+## 2026-06-30 — 09:28 P0 priority work-order runtime source truth 正規化
+
+**完成內容**：
+- 修正 `apps/api/src/services/awoooi_priority_work_order_readback.py`：當 Delivery Workbench 讀到合法 production runtime deploy SHA 時，將 `current_head` 與 `mainline_execution_state` 的 current main / CD / deployed source 欄位正規化為 `production_readback:<short_sha>`，不再讓舊 snapshot 的 `#3973`、`49637ee7` 或 `f426522` 混入目前主線進度。
+- 新增 `rollups` / `summary`，明確輸出 `production_source_truth_available`、`stale_current_head_metadata_normalized`、`stale_cd_runs_reopen_closed_work=false`、P0-006 fresh reboot event gate 與 P0-004 / reboot preflight readiness。
+- 補 `apps/api/tests/test_awoooi_priority_work_order_readback_api.py` regression：以 `AWOOOI_BUILD_COMMIT_SHA` / `AWOOOI_DESIRED_API_IMAGE_TAG` 模擬 production env，鎖住 priority readback 不再回吐舊 CD/run/source metadata。
+
+**本地驗證結果**：
+- rebase 到 `a7e6de46a feat(delivery): expose p0 reboot drill readback` 後，`DATABASE_URL=postgresql+asyncpg://test:test@localhost:5432/test PYTHONPATH=apps/api python3.11 -m pytest apps/api/tests/test_awoooi_priority_work_order_readback_api.py apps/api/tests/test_delivery_closure_workbench_api.py ops/runner/test_cd_controlled_runtime_profile.py -q`：`35 passed`。
