Scan summary Repository scanned at 99.9/100 with 77.8% coverage. It contains 837 nodes across 0 cross-layer flows, written primarily in mixed languages. Engine surfaced 4 findings — concentrated in api (1), frontend (1), security (1). Risk profile is low: 0 critical, 0 high, 1 medium. Recommended next step: open the api layer findings first — that's where the highest-impact wins live.
