What if the AI butchers a customer's name?

It avoids writing names until they're confirmed in full spelling within the exchange — caution beats guess-spelling. If a name does get mangled, the fix takes one click on the lead card, and the line's memory retains the correct spelling for next time. A misnamed customer is still a correctly recorded customer: the transcript is the record. And in the worst case, you take over on the callback, already knowing everything.
