+## 问题 / 背景
+
+T-004 已把本机私有蝦皮文本和 JPEG 严格导入为 `ProbeTask`，T-101 已证明固定搜索词
+可以进入拼多多结果页，但业务工作流尚不能从标题、SKU、数量和参考图得到受约束的
+搜索需求。T-103 只验证结构化需求提取，不让模型控制页面、不评估候选，也不提交订单。
+
+## 关联需求与交互
+
+- 功能：F-004 结构化需求提取、F-007 安全失败。
+- 用户故事：US-004、US-006。
+- 交互：Android“探针”页提供独立的需求提取入口，展示脱敏状态、SKU、数量、置信度、
+  警告和是否需要人工复核。
+- 架构：`ProbeTask` -> 隐私映射 -> `RequirementExtractor` -> provider-neutral gateway
+  -> 严格 schema -> 确定性硬约束复核。
+
+## 方案
+
+1. 建立与供应商无关的需求提取输入、输出、错误码和 JSON schema。
+2. VLM 请求只保留标题、SKU 和参考图；数量留在本地，订单号、店铺名及本机路径不
+   进入 prompt。
+3. SKU、数量和预算只从原始任务产生；模型响应无权覆盖。当前 `ProbeTask` 没有预算，
+   输出固定为未知并产生警告。
+4. 严格校验图片大小、媒体类型和 SHA-256；严格解析模型 JSON，拒绝额外字段、坐标、
+   动作授权和格式不明输出。
+5. 置信度低于固定探针阈值或输出无效时进入人工复核，不扩大搜索或触发拼多多动作。
+6. 普通测试使用 Fake gateway；真实调用只通过用户已配置且声明支持需求提取的
+   OpenAI 兼容供应商进行，每次用户操作最多发出一次模型调用。
+
+## 验收要点
+
+- [x] 私有样本标题、SKU、数量和 JPEG 可形成不含订单号、店铺名的 VLM 请求。
+- [x] 有效模型响应可解析为版本化 schema。
+- [x] SKU 和数量与原始 `ProbeTask` 完全一致，模型不能改写。
+- [x] 未提供预算时不会由模型猜测，并产生结构化警告。
+- [x] 低置信度、冲突、无效 JSON、额外动作字段和图片校验失败均安全转人工或明确失败。
+- [x] API Key、原图 Base64、订单号、店铺名和模型原始响应不进入普通日志。
+- [x] Fake gateway 测试覆盖成功、隐私、硬约束、低置信度和错误路径。
+- [x] `lintDebug test assembleDebug` 通过，默认 APK 不含私有 fixture。
+- [x] 设备无真实测试凭证；已记录外部 blocker，并用一次性本机 mock 验证真实 Android
+  请求链路，不把 mock 结果当成模型效果证据。
+
+## 边界
+
+- 不让 VLM 输出或执行坐标、点击、状态迁移、下单或支付动作。
+- 不把候选截图交给模型；候选评估属于 T-104。
+- 不引入新的供应商 SDK；沿用现有 OpenAI 兼容客户端。
+- 不提交私有订单、图片、生成 fixture、API Key 或模型原始响应。
+- 不把技术探针的端上密钥路径当作正式架构；正式密钥仍由后端保管。
+
+## 执行记录
+
+### 2026-07-25：任务开始
+
+- 基于 T-102 提交 `c25d63c` 开始。
+- 已确认现有 `VLMClient` 可复用 OpenAI 兼容多模态调用，但业务层缺少 schema、隐私
+  映射、确定性复核和低置信度处理。
+- 当前外部 blocker 仍是供应商、模型、测试凭证、成本上限和数据留存未确认；先完成
+  provider-neutral 契约、Fake 测试和可配置真实探针，不使用默认付费调用。
+
+### 2026-07-25：实现
+
+- 新增 `RequirementExtractionInput/Result`、版本化最终 JSON、严格模型响应 parser 和
+  `RequirementExtractor`。模型只能返回搜索词、类目、带来源属性、置信度和警告；
+  额外字段、动作/坐标语义、格式或边界错误统一转人工。
+- 隐私映射只把标题、SKU 和参考图交给 gateway。订单号、店铺名、相对路径和数量不
+  进入 prompt；SKU、数量、空预算和图片 SHA-256 由确定性代码组装。
+- 固定探针阈值为 `0.75`；低于阈值以及图片歧义、标题/图片冲突或 SKU 不清晰均进入
+  人工复核，不触发拼多多动作。
+- 新增 `predictStructuredOnce`，每次按钮操作最多调用 provider 一次；禁用连接自动
+  重试和 HTTP/HTTPS 重定向，协程取消会取消底层 call，调用上限 75 秒。HTTP 错误不
+  读取响应正文，成功响应上限 64 KiB。
+- 远程端点只允许 HTTPS；无 API Key 的本机回环 HTTP 可用于受控 mock。标题和 SKU
+  分别限制为 2048、512 个 UTF-8 字节。JPEG 在调用前复核媒体类型、20 MiB 上限、
+  魔数、大小和 SHA-256，按声明长度精确读取，解码后最长边限制为 2048 px。
+- `ApiProvider` 增加 `supportsRequirementExtraction`；GUI-Owl 和 MAI-UI 明确禁用。
+  加密凭证存储不可用时需求探针 fail closed。
+- “采购验证探针”增加独立 VLM 入口和 IDLE/RUNNING/READY/MANUAL_REVIEW/FAILED/
+  STOPPED 状态；展示 schema 摘要，但不展示订单号、店铺名或图片路径。
+
+### 2026-07-25：自动化验证
+
+- `$env:ANDROID_HOME="$env:LOCALAPPDATA\Android\Sdk";`
+  `$env:ANDROID_SDK_ROOT=$env:ANDROID_HOME;`
+  `.\gradlew.bat lintDebug test assembleDebug --no-daemon` 成功。
+- App Debug/Release、task contract 和导入器共 20 份报告、122 次测试，0 failure、
+  0 error、0 skipped；默认 Debug APK 中 `assets/probe-fixtures/` 条目数为 0。
+- Fake gateway 覆盖有效 schema、订单/店铺/路径/数量不进入 prompt、单次调用、
+  原始 SKU/数量保持、空预算、0.75 阈值边界、冲突转人工、无效/动作字段、JPEG
+  魔数/哈希失败、输入长度、provider 失败、调用取消和安全端点策略。
+- 静态检查确认需求链路没有记录 prompt、图片字节或原始响应，也没有可执行动作输出。
+
+### 2026-07-25：真机集成 smoke
+
+- OnePlus PKG110、Android 16/API 36、肉包 `1.4.2 (7)` 上显式注入 T-004 私有
+  fixture；设备未配置真实 API Key，直接点击时稳定显示“未配置模型”且不发网络请求。
+- 为验证网络链路，临时选择自定义 provider，通过 `adb reverse` 连接一次性本机
+  OpenAI 兼容 mock。App 只发出 1 次 `/v1/chat/completions` POST，包含 1 张 JPEG
+  data URL；布尔审计确认 prompt 不含订单/店铺字段和数量键。
+- mock 返回的严格 schema 以 `0.82` 置信度进入 READY；UI 显示类目、属性、原始
+  SKU/数量、空预算和 `MAX_BUDGET_NOT_PROVIDED`。截图/XML 和 mock 布尔审计位于
+  被忽略的 `.local/`，请求正文和图片未落盘。
+- 最新 APK 再次 smoke 后，将 provider 恢复为无密钥的阿里云配置并重新触发；UI
+  显示“未配置模型”，此前 READY 的搜索词和类目不再存在，证明失败路径会清空旧结果。
+- smoke 后已移除 `adb reverse`、停止本机 listener 并恢复设备原 API provider。
+  logcat 未写入订单号、店铺名、标题、SKU、prompt、Base64 或原始响应。
+
+### 未验证范围
+
+- 没有可用的真实 VLM 测试凭证，因此未验证任何供应商的真实提取质量、时延和费用。
+- 真实供应商、模型、成本上限、数据留存地区和图片隐私规则仍是外部 blocker；启用
+  前必须由用户显式配置并确认，不得把本机 mock 结果计入 20 条业务试验。
+
+## 后续
+
+- T-104 读取 T-102 的受控候选证据和本任务的 `RequirementExtraction`，输出匹配项、
+  缺失项和拒绝原因，并停在人工确认点。
+- T-104 继续使用 Fake gateway 和本机 mock 验证集成；没有真实凭证时不能宣称候选
+  匹配质量已验证。
