Coverage Gap Finder

Reads your coverage report (lcov, Istanbul, v8), weights untested code by cyclomatic complexity and git churn, and produces a prioritized list of "where to add tests for real ROI" — not just files ranked by line coverage %.

Raw coverage percentage is misleading. 90% coverage with the 10% gap on your payment logic is worse than 70% coverage with tests in the right places. This skill finds the risk-weighted gaps.

- lcov / Istanbul / v8 report parsing - Cyclomatic complexity scoring - Git-churn weighting (recently-changed code is higher risk) - Critical-path detection (what does production actually run?) - Test-first prioritization
