Every cut looked reasonable. What plays is the attempt.

When a line was recorded three times, the rule is to delete the earlier attempts and keep the last one — the take where the speaker finally got it out. Invert that and nothing looks wrong: each deletion is defensible read on its own line, the transcript still parses, and the thing that ships is "因为今天有什么值得研究已经被我外" — a sentence that stops mid-word.

The checker is free and needs no account. Paste the transcript and the cuts and it rebuilds what will actually play, in playback order, because adjacency after cuts is not adjacency in the file. Then every repeat group against the ordering rule, and every join for the three things a cut list cannot show you: a splice mid-sentence, a line that still says "this one" after the thing it pointed at went, and a piece that now ends on a connective. Where two takes cannot be told apart mechanically it says so and asks you to read both, rather than guessing. Every lane ships a worked example that costs nothing. Writing the report needs credits.
