// 钉住组合根侧的接线契约：buildAccountAdapter 构造 qq-obv11 适配器时必须把 channelFactory
// 手上的 logger 传进去（与 kook/telegram/webhook 同口径，见 cmd/cyrene/channels.go）。缺陷
// 形态：漏传 ⇒ 适配器自造默认 INFO 兜底 ⇒ 入站帧取证（DEBUG）全部静默丢弃，主人要查的
// 「群友 @ 没回 / 戳一戳没反应」在日志里一片空白，且与「上游压根没上报」无法区分。
//
// 断言走**真实入站路径**：真开一次 http+server 端、真 POST 一条 OneBot 上报，再看注入的
// 捕获器里有没有 `msg="inbound frame"`。所以只要接线一断，这条测试必红。
