+# NOTE: This workflow is DORMANT until a Gitea act_runner is registered with
+# this repo. The active gate today is the host-side pre-push hook
+# (scripts/git-hooks/pre-push) + scripts/ci_gate.py, because our deployment
+# model keeps the app running in a long-lived `qihu-aiflow` container on the
+# docker host rather than building it fresh in CI.
+#
+# To activate later:
+#   1. Install act_runner on the docker host (sharing the docker socket).
+#   2. Register it against this repo with label `ubuntu-latest`.
+#   3. The runner can then `docker exec qihu-aiflow ...` to reach the app.
+#
+# Until then, the pre-push hook already blocks broken pushes.

-## 本版本变更 (v2026.07.18.1 / prod)
-- Phase0 工程纪律止血 启动
-- 新增「部署前镜像备份 SOP」：scripts/backup_before_deploy.py，每次部署前自动提交递增序号镜像快照
-- 统一版本号规范 vYYYY.MM.DD.N + prod/test 标签（取代旧 -recover 标签）
-- 引入后端 pytest / 前端 vitest 测试基建，作为迭代式重构的安全网
-- 固化反复问题的回归用例 R1/R2/R3
-
-## 历史
-- 旧方案：镜像曾用 AIFlow v2.0.1 / v2026.07.14 / v2026.07.14-nav；git 曾用 v2026.07.12-recover / v2026.07.12-ui-recover / v2026.07.13-recover。自 v2026.07.18.1 起统一为 vYYYY.MM.DD.N + prod/test，便于正式版推广后与测试版做环境切割。
-- 历史功能：AI聊天(real API + tool-call function calling)、知识库文件存储 + AI 图谱、频道二维码、邮件/短信配置 + AI 生成、支付配置、平台驾驶舱(token 累计 + 审计/操作日志)、Agent 资源 API、evolution pipeline 自动恢复、全局默认模型、广告位图片上传 + AI 绘图、应用市场安装/卸载/搜索/去重、资产文件类型分类 + 在线预览。迁移 001-015。

+"""Minimal CI gate for qihuaiflow.
+
+This is the canonical, single-source-of-truth gate. It runs the two test
+suites that guard production behavior, INSIDE the long-lived qihu-aiflow
+container (our deployment model keeps the app running in a container, not
+built fresh in CI):
+
+  1. backend pytest  -> /app/backend/python/.venv/bin/python -m pytest -c pytest.ini
+  2. frontend vitest -> /app/frontend && npx vitest run
+
+Exit codes:
+  0  all suites green  -> deploy/push may proceed
+  1  a test suite failed -> BLOCK (do not deploy/push)
+  2  environment error  -> docker missing or container not running
+
+It auto-detects where it runs:
+  * If the qihu-aiflow container is reachable via LOCAL docker (i.e. on the
+    deploy host), it execs directly.
+  * Otherwise it falls back to ssh_helper (remote control from a laptop),
+    which reaches the host over SSH and execs into the container there.
+
+Usage:
+  python scripts/ci_gate.py
