+## 2026-07-01 — 08:54 CD host pressure interrupted / Postgres recovery classifier
+
+**照主線修正的問題**：
+- Live Gitea queue 顯示 sustained-load automation commit 已到 main，但正式 deploy 未完成；CD `#4199` 在 tests stage 的 `wait-host-web-build-pressure.sh` 第 2 次等待後被 `signal: interrupt` 中斷，log 只留下 `k3s-postgres-recovery CPU cores 3.595200 > 2.0`，沒有跑到 fail-hard refusal 結尾。
+- `ops/runner/read-public-gitea-actions-queue.py` 新增 host pressure classifier 欄位：`host_web_build_pressure_interrupted`、`latest_visible_cd_host_pressure_interrupted`、`latest_visible_cd_postgres_recovery_cpu_pressure`、CPU cores / threshold 與對應 rollups。
+- 此補丁不打開 110 capacity gate、不把 pressure gate 改成 warn-only；只把模糊 `host_web_build_pressure_waiting` 轉成可被 AI Agent / PlayBook / RAG 使用的明確 blocker evidence。
+
+**驗證**：
+- `python3.11 -m pytest ops/runner/test_read_public_gitea_actions_queue.py -q` 通過（30 passed）。
+- `DATABASE_URL=postgresql+asyncpg://test:test@localhost:5432/test PYTHONPATH=apps/api python3.11 -m pytest ops/runner/test_read_public_gitea_actions_queue.py apps/api/tests/test_harbor_registry_controlled_recovery_receipt.py apps/api/tests/test_awoooi_priority_work_order_readback_api.py -q` 通過（58 passed）。
+- `python3.11 -m py_compile ops/runner/read-public-gitea-actions-queue.py`、`python3.11 ops/runner/guard-gitea-runner-pressure.py --root .`、`git diff --check` 通過。
+
+**邊界**：只改 public Gitea queue readback parser / tests / LOGBOOK；未讀 secret / token / `.env` / raw sessions / SQLite / auth；未使用 GitHub / `gh` / GitHub API；未 workflow_dispatch；未 SSH 寫入、未重啟主機、未 restart Docker / Nginx / K3s / DB / firewall；未恢復 legacy / generic runner label。
