PR #58930: Task Flow Managed Substrate Merged Into Main

This is the foundational PR that makes durable orchestration real in OpenClaw. It adds FlowRecord persistence via SQLite, CAS-based mutation, managed vs mirrored sync modes, and the openclaw flows CLI for inspection and recovery. No DAG engine yet, just a clean substrate that everything else builds on.

PR #59610: Managed Child Task Execution Lands with Sticky Cancel Intent

The execution layer on top of the restored substrate: managed TaskFlows can now spawn child tasks and cancellation stamps cancelRequestedAt before shutting down children, so orchestrators stop scheduling immediately and children settle cleanly. This is the PR that turns TaskFlow from durable state into an actual parent-job primitive.

Analysis

4.2 Operator Breakdown: before_agent_reply Hook, Slack mrkdwn, and Google Assistant Launch Surface

Covers the features that did not get much attention in the raw release notes: the before_agent_reply plugin hook lets you short-circuit the LLM entirely for deterministic responses, and Slack now gets native mrkdwn formatting instead of raw markdown bleed. Both are real leverage points if you run OpenClaw on high-traffic channels.

Stack Observer: Task Flow Config Migration Guide and Production Deployment Notes

Best practical write-up on what the breaking config changes actually require from DevOps teams, with clear before-and-after paths for xAI and Firecrawl integrations. The framing around plugin-owned namespaces reducing configuration conflicts is the right way to think about why this migration matters long term.
