真实协议验收缺少凭证。本文保留设计决策，当前使用说明见 `integrations/external-context-mem0/README.md`，验收明细见 `.qwen/e2e-tests/external-context-mem0-explicit-delete.md`。 + +**日期与基线：** 2026-09-08；调研时 `origin/main` 为

增加管理员单独启用的外部记忆删除入口，支持**读取一个明确目标，再按 ID 删除一条记录**。采用无状态的两个工具：`context_get({ memoryId })` 获取完整目标，`context_forget({ memoryId, expectedContent })` 经现有权限策略后复核目标并删除。 + +确认正文由模型搬运，但执行端必须从绑定的服务重新读取并核对；模型传入的 ID、正文或“已经确认”声明都不是服务端事实。无需新增确认 token、快照缓存、持久化删除任务或 Core 协议。 + +首版面向已注册、可信的普通 workspace，支持各 workspace 的独立服务绑定。以 Holo 为真实服务验收目标；针对 Holo 只完成公开协议和代码调研，不声明其删除链路已经可用。自动删除、语义匹配后直接删除、批量清空、级联删除、恢复、后台重试、CLI/TUI 接入、Conversations 和跨 workspace cwd 迁移不在首版范围内。本地 `/forget` 继续管理本地 auto-memory。 + +## 2. 实现前核对的事实 + +| 事实 | 设计影响 | +| ------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------ | +| V2 搜索输出把 ID 截断到 128 code point、正文截断到 1000，并为总输出预算继续缩短正文。 | 搜索只能提供候选，不能提供完整删除确认；ID 不能继续静默截断后作为删除定位符。 | +| writer 的 `stored` 返回最长 256 字符的完整 ASCII memory ID；`accepted` 可能只有操作 ID。 | 完整写入回执可提供候选 ID；不将 operation ID 自动转换成 memory ID。 | +| 普通 MCP 的审批在实际执行工具之前发生，审批载荷携带当前完整参数。 | delete handler 内部的 GET

专属确认 Hook。 | +| Holo 文档列出单条 GET/DELETE 使用同一个带记录 ID 的路径，但未给出完整 GET/DELETE 回执或条件删除语义。 | 路径可作为验收起点；不能推断 scope 字段、404、响应正文或原子条件删除行为。 | +| Mem0 Platform 文档的 GET 返回顶层 scope，未找到为 404；当前 OSS server 的 GET

路径依据：[创建和调用长记忆服务](https://www.alibabacloud.com/help/tc/hologres/user-guide/create-and-use-long-memory-service)。Platform 回执依据：[Get Memory](https://docs.mem0.ai/api-reference/memory/get-memory)、[Delete Memory](https://docs.mem0.ai/api-reference/memory/delete-memory)。OSS 依据为固定提交 [dae67f74 的 server](https://github.com/mem0ai/mem0/blob/dae67f74f5cc7bf138c7d7d6f9cec5ce4b4373b3/server/main.py#L443) 和

+```mermaid +sequenceDiagram + participant U as 用户 + participant A as daemon 会话 + participant D as 独立删除 MCP + participant S as 绑定的记忆服务 + U->>A: 删除这条已经过期的项目约定 + A->>D: context_get(memoryId) + D->>S: GET 精确 ID + S-->>D: 记录与真实 scope + D->>D: 校验完整 ID、scope、正文边界 + D-->>A: 完整原文，标记为不可信数据 + A->>U: forget 审批：memoryId + expectedContent + U->>A: 批准本次调用 + A->>D: context_forget(memoryId, expectedContent) + D->>S: GET 同一精确 ID + D->>D: ID、scope、全文一致才继续 + D->>S: 单次 DELETE 同一 ID + S-->>D: 已识别的成功回执 + D->>S: 单次 GET 复核不存在 + D-->>A: deleted / not_deleted / unknown + A-->>U: 删除结果 +``` + +上图采用推荐的人审配置。拒绝或取消审批时，forget handler 尚未执行，没有它的前置 GET，也没有 DELETE；之前独立的 context_get 可能已经读取过目标。没有完整目标、存在多个候选或全文超限时，应先澄清目标或使用服务管理接口，不把搜索摘要当作确认原文。 + +`context_get` 是正常流程中的辅助读取，并非授权前置凭据。用户已经提供完整 ID 和原文时，可以直接请求 forget；forget 自身的完整复核足以保护执行目标。无状态设计不要求证明之前发生过某一次 get。 + +## 4. 工具契约 + +### 4.1 读取目标：context_get + +输入只有 `memoryId`，严格拒绝未知字段。输入及响应 ID、响应正文统一采用 4.2 的边界：1–256 个允许的 ASCII ID 字符，拒绝整段 `.`/`..`；正文允许空白，最多 4000 个 Unicode code point，拒绝未配对 surrogate，不截断或规范化。最多执行一次精确 GET。仅当响应 ID 完全相同、所有配置的 scope 字段都相等且正文能完整处理时，才返回目标；先验证归属，再向模型和客户端暴露正文。 + +成功结果包含 `status: "found"` 和 `untrusted_deletion_target: { notice, memoryId, content }`；失败返回 `status: "unavailable"` 或 `"failed"` 与固定说明，不回显异 scope 内容、服务地址或上游错误。未找到和归属不匹配都可归为 unavailable，不提供跨 scope 存在性探测结果。目标正文始终是数据，不是指令。 + +这是独立的完整目标协议，不复用 V2 搜索的 1000/4000 字符压缩器。annotation 为 `readOnlyHint: true`、`idempotentHint: true`、`destructiveHint: false`、`openWorldHint: true`。其授权仍由现有权限策略决定，不因 read-only annotation 自动授权。 + +### 4.2 删除目标：context_forget + +输入严格限定为 `memoryId` 和 `expectedContent`。不接受 scope、URL、凭证、operationId、query、filters、批量数组、级联选项或 `confirmed: true`。 + +- `memoryId`：1–256 个 ASCII 字符，沿用 writer 的字母、数字、点、下划线、冒号、连字符集合，但必须额外拒绝整段 `.` 和 `..`。禁止空值、百分号、斜线、反斜线、查询、片段和控制字符，不 trim、不规范化、不补全 ID。 +- `expectedContent`：0–4000 个 Unicode code point，拒绝未配对 surrogate，完整保留空白、换行和控制/格式字符。**允许空字符串或纯空白正文**，因为清理错误记录也包括空记忆；不能直接复用 writer 的“正文必须非空白”校验。超过上限明确拒绝，不能截断。 +- 删除前精确 GET：必须核对返回 ID 与输入逐字符相等；所有配置的 user/agent/app scope 均须存在且逐字符相等；完整正文须等于 expectedContent。缺失、类型错误、歧义、模型摘要、Unicode 归一化差异或任何不匹配都产生零 DELETE。 +- annotation 为 `readOnlyHint: false`、`idempotentHint: false`、`destructiveHint: true`、`openWorldHint: true`。HTTP DELETE 的通常幂等语义不能被用作在此 MCP 流程中透明重放的授权。 + +同一输入再次调用是新的显式请求，会重新走当前权限策略和 GET 复核；没有本地去重账本。若记录已不存在，返回 not_deleted，不再发送 DELETE，也不声称它一定由上次调用删除。 + +### 4.3 完整 ID 的来源 + +可使用 writer 的 `stored.memoryId`、完整目标读取结果或管理员明确提供的精确 ID。搜索结果只可用于选择候选，选中后仍应读取完整目标。 + +同一个实现 PR 应修正 Mem0 reader 的 ID 截断：保持其输出 schema 的 128 code point 上限，遇到超长 ID 时跳过该记录，不能返回裁剪后的前缀。正文的现有搜索摘要行为保持不变。长度 129–256 的完整 ID 仍可从 writer 回执或服务管理界面传入 context_get。无需扩大旧读取协议或自动恢复缺失的 ID 后缀。 + +不将 `accepted.providerOperationId` 当记录 ID；删除 API 不增加 operationId 字段。两种 ID 可能使用同一种字符串格式，不能声称仅靠正则就能区分，最终以精确记录读取为准。 + +## 5. 配置与有限协议 + +建议增加同一包内的独立 `dist/delete-main.js`，MCP server 名为 `external-context-mem0-delete`，只暴露 context_get 和 context_forget。管理员显式配置 workspace MCP 的 cwd/env/includeTools，默认 Extension manifest、V2 搜索、V3 Auto Recall、V4 writer 均不改变工具集合。 + +使用独立 `QWEN_EXTERNAL_CONTEXT_MEM0_DELETE_CONFIG` 和严格的 `DeleteInstanceConfigV5`。这里的 V5 仅指 Mem0 删除实例配置版本，不改变 Qwen settings 的版本。选择新入口和新 schema 可独立部署读取、写入、删除权限，避免已经启用 writer 的 workspace 自动获得删除能力。 + +```json +{ + "schemaVersion": 5, + "repositoryRoot": "/workspace/project", + "dialectPath": "/etc/qwen/external-context/delete.dialect.json", + "endpoint": { + "origin": "https://memory.example.com", + "basePath": "", + "allowInsecureHttp": false + }, + "credentialEnv": "MEMORY_DELETE_API_KEY", + "scope": { "userId": "repository-memory" }, + "timeoutMs": 10000 +} +``` + +复用现有的有界配置读取、绝对路径、canonical repository/cwd containment、静态 endpoint 校验及最后读取凭证的顺序。至少固定一个 scope；凭证必须能在同一目标上读取并删除。配置一次加载，重启生效，不从请求、session/client ID 或 cwd 变化动态推导记忆库。 + +有限 `DeleteDialectV1` 的合成示例： + +```json +{ + "deleteDialectVersion": 1, + "id": "organization-memory-delete-v1", + "auth": "authorization-token", + "record": { + "pathPrefix": "/memories/", + "pathSuffix": "", + "idField": "id", + "contentField": "memory", + "notFound": "http-404" + } +} +``` + +这不是 Holo preset。语法只允许以下差异： + +- Auth 复用已有 Token、Bearer、x-api-key 枚举。 +- GET、DELETE 共享同一个记录地址。pathPrefix 是通过现有静态路径校验、以 `/` 结束的绝对路径；pathSuffix 只能为 `""` 或 `"/"`。把已验证的 ID 作为单个路径段进行编码。必须拒绝 `.`/`..`，避免 URL 规范化把单条 DELETE 变成集合 DELETE。禁止请求模板、动态 origin、任意 headers、GET/DELETE body、filters 和批量路径回退。 +- 成功 GET 只接受 HTTP 200 的单个根对象；idField 复用 `id` / `memory_id`，contentField 复用 `memory` / `content` / `text`。scope 只读取服务定义的顶层 user_id、agent_id、app_id，全部已配置字段严格匹配，不从自定义 metadata 猜归属。 +- `record.notFound` 只能为 `http-404` 或 `null-200`，分别匹配 HTTP 404、HTTP 200 且完整 JSON 值为 null。只按选定规则解释；空数组、空对象、缺字段和另一种形状不是“不存在”。 +- 首版只识别同步 DELETE 的 HTTP 200 对象回执，message 必须精确为已核实的两种单条成功文本之一：`Memory deleted successfully` 或 `Memory deleted successfully!`。error/errors 存在且非 null（含空字符串或空数组）、冲突 status/event、非零或非法 cascade_count 都归为 unknown。可接受缺省或 SUCCEEDED status、缺省或 DELETE event；其余未知状态不猜测。其后还须做一次精确 GET 复核。 +- 不支持 202 异步回执、204 空响应、自定义成功表达式、JSONPath、轮询和协议自动探测。取得新的真实契约后再决定是否扩充，不从其他厂商或批量删除文档推导支持。 + +每个配置文件最多 64 KiB；每个 HTTP 响应最多 1 MiB，严格 UTF-8/JSON，有效目标正文再受 4000 code point 上限约束。禁用重定向。timeoutMs 允许 100–30000 ms，forget 的一个总 deadline 覆盖前置 GET、DELETE 和复核 GET，开始于工具实际执行后，不包含人工审批等待。合并调用取消信号，不给每个阶段重新发放完整时间预算。 + +## 6. 结果与请求次数 + +每次 forget 最多一个前置 GET、一个 DELETE、一个成功后的 GET 复核。没有内部重试、预搜索、后台任务或补偿写入。 + +| 状态 | 条件 | 含义 | +| ------------- | ------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------- | +| `deleted` | 已识别的同步成功回执，且紧接的一次精确 GET 按选定协议确认不存在 | 服务确认删除，单条读取已复核；不保证所有索引、备份或历史消息同步清除。 | +| `not_deleted` | 输入/配置不可用、调用在 DELETE 前取消，或前置 GET 失败、找不到目标、scope/正文不匹配 | 本次没有发送 DELETE；使用固定 reason 区分 invalid_input、target_unavailable、target_changed、verification_failed、cancelled。 | +| `unknown` | DELETE 已开始后取消、超时、断线、非预期 HTTP/回执，或成功回执后的 GET 没能确认不存在 | 本次可能已删除；停止，不自动重试，不声称恢复或撤销。 | + +输出包含状态、合法输入的 memoryId 和固定说明；不回显正文、credential、endpoint 或上游 message。not_deleted/unknown 使用 MCP isError；非法 MCP schema 也可能在 handler 前被协议层直接拒绝。 + +DELETE 自身的 404 不能当作“本次删除成功”；成功回执后的 GET 失败也不能借搜索结果为空补成 deleted。若 DELETE 回执未知，立即返回 unknown，不通过后续观察推断是哪一个调用造成的删除。用户可显式发起 context_get 核查，但该读取不追溯证明原请求执行结果。 + +## 7. 审批、信任与并发边界 + +### 7.1 复用 daemon 权限 + +推荐配置为默认审批模式、server `trust: false`、`permissions.ask` 精确匹配 `mcp__external-context-mem0-delete__context_forget`。includeTools 包含 context_get 和 context_forget。context_get 的只读授权单独按管理员现有策略决定；不使用 trust:true 一并放开两个工具。 + +现有 Web Shell 通用参数正文展示 memoryId 和完整 expectedContent，控制/格式字符用可逆转义显示；SDK 客户端读取已有 rawInput。模型伪造或改写原文会导致执行前复核失败，不能因为客户端批准了一个字符串就把它当作真实记录正文。该保证来自执行前比较，并不声称审批 UI 已经认证来源或每次调用都先执行过 context_get。 + +YOLO、普通 allow、PermissionRequest Hook 代批和改参数继续沿用现有语义。修改后的参数仍须通过相同 ID/scope/全文复核，但不能报告成用户已人工确认这些新参数。daemon 客户端回复不支持通过 updatedInput 改写正文；应拒绝后重新发起调用。无新 PreToolUse 确认 Hook，不新增不可绕过的人审模式。 + +### 7.2 明确 GET 与 DELETE 的间隔 + +本版提供的是“删除前核对完整正文，再按 ID 删除该记录”，不是版本原子删除。审批期间发生的正文变化会被执行前 GET 检出；**最后一次 GET 完成后到 DELETE 执行之间的变化仍可能发生**。该 ID 的记录在此间被更新，其最新内容仍可能一同删除。 + +随机 token、客户端内容哈希、进程内锁或多做一次 GET 都不能消除这段远端竞态。若要求删除瞬间必须仍是某一版本，需要服务真正实现 ETag/If-Match 或等价的原子条件删除。本次查阅的 Holo/Platform 文档没有提供该契约，不能直接假设发送 If-Match 就会生效；首版不增加伪条件删除开关。 + +workspace 归属同样不能依靠最后一次 GET 获得原子保证。首版受管部署必须核实记录 ID 不复用，并核实真实 scope 归属不可迁移，或由服务凭证/删除接口独立限制到固定 scope；所选返回 scope 字段必须是服务的真实分区字段，不能是可任意填写的 metadata。无法满足这些条件的服务，不作为多 workspace 安全删除 profile 验收通过，应先补服务端约束。凭证本身仍承担访问授权；scope 配置不是租户 ACL。 + +### 7.3 生命周期与删除后的数据 + +配置和 transport 依赖所属 runtime，继续用 live-session-owner 审批回复和 selected-runtime MCP 管理；不新增 memory REST 路由，不回退 primary。重启配置前结束待处理调用，再使新进程加载新绑定。此无状态方案没有 token TTL 或“进程重启使快照失效”的承诺；不得把已发送或中断的旧调用自动重新发起。 + +REST SSE 断开不等于取消 pending approval，需显式取消 prompt/session；其他传输按已有生命周期处理。取消或 runtime 退出发生在 DELETE 之后时不能撤销远端操作。跨 session/无效/重复/过期投票不能触发新执行，这些路径需要真实 daemon 回归。 + +deleted 不代表服务搜索索引已同步，也不会移除 Qwen 已有 transcript、已发给模型的上下文、服务访问日志或备份。自然语言复述旧信息不等于删除失败；验收应在新客户端/新会话检查实际搜索回执及模型输入。确认全文会进入普通工具参数与会话记录，本功能不新增正文日志、缓存或本地备份。 + +## 8. 实现拆分 + +| 层 | 预计改动 | +| -------------- | ------------------------------------------------------------------------------------------------------------------------------- | +| 独立入口与工具 | 当前包新增 delete-main、delete-mcp、delete-profile，注册完整目标读取及显式删除。 | +| 配置与协议 | 新增 V5/delete dialect schema、类型和 loader，复用已有小型验证助手；保持 V2/V3/V4 严格版本回归。 | +| HTTP | 新增单条读取验证器和 get-check-delete-check 流程；复用认证、有界读取，避免复用会丢弃 scope 的搜索归一化。 | +| 搜索候选 | 修正当前包 profile 的超长 ID 处理：跳过而非裁剪；保留正文摘要和输出 schema。 | +| 展示与宿主 | 预计只新增现有 adapter/ToolApproval 与真实 daemon 回归，不改 Core、ACP 协议或 scheduler。若验证发现缺口，再做有证据的最小修复。 | +| 发布与说明 | 包 build/files 包含独立删除入口、受管 workspace 配置示例和 README；默认 manifest 不启用删除。 | + +按一个聚焦实现 PR 组织上述范围。2026-09-08 经用户授权开展本地实现；真实 Holo 删除和云配置变更尚未执行。 + +## 9. 验收门槛与待确认事实 + +合成测试必须覆盖：候选 ID 不截断、点路径 ID 不得落到集合、空正文删除、scope 与全文复核、模型伪造参数、审批期间变更、单次 DELETE、删除后一次精确复核、未知回执、跨 workspace 隔离、取消与禁止透明重放、真实浏览器完整显示。计划及执行记录位于 `.qwen/e2e-tests/external-context-mem0-explicit-delete.md`；全局 CLI 基线见同目录 `external-context-mem0-explicit-delete-baseline.md`。 + +真实 Holo 验收前先核对当前访问条件。上一轮 2026-09-07 的隔离 scope list 返回 403，create 为零；该旧结果不能代表今天的连通性。2026-09-08 实施预检时，此前临时凭证已不可用，未发送任何真实服务请求；详见 `.qwen/e2e-tests/holo-delete-preflight.json`。 + +Holo 待确认的事实为：精确 GET 的完整 ID/正文/真实 scope 形状，未找到的表示，单条 DELETE 的同步回执、无级联/批量副作用，以及 ID/归属的生命周期保证。确认这些事实后，使用本次新建的合成目标和同/异 scope 对照记录完成拒绝、批准、精确 GET 消失、搜索传播和对照记录不变验证，再按精确 ID 清理。不得删除既有业务记录。 + +服务端协议验收通过后才能宣布 Holo 支持；本地实现和合成 daemon 验收可先独立进行。若 Holo 响应不符合上述有限语法，应据真实证据调整设计，不能用宽泛 2xx 判成功或静默选择另一个路径。 + +## 10. 设计调研基线的代码依据 + +-

Full IDs up to 256 ASCII characters can still come +from a writer's `stored.memoryId` or the service administration interface; do +not substitute `accepted.providerOperationId` or repair an old truncated ID. + +The tool accepts only ASCII letters, digits, dot, underscore, colon and hyphen +in IDs, rejecting the entire IDs `.` and `..`.

Authentication uses the same +three supported headers as search. GET and DELETE share the static prefix plus +one encoded ID segment; suffix is empty or `/`. There are no request bodies, +query parameters, redirects, bulk fallbacks or automatic protocol detection. + +GET must return HTTP 200 with one root object and the selected `id`/`memory_id` +and `memory`/`content`/`text` fields. Every configured scope must exactly match +the authoritative top-level `user_id`, `agent_id` or `app_id`; arbitrary metadata +is not a scope source. Foreign or missing targets do not disclose their text. +The selected absence contract is either HTTP 404 (`http-404`) or HTTP 200 with +JSON null (`null-200`); other shapes are not interpreted as absence. + +DELETE must return HTTP 200 with the exact message `Memory deleted successfully` +or `Memory deleted successfully!`. Optional status must be `SUCCEEDED`, event +must be `DELETE`, and cascade_count must be numeric zero. Non-null error/errors, +conflicting fields, 202, 204 and other unrecognized replies remain unknown. +Responses are bounded to 1 MiB and strictly decoded as UTF-8/JSON. + +### Approval, verification and limits + +Apply [the managed workspace settings example](./examples/managed-daemon-delete-workspace-settings.json), +replacing the absolute paths and supplying the credential through that workspace's +runtime environment.

The read helper follows its own normal +permission policy; read-only annotations are not automatic authorization. + +Web Shell displays the exact ID and full expected text through ordinary MCP +parameter approval. After approval, forget reads the target again and compares +ID, all configured scope fields and full text before submitting one DELETE. +If it receives a recognized success acknowledgement, it performs one exact GET +to verify absence. One total 100–30000 ms deadline covers those three steps; +human approval waiting is outside that deadline. No state, confirmation token +or mandatory earlier get is required: a direct call with the correct full ID +and original text receives the same checks. + +| Result | Meaning | +| ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ | +| `deleted` | Recognized deletion acknowledgement followed by a read confirming absence. | +| `not_deleted` | This call submitted zero DELETE requests.

Non-idempotent destructive annotations +prevent transparent replay; a new explicit call still follows current permissions. +YOLO and PermissionRequest Hook automatic approvals retain their existing +semantics. Client approval replies cannot edit arguments; reject and request a +new call to change them. Pending approval cancellation and runtime ownership use +the existing daemon lifecycle. Disconnecting a REST SSE subscription is not an +explicit cancellation, and cancellation cannot undo an already submitted DELETE. + +The last GET and DELETE are **not atomic**. Changes while waiting for approval +are detected, but an update after the final GET may also be deleted.
