+# 采购服务
+
+启动前必须显式设置下列环境变量；服务不提供默认管理员账号、密码或会话密钥。
+
+| 变量 | 要求 |
+| --- | --- |
+| `CMBUYER_ADMIN_USERNAME` | 非空管理员账号。 |
+| `CMBUYER_ADMIN_PASSWORD_BCRYPT` | 非空 bcrypt 密码哈希，不接受明文密码。 |
+| `CMBUYER_SESSION_SECRET` | 至少 32 字节的会话签名密钥。 |
+| `CMBUYER_COOKIE_SECURE` | 可选；存在时只能精确为 `true` 或 `false`。HTTPS 部署应设为 `true`。 |
+| `CMBUYER_DATABASE_SOURCE` | 已迁移 SQLite 的显式 data source。 |
+
+示例仅展示变量名，不提供可运行凭据：
+
+```powershell
+$env:CMBUYER_ADMIN_USERNAME = '<管理员账号>'
+$env:CMBUYER_ADMIN_PASSWORD_BCRYPT = '<bcrypt 密码哈希>'
+$env:CMBUYER_SESSION_SECRET = '<至少 32 字节的随机密钥>'
+$env:CMBUYER_COOKIE_SECURE = 'true'
+$env:CMBUYER_DATABASE_SOURCE = '<SQLite data source>'
+go run ./cmd/migrate -database $env:CMBUYER_DATABASE_SOURCE up
+go run ./cmd/server
+```
+
+采购服务会话仅保存在当前进程内；进程重启后既有登录会话会安全失效。

+## 问题 / 背景
+
+客户要求加快 MVP。现有全局门禁把全部 Phase 2 页面都冻结到 T-103 完成，范围过宽；管理员登录与只创建 DRAFT 的基础建单不读取真机页面字段，也不会启动试选或触发下单。
+
+## 方案
+
+1. 把门禁收窄为：T-103 前允许 T-201 管理会话与 T-202 DRAFT 建单/基础列表；T-203 的批量开始试选、T-204 试选证据详情和 T-205 以后继续冻结。
+2. 同步 AI 入口、编码规则和路线图；不修改 T-103 安全边界，不放宽不付款、第一趟禁下单、真机判据先取证或隐私证据分层。
+3. 并行启动 admin T-201；共享文档由本任务所有者统一修改。
+
+## 验收要点
+
+- 门禁文字不存在“冻结全部 Phase 2”的歧义。
+- T-201/T-202 不得出现 PDD 页面判据、试选结果、证据、授权、提交或支付能力。
+- 上下文校验、Vikunja 导出检查与 diff-check 通过。

+## 问题 / 背景
+
+T-102 已证明 canonical 链接可进入目标商品。T-103 随后在 PKG110 / Android 16 / 拼多多 8.17.0、衣服商品 goods_id `937122477375` 上确认：规格面板只能从详情页右下角精确文案“快要抢光”进入，面板固定显示收货区域和掩码手机号。T-110 经项目所有者批准，将该已取证点击定义为可逆、能力受限的规格面板导航；这不是通用购买入口豁免，不授权其他文案、数量、确认页、提交订单或支付。 项目所有者随后确认，面板刚打开时已自动选中目标颜色“黑色CHA(纯棉)”和尺码“M(建议100-115)”；因此本任务不再假设存在“未选择”或“只选择一个维度”的初始状态。
+
+## 关联需求与交互
+
+- 功能：F-006 第一趟试选；覆盖自动脱敏、`open_trial_sku_panel()`、`select_sku_options()`、`read_sku_unit_price()` 的真机 spike。
+- 用户故事：US-003、US-004、US-008；本任务无生产 GUI。
+- 架构 / API：`docs/04-architecture.md` 第三、四、5.4、六节；`docs/api.md` 证据上传和 `TrialSkuFlow`；T-104、T-105 与 Phase 2 的前置。
+
+## 方案
+
+1. 先实现本机确定性脱敏器，不先写页面判据。原始 screenshot/XML 只保存到 `%LOCALAPPDATA%\cmbuyer\artifacts\T-103\...\raw`，只允许脱敏器消费；agent、fixture、业务、日志、HTTP sink、Vikunja 与 Git 均不得读取/上传原始内容。
+2. 脱敏器绑定 PKG110 分辨率、拼多多 8.17.0、goods_id、人工声明状态和本项目证据配置，同时从 screenshot/XML 移除收货区域、地址与手机号内容，在 sibling `derived` 目录原子发布派生物。派生 XML 仍命中手机号模式、隐私区域无法确认、结构/分辨率/版本失配、哈希不一致或目标目录存在时 fail closed，不发布半成品。服务端只接收派生截图哈希和 sanitizer 版本，不接收原始文件/哈希/路径/XML。
+3. 由人运行脱敏器并本地确认派生 screenshot/XML 的三种真实状态：panel-opened-target-preselected（刚打开且目标规格已自动选中）、alternate-all-dimensions-selected（人工把颜色和尺码都改成非目标值）、target-selection-restored（再把两个维度恢复为目标值）。主 agent 只在派生 manifest、每态实际选中值与人工确认齐全后读取派生证据，提取最小 fixture。首轮旧证据不得复用为 fixture。
+4. 实现 `TrialSkuFlow` 窄 capability。`open_trial_sku_panel()` 只允许拼多多 8.17.0、goods_id `937122477375` 上证据绑定、精确唯一的 `快要抢光`；缺失、重复、版本失配或打开后面板判据不唯一时零后续点击。`免拼购买 / 单独购买 / 直接拼成` 等其他文案必须分别取证，不能包含、前缀、同义、OCR 或坐标兜底。
+5. 第一趟 capability 只含打开商品、受控打开面板、在维度容器内精确选择、读面板单价、脱敏取证和返回。接口不得暴露通用 `click`、`set_quantity()`、`go_to_order_confirm()`、`submit_order()` 或支付能力；规格面板中的“提交订单”、微信支付、先用后付和 0 元下单只作为硬拒绝判据，静态调用链测试证明不可达。
+6. 在脱敏派生 XML 上按维度容器隔离候选，文本等值匹配并读回选中态；缺失、重复、禁用、维度不明或选中态不唯一均停止。纯函数测试覆盖 `红`/`粉红`、`1`/`10` 等前缀碰撞。
+7. 单价只从规格面板证据确定的唯一节点读取，以十进制字符串返回，禁止浮点。记录真实文本是否含优惠前缀、货币符号是否拆节点、是否并列原价/区间价；语义不唯一、节点缺失、候选冲突或只能从详情页读取时返回 unreadable。
+8. 人最终在真机先把两个维度改成一组明确记录的非目标值，再执行受控入口、精确选择和读价脚本恢复目标规格，确认实际选择颜色分类=黑色 CHA（纯棉）、尺码=M（建议100-115）（以派生 XML 精确文本为准）、面板单价语义、派生证据隐私与退出行为；agent 保持 DOING 直到人工验收。
+
+## 验收要点
+
+- 三组原始证据分别对应 panel-opened-target-preselected、alternate-all-dimensions-selected、target-selection-restored，且仅在本机 raw 目录；脱敏器离线测试覆盖地址/手机号移除、截图与 XML 同步处理、状态/版本/分辨率/结构失配、手机号残留、原子性、异常脱敏和已有目录不覆盖。
+- 派生 manifest 记录 source/derived 本机哈希、sanitizer 版本、设备/App/goods_id/人工状态；原始页面正文、serial、地址和手机号不进入 manifest、日志、错误或上传。
+- 只从人工验收通过的派生证据编写页面判据与最小 fixture；判据绑定拼多多 8.17.0 和证据哈希。
+- `快要抢光` 精确唯一时才打开面板；其他文案、入口缺失/重复、面板不唯一、规格缺失/碰撞/禁用、价格不唯一均 fail closed。
+- 静态 API/导入测试证明 T-103 第一趟无通用点击、数量、确认页、提交订单或支付能力，“提交订单”及资金控件不可达。
+- 从规格面板可靠读取选中 SKU 单价为十进制字符串；无法唯一解释优惠价/原价/区间价时返回 unreadable。
+- client 全部单测、compileall、wheel metadata、上下文校验、完整 `init.ps1` 与 diff-check 通过。
+- `needs_device=true`：只有人完成受控入口、精确选择、单价读取、派生证据对应性/隐私和安全退出验收后才能 DONE。

+## 问题 / 背景
+
+T-103 在 PKG110 / Android 16 / 拼多多 8.17.0 真机确认：衣服商品 goods_id `937122477375` 的规格面板只能从详情页右下角“快要抢光”等购买语义按钮进入，不存在原架构假设的独立“规格 / 已选”入口。与此同时，规格面板固定展示收货区域与掩码手机号。项目所有者已批准调整第一趟入口边界，但“不付款、第一趟不可达提交订单、价格只从规格面板读取、敏感信息不进入业务数据/日志/上传/Git”等边界不变。
+
+## 关联需求与交互
+
+- 功能：F-006 第一趟试选；为 T-103 解阻，不实现页面选择器或真机点击代码。
+- 架构：`docs/04-architecture.md` 第一趟流程、安全边界、证据分层；`docs/05-coding-rules.md` 不可逆动作和敏感信息纪律。
+- API：设备试选证据只允许上传脱敏派生物；原始截图/XML 仅留采购工具本机隔离目录。
+
+## 方案
+
+1. 把“独立规格入口”改为“受控规格面板入口”：第一趟只可点击本项目真机证据证明、与拼多多版本绑定的唯一精确入口；当前仅确认 `快要抢光`。其他文案即使语义相近也不得推断复用，必须重新取证。
+2. 将点击入口与下单能力隔离。第一趟 capability 只允许打开受控面板、在维度内精确选择、读规格面板单价、生成脱敏证据和返回商品页；接口不得出现设置数量、进入确认页、提交订单、支付或通用任意点击能力。静态调用链和测试必须证明这些能力不可达。
+3. 规格面板内的“提交订单”以及微信支付、先用后付、0 元下单等控件全部列入硬拒绝区。入口缺失/重复、版本失配、打开后不是已取证面板、选择或价格不唯一时立即返回，不尝试相近按钮。
+4. 接受 PDD 页面会显示收货区域与掩码手机号这一事实，但不允许业务系统提取或传播。原始 screenshot/XML 仅写入 `%LOCALAPPDATA%` 隔离目录，不打印页面正文、不上传、不提交 Git；本地确定性脱敏器生成派生 screenshot/XML 和哈希，开发、fixture、服务端证据只消费派生物。
+5. 脱敏必须 fail closed：无法确认地址/手机号区域已移除、派生 XML 仍命中手机号模式、分辨率/结构不符合已取证版本，均拒绝发布派生证据。不得依赖人工口头“无需处理”绕过自动检查。
+6. 同步需求、架构、技术栈、编码规则、API、current-state 与 T-103。T-110 完成后把 T-103 依赖补为 T-110 并重新转 DOING；真正的脱敏器、入口判据和真机实现仍由 T-103 完成。
+
+## 验收要点
+
+- 文档明确区分“可逆的受控规格面板入口”与“不可逆的提交订单动作”，不把购买文案泛化为通用可点击入口。
+- 第一趟的 capability 列表与硬拒绝列表完整；提交订单、数量、确认页、付款和任意点击能力不可达。
+- 原始证据与脱敏派生证据的目录、生命周期、消费者和 fail-closed 条件清楚；服务端和 Git 永不接收原始隐私证据。
+- `docs/tasks/T-103.md` 在 T-110 完成后恢复 DOING，并要求先产出自动脱敏证据再写页面判据。
+- `python scripts/validate_agent_context.py`、Vikunja 导出检查与 `git diff --check` 通过。

+- 第一趟只批准证据/版本绑定、精确唯一的 `快要抢光`；其他购买文案不泛化。`TrialSkuFlow` 不暴露通用点击、数量、确认页、提交订单或支付能力。
+- 原始 screenshot/XML 只留本机隔离目录；服务端只接收自动复检通过的派生截图哈希与 sanitizer 版本，不接收原始文件、哈希、路径或 XML。
+- Phase 1 已拆分第一趟规格 spike 与第二趟数量/确认页 spike；T-103 已增加 T-110 依赖并按新边界恢复 DOING。
+- `validate_agent_context.py` 与 `git diff --check` 通过；本任务没有实现或运行任何真机点击代码。

+<!-- END VIKUNJA EXPORT -->
+
+## 边界
+
+- 本任务只调整架构、需求、API、编码规则与后续任务契约，不实现或运行任何真机点击代码。
+- 仍然绝不点击支付、免密支付、先用后付、0 元下单或扣款控件；不创建订单，不进入订单确认页。
+- 第一趟只允许未来实现点击**本项目真机证据证明、与拼多多版本绑定、精确唯一**的规格面板入口；
+  当前只确认 goods_id `937122477375`、拼多多 `8.17.0` 上的“快要抢光”。不得把人工经验中的
+  “免拼购买 / 单独购买 / 直接拼成”等文案直接加入白名单，分别取证前一律拒绝。
+- 第一趟 capability 不得包含通用 `click`、数量调整、订单确认、提交订单或付款能力；规格面板中的
+  “提交订单”及任何支付提示始终属于硬拒绝区，静态调用链必须保持不可达。
+- 接受原始规格面板证据在手机本地可能包含收货区域和掩码手机号，但不得从中提取业务字段、打印、
+  上传或提交 Git。只有确定性脱敏并通过自动检查的派生 screenshot/XML 才能供 agent、fixture、
+  采购服务或人工远程评审使用；脱敏不确定即 fail closed。
+- 价格仍只允许从规格面板和订单确认页读取，使用十进制字符串；不得用详情页价格补齐。
+- 本任务不得把 T-103 标为 `DONE`。文档边界完成并获得本次用户明确授权后，只能把 T-103 重新置为
+  `DOING`，由 T-103 继续实现脱敏器、判据、离线测试和人工真机验收。

+## 问题 / 背景
+
+T-201 已提供管理员会话；T-004 已提供 tasks 表。根据 T-010 加速门禁，T-103 尚未完成时只允许实现不启动试选的 DRAFT 手工建单与基础列表。
+
+## 关联需求与交互
+
+F-001、US-001、IX-002；GET /tasks、GET /tasks/new、POST /tasks；沿用已确认的传统表格与创建弹窗/直达页。
+
+## 方案
+
+1. 显式数据库配置并打开已迁移 SQLite；以仓储接口隔离 HTTP 和 SQL，创建事务只写 MANUAL、DRAFT、version=1。
+2. 表单校验任务名称、canonical 拼多多链接、颜色分类、尺码、正整数数量和正十进制总额上限；金额只用字符串并规范为两位小数。链接只接受 HTTPS mobile.yangkeduo.com/goods.html 且 goods_id 为唯一纯数字参数，额外查询参数不进入数据库。
+3. 以服务端生成的 create_key 同时作为任务 ID；重复相同 key 和相同内容返回原结果，不创建第二条，内容不同则冲突。
+4. GET /tasks 默认 created_at DESC 显示 DRAFT 基础表格；创建入口用服务端渲染的 modal 状态，/tasks/new 复用同一表单作为无脚本兜底；失败保留非密码输入并显示字段错误，成功 303 回列表且新任务第一行。
+5. 页面只显示需求字段、采购结果占位、DRAFT 状态与创建时间；不读取或伪造规格面板价格/证据，不提供勾选开始试选、状态推进、详情或设备接口。
+
+## 验收要点
+
+- 覆盖创建成功、倒序第一行、严格链接/goods_id、数量、金额、空白/长度、CSRF/未登录、幂等重放与冲突、SQL 错误 fail closed。
+- 弹窗与 /tasks/new 共享校验；错误保留输入并可访问；标题只链接到由 goods_id 重建的 canonical PDD URL并使用安全新标签属性。
+- go test ./...、go test -race ./...、go vet ./...、go build ./...、完整 init.ps1、上下文校验和 diff-check 通过。
+
+## 执行记录
+
+### 2026-08-04T08:30:47Z · ila
+
+已完成：DRAFT 手工建单与基础列表；已验证链接、金额、CSRF、幂等、SQLite 并发和 SSR 无障碍，Go 与上下文门禁均通过。
+<!-- END VIKUNJA EXPORT -->
+
+## 边界
+
+- 本任务只创建 `source=MANUAL`、`status=DRAFT`、`version=1` 的任务并显示 DRAFT 基础列表；不得
+  实现勾选、批量开始试选、`DRAFT → PENDING` 或任何其他状态流转，也不得新增设备领取接口。
+- 不增加或修改数据库 schema，不读写 `spec_trials`、`order_authorizations`、`order_submissions`，
+  不生成或展示机器实际规格、规格面板单价、截图、证据哈希或 PDD 页面判据。
+- 启动服务必须从显式 `CMBUYER_DATABASE_SOURCE` 读取 SQLite data source；缺失时明确失败，不提供
+  隐式内存库或仓库内默认数据库。服务不自动猜迁移目录；README 必须先给出显式迁移命令。
+- 商品链接只接受 `https://mobile.yangkeduo.com/goods.html`，且必须恰有一个纯数字 `goods_id`；
+  拒绝 userinfo、端口、fragment、重复参数、其他 host/scheme/path 和编码绕过。数据库只保存 goods_id，
+  展示链接由 goods_id 重建 canonical URL；`uin` 等额外查询参数既不保存也不回显。
+- 标题、颜色分类、尺码必须去除首尾空白后非空并受明确长度上限约束；数量必须是可表示的正整数；
+  总额上限必须是大于零、最多两位小数的十进制字符串并规范为两位小数。金额校验、保存与展示均不得
+  使用浮点数或从其他数字推测。
+- `create_key` 由服务端用 `crypto/rand` 生成并验证格式，同时作为任务 ID；相同 key 与相同规范化内容
+  重放只能返回原任务，不得二次 INSERT，相同 key 携带不同内容必须冲突。SQL 必须参数化，创建失败
+  不得留下半条或未知状态记录。
+- `GET /tasks`、`GET /tasks/new`、`POST /tasks` 都必须复用 T-201 管理会话；POST 必须验证 CSRF。
+  校验失败保留非敏感输入并逐字段提示，数据库内部错误只给通用响应，不泄露 SQL、路径或凭据。
+- 页面只使用服务端模板转义；标题商品链接在新标签打开时必须带 `noopener noreferrer`。导入按钮只作
+  禁用占位；不得加载外部资源或把原型假数据、真机数据、地址、手机号带进生产页面。
+- 不实现或引用试选、数量设置、订单确认、提交围栏、提交订单、付款、免密支付或先用后付能力。
