优化前先测量
先测量问题。将每日总和存储在每晚刷新的物化视图中，使仪表盘查询读一行而非扫描百万行。 最常见的错误是未确认门禁能捕获你关心的问题就先加上。在接入 CI 之前，先对当前代码库运行 CREATE MATERIALIZED VIEW daily_sum AS SELECT date, SUM(amount) FROM sales GROUP BY date; 并检查输出。
CREATE MATERIALIZED VIEW daily_sum AS SELECT date, SUM(amount) FROM sales GROUP BY date;验证改进效果
门禁就位后，让失败可操作。CREATE MATERIALIZED VIEW daily_sum AS SELECT date, SUM(amount) FROM sales GROUP BY date; 失败时应指向具体文件和行号，而非泛泛的错误。在锁文件中固定工具版本，防止上游发布悄悄改变行为。每次拉取请求都应像审查测试结果一样审查门禁输出。
验证
在本地运行 CREATE MATERIALIZED VIEW daily_sum AS SELECT date, SUM(amount) FROM sales GROUP BY date; 确认通过后推送。CI 中门禁应阻断不合规的拉取请求。若人为绕过门禁直接推送，应在下次定期扫描中被发现。
注意事项
- The gate only runs on events that trigger the workflow; locally pushed commits bypass it.
- Configuration drift is possible if someone edits settings outside version control.
