 **下一步**：
 - commit / push 到 Gitea main 後讀回 CD；deploy 後驗證 `/api/v1/agents/awoooi-priority-work-order-readback` 與 `/zh-TW/awooop/work-items` 顯示 55 個插入工作項與新增 spotlight。
 
-## 2026-07-02 — P0 reboot Windows99 management channel CD #4402 workbench contract 修正
+## 2026-07-02 — P0 reboot Windows99 management channel CD #4402/#4403 contract 修正
 
 **完成內容**：
 - Gitea public queue 讀回 `aaa617f00 fix(reboot): expose windows99 management channel readback` 的 `cd.yaml` run `#4402` 狀態為 `Failure`；production API 仍停在舊版，不能宣稱已部署。
 - 公開 tests log 定位失敗點：`apps/api/tests/test_delivery_closure_workbench_api.py::test_delivery_closure_workbench_endpoint_returns_product_summary` 仍硬期待舊 safe next step `collect_windows99_vmware_autostart_verify_readback_then_rerun_all_host_reboot_scorecard_no_secret_no_reboot`。
 - 已同步 delivery closure workbench 測試 contract 到新版 reboot scorecard truth：safe next step 改為 `restore_windows99_no_secret_management_channel_or_collect_local_console_verify_readback_then_rerun_reboot_scorecard_no_reboot`，active blockers 從 `13` 收斂到 `11`，readiness 從 `15` 升為 `43`，`product_data_green=true`，StockPlatform freshness / ingestion 為 `ok`，drill preflight blockers 從 `9` 收斂到 `5`。
 - 修正重點是測試與 readback contract 補齊，不是放寬 SLO；`windows99_remote_execution_channel_unavailable` 與 `windows99_vmware_autostart_readback_missing` 仍為 P0 blocker。
+- `#4403` 第二輪 CD 再定位到 `apps/api/tests/test_stockplatform_public_api_runtime_readback.py::test_stockplatform_public_api_runtime_readback_blocks_live_502`：現在 committed scorecard 已是 StockPlatform freshness / ingestion `ok`，因此模擬 live 502 時 `live_drift_from_committed_scorecard=true` 才是正確判讀；已修正測試，避免未來把 live 502 regression 誤判成 no drift。
