+3. 目标创建后记录返回 token；只允许把 `created_by_plan:<create_target plan_id>` 引用解析为该 token，并把解析后的实际参数写入 `execution_journal`。不得重新搜索或猜测目标。
+4. 目标 token 引用解析成功后再移动依赖该目标的资源；解析失败时停止依赖该创建目标的移动并记录 blocker，不得替换为其他目标。
+5. 执行任何写操作前，基于每个已确认计划项的 `rollback_input` 生成 `rollback_snapshot`。`rollback_supported=false` 且已有明确 `rollback_blocker` 的快照视为完整风险快照，不阻塞其他项。
+6. 执行任何写操作前，初始化 `execution_journal`。
+7. 每次写操作尝试后记录 `execution_journal`。
+8. 单项失败后可继续执行相互独立的移动；目标创建失败时必须停止。
+9. 不得移动 `permission_denied`、`no_move_permission`、`move_permission_unknown`、`unverifiable`、`low` 或 `unsupported_move_target` 项。
+10. 不得移动 `move_permission_state!=movable` 或 `target_write_state!=confirmed` 的资源。
+11. 如果移动命令返回权限错误，记录失败原因，不自动申请权限，不自动重试同一移动。
+12. 如果 `rollback_supported=true` 但 `rollback_input` 缺少恢复所需字段，将该计划项标记为 `failed` / `plan_snapshot_incomplete` 并跳过；不得在未重新确认风险的情况下把它静默降级为不可恢复项，也不得阻塞其他独立项。
+
+### 移动方式选择
+
+| 来源 -> 目标 | 移动方式 |
+|------------------|-------------|
+| Drive resource -> Drive folder | `drive +move` |
+| Drive document-like resource -> Wiki target | `wiki +move` 的 docs-to-wiki 模式；默认不可自动恢复 |
+| Wiki node -> Wiki target | `wiki +move --node-token` |
+| Wiki node -> Drive folder | `wiki +move-to-drive` |
+
+### 执行顺序
+
+1. 如有 `create_target` 项，先执行。
+2. 按确认计划顺序执行 `move_resource` 项。
+3. 如果命令返回 task ID，执行异步任务轮询。
+4. 输出写操作执行摘要。
+
+### 进度 UI
+
+批量较大时，按计数汇报进度：
+
+```text
+执行进度：已完成 <done_count>/<total_count>，成功 <success_count>，失败 <failed_count>。
+当前操作：<title>
+继续执行中，不需要你操作；如遇到需要确认的失败会单独提示。
+```
+
+## 状态：`VERIFY`
+
+进入条件：执行完成。
+
+必须：
+
+1. 如果创建了目标，验证目标存在。
+2. 能力支持时，验证已移动资源在目标位置可见。
+3. 对比实际位置和 `move_plan_items`。
+4. 为每一项标记验证状态。
+5. 只有当已有移动成功且存在严重不一致或失败时，才提供恢复选项。
+6. 输出验证结果时，必须说明用户下一步可以结束流程、查看失败项，或在可恢复时选择恢复。
+7. 如果出现 `async_pending`，先使用 `drive +task_result` 轮询确认；超过轮询限制后再报告 pending blocker。
+
+### 验证结果
+
+| 状态值 | 说明 |
+|--------|------|
+| `verified` | 资源已在目标位置可见。 |
+| `not_found` | 目标位置未找到资源。 |
+| `permission_unknown` | 当前身份无法确认结果。 |
+| `async_pending` | 异步任务尚未完成，需要继续轮询。 |
+| `failed` | 移动命令失败或结果不符合计划。 |
+
+## 状态：`RESTORE`
+
+进入条件：失败、不一致或用户明确要求恢复。
+
+必须：
+
+1. 只基于 `rollback_snapshot` 和 `execution_journal` 生成恢复计划。
+2. 展示可恢复项和不可恢复项。
+3. 执行恢复写操作前请求明确确认；确认内容必须包含反向移动和删除本次 workflow 新建目标。
+4. 只恢复本次 workflow 移动过的资源。
+5. 只恢复 `rollback_supported=true` 且 `rollback_eligible=true` 的移动项。
+6. Drive / Wiki 跨容器移动、原父级 token 缺失等 `rollback_supported=false` 的项不得反向移动，也不得删除迁入后的文档。
+7. 本次 workflow 成功创建的目标文件夹或 Wiki 节点必须纳入清理计划。
+8. 删除 workflow 新建的 Wiki 目标节点时，必须使用 `wiki +node-delete --include-children=false --yes`，让已迁入的直接子文档保留到该节点父级层级。
+9. 删除 workflow 新建的 Drive 文件夹前，必须先恢复或移出其中由本次 workflow 放入的资源；如果无法确认文件夹已安全可删，报告清理阻塞，不得用删除文件夹来删除用户资源。
+
+### 恢复顺序
+
+1. 先恢复 `rollback_supported=true` 且 `rollback_eligible=true` 的移动项。
+2. 对全部 `rollback_supported=false` 的项，只记录“保留在当前目标位置，不回迁、不删除”和对应 blocker。
+3. 再清理 `created_by_workflow=true` 的目标容器。
+4. Wiki 新建目标清理使用 `--include-children=false`；Drive 新建目标清理只在不会删除用户资源时执行。
+
+### 恢复 UI
+
+```text
+可以尝试恢复本次已移动的资源：
+
+可恢复：
+- 标题｜当前位置｜原位置
+
+不可自动恢复：
+- 标题｜当前位置｜原位置｜原因｜影响：需要手动恢复

+# 主题资料收集工作流：召回
+
+由状态 `SEARCH_RECALL`、`RECALL_ENHANCE` 加载。
+
+本文档负责基础搜索召回、覆盖增强、query 证据、去重和 `CandidateItem`。不得解析目标移动 token、读取完整文档内容、判断相关性或执行写操作。
+
+本文档只服务 `topic_move_collector`。进入本文档时，`workflow_id` 必须是 `topic_move_collector`；不得把当前任务改路由到其他 workflow。
+
+## 必读上下文
+
+执行本文档规则前：
+
+1. 按 [`../../lark-shared/SKILL.md`](../../lark-shared/SKILL.md) 处理身份、认证和权限。
+2. 按 [`lark-drive-search.md`](lark-drive-search.md) 处理 `drive +search` 语法、过滤条件、单批最多 5 页和身份语义；本 workflow 的全量续批规则见下文。
+
+## 搜索原则
+
+1. 默认使用 `drive +search --mine` 召回当前用户 owner / 负责的 Workspace 资源。
+2. 除非用户本来就要求限定范围，否则不要要求用户指定文件夹或 Wiki 范围。
+3. `SEARCH_RECALL` 和 `RECALL_ENHANCE` 必须保持为独立状态。
+4. `SEARCH_RECALL` 使用用户原始关键词、`owner_scope` 和显式限制。
+5. `RECALL_ENHANCE` 可以基于基础召回证据增加扩展 query，且必须继承同一个 `owner_scope`。
+6. 每个候选项必须保留 query 证据，方便后续解释来源。
+7. 单页或单个最多 5 页的 query 批次不代表完整覆盖；`has_more=true` 时必须保存 `next_page_token` 并自动开始下一批，直到 `has_more=false` 或出现阻塞。
+8. 召回和增强召回可能耗时较长，执行超过 60 秒时必须输出进度提示，之后约每 60 秒提示一次。
+9. 只有用户在 `CONFIRM_CONTEXT` 明确确认 `owner_scope=all_visible` 时，才允许移除 `--mine`。
+
+### 分页优先级与完成语义
+
+1. 用户确认进入 `topic_move_collector` 即表示同意为本次收集任务执行完整召回；无需再要求用户额外说“全部 / 全量 / 继续翻”。本规则覆盖 `lark-drive-search.md` 的默认首屏交互规则。
+2. 仍遵守 `lark-drive-search.md` 的单轮最多 5 页限制。每读取最多 5 页形成一个批次；批次结束且 `has_more=true` 时，保存 checkpoint，并使用原 query、原过滤条件和返回的 `next_page_token` 自动开始下一批。
+3. 自动续批不改变 workflow 状态，也不触发用户确认。执行超过约 60 秒时只输出进度。
+4. 一个 query 只有在 `has_more=false` 时才是 `complete`。单批结束、达到 5 页或已有部分候选都不代表完成。
+5. 当前状态的全部 query 都为 `complete` 后，才能进入下一状态。认证、权限、无效分页 token、连续重试失败或工具预算不足属于 blocker；必须保留 checkpoint、报告部分召回并停在当前状态，不得把部分结果当成完整召回继续分类。
+
+### QueryRecallState
+
+每个基础 / 增强 query 必须维护：
+
+```json
+{
+  "query_id": "稳定 query ID",
+  "query": "完整 query",
+  "recall_stage": "search_recall|recall_enhance",
+  "page_count": 0,
+  "batch_count": 0,
+  "next_page_token": "下一批起点",
+  "has_more": true,
+  "status": "pending|running|complete|blocked",
+  "blocker": "阻塞原因"
+}
+```
+
+## 状态：`SEARCH_RECALL`
+
+进入条件：用户已确认 `CONFIRM_CONTEXT`。
+
+必须：
+
+1. 基于已确认的 `topic` 构造基础 query。
+2. 应用默认 `owner_scope=mine` 和 `constraints` 中的显式限制。
+3. 不隐式添加 `--folder-tokens` 或 `--space-ids`。
+4. 当 `owner_scope=mine` 时，所有基础 query 必须带 `--mine`。
+5. 当 `owner_scope=all_visible` 时，不带 `--mine`，并记录扩展召回风险。
+6. 除非命令限制要求更低值，否则使用 `--page-size 20`。
+7. 每个基础 query 按每批最多 5 页执行；批次结束仍有更多结果时自动续批，并合并所有页面。
+8. 记录基础统计：query、搜索范围、页数、批次数、收集数量、重复数量、阻塞项。
+9. 只有全部基础 query 的 `status=complete` 且 `has_more=false` 时，才进入 `RECALL_ENHANCE`；出现阻塞时保持在 `SEARCH_RECALL`。
+
+### 召回进度 UI
+
+当 `SEARCH_RECALL` 或 `RECALL_ENHANCE` 持续超过约 60 秒时，输出当前进度：
+
+```text
+搜索进度：当前阶段 <SEARCH_RECALL|RECALL_ENHANCE>，已执行 <query_count> 个 query，已读取 <page_count> 页，收集候选 <raw_count> 项，去重后 <unique_count> 项。继续搜索，不会创建或移动资源。
+```
+
+如果正在执行具体 query，可补充：
+
+```text
+当前 query：<query>
+```
+
+### 基础 Query 规则
+
+| 用户输入 | 基础 Query |
+|------------|----------------|
+| 单个关键词 | 直接作为 `--query`。 |
+| 多个关键词组成一个短语 | 优先按用户输入的短语执行。 |
+| 明确精确短语 | 保留引号。 |
+| 明确排除词 | 保留负向词。 |
+| 没有真实关键词，只有过滤条件 | 使用 `--query ""` 搭配过滤条件。 |
+
+在 `SEARCH_RECALL` 中不得添加同义词、仅标题搜索、仅评论搜索或 OR 扩展。
+
+### 基础召回输出
+
+```text
+基础召回完成：
+- 使用 query：
+- 搜索范围：
+- 应用限制：
+- 收集候选：
+- 去重后候选：
+- 阻塞项：
+
+下一步：继续执行覆盖增强，不需要你操作；不会创建或移动资源。
+```
+
+## 状态：`RECALL_ENHANCE`
+
+进入条件：基础召回完成。
+
+必须：
+
+1. 基于已确认主题和基础召回证据生成增强 query。
+2. 确保增强 query 可解释且不引入明显污染。
+3. 每个增强 query 都必须继承 `owner_scope`；`owner_scope=mine` 时必须带 `--mine`。
+4. 每个 query 都必须按每批最多 5 页处理分页，并自动续批直到 `has_more=false`。
+5. 有稳定去重键时，按稳定去重键合并候选项。
+6. 为每个候选项保留 `source_queries` 和命中证据。
+7. 当 query 不再产生新候选，或出现工具预算 / API 阻塞时，停止增强。
+
+### 召回阶段退出门禁
+
+`RECALL_ENHANCE` 完成后，必须：
+
+1. 确认全部基础和增强 query 的 `status=complete` 且 `has_more=false`，再固化完整 `candidate_items`，包含去重结果、`source_queries`、`match_channels`、`snippets` 和 `dedupe_status`。
+2. 将 `current_state` 设置为 `RESOURCE_RESOLVE`。
+3. 加载 [`lark-drive-workflow-topic-move-collector-resolve-verify.md`](lark-drive-workflow-topic-move-collector-resolve-verify.md)。
+4. 把完整 `candidate_items` 交给 `RESOURCE_RESOLVE`。
+5. 不得直接进入 `RELEVANCE_CLASSIFY`、`PLAN_MOVE` 或展示相关性结果。
+6. 不得用搜索标题、摘要或 query 命中直接生成高 / 中 / 低相关分组。
+
+### 增强策略
+
+| 策略 | 说明 |
+|----------|------|
+| 精确短语 | 对明确短语使用 `"..."` 提高精确命中。 |
+| `intitle:` | 对项目名、客户名、制度名、报表名等标题特征强的主题执行标题召回。 |
+| `--only-title` | 当标题命中更可信时使用。 |
+| `--only-comment` | 当主题可能只出现在评论讨论中时使用。 |
+| 类型拆分 | 对 `docx`、`sheet`、`bitable`、`slides`、`file` 等分类型搜索，减少服务端排序偏差。 |
+| 同义词 / 别名 | 使用业务上明确的同义词、简称、英文名、中文名。 |
+| OR 扩展 | 对同一实体的别名做 OR 扩展。 |
+| 负向词 | 对明显噪声使用 `-term`，但不能排除可能相关的主题词。 |
+
+### Query 证据
+
+每个候选项都要记录：
+
+| 字段 | 说明 |
+|-------|------|
+| `source_queries` | 命中过该资源的 query 列表。 |
+| `match_channels` | 命中位置，如 title、body、comment、metadata。 |
+| `snippets` | 搜索返回的摘要或片段。 |
+| `query_rank` | 资源在各 query 中的相对位置。 |
+| `recall_stage` | `search_recall` 或 `recall_enhance`。 |
+
+## 去重规则
+
+必须：
+
+1. 搜索响应提供 canonical token 时，优先使用 canonical token。
+2. 对 Wiki 结果，不得只按 object token 去重；同一对象可能出现在多个 Wiki 节点中。
+3. token 缺失时，使用 URL 作为 fallback。
+4. 合并重复项时保留所有 query 证据。
+5. 如果无法确定去重是否稳定，保留该项并设置 `dedupe_status=uncertain`。
+
+## CandidateItem
+
+```json
+{
+  "title": "资源标题",
+  "url": "资源链接",
+  "raw_type": "搜索返回类型",
+  "source_queries": ["query"],
+  "match_channels": ["title|body|comment|metadata"],

+  "dedupe_key": "候选去重键",
+  "dedupe_status": "stable|fallback|uncertain",
+  "recall_stage": "search_recall|recall_enhance"
+}
+```
+
+| 字段 | 说明 |
+|-------|------|
+| `title` | 搜索结果标题。 |
+| `url` | 资源访问链接。 |
+| `raw_type` | 搜索返回的原始类型。 |
+| `source_queries` | 命中过该资源的搜索 query。 |
+| `match_channels` | 命中位置。 |
+| `snippets` | 摘要或命中片段。 |
+| `page_rank` | 当前 query 下的排序位置。 |
+| `dedupe_key` | 候选去重键。 |
+| `dedupe_status` | 去重可信度。 |
+| `recall_stage` | 资源首次进入候选集的召回阶段。 |
+
+## 阻塞项
+
+缺少认证 / scope、`drive +search` 返回权限或策略阻塞、分页 token 无效、分页重试后仍无法继续，或工具预算不足以完成全部页面时，必须把对应 `QueryRecallState.status` 设置为 `blocked`，保留累计候选、页数和 `next_page_token`，停止并报告。阻塞解除后从 checkpoint 续跑；在全部 query 完成前不得进入资源解析或分类阶段。

+本文档负责资源解析、结构化父级、移动资格、内容验证和 `ResourceItem`。不得判断相关性、生成移动计划、创建目标、移动资源或执行恢复操作。
+
+本文档只服务 `topic_move_collector`。进入本文档时，`workflow_id` 必须是 `topic_move_collector`；不得把当前任务改路由到其他 workflow。
+
+## 必读上下文
+
+执行本文档规则前：
+
+1. 按 [`../../lark-shared/SKILL.md`](../../lark-shared/SKILL.md) 处理身份、认证和权限。
+2. 按 [`lark-drive-inspect.md`](lark-drive-inspect.md) 处理 URL / token 解析。
+3. 使用 `drive metas batch_query` 补齐 Drive 资源 owner、标题和 URL。
+4. 必要时使用 `drive permission.members auth` 读取权限信号；该接口不提供 `full_access` / 移动权限的直接判定，不能把 `manage_public` 等同为可移动。
+5. 按 [`../../lark-wiki/references/lark-wiki-node-get.md`](../../lark-wiki/references/lark-wiki-node-get.md) 处理 Wiki 节点解析。
+6. 按 [`../../lark-doc/references/lark-doc-fetch.md`](../../lark-doc/references/lark-doc-fetch.md) 读取文档内容。
+7. 需要验证 Sheet 内容时，按 [`../../lark-sheets/SKILL.md`](../../lark-sheets/SKILL.md) 执行。
+
+## 进入解析与验证阶段前校验
+
+进入本文档后，如果 `resource_items` 还不存在，当前状态必须是 `RESOURCE_RESOLVE`。
+
+禁止从 `candidate_items` 直接进入 `CONTENT_VERIFY` 或 `RELEVANCE_CLASSIFY`，也禁止从 `RESOURCE_RESOLVE` 直接进入 `RELEVANCE_CLASSIFY`。即使候选项已有标题、URL、摘要或 token，也必须依次执行 `RESOURCE_RESOLVE` 和 `CONTENT_VERIFY`；两个状态不得合并。

+
+进入条件：候选列表已准备。
+
+必须：
+
+1. 为每个 `CandidateItem` 生成稳定 `resource_id`，并转换为标准化 `ResourceItem`。
+2. 解析 canonical token、资源类型、URL、结构化当前父级、Wiki 节点身份和读取权限状态。
+3. 对 Wiki 资源同时保留 `wiki_node_token` 和 `wiki_obj_token`。
+4. 按 `move_method` 补齐 `owner_id`、`is_owner`、`source_move_state`、`source_parent_write_state`、`target_write_state`、`move_permission_state` 和 `move_permission_basis`。

+7. 即使搜索结果已经包含标题、URL 或 token，也必须经过本状态生成 `ResourceItem`；不得从召回结果直接进入相关性分级。
+8. 只有确认 `move_permission_state=movable` 且 `target_write_state=confirmed` 的资源，才能进入后续默认移动链路。
+9. 解析耗时超过约 60 秒时，必须输出进度提示，之后约每 60 秒提示一次。
+
+### 解析规则
+
+| 候选类型 | agent 必须执行 |
+|----------------|---------------|
+| Drive URL / token | token 或类型不确定时，使用 `drive +inspect`。 |
+| Wiki URL / token | 使用 `drive +inspect` 或 `wiki +node-get`；保留节点身份和对象身份。 |
+| 文件夹候选 | 标记为容器；不要当作普通文档做内容验证。 |
+| 快捷方式候选 | 能解析源资源时解析源资源；同时保留快捷方式身份。 |
+| 无读取权限 | 保留可见元数据，并设置 `permission_state=denied`。 |
+| 无移动权限或移动权限未知 | 保留可见元数据和召回证据，并设置对应 `move_permission_state`。 |
+| 无法解析当前父级 | 设置 `current_parent_kind=unknown`，保留已知路径，后续计划项设置 `rollback_supported=false` 和明确 blocker；不得编造父级 token。 |
+
+### 资源解析进度 UI
+
+当 `RESOURCE_RESOLVE` 持续超过约 60 秒时，输出当前进度：
+
+```text
+资源解析进度：已解析 <resolved_count>/<total_count> 项，已确认可移动 <movable_count> 项，无移动权限 <denied_count> 项，移动权限未知 <unknown_count> 项，解析失败 <failed_count> 项。
+当前资源：<title>
+继续解析中，不会创建或移动资源。
+```
+
+如果正在处理权限或 owner 元数据，可补充：
+
+```text
+当前步骤：解析 owner / 当前父级 / 移动资格。
+```
+
+`RESOURCE_RESOLVE` 完成后，输出摘要：
+
+```text
+资源解析完成：
+- 候选总数：N 项
+- 可进入内容验证：N 项
+- 无移动权限：N 项
+- 移动权限未知：N 项
+- 解析失败或无读取权限：N 项
+
+下一步会对可移动资源做内容验证；不会创建或移动资源。
+```
+
+### 资源解析出口门禁
+
+`RESOURCE_RESOLVE` 完成后必须：
+
+1. 将 `content_verify_completed` 重置为 `false`。
+2. 将下一状态设置为 `CONTENT_VERIFY`，不得设置为 `RELEVANCE_CLASSIFY` 或 `PLAN_MOVE`。
+3. 不得在本状态生成 `relevance`、`relevance_groups` 或移动计划。
+4. 即使可读取正文的资源数量为 0，也必须进入 `CONTENT_VERIFY`，为每项记录跳过验证原因并输出验证摘要。
+
+### 移动资格判定
+
+`owner` 只能作为部分权限证据，不得单独把资源判为 `movable`。`RESOURCE_RESOLVE` 必须先按 `move_method` 记录以下独立状态：
+
+| 字段 | 说明 |
+|------|------|
+| `source_move_state` | 当前身份是否确认可以对源资源执行对应移动；Drive owner 只可作为 Drive 源资源可管理的证据，Wiki 底层资源 owner 不能证明 Wiki 节点可移动。 |
+| `source_parent_write_state` | 当前身份是否确认可编辑源位置；仅 `drive_move` 必须确认，其他移动方式为 `not_required`。 |
+| `target_write_state` | 当前身份是否确认可写目标位置；待创建目标以父级位置的创建 / 写入权限为准。 |
+
+#### 按移动方式的权限矩阵

+| `move_method` | `source_move_state=confirmed` 的证据 | `source_parent_write_state` | `target_write_state` |
+|---------------|--------------------------------------|-----------------------------|----------------------|
+| `drive_move` | 当前用户是可靠解析出的 Drive 资源 owner，或有明确资源可管理证据 | 必须为 `confirmed` | 必须为 `confirmed` |
+| `wiki_move_docs_to_wiki` | 有明确的 Drive 文档直接迁入权限；仅 owner 元数据不足以证明可直接迁入 | `not_required` | 必须确认目标 Wiki 节点 / 空间可写 |
+| `wiki_move_node` | 有明确的 Wiki 节点 / 源空间移动权限；不得从底层资源 owner 推导 | `not_required` | 必须确认目标 Wiki 节点 / 空间可写 |
+| `wiki_move_to_drive` | 有明确的 Wiki 节点移出权限；不得从底层资源 owner 推导 | `not_required` | 必须确认目标 Drive 文件夹可写 |
+
+#### 聚合顺序
+
+1. 目标方向或资源类型不支持时，设置 `move_permission_state=denied`、`move_permission_basis=["unsupported_direction"]`。
+2. 任一必需状态为 `denied` 时，设置 `move_permission_state=denied`，并在 `move_permission_basis` 记录 `source_denied`、`source_parent_denied` 或 `target_denied`。
+3. 任一必需状态为 `unknown` 时，设置 `move_permission_state=unknown`，并记录对应的 `source_unknown`、`source_parent_unknown` 或 `target_unknown`。
+4. 只有权限矩阵中的全部必需状态都为 `confirmed` 时，才能设置 `move_permission_state=movable`、`move_permission_basis=["permission_matrix_confirmed"]`。
+
+注意：
+
+1. `drive permission.members auth` 不提供 `full_access` 或 `move` action；不能用 `view`、`edit`、`share` 或 `manage_public` 结果推断源位置或目标位置可写。
+2. `target_write_state=unknown|denied` 的资源不得进入高 / 中相关可执行分组或移动计划。
+3. `move_permission_state=unknown` 的资源默认不进入内容验证、相关性高 / 中分组或移动计划。
+4. 当 `owner_scope=mine` 但解析出的 owner 不是当前用户时，将该资源视为异常候选，设置 `source_move_state=unknown` 和 `move_permission_state=unknown`，不得加入移动计划。
+
+## 状态：`CONTENT_VERIFY`
+
+进入条件：资源列表已准备。
+
+必须：
+
+1. 本状态不可跳过，也不得与 `RESOURCE_RESOLVE` 或 `RELEVANCE_CLASSIFY` 合并；没有可读取正文的资源时仍须执行。
+2. 只在资源解析后读取支持的内容。
+3. 按数量、大小和类型能力限制读取范围。
+4. 结合搜索证据和内容证据；除非标题精确且足够强，否则不要仅凭标题判为高相关。
+5. 将不可读取资源标记为 `unverifiable` 或 `permission_denied`。
+6. 不得自动申请权限。
+7. 为每个资源写入验证状态：已读取内容证据、仅可使用搜索证据、无权限、无移动权限、移动权限未知、无法验证或不支持内容验证。
+8. 对 `move_permission_state=denied|unknown` 的资源，不再读取正文内容，写入跳过验证原因并保留召回证据；写入跳过原因属于执行本状态，不等于跳过本状态。
+9. 所有资源都有验证状态或跳过原因后，将 `content_verify_completed` 设置为 `true` 并输出验证摘要。
+10. `content_verify_completed=true` 前不得进入 `RELEVANCE_CLASSIFY`。
+
+### 验证方式
+
+| 资源类型 | 验证方式 |
+|---------------|---------------------|
+| `docx` / `doc` | 允许时使用 `docs +fetch --api-version v2`。 |
+| `sheet` | 使用 `sheets +find` 查关键词证据，或用 `sheets +read` 读取有界范围。 |
+| `bitable` | 只有必要且已加载 Base 能力时验证。 |
+| `slides` | 除非具备幻灯片读取能力，否则使用元数据 / 预览 / 标题证据。 |
+| `file` | 仅在支持时使用标题、元数据、预览或导出文本。 |
+| `wiki` 节点 | 按 `obj_type` 验证底层对象；节点本身不是内容 token。 |
+| `folder` | 除非用户明确要移动容器，否则通常不作为主题证据移动。 |
+
+### 内容验证完成 UI
+
+完成 `CONTENT_VERIFY` 后必须输出：
+
+```text
+内容验证完成：
+- 已读取内容证据：N 项
+- 仅复用搜索证据：N 项
+- 因无权限或移动资格跳过：N 项
+- 无法验证或不支持验证：N 项
+
+下一步会基于以上证据进行相关性分组；不会创建或移动资源。
+```
+
+如果没有任何资源可以读取正文，仍须输出该摘要，并明确说明所有资源采用的搜索证据或跳过原因。
+
+### 内容验证出口门禁
+
+`CONTENT_VERIFY` 完成后必须：
+
+1. 确认 `content_verify_completed=true`，且每个 `ResourceItem` 都已有验证状态或跳过原因。
+2. 将下一状态设置为 `RELEVANCE_CLASSIFY`。
+3. 加载 [`lark-drive-workflow-topic-move-collector-review-plan.md`](lark-drive-workflow-topic-move-collector-review-plan.md)。
+4. 不得直接进入 `PLAN_MOVE`。

+# 主题资料收集工作流：审核与计划
+
+由状态 `RELEVANCE_CLASSIFY`、`PLAN_MOVE` 加载。
+
+本文档负责相关性分级、审核 UI、移动计划生成和 `MovePlanItem`。不得重新执行资源解析或内容验证，也不得创建目标、移动资源或执行恢复操作。
+
+本文档只服务 `topic_move_collector`。进入本文档时，`workflow_id` 必须是 `topic_move_collector`；不得把当前任务改路由到其他 workflow。
+
+## 输入契约
+
+进入本文档前必须已有：
+
+1. `resource_items`，且每个 `ResourceItem` 已包含稳定 `resource_id`、资源类型、移动所需 token、结构化当前父级、权限状态、内容验证状态和证据。
+2. `content_verify_completed=true`。
+3. 每个资源都有内容证据、搜索证据复用说明或明确跳过原因。
+
+`ResourceItem` schema 和字段生成规则由 [`lark-drive-workflow-topic-move-collector-resolve-verify.md`](lark-drive-workflow-topic-move-collector-resolve-verify.md) 负责。只要上述输入契约完整，本状态不得为重复读取 schema 而重新加载或执行前一阶段文档。
+
+如果输入字段缺失、资源需要重新解析或用户要求重新读取证据，废弃受影响的相关性和计划结果，返回 `RESOURCE_RESOLVE` 或 `CONTENT_VERIFY`，并加载资源解析与内容验证文档；不得在本状态补猜。
+
+## 状态：`RELEVANCE_CLASSIFY`
+
+进入条件：`CONTENT_VERIFY` 已完成，`content_verify_completed=true`，且每个 `ResourceItem` 都已有验证状态或跳过验证原因。
+
+禁止条件：
+
+1. 只有 `candidate_items`，没有 `resource_items`。
+2. 资源未经过 `RESOURCE_RESOLVE`。
+3. 资源没有 `RESOURCE_RESOLVE` 写入的移动资格状态。
+4. 资源没有 `CONTENT_VERIFY` 写入的验证状态或跳过验证原因。
+5. 上一完成状态是 `RESOURCE_RESOLVE`，或 `content_verify_completed` 不为 `true`。
+
+必须将每个资源归入且只归入一个分组：
+
+| 分组 | 说明 | 默认移动 |
+|-------|------|--------------|
+| `high` | 可移动资源，且主题或内容直接命中，有明确标题 / 正文 / 表格 / 评论证据。 | 是 |
+| `medium` | 可移动资源，可能相关，但证据不足或只命中弱相关片段。 | 否，需用户选择 |
+| `low` | 可移动资源，弱相关或噪声，保留展示但不建议移动。 | 否 |
+| `permission_denied` | 当前身份无权读取或解析，不能验证内容。 | 否 |
+| `no_move_permission` | 已确认当前身份不具备移动资格。 | 否 |
+| `move_permission_unknown` | 无法确认当前身份是否具备移动资格。 | 否 |
+| `unverifiable` | 类型或工具限制导致无法验证内容。 | 否 |
+| `unsupported_move_target` | 目标方向或资源类型不支持移动。 | 否 |
+
+`high`、`medium` 和 `low` 只能包含 `move_permission_state=movable` 且 `target_write_state=confirmed` 的资源。
+
+判为高相关至少需要一个强证据：
+
+1. 标题或内容中出现精确主题短语。
+2. 多个主题词在相关上下文中同时出现。
+3. Sheet / 表格单元格明确匹配用户主题。
+4. 用户明确提供的文档名或项目别名命中。
+
+中相关示例：
+
+1. 标题包含一个主题词，但内容无法确认。
+2. 搜索摘要看起来相关，但无法完整读取。
+3. 别名命中合理但证据不够强。
+
+## 审核 UI
+
+必须展示每个分组中的资源名称。
+
+默认展示规则：
+
+1. 展开 `high` 和 `medium`。
+2. 折叠 `low`、`permission_denied`、`no_move_permission`、`move_permission_unknown`、`unverifiable` 和 `unsupported_move_target`，但展示数量并允许展开。
+3. 每个可见资源展示标题、类型、当前位置、证据和默认动作。
+4. 除非用户要求技术细节，否则不展示原始 token。
+
+示例：
+
+```text
+筛选结果：
+
+搜索范围：<当前用户 owner / 负责的资源 | 所有当前身份可见资源>
+
+高相关（默认移动）：
+- 标题｜类型｜证据｜当前位置
+
+中相关（需你勾选后才移动）：
+- 标题｜类型｜证据｜当前位置
+
+未默认移动：
+- 低相关：N 项
+- 无权限：N 项
+- 无移动权限：N 项
+- 移动权限未知：N 项
+- 无法验证：N 项
+- 不支持移动：N 项
+
+你可以选择：
+1. 确认按默认规则生成移动计划。
+2. 勾选要加入计划的中相关资源。
+3. 要求把某些资源移到其他分组或从计划中移除。
+4. 展开低相关 / 无权限 / 无移动权限 / 移动权限未知 / 无法验证 / 不支持移动分组查看名称。
+```
+
+### 用户调整规则
+
+如果用户不同意相关性结果，必须基于用户要求更新 `relevance_groups`，再重新展示分组结果并重新生成后续移动计划。
+
+典型调整包括：
+
+1. 从 `high` 中移除某个资源。
+2. 将 `medium` 中某个资源提升为 `high`。
+3. 将某个资源标为 `low` 或不移动。
+4. 要求重新读取证据或重新判断一批资源。
+5. 要求重新确认某些资源的移动权限。
+
+用户调整后：
+
+1. 旧的 `move_plan_items` 立即失效。
+2. 必须先输出“调整后相关性结果”，展示被调整项、各分组数量和高 / 中相关资源名称。
+3. 不得只回复“已调整”，也不得直接跳到 `CONFIRM_EXECUTION`。
+4. 必须基于新的 `relevance_groups` 重新执行 `PLAN_MOVE`。
+5. 不得把 `no_move_permission` 或 `move_permission_unknown` 资源直接提升到 `high` / `medium`；必须先回到 `RESOURCE_RESOLVE`，加载 [`lark-drive-workflow-topic-move-collector-resolve-verify.md`](lark-drive-workflow-topic-move-collector-resolve-verify.md) 取得可移动证据。
+
+### 调整后结果 UI
+
+```text
+已按你的要求调整相关性结果：
+- <标题>：<原分组> -> <新分组>
+
+调整后分组：
+
+搜索范围：<当前用户 owner / 负责的资源 | 所有当前身份可见资源>
+
+高相关（默认移动）：N 项
+- 标题｜类型｜证据｜当前位置
+
+中相关（需你勾选后才移动）：N 项
+- 标题｜类型｜证据｜当前位置
+
+未默认移动：
+- 低相关：N 项
+- 无权限：N 项
+- 无移动权限：N 项
+- 移动权限未知：N 项
+- 无法验证：N 项
+- 不支持移动：N 项
+
+接下来会基于这个调整后的结果重新生成移动计划；你也可以继续调整。
+```
+
+## 状态：`PLAN_MOVE`
+
+进入条件：相关性分组已准备。
+
+必须：
+
+1. 当 `target_location.create_required=true` 时，纳入目标创建计划。
+2. 生成移动计划前，比较规范化的当前父级与目标父级；已在目标位置的资源生成 `skip_resource`，设置 `skip_reason=already_at_target`，不得生成移动命令。
+3. 默认纳入全部 `high`、`move_permission_state=movable` 且 `target_write_state=confirmed` 的资源。
+4. 只有用户明确选择时，才纳入 `medium`、`move_permission_state=movable` 且 `target_write_state=confirmed` 的资源。
+5. 默认排除 `low`、`permission_denied`、`no_move_permission`、`move_permission_unknown`、`unverifiable` 和 `unsupported_move_target`。
+6. 为每个跳过项生成 `skip_reason`。
+7. 为每个计划项生成稳定 `plan_id`，并使用 `resource_id` 连接对应资源；不得按标题或临时 token 猜测关联。
+8. 按 `command_family` 保存完整、不可变的 `command_args`；不得把 Wiki 底层对象 token 当作 Wiki 节点移动 token。
+9. 为每个 `move_resource` 项复制执行前恢复所需的完整 `rollback_input`，使确认计划不依赖运行时回查 `ResourceItem`。
+10. 当前父级无法结构化解析或属于 Drive / Wiki 跨容器移动时，设置 `rollback_supported=false` 和明确 `rollback_blocker`；该单项仍可进入确认，但必须逐项展示不可恢复风险，不得阻塞其他独立项。
+11. 停止并等待用户选择或执行意图。
+12. 不得为 `move_permission_state!=movable` 或 `target_write_state!=confirmed` 的资源生成 `move_resource` 计划项。
+
+### 已在目标位置判定
+
+1. `drive_move` 比较 `current_parent_kind` 和目标 Drive 父级，并比较规范化后的 `current_parent_token` / root 标识。
+2. `wiki_move_node` 比较 `current_parent_space_id`、`current_parent_kind` 和 `current_parent_token`；Wiki 空间根节点使用明确的 root 标识，不得用空字符串和未知状态混淆。
+3. 只有父级类型、space ID（适用时）和 token 都已解析且相等时，才能设置 `skip_reason=already_at_target`；父级未知时不得猜测为相等。
+
+### 移动 token 选择
+
+| `command_family` | `command_args` 必须包含 |
+|------------------|---------------------------|
+| `drive +move` | `file_token`、`type`、`folder_token`；移动到 Drive root 时显式记录 `folder_token` 为空且目标类型为 root。 |
+| `wiki +move`（node） | `node_token`，以及 `target_space_id` 或 `target_parent_token`；可选 `source_space_id`。不得使用 `wiki_obj_token` 代替 `node_token`。 |
+| `wiki +move`（docs-to-wiki） | `obj_type`、`obj_token`、`target_space_id`、可选 `target_parent_token`，并显式保存 `apply=false`。 |
+| `wiki +move-to-drive` | `node_token`、`folder_token`；移动到 Drive root 时显式记录 `folder_token` 为空。 |
+| `drive +create-folder` | `name`、父级 `folder_token`；创建在 Drive root 时显式记录父级为空。 |
+| `wiki +node-create` | `space_id`、`title`、`obj_type`、可选 `parent_node_token`。 |
+| `none` | 不执行命令，保留 `skip_reason`。 |
+
+目标由本次 workflow 创建时，对应目标参数保存 `created_by_plan:<create_target plan_id>` 引用。`EXECUTE` 只允许把该引用替换为对应创建计划返回的 token；不得重新搜索或猜测目标。
+
+### 计划 UI
+
+```text
+移动计划已生成：
+- 默认将移动高相关：N 项
+- 你已选择中相关：N 项
+- 其中不可自动恢复：N 项
+- 已在目标位置：N 项
+- 不会移动：N 项
+- 无移动权限：N 项
+- 移动权限未知：N 项
+
+你可以回复“确认执行”，也可以继续调整分组、增减中相关资源，或取消本次移动。

+# 主题资料收集工作流
+
+Workflow id: `topic_move_collector`
+
+Risk / Structure: `R2-R3` / `S3`
+
+本文档实现已注册的主题资料收集 workflow。执行前必须先阅读 [`lark-drive-workflow.md`](lark-drive-workflow.md) 和 [`../../lark-shared/SKILL.md`](../../lark-shared/SKILL.md)，并遵循共享执行协议、Artifact Contract、Workflow Loading、认证和写入确认规则。
+
+本文档负责定义本 workflow 的全局约束、状态机和渐进加载关系。具体阶段规则放在配套文档中，只有进入对应状态时才加载。
+
+配套文档只是本 workflow 的引用文件，不是独立 skill。不要把用户请求直接路由到某个配套文档。
+
+## 必读上下文
+
+执行本 workflow 前，必须先阅读 [`../../lark-shared/SKILL.md`](../../lark-shared/SKILL.md)，用于处理身份、认证、权限和写操作确认规则。
+
+按阶段渐进加载其他 skill / 引用文档：
+
+- 目标是 Wiki 或个人文档库：[`../../lark-wiki/SKILL.md`](../../lark-wiki/SKILL.md)
+- 需要读取文档内容：[`../../lark-doc/SKILL.md`](../../lark-doc/SKILL.md) 和 [`../../lark-doc/references/lark-doc-fetch.md`](../../lark-doc/references/lark-doc-fetch.md)
+- 需要验证 Sheet 内容：[`../../lark-sheets/SKILL.md`](../../lark-sheets/SKILL.md)
+- 需要 Drive 搜索：[`lark-drive-search.md`](lark-drive-search.md)
+- 需要资源解析：[`lark-drive-inspect.md`](lark-drive-inspect.md)
+
+## 适用范围
+
+本 workflow 用于根据用户给出的主题、关键词或内容线索，在云空间 / 云盘 / Wiki / 电子表格等 Workspace 资源中查找相关资料，并在用户确认后统一移动到指定 Drive 文件夹或 Wiki 节点下。
+
+适用触发语包括：
+
+- "帮我找到和某主题相关的文档并放到这个文件夹"
+- "把所有关于某项目的资料收集到知识库节点下"
+- "找出包含某内容的资料，确认后移动到新建目录"
+- "按这个关键词搜索我负责的资料，把相关资料归档"
+
+默认搜索范围是当前用户 owner / 负责的 Workspace 资源，即 `owner_scope=mine`。只有用户明确要求“不限 owner”“包括共享给我的”“所有我能看到的文档”或“全量搜索”时，才使用 `owner_scope=all_visible` 进入扩展召回模式。
+
+不要求用户先限定文件夹或知识库范围。只有用户明确指定范围时，才使用 `--folder-tokens`、`--space-ids` 或其他显式限制。
+
+## 非目标
+
+默认不生成：
+
+- 长篇研究报告
+- 内容总结文档
+- Sheet 清单或统计看板
+- 自动权限治理报告
+
+默认禁止执行：
+
+- 未确认前创建文件夹或 Wiki 节点
+- 未确认前移动资源
+- 删除资源、重命名资源或修改公开权限
+- 自动批量申请权限
+- 把无权限或无法验证的资源加入移动计划
+- 把移动权限未知或不具备移动资格的资源加入移动计划
+
+如果用户明确要求把结果写入 Sheet / Doc，切到对应专项能力；本 workflow 的默认产物是移动后的资源归档结果。
+
+## Agent 执行约束
+
+触发本 workflow 后，agent 必须：
+
+1. 按“执行状态机”的顺序执行。
+2. 维护“运行时状态”中的字段。
+3. 执行某个状态前，先读取本文档 `## 渐进加载关系` 表格中该状态对应的文档。
+4. 用户可见说明、字段说明和 UI 文案使用中文。
+5. 状态名、字段名、枚举值、命令名保留英文稳定标识。
+6. 将 `CONFIRM_CONTEXT` 和 `CONFIRM_EXECUTION` 作为强用户确认门：前者确认主题、目标位置、身份、搜索范围、可选限制和目标解析结果后才能搜索；后者确认创建目标和移动资源后才能写入。
+7. 进入 `EXECUTE` 前，不得创建目标文件夹 / 节点，也不得移动资源。
+8. 必须展示每个相关性分组中的资源名称；低置信分组可以折叠，但必须可查看。
+9. 默认只移动 `high` 相关资源；`medium` 资源必须由用户显式选择。
+10. 即使用户可见列表分页展示，也必须维护完整内部状态。
+11. `RESOURCE_RESOLVE` 和 `CONTENT_VERIFY` 是两个独立的强制阶段，不得合并；不得用搜索结果、标题或摘要直接替代 `CONTENT_VERIFY`，也不得从 `RESOURCE_RESOLVE` 直接进入 `RELEVANCE_CLASSIFY`。
+12. 触发后锁定 `workflow_id=topic_move_collector`；执行期间不得自动切换到其他 workflow。
+13. 如果认为需要切换 workflow，必须停止并向用户说明原因，等待用户确认。
+14. `RESOURCE_RESOLVE` 是移动资格门禁；只有确认 `move_permission_state=movable` 且 `target_write_state=confirmed` 的资源才能进入默认移动链路。
+
+## 用户展示 UI 规则
+
+所有用户可见 UI 都必须包含：
+
+1. 已经完成的关键结果。
+2. 下一步会做什么，以及是否会产生写操作。
+3. 如果 `wait_for_user=true`，明确告诉用户可以选择的动作。
+4. 如果无需用户操作，明确说明将继续执行，避免用户误以为流程停住。
+
+典型动作包括：确认继续、修改主题 / 目标 / 限制、展开更多结果、调整相关性分组、选择中相关资源、确认执行、取消执行。

+## 运行时状态
+
+本 workflow 扩展共享 Artifact Contract。agent 在一次 workflow 运行中必须维护以下专项内部字段：
+
+| 字段 | 说明 |

+| `DONE` | `done` | 无后续操作 | 停止 | 最终回复 | `false` | 结束 |
+
+### 状态跳转硬约束
+
+1. `RESOLVE_TARGET` 只有在 `target_resolve_status=resolved` 时才能进入 `CONFIRM_CONTEXT`；`ambiguous`、`unsupported` 或 `permission_denied` 必须保持在 `RESOLVE_TARGET` 并等待用户选择、更换目标或结束。
+2. `SEARCH_RECALL` 只有在全部基础 query 的 `has_more=false` 时才能进入 `RECALL_ENHANCE`；单批达到 5 页但仍有更多结果时必须自动续批，不得提前跳转。
+3. `RECALL_ENHANCE` 只有在全部增强 query 的 `has_more=false` 时才能进入 `RESOURCE_RESOLVE`；不得直接进入 `RELEVANCE_CLASSIFY` 或 `PLAN_MOVE`。
+4. `RESOURCE_RESOLVE` 必须为每个 `CandidateItem` 生成对应的 `ResourceItem`，或生成明确的解析失败 / 权限受限状态。
+5. `RESOURCE_RESOLVE` 必须为每个 `ResourceItem` 写入 `move_permission_state` 和 `move_permission_basis`；完成后将 `content_verify_completed=false`，下一状态只能是 `CONTENT_VERIFY`。
+6. 禁止从 `RESOURCE_RESOLVE` 直接进入 `RELEVANCE_CLASSIFY`。即使没有任何资源可以读取正文，也必须进入 `CONTENT_VERIFY`，为每项写入验证状态或跳过原因并输出验证摘要。
+7. `CONTENT_VERIFY` 必须为每个 `ResourceItem` 写入内容证据、搜索证据复用说明，或不可验证原因；移动权限未知或无移动权限的资源可以只写入跳过验证原因。
+8. 只有当 `resource_items` 已准备、每项都有验证状态或跳过原因，且 `content_verify_completed=true` 时，才能进入 `RELEVANCE_CLASSIFY`。
+9. 用户调整相关性分组后，必须回到 `RELEVANCE_CLASSIFY` 输出调整后的分组结果，再进入 `PLAN_MOVE` 重新生成计划。
+
+### Workflow 切换门禁
+
+只有以下情况允许考虑切换 workflow：
+
+1. 用户明确说不再做主题资料收集，改为整理整个目录结构或生成盘点方案。
+2. 当前 workflow 明确无法覆盖用户的新目标。
+3. 用户要求的是目录结构治理，而不是查找主题相关资料并移动。
+
+即使满足以上条件，也不得自动切换；必须先向用户说明原因并等待确认。
