Scan summary Repository scanned at 100.0/100 with 66.7% coverage. It contains 43820 nodes across 0 cross-layer flows, written primarily in mixed languages. Engine surfaced 24 findings — concentrated in quality (19), software (1), api (1). Risk profile is low: 0 critical, 0 high, 2 medium. Recommended next step: open the quality layer findings first — that's where the highest-impact wins live.
