False Positive: punctuation error

**What got flagged?**
Any resemblance to real persons, living or dead, is purely coincidental.

**Why is this incorrect?**
This is a correct usage. The solution proposed by Harper will cause a punctuation error.

Start by reproducing the reported sentence in Harper and identify which punctuation rule flags it. Trace that rule to its implementation and existing tests; done means the sentence is accepted without weakening detection of genuine punctuation errors.
