OpenClaw 4.2 Task Flow Internals, Managed Child Spawning, and the Architecture Behind Durable Orchestration

PR #58930: TaskFlow Managed Substrate Merged Into Main

This is the foundational PR that shipped the durable flow record model, SQLite persistence with WAL mode, CAS-based mutation helpers, and the openclaw flows CLI commands. If you want to understand what Task Flows actually are under the hood, start here before reading any blog post about 4.2.

PR #59610: Managed Child Task Execution Lands on Top of the Flow Substrate

This is the follow-up PR that actually made Task Flows useful by letting a managed flow spawn child tasks under itself with sticky cancel intent. The cancel propagation design is the key detail: parent marks stop intent first, then shuts down children, then settles once they finish. No more orphaned tasks.
