// @umt/tasks 自带的三张表(W2 合并进 packages/db 迁移流程):
|
|
// - tasks_run_meta:引擎 run 的业务侧元数据(traceId/优先级/取消标志),取消标志是 abortSignal 的来源
|
|
// - tasks_fact:signal 之前先落库的事实;waitForFact 以它为准,信号只用来加速唤醒
|
|
// - tasks_op_ledger:操作账本(fencing),记录 attempt_token,旧 attempt 的提交会被拒绝
|
|
|
|
// biome-ignore lint/suspicious/noExplicitAny: 迁移不依赖应用表类型
