Before outputting the results, you must first perform **structured thinking** within the <why>...</why> tags according to the following steps:
<why>
[Global Context]: Summarize the original text's worldview, background setting, and rule system in one sentence.
[Core Constraints]: Reiterate the 1-2 "red line" rules most likely to go wrong in the current text.
[Edge Cases]: Pick out 3-5 of the most difficult-to-judge terms, and briefly outline the logic in the format of `Original -> Result (Reason)`.
</why>
