
+}
+```
+
+每条 `managed_skills` 记录代表一个由 DWS 管理的官方 Skill。`version` 记录安装该
+副本的 DWS/发布包版本，`source` 记录安装入口，`digest` 是对 bundle 中 Skill 目录
+全部普通文件按相对路径排序后计算的内容摘要。摘要用于诊断和来源追踪，不作为后续
+升级的完整性门禁；用户修改 Skill 内容后，DWS 仍保有明确管理权并能在下一次升级时
+覆盖恢复。
+
+清理 stale Skill 或切换到 mono 时，只接受以下所有权证据：
+
+1. Skill 名称存在于统一状态的 `managed_skills` 中；
+2. 统一状态上线前曾发布过的官方 Skill 精确名称集合。
+
+历史集合是冻结的迁移清单，包含 `dws-shared` 以及已退役、折叠或仍在发布的旧官方
+目录名。仅有 `dingtalk-*` 前缀不构成所有权证据。因此，市场或用户创建的
+`dingtalk-custom` 等非官方精确名称目录不会被迁走。
+
+### 6.1 对 Agent 的影响
+
+Skill 目录内不再放置 DWS 所有权文件，也不增加非通用 frontmatter 字段。支持的
+Agent 仍只需以 `SKILL.md` 发现和加载 Skill；统一元数据位于 Agent Skill 目录之外，
+不会成为提示词上下文或影响 Agent 行为。
+
+## 7. Setup：Plan → Confirm → Execute
+
+`dws skill setup` 分为三个阶段：
+
+1. **Plan**：只读计算目标、安装集合以及所有待备份路径；
+2. **Confirm**：`--dry-run` 和交互确认渲染同一份计划；
+3. **Execute**：确认后严格执行计划中的备份和安装。
+
+安全要求：
+
+- 非交互环境未传 `--yes` 时拒绝执行；
+- 用户拒绝确认时必须零文件写入；
+- 备份失败时跳过整个 Agent 目标，不开始铺设相反布局；
+- 同一目标先完成所有必要备份，再复制新集合；
+- multi Skill 必须在同级 staging 中完成复制，再原子发布到正式目录；
+- 任意 `skipped > 0` 都返回非零退出码，并且不写入完整成功快照；
+- 一个 Agent 目标失败不阻止其他目标尝试，但最终结果仍为失败。
+
+## 8. Upgrade 与恢复语义
+
+升级器对每个 Agent 目标执行：
+
+1. 只读计算对面布局、过期受管 Skill 和同名官方 Skill；
+2. 在目标文件系统的 staging 中复制完整新集合；
+3. staging 全部成功后，才将旧集合移入备份目录；
+4. 逐项发布 staging；任一发布失败时删除已发布的新目录，并逆序恢复该目标的全部旧目录；
+5. 仅在没有目标失败且至少一个目标成功时更新状态快照。
+
+Go upgrade 当前提供 **单 Agent 目标级事务恢复**：复制失败发生在旧目录移动前；
+备份中途失败会恢复此前已移动的目录；发布中途失败会恢复该目标的完整旧集合。不同
+Agent 目标仍彼此独立，一个目标失败不会回滚此前已经成功升级的其他目标，这与
+“不提供跨所有 Agent 目标的事务式回滚”非目标保持一致。
+
+## 9. 备份合同
+
+- 路径：`~/.dws/skill-backups/<UTC 时间戳>/...`；
+- 主要操作：同一文件系统内使用 rename 移动；
+- 失败语义：备份失败时原目录保持不变，目标安装失败；
+- 可见性：计划和执行日志显示原路径与备份路径；
+- 保留策略：自动修剪，仅保留最近 5 批。
+
+备份是安装安全机制，不等于独立 rollback 产品。需要切回 mono 时重新运行
+`dws skill setup --mode mono`。
+
+## 10. 缓存与制品
+
+发布制品和二进制内嵌内容同时携带 mono 与 multi 源树。`~/.dws/skills/` 只是
+setup 在未显式指定 `--source` 时的本地回退缓存。
+
+缓存刷新必须采用同级 staging + publish：
+
+1. 在 staging 中完整复制并验证新树；
+2. 发布前保留旧缓存；
+3. 通过 rename 发布新缓存；
+4. 复制或发布失败时保留或恢复旧缓存；
+5. 空、缺失或损坏的 bundle 不能擦除有效缓存。
+
+## 11. 安装入口一致性
+
+以下入口都遵守本 RFC：
+
+| 入口 | 默认模式 | 失败合同 |
+|---|---|---|
+| `dws skill setup` | multi | 部分失败返回非零；不写完整成功状态 |
+| `dws upgrade` | bundle 含 multi 时安装 multi | 目标失败返回失败；下次全量重试 |
+| `scripts/install.sh` | multi | 任一检测到的目标失败则脚本非零 |
+| `scripts/install.ps1` | multi | 任一检测到的目标失败则脚本非零 |
+| `scripts/install-skills.sh` | multi | 任一检测到的目标失败则脚本非零 |
+| npm `install.js` | multi | 任一检测到的目标失败则 postinstall 失败 |
+
+Homebrew 不直接向 Agent home 铺设 Skill；安装 CLI 后由 setup 执行相同流程。
+
+## 12. 验收与回归门禁
+
+合入和后续修改至少覆盖：
+
+- mono → multi、multi → mono 互斥切换；
+- 状态上线前的官方 multi 目录切换 mono 时能够被精确迁移；
+- 未登记的同前缀市场/用户 Skill 在刷新和切换后仍存在；
+- 统一状态中登记的过期官方 Skill 被备份并移除；
+- 备份、复制、统一状态写入、缓存 publish 故障注入；
+- 非交互确认拒绝与显式 `--yes`；
+- 部分失败返回非零且不写错误状态快照；
+- 复制失败不留下 Agent 可见的残缺官方目录；
+- 普通 upgrade 恢复被删除的预制 Skill，并安装新增官方 Skill；
+- Windows、macOS、Linux 的路径和覆盖率门禁；
+- npm、Shell、PowerShell 与包管理器安装冒烟。
+
+## 13. 后续演进
+
+- 收敛各安装入口中的 Agent home 清单，减少跨语言复制；
+- 如确有运维需求，可单独设计备份查看和显式恢复命令；
+- mono 的物理删除必须作为独立变更，在 multi 内容、安装入口和迁移回归稳定后推进；
+- `managed_skills` 字段若演进，必须同步更新所有安装入口和跨平台回归。

-## 0. TL;DR
-
-1. **本分支 = skill 内容框架 + 相对 mono 的内容质检**：固化 `skills/multi` 组织合同，并用 **mono 单 skill 布局作对照基准**做覆盖/结构/漂移门禁（文档 + CI 内容护栏）。
-2. **对齐悟空**：只取内容树组织概念；质检以 **DWS-native** 设计为主（已有 policy/测试可复用）。悟空 `validate-multiskill-bundle.py` 仅借鉴「frontmatter / 断链 / requires」类检查思路，**不**移植 bundle/安装校验。
-3. **安装/升级行为**与 `402429ac`/`d5c8982c` → **单独 follow-up 分支**，本方案只登记。
-4. 质检 **不改**默认安装哪棵树；只保证 multi 内容相对 mono **可解释、可覆盖、可回归**。
-
-### 0.1 IN SCOPE
-
-| 类别 | 包含 |
-|---|---|
-| 内容树结构 | `skills/mono/` 与 `skills/multi/<name>/` 目录合同 |
-| 单 skill 约定 | `SKILL.md` frontmatter / 契约块 / Golden Route；`references/`；可选 `scripts/` |
-| 共享内容 | `dingtalk-shared` 职责与被引用方式；与 mono 全局文映射（文档级） |
-| 命名与集合 | `dingtalk-*` + `dingtalk-shared`；相对悟空的共有/独有清单（文档） |
-| Zip **内容布局合同** | `mono/` / `multi/` / 根 mono 副本的内容含义与树形状；不改安装默认 |
-| **Mono↔multi 内容质检** | 覆盖、结构、漂移三类门禁；复用/扩展现有 policy 与测试；缺口修复属内容编辑（另批或同分支内容 Phase） |
-| 内容架构文档 | 本文件 + 可选短文（架构合同 + 质检矩阵） |
-
-### 0.2 OUT OF SCOPE
-
-| 类别 | 去向 |
-|---|---|
-| 安装默认 multi、upgrade always-multi | Follow-up 分支（`402429ac`/`d5c8982c`） |
-| `LocateSkillsRoot` / `skill_setup` / `paths.go` / `skillhome` / install 脚本行为 | 同上 |
-| 安装/运行时 manifest、state.json、mode 切换、telemetry header | 拒绝或行为分支 |
-| 悟空 `_install.sh` / dual / Qwen / RewindDesktop / pod | 拒绝 |
-| 非 skill 内容的 CLI 功能（schema/shortcut 代码等） | 拒绝 |
-| 把质检做成「改安装默认值」的后门 | 拒绝 |

-## 1. 内容现状盘点
-
-### 1.1 DWS `skills/mono`（质检对照基准 · 单 skill）
-
-```text
-skills/mono/
-├── SKILL.md
-├── references/
-│   ├── products/<area>.md|…/   # 产品能力面（质检「覆盖」主源）
-│   ├── error-codes.md、…  # 全局协议（无 recovery 闭环）
-│   └── best_practices/…
-└── scripts/
-```
-
-### 1.2 DWS `skills/multi`（内容主体）
-
-```text
-skills/multi/
-├── dingtalk-shared/     # 跨产品契约 / routing / 全局协议应落点
-└── dingtalk-*/     # 19 产品 + 各 references、scripts
-```
-
-仅 DWS 有（悟空无）：dev, event, hrbrain, markdown, pat, profile, skill。
-
-### 1.3 悟空 `dingtalk-skills/`（内容组织对照，非质检权威）
-
-Flat `dingtalk-*` + `dingtalk-shared`；单 skill 骨架同构。**不作为 mono 覆盖基准**（集合更小、不同源）。
-
-### 1.4 Zip 内容布局合同
-
-| Zip 路径 | 内容含义 |
-|---|---|
-| `<root>/` | mono 副本（兼容） |
-| `<root>/mono/` | 显式 mono 内容源 |
-| `<root>/multi/` | 与 `skills/multi/` 同构 |
-
-质检可断言「源树形状」；**不**断言安装面默认选哪棵。
-
-### 1.5 现有 DWS skill 内容质检资产（复用清单）
-
-| 资产 | 作用 | 与 mono↔multi 质检关系 |
-|---|---|---|
-| `scripts/policy/check-skill-commands.sh` + `skill-command-check/` | Skill 文内 `dws …` 命令路径存在性 | **复用**（命令真实性）；非覆盖映射 |
-| `scripts/policy/check-skill-context-budget.sh` | chat/event/mono/`dingtalk-shared` 上下文预算与冷启动约束 | **复用**（结构/预算）；可扩展 shared 引用规则 |
-| `scripts/policy/check-multi-im-skill-chain.sh` + `multi-im-skill-chain/` | IM 意图单默认路由、retired scripts、handoff | **复用**（chat/event 链）；面窄 |
-| `test/unit/skill_docs_policy_test.go` | 退役命令、event 扁平输出契约等 | **复用**；可加 mono↔multi 断言 |
-| `test/unit/whiteboard_skill_docs_test.go` | mono/multi whiteboard recipes **字节一致** | **样板**：产品面「同源文件」门禁范式 |
-| `test/skill_static`（`-tags skill_verify`） | 文内命令 vs Cobra；multi 查 flag | **复用**（opt-in 深度）；非 CI 默认全量时可保持 tags |
-| `test/skill_e2e` / `test/run_skill_tests.py` | 执行层 / 用例驱动 | **偏行为**；本分支质检默认不依赖 e2e |
-| `Makefile` → `policy` 含 context-budget、multi-im-skill-chain；`skill-command-integrity` 独立 | 已有 CI 钩子 | 新门禁优先挂同类 policy / `test/unit` |
-
-**缺口（尚无的门禁）**：系统的「mono `references/products/*` → multi 目录/文」覆盖表；frontmatter 全集完备性；orphan scripts。全局协议中 **确认门禁 / Schema 教学已补**；**recovery 闭环已从 skill 移除（不再作为缺口）**。
-
-### 1.6 悟空侧类比质检
-
-| 悟空 | 说明 | 本分支 |
-|---|---|---|
-| `scripts/validate-multiskill-bundle.py` | 校验 **已打好的 bundle zip**：frontmatter keys/category、`requires`、markdown 断链、scenario 编排 | **Adapt 思路** → DWS 源树（`skills/multi` + 对照 mono），不跑 zip 安装语义 |
-| `sync-monolith-to-multiskill.py` | mono→multi 派生 | **不**作默认质检手段；DWS 直接维护 multi |
-
-结论：**DWS-native mono↔multi 质检**；悟空仅参考检查维度。
-
----
-
-## 2. Diff（内容组织 + 质检视角）
-
-### 2.1 已同构
-
-Flat `dingtalk-*` + `dingtalk-shared`；`SKILL.md` + `references/`（+ 可选 `scripts/`）。
-
-### 2.2 分叉与已知内容风险（质检要盯的）
-
-| 风险 ID | 现象（线索） | 质检类型 |
-|---|---|---|
-| **C-cov** | mono `products/*` 能力面在 multi 无对应 skill/reference，或未登记「有意省略」 | 覆盖 |
-| **C-struct** | multi 缺 frontmatter 字段、`references/`、`DWS_RUNTIME_CONTRACT`、对 `dingtalk-shared` 引用不一致 | 结构 |
-| **C-drift-global** | 曾关注 recovery / 确认 / Schema；现确认与 Schema 已在 `dingtalk-shared`，**recovery skill 文档已删除** | 漂移（协议） |
-| **C-drift-orphan** | multi（或 mono）scripts/refs 无文档引用；或 routing 指向无索引产品（留档 X1/M6） | 漂移（孤儿） |
-| **C-pair** | 应对齐的成对文件（如 whiteboard recipes）内容不一致 | 漂移（成对） |
-
-### 2.3 Reject
-
-悟空安装包校验整文件照搬、内容集 19→12 砍产品、安装行为门禁冒充内容质检。
-
----
-
-## 3. Goals / Non-goals
-
-### 3.1 Goals
-
-1. 固化 multi **内容目录合同**与 mono↔multi **映射说明**。  
-2. 建立 **质检矩阵**（覆盖 / 结构 / 漂移）并以 mono 为对照基准；有意省略必须 reviewed 登记。  
-3. **复用** §1.5 资产；新增门禁走 `scripts/policy` 或 `test/unit`，内容-only。  
-4. （可选）纯内容元数据；**禁止**被安装引擎读取改行为。  
-5. 质检失败 → 修 **内容**或更新「有意省略」表，不改 setup/upgrade。
-
-### 3.2 Non-goals
-
-安装/升级翻转；cherry-pick 行为提交；取消产品；悟空客户端；非 skill CLI 功能；用质检驱动默认 multi 安装。

-| **验收** | `make skill-mono-multi-content` 绿；已知缺口走 reviewed omit |
-
-### Phase 4 — 可选：内容包元数据 + 缺口修复波次

+ *                                 NOT the real skills/ tree)
+ *
+ * Scenarios (each with an isolated fake HOME):
+ *   1. multi install        — dingtalk-* and dws-shared land as sibling
+ *                             skills, mono leftover dws/ and stale

+ *                             ~/.dws/skills/{multi,mono} caches fill.
+ *   2. empty multi/ tree    — warns and falls back to mono instead of
+ *                             crashing postinstall; a previously good multi
+ *                             cache is NOT wiped.
+ *   3. bogus mode           — DWS_SKILL_MODE=bogus exits non-zero with an
+ *                             "invalid DWS_SKILL_MODE" error.
+ *   4. multi-only zip, mono — mono install is skipped with a warning; the
+ *                             staging root is NOT copied into a dws/ dir.
+ *   5. multi backup failure — preserves mono, writes no multi skill, and
+ *                             reports postinstall failure.
+ *   6. mono backup failure  — preserves multi, writes no mono skill, and
+ *                             reports postinstall failure.
+ *   7. mono switch          — migrates only centrally owned multi Skills.
+ *   8. cache copy failure   — preserves the previous complete cache.
+ *   9. multi publish failure — restores the complete previous Skill set.
+ *  10. multi backup failure  — restores every earlier successful backup.
+ *  11. mono transaction failure — restores every managed multi Skill after
+ *                                 later backup or mono publish failure.
+ *
+ * Requirements: unix host with tar/zip/unzip on PATH (the same tools
+ * install.js itself shells out to). Skips cleanly on win32.
