OpenClaw Breaks After Homebrew Updates Due to Mixed Node/Runtime/Plugin Cache Drift

Every OpenClaw release breaks something. v2026.3.22 broke the Dashboard and WhatsApp. v2026.3.2 silently disabled all agent tools. v2026.3.8 killed cron jobs and compaction. v2026.3.28 permanently broke the exec tool in a way that downgrading could not fix. Users discover these regressions after upgrading their production instance. There is no pre-upgrade testing, no rollback plan, and no way to know if a new version will break your specific configuration. This tool creates a sandboxed replica of your OpenClaw setup, runs the upgrade there first, executes your critical workflows against it, and gives you a pass/fail verdict before touching production.

The OpenClaw gateway silently restarts every 50 minutes killing all active ACP sessions. Telegram integration crashes with AbortError every 20-30 minutes. The doctor --fix command hits a stack overflow and generates thousands of clobbered backup files instead of recovering. After updates, the gateway fails to restart because npm overwrites dist/ while the process is still running. There is no reliable supervision layer that keeps the gateway running, detects crash loops, and recovers gracefully. This tool wraps the gateway in a battle-tested supervisor that handles all known failure modes and keeps your agents online.
