When no server is reachable, the REPL now automatically spawns a qpq-server child process with dev defaults (--allow-insecure-auth, matching TLS cert paths). The server is killed on REPL exit via a Drop guard. Use --no-server to opt out (e.g. for remote servers). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
