// order-expire/usage-refresh/refund-apply-sweep/refund-stuck-alert/sync-pending/
// paid-spotcheck + P8 Task6 crypto-orphan-scan)确实全部被注册 —— main() 原先把这段
// 装配写死在函数体内,没有任何测试保证"漏挂一个任务"能被发现;抽成
// reconcile.Assemble(见 internal/reconcile/assembly.go)后可以直接断言注册出的任务名
// 集合,main.go 现在只是薄薄一层调用(逐行照抄原实现,未改调度语义)。
//
// pReg 同时注册 fake + crypto 两个渠道:crypto-orphan-scan 只在 crypto 渠道已注册时
// 才由 AddCryptoJobs 挂载(见其函数注释),不带 crypto 就测不到这第 7 个任务。
