It is theoretically possible for confidence score to be 0.0, as it is a valid result of steppiness (However is not always displayed due to the check for confidence_in_culprit seeing 0.0 and evaluating it as False in the template). All branches that lead to auto actions have been verified to check for sufficient confidence score before proceeding. |
