Make orchestration stop, dismiss, and resume deterministic - #13
Conversation
Persist stop intent separately from worker state, keep dismissal non-destructive, resume only orchestration-stopped work, and reconcile late completion and reconnect races. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
📝 WalkthroughWalkthrough本次变更为编排器增加持久化停止意图、停止步骤标记、停止后恢复、dismiss/restore 路由及对应界面状态。服务端、存储层、协议、调度器、测试和文档已同步更新。 Changes编排器生命周期控制
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to While a Stop request is waiting for worker acknowledgement, users may still be able to create tasks or send prompts, allowing additional work to start after stopping was requested and making the run state inconsistent with user intent. Merge should wait until those entry points reject work during the stopping state. Sequence Diagram(s)sequenceDiagram

Reviewed every active comment against the current implementation. Applied — new work was still accepted while Stop awaited acknowledgementThis was valid. A lead can remain Fixed in
Validation: Not applied — docstring coverage warningThis is not a functional correctness issue. Adding comments solely to satisfy an external percentage would conflict with the repository convention to comment only non-obvious behavior; the changed lifecycle functions already document the complex state and recovery rules where needed. @coderabbitai review |

Summary
Makes orchestration Stop, Dismiss, and Resume deterministic across dependency graphs, Node disconnects, concurrent completion, repeated actions, and Host restarts.
State model
Execution, intent, and visibility are now separate persisted facts:
stopRequestedrecords an unacknowledged Stop without pretending the worker is already stopped.stoppedByOrchestratoridentifies only unfinished steps that orchestration Resume may continue.dismissedcontrols visibility without deleting execution history.Stop behavior
cancelledbefore sending Stop commands, preventing new dependency dispatch.Dismiss behavior
Resume behavior
pending.Dependency and race handling
