+### T-101 设备基线取证（2026-08-04 已完成人工双通道验收）
+
+`client/scripts/capture_device_baseline.py` 只允许对**手工明确填写**的 ADB serial 做连接前核验、
+设备型号 / Android / 拼多多版本读取、截图和 `dump_hierarchy(compressed=False)`。它不打开商品、
+不读取页面判据，也不执行采购、下单或付款动作。多个在线通道必须完成 `getprop` 物理身份比对：
+同一手机 USB + WiFi 同时在线，或任一在线通道的身份读取失败，都会 fail closed，不能随机继续。
+
+人工验收前，先由人把手机切换到不含收货地址、手机号、支付信息或其他无关隐私的安全页面，再在
+`adb devices -l` 中**手工复制**一个在线 serial；USB 和 WiFi 分别验收，且每次只保留一个通道在线。
+WiFi 通道必须由人先行建立；脚本禁止 `adb connect`、`adb disconnect` 或自动重连。以下命令中的尖括号
+必须替换为该次人工确认的实际 serial，不能省略或改成自动选择：
+
+```powershell
+# 仓库根目录；先手工确认设备状态，命令本身只读 ADB 清单
+D:\Portable\adb\adb.exe devices -l
+
+# USB：粘贴该次 devices -l 显示的 USB serial
+.\client\.venv\Scripts\python.exe client\scripts\capture_device_baseline.py --serial <USB_SERIAL> --output-dir "$env:LOCALAPPDATA\cmbuyer\artifacts\T-101\usb-baseline" --timeout 10 --adb D:\Portable\adb\adb.exe
+
+# WiFi：由人先建立 WiFi ADB 通道、断开 USB 后，粘贴该次 devices -l 显示的 WiFi serial
+.\client\.venv\Scripts\python.exe client\scripts\capture_device_baseline.py --serial <WIFI_SERIAL> --output-dir "$env:LOCALAPPDATA\cmbuyer\artifacts\T-101\wifi-baseline" --timeout 10 --adb D:\Portable\adb\adb.exe
+```
+
+成功时输出目录仅包含截图、完整 XML 与不含页面正文的 `manifest.json`（设备元数据、通道、时间、
+文件 SHA-256 和 serial 哈希）。`--timeout` 约束 ADB 命令、ADB socket 及 `takeScreenshot` /
+`dumpWindowHierarchy(compressed=False, max_depth=50)` 的公开 JSON-RPC 调用；uiautomator2 初始化仍有
+上游固定启动上限。截图 Base64 仅兼容 RPC 返回值中的空格、TAB、CR、LF，其余字符
+仍严格拒绝。XML 仅留在本机明确指定的证据目录；人工必须先在本地检查截图/XML，再只记录路径
+和哈希，不得把原始证据提交 Git。USB 与 WiFi 已分别由人完成取证和隐私检查，设备型号、Android、
+拼多多版本、产物路径及 SHA-256 已记录到 T-101；上述命令保留用于可审计的复现与排障。
+
+### T-102 按链接打开商品取证（2026-08-04 已完成人工真机验收）
+
+`client/scripts/capture_product_open.py` 只接受
+`https://mobile.yangkeduo.com/goods.html?goods_id=<纯数字>` 的唯一 canonical 表示。解析后由
+`goods_id` 再次重建 URL，并以参数数组执行显式限定 `com.xunmeng.pinduoduo` 的 Android `VIEW`
+intent；没有任意 URL、任意 shell 或其他 App 控件操作入口。运行拼多多版本必须精确等于 T-101 已
+取证的 `8.17.0`，版本失配会在 intent 前停止。
+
+```powershell
+# 仓库根目录；USB 或 WiFi 每次只保留一个通道在线，再手工复制该次 serial
+D:\Portable\adb\adb.exe devices -l
+.\client\.venv\Scripts\python.exe client\scripts\capture_product_open.py --serial <SERIAL> --url "https://mobile.yangkeduo.com/goods.html?goods_id=<GOODS_ID>" --output-dir "$env:LOCALAPPDATA\cmbuyer\artifacts\T-102\product-open-<GOODS_ID>" --timeout 10 --adb D:\Portable\adb\adb.exe
+```
+
+脚本在 intent 成功后，以 `--timeout` 为明确上限只读轮询前台 package；只有观察到拼多多才采集截图与
+完整 XML，超时仍 fail closed。这一等待只解决 App 异步切换，不根据 Activity、节点文本或旧项目常量
+声称已到详情页。成功目录以原子方式发布，manifest 仅记录 `goods_id`、canonical URL、
+设备/App 非敏感元数据、受限命令摘要、文件路径和 SHA-256，不含原始 serial、Activity 或页面正文。
+必须由人本地确认截图对应目标商品并检查截图/XML 无地址、手机号、支付信息或其他无关隐私；原始
+证据不得提交 Git。T-102 已由人确认 goods_id `958756616606` 对应目标商品并完成截图/XML 隐私检查，
+设备、版本、证据路径与 SHA-256 已记录到任务执行记录。
+
+Windows 的标准入口是仓库根 `./init.ps1`。它要求 Go、两端目录及其哨兵文件存在；已有合规
+`client/.venv` 时，所有采购工具检查与 validator 都使用该解释器。只有 venv 不存在时，才从 `py -0p`
+枚举的版本中确定性选择最高的 Python 3.11+ 创建它；没有合规版本时明确失败，绝不回退默认 `python`。
+它执行 admin 的 `go mod download` / test / vet / build、client 的 editable install / 包导入 / unittest /
+compileall。既有 `client/.venv` 若不是 Python 3.11+ 会明确失败，不会自动覆盖用户环境。`init.sh` 保持等价门禁语义；WSL 或 Unix 环境缺少所需 Go、Python 3.11+
+或项目文件时必须非零退出，语法通过或 Unix 成功不构成 Windows / 真机验收。
+
+采购工具的运行时依赖只维护在 `client/requirements.txt`。`client/pyproject.toml` 通过 setuptools
+动态读取该文件生成 wheel 的 `Requires-Dist`，避免两份依赖列表漂移；
+`scripts/verify_wheel_metadata.py` 会验证生成 wheel 已声明全部这些依赖。
+
+当前 Windows 默认 `python` 仍可能指向 Python 3.10，不满足采购工具的 Python 3.11+ 下限；
+不得把未加版本选择器的 `python` 当作采购工具命令。统一入口优先使用既有合规 venv，仅在需要创建时
+自动选择 Launcher 中最高的合规版本；本机 Python 3.12 与 3.14 均已验证，主工作区当前选择 Python
+3.14。桌面 GUI 与真机流程不属于 T-003 验收范围。

+
+```powershell
+# 在仓库根执行统一初始化；成功后再进入 client/
+.\init.ps1
+cd client
+.\.venv\Scripts\python.exe -m cmbuyer_client
+```
+
+`client/requirements.txt` 是唯一依赖来源，`client/pyproject.toml` 动态读取它生成 wheel 的
+`Requires-Dist`。Python 3.12 与 3.14 均已验证离线测试、编译与 wheel 元数据；完整运行时依赖安装
+（`pip install -e .`）已通过。`init.ps1` 优先使用合规既有 venv，缺失时自动选择最高的 Python 3.11+；
+本机 Python 3.12 与 3.14 均已验证，主工作区当前选择 Python 3.14。桌面 GUI 与真机流程未作为 T-003
+验收执行。
+
+T-101 的人工真机验收命令（先把手机切到不含收货地址、手机号、支付信息或其他无关隐私的安全页面；
+必须从 `adb devices -l` 手工复制在线 serial，不能留空或自动选择）：
+
+```powershell
+# 仓库根目录；USB 和 WiFi 分开执行，每次只保留一个通道在线
+D:\Portable\adb\adb.exe devices -l
+.\client\.venv\Scripts\python.exe client\scripts\capture_device_baseline.py --serial <USB_SERIAL> --output-dir "$env:LOCALAPPDATA\cmbuyer\artifacts\T-101\usb-baseline" --timeout 10 --adb D:\Portable\adb\adb.exe
+# WiFi 必须由人先建立通道、断开 USB 后再手工粘贴在线 WiFi serial；脚本不自动 connect/reconnect
+.\client\.venv\Scripts\python.exe client\scripts\capture_device_baseline.py --serial <WIFI_SERIAL> --output-dir "$env:LOCALAPPDATA\cmbuyer\artifacts\T-101\wifi-baseline" --timeout 10 --adb D:\Portable\adb\adb.exe
+```
+
+脚本只读取非敏感设备元数据、拼多多版本、截图和完整 XML；不会打开商品或写页面判据。它对同机双
+通道、身份读取失败、offline、unauthorized、超时或 serial 不存在均 fail closed。成功目录的
+`manifest.json` 只记录元数据、产物路径和 SHA-256，不记录 XML 页面正文或原始 serial。T-101 已由人
+完成两次验收并确认原始证据不含敏感信息；`--timeout` 约束 ADB 命令、ADB socket 以及截图/节点树的
+公开 JSON-RPC 调用，uiautomator2 初始化仍有上游固定启动上限。截图/XML 只保留在本地，执行记录只写
+路径和 SHA-256，原始证据不得提交 Git。
+
+T-102 的人工真机验收命令（只接受唯一 canonical 链接；USB 或 WiFi 每次只保留一个通道在线）：
+
+```powershell
+# 仓库根目录；从输出中手工复制本次在线 serial
+D:\Portable\adb\adb.exe devices -l
+.\client\.venv\Scripts\python.exe client\scripts\capture_product_open.py --serial <SERIAL> --url "https://mobile.yangkeduo.com/goods.html?goods_id=<GOODS_ID>" --output-dir "$env:LOCALAPPDATA\cmbuyer\artifacts\T-102\product-open-<GOODS_ID>" --timeout 10 --adb D:\Portable\adb\adb.exe
+```
+
+脚本只允许 Android `VIEW` intent，并把 package 固定为 `com.xunmeng.pinduoduo`；intent 后会在
+`--timeout` 的有限窗口内只读轮询前台 package，解决 App 异步切换造成的一次性误判，超时仍会停止。
+它不点击、滑动、输入或判断商品页节点，也不打开规格、读取价格、进入下单或支付。运行拼多多版本必须精确为
+`8.17.0`，否则在 intent 前停止。成功后由人本地查看截图/XML，确认页面确为该 `goods_id` 对应商品并
+检查无地址、手机号、支付信息或其他无关隐私；只回报 manifest 路径及截图/XML SHA-256，原始证据
+不得提交 Git。T-102 已由人确认 goods_id `958756616606` 的目标商品及截图/XML 隐私，并完成验收。

+## 问题 / 背景
+
+仓库尚无 admin/go.mod 和可运行的采购服务代码，init.ps1 因此按预期以退出码 3 停止。没有稳定的 Go 骨架、健康检查和真实验证命令，后续数据模型与服务端任务无法开始。
+
+## 关联需求与交互
+
+- 功能：Phase 0 工程地基，不新增业务功能。
+- 用户故事 / 交互：不适用，不实现生产页面。
+- 架构 / API：遵循 docs/03-tech-stack.md；只提供健康检查，不新增采购业务接口。
+
+## 方案
+
+1. 在 admin/ 初始化 Go 1.23+ 模块，采用既定 gin / SQLite 技术栈和可测试的应用入口。
+2. 提供健康检查端点及对应单元测试；启动时错误必须显式返回，不吞错。
+3. 建立后续可扩展但保持最小的目录结构，不提前实现登录、任务、授权、提交订单或支付逻辑。
+4. 运行 go test ./... 与 go vet ./...，并记录真实命令。
+5. T-001 作为本轮共享文档所有者，只更新 admin 相关的 docs/03-tech-stack.md、docs/00-ai-start-here.md、docs/current-state.md 段落；不得代写尚未验证的 client 命令。
+
+## 验收要点
+
+- admin/go.mod 存在，Go 模块与依赖可解析。
+- 健康检查端点可通过 httptest 验证状态码和稳定响应。
+- go test ./...、go vet ./... 在 admin/ 通过。
+- 共享文档中的 admin 占位命令替换为经实际运行的命令，client 未完成部分仍明确标为未初始化。
+- 不包含采购业务、真机页面判据、下单或付款代码。

+## 问题 / 背景
+
+仓库尚无 client/requirements.txt 和可运行的采购工具代码，init.ps1 因此按预期以退出码 3 停止。没有稳定的 Python 包、测试入口、日志与产物策略，后续 ADB/uiautomator2 真机取证无法开始。
+

+- 功能：Phase 0 工程地基，不实现采购执行流程。
+- 用户故事 / 交互：不适用，本任务只建立应用骨架，不实现已确认原型的生产界面。
+- 架构 / API：遵循 docs/03-tech-stack.md 与 TaskSource / ResultSink 边界；不新增跨端接口。
+
+## 方案
+
+1. 在 client/ 建立 Python 3.11+ 包、requirements.txt、应用入口和最小测试结构。
+2. 声明既定 PySide6 / uiautomator2 依赖，但基础单元测试不得要求连接真机。
+3. 建立日志和运行产物目录策略；本地虚拟环境与运行产物必须被 client 范围内的忽略规则排除，日志不得记录 token、地址、手机号或支付信息。
+4. 保证 python -m unittest discover -s tests -t . 与 python -m compileall -q src tests 可运行。
+5. T-001 关闭前不修改共享文档。先在 Vikunja 评论记录已验证的 client 命令；T-001 完成后由任务所有者先提交 write_paths 扩展，再更新共享文档并关闭 T-002。
+
+## 验收要点

+- unittest 与 compileall 在 client/ 通过，且不需要真机。
+- 日志 / 产物路径和脱敏边界有测试或可验证配置。
+- 不包含拼多多页面判据、真机自动化实现、下单或付款代码。

+## 问题 / 背景
+
+T-001 与 T-002 已建立两端可运行骨架，但仓库根 init.ps1 / init.sh 仍沿用占位命令：Windows 默认 Python 3.10 不满足 client 的 Python 3.11+ 下限，桌面端仍按 requirements.txt 安装而不是规范的 editable package，启动命令也指向不存在的 src/main.py。统一入口若不能主动验证工具链和两端基线，后续任务会在错误环境上叠加实现。
+
+## 关联需求与交互
+
+- 功能：Phase 0 工程地基，只建立开发安装、验证与启动提示。
+- 用户故事 / 交互：不改采购服务或采购工具产品界面。
+- 架构 / API：不改业务接口、数据模型或任何采购安全边界。
+
+## 方案
+
+1. 完善 init.ps1：显式选择并验证 Python 3.11+，创建或校验 client/.venv，以 editable 方式安装 client，再运行两端离线测试、静态检查和构建。
+2. 完善 init.sh 的等价流程与缺失工具提示；在无 Windows 工具链的 WSL 环境只允许明确失败，不得把跳过当成功。
+3. 两端目录、Go、Python、venv 或必要文件缺失时输出可操作原因并返回非零；任何门禁失败立即停止。
+4. 成功后只打印真实启动命令：采购服务 go run ./cmd/server；采购工具虚拟环境 Python -m cmbuyer_client。
+5. 同步入口、技术栈与当前状态文档；不修改 admin/client 业务代码。
+
+## 验收要点
+
+- Windows 一条命令完成两端安装、admin test/vet/build、client unittest/compileall 与上下文门禁。
+- 不会使用 Python 3.10 创建采购工具环境；已有低版本 venv 会明确失败并给出修复提示。
+- editable install 与启动模块和 T-002 已验证契约一致。
+- init.sh 至少通过 bash 语法检查，且与 PowerShell 入口保持同一边界。
+- 不连接真机，不实现采购、下单或付款逻辑。

+## 问题 / 背景
+
+T-001 已建立可运行的采购服务骨架，但尚无业务实体、数据库 schema 或可验证的状态机。后续登录、建单、领取、授权和提交围栏都依赖一致的数据模型；若先写 HTTP 页面再补状态约束，会把资金安全边界分散到处理器中。

+- 功能：Phase 0 核心数据模型地基。
+- 用户故事 / 交互：不适用，不实现生产页面。
+- 架构 / API：以 docs/04-architecture.md 第四、第五节和 docs/api.md 为权威；schema 变化必须同步两者。
+
+## 方案
+
+1. 从现有架构/API逐字段提取 tasks、order_authorizations、order_submissions，不臆造接口字段。
+2. 使用 goose 与 SQLite 建立可重复迁移及约束；金额只存十进制字符串，禁止 float。
+3. 在 admin/internal/domain 建立显式状态与合法转换，非法转换 fail closed，并用表驱动测试覆盖。
+4. 对一次性授权、提交围栏和不可重试结果只建立数据约束与纯状态规则，不实现 HTTP、真机点击或下单函数。
+5. T-002 为 DOING 时不修改 docs/current-state.md；代码与架构/API完成后先记录验证，待 T-002 关闭再扩展 write_paths 并收口状态快照。
+
+## 验收要点
+
+- tasks、order_authorizations、order_submissions 表和约束与架构文档一致，迁移可重复向上/向下验证。
+- 核心状态合法/非法流转有单元测试；第一趟状态路径不引用任何下单函数。
+- 金额字段是十进制字符串，代码和 schema 不使用浮点数。

+## 问题 / 背景
+
+T-002 已建立采购工具骨架，但本项目还没有对实际 Android 手机、ADB 通道或 uiautomator2 做过取证。后续所有拼多多页面判据都依赖稳定、显式且可审计的设备连接；若复用前序项目结论或自动猜设备，会把错误设备和旧页面事实带入生产流程。
+
+## 关联需求与交互
+
+- 功能：Phase 1 真机环境盘点，是 T-102/T-103 的前置。
+- 用户故事 / 交互：采购工具配置页的显式设备 serial、连接检查与错误反馈。
+- 架构 / API：只验证 ADB/uiautomator2 基础能力，不编写拼多多页面判据，不调用采购服务业务接口。
+
+## 方案
+
+1. 实现显式 serial 的设备连接边界与可替换命令执行器；禁止留空自动选择，离线测试覆盖无设备、多设备、unauthorized/offline 和同一手机 USB+WiFi 双通道冲突。
+2. 提供只读取证命令：对指定通道连接 uiautomator2，获取设备型号/Android 版本/拼多多 App 版本，执行截图与 dump_hierarchy(compressed=False)，所有超时可配置。
+3. 产物按稳定目录保存并记录 SHA-256；日志只记录设备标识与元数据，不记录 token、地址、手机号或页面全文。
+4. 先完成 mock/fixture 离线测试；随后由人分别用 USB 与 WiFi 真机执行并把设备、Android、拼多多版本、截图/XML 路径和结论写入任务执行记录。
+5. 同一手机两个通道同时在线必须明确拒绝，不能随机选一个继续。
+
+## 验收要点
+
+- USB 和 WiFi 均能显式指定并完成截图、compressed=False XML dump。
+- 设备未授权、离线、超时、serial 不存在和双通道冲突有可区分错误。
+- 取证记录含设备型号、Android 版本、拼多多 App 版本、通道、时间、截图/XML 路径及 SHA-256。

+## 问题 / 背景
+
+T-101 已证明同一台 PKG110（Android 16、拼多多 8.17.0）可通过 USB/WiFi 显式 serial 完成只读截图与完整 XML 取证。MVP 下一风险是任务自带的合法拼多多链接能否由 Android intent 打开到对应商品详情页。此前项目和旧文档不能证明当前 App 的行为；若先写详情页判据，会把未经本项目真机验证的假设带入 T-103。
+
+## 关联需求与交互
+
+- 功能：F-006 的第一步 `open_product(url)`；仅覆盖链接打开，不覆盖规格面板、规格选择或价格。
+- 用户故事 / 交互：采购工具执行链接任务前的只读真机 spike；无生产 GUI。

+1. 只接受 HTTPS canonical 链接 `https://mobile.yangkeduo.com/goods.html?goods_id=<纯数字>`；拒绝 userinfo、非默认端口、fragment、重复/缺失/非数字 goods_id、其他 host/path 和额外业务参数。解析后由代码按 goods_id 重建 canonical URL，绝不把任意输入拼入 shell。
+2. 复用 T-101 的显式 serial、同机多通道 fail-closed、no-reconnect、类型化超时和原子证据发布边界；运行拼多多版本必须精确等于本项目已取证的 8.17.0，否则在打开链接前停止。
+3. 通过参数数组执行只含 Android `VIEW` intent 语义的 `adb shell am start -W`，显式限定包 `com.xunmeng.pinduoduo`；不使用 shell 字符串、不点击/滑动/输入任何控件。Android 命令失败、超时、未解析 intent、未停留在拼多多包、截图/XML 失败分别给出脱敏错误。
+4. 启动后只读取 current app/package、截图和 `dumpWindowHierarchy(compressed=False)`，manifest 记录 goods_id、canonical URL、设备/App 元数据、命令结果摘要、路径与 SHA-256，不记录页面全文或原始 serial。原始截图/XML 仅存 `%LOCALAPPDATA%`，不提交 Git。
+5. 离线 mock 测试覆盖 URL 正反例、参数数组与超时、版本失配在 intent 前停止、包不匹配、无 UI 点击 API、证据原子性和异常脱敏。代码完成后由人使用一个明确 goods_id 在仅单通道在线的真机执行，人工确认截图确为对应商品详情页并检查 XML/截图无敏感信息；再把设备、Android、拼多多版本、goods_id、路径、SHA-256 与结论写入执行记录。
+
+## 验收要点
+
+- 合法 canonical 链接可在拼多多 8.17.0 上打开；人工确认到达与 goods_id 对应的商品详情页。
+- 非法链接、设备状态、App 版本失配、intent 失败/超时、落在非拼多多包、证据失败均有可区分且不泄露页面内容的错误。
+- 取证记录包含 PKG110、Android 16、连接方式、拼多多 8.17.0、goods_id、canonical URL、截图/XML 本地路径与 SHA-256。
+- client 全部单测、compileall、wheel metadata、上下文校验及完整 `init.ps1` 通过。
+- `needs_device=true`：agent 只能完成离线实现并保持 DOING；只有人完成真机链接打开、页面对应性与隐私检查后才能 DONE。

+
+2026-08-04：已认领 T-102，工作分支 `task/t-102-open-product`，从任务定义提交 `4281b06` 开始实现。离线阶段只实现严格 canonical URL 校验、Android VIEW intent、版本/设备 fail-closed 与原子证据采集；不写商品详情页节点判据，不操作任何 App 控件。`needs_device=true`，离线实现完成后仍保持 DOING，等待人工提供明确商品链接并完成真机页面对应性和隐私验收。

+
+2026-08-04：T-102 离线实现已由子 agent 完成并经主 agent 独立审查、两轮退回修正后通过，代码提交 `7040bb6`。实现包含：唯一 canonical 商品 URL 校验与重建、ADB 内层纯数字 goods_id 二次围栏、固定 package 的 Android VIEW intent、拼多多 8.17.0 intent 前版本围栏、前台 package 核验，以及截图/XML 原子取证与脱敏 manifest；无点击、滑动、输入、规格、价格、下单或支付能力，也未写商品详情页节点/Activity 判据。主审验证：43 项 client 离线测试、compileall、完整 init.ps1（含 admin test/vet/build）、wheel metadata、agent-context 与 diff-check 均通过；当前 wheel SHA-256 为 c675cd527849149ec25f213a0d67da31d0bb497cd8c5ed255d71154c103659ed（审计临时产物已清理）。未连接或操作真机，T-102 继续保持 DOING，等待人工使用明确 canonical 商品链接执行取证，并确认页面对应性与隐私。

+2026-08-04 人工真机首轮：使用 WiFi serial `192.168.0.173:5555` 与 canonical 商品链接 `https://mobile.yangkeduo.com/goods.html?goods_id=958756616606` 执行 T-102 脚本。脚本通过 URL/intent 前置围栏，但在 intent 后返回“商品链接打开后前台应用不是拼多多”，按 fail-closed 规则停止，未发布完整取证。人在 Chrome 中可打开该 URL，只能证明网页链接有效，不能证明拼多多 App 已接管。T-102 保持 DOING；下一步由人只读取当前前台 package，区分瞬时切换/检查过早与实际落到 Chrome、系统解析器或其他包，在得到事实前不移除 package 围栏、不增加页面判据或 UI 兜底。
+

+- 不引用或实现 `go_to_order_confirm()`、`submit_order()`、提交订单、付款、支付、授权或采购服务接口；
+  不把前序项目的 URL、activity、节点文本或页面结论当作事实。
+- 输入 URL 必须先严格解析并按纯数字 `goods_id` 重建，再以参数数组传给 ADB；禁止 shell 拼接、
+  任意 scheme/host/path、短链跳转、额外参数或自动猜测链接。
+- 运行拼多多版本与本项目已取证版本不一致时必须在 intent 前停止；证据失败、当前包不符或结果无法
+  由人确认时均不得声称成功，不增加自动点击或其他兜底路径。
+- 截图和完整 XML 只保存在明确的本地 T-102 目录，人工检查后只把路径、SHA-256 与非敏感元数据
+  写入执行记录；不得提交原始证据，不记录地址、手机号、支付信息或无关页面正文。
+- 不修改 `admin/`、业务 API、数据模型、生产 GUI 或 T-103 规格面板逻辑。
+- `needs_device: true`：agent 完成离线实现后保持 `DOING`；只有人使用明确 goods_id 完成真机打开、
