Additional information

No response

Start by reproducing the failure with codex remote-control start --json and codex remote-control pair --json on the reported macOS and CLI versions. Trace the remote-control connection and pairing entry points, using the timeout and environmentId: null output as the failure signals; done means pairing completes and remote-control start establishes a connection.
