About 30 fixed rectification lines lose the receipt tone: no 「已记录。」 openings (收到 when the range holds, 好 when it moves), 麻烦 instead of 请, 时间 instead of 候选 in what the user reads, and no 「新建对话」 after adoption. Numbers, clocks, ranges and the honesty boundaries are unchanged. CHOICE_ACK_RE also recognises the new acknowledgements, so a model sentence that repeats one is still dropped; the delivery guard matches the delivery sentence by containment and does not depend on the opening.
