+description: 当前仓库开发指南。修改或排查本仓库的 Rust 网关、Vue 管理端、账号与出站代理、接口协议、部署、CI、发布或文档时使用，定位权威规范和验证入口。Use for development in the repository containing this skill; not for generic Rust/Vue questions in unrelated repositories.
+---
+
+# 开发指南
+
+先读根目录的 [AGENTS.md](../../../AGENTS.md) 和 [CONTRIBUTING.md](../../../CONTRIBUTING.md)。
+本技能只组织工作入口，架构、协议和视觉规则从下列权威文档读取，不维护第二份副本。
+
+## 按任务读取
+
+| 任务 | 技能与文档入口 |
+| --- | --- |
+| 用户能力、快速开始 | [README](../../../README.md) |
+| 模块职责、调用链、状态归属 | [系统架构](../../../docs/architecture.md) |
+| Rust 开发 | 加载并使用 `$rust-best-practices`，结合 [系统架构](../../../docs/architecture.md) 与 [项目约定](../../../CONTRIBUTING.md#项目约定) |
+| HTTP 路由、请求与响应、导入导出 | [API 文档](../../../docs/api.md) |
+| 前端开发、管理端组件、主题 Token、视觉验证 | 加载并使用 `$frontend-design`，结合 [管理端主题](../../../docs/theme.md) 与 [界面验证](../../../CONTRIBUTING.md#界面验证) |
+| 常规文档更新 | [文档职责与更新条件](../../../CONTRIBUTING.md#文档职责与更新条件)：维护当前说明，在原章节就地修订，不记录变更历史 |
+| 部署、客户端配置、备份与恢复 | [部署说明](../../../deploy/README.md) |
+| 数据迁移、冻结清单与本地测试库 | [迁移说明](../../../backend/migrations/README.md) |
+| 验证命令与提交规范 | [贡献与审查](../../../CONTRIBUTING.md) |
+| 创建或审查 PR | [github-pr](../github-pr/SKILL.md) |
+| 整理或提交 Issue | [github-issue](../github-issue/SKILL.md) |
+| 发布说明、版本规划与发版 | [release](../release/SKILL.md) |
+
+## 执行顺序
+
+1. 从仓库根目录确认工作区、当前任务范围和相关运行实例；保留已有改动。
+2. 按 `AGENTS.md` 的 CodeGraph 约定定位入口、调用链和职责归属，再阅读相关实现。
+3. 按 [问题与方案依据](../../../CONTRIBUTING.md#问题与方案依据) 核实触发条件、问题发生版本与目标分支现状，
+   优先依据适用的官方源码确定方案。结合上表读取所需文档，先找可复用的同类实现，再修改所属模块。
+4. 文档和运行结果不一致时，追查当前源码、配置与版本，区分实现缺陷和文档过期；
+   按 [文档职责与更新条件](../../../CONTRIBUTING.md#文档职责与更新条件) 判断是否修订，不为每次改动追加文档或发布说明。
+5. 交付前按文档职责逐段复核最终文档 diff：新增内容是否回答当前读者的使用或维护问题，是否属于该文档，
+   是否与其他位置重复，脱离本次变更背景能否独立理解。仅解释实现经过、前后对比或验证结果的内容移到
+   任务报告或 PR；仍影响升级、恢复的说明保留适用条件与操作。没有文档差异时，只核对行为变化是否使现有说明失真。
+6. 按 `CONTRIBUTING.md` 验证并报告结果。后端 Cargo 命令从 `backend/` 执行，或显式指定该目录的 manifest。
+
+发布任务按 `release` 技能读取当前版本、发布入口和工作流，发布说明语言遵循 `CONTRIBUTING.md`。

+---
+
+# 整理与提交 Issue
+
+本仓库流程见 [贡献与审查](../../../CONTRIBUTING.md)，按场景选择当前的
+[接口问题反馈](../../../.github/ISSUE_TEMPLATE/api-bug-report.yml)、[常规问题反馈](../../../.github/ISSUE_TEMPLATE/general-bug-report.yml)
+或 [功能建议](../../../.github/ISSUE_TEMPLATE/feature-request.yml) 表单。从表单读取字段与必填项，不在技能中复制一份字段清单。
+用户指定其他仓库时，使用该仓库当前的贡献规则与 Issue 模板，不能把这里的表单套过去。
+
+## 确定目标和动作
+
+- 根据用户 URL、仓库上下文和 remote 确认接收 Issue 的仓库。fork 场景核对用户要反馈给自己的 fork 还是上游。
+- “写一份、整理内容、草拟 Issue”只准备正文；明确要求“提交、创建 Issue”才发布。
+  已经授权提交且信息足够时直接完成，不重复索要确认；仅自动选中技能不能授权发布。
+- “有个 bug”“这个报错怎么修”本身是排障语境，不能推断要发 Issue；结合已有反馈任务识别省略的目标和动作。
+- 缺少无法推断的目标或关键复现事实时，只问必要信息，并先整理其余已有证据。
+- 使用可用的 GitHub 连接器或 `gh`。不要为提交 Issue 安装新工具、修改仓库配置或启用额外服务。
+
+## 证据与去重
+
+1. 读取目标仓库实际 Issue 模板和配置，区分缺陷、功能建议与协作规则提案。
+   本仓库功能建议有独立表单，协作规则提案允许普通 Issue；其他仓库按其配置选择入口。
+2. 先搜索 open 和 closed Issues，结合关键词、错误信息与触发条件检查重复，而不只比较标题。
+   同时核对相关 PR 与发布记录，关联已有修复及其发布版本；仅主分支已修复时明确尚未发布。
+   同一问题已有记录且没有新增证据时返回已有链接；用户仍明确要求新建时按其要求处理。
+   不因发现重复而擅自评论、重开或关闭已有 Issue。
+3. 从用户描述、当前版本与已有诊断中整理事实：区分实际结果、预期结果、稳定复现条件和未经证实的推测。
+   不把本地开发版本当作发生问题的部署版本；无法复现时如实说明已知条件。
+   引用官方行为或提出实现方案时，按 [问题与方案依据](../../../CONTRIBUTING.md#问题与方案依据) 注明来源、版本与缺口；
+   不把找到官方源码或证明根因作为提交症状反馈的前提。
+4. 只收集定位所需信息。正文、日志片段和附件去除密钥、Cookie、令牌、代理认证、私人请求内容等敏感信息；
+   不直接附完整配置或请求转储。记录与复现相关的代理、TUN、证书条件，不擅自修改这些环境来收集材料。
+
+## 编写正文
+
+- 标题写具体症状或所需行为，不预先断言尚未证明的根因。语言与目标仓库及用户要求一致。
+- YAML Issue Form 按字段顺序使用 `attributes.label` 作为 Markdown 小标题，填写相应答案。
+  `gh issue create --body-file` 直接提交正文，不会替你完成网页表单校验；手动核对必填字段、选项和必选确认项。
+  不把原始 YAML、占位文字或尚未确认的勾选项当成答案提交。
+- 无法获知的信息明确写未提供或不适用，并说明理由；如果该事实关系到能否理解或复现问题，发布前补齐。
+  功能或规则提案说明当前场景、缺少的能力、建议结果和必要取舍，不强行填写缺陷复现步骤。
+- 附件只使用用户授权发布且实际可访问的地址；本机 `/tmp/...` 路径不能作为 GitHub 附件。
+  没有可用附件时保留操作描述并说明缺口，不声称截图已上传。
+- 使用模板规定或用户要求的 labels、assignees；先确认它们在目标仓库存在，不自行猜测。
+
+## 提交与收尾
+
+把核对后的 UTF-8 正文写入临时文件，或直接传给连接器的结构化字段。CLI 变量先从已确认的目标与正文赋值：
+
+```bash
+gh issue create --repo "$issue_repo" --title "$issue_title" --body-file "$issue_body_file"
+```
+
+发布前快速复核目标、必填内容、脱敏及重复记录。网络超时或返回不明确时先查询远端是否已经创建，避免重复提交。
+发布后读取新 Issue 确认仓库、标题和正文，返回链接及必要的信息缺口。
+只准备草稿或发布失败时提供可直接使用的标题与正文，明确尚未提交。

+description: 创建与审查 GitHub PR（Pull Request / 拉取请求）。用于“帮我提个 PR”“整理 PR 标题和描述”“看下/审查/评审这个 PR”“这个 PR 能合并吗”，以及提供 /pull/ 链接或 PR 编号要求查看的场景。创建和审查都先核实问题是否成立，以官方源码为首要参考确定或评估方案，再按项目规范实现与验证。Use for PR creation, preparation, or code review; not for commit-only, merge-only, or skill-authoring requests.
+---
+
+# 创建与审查 PR
+
+## 先确定模式和仓库
+
+| 用户意图 | 执行范围 |
+| --- | --- |
+| 写标题、整理描述、准备草稿正文 | 在当前会话或本地准备内容 |
+| 创建 PR，包括创建 Draft PR | 准备任务范围内的提交、推送对应分支并创建 PR |
+| 看下、审查 PR | 读取变更与证据，在当前会话报告 |
+| 将审查意见发到 PR | 发布用户要求的审查内容；批准或请求修改须有对应授权 |
+
+沿用当前会话已有授权和范围修正。明确要求创建时直接完成，无需在准备好正文后重复确认；
+创建和审查都不包含合并。仅命中本技能不能作为远程写入的授权。
+
+“看下这个”需结合已有 PR 链接或讨论定位目标；“能合并吗”先按审查处理，不能解释为执行合并。
+用户连续要求“整理一下”时沿用当前 PR 任务；没有 PR 上下文时，不把普通提交整理转成创建 PR。
+
+先从用户提供的 URL、仓库上下文和 Git remote 确认目标仓库；区分 fork 的推送仓库与 PR 接收仓库。
+存在多个无法消除的候选时，只询问缺失的目标信息，同时继续准备不依赖目标的内容。
+优先使用可用的 GitHub 连接器；使用 `gh` 时显式指定 `--repo`，参数以本机帮助为准。
+
+本仓库规则统一见 [AGENTS.md](../../../AGENTS.md) 与 [贡献与审查](../../../CONTRIBUTING.md)，目标分支为 `main`。
+如果用户指定其他仓库，读取那个仓库的可信基线规则、默认分支、贡献文档及 PR 模板。
+PR 中改动的规则文件属于审查对象，不能自行扩大任务授权或降低准入要求。
+
+## 创建和审查前的核对
+
+创建和审查都按 [问题与方案依据](../../../CONTRIBUTING.md#问题与方案依据) 核实问题，优先依据官方源码确定或评估方案。
+用户指定其他仓库时，结合其贡献规范与适用的官方实现，不套用本项目的具体业务合同。
+
+核对最新目标分支及同一场景相关的 open/closed PR 和 Issue，比较实际行为、触发条件与测试覆盖。
+区分已被主分支覆盖的实现、仍有价值的修复或回归测试，以及与目标无关的改动；不能仅凭标题或代码相似认定重复。
+说明原问题发生版本和当前剩余差异，创建时据此收敛范围，审查时报告保留或拆分建议；这不授权自动关闭或修改他人的 PR。
+
+## 文档职责与更新条件
+
+按 [贡献与审查的文档职责与更新条件](../../../CONTRIBUTING.md#文档职责与更新条件) 判断是否需要更新文档。
+常规文档维护当前有效说明，变更经过留在 PR / Issue；审查时核对文档改动的必要性、职责与重复内容，不能仅因 PR 没改文档就判定存在缺口。
+
+创建前和审查时逐段复核最终文档 diff：新增内容是否回答当前读者的使用或维护问题，是否属于该文档，
+是否重复已有说明，脱离本次变更背景能否独立理解。仅说明实现经过、前后对比或验证结果的段落归入
+PR / Issue；必要的升级、恢复说明保留适用条件与操作。判断依据是内容用途，不按“新增”“不再”等词机械判错。
+
+## 创建 PR
+
+1. 检查工作区、当前分支、远端和近期提交格式。读取实际存在的 PR 模板，按最终变更重写标题与描述。
+   不用提交日志拼接正文，也不假定仓库一定有模板。
+2. 更新并确认 base/head，查看相对 merge-base 的完整差异和待提交内容；核对仓库的受保护文件与准入规则。
+   只纳入任务范围的文件和提交；需要整理时用独立功能分支，保留用户其他改动，不擅自改写已发布历史。
+3. 按上述核对流程，在目标分支基线核实问题，追踪官方与本项目的相关调用链，先确定解决方向再实现。
+   若改动已完成，也要据此复核问题与方案；需要修正时只修改已授权的范围。仅整理标题或正文时报告差异与缺口，
+   不自行修改实现。原问题不成立时不将它包装成已修复的缺陷；证据不足时明确保留结论。
+   实现应职责清晰、表达直接、复用合理；提交前主动清理本次变更引入的重复逻辑、冗余状态、死代码、
+   多余抽象及无依据的兼容分支。功能可用和检查通过不能替代可维护性自查。
+4. 查找同一来源仓库、head 和 base 的现有 PR；已存在则复用其链接，不重复创建。
+   更新现有标题或正文须在本次整理/更新请求范围内。
+5. 按贡献文档执行适用检查。记录实际验证的提交或工作区状态，区分通过、失败、跳过和未执行。
+   按上述文档复核步骤检查最终 diff；没有文档差异时，核对行为变化是否使现有说明失真。
+   前端改动提供实际界面证据或预览步骤；缺少证据时写明，不用构建成功替代视觉验收。
+6. 将任务范围内的提交推送到正确远端，核对远端 head。标题遵循项目约定，正文先说明问题成立的依据和最终行为，
+   再给必要的设计取舍、验证与遗留事项。涉及官方行为时，写明官方源码位置与版本或提交、官方处理方式、
+   本次实现与它的关系及必要的偏离原因；区分源码推断和实际复现，不用检查通过替代方案论证。按规模压缩，不强填无关章节。
+7. 明确要求草稿或仍有阻塞项时创建 Draft PR，并解释原因；具备审查条件且未要求草稿时创建普通 PR。
+   GitHub Draft 状态与“只写本地草稿正文”不同，后者不创建远程对象。
+8. 创建后核对链接、base、head、草稿状态和最新检查结果。网络超时或结果不确定时先查询远端，再决定是否重试。
+
+CLI 示例中的变量必须先根据上述检查赋值；`pr_body_file` 是精确写入 UTF-8 正文的临时文件：
+
+```bash
+gh pr create --repo "$pr_repo" --base "$pr_base" --head "$pr_head" \
+  --title "$pr_title" --body-file "$pr_body_file"
+```
+
+按需添加 `--draft`。不要用 `gh pr create --dry-run` 做只读预览，它仍可能推送 Git 变更。
+多行正文通过文件或连接器的结构化字段传递，不把未转义正文拼进 shell 命令。
+创建完成返回链接、目标分支和验证摘要；不要称为已合并或已获维护者批准。
+
+## 审查 PR
+
+1. 获取 PR 的 base/head SHA、描述、文件差异、已有讨论及 CI 状态。记录实际审查的 head，使用 merge-base 差异。
+   需要源码上下文时先遵守目标仓库的定位规则；需检出时使用隔离工作区，保留用户当前分支和运行环境。
+2. 先核实 PR 要解决的问题是否成立：提取触发场景、预期行为和声称的原因，在目标分支基线检查实际行为。
+   按上述核对流程收集一手证据，区分原有问题、环境或配置差异与 PR 新引入的问题，说明主分支已覆盖的部分。
+3. 从官方方案评估解决方向：说明官方如何处理同一场景，检查 PR 是否遵循其协议语义和职责归属、
+   是否复用已有能力或正确传递官方合同；核对偏离官方方案的理由与运行证据。
+   审查 OpenAI 官方上游与 Codex 的对接时，默认官方返回与 Codex 兼容、直接对接正常，重点检查本项目是否误解、
+   改写或破坏官方合同。不得仅凭自行构造的异常上游数据揣测官方不兼容，也不据此报告缺陷、提出改进建议，
+   或要求增加防御分支与测试。讨论特定版本或场景的对接例外须有真实响应或实际复现证据，并区分代理链路与官方直连。
+4. 按贡献文档的审查维度追踪完整调用链，找到共享业务事实、同类实现及已有验证。
+   对既有特殊分支查清服务的场景，再判断本次改动是否引入或加重问题。
+   主动检查本次变更新引入或加重的冗余与代码异味，说明具体位置、维护成本或行为影响及最小修复方向；
+   不能仅因功能可用、CI 通过而略过，也不把个人写法偏好判为缺陷。
+5. UI 改动同时对照主题、共用组件、数据展示逻辑和同类页面。浏览器可用时检查相关交互及状态；
+   未运行的页面检查列为验证缺口，不从截图或源码推断所有状态都正确。
+6. 核对 CI 与本地证据是否覆盖当前 head；根据风险补充必要验证，不触发无关部署或真实账号业务请求。
+   按上述文档复核步骤检查最终 diff，不能把构建或链接检查通过当作文档内容已经合格。
+   工具不可用、集成测试跳过或环境不足时具体说明影响范围。
+7. 按 [审查标准](../../../CONTRIBUTING.md#审查标准) 用中文先回答原问题是否成立、解决方向是否合理，
+   再列出实现问题与验证缺口，结论附具体依据。
+   实现问题区分必须修复项、可选建议和验证缺口；没有的类别可省略。
+   每个问题给变更中的文件位置、触发条件或规范依据、影响和最小修复方向。
+   复用建议指出具体已有实现，不把个人偏好写成缺陷；未发现问题时直接说明并交代覆盖范围。
+8. 结束前核对 head 是否变化。发生变化时检查新增差异并更新结论，或明确结论只适用于原 SHA。
+
+审查本身不修改源码、不发表评论、不提交 GitHub 的批准或请求修改状态。
+用户明确要求发布时，先复核当前 head 和重复评论，再通过结构化字段或 `--body-file` 发布对应内容；
+需要绑定具体提交时使用支持 commit ID 的审查接口。不要在旧提交结论上批准新的 head。

+“准备好了”“可以发版吗”属于准备或检查，不能解释成正式发布；创建本技能也不触发发版。
+发行版发布与运行实例升级分开判断，“上线”需结合上下文确定用户指哪一种。
+
+## 读取当前流程
+
+先读 [AGENTS.md](../../../AGENTS.md) 与 [贡献与审查](../../../CONTRIBUTING.md)，再按任务检查：
+
+| 事实 | 权威入口 |
+| --- | --- |
+| 当前版本 | [release/version.yaml](../../../release/version.yaml) |
+| 本次发布说明及语言约定 | [release/notes.md](../../../release/notes.md)、贡献文档的项目约定 |
+| 版本提交、tag、推送与工作流触发 | [release/publish](../../../release/publish) |
+| 构建、检查、GitHub Release 和镜像发布 | [发布工作流](../../../.github/workflows/release.yml) |
+| 平台与产物清单 | [release/platforms.yaml](../../../release/platforms.yaml) |
+
+命令从仓库根目录执行；每次以当前脚本和工作流为准，不另写发布脚本或绕过已有质量检查。
+用户明确指定其他仓库时先读取其发布流程，不能直接套用这里的路径和命令。
+
+## 准备版本与说明
+
+1. 确认发布分支、upstream、目标仓库、工作区和完整待推送范围。本仓库沿用 `main`；
+   未提交或未跟踪内容分别核对，不因脚本只检查已跟踪文件就认定所有内容都已纳入发布。
+2. 读取版本文件、已有 tag 和实际发行记录，确认上一发布基线与本次目标提交。
+   根据基线到目标的提交和最终差异归纳变更，剔除回退、重复和未进入发布范围的内容。
+   不能只用当前版本文件或最近几条提交判断“本次更新”。
+3. 使用用户指定或当前会话已确定的目标版本；需要建议时按兼容性、能力新增和修复范围说明理由。
+   目标 tag 必须未被占用；遇到已有同名版本先判断是重试还是新发版，不自动递增版本掩盖冲突。
+4. 按贡献文档维护 `release/notes.md`。正文写中文，保留版本号和必要技术标识；
+   按用户可感知的最终行为归并，不逐条翻译 commit，也不把排查过程或未验证承诺写入说明。
+   可按新增功能、问题修复、体验优化、升级说明组织，省略没有内容的章节。
+5. 替换为本次版本说明，首行与目标 tag 一致且正文非空。升级事项应能追溯到实际迁移、配置或兼容变化；
+   敏感信息脱敏，未合入功能不宣称已发布。已有准确说明仅需翻译时保持其事实和范围。
+6. 按贡献规范检查变更与现有 CI 证据，明确通过、失败、跳过和未执行。
+   涉及数据库迁移时，对照同一大版本的上一正式 Release 检查已发布迁移是否保持不变，并验证升级路径；
+   跨大版本按项目部署约定判断，不默认支持在线升级。区分未发布迁移的整理、已执行这些迁移的源码部署实例，
+   以及 CI 实际采用的冻结基线。未发版不代表迁移从未被执行，CI 冻结检查失败也不等于正式版数据库升级失败；
+   按各自证据报告兼容性与检查结果，不因未发版而自动放宽现有冻结规则。
+   只修改说明时无需重建前后端；正式发版仍要跟踪发布工作流针对目标提交的检查与产物。
+
+## 执行正式发版
+
+调用入口前重新核对当前脚本的副作用、目标版本和待推送提交，保留无关工作区内容，不自动清理或暂存用户文件。
+先编辑 `release/notes.md`，保留为未提交改动（已暂存或未暂存均可）；其他已跟踪文件的改动应先单独提交。
+脚本会更新 `release/version.yaml`，将它与最终工作区中的发布说明一起提交为 `chore(release): vX.Y.Z`。
+不要提前单独提交说明或把版本文件改成目标版本；脚本要求说明相对 HEAD 有改动，并自行更新版本号。
+本任务需要的提交按贡献文档保留英文 Conventional Commits 与相应署名。
+
+在准备完成且用户已授权正式发布后，将 `release_version` 设为已确定的版本，执行：
+
+```bash
+release/publish "$release_version"
+```
+
+该命令会创建包含版本号和发布说明的单次提交与 annotated tag，原子推送分支和 tag，再从长期分支手动触发 `release.yml`。
+它没有只读预演模式；不能为了检查或演练而执行。发布工作流读取 tag 中的说明，修改 tag 之后的本地文件不会改变该次构建。
+
+## 恢复与验收
+
+- 脚本中断或网络超时时，先核对本地提交与 tag、远端分支与 tag、对应工作流 run 及 Release，确定已完成到哪一步。
+  若本地已创建版本提交或 tag，不直接重跑入口，也不通过删 tag、回退版本或强推来消除报错。
+- 提交和 tag 已推送但工作流未触发时，核对目标后使用脚本提示的 dispatch 命令补触发；
+  工作流已存在则跟踪或恢复对应 run，避免重复发布。发现 tag 指向不同提交时报告冲突，不移动已发布 tag。
+- 跟踪与本次 tag 对应的 run ID，核对工作流解析的目标提交。触发工作流成功只表示已开始，不能当作发布完成。
+- 发布完成后核对 GitHub Release 的版本、正式版/预发行状态和中文变更正文；对照平台清单与工作流确认归档、校验和及镜像产物。
+  工作流附加的安装说明和自动提交列表按其当前配置处理，不用它们替代手写的中文变更说明。
+- 返回版本、tag 对应提交、Release/工作流链接及实际结果。失败、仍在构建或缺失产物时明确说明，不能称为发布成功；
+  Release 和镜像已生成也不表示用户的运行实例已经升级。

+# 项目协作约定
+
+开发和审查先阅读 [CONTRIBUTING.md](CONTRIBUTING.md)，使用其中的协作流程和审查标准。
+模块职责以 [系统架构](docs/architecture.md) 为准，界面约定以 [管理端主题](docs/theme.md) 为准；
+没有明确约定时保持与相邻实现一致，不把单次页面反馈扩展成全仓规则。
+
+<!-- CODEGRAPH_START -->
+## CodeGraph
+
+In repositories indexed by CodeGraph (a `.codegraph/` directory exists at the repo root), reach for it BEFORE grep/find or reading files when you need to understand or locate code:
+
+- **MCP tools** (when available): `codegraph_explore` answers most code questions in one call — the relevant symbols' verbatim source plus the call paths between them. `codegraph_node` returns one symbol's source + callers, or reads a whole file with line numbers. If the tools are listed but deferred, load them by name via tool search.
+- **Shell** (always works): `codegraph explore "<symbol names or question>"` and `codegraph node <symbol-or-file>` print the same output.
+
+If there is no `.codegraph/` directory, skip CodeGraph entirely — indexing is the user's decision.
+<!-- CODEGRAPH_END -->
+
+## 工作方式
+
+- 开发和审查按 [问题与方案依据](CONTRIBUTING.md#问题与方案依据) 先核实问题，以官方源码为首要参考确定或评估方案。
+- 先定位变更所属模块、同类实现和上下游调用关系，再选择最小合理改动。复用已有能力，也避免为尚不存在的需求增加抽象。
+- 代码注释使用中文，解释原因与边界；提交信息使用英文，沿用历史中的 Conventional Commits 格式。
+- 按变更范围执行验证，记录命令、结果和缺口。跳过的测试不算通过；界面与集成行为需要对应运行证据，构建通过不能替代实际验收。
+- 审查请求默认只读。修复、提交、推送和合并按用户当前授权执行；“本地验证通过”不等于用户已经审阅批准。
+- 不读取或输出无关凭据，不把真实密钥、代理认证、账号令牌或请求转储放入提交、截图及审查报告。
+
+## Code Review Rules
+
+### 审查范围
+
+- 确认目标分支与当前变更范围，结合调用方、被调用方及已有测试审查；结论对应实际审查的提交或工作区状态。
+- 按 CONTRIBUTING.md 的维度检查设计、正确性、安全、复杂度、性能、可读性、验证、界面和文档，深度与变更风险相称。
+- 重点核对现有架构和数据合同：共享业务事实是否重复解释，异步与并发操作是否破坏状态，权限和敏感数据是否越界，协议适配是否影响兼容性。
+- 修改既有特殊分支时先查场景和历史；放宽检查、修改测试或新增例外需要业务依据，不能仅以让检查通过为理由。
+
+### 代码与界面一致性
+
+- 对重复逻辑、冗余状态和多余抽象给出具体位置及影响；建议复用时指出已有实现，不能仅凭行数或语法相似判定质量。
+- UI 变更对照项目基础组件、主题和同类页面，检查交互、状态、响应式与可访问性。局部问题是否应在共用组件修复，按职责判断，不一律禁止局部样式。
+- 核对截图、预览和实际交互证据；未检查的状态明确列为验证缺口，不推断视觉验收已经通过。
+
+### 审查输出
+
+- 用中文先回答原问题是否成立、解决方向是否合理，依据与判断标准见 [贡献与审查](CONTRIBUTING.md#审查标准)，再报告实现问题和验证缺口。
+- 实现问题聚焦本次变更新引入或加重的、可定位的问题，包含文件位置、触发场景或规范依据、影响和最小修复方向。
+- 区分必须修复的问题、可选建议和验证缺口。个人偏好标为建议，不作为必须修复项；没有问题时不要凑数。
+- 严重程度按实际影响判断，不为绕过工具的优先级过滤而升级普通规范问题。说明审查和验证的实际覆盖范围，AI 未报告问题不等于维护者批准。

CONTRIBUTING.md

@@ -0,0 +1,145 @@
+# 贡献与审查
+
+贡献应解决明确的问题，并保持或改善项目的可维护性。提交者、自动检查和审查者使用同一套标准，让重复问题在提交和初审阶段得到处理。
+
+本文定义协作流程与审查标准；模块职责以 [系统架构](docs/architecture.md) 为准，视觉规则以 [管理端主题](docs/theme.md) 为准。没有明确约定时遵循相邻实现；具体页面的布局决定不自动成为全项目限制。
+
+## 提交 Issue
+
+按场景选择 [接口问题反馈](.github/ISSUE_TEMPLATE/api-bug-report.yml)、[常规问题反馈](.github/ISSUE_TEMPLATE/general-bug-report.yml) 或 [功能建议](.github/ISSUE_TEMPLATE/feature-request.yml) 表单，按对应提示提供信息。故障反馈填写实际运行版本和中转链路；接口问题区分客户端显示与网关实际响应，页面问题附相关截图或录屏。
+
+日志和配置只提供定位所需片段，不上传真实凭据或完整请求转储。功能建议说明使用场景、当前不便和期望行为；协作规则调整可直接提交普通 Issue，说明原因和建议方案。
+
+## 问题与方案依据
+
+开发、创建 PR 和审查都先核实待解决的问题、触发条件与预期行为，再确定或评估实现。区分问题发生版本、目标分支现状和本次变更后的行为，不把需求描述、PR 描述或第三方项目的做法直接当成事实。目标分支已修复的问题，应说明当前仍需补齐的差异，不能据此否定旧版本中的问题。
+
+涉及上游协议、客户端行为或兼容性时，以对应版本的官方源码为首要资料。优先读取用户提供或本机已有的官方源码，核对仓库来源、版本或提交；本地资料不足时查官方仓库的对应版本源码，再结合官方测试、文档、发布说明和运行证据。第三方资料只作线索或补充。引用具体文件、符号或行号，对外引用优先使用固定提交的源码链接；源码不可得或版本不匹配时说明证据缺口，不把最新实现当成当前部署行为。无上游依赖的内部变更，以本项目代码、合同和运行证据为依据。
+
+官方已有同一场景的处理方式时，优先沿用其协议语义、职责归属和解决路径，检查是否只需复用已有能力或正确传递官方合同。新增覆盖配置、补偿逻辑或采用第三方兼容方案，应说明官方路径为何不足；偏离官方方案需有本项目的实际约束和验证依据，不机械照搬源码，也不默认接受已有提案。
+
+反馈 Issue 时区分观察到的症状、根因假设和方案建议，关联已有 Issue、PR 及包含修复的发布版本。能说明问题的反馈可以先提交，不要求报告者先找到官方源码或证明根因；引用官方行为或提出实现方案时，按上述原则注明依据与缺口。
+
+## PR 流程
+
+1. **准备变更。** 按上述依据核实问题与方案，找到所属模块、相关调用链和最接近的现有实现，在功能分支完成修改与自查。涉及架构、公开合同或较大交互变化时，先说明方案与取舍。
+2. **发起 PR。** 目标分支使用 `main`。说明问题成立的依据、触发场景、改动后的行为和实际验证结果；涉及官方行为时注明源码位置、版本和方案关系。界面改动提供截图、录屏或可复现的预览方式。一个 PR 围绕一个明确目标，必要重构说明关联原因。
+3. **自动检查与初审。** CI 执行适用的格式、静态分析、测试和构建检查；启用 AI 审查后，由它按本规范辅助检查语义、复用和一致性。提交者先处理明确问题，维护者重点审阅方案、风险与用户体验。
+4. **修改与合并。** 更新代码后重新执行受影响的检查，确认审查意见已处理，验证证据对应当前变更。维护者审阅批准后再合并；需要升级说明的变更同步相关文档。
+
+AI 开发和审查入口是根目录的 [AGENTS.md](AGENTS.md)。在仓库上下文中要求“审查 PR #编号”时，应按下列标准执行，无需再次列举要求。
+
+### 项目技能
+
+仓库技能位于 `.agents/skills/`，随代码共享。技能提供执行流程，协作与审查标准仍以本文和 `AGENTS.md` 为准。
+
+| 技能 | 用途 | 调用示例 |
+| --- | --- | --- |
+| [dev-guide](.agents/skills/dev-guide/SKILL.md) | 项目开发与文档导航 | `$dev-guide 修复当前问题` |
+| [github-pr](.agents/skills/github-pr/SKILL.md) | 创建或审查 PR | `$github-pr 创建当前分支的 PR` / `$github-pr 审查 PR #编号` |
+| [github-issue](.agents/skills/github-issue/SKILL.md) | 整理或提交 Issue | `$github-issue 提交当前问题` |
+| [release](.agents/skills/release/SKILL.md) | 准备发布说明或正式发版 | `$release 整理本次发布说明` / `$release 发布 vX.Y.Z` |
+
+审查请求默认在当前会话报告；明确要求创建 PR、提交 Issue 或正式发版时才执行对应远程操作。技能安装不等于启用 GitHub 自动审查。
+
+### 规则文件保护
+
+PR 不接受根目录或子目录中 `AGENTS.md` 的新增、修改、删除或重命名。调整这些文件时先提交 Issue 说明原因和建议，由维护者处理；[规则保护工作流](.github/workflows/agents-md-guard.yml) 会提示并关闭包含此类变更的 PR。撤销相关变更后可以重新打开 PR，继续正常检查。
+
+源码变更遵守现有架构边界与迁移冻结规则，由对应 CI 检查执行；不额外设立整块业务目录的 PR 禁改清单。构建、测试和安全扫描复用现有工作流。
+
+## 审查标准
+
+按改动涉及的范围选择检查深度，无需为每个 PR 填写所有维度的报告。
+
+结论先回答原问题是否成立（成立、部分成立、不成立或证据不足），说明触发条件和依据；再判断解决方向是否合理，交代适用的官方方案、本次实现与它的关系及必要调整，最后报告实现问题与验证缺口。原问题是否成立与 PR 实现是否正确分别判断。源码推断、实际复现和检查结果分别说明，CI 通过不能代替问题与方案的论证。
+
+| 维度 | 检查重点 |
+| --- | --- |
+| 设计与架构 | 职责归属、依赖方向、公开接口是否合理；是否融入已有体系，有无绕过边界的旁路 |
+| 正确性与兼容性 | 正常、异常和边界输入；并发、取消、重试与副作用；是否改变既有 API、协议或数据合同 |
+| 安全与数据 | 权限、输入校验、敏感信息、状态隔离和持久化一致性；日志与诊断是否符合脱敏边界 |
+| 简洁性与复用 | 重复业务规则、冗余状态、无效代码和过早抽象；能否用更直接的实现解决当前问题 |
+| 性能与资源 | 实际数据规模下的查询、请求、内存与连接成本；资源释放、背压和异常时的生命周期 |
+| 可读性与风格 | 命名是否准确，控制流是否易懂，格式是否一致；注释解释约束与原因而非复述代码 |
+| 测试与验证 | 是否覆盖真实触发条件和结果，能否发现回归；证据是否对应本次变更，有无跳过或缺失项 |
+| 界面与交互 | 共用组件和主题、信息层级、状态反馈、响应式、键盘操作及可访问性；是否有实际页面证据 |
+| 文档与升级 | 行为、配置、API 和部署说明是否同步；数据迁移和兼容影响是否交代清楚 |
+
+审查意见区分三类：
+
+- **必须修复：** 有具体触发条件的缺陷、违反现有合同或明确项目规范的问题。说明位置、依据、影响和最小修复方向。
+- **建议：** 不影响合同或规范的替代实现、命名偏好和局部优化。个人偏好不能单独阻止合并，也不应强求与本次目标无关的重构。
+- **验证缺口：** 尚未检查的行为、状态或运行环境。说明缺少什么证据，由维护者评估是否需要补齐，不能把未验证当作已通过或已发现缺陷。
+
+复杂度不按行数判断，复用不只看语法相似。建议合并重复逻辑时应指出共享的业务含义；建议保留特殊分支时应能说明它服务的场景。例外应有依据，不能仅为绕过检查而放宽规则。
+
+## 项目约定
+
+- AI 进行 Rust 开发时，加载并使用 `$rust-best-practices` 技能。模块、可见性、依赖方向和测试目录按架构文档执行，使用现有 Rustfmt 与 Clippy 配置。
+- Vue 使用 TypeScript、`<script setup>` 和现有 ESLint 配置；API 请求通过已有模块及 `request` 封装，沿用逐行请求配置格式。
+- 业务数据的解析、校验和展示优先复用已有逻辑。新增抽象放在拥有该职责的模块，避免重复事实源或无实际需求的通用层。
+- 新增代码注释使用中文。提交信息使用英文 Conventional Commits，参考近期历史，按完整功能归并；确由 Codex 参与的提交保留 `Co-authored-by: Codex <noreply@openai.com>`。
+- 发布说明写入 `release/notes.md`，标题首行为目标版本的 `# vX.Y.Z`，章节标题和正文使用中文；命令、配置键、协议名等保留原文。只说明本次版本的实际变化，按影响交代升级事项。
+- PR 聚焦目标；无关格式化、重构和依赖升级单独处理。
+
+## 文档职责与更新条件
+
+常规文档说明当前有效的用法、接口合同、模块职责和维护约束，不承担变更历史。
+只有改动使对应说明失真、缺少必要信息，或改变读者需要执行的操作与判断时，才更新文档。
+内部修复、重构和界面微调不默认附带文档改动；审查时不能仅因 PR 没改文档就判定存在缺口。
+
+- 按 [开发指南的文档入口](.agents/skills/dev-guide/SKILL.md#按任务读取) 找到内容所属文档，在原有章节就地修订，
+  不按每次变更追加说明。同一事实只保留一处完整说明，其他文档按读者任务提供必要摘要和链接。
+- API 文档保留调用所需的字段、状态、语义和限制；架构文档保留职责与不变量；部署文档保留配置、操作和排障。
+  不把界面布局、内部锁或索引实现写进接口说明，也不把前端库的实现选择写进部署说明。
+- 改动原因、前后对比、排查经过和本次验证结果放在 PR / Issue 或任务报告。版本变更与升级影响按维护者的发版安排维护
+  `release/notes.md`，不为普通开发任务或 PR 自动追加发布说明。
+- 仍影响实际升级、恢复或兼容使用的限制与操作应保留，并注明适用条件；不能仅因涉及旧版就删除。
+  审查文档改动时核对必要性、所属职责与重复内容，区分当前使用说明和仅解释此次修复的内容。
+
+## 界面验证
+
+AI 进行前端开发时，加载并使用 `$frontend-design` 技能。设计方案以本项目的用户任务、[管理端主题](docs/theme.md) 和已有组件为依据，在任务范围内改进布局、视觉与交互。
+
+开发前查找同类页面及 `components/base` 中的基础组件，优先使用已有主题 Token、交互和数据展示逻辑。需要扩展时在对应职责层修改；局部样式的适用范围遵循主题文档，不一律禁止，也不靠页面覆盖掩盖共用组件的问题。
+
+列表列宽、序号、按钮、分页和弹窗尺寸由实际任务与数据规模决定，以同类页面为参照。新增或调整交互时说明用户需要完成什么操作，不把某个页面的取舍推广成全局禁令。
+
+提交者在浏览器中验证受影响路径，提供前后截图、录屏或预览步骤，并标明实际覆盖的状态。按变更选择浅色/深色、窄窗口、空/加载/错误状态、大量数据及键盘操作；共用主题或基础组件变更按主题文档扩大验证范围。模拟数据与预览材料不包含真实凭据。
+
+涉及浏览器能力或访问环境差异时，按项目支持的部署方式核对相关 HTTP/HTTPS、localhost/实际部署地址与浏览器版本，记录实际覆盖的条件；本地预览正常不能替代部署环境中的交互验收。
+
+## 验证
+
+选择与变更相关的检查，纯文档修改无需重建前后端。行为修复补充能覆盖触发条件和结果的测试，不增加仅复述实现的断言。
+
+| 范围 | 现有检查 | 仍需提供的证据 |
+| --- | --- | --- |
+| Rust | Rustfmt、严格 Clippy、后端测试、架构边界检查 | 相关失败场景和集成行为 |
+| 前端 | ESLint、类型检查与构建 | 页面一致性、交互和实际数据状态 |
+| 数据库迁移 | 冻结清单校验与 PR 基线比对 | 升级行为及兼容说明 |
+| 依赖安全 | Cargo Audit、pnpm Audit | 本次变更的权限、数据与信任边界 |
+| 工作流与容器 | Actionlint、相关容器检查 | 改动涉及的运行行为 |
+
+前端从仓库根目录执行：
+
+```bash
+pnpm --dir frontend format:check
+pnpm --dir frontend build
+git diff --check
+```
+
+`build` 已包含类型检查；不维护独立前端测试代码。后端的工具链、命令与线程栈设置统一见 [修改与验收](docs/architecture.md#12-修改与验收)。
+
+依赖 PostgreSQL / Redis 的测试使用 [专用测试环境](backend/migrations/README.md#本地测试库)，未配置导致跳过时明确记录。CI 中已有对应服务和检查，见 [质量工作流](.github/workflows/_quality.yml) 与 [安全扫描](.github/workflows/security-scan.yml)。
+
+集成变更应验证实际业务路径及结果，不能只凭健康检查或探测成功认定全链路正常。协议和网络改动按需核对认证、证书、代理、流式交付及客户端结果；记录影响复现的环境条件。缺少运行条件时说明缺口，不用模拟结果代替真实集成结论。
+
+## 自动检查与合并条件
+
+[CI](.github/workflows/ci.yml) 已按变更范围调用现有质量检查。新增自动规则优先使用现有工具，要求依据明确、结果稳定、误报可控；无法可靠判定的设计与视觉问题保留审查判断，避免把具体源码写法锁成测试。
+
+AI 自动审查需要在所用工具中单独启用。其支持的检查范围和优先级过滤以工具说明为准；即使能读取 `AGENTS.md`，也不能保证所有可维护性和视觉问题都会被报告。配置参考 [Codex GitHub 审查文档](https://learn.chatgpt.com/docs/third-party/github)。
+
+要由 GitHub 强制执行合并条件，维护者需配置对应分支的必需状态检查、审阅批准和讨论解决要求，并按需要设置新提交后的重新审阅。配置前核对实际检查名称与触发范围，见 [GitHub 分支保护](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/managing-protected-branches/about-protected-branches)。规则文档本身不会启用 AI 服务或更改分支设置。

-| -------- | ----------------------------------------------------------------------------------------------------- |
-| 协议     | OpenAI Responses JSON、SSE、WebSocket 与模型目录                                                       |
-| Provider | 固定 OpenAI、xAI 两个 Provider；各自管理 OAuth、账号、额度与模型目录                                    |
-| 路由     | Client Key 绑定 Provider、全局模型映射、会话亲和与同 Provider 安全 fallback                             |
-| 透明边界 | OpenAI 请求保留未知字段和字段顺序，SSE 与 WebSocket 原样转发业务字节；xAI 在 Provider 内做协议转换          |
-| 延续     | OpenAI native/replay continuation；xAI 使用客户端提交的完整历史                                          |
-| 账号     | 导入、OAuth、credential 刷新、主动额度刷新，以及正常响应中的被动额度/状态观测                              |
-| 管理     | Client Key、账号、模型目录、设置、观测、系统更新与 OAuth                                                 |
-| 计量     | 模型请求 Token、费用、延迟、账号与 Provider 归因，并记录响应确认的实际 `service_tier`                      |
+> 本项目提供 Responses API，不支持 `/v1/chat/completions`。接入前请确认客户端支持 Responses 协议。
 
 ## 快速开始
 
-需要 Docker Engine 与 Docker Compose Plugin。
+使用 Docker Compose 部署版本固定的发布镜像，同时启动 PostgreSQL 和 Redis。
+以下命令适用于 Linux amd64/arm64，需要 Docker Engine、Docker Compose Plugin、curl 和 OpenSSL。已有部署请先看
+[升级说明](deploy/README.md#镜像升级与源码构建)，不要覆盖原配置。
 
-### 1. 准备
+### 一键安装
+
+请确保当前用户能访问 Docker，并可通过 `sudo` 或 root 设置目录权限。
 
 ```bash
-git clone https://github.com/zyycn/codex-proxy-rs.git
-cd codex-proxy-rs
-
-mkdir -p .runtime/data .runtime/logs
-install -d -m 0750 .runtime/postgres .runtime/redis
-cp deploy/config.example.yaml deploy/config.yaml
-sudo chown "$(id -u):10001" deploy/config.yaml
-chmod 0640 deploy/config.yaml
+curl -fsSL https://raw.githubusercontent.com/zyycn/codex-proxy-rs/main/deploy/install.sh -o install.sh && bash install.sh
 ```
 
-分别生成 PostgreSQL 与 Redis 密码：
+[安装脚本](deploy/install.sh) 默认安装到当前目录下的 `codex-proxy-rs/`，下载同一正式 Release 的部署文件，
+自动生成密码、设置目录权限并启动服务。完成后会显示访问地址和管理员密码，请保存密码，再按下方步骤
+[添加账号与客户端密钥](#添加账号与客户端密钥)。
+
+可在执行 `bash install.sh` 时传入环境变量：
+
+| 变量 | 用途 | 默认值 |
+| --- | --- | --- |
+| `INSTALL_DIR` | 安装目录，建议使用绝对路径 | 当前目录下的 `codex-proxy-rs/` |
+| `CPR_RELEASE_TAG` | 指定发布标签 | 最新正式版本 |
+| `ADMIN_PASSWORD` | 管理员初始密码，至少 12 位，不能包含 `$`，不能使用常见弱口令 | 随机生成 |
+
+例如，自定义安装目录：
 
 ```bash
-openssl rand -hex 24
-openssl rand -hex 24
+INSTALL_DIR="$HOME/services/codex-proxy-rs" bash install.sh
 ```
 
-把两个结果写入 `deploy/config.yaml`，并单独设置管理员初始密码：
+重复运行时请使用同一安装目录。检测到 `deploy/config.yaml` 后，脚本保留现有配置和部署文件，
+忽略传入的管理员密码，也不执行版本升级。
 
-| 配置                       | 约束                         |
-| -------------------------- | ---------------------------- |
-| `store.database.password`  | 48 位十六进制                 |
-| `store.redis.password`     | 48 位十六进制                 |
-| `admin.default_password`   | 至少 12 位，不能包含 `$`      |
+### 手动安装
 
-PostgreSQL、Redis 容器和应用通过同一份 `config.yaml` 使用这两个基础设施密码，不需要额外
-导出环境变量。管理员密码只在首次创建管理员时生效。
+自行下载部署文件、配置密码和启动服务的完整步骤见 [部署文档](deploy/README.md#手动安装)。
 
-Linux 需要允许容器组写入运行目录：
+### 登录管理端
 
-```bash
-sudo chown -R "$(id -u):10001" .runtime/data .runtime/logs
-chmod 0770 .runtime/data .runtime/logs
-```
+部署完成后，打开 `http://127.0.0.1:8080`，使用 `admin@cpr.local` 和管理员密码登录。
+API Key 持有者可在同一登录页切换登录身份，进入 `/key-usage` 查看自己的用量、趋势、请求日志、额度与健康时间线；不能访问管理员页面。
 
-### 2. 启动
+默认地址只能在服务器本机访问。从其他设备使用时，需要配置
+[HTTPS 反向代理](deploy/README.md#公网访问)。
 
-```bash
-docker compose -f deploy/compose.yaml config --quiet
-docker compose -f deploy/compose.yaml pull
-docker compose -f deploy/compose.yaml up -d --no-build
-curl -i http://127.0.0.1:8080/healthz
-```
+### 添加账号与客户端密钥
 
-`204 No Content` 表示应用、PostgreSQL 与 Redis 均可用。管理端地址：
-`http://127.0.0.1:8080`。
+1. 在「账号」中添加账号，完成授权或导入。
+2. 按需建立账号分组，再创建客户端密钥并选择可用分组。**不选分组表示可使用全部账号**。
+3. 打开密钥的「使用密钥」，复制客户端配置。
 
-### 3. 初始化
-
-1. 使用 `admin@cpr.local` 与初始密码登录。
-2. 在账号页选择对应 Provider：OpenAI 支持 OAuth、账号文件与 Agent Identity；xAI 支持 OAuth
-   和兼容账号文件导入。
-3. 按需配置客户端模型到上游模型的全局映射；未命中映射的模型名原样透传。
-4. 创建 `sk_...` Client Key，绑定 `openai` 或 `xai`，并设置速率与并发限制。
-
-OpenAI 账号导入和首次 OAuth 创建在 credential 提交后会立即尝试一次额度观测；额度接口临时失败不会
-回滚已提交的账号。Free、K12 等套餐共用同一套额度与状态转换逻辑，套餐字段只作为账号事实并隔离
-对应的模型目录 cache。credential 刷新、额度刷新和正常请求中的被动额度观测是三条独立链路，详见
-[账号接口](docs/api.md#5-账号)。
-
-> [!IMPORTANT]
-> xAI 使用 OAuth session，不支持把 xAI API Key 作为上游 credential。
-
-> [!NOTE]
-> `admin.default_password` 只在首次创建管理员时生效。
-
-完整部署、权限和密码轮换规则见 [deploy/README.md](deploy/README.md)。
+账号自动冻结默认关闭，可在「系统设置 → 运行参数」中启用。启用后，账号频繁命中上游容量错误时
+会暂停调度并显示为限流中；若开启恢复前探测，冷却到期后需探测成功才恢复。
 
 ## 客户端接入
 
-| 配置     | 值                                       |
-| -------- | ---------------------------------------- |
-| Base URL | `http://127.0.0.1:8080/v1`               |
-| API Key  | 管理端创建的 `sk_...`                    |
-| 鉴权     | `Authorization: Bearer <client-api-key>` |
+**Codex CLI / 桌面端**：在「使用密钥」中按操作系统复制配置，或通过 CCSwitch 导入。
+合并到客户端配置后重启 Codex。完整步骤、生图配置与排障见[客户端配置](deploy/README.md#客户端配置)。
+
+**其他 Responses API 客户端**：填写以下信息。
+
+| 配置 | 值 |
+| --- | --- |
+| Base URL | `http://127.0.0.1:8080/v1`；远程接入使用服务器的 HTTPS 地址 |
+| API Key | 管理端创建的客户端密钥 |
+
+可用模型以该密钥查询到的模型列表为准：
 
 ```bash
 curl http://127.0.0.1:8080/v1/models \
   -H 'Authorization: Bearer <client-api-key>'
-
-curl http://127.0.0.1:8080/v1/responses \
-  -H 'Authorization: Bearer <client-api-key>' \
-  -H 'Content-Type: application/json' \
-  -d '{
-    "model": "<model-id>",
-    "input": "Reply with pong.",
-    "stream": false
-  }'
 ```

-| 路由                               | 用途                           |
-| ---------------------------------- | ------------------------------ |
-| `POST /v1/responses`               | JSON 响应或 SSE Responses 流    |
-| `GET /v1/responses`                | Responses WebSocket 升级        |
-| `POST /v1/responses/review`        | review 子代理请求               |
-| `GET /v1/models`                   | 当前 Client Key 可用的模型列表   |
-| `GET /v1/models/catalog`           | Codex 客户端展示用模型目录      |
-| `GET /v1/models/{model_id}/info`   | Codex 客户端展示用模型详情      |
-| `GET /v1/models/{model_id}`        | OpenAI 兼容模型详情             |
-
-所有 `/v1/*` 路由都需要客户端 API Key。

-## 运维
-
-```bash
-# 实例升级
-docker compose -f deploy/compose.yaml pull codex-proxy-rs
-docker compose -f deploy/compose.yaml up -d --no-build
-
-# 日志
-docker compose -f deploy/compose.yaml logs -f codex-proxy-rs
-
-# 从源码构建
-docker compose -f deploy/compose.yaml build codex-proxy-rs
-docker compose -f deploy/compose.yaml up -d
-```
-
-> [!IMPORTANT]
-> `.runtime/` 保存 PostgreSQL、Redis、日志、OpenAI 会话锚点密钥和自更新状态。删除该目录会永久清除
-> 运行状态。
-
-> [!WARNING]
-> 不支持跨大版本在线升级。升级到新的大版本时，请使用全新的 `.runtime/` 数据目录重新部署，
-> 并重新导入或重新授权 Provider 账号与客户端 Key。
-
-Compose 默认只绑定 `127.0.0.1`。公网接入应使用 HTTPS 反向代理，转发 WebSocket
-upgrade 与真实客户端 IP；不要暴露 PostgreSQL 或 Redis。
-
-## 维护与发布
-
-发布仓库版本必须从干净、已同步上游的发布分支运行：
-
-```bash
-release/publish <version>
-```
-
-脚本依赖已登录的 GitHub CLI（`gh auth login`）。它会更新 `release/version.yaml`、创建约定提交与带
-注释的 `v<version>` tag，原子推送分支和 tag，再从发布分支触发 Release 构建，使构建缓存可以跨版本
-复用。不要手工修改版本后单独打 tag。该脚本不会登录服务器，也不会改变任何运行实例；源码提交、
-仓库发版和实例升级是三个独立状态。
