ProcessPreflight caught JFJochException only. The pusher is blocked on this ACK and reads its absence as a dead writer, so anything else escaping to Run()'s generic handler cost the caller the real reason and handed it a five-second timeout instead - for a check whose entire purpose is to report the problem before the detector is armed. std::filesystem::exists is the concrete leak: it throws filesystem_error, not JFJochException, when the output path cannot be walked at all (a directory component with no search permission, a symlink loop), which is exactly the misconfiguration worth catching early. Now catches std::exception, as JFJochReceiverService::Start does. Also corrects the comment above the write_master_file assignment in TCPStreamPusher::Preflight, which claimed index 0 had to fall on the same connection here as in StartDataCollection. It does not, and cannot be made to: Preflight filters the pool on connected && !broken, while START re-derives its index 0 after DetachDeadConnections, which additionally drops anything failing IsConnectionAlive - so a writer lost in between shifts it. That is harmless, because every writer of a run works on the same filesystem and so answers the same question about the same files. The comment now says that instead.
