79 Do two things.
80
81 1. For every finding in the review, open the cited code and decide whether the finding describes a defect that really exists in this pull request's code. Label it "real" or "false" and give a one-sentence reason. Judge correctness only; a real defect with an overstated severity is still real.
82
83 2. A defect is known to exist at $expected : $bug_summary
84 Set describes_known_bug to true only if at least one finding describes this same defect, not merely another problem near the same lines.
