概要

人格定义页 v1(beta,默认关)——设计稿 reports/persona-page-design.md(六项推荐拍板)的落地,车道 feat/persona-page @ 41043b2。

改动

  • settings.js:user_settings 加 persona 键(PERSONA_FIELDS 白名单挑拣、坏 JSON 容错回空对象),getPersona/setPersona;FEATURE_FLAG_BOOLEANS 追加 personaEnabled
  • api.js / api-standalone.js:GET+PUT /persona 双面路由(internal 写面 requireAuth;坏 JSON 体不清空库值——jsonOk 守卫)
  • config.js:personaEnabled: z.boolean().default(false)(双闸门的 config 半边,不进 LIGHT_MODE_OFF,同 actionPipelineEnabled 定性);api.test.js effective 计数锁同步 +1
  • inject.js:renderUserSettings 双闸门扩展,人格段前置(人格→画像→规则,rules 恒最硬);任一闸关时输出逐字节等于历史版本(老用户零变化)
  • lib/client.js:人格卡(名字/性格/回复要求 + 卡内开关即改即存)+ 「Agent 眼中的你」只读卡 + group.enhance 开关 + 中英 i18n 各 14 键

测试

  • 新增:persona-settings(6) / persona-api(5) / persona-flag(3) / persona-inject(6) + client 回归锁(1)
  • 全量 npm test:1891 pass / 0 fail / 1 skipped(skip = runtime-adopt 符号链接断言,Windows 环境性)
  • check-sync 62 文件平价 ✓

分层纪律

v1 只动 L-身份层(user_settings 的 persona 键);记忆层与画像/规则层代码零改动。

实现报告:车道内 dsh-mneme/reports/persona-v1-implementation.md

Summary by CodeRabbit

  • 新功能

    • 设置页新增人格卡,可配置姓名、性格和回复风格,并单独启用或关闭。
    • 新增人格注入总开关;总开关与人格卡开关均启用时,人格信息才会加入提示内容。
    • 设置页新增只读注入文本预览。
    • 新增受认证保护的人格设置接口,支持读取和保存人格信息。
  • 文档

    • 新增人格定义页 v1 实现报告。

设计稿 reports/persona-page-design.md(六项推荐拍板)的落地:
- settings.js:user_settings 加 persona 键(PERSONA_FIELDS 白名单挑拣、
  坏 JSON 容错回空对象),FEATURE_FLAG_BOOLEANS 追加 personaEnabled
- api.js / api-standalone.js:GET+PUT /persona 双面路由(internal 写面

- config.js:personaEnabled 默认 false(双闸门的 config 半边,不进
  LIGHT_MODE_OFF),api.test.js 计数锁同步 +1
- inject.js:renderUserSettings 双闸门扩展,人格段前置(人格→画像→规则,
  rules 恒最硬);任一闸关时输出逐字节等于历史版本
- lib/client.js:人格卡(三字段+卡内开关即改即存)+ 画像只读卡 +

📝 Walkthrough

新增 persona 设置的存储、API 和设置界面。渲染器仅在顶层 personaEnabled 与 persona 的 enabled 同时启用时,才将非空人格字段加入 user-settings。

Changes: 人格定义页与注入

层 / 文件 摘要
Persona 设置与功能开关
dsh-mneme/lib/config.js, dsh-mneme/src/config.js, dsh-mneme/lib/settings.js, dsh-mneme/src/settings.js, dsh-mneme/test/api.test.js, dsh-mneme/test/persona-flag.test.js, dsh-mneme/test/persona-settings.test.js
新增 persona 字段白名单、容错读取和过滤写入;新增默认关闭的 personaEnabled 配置及功能标志。测试覆盖配置默认值、开关读写和 persona 字段处理。
Persona API 读写
dsh-mneme/lib/api-standalone.js, dsh-mneme/src/api-standalone.js, dsh-mneme/lib/api.js, dsh-mneme/src/api.js, dsh-mneme/test/persona-api.test.js, dsh-mneme/reports/persona-v1-implementation.md
新增宿主 API 与 standalone API 的 persona 读取和写入路由。测试覆盖认证、有效写入及错误 JSON;实现报告记录两类 API 的错误 JSON 处理差异。
人格内容注入
dsh-mneme/lib/inject.js, dsh-mneme/src/inject.js, dsh-mneme/lib/lang.js, dsh-mneme/src/lang.js, dsh-mneme/test/persona-inject.test.js
双重开关启用后,渲染器按名称、性格和回复风格输出非空人格字段,并将人格段置于画像和规则之前。新增中英文模板及门控、顺序、空字段和转义测试。
人格设置界面
dsh-mneme/lib/client.js, dsh-mneme/test/client.test.js
设置界面加载并保存 persona,提供独立的卡内开关、人格字段表单和只读注入文本预览。新增双语文案和界面回归测试。

Merge Risk: 🔵 Low · up to 41043

The persona editor can show "saved" when the server rejected the write, for example when the browser holds no API token. The feature is off by default, so impact is narrow; fix the success check before or shortly after merge.

Security architecture risk: 🔵 Low · up to 41043

The feature defaults off and retains existing write-access controls, limiting exposure. When enabled, persona text can influence the assistant’s instructions. A failed attempt to turn it off can nevertheless appear successful while the saved persona remains active.

Retained concerns

  • Low · security · inferred: The new live persona opt-out can appear completed without changing persisted state. The checkbox immediately becomes unchecked, while savePersona treats any resolved HTTP response as success. If an enabled persona receives a 401 rejection during disable, storage remains enabled but the UI announces success; with the runtime global gate still enabled, subsequent renders continue including that persona. This weakens the feature’s opt-out contract, although exposure remains bounded to the existing settings instance and instruction channel.
Security review details

Security Blast Radius

  • inferred — The supported write-to-instruction scope is the settings database and all contexts using its injector, not a request-specific user identity. An authorized settings writer—or a reachable caller where the host token is unset—can supply persona text. Cross-tenant reach and additional downstream tool or credential authority were not established.

Security Findings and Attack Paths

  • observed — The retained injection finding concerns persona text entering system instructions without semantic isolation or explicit field-length limits. The path is persona write, persisted JSON, both rendering gates, STR formatting, then user-settings context. Strong counterevidence limits the architectural delta: the same writers could already supply unrestricted profile/rules text to the same context at the PR base. The underlying condition predates this PR; no higher instruction channel or broader write authority was demonstrated.

Trust Boundaries and Controls

  • observed — Controls include default-off global opt-in, a strict per-persona enabled check, field whitelisting, render-time string checks, and default brace escaping. They constrain activation and template processing, but do not make settings text lower-trust than profile/rules or enforce the stated “rules hardest” precedence.

Resilience and Maintainability Implications

  • inferred — The live opt-out needs a trustworthy persistence acknowledgement because the other gate changes only after restart. Unlike the existing feature-switch save path, persona saving neither checks HTTP success nor reconciles the checkbox with returned state. Rejection can therefore leave displayed consent inconsistent with effective rendering.

Hardening Proposals

  • proposed — Make persona opt-out completion depend on confirmed persisted state, preserve an explicit failure state, and order or version overlapping saves so an older request cannot silently undo a later disable. Keep restart-scoped global configuration distinct from the live persona control.

18-25: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

测试没有验证 lightMode 排除行为。

第 23 行 cfg.lightMode === true ? cfg : cfg 两个分支相同,void light 丢弃结果。该测试只验证白名单包含 personaEnabled,注释声称的"不在 lightMode 排除名单"没有被断言。请删除这段无效代码,或改为断言 applyLightModePreset 不会关闭 personaEnabled。

第 27-36 行的测试名称称 effective snapshot 包含 personaEnabled,但实际只调用 settings,没有经过 createApi。该路径已由 api.test.js 覆盖,建议改名或删除。

人格段启用后,块头仍为"用户画像与规则"。模型可能把人格行误读为用户画像。非阻塞,可酌情调整文案。

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

savePersona 静默忽略 HTTP 错误。

apiFetch 在 401/500 时不会抛错。代码仍显示"人格已保存"并播报。设置 apiToken 后,若浏览器未存令牌,PUT 返回 401,用户会误以为已保存。卡内开关还会立即写入,且本地状态已更新。

请检查 res.ok,失败时不显示成功提示。

建议修复
-          await apiFetch("/api/dsh-mneme/persona", {
+          const res = await apiFetch("/api/dsh-mneme/persona", {
             method: "PUT",
             headers: { "Content-Type": "application/json" },
             body: JSON.stringify({ persona: next })
           });
+          if (!res.ok) return;

对人格字段执行单行化并限制长度。 persona.name、persona.personality 和 persona.replyStyle 会直接进入系统提示词。字段中的换行可伪造后续提示词行,超长内容也会扩大提示词注入面。请在两个 inject.js 文件中对这三个字段使用统一的单行化和长度限制函数,再传给 STR.persona*Line。

合并冲突时 git 把两边的加法串自动拼了,但只体现了一个 +1——实际上
两边各加了一键(actionRunEnabled 与 personaEnabled),effective 应为 99。
顺手把那条 26 项加法串收成一个字面量:这串每合并一次就要重算一遍,
拼得越长越没人验算,换成 99 配一行注释反而可查。
