Root cause: gateway restart is async (systemd), but validateNoReplyModelAvailable()
ran immediately after, hitting a race condition where the new gateway process
hadn't finished initializing yet. This caused 'model not listed' validation
failures, triggering config rollback even though the config was correct.
Changes:
- Add waitForGatewayReady() that polls 'openclaw gateway status' for RPC probe
- Add retry loop (5 attempts, 2s interval) to validateNoReplyModelAvailable()
- Fix CONFIG.example.json: contextWindow 4096->200000, maxTokens 64->8192
(OpenClaw requires minimum 16000 contextWindow)
