MCP server stays unavailable forever for existing sessions after transient startup failure

증상

Behavior bug (incorrect output/state without crash)

원인

Model generated plausible but incorrect output due to insufficient grounding, missing verification, or high sampling temperature.

해결법

sees and executes the MCP tools correctly.

1. Return to the session from step 4. The MCP tools are still missing. They never appear, regardless of:
   • gateway restart (openclaw gateway stop / start, or docker restart)
   • full container reboot
   • waiting any amount of time
2. (Variant) Add a new MCP server to openclaw.json while sessions already exist. Existing sessions never see the new server’s tools either.
