You now have a repeatable process for diagnosing OpenClaw problems. Start with openclaw status and openclaw doctor. Then use openclaw logs --follow when you need to watch live output.
You know the common gateway errors and their exact fixes. You know about the Telegram negative-ID bug and the Discord Message Content Intent requirement. You know that error messages can lie (issues #5240 and #10368). And you know that Node causes SQLite compatibility problems.
When something breaks, you have the ladder. Climb it before guessing.
