真因（agent-221 用三条独立证据推翻了「SenderID 为空」的假设）：ev.UserID 有值； owner.yaml 的 qq 条目是 10:37:57 才加的（此前那几条判陌生人属**正确的 fail-closed**）； 而热重载成功后仍不对 —— 因为 internal/channel/session/manager.go 的 GetOrCreate 对**已绑定的渠道直接返回缓存会话**：判主门槛用新 actor 会过（所以她会回话）， 但**车道用的是缓存的旧会话**（Owner=false ⇒ 不镜像进 Web 主会话、MemWritable=false、 落盘 actor_role 永不更新）。 修：缓存命中但 ActorRole 与本次解析不一致 ⇒ rebindLocked 刷新车道 + 同步落盘 （updateActorRoleSQL）；persist 的 INSERT OR IGNORE 后读回落盘车道、不一致就地纠正 （覆盖上一轮进程留下的旧行）；落盘失败只 WARN（不因记账失败丢主人消息）； **身份变化不搬家、不换 session id**；车道只来自 ResolveActor 的结构化白名单判定。 QQ 适配器（防御加固，非本次真机 bug 的修复）：senderIDOf 兜底链 顶层 user_id → sender.user_id；并用完整论证钉住「**群聊绝不能用 ChannelID 兜底**」（否则群里任何人 可顶群号冒充主人）；顺手体检：自己发的消息（post_type=message_sent）与 meta_event 已被 handlePayload 过滤。为守 ≤500 行把 id/字符串小工具拆到 ids.go。 测试：session/ownerlane_test + qq/ownerlane_test 新增用例（含「群号等于主人号时 陌生人不得借群号冒充」「群聊发送者 id 缺失时 SenderID 必须为空而非群号」「白名单 热重载后车道立刻刷新且 session id 不变」「白名单移除后立即退回，不是单向提权」 「跨进程继承的旧行被就地纠正」）。 变异 5 条（去 sender.user_id 兜底 / 群聊用群号当 SenderID / 命中却判 unknown / 还原缓存直返 / 去掉旧行纠正），每条先确认可编译、贴红行、还原复绿（md5 逐字节校验）。
