lw-tone-check Audit report.

The tone-melody conflict detector and how to read it (倒字检测器). The one objective, computable criterion this library has - Mandarin dao-zi, where a syllable is heard as a different word because the melody enters it against its tone contour. Covers the correct model (incoming interval versus the syllable's own contour, not previous-end versus next-start), how to run it, how to read a risk score, the three boundaries that make it a risk indicator rather than a verdict, and the five ways to fix a flagged syllable. Use when fitting Mandarin words to a melody, when a sung line is misheard as different words, when checking a draft before delivery, or when a melody must be adjusted to fit words already written. 倒字、依字行腔、字调、声调、检测器、唱出来听成了别的字、唱成别的字、字唱错了、tone_check。
