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，由 @deepseek-ai/dsh-command-feedback 连同两种反馈共用的 FeedbackCategory 分类表一起拥有。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、可选分类、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（重复已存评分、备注与分类的 put）。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；`command-feedback` 以同样方式发布面向 live Session 的 Session 级备注 `sessionFeedback.record`。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。

默认情况下，[`session-log-deepseek`](../../packages/session/session-log-deepseek/README.zh.md) 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；组合可用 `enabled: false` 禁用它。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](../../packages/session/session-telemetry-otel/README.zh.md)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`](../../packages/client/ui-message-feedback) 是浏览器侧消费方。`@deepseek-ai/dsh-api-remotes` 挂载生成的 `messageFeedback` 与 `sessionFeedback` 贡献，因此该插件调用 `ctx.remote.messageFeedback` 与 `ctx.remote.sessionFeedback`，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。注入的 `retract` 操作会在该队列内重新检查已提交评分，并在并发变更后变为无操作，因此陈旧 UI 无法绕过弹窗记录裸评分。`connection/reset` 只刷新已读取过的 Session。

任一未记录的评分都会打开该 Session 的反馈弹窗，即 `conversation.input.overlay` 的 `feedback-dialog` 条目：共用的 Modal 卡片，里面是七个分类标签和一个详情框。提交会 put 所选评分，带上所选分类与去除首尾空白的描述，两者也可都不带；成功会关闭弹窗并显示确认 toast，失败则保留弹窗与草稿并显示警告 toast。不带文本的 `/feedback`（`ui-commands` 以 `action` 路由的一个装饰）为 Session 打开同一个弹窗，随后通过 `sessionFeedback.record` 记录；`/feedback <text>` 仍走宿主命令路径。再次点击已记录的评分会直接撤回，不打开弹窗。

## 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。
- 弹窗不预先校验 `maxNoteBytes`；针对消息的超长描述在提交时以 `note-too-large` 失败，而不是在输入过程中。Session 级备注没有大小上限，`/feedback` 命令从来也没有。
- `sessionFeedback.record` 只服务 live Session，否则回答 `session-not-found`；弹窗打开期间 Session 退役时，弹窗会报告该失败。

## 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](../cordis-primer.zh.md#dispatch-modes), and the framework-inherited `ctx` API lives in [cordis-api/inherited.md](../cordis-api/inherited.md).

### `ctx.messageFeedback` — `MessageFeedbackService`

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

```ts cordis-catalog
/**

 * @param request - Session to inspect.
 * @returns immutable items or a definite persistence miss.
 */
@Remote('list') list(request: MessageFeedbackListRequest): Promise<MessageFeedbackListResult>

/**
 * Create or replace feedback after checking its current version.
 * Matching no-ops retain the version and append no event.
 * @param request - Target, desired value, and observed item version.
 * @returns the durable item or an explicit business failure.
 */
@Remote('put') put(request: MessageFeedbackPutRequest): Promise<MessageFeedbackPutResult>

/**
 * Delete one item after checking its version; absence succeeds without an event.
 * @param request - Session, message, and observed item version.

`ctx.sessionFeedback` — `SessionFeedbackService`

Host Remote through which a product surface records a Session-level remark.

``ts cordis-catalog /** * Record one remark on a live Session. * @param request - target Session plus the optional text and category. * @returns the recorded postcondition, orsession-not-found` when no live * Session carries the id. */ @Remote('record') record(request: SessionFeedbackRecordRequest): Promise

### `feedback/*` events

<a id="feedbackcommitted--parallel"></a>

#### `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).
