Claude CLI subprocess route can stall when exact model ids are collapsed to broad family aliases and fresh-run watchdog is too low

A local agent gateway routed Anthropic work through Claude Code CLI print-mode subprocesses. After switching back to the CLI route, activity-page runs intermittently failed with no assistant output and user-visible abort/no-output errors. The gateway had also lost session identity in child hooks, and scheduled checkpoint jobs were competing with user turns.
