 ## 执行记录
 
-（完成后记录 mock、只读实跑与 tab 清理结果。）
+- 2026-07-11：完成 AI工场商品项目入口与原主图 URL 只读拉取代码。
+  - `app/editor.py` 新增 `read_product_image_urls()`，复用已验证 itembox rects 顺序返回 `{index, src}`；新增 `close_readonly_product()` 复用①采集 tab 清理规则。
+  - `app/image_studio.py` 新增项目入口 `pull_remote_main_image_urls()`：按账号+商品创建/打开项目，复用/启动账号 Chrome，只检测登录；明确登录页阻断，不确定登录继续尝试打开商品页；商品页用 `open_product(..., bring_to_front=False)` 后台只读打开，读取 URL 后同步为 remote-only `original` assets，不下载图片、不修改蝦皮、不点击更新。
+  - 原图 URL 刷新走 `sync_original_asset_urls()`：相同 URL 复用原 asset 并更新顺序，不再出现的 URL 标记 `missing`，不物理删除历史记录。
+  - `docs/04-architecture.md` 已补充 AI工场原主图读取的 CDP 约束。
+  - 测试覆盖：已开 Chrome 复用、未开 Chrome 启动、明确未登录阻断、`NO_SESSION_COOKIE` 不确定登录继续、商品失效 toast 文案上浮、成功读取 1..9 张 URL、重复刷新幂等、自动新建/复用 tab 清理接口，以及成功路径不调用标题修改/封面替换/点击更新。
+  - 验证：在只套用 T-587 diff 的 clean worktree 中运行 `python -m ruff check app tests main.py`、`py -3.10 -m compileall app main.py`、`py -3.10 -m unittest discover -s tests`（350 tests）和 `git diff --check`，全部通过。
+  - 真实蝦皮只读实跑未执行：本轮未指定可用的已登录测试账号别名；为避免擅自打开真实浏览器，只做 mock/CDP 合约验证，后续接 GUI 前可用测试账号对 ITEM_ID 51100639510 做一次只读确认。
