Answer: A human-in-the-loop review step before each letter is sent
Human in the loop is one of Google's recommended practices for the limitations that remain after grounding, and Google's own security guidance keeps humans in the loop for critical decisions. When every residual error carries regulatory cost, a review gate is what stops one reaching a customer. A second grounding source, a lower temperature and a fine-tuning run all push the error rate down without ever driving it to zero.
