What it is
What is visible in the shipped code. One signal is not a verdict. The score is the whole weighted set, not any single line of it.
How it is weighted
4 points is deliberately light. This one is a hint, and it is only interesting alongside others.
What to do about it
Turn off source map generation for production builds, or stop serving the .map files.
Where it fires
None of our worked examples trip this one, which is itself informative — it means the pattern is rarer than the tells that fire constantly, so when it does show up it is worth paying attention to.
