When an MCP session resumes, tool calls that a previous worker process had already dispatched but not yet resolved ("served calls") can now be adopted directly by the new process instead of re-issuing the interrupted turn. The model is told which calls' results were lost via an "orphaned-permission" meta-message, and adoption is logged as tengu_remote_tool_restart_adoption.
MCP session resume can adopt served tool calls left in-flight by a prior worker
