BR_READ_ONLYMaster switch. Set to '1' to disable all write-side tools across NF-e, NFC-e, NFS-e, AND CT-e (br__submit_nfe, br__distribute_dfe, br__submit_nfse, br__cancel_nfse, br__submit_cte, br__cancel_cte, br__correct_cte). Read-only mode for safe exploration. Setting only this variable is sufficient to disable all CT-e writes too — BR_CTE_READ_ONLY is an additional, independent gate, not a required second step.
BR_CTE_READ_ONLYSet to '1' to disable the three CT-e write-side tools (br__submit_cte, br__cancel_cte, br__correct_cte). Independent of BR_READ_ONLY — either variable being set to '1' is sufficient to block CT-e writes; use this one to gate CT-e alone while leaving NF-e/NFS-e writes enabled.
LOG_LEVELLogging level: DEBUG, INFO (default), WARNING, or ERROR
