// ★ 升级后**旧版按账号拆的源必须被清掉**,否则同一个渠道的模型出现两遍。
//
// 真实事故(2026-10-19 用户报「同一个模型两个名字 / 源列表一堆不可读的东西」):
// 生产 config.yaml 里 6 对源并存 ——
//
// channels-trae-b8dd6b3df30e + channels-trae
// channels-buddy-buddy-main + channels-buddy
// …(trae/lobsterai/minimax/buddy/codearts/zcode 各一对)
//
// 新设计是「一通道一源」(`channels-<provider>`),换号靠同名 add_source 覆盖
// api_key。旧版是「一账号一源」(`channels-<provider>-<账号id>`)。升级时必须把
// 旧形态清掉,否则:
//
// ① 模型列表里同一模型出现多遍,只能靠 12 位 hex 区分(人读不出来)
// ② 旧源指向已不该用的账号,却可能因为注册更早而**先**被调度到
//
// 根因是形态假设错了:内核 `list_sources` 返回**裸数组**(见 kernel_actions.go
// 的 actionListSources,直接 `return out`),而迁移代码按 `{sources:[...]}`
// 信封去取 ⇒ 恒为 nil ⇒ 循环一次都不跑 ⇒ 静默什么都没清。
//
// ★ 本判据的关键是**用裸数组形态喂数据**(也就是内核真实返回的形状)。
//
// 如果按信封造夹具,即使代码是错的两边也"对上了",测不出任何东西 ——
// 这正是这个 bug 逃过全部既有判据的原因。

-- ★ 内核 `list_sources` 返回的是**裸数组**(kernel_actions.go 的
-- actionListSources 直接 return out),不是 {sources=[...]} 信封。
-- 此前这里取 ls.json.sources ⇒ 恒 nil ⇒ 循环一次都不跑 ⇒ 旧版按账号
-- 拆的源永远清不掉,同一个渠道的模型于是在列表里出现两遍(靠 12 位
-- hex 区分),用户看到的就是"同一个模型两个名字"。
-- 三种形态都认,但**裸数组必须优先** —— 它才是内核的现行契约。
