新流程包端到端:从零建一条流并跑通 —— 编排层可独立开工的验收证据

八例 unified-quote 证明的是「既有这条流能跑」;这一例证明另一件事:
**拿编排层去开一条新流,不碰活动一行代码**。走的正是设计者那条路 ——
建包(草稿,不生效)→ 链接已装载的活动 → 激活(双判据闸)→ 起单 → 走完。

六例(真库):
① 建包存下来是未生效草稿;未生效版起单被拒(一次只能激活一个版本)
② 激活闸判据一:图编排不闭合 → NotClosedError
③ 激活闸判据二:活动未装载(unknown-activity)→ NotClosedError
④ 两面都齐即可激活,一条流恰一个生效版本
⑤ 起单跑通:受理 → 审批(运营时分配审批人)→ 归档 → 闭环,末态 completed
⑥ 新流与老流引用同一批活动各跑各的 —— 建新流没动到活动

这条新流(quick-archive:受理→审批→归档)只用了编排层的能力:
节点两种、条件出边(审批点的 verdict 出边)、边映射五源、激活双判据。
