+## 2026-06-29 — 21:43 P0-006 reboot SLO API readback promoted
+
+**照優先順序完成的實作**：
+- P0-005 credential escrow evidence refs 已由 production API / Delivery Workbench 讀回 closed；最新 Gitea CD #3968 / #3969 皆 success。
+- P0-006 仍是 active P0，唯一 blocker 維持 `host_boot_observation_older_than_target_window`；未從此 lane 重啟主機或 restart service。
+- 將 P0-006 `/api/v1/agents/reboot-auto-recovery-slo-scorecard` 的主線判斷值提升成 top-level readback：`active_blocker_count`、`readiness_percent`、service/data/backup green、observed/stale hosts、verify-only metric 與 StockPlatform freshness / ingestion 狀態。
+
+**驗證**：
+- Focused pytest：P0-006 scorecard / Delivery Workbench / CD profile `24 passed`。
+- `ruff check`、`py_compile`、`git diff --check`、Gitea runner pressure guard、Gitea secret env guard：通過。
+
+**邊界**：未操作 host / Docker / K8s / DB / firewall / Wazuh runtime；未觸發 workflow_dispatch；未使用 GitHub / `gh` / GitHub API；未讀 secret / token / raw sessions / SQLite / `.env`。
