After deleting the user's DEFAULT vault (old `Engram`, 4c2057f9), the MCP connection fails `not_found` on EVERY call — including `list_vaults` and the no-arg `set_vault()` reset — because the client's default-vault pointer dangles at the deleted vault.\n\nImpact: any customer who deletes their default vault hard-breaks their Claude/MCP integration with no recovery path from the client side.\n\nFix directions:\n1.
