消息反馈

English | 中文

@deepseek-ai/dsh-message-feedback拥有针对单条 assistant 消息的可编辑反馈。权威 Session 日志保存 feedback/message-put 和 feedback/message-delete；不可变的 Session 级备注仍使用 feedback/record。三者都是仅写日志的事件，绝不进入模型上下文。

数据与并发

当前条目由 payload 中 sessionId 与所属 Session 匹配的权威反馈事件归约得到。每个条目携带好评或差评、可选备注、Host 分配的 createdAt/updatedAt 时间戳及自己的 opaque version。version 只能用于相等比较，且只与目标消息比较；调用方不能排序或自行合成它。

put 采用严格乐观并发：已有条目的每次请求都必须匹配当前 ifVersion，即使请求不会改变目标值。冲突会返回权威当前条目（不存在时为 null），因此调用方无需额外读取，即可协调丢失响应或并发编辑。删除已经不存在的条目同样成功。按 Session 划分的队列串行执行读取与变更；cold 变更在读取、比较、追加和 flush 期间持有持久化写句柄。匹配版本的无变更操作不追加事件。

目标与生命周期权威

live 持有者的内存日志直接提供目标 Session 的观测；cold 读取使用 SessionPersistence.open(id, 'read') 句柄，变更则使用写句柄。两条路径都不构造 Session 或 Agent。先由 stat(id) 预检明确不存在；stat 已确认存在的 Session 若读取失败，会按基础设施故障原样传播。put 只接受具有指定 MessageId 的非空、append-origin assistant/message；replacement-origin、仅承载 usage 的空记录和非 assistant 记录都不是反馈目标。

fork 种子可以包含父 Session 的反馈事件，但 payload 保留父级 sessionId，因此不会成为子 Session 的当前反馈。删除条目会追加删除标记；早先的评分与备注仍保留在日志中。

持久化与 Remote 约定

成功的消息反馈变更会等待权威持久化完成：live 操作通过所属 Session 追加，并要求有 ctx.sessions.flush 监听器参与；cold 操作通过写句柄追加并 flush。持久化故障会原样传播，不会报告成功。maxNoteBytes 为必填项，按 UTF-8 字节限制备注文本；Web Host 组合将其设为 8192。该包通过 TypertRemoteService 与 @Remote 发布 Host messageFeedback.list、messageFeedback.put 和 messageFeedback.delete 一元 Remote 约定；下方生成的 Cordis API 是方法级权威。

插件释放会关闭操作接纳，并排空已进入各 Session 队列的工作。

显式启用后，session-log-deepseek 会在后续符合条件的 DeepSeek 请求中，把反馈作为普通 dsh_session_log 后缀的一部分传送。记录反馈不会触发 LLM 请求，也不会单独上传 dsh_feedback。对于非 DeepSeek 路由，OTel 后端可以将权威日志前缀释放至已记录的反馈。命令确认文本确认记录并标识 Session 与匿名用户，不报告遥测策略或投递结果。

Web 界面

@deepseek-ai/dsh-client-ui-message-feedback 是浏览器侧消费方。@deepseek-ai/dsh-api-remotes 挂载生成的 messageFeedback 贡献，因此该插件调用 ctx.remote.messageFeedback，不接触传输层。

控件是 conversation.chat.assistant-actions list slot 的 feedback 条目（order 10），该 slot 由 ui-conversation 声明，并渲染在已定稿助手消息的 IconActions 行内。AssistantMessageNode 携带来自 assistant/message 事件的可选 messageId。被中断冻结的部分输出没有该字段，渲染点在字段缺失时跳过该 slot。该操作栏每个 Turn 渲染一次，位于收尾的助手消息上：Host 接受每条 append-origin 步骤消息作为目标，但多步骤 Turn 中较早的步骤渲染的是工具行而非可评分正文，因此 UI 暴露的范围比 Host 约定允许的更窄。

每个 Session 一个 MessageFeedbackController，支撑该 Session 内所有消息的控件：一次 list 读取即填充整段对话，且延迟到首次 hover 或 focus 才发起，而非挂载时触发。每次变更把该 controller 最后观察到的版本作为 ifVersion 发送；version-conflict 响应携带权威条目，controller 据此对账而不重新拉取。变更按 Session 串行，排队操作与已提交版本比较。connection/reset 只刷新已读取过的 Session。

边界与限制

操作队列仅在进程内生效；cold 写入排他性依赖所选持久化提供方。
删除只移除当前条目，不会抹除 append-only 日志或已投递后缀中的早先备注。
请求若恰好落在 live detach 之后、persistence catalog 物化 header 之前的极短窗口，可能收到 session-not-found；调用方应在 retirement materialization 后重试。
cold 请求读取完整日志；服务没有条目数或聚合字节上限。maxNoteBytes 只限制每条备注。
Host 约定不记录已认证的 actor 或审计身份，因此假设调用方边界可信。
Web 控件只出现在对话视图。trajectory 与 waterfall 视图不渲染反馈条目，尽管它们的助手节点携带相同的 messageId。
Web 控制器不消费反馈日志事件，因此另一个标签页的评分要等到重连或下一次冲突响应才可见，不会立即出现。
备注编辑器不预先校验 maxNoteBytes；超长备注在保存时以 note-too-large 失败，而不是在输入过程中。

Cordis API

Generated from source by scripts/gen-cordis-catalog.ts (verified fresh by pnpm run verify-cordis-catalog in doc-sync; regenerate with pnpm run gen-cordis-catalog) — the language sides differ only in locale-specific paired document paths. Signature blocks use a ts cordis-catalog fence and keep the original source JSDoc; dispatch modes are defined in the primer, and the framework-inherited ctx API lives in cordis-api/inherited.md.

`ctx.messageFeedback` — `MessageFeedbackService`

Session-log service; cold operations never construct a Session or Agent.

`feedback/*` events

`feedback/committed` — parallel

Observe a durable cold feedback mutation without publishing a live Session. Observers run before write ownership is released and must not await another message-feedback operation for this Session. The payload is borrowed read-only; deep-clone it before transferring ownership (for example, to Session.fromRestore).
