Run Lifecycle

标准状态

• queued
• submitted
• running
• retrying
• canceling
• succeeded
• failed
• canceled

合法转移

• queued -> submitted
• submitted -> running
• submitted -> failed
• running -> succeeded
• running -> failed
• running -> canceling
• canceling -> canceled
• failed -> retrying
• retrying -> submitted

规则

• 终态为：succeeded、failed、canceled
• 终态 MUST 不可逆
• canceling 是中间态，表示取消请求已被接受但尚未完成释放
• 进入 retrying MUST 创建新 attempt，而不是覆盖原 attempt

触发源

• 控制面命令
  • submit / cancel / fail
• runtime 事件
  • started / finished / error
• orchestrator 决策
  • retry / timeout / provider failure

约束

• 一个 run MUST 只能拥有一个当前状态
• 一个活动 attempt 对应一个主 provider session
• 进入终态后，允许 projection 继续追平，但不允许新增业务输入
