Prompted by a real incident: Confab's process silently wedged, and was indistinguishable from "just idle" after the fact — lsof showed the CLI socket held open, every connection was refused, and nothing had been logged for the rest of that session. No crash, no error. - CLIServerService: NWListener's state transitions are normally near-instant, but had no bound on that assumption. Now times out after 8s if .ready is never reached, logging clearly and clearing the listener slot instead of silently pretending to work forever. - oAIApp: a 5-minute heartbeat log line, otherwise meaningless on its own, turns "the log's gone quiet" from an ambiguous signal into a plain read of roughly when a future freeze started. Neither fixes a known root cause (none was found - no crash report, no error, just silence), so this is diagnostics and a narrow failsafe, not a claim the underlying freeze is resolved.
