M4: 范式引擎与任务运行时

skill-engine(L4):载方法不载权力(白名单外工具即拒)、结晶片段经 ToolInvoker 留痕、
  装配入信封、技能目录渐进披露

flow-engine(L5):四种步型、确定性谓词跳步、重试与声明给定的兜底、
  异步步即监听(时限必配)、写类工具登记动作意向、步序位置持久

loop-engine(L5):自研 CMMN 子集解析器(表外构件直接报错,子集封顶可机器证明)、
  两副标准生命周期与迁移拓扑(引擎不得私改)、Enabled ≠ Active、
  语义性前提标待裁量评估(引擎不代裁量)、DMN 确定性求值 + 命中行留痕、
  DRD 缺口演绎与拓扑序、双向驱动与交集导航(断点即人环)、三型行动、
  终局唯放行与 Harness

task(L6):终态五名裁定(released 唯一成功)、Harness 预算环外强制与停滞熔断
  (监听中是健康态)、控制三语义(叫停不是终态,记最重档纠正)、改派留痕通知双方、
  断点续跑三份持久状态、封卷触发蒸馏钩子

301 个测试通过,门禁五道全绿
