+# 2026-10-29 个人分支上传说明
+
+用户明确要求将本次本地修改上传到 baskbuddy/zhangshun 的 qingsongpin-AIDevelop 分支。
+
+本批提交当前 AI-003 项目经历、自我评价优化实现、提示词、测试及接口契约，并同步 AI-003、AI-004 六份方案和交付文档。包含已有本地合并提交 ff52692，将整合基线 c6ccab5 带入个人分支。本次仅上传当前版本，未修改生产代码或测试，不实施尚待审批的 v1.2 修复。
+
+上传前验证：OpenAPI 校验通过，217 paths / 265 operations；git diff --check 通过。本次未重新执行 Maven。历史 AI-003 首轮验证为 19 项，16 通过、2 错误、1 跳过；v1.2 测试修复、修复后回归及完整构建仍待完成，详见 AI-003 后端整合说明。真实模型、Redis、MySQL、前端联调及生产验收未完成。AI-004 为文档交付，不代表页面已上线。
+
+随附文档中“未提交、未推送”等为原编写时状态；本批上传状态以 Git 提交记录及远端分支为准，测试和审批状态保持原有结论。本次未向其他分支推送，未创建或合并 PR，未部署。

+# AI-003 项目经历与自我评价 AI 优化前端对接方案
+
+日期：2026-10-27。状态：本地实现候选，首轮验证完成；两处测试设施修复待v1.2审批，尚未推送、未部署、未开展前端联调或真实模型质量评测。
+
+## 接口与鉴权
+
+基础地址使用团队联调后端，路径带 `/api/v1`；全部请求用现有 `Authorization: Bearer <access-token>`，仅 STUDENT 本人。不要传userId。同步JSON，无分页或流式输出。
+
+| 方法 | 地址 | 用途 |
+| --- | --- | --- |
+| GET | `/api/v1/profile/me/project-experience-optimization/notice` | 项目经历当次告知 |
+| POST | `/api/v1/profile/me/project-experience-optimization` | 项目描述优化 |
+| GET | `/api/v1/profile/me/self-evaluation-optimization/notice` | 自评当次告知 |
+| POST | `/api/v1/profile/me/self-evaluation-optimization` | 自评优化 |
+
+先GET对应notice；展示message、provider、purpose、dataFields和版本；enabled=false时提示暂不可用。只有用户明确同意本次调用才POST；不要默认勾选或复用历史同意。提交 `externalProcessingConsent` 为原生JSON布尔true；字符串true、false、null、缺失均400。`consentNoticeVersion` 使用本场景当前返回值；版本过期重新获取告知并让用户确认。
+
+## 请求字段
+
+项目：projectName可选≤150；role可选≤120；description必填非空≤5000；targetPosition可选≤120。当前告知版本 `project-experience-external-processing-v1`。
+自评：description必填非空≤5000；targetPosition可选≤120。当前告知版本 `self-evaluation-external-processing-v1`。
+不自动提取或提交整份简历。项目名称使用公开名称或脱敏代称，不提交手机号、邮箱、证件、密码、密钥、商业秘密或其他人资料。长度以服务端Java字符串校验为准。
+
+合成项目示例：
+```json
+{"projectName":"课程商城","role":"参与开发","description":"使用Java实现订单查询接口，协助编写测试，尚未上线。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"project-experience-external-processing-v1"}
+```
+
+合成自评示例：
+```json
+{"description":"学习Java和SQL，在课程项目中编写接口测试，遇到问题查阅文档并记录排查过程。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"self-evaluation-external-processing-v1"}
+```
+
+## 响应与采用
+
+沿用ApiResponse：code、message、data、requestId、timestamp。data字段：
+
+| 字段 | 含义 |
+| --- | --- |
+| status | OPTIMIZED或NEED_MORE_INFO |
+| optimizedDescription | 建议正文≤5000；信息不足时null或省略，不回填 |
+| suggestions | 提示数组 |
+| followUpQuestions | 补充问题数组 |
+| promptVersion | 场景提示词版本，与告知版本不同 |
+| simulated | true表示模拟，仅返回原文；false不证明本次已经外呼 |
+
+真实提示词版本为project-experience-deepseek-v1、自评self-evaluation-deepseek-v1；模拟分别project-experience-v1、self-evaluation-v1。界面明确模拟标签，不能宣称stub完成AI润色。
+
+调用时保留原文，禁止重复点击；返回后展示原文与建议，由用户主动采用或取消。期间用户若已编辑原文或切换条目，不自动把旧响应覆盖当前字段。NEED_MORE_INFO展示问题，不将空正文当成优化结果。
+采用项目建议只回填原条目description；采用自评只回填selfEvaluation。沿用原保存接口、条目id、其他字段及最近revision；409重新读取并提示用户处理冲突，不自动覆盖。AI接口不保存、不改评分或可见范围。
+
+## 失败、超时与重试
+
+400检查参数/同意版本/敏感内容；401按现有会话流程处理；403角色不符；404用户不存在；429共享配额或并发已满，响应Retry-After:60，不自动重试；502输出无效；503关闭/配置/Redis/上游不可用；504模型超时。模型默认超时20秒、可配置1–60秒，前端超时应与联调配置协调并留有网络余量。
+所有失败保留原文，不自动保存或静默再次外呼；用户手动重试时重新确认本次处理同意。提示用安全错误文案与requestId，不收集原文或Token到普通前端日志。
+
+## 联调及待确认
+
+两项默认off；后端可分别开stub供契约联调。真实模式需负责人配置real-enabled及供应商凭据，且正式授权、供应商留存/训练规则核实完成后再决定开放。三项优化共享工作经历Redis配额，切换入口也会消耗相同预算。
+已在本地H2及stub下验证完整JWT权限链、建议返回与在线简历revision/content不变；不代表真实MySQL、模型质量或前端流程已验收。前端按钮、实际保存调用与revision处理由前端负责人联调确认。

+# AI-003 项目经历与自我评价 AI 优化后端整合说明
+
+日期：2026-10-27。状态：本地实现候选，未提交AI-003、未推送、未部署；v1.2测试修复待批准。本文件须在最终验证和推送后更新。
+
+## 基线与边界
+
+实际仓库 `D:/巴适/轻松聘-ai智能助手`；个人分支qingsongpin-AIDevelop；origin为 `https://gitea.baskbuddy.com/baskbuddy/zhangshun.git`。用户个人分支已备份至backup/qingsongpin-AIDevelop-20261027；整合分支c6ccab5合入个人分支的本地合并提交ff52692。没有reset或强推，没有修改整合分支远端内容。后续合并请求目标仍须负责人确认，本批不创建/合并PR。
+
+新增项目经历、自评各一组notice GET与优化POST；只提供建议、不持久化、不修改前端、评分、排名或可见范围。接口契约见同编号前端对接方案及仓库docs/resume-api.md、docs/openapi-rc.json。
+
+## 代码结构与文件
+
+生产新增均在 `mydreamjob-server/src/main/java/com/mydreamjob/resume/optimization/`：
+
+- ResumeSection、ResumeSectionInput：固定场景及最小数据；不暴露原文toString。
+- ResumeSectionInputGuard：同意/字段边界、安全拒绝、缺乏事实的本地处理。
+- ResumeSectionModelClient、StubResumeSectionModelClient、DeepSeekResumeSectionModelClient、ResumeSectionModelRouter：独立模型契约、模拟、固定官方地址HTTP适配及分别开关。
+- ResumeSectionConsentNotice、ResumeSectionOptimizationService、ResumeSectionOptimizationController、ResumeSectionOptimizationExceptionHandler：告知、STUDENT鉴权、共享配额、四路由及安全错误。
+- ResumeSectionOptimizationOpenApiConfiguration：运行时布尔同意枚举。
+- dto/ProjectExperienceOptimizationRequest、dto/SelfEvaluationOptimizationRequest、dto/ResumeSectionOptimizationResponse：两类请求与统一建议响应。
+
+资源新增在src/main/resources/ai/：project-experience-v1.txt、project-experience-deepseek-v1.txt、self-evaluation-v1.txt、self-evaluation-deepseek-v1.txt。
+测试新增八份：ResumeSectionInputGuardTest、ResumeSectionModelRouterTest、DeepSeekResumeSectionModelClientTest、ResumeSectionOptimizationServiceTest、ResumeSectionOptimizationControllerTest、ResumeSectionOptimizationSecurityIntegrationTest、ResumeSectionPromptRegressionTest、ResumeSectionCallLimiterRedisIntegrationTest。
+仓库文档修改：docs/openapi-rc.json、docs/verify_openapi.py、docs/resume-api.md。旧工作经历生产代码、认证、保存服务、数据库迁移均未改动。
+
+## 配置、运行与集成
+
+无新增依赖、数据库表或迁移。沿用Java17及现有SpringBoot工程启动方式，服务前缀/api/v1。新路由默认关闭；分别配置：
+```yaml
+ai:
+  project-experience:
+    mode: off
+    real-enabled: false
+  self-evaluation:
+    mode: off
+    real-enabled: false
+```
+stub无需模型/Redis，不执行润色，只返回原文或补充问题。deepseek须本场景real-enabled=true，沿用DEEPSEEK_API_KEY/MODEL/TIMEOUT_SECONDS和固定DeepSeek地址，启动时校验配置；不限制profile。无真实外呼重试、禁止重定向、响应流式字节上限65536。
+复用WorkExperienceCallLimiter和原ai.work-experience.limits.*；三项功能共用Redis额度/租约，原key名称保留。默认每用户3次/分钟、20次/日、全局200次/日、并发4、每用户并发1、租约75秒。Redis故障503失败关闭；额度接受即消耗，租约释放不退额。信息不足本地路径不占模型额度。
+
+整合步骤：核对个人分支提交及差异；合入负责人指定目标分支；保持新模式off；构建并运行定向测试、OpenAPI校验；stub环境按前端对接说明验证四接口及原保存流程；最后由负责人单独决定真实模型和生产放行。不要将提示词约束或离线测试当作无幻觉保证。无真实用户资料外发测试。
+
+## 已执行验证及未完成项
+
+合并基线：工作经历113项，0失败/错误、2跳过，排除需要Docker的旧Redis测试；OpenAPI213/261通过。
+AI-003首轮：19项，16通过、2错误、1跳过。两处错误均为Mockito重设桩触发旧Answer/异常；补充修复方案v1.2待批准。完整JWT链、原简历不写入以及运行时/静态217/265操作集合与新请求契约一致验证通过；OpenAPI脚本217/265通过。git diff --check当前变更通过。
+新Redis测试仅在显式提供AI_TEST_REDIS_HOST（可配AI_TEST_REDIS_PORT）时连接团队专用实例，不启动/停止Docker、不清库；目前未提供因此跳过。不要对共享生产Redis执行测试。
+尚未完成：修复后定向回归、全量构建、最终提交/推送、真实Redis验证、真实模型质量/延迟/费用评测、供应商留存/训练与正式告知核实、前端联调及生产验收。H2验证不能替代真实MySQL验收。
+
+潜在冲突：原工作经历安全测试全仓数量写死213/261，应跟随新增四路由改217/265，已列v1.2审批；静态OpenAPI和resume-api.md是多人编辑点，合并时保留其他业务路由。模型settings、限流类为既有复用依赖，后续如负责人修改应回归三项能力。
+回滚先把两项mode=off；必要时撤销AI-003精确增量提交，保留其他人后续修改；无数据库回滚，不reset或强推。

+# AI-003 项目经历与自我评价 AI 优化实现方案
+
+版本：v1.2（补充测试修复方案）；日期：2026-10-27（Asia/Shanghai）；状态：v1.1已批准并实施；v1.2待批准，尚未应用本节测试修复。
+
+## v1.2 本次待批准的精确变更
+
+v1.1首轮实现已完成并验证：新模块19项测试，16通过、2错误、1因未提供专用Redis实例跳过；新完整JWT链与静态/运行时契约验证通过；OpenAPI脚本通过（217 paths/265 operations）。本版本仅修复测试设施，不改生产代码、接口、数据库、配置或依赖。
+
+1. `D:/巴适/轻松聘-ai智能助手/mydreamjob-server/src/test/java/com/mydreamjob/resume/optimization/ResumeSectionOptimizationServiceTest.java`：将已有Answer桩上的后续 `when(...).thenThrow(...)` 换成 `doThrow(...).when(...)`。Mockito重设时先调用旧Answer且参数为null，导致测试自身NPE；用do语法避免执行旧桩。
+2. `D:/巴适/轻松聘-ai智能助手/mydreamjob-server/src/test/java/com/mydreamjob/resume/optimization/ResumeSectionOptimizationControllerTest.java`：同理，后续重设已有异常桩统一使用 `doThrow/doReturn`，防止旧异常在测试准备阶段抛出；保留所有HTTP错误映射断言。
+3. `D:/巴适/轻松聘-ai智能助手/mydreamjob-server/src/test/java/com/mydreamjob/resume/optimization/WorkExperienceOptimizationSecurityIntegrationTest.java`：仅将全仓硬编码数量213/261改为217/265，并将该测试方法名称更新为反映保留旧操作及新增AI操作。保留操作集合逐项对比、原工作经历鉴权和契约断言。该文件是v1.1预计文件范围之外的必要测试兼容调整，因此单列审批。
+
+实施方式：只改以上三份测试；重跑新模块和工作经历定向测试（不启动Docker，旧Docker Redis测试排除；新Redis真库测试无显式实例时跳过），随后执行完整Maven构建验证并如实记录环境依赖失败；再次运行OpenAPI校验及差异检查，完成交付说明与工作记录后提交并推送个人分支。无新增接口或契约变化。回滚仅撤销这三份测试的本次差异，不重置分支、不强推。真实模型评测、前端联调和生产验收仍待单独开展。
+
+以下v1.1正文继续适用，其生产实现范围未扩大。
+
+## 1. 目标、基线与范围
+
+在负责人整合后的后端基础上，新增项目经历、自我评价两项 AI 文本优化能力。只提供建议，不自动保存；用户采用后回填原编辑字段，沿用既有在线简历保存、revision 冲突处理。不得编造事实，不修改评分、排名、推荐、隐私范围或前端代码。
+
+实际 Git 仓库为 D:/巴适/轻松聘-ai智能助手，origin 为 https://gitea.baskbuddy.com/baskbuddy/zhangshun.git。D:/巴适/轻松聘/zhangshun 为历史非 Git 副本，不作为本次编码基线。2026-10-27 已执行 git fetch origin；当前本地/远端跟踪分支 qingsongpin-AIDevelop 位于 4784fd5，工作区干净；截图所示整合分支 origin/fix/mysql57-module-migrations-20261009 位于 c6ccab5。两分支从 8c94291 分叉：qingsongpin 独有1个提交，fix分支独有26个提交，不能用普通快进更新；c6ccab5 也不是 4784fd5 的后代。fetch 仅更新远端引用，没有改工作分支。
+
+按用户指定，工作分支与最终上传目标为 qingsongpin-AIDevelop。获批后先把当前远端整合分支合并到 qingsongpin-AIDevelop，保留双方历史，不重写或强推。该同步会将整合分支已有的26个提交纳入个人分支，且两个分支的工作经历 AI 文件有重叠，可能产生冲突；先在本地处理并验证，不静默丢弃任一方行为。如果冲突涉及方案范围外的业务语义或无法安全判断，暂停实现并报告具体冲突，不扩大范围。成功同步后在该个人分支完成 AI-003，运行测试、核对差异并生成交付文档；用户明确要求完成后上传到自己的分支，因此实现及验证完成后提交并推送 origin/qingsongpin-AIDevelop，不推送其他分支、不合并 PR、不触发部署。实施前再次检查分支状态及适用 AGENTS.md；若远端出现新提交，先核对批准基线范围，不擅自扩项。
+
+已核查远端 WorkExperienceOptimizationService/Controller/ModelRouter、ConsentNotice、CallLimiter、DeepSeek 客户端、OnlineResumeContent/Controller、phase1-scope-and-acceptance.md。c6ccab5 已有严格同意反序列化、告知版本、真实调用显式开关、Redis 原子限流与并发租约；旧本地文档中的“仅 dev 真实模式”已不适用。代码存在不等于本轮验收通过。
+
+现有 OnlineResumeContent.Project 包含 name≤150、role≤120、description≤5000；selfEvaluation≤5000；目标职位≤120。已有 GET/PUT /api/v1/profile/me/online-resume 和项目条目接口。前端实际按钮、采用与保存调用尚未核验，由对接文档标明联调确认，不作为后端实现前置条件。项目名称可能包含商业秘密，须用公开名称或脱敏代称。
+
+## 2. 新增接口契约
+
+全部接口使用 Authorization: Bearer <access-token>，仅当前 STUDENT 本人。服务端执行角色校验，不接收 userId，不读取其他人的资料。统一 ApiResponse 包装（code/message/data/requestId/timestamp），同步 JSON，无分页或 SSE。
+
+| 方法 | 路径 | 功能 |
+| --- | --- | --- |
+| GET | /api/v1/profile/me/project-experience-optimization/notice | 项目经历处理告知；关闭模式亦可查看 |
+| POST | /api/v1/profile/me/project-experience-optimization | 优化一段项目描述 |
+| GET | /api/v1/profile/me/self-evaluation-optimization/notice | 自我评价处理告知；关闭模式亦可查看 |
+| POST | /api/v1/profile/me/self-evaluation-optimization | 优化已有自我评价 |
+
+项目请求：projectName 可选≤150，role 可选≤120，description 必填非空≤5000，targetPosition 可选≤120；externalProcessingConsent 必填且必须为 JSON 布尔 true；consentNoticeVersion 必须等于告知当前版本 project-experience-external-processing-v1。
+
+自我评价请求：description 必填非空≤5000，targetPosition 可选≤120；同意字段规则相同，版本 self-evaluation-external-processing-v1。本轮仅基于用户提交的原文润色，不自动扫描整份简历或生成无事实的自我评价；缺乏具体依据时返回补充问题。
+
+项目请求示例（合成）：
+```json
+{"projectName":"练习商城","role":"后端开发","description":"参与课程商城项目，使用Java实现订单查询接口，编写接口测试并修复分页问题。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"project-experience-external-processing-v1"}
+```
+自我评价请求示例（合成）：
+```json
+{"description":"学习过Java和SQL，在课程商城项目中实现订单查询接口并编写测试，遇到问题会查阅文档并记录解决过程。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"self-evaluation-external-processing-v1"}
+```
+成功示例：
+```json
+{"code":200,"message":"ok","data":{"status":"OPTIMIZED","optimizedDescription":"在课程商城项目中负责订单查询接口开发，使用 Java 实现查询逻辑，编写接口测试并修复分页问题。","suggestions":["如有可验证的测试结果，可补充说明。"],"followUpQuestions":[],"promptVersion":"project-experience-deepseek-v1","simulated":false},"requestId":"example-request","timestamp":"2026-10-27T02:00:00Z"}
+```
+自我评价响应字段完全相同，promptVersion 为 self-evaluation-deepseek-v1。信息不足时 status=NEED_MORE_INFO，optimizedDescription=null 或按现有序列化规则省略，followUpQuestions 非空，不将空经历润色成虚假成果。stub 提示词版本分别为 project-experience-v1、self-evaluation-v1，simulated=true；simulated=false 仅表示真实模式，不证明每次已外呼。
+
+notice 响应 data 沿用 version/title/provider/purpose/dataFields/message/mode/enabled/developmentOnly。分别列出项目的 projectName/role/description/targetPosition、自我评价的 description/targetPosition；说明本次同意、第三方传输、可拒绝且不影响手动保存、人工复核、不自动保存，以及供应商留存/训练规则尚待核实，不承诺零留存。
+
+异常：400 参数/非法同意/告知过期/敏感输入；401 未登录；403 角色不符；404 用户不存在；429 配额或并发已满，Retry-After=60；502 模型输出无效；503 功能关闭、Redis不可用或上游不可用；504 超时；500 未预期错误。业务错误码沿用既有注册表，不新增业务枚举；安全错误不回显原文、供应商正文和异常堆栈。前端超时、失败时保留原文，429 不自动重试；其他模型失败由用户手动重试并再次确认本次调用。
+
+## 3. 实现方式与 AI 边界
+
+在 com.mydreamjob.resume.optimization 内新增独立的 ResumeSection* 公共执行层服务于两项新能力，保留现有工作经历公开契约及实现。使用明确的 section 枚举选择字段、提示词、告知版本和配置，禁止客户端任意指定模型地址或提示词路径。独立项目和自评 DTO 映射为内部输入；不把项目角色伪装为工作职位来复用旧提示词。
+
+复用 ConsentBooleanDeserializer、DeepSeekWorkExperienceSettings、WorkExperienceModelException 和现有 WorkExperienceCallLimiter。两项新接口与工作经历共享现有 Redis 配额池和并发门禁（现有名称保留），防止切换入口绕过全局预算；该变化意味着新调用会消耗工作经历相同配额，须在交付文档明确。沿用默认每用户3次/分钟、20次/日、全局200次/日、并发4、每用户同时1次、75秒租约。Redis失败关闭，额度不退还，不自动外呼重试。
+
+新输入校验独立处理全部可传输字段，继承现有敏感数据/密钥拒绝与提示词注入防护模式；无事实原文先在本地返回 NEED_MORE_INFO，同意和安全检查仍先执行。新 DeepSeek 适配器复用设置，沿用固定官方地址、禁止重定向、连接5秒、请求超时1–60秒（默认20）、响应流式字节上限65536、严格 JSON 字段/类型/长度校验及诊断日志禁用策略。建议正文≤5000；建议和问题列表按现有客户端边界限制。
+
+项目提示词围绕背景、本人职责、实际行动和有依据的结果组织；不补造团队规模、技术栈、指标或贡献归属。自评围绕原文中的技能、实践与工作方法改写，不推断人格、敏感属性或“精通”等无依据能力。输入作为不可信数据，与系统指令分离；模型无工具和业务写入权限。两类提示词分别版本管理，输出仅为建议；确定性校验不能证明所有语义事实，须保留人工复核并做合成样本评测。
+
+不保存输入、输出或完整提示词，不输出到普通日志、DTO toString、错误信息。外呼仅传本节最小字段，不传姓名、联系方式、完整简历、账号标识或会话。Redis仅保存现有计数与租约，不保存文本。供应商留存及正式授权仍须负责人核实，默认关闭，测试只用合成资料。
+
+## 4. 精确预计文件范围
+
+以下相对 D:/巴适/轻松聘-ai智能助手；无删除。
+
+新增生产 Java（均在 mydreamjob-server/src/main/java/com/mydreamjob/resume/optimization/）：
+- ResumeSection.java：两类能力及提示词/告知元数据。
+- ResumeSectionInput.java：内部最小输入与内容脱敏 toString。
+- ResumeSectionInputGuard.java：安全输入与空事实识别。
+- ResumeSectionModelClient.java：内部建议契约。
+- DeepSeekResumeSectionModelClient.java：真实 HTTP 与严格输出验证。
+- StubResumeSectionModelClient.java：明确模拟的合成联调行为。
+- ResumeSectionModelRouter.java：分别选择模式与真实开关。
+- ResumeSectionOptimizationService.java：鉴权、同意、安全检查、限流及结果组装。
+- ResumeSectionConsentNotice.java：各场景版本化告知。
+- ResumeSectionOptimizationController.java：四个新增路由。
+- ResumeSectionOptimizationExceptionHandler.java：仅新控制器的安全错误映射。
+- ResumeSectionOptimizationOpenApiConfiguration.java：必要的运行时契约补充，保持静态契约一致。
+- dto/ProjectExperienceOptimizationRequest.java、dto/SelfEvaluationOptimizationRequest.java、dto/ResumeSectionOptimizationResponse.java：独立请求与统一响应。
+
+新增资源：mydreamjob-server/src/main/resources/ai/ 下 project-experience-v1.txt、project-experience-deepseek-v1.txt、self-evaluation-v1.txt、self-evaluation-deepseek-v1.txt。
+
+新增测试：mydreamjob-server/src/test/java/com/mydreamjob/resume/optimization/ 下 ResumeSectionInputGuardTest.java、ResumeSectionModelRouterTest.java、DeepSeekResumeSectionModelClientTest.java、ResumeSectionOptimizationServiceTest.java、ResumeSectionOptimizationControllerTest.java、ResumeSectionOptimizationSecurityIntegrationTest.java、ResumeSectionPromptRegressionTest.java、ResumeSectionCallLimiterRedisIntegrationTest.java。
+
+修改：docs/openapi-rc.json（四路由及 schema）；docs/verify_openapi.py（本模块断言及实际数量）；docs/resume-api.md（新能力及保存边界）。不修改旧工作经历代码、在线简历保存代码、认证或数据库迁移。若发现复用必须修改旧生产类或需增加文件/扩大范围，更新方案重新审批。
+
+工作区文档：D:/巴适/轻松聘/docs/AI-003-项目经历与自我评价AI优化-实现方案.md；完成后新增同编号前端对接方案、后端整合说明；追加根工作记录.txt。新对外交付文档不放 mydreamjob-server/docs/。
+
+## 5. 数据库、依赖、配置及外部服务
+
+无数据库迁移、无新增依赖、无新供应商或独立服务。沿用项目 Java/Spring/Jackson/Redis 及已有 DeepSeek 设置；具体模型名称只是当前代码配置事实，本轮未核验供应商能力或价格，非推荐结论。
+
+新增 ai.project-experience.mode 与 ai.self-evaluation.mode，取 off/stub/deepseek，默认 off；各有 real-enabled，默认 false。deepseek 需对应 real-enabled=true 且原有 DEEPSEEK_API_KEY/DEEPSEEK_MODEL/DEEPSEEK_TIMEOUT_SECONDS 有效，不限制运行 profile。不修改现有 ai.work-experience.* 语义；共享配额由其现有 limits 配置管理并明确文档说明。本批不改环境文件或默认开启真实模型，不实际外呼第三方。
+
+## 6. 验证、验收与交付
+
+先执行整合基线的适用工作经历定向测试，记录已有失败与新增失败。实现后执行 Maven 定向测试覆盖 *ResumeSection*Test、*WorkExperience*Test，真实模型测试保持关闭；再执行 mvn clean verify（外部环境不足如实记录）。运行 python ./docs/verify_openapi.py，核对静态与运行时新增 schema、必填项、鉴权与错误；不沿用历史 API 数量。执行 git diff --check 与精确文件差异检查。
+
+必要测试：两场景正常/不足事实/空白/长度边界；true 与字符串/数字/null/false 的严格区别；缺失/过期/跨场景告知版本；未登录/其他角色；off 与显式真实开关；Redis故障关闭、配额/并发及租约；超时/非200/重定向/畸形JSON/超大响应/敏感输出；注入与密钥输入；DTO和错误无内容泄漏；工作经历契约回归。Redis真实集成使用团队可用测试实例，未经授权不启动或停止Docker；不可用标记未完成。无数据库变更，不声称开展真实 MySQL 验收。
+
+合成评测集通过测试内样本版本管理，至少覆盖各场景的事实充分、仅空泛形容、无经历、恶意指令、敏感数据、诱导编造指标；验收要求受控失败路径不外呼、不写库、不泄漏，输出结构合法，回归样本不得新增无依据事实。真实模型质量/延迟/费用评测及前端联调本批未授权执行，交付中标记待验；不宣称达到生产验收。
+
+兼容性：四路由增量新增、默认关闭；不改变现有保存和评分。采用后由前端保持原条目字段、id、revision；项目回填 description，自评回填 selfEvaluation，409 重新读取并由用户处理冲突，不自动覆盖。
+
+回滚：先将两项 mode=off，必要时撤销本批精确文件与文档差异，保留用户后续修改；无数据库回滚。不执行 reset --hard、force push 或覆盖旧开发分支。测试后如需再改代码，按 AGENTS.md 另报修复方案审批。
+
+## 7. 当前状态与待办
+
+已完成：远端fetch、分支拓扑与保存契约只读核对、用户批准v1.1方案；已在 qingsongpin-AIDevelop 创建备份分支并将 origin/fix/mysql57-module-migrations-20261009 合并提交至个人分支，未重置或强推。基线验证：工作经历相关Maven测试113项通过、2项跳过，排除1项需Docker的Redis集成测试；OpenAPI校验通过（213 paths/261 operations）。AI-003实现、扩展验证与交付文档进行中。模型评测、前端联调、供应商正式告知核实及生产验收仍未完成。

+# AI-004 简历模块批量AI优化实现方案
+
+版本：v1.1；日期：2026-10-29（Asia/Shanghai）；状态：2026-10-29用户已批准执行，并明确三个总入口绑定同一流程；本批后端复核及对接文档已交付，未修改代码，前端实施和联调待完成。
+
+本版整体替代v1.0。为保留已有文档链接，沿用文件名“AI-004-整份简历AI一键优化-实现方案.md”，正文以本版模块批量编排为准；v1.0的整份草稿、整份模型调用、新增整份提示词、技能优化及两个新接口全部撤回，不属于本版范围。
+
+## 1. 页面事实与目标
+
+用户提供的两张页面设计图表明：简历按基本信息、求职意向、教育、工作、实习、项目、技能、自评和附件分模块展示及编辑；工作、实习已有AI优化入口，自评有AI润色入口。项目为空时未展示AI按钮，项目优化能力依据现有AI-003代码核查，不从截图推断已完成联调。技能只有添加入口，本任务不新增技能AI能力。
+
+按用户明确说明，“优化简历”和底部“AI一键优化”是同一功能。用户已明确页面中间的“一键全部优化”入口也绑定同一流程，三个入口不另外设计不同功能。简历评分“暂未开放”不属于本任务，不引入评分接口或把优化结果当分数。
+
+目标是一次触发所有已接入AI优化模块的批量处理，各条目分别生成建议、分别展示，用户可以逐一确认、修改、采用或取消，保存沿用各模块现有流程。不存在整份简历编辑草稿前提；仅在用户查看/修改某项建议时产生该模块临时待确认内容。
+
+## 2. 建议实现与取舍
+
+推荐第一版采用“前端统一队列，复用现有模块接口”。业务上一次启动全部优化，执行上依次调用、逐项返回，不将“同时调用”实现为无上限并发。理由是现有后端真实模型限流器对同一用户仅允许一个在途调用，直接Promise.all会使多数请求429；工作经历默认每分钟3次、每天20次，长队列也可能触发额度。第一版不为此调整旧限额或改变其他AI功能。
+
+每次批量处理按页面顺序建立固定条目清单：工作经历→实习经历→项目经历→自我评价。同一模块多条经历逐条处理，结果携带前端已有条目映射，不合并多条正文交给单段接口。任务执行顺序不代表展示优先级，前端可边显示结果边处理下一项，用户不必确认完第一项才允许生成下一项。
+
+本方案不新增后端批量路由、任务表、轮询接口或SSE；不在后端通过HTTP调用自己。直接复用原AI服务及提示词可避免重写一套语义、隐私校验和保存逻辑。后续若明确要求退出页面继续运行、后台任务恢复、服务端统一调度或大量条目快速处理，再单独设计后端批量任务，不提前建设。
+
+代价：队列由前端负责人实现；页面关闭不保证继续，已发出的外呼不保证取消或退费；多条调用有多次耗时和成本，不能宣传一次总调用或无限次数。本工作区提供契约、批量规则和联调支持，不修改前端代码。
+
+## 3. 后端复用清单与当前状态
+
+实际Git开发仓库：D:/巴适/轻松聘-ai智能助手；本轮只读核查HEAD为ff52692，有AI-003未提交生产/测试/契约文件，不覆盖或清理。工作区zhangshun是较旧参考副本。正式开发前复核分支、指引和既有修改。
+
+| 页面模块 | 复用POST（均加/api/v1） | 当前限制与状态 |
+| --- | --- | --- |
+| 工作经历 | /profile/me/work-experience-optimization | position≤100、description非空≤3000、targetPosition≤100；已有代码 |
+| 实习经历 | /profile/me/work-experience-optimization | 同样是经历描述优化；保留原experienceType=INTERNSHIP和原条目身份，不另建实习AI服务 |
+| 项目经历 | /profile/me/project-experience-optimization | description非空≤5000；projectName≤150、role≤120、targetPosition≤120；AI-003候选实现待验收 |
+| 自我评价 | /profile/me/self-evaluation-optimization | description非空≤5000、targetPosition≤120；AI-003候选实现待验收 |
+
+每条POST对应GET同路径/notice。全部使用现有Authorization: Bearer <access-token>，仅STUDENT本人；不传userId。使用现有ApiResponse，code/message/data/requestId/timestamp。同步JSON，无分页、无流式输出。
+
+工作/实习字段与在线简历字段上限不完全一致（原position允许120、描述5000，AI仅100/3000）；批量调用不能截断或绕过校验。超出原AI预算的条目标记“内容超限，需单独调整后优化”，保留原文，其他合法项继续。若产品要求所有现有合法长度都能优化，必须单独修改旧AI契约并审批，不在本版暗改。
+
+项目与自评已有候选实现并不代表完成交付：工作记录中AI-003有测试设施问题和待批准修复。本版不替代该审批，也不在未验收时把入口标记可用。批量上线以相关模块实际可用为前提。
+
+## 4. 调用、告知和返回示例
+
+本版无新增或修改后端接口。以下为复用契约的合成示例，不是新批量请求。
+
+工作/实习请求：
+```json
+{"position":"后端开发实习生","description":"参与订单查询接口开发，补充接口测试。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"work-experience-external-processing-v2"}
+```
+实际工作经历告知版本以GET /notice返回为准，客户端不硬编码本示例。
+
+项目请求：
+```json
+{"projectName":"课程商城","role":"参与开发","description":"使用Java实现订单查询接口，尚未上线。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"project-experience-external-processing-v1"}
+```
+自评请求：
+```json
+{"description":"学习Java和SQL，在课程项目中编写接口测试。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"self-evaluation-external-processing-v1"}
+```
+成功响应示例：
+```json
+{"code":200,"message":"ok","data":{"status":"OPTIMIZED","optimizedDescription":"参与订单查询接口开发，并补充接口测试。","suggestions":[],"followUpQuestions":[],"promptVersion":"work-experience-deepseek-v2","simulated":false},"requestId":"example","timestamp":"2026-10-29T02:00:00Z"}
+```
+status、promptVersion与simulated以实际各模块返回为准；NEED_MORE_INFO时展示followUpQuestions，不采用空正文；simulated=true须标模拟，不宣称真实优化完成。实际工作经历schema和告知版本在交付前按对应源码/OpenAPI再次核对。
+
+批量开始先获取清单涉及场景的notice，按场景展示用途、供应商、外传字段和当前版本。本次可以在一个清晰的确认界面列出全部条目及涉及场景，用户明确同意本次列出的处理后，逐条附带对应版本和原生布尔true；不能把一次同意变成长期授权，不包含后续新增条目。跨场景版本不能混用，过期时暂停受影响项并重新告知。告知是否允许统一批次确认还需核对现有各场景正式告知措辞；不能默默改变“每次调用确认”的既有约定。前端可先采用逐项确认，待告知条款确认后使用批次确认。
+
+不传姓名、电话、邮箱、附件、账号信息或整份简历；项目名可用脱敏代称，正文不得包含凭据或他人资料。保留现有输入安全和输出校验，不新增提示词或供应商。真实模式仍以前置授权及供应商处理政策核实为开放条件，不默认用真实用户数据试验。
+
+## 5. 批量流程与结果确认
+
+1. 从当前页面已经读取的模块数据建立本次清单；必要时沿用原读取接口刷新，避免强制进入整份编辑。记录条目id、模块、原描述及当前版本供前端关联，不把这些身份字段强塞给现有AI DTO。
+2. 只包含已接入AI的工作/实习/项目/自评。空模块、正文为空和“无”等无事实占位内容不自动生成，提示补充或标记跳过；不凭其他模块信息擅自生成空自评。未来跨模块生成是另一个契约。
+3. 展示本次条目数量、外部处理告知及可能多次调用，用户启动后锁定批次清单。顶部、底部和中间总入口共用一个运行状态，避免重复创建队列；单项按钮与批量请求也需协调，避免同用户并发触发429。
+4. 每完成一条立即显示原文/优化建议/补充问题，允许用户查看、修改、采用、取消；后台继续下一合法条目。不能只有最后全部结束才展示，也不把一个失败视为全批失败。
+5. 采用前核对目标条目仍存在且描述仍与提交时一致；用户期间编辑、删除或切换条目时标记结果过期，不能按数组下标回填。临时关联对象仅存在前端，不新增后端历史表。
+6. 采用后进入该模块原有编辑/保存流程。工作/实习/项目只修改description，自评修改selfEvaluation，保留其他字段。用户继续编辑后再保存，或沿用原页面明确的确认保存动作。
+7. 原条目PUT为完整替换，要保留完整条目、id、experienceType、日期和最近revision；自评若沿用原整份保存工具，须由原工具保留其他模块，不能只提交selfEvaluation造成字段清空。任何新保存接口或改变原保存语义都不属于本任务。
+8. 多项采用保存必须协调同一份在线简历的revision：每次成功后更新本地版本，再保存下一项，不能让所有保存使用同一个旧revision。409/6002保留待确认内容、重新读取并让用户处理冲突，不自动换版本覆盖。
+
+逐一确认是交互要求，不要求模型输出每个token实时返回；复用单条HTTP响应即可实现逐项展示。
+
+## 6. 失败、额度与取消规则
+
+前端本地状态建议：待处理、处理中、待确认、需补充、已跳过、失败、已取消；属于队列展示状态，不冒充后端新增status。用户确认及保存状态与生成状态分别记录，生成成功不等于采用或保存。
+
+单项400标记失败并继续其他合法项；502/504保留原文、允许用户单独重试，不自动再次计费；401停止队列走原登录流程；403停止并提示权限；503暂停并提示服务/模块不可用，不持续外呼。429停止当前自动派发，展示Retry-After和已完成结果，后续由用户选择继续，避免紧密循环重试；日额度耗尽不承诺等60秒一定恢复。重试与继续应覆盖当次有效告知范围，必要时重新确认。
+
+空模块跳过；单项没有结果不影响已有建议；用户取消停止未开始的请求，已返回建议可保留供本人确认，但不继续自动调用。页面离开时停止调度，不承诺后台持续运行。前端不得为了避免429另换入口或账号，也不降低旧限流。
+
+本版复用原模型调用、限流、输入校验和提示词，原单项契约不变；批量触发仍会消耗共享额度，属于必须明确的资源影响。无法在不改限额的前提下承诺任意多条一次点击全部成功；页面需要显示完成数、失败数和待处理数。
+
+## 7. 文件、配置和职责范围
+
+当前批次仅修订根文档和工作记录，不改生产/测试代码；无数据库、依赖、配置、外部服务、提示词或接口变化，无文件删除。
+
+本轮实际修改：
+- D:/巴适/轻松聘/docs/AI-004-整份简历AI一键优化-实现方案.md：v1.1整体替代旧设计。
+- D:/巴适/轻松聘/工作记录.txt：追加本次纠正、证据和状态。
+
+方案确认后后端侧拟交付：
+- docs/AI-004-简历模块批量AI优化-前端对接方案.md：模块映射、请求示例、队列/采用/保存约束、错误与额度处理。
+- docs/AI-004-简历模块批量AI优化-后端整合说明.md：现有接口复用、实际依赖状态、测试与联调证据、不新增代码的说明。
+
+前端负责人实施统一队列、入口绑定、进度、逐项确认及原保存调用，本工作区不列出未知前端文件名，不要求完整前端仓库作为文档交付前置。待前端提供必要调用片段或契约后可继续核对。
+
+AI-003修复/验收按其独立方案处理。本版不新增ResumeOptimization*生产类，不修改旧客户端、全局认证、评分、保存服务或OpenAPI；后续核查如发现确有后端缺口，先列明精确文件、影响和方案再审批。
+
+## 8. 验证、验收与回滚
+
+本轮已核对用户页面及说明、原在线简历分模块结构和保存契约、现有工作经历请求DTO、项目/自评场景类型。纯文档不运行整套后端测试；未调用模型，未开展页面联调或真实Redis/MySQL验收，不沿用历史通过数量宣称本次通过。
+
+后续联调重点：总入口触发同一队列；工作与实习条目正确映射；多条逐项返回；空模块跳过；单项失败保留其他结果；429暂停；取消停止新派发；重复点击不重复调用；用户编辑/删除后旧结果不覆盖；逐项编辑/采用/保存使用原工具及正确revision；刷新后读取与用户确认一致；原单项AI按钮及其他业务行为保持。
+
+AI-003测试、模型质量和供应商告知核实分别有证据才标通过，不用前端队列掩盖后端未交付状态。真实评测使用合成样本，需记录提示词/模型版本、事实漂移、延迟和调用消耗。
+
+回滚由前端移除总入口队列绑定、恢复既有入口行为，保留单项AI和原保存；后端无新增表或代码需要回滚。不删除已经由用户确认保存的内容。任何后续代码批次按AGENTS.md先方案审批。
+
+## 9. 本版结论与审批范围
+
+“优化简历”“AI一键优化”（建议包括“一键全部优化”）统一为已有AI模块的批量入口，各条目复用原接口与提示词，逐条生成、逐条确认、允许修改、原工具保存。技术上采用受控串行队列，避免现有同用户并发限制导致大量失败。
+
+本版取代v1.0，用户已批准执行并确认三个入口共用流程。批准本版不等于授权修改前端或修复AI-003；后端若无需新增代码，则主要交付对接契约和联调支持，不为了制造新接口重复建设。尚待确认的是前端原保存调用细节、批次告知措辞与AI-003最终可用状态，不阻塞当前方案修订。
+
+
+## 10. 2026-10-29执行与交付记录
+
+用户明确批准执行v1.1，并确认“一键全部优化”也绑定同一流程。按本版无新增后端代码的范围完成实际接口、告知、DTO、限流和保存契约复核，并生成同编号前端对接方案和后端整合说明。
+
+复核纠正：工作经历当前告知版本为work-experience-external-processing-v2，前端必须读取notice.data.version；现有响应只支持OPTIMIZED/NEED_MORE_INFO，不使用v1.0的UNCHANGED；现有告知逐次同意，交付默认逐项明确授权，不把总入口点击当作所有外传同意。串行仍可能达到每分钟配额，对接文档补充默认额度下的调用节奏及429暂停/手动继续。
+
+2026-10-29实际仓库运行python ./docs/verify_openapi.py，退出码0，217 paths/265 operations，All checks passed。此为静态验证，不是HTTP/页面验收。本轮未运行Maven、未启动服务、未调用模型、未改代码或配置、未提交推送部署。
+
+交付：docs/AI-004-简历模块批量AI优化-前端对接方案.md、docs/AI-004-简历模块批量AI优化-后端整合说明.md。后端复核/文档范围已完成；前端三个按钮绑定、队列、联调、AI-003独立修复验收和真实模型生产放行仍未完成，不能标成页面功能已经上线。

+# AI-004 简历模块批量 AI 优化前端对接方案
+
+日期：2026-10-29（Asia/Shanghai）。依据：用户已批准AI-004 v1.1，并明确三个总入口使用同一流程。状态：接口与调用契约已按当前源码及静态OpenAPI复核；前端队列尚未实施/联调，AI-003仍为未完成验收的候选实现。本文件不代表页面功能已上线。
+
+## 1. 三个入口与功能范围
+
+“优化简历”“AI一键优化”“一键全部优化”共用同一批量启动处理函数、队列和运行状态，不分别创建请求流程。任一入口触发后，其他总入口显示同一进度并防止重复创建批次。原模块AI按钮继续提供单项优化，但与批量队列共用该页面的请求调度，避免同用户同时发起两个真实请求。
+
+处理顺序：工作经历各条→实习经历各条→项目经历各条→自我评价。每次提交一条，每返回一条立即展示，不等待整个批次完成。用户确认建议与生成后续建议可交错进行。
+
+只处理有原文且已具备AI接口的模块。空白、明确无事实的占位内容跳过并解释；不增加技能优化，不生成空经历或空自评，不解析附件，不关联评分。工作和实习均来自现有workExperiences，按experienceType及页面既有分类处理；同一条id只进入一次，不能因分别扫描两个列表重复优化。类型未区分时沿用原页面分类，不推断为实习或改写类型。
+
+## 2. 环境、鉴权与实际接口
+
+将下列路径拼接到团队确认的后端origin，例如本机确实已启动服务时可使用 `http://127.0.0.1:8080`。本轮未启动服务或确认该地址在线；不要把示例当作当前可用联调环境。
+
+全部请求使用 `Authorization: Bearer <access-token>`；POST使用 `Content-Type: application/json`。限STUDENT本人，不提交userId。不把token、简历文本或模型响应写入普通日志/埋点。同步JSON，无分页、无SSE、无新增批量路由。
+
+| 模块 | GET告知 | POST生成 |
+| --- | --- | --- |
+| 工作/实习 | `/api/v1/profile/me/work-experience-optimization/notice` | `/api/v1/profile/me/work-experience-optimization` |
+| 项目 | `/api/v1/profile/me/project-experience-optimization/notice` | `/api/v1/profile/me/project-experience-optimization` |
+| 自评 | `/api/v1/profile/me/self-evaluation-optimization/notice` | `/api/v1/profile/me/self-evaluation-optimization` |
+
+notice使用ApiResponse包装，data含 `version,title,provider,purpose,dataFields,message,mode,enabled,developmentOnly`。注意实际字段是 **version**，POST映射为 **consentNoticeVersion**；不存在新设计的retentionPolicyStatus或resume总场景notice。不能仅凭developmentOnly=false或enabled=true认定供应商正式政策、生产验收已完成。
+
+当前源码版本：工作/实习 `work-experience-external-processing-v2`；项目 `project-experience-external-processing-v1`；自评 `self-evaluation-external-processing-v1`。客户端必须读取notice.data.version，不硬编码版本。
+
+## 3. 输入字段与映射
+
+| 场景 | 业务字段及长度 | 从页面读取 |
+| --- | --- | --- |
+| 工作/实习 | position可选≤100；description必填非空≤3000；targetPosition可选≤100 | 当前条目position、description；当前求职意向targetPosition |
+| 项目 | projectName可选≤150；role可选≤120；description必填非空≤5000；targetPosition可选≤120 | 当前项目name映射projectName，role及description |
+| 自评 | description必填非空≤5000；targetPosition可选≤120 | selfEvaluation映射description |
+
+各场景另有两个必填字段：externalProcessingConsent为原生JSON布尔true；consentNoticeVersion为该场景当前notice版本。字符串"true"、false、数字、null或缺失不合法。长度按Java字符串UTF-16长度；不自动截断。现有在线简历工作position/description上限大于工作AI上限，超出时标记待调整，不能截取后悄悄提交。可选目标岗位超限也不能自动截断，提示用户缩短或明确不提交该可选项。
+
+仅发送上表及两个告知字段。条目id、revision、批次id、本地关联key、experienceType、公司、日期、姓名、联系方式、附件和完整简历不属于AI请求。条目映射保存在前端本次任务内存中，通过发起调用的任务对象关联响应，后端不会返回条目id。
+
+工作/实习合成示例（代码中的noticeVersion变量来自GET告知）：
+
+```javascript
+const body = {
+  position: entry.position,
+  description: entry.description,
+  targetPosition: targetPosition || null,
+  externalProcessingConsent: true, // 仅在用户已明确同意该次请求后构造
+  consentNoticeVersion: noticeVersion
+};
+```
+
+项目合成JSON：
+
+```json
+{"projectName":"课程商城","role":"参与开发","description":"使用Java实现订单查询接口，尚未上线。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"project-experience-external-processing-v1"}
+```
+
+自评合成JSON：
+
+```json
+{"description":"学习Java和SQL，在课程项目中编写接口测试。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"self-evaluation-external-processing-v1"}
+```
+
+## 4. 告知与任务授权
+
+当前正式代码告知写明“同意仅针对本次优化请求”，本次交付不改该约定。采用逐项明确同意：在每项派发前展示对应告知及处理条目，用户选择本次同意后调用；用户拒绝则跳过该项，继续下一项。可以用持续更新的单个确认面板避免重复弹窗，但不能自动勾选、把“点击总入口”当成外传同意或复用上次单项同意。
+
+将“已读取该场景notice”与“用户已同意某条请求”分开保存。notice可在同批次同场景复用读取结果；若收到告知失效相关400，刷新notice、重新展示，让用户再次确认，不静默重试。现有400并无专门子码标明是否告知过期，不能把所有400都解释为版本过期，应先比较新notice版本及检查本地输入，仍无法判断则展示安全错误和requestId。
+
+“一个界面勾选全部条目一次授权自动派发”的体验没有在本次交付中认定为满足既有每次请求告知；若要采用，须先明确其条目范围及正式告知规则再更新对接约定。用户逐一确认优化结果与用户同意向第三方处理是两个不同动作。
+
+## 5. 队列、调用节奏与结果
+
+进入批次时固定清单，每项保留本地taskKey、场景、条目id或本地稳定key、原文、请求字段快照及generation。这些字段不发给AI。批次进行中新增的经历不自动加入已获同意的清单，另起处理。
+
+全页面同一时刻最多一条AI请求。真实模式默认限额为每用户3次/分钟、20次/天、全局200次/天、全局并发4，均是现有配置默认值，部署可能覆盖。计数按Redis时间固定窗口、日窗口为UTC；不要展示北京时间零点必定恢复。notice不返回额度余额，页面不能显示虚构的“剩余次数”。
+
+若联调确认为默认3次/分钟，可将真实请求开始间隔至少21秒，模型调用耗时和等待用户确认均计入间隔；部署限额不同则由前端按联调配置调整。此为减少429的调度建议，不能消除其他页面、其他入口、全局或日限额竞争，仍必须处理429。stub模式无需人为等待21秒。等待以可取消的异步计时器实现，不阻塞页面，不同时派发多条。
+
+所有生成响应沿用以下结构：
+
+```json
+{"code":200,"message":"ok","data":{"status":"OPTIMIZED","optimizedDescription":"参与订单查询接口开发，并补充接口测试。","suggestions":[],"followUpQuestions":[],"promptVersion":"work-experience-deepseek-v2","simulated":false},"requestId":"example","timestamp":"2026-10-29T02:00:00Z"}
+```
+
+| 返回内容 | 界面处理 |
+| --- | --- |
+| OPTIMIZED且有正文 | 显示原文和建议，进入待确认 |
+| NEED_MORE_INFO | 显示问题；optimizedDescription可能省略或null，禁止清空原字段 |
+| simulated=true | 显示模拟标识；可能仍为OPTIMIZED并原样返回原文，不宣称润色成功 |
+| simulated=false | 仅说明当前模式；本地规则可能直接返回，不证明本次实际外呼 |
+| 未知status或结构不完整 | 视为本项异常，不回填、不保存，保留原文 |
+
+现有接口没有UNCHANGED或批量status，不创建假后端状态。前端自身可使用待处理、等待同意、等待额度、处理中、待确认、需补充、失败、跳过、取消；采用和保存另记状态。进度分别显示“已处理/总项”“生成建议数”“待确认数”“已保存数”，不能把生成成功展示为保存成功。
+
+用户取消时停止尚未派发的调用；给正在执行的task标记失效，晚到响应不覆盖新批次。AbortController可停止等待，但不保证供应商停止计算或退费。不自动持久化正文到localStorage/IndexedDB；页面离开、账号退出清理内存建议，不承诺离开后继续运行。
+
+## 6. 逐项确认、编辑与原保存
+
+每项结果有查看、修改建议、采用、取消。修改后的建议仍受原模块字段长度限制。采用前对比稳定条目身份和目标原文；描述已编辑、条目删除或用户切换账号时标记过期，允许查看/复制但不自动覆盖。不能按数组下标定位条目，也不能用其他条目的建议替换它。
+
+工作/实习/项目仅回填description，自评仅回填selfEvaluation。不要求页面进入整份简历编辑。用户采用后可以继续编辑；保存走原模块工具。若该工具为“确认即保存”，按钮需明确含保存动作，由其原有行为执行，不新增AI自动保存请求。
+
+已核查的后端保存契约：
+
+| 方法/路径 | 用途与注意 |
+| --- | --- |
+| GET `/api/v1/profile/me/online-resume` | 读取content与全局revision |
+| PUT `/api/v1/profile/me/online-resume/work-experiences/{id}` | 工作/实习条目完整替换，请求为revision、entry |
+| PUT `/api/v1/profile/me/online-resume/project-experiences/{id}` | 项目条目完整替换，请求为revision、entry |
+| PUT `/api/v1/profile/me/online-resume` | 现有完整保存；自评没有独立section写接口，原工具若使用此接口必须保留全部content |
+
+条目保存合成示例：
+
+```json
+{"revision":3,"entry":{"id":"11111111-1111-1111-1111-111111111111","company":"示例公司","position":"实习开发","startDate":"2026-01-01","endDate":null,"ongoing":true,"experienceType":"INTERNSHIP","description":"用户确认并编辑后的描述"}}
+```
+
+这是示例字段值，不可用示例id调用真实保存。实际应完整复制原条目所有业务字段，只替换目标描述。新条目没有服务器id时沿用原新增工具，不伪造id。
+
+保存响应data是更新后的完整OnlineResumeView（revision、content、attachment、updatedAt）；下一项采用保存以新revision为准，同时保留其他尚未保存的建议/编辑状态，不能刷新视图时丢掉它们。所有页面保存共用串行写入管理，不能让两个保存请求同时使用旧revision。HTTP409/code6002需重新读取并人工合并，HTTP404/code6003表示条目不存在，禁止改为创建或强行覆盖。
+
+自评完整保存只提交 `{revision,content}`，content为原工具维护的完整最新内容，不能只构造selfEvaluation一个字段。其他模块在生成期间已被保存的变动也要保留。前端实际使用哪个原工具及其返回处理仍需负责人用调用片段联调确认，不因后端提供整份PUT就改变页面编辑方式。
+
+## 7. 错误、超时、重试
+
+按HTTP状态和现有业务码共同处理，不能只判断code是否等于HTTP状态。错误data可能因NON_NULL省略。
+
+| HTTP | 行为 |
+| --- | --- |
+| 400（可能code400/1001） | 本项失败；保留原文，检查长度/敏感输入/同意/版本；继续其他合法项，不自动重试 |
+| 401 | 停止队列，走原会话流程；新账号不得继承旧队列 |
+| 403（角色可能code2002）/404用户不存在 | 停止队列，提示权限或账号不可用 |
+| 429 | 暂停派发，保留所有结果；当前返回Retry-After:60，倒计时后允许手动继续，不保证日额度已恢复 |
+| 502/504或网络超时 | 当前项失败，保留其他结果；允许单项手动重试，重新明确同意，不后台补发 |
+| 503 | 暂停队列并提示模块关闭/配置/Redis/上游问题，不循环重试；可由用户跳过不可用场景 |
+| 500 | 保留当前结果和原文，暂停并展示requestId，供联调定位 |
+
+模型默认超时20秒，可配置1–60秒；前端请求超时需高于实际后端超时并留网络余量，不把请求超时设为整个批次超时。多条队列总时长可能更长，持续显示进度及取消入口。计费是否发生不能仅凭超时或simulated=false判断。
+
+## 8. 联调验收清单与状态
+
+已完成：按源码复核六条AI路由、告知字段/版本、请求上限、响应、角色和错误；现有OpenAPI脚本2026-10-29运行通过（217 paths/265 operations）。这属于静态契约验证，不代表服务已部署。
+
+待前端负责人联调：三个总入口同队列；工作/实习去重；逐条返回与逐项授权；空模块/不可用场景；超长输入不截断；429暂停/继续；取消和晚到结果；编辑后过期提示；确认后继续改写；保存串行revision；409冲突；保存后重开回读；评分、技能、附件及原单项按钮不被改变。
+
+当前无已确认的在线联调URL；AI-003有未完成验收事项，真实模型质量、供应商正式告知、Redis运行验证和页面验收本轮未执行。先在团队可用stub环境验证契约和交互，模拟结果必须标注；真实模式开放由负责人在既有验收完成后决定。

+# AI-004 简历模块批量 AI 优化后端整合说明
+
+日期：2026-10-29（Asia/Shanghai）；对应方案：AI-004 v1.1，用户已批准，并确认“优化简历”“AI一键优化”“一键全部优化”绑定同一流程。
+
+本批后端侧交付为接口复核与对接契约：复用已有工作/实习、项目、自评AI接口，由前端统一队列逐条处理和确认。无新增后端生产/测试代码、数据库、依赖或配置，不能将本说明解释为前端已绑定、服务已部署或AI-003已经验收。
+
+## 1. 仓库、结构与依赖状态
+
+实际开发仓库：`D:/巴适/轻松聘-ai智能助手`；本轮核查HEAD为 `ff52692`（合并整合分支的既有提交）。根工作区 `D:/巴适/轻松聘/zhangshun` 为历史参考副本，不是本次代码整合目标。本轮未切换分支、fetch、合并、暂存、提交、推送或部署。
+
+现有包 `mydreamjob-server/src/main/java/com/mydreamjob/resume/optimization/` 负责模型建议：WorkExperienceOptimizationController/Service及相关DTO处理工作和实习；ResumeSectionOptimizationController/Service及相关DTO处理项目与自评；各自Router、ModelClient、提示词处理建议；共享WorkExperienceCallLimiter负责真实调用原子额度和并发租约。
+
+`onlineresume/OnlineResumeController`、`OnlineResumeService`、`OnlineResumeContent`、`OnlineResumeSaveRequest` 提供既有本人简历读取、条目及完整保存、revision并发控制。AI不写入这些服务，也不替代原评分、权限或保存逻辑。
+
+仓库进入本任务前已有AI-003未提交文件（ResumeSection生产代码、四份提示词、八份测试）及docs/openapi-rc.json、docs/resume-api.md、docs/verify_openapi.py修改。本任务保留这些状态；不得把“本次未改代码”误解为仓库原本干净。
+
+工作记录及AI-003 v1.2文档显示，其首轮新测试有两项Mockito测试设施错误、Redis环境跳过及旧安全集成测试接口数量适配问题，补充修复尚待单独审批。本批不修复、不提交这些文件，不冒充AI-004依赖已验收。
+
+## 2. 接口与复用边界
+
+AI路由均使用现有 `/api/v1/profile/me` 前缀和Bearer access-token、STUDENT本人权限：
+
+- 工作/实习：GET `/work-experience-optimization/notice`，POST `/work-experience-optimization`。
+- 项目：GET `/project-experience-optimization/notice`，POST `/project-experience-optimization`。
+- 自评：GET `/self-evaluation-optimization/notice`，POST `/self-evaluation-optimization`。
+
+工作/实习告知当前为v2，项目/自评各为v1；前端必须取notice.data.version。三种POST返回OPTIMIZED/NEED_MORE_INFO、optimizedDescription、suggestions、followUpQuestions、promptVersion及simulated，不新增批量响应或UNCHANGED。请求上限、完整示例及错误详见同编号前端对接方案。
+
+页面“同时优化所有模块”落实为一次启动队列，执行上同用户串行。工作和实习对应同一接口及同一原条目集合，必须去重。每项返回立即可供用户确认/编辑，某项失败不抹除其他结果；采用后走原模块保存。页面评分、技能、教育、附件不扩展。
+
+现有工作AI position≤100、description≤3000，与在线简历position≤120、description≤5000有差异；保留旧契约，超长项提示调整。项目/自评description≤5000。不得静默截断或修改旧限制。
+
+当前告知要求每次请求明确同意，交付默认逐项授权，不默认一次点击总按钮即同意所有外传。统一批次授权需另行明确正式告知，不能只改前端文案就绕过既有规则。
+
+## 3. 配置、启动与数据
+
+无新增配置、依赖、表、迁移或独立服务；没有新的启动命令。继续按实际仓库README配置Java17/Maven及原MySQL/Redis/RabbitMQ/JWT环境。本轮不启停基础设施、不开启真实模式、不展示或写入凭据。
+
+沿用 `ai.work-experience.mode`、`ai.project-experience.mode`、`ai.self-evaluation.mode`，取off/stub/deepseek。真实模式要求对应real-enabled=true及原有DeepSeek配置；默认关闭，不能为联调自动打开真实模型。工作入口仍有旧stub-enabled兼容开关，优先明确mode避免歧义。
+
+沿用DEEPSEEK_API_KEY、DEEPSEEK_MODEL、DEEPSEEK_TIMEOUT_SECONDS，本轮不调整或核验型号能力和价格。供应商留存、训练用途及正式授权仍需既有开放流程核实。
+
+限额继续取 `ai.work-experience.limits.*`，默认user-per-minute=3、user-per-day=20、global-per-day=200、global-concurrency=4，单用户在途上限1；项目、自评、工作、实习共享。Redis固定UTC时间窗口计数不等于北京时间自然日；Retry-After=60不能表达日额度剩余。批量增加调用量，仍可能限制其他AI入口的可用次数；不承诺零资源影响。
+
+没有AI正文持久化。前端临时建议仅保存在本次内存任务，用户确认并通过原保存接口写入后，按原在线简历数据政策处理。本批不新增历史、缓存或数据导出字段。
+
+## 4. 原保存整合
+
+沿用GET `/api/v1/profile/me/online-resume` 返回revision/content。工作、实习使用原 `PUT /api/v1/profile/me/online-resume/work-experiences/{id}`；项目使用project-experiences/{id}。请求revision+完整entry，不能只提交description。
+
+自评没有独立self-evaluation条目保存接口；原工具若使用完整PUT，必须传完整content，只替换selfEvaluation。完整PUT是原业务契约，不代表本页面需要改成整份编辑；未知的前端封装不在本任务凭空重建。
+
+多个模块共享revision，前端原保存必须串行并以每次返回值更新版本。409/6002保留人工修改并重新读取合并；404/6003不自动创建替代条目。用户生成期间编辑或删除条目时，旧结果须过期，不按数组下标覆盖。原experienceType、公司、岗位、日期及其他字段全部保留。
+
+## 5. 本批文件与Gitea交付
+
+实际文件均在工作区根 `D:/巴适/轻松聘`：
+
+- docs/AI-004-整份简历AI一键优化-实现方案.md：v1.1批准状态、三个入口和本次执行记录；文件名保留原链接，正文为模块批量流程。
+- docs/AI-004-简历模块批量AI优化-前端对接方案.md：本次新增，提供前端调用、授权、调度、逐项确认与原保存规则。
+- docs/AI-004-简历模块批量AI优化-后端整合说明.md：本次新增，即本文件。
+- 工作记录.txt：追加本次审批、变更、验证和待办，保留旧记录。
+
+实际仓库无本批生产代码diff，因此没有AI-004代码分支或提交可以声称已合入。用户未要求本次上传、推送或合并；文档保存在根docs，交付时将三份AI-004文档作为同一组提供给负责人。需要同步到Gitea时，依当时明确指令精确选择文件，不能git add -A把AI-003候选改动一并带入。
+
+## 6. 验证结果与整合顺序
+
+2026-10-29在实际仓库执行 `python ./docs/verify_openapi.py`：退出码0，217 paths / 265 operations，All checks passed。同时按源码核对六条AI路由、notice版本、请求DTO及响应DTO、异常映射、限流默认值和保存控制器。静态校验包含AI-003候选契约，不等于运行时或部署验收。
+
+本批仅文档，无需为其运行整套Maven；本轮未运行单元/集成测试、未启动HTTP服务、未外呼模型，未执行真实Redis/MySQL或前端页面验收。历史测试结果仍以AI-003记录为准，不能标成本轮通过。
+
+建议负责人依次：
+
+1. 确认要联调的后端版本已包含并完成AI-003独立修复/验收；保留现有个人分支和未提交差异。
+2. 在团队可用测试环境按既有方式启动服务，先使用各场景stub，不自动开放真实模式。
+3. 将同编号前端对接方案交给前端负责人，实现三个入口共用队列和逐条确认；本助手本轮未发送消息给其他人。
+4. 验证六路由鉴权与响应、模块映射、超长项、逐次同意、429/超时/取消、原单项按钮和原保存revision冲突。
+5. 页面确认后保存再打开回读，并核对原评分、附件和其他字段未被影响。
+6. 真实模型质量、费用、耗时、供应商正式告知及生产放行单独记录；先用合成数据评测，不默认上传真实资料。
+
+## 7. 冲突、回滚和未完成事项
+
+潜在冲突为AI-003未完成验收、多人共享OpenAPI文档、前端全局revision更新及共享AI额度。本批没有修改共享生产代码或契约，不为此合并或清理旧差异。
+
+前端回滚可移除批量总入口绑定、恢复原单项入口；保留原简历保存及用户已确认写入的数据。后端无本批迁移或新增代码需要回滚。
+
+已完成的是AI-004后端复用复核和两份交付文档。尚未完成的是前端三个入口的实际绑定和队列、前后端联调、AI-003独立验收、真实模型评测及生产开放。前端负责人只需确认当前模块数据和保存工具的必要调用契约，不要求提供完整前端仓库；如发现必须改后端才能满足的缺口，按新的精确方案审批，不扩大本批范围。

+全部使用现有 Bearer Access Token，仅 STUDENT 本人；不接收 userId、不扫描整份简历、不写库。notice 在 off 模式仍可查看。
+项目请求：`projectName` 可选≤150、`role` 可选≤120、`description` 必填非空≤5000、`targetPosition` 可选≤120。
+自评请求：`description` 必填非空≤5000、`targetPosition` 可选≤120。
+两者均必须携带原生 JSON 布尔 `externalProcessingConsent:true`（字符串、数字、false、null、缺失均拒绝），以及对应当前 `consentNoticeVersion`：项目 `project-experience-external-processing-v1`；自评 `self-evaluation-external-processing-v1`。跨场景、缺失、过期版本返回400。
+
+合成项目请求示例：
+```json
+{"projectName":"课程商城","role":"参与开发","description":"使用Java实现订单查询接口，协助编写测试并修复分页问题，尚未上线。","targetPosition":"Java后端开发","externalProcessingConsent":true,"consentNoticeVersion":"project-experience-external-processing-v1"}
+```
+
+返回现有 `ApiResponse` 包装，data 包含 `status`（OPTIMIZED/NEED_MORE_INFO）、`optimizedDescription`（不足事实时为null或省略）、`suggestions`、`followUpQuestions`、`promptVersion`、`simulated`。真实版本分别为 `project-experience-deepseek-v1`、`self-evaluation-deepseek-v1`；模拟版本去掉 `deepseek-`。模拟返回原文，不能当成模型优化结果。`simulated=false` 只表示真实模式；本地信息不足路径不会外呼。
+
+默认 `ai.project-experience.mode=off`、`ai.self-evaluation.mode=off`，可各自设 `stub` 联调。真实模式各自设 `mode=deepseek` 与 `real-enabled=true`，复用现有 DEEPSEEK_API_KEY/MODEL/TIMEOUT_SECONDS；无新增数据库或依赖。不修改原工作经历配置。三项能力共享原 `ai.work-experience.limits.*` Redis额度与租约，默认每用户3次/分钟、20次/日、全局200次/日、全局同时4次、每用户同时1次、租约75秒；接受调用消耗额度，释放不退额。Redis不可用失败关闭，不自动重试。
+
+错误：400 参数/同意/敏感输入，401 会话，403 角色，404 用户不存在，429 配额/并发（Retry-After:60），502 无效模型输出，503 off/配置/Redis/上游不可用，504 超时。保留原文，429不自动重试；其他失败由用户手动重试并确认当次同意。不把供应商异常正文回显给前端。
+
+采用项目建议仅回填既有项目条目的 `description`；自评建议回填 `selfEvaluation`。用户仍经原保存接口提交，保留原id、其他字段和最近revision；409应重新读取并提示冲突，不自动覆盖。接口不自动保存，不调整评分/排名或可见范围。
+真实模型外发仅本节最少字段；项目名应公开或脱敏，不传个人联系方式、凭据或商业秘密。供应商留存/训练规则待负责人核实，默认关闭；本地候选不等于生产合规放行。与本仓库合并后静态契约226 paths/276 operations。验证、未完成项以AI-003交付记录为准。

 ## 工作经历 AI 优化（AI-001，本地整合候选，2026-10-23）

 2026-10-26 告知候选更新：新增学生只读 `GET /profile/me/work-experience-optimization/notice`，优化 POST 必须带原生布尔 true 的 `externalProcessingConsent` 和当前 `consentNoticeVersion`。缺失/旧版本或字符串 true 拒绝；旧调用需同步接入。契约现为 213 paths / 261 operations；下文旧计数和缺版本示例为历史。详细流程及应用日志保护边界见 [告知与本次同意对接说明](ai-work-experience-consent-frontend-20261026.md)。本批未部署，仍默认 off、仅开发合成资料，不构成生产合规放行。
