codex execis the non-interactive subcommand.--sandbox read-onlyis the default for exec and keeps the reviewer from modifying the repo.--jsonemits a JSONL event stream rather than a single JSON object.result_path: nulluses the raw stream as the review text; the synthesizer can still extract useful content from it. If that proves noisy, switch to a non-streaming flag.paid: truetriggers the checkpoint-1 warning. Disable for routine runs and re-enable when you want the full panel.
