Scan summary Repository scanned at 96.6/100 with 66.7% coverage. It contains 784 nodes across 3 cross-layer flows, written primarily in mixed languages. Engine surfaced 27 findings — concentrated in quality (19), software (5), security (2). Risk profile is high: 0 critical, 1 high, 2 medium. Recommended next step: open the quality layer findings first — that's where the highest-impact wins live.

Showing 16 of 26 actionable findings. 27 raw detector signals were grouped into reader-sized issues. Click TP / FP to vote on a finding's accuracy — votes adjust the confidence weighting and improve detection across the platform.

high System graph security auth conf 1.00 FastAPI POST `simulate` without auth dependency — src/dataflow_sim/app/server/main.py:377
`@router.post` decorator with no `Depends(get_current_user)` or auth-shaped dependency in its signature. Mutating endpoints should require authentication unless explicitly public.

medium System graph quality Integrity conf 1.00 `fetch()` without try/.catch or AbortSignal — ui/src/App.tsx:183
Bare `fetch(...)` will throw an unhandled rejection on network failure. Wrap in try/catch, attach a `.catch(...)`, or pass an AbortSignal with a timeout.
runtime safetyRobustness
medium System graph security Coverage conf 1.00 No auth library detected
The scanner did not find any standard auth library (JWT, OAuth, NextAuth, Auth0, etc.). The repo has auth/admin/session surface indicators, so auth may live in custom code, in a separate service, or be missing.

low System graph quality Production readiness conf 1.00 Composite production-readiness gap
Multiple low-cost hardening controls are missing together: license, ci. Opus verification showed these co-occurring gaps are a better readiness signal than reading each flag in isolation.

low System graph quality Debug conf 1.00 Debug logging residue appears in source files
Found 49 console/debugger/print-style debug statements in non-test source. This is a common fast-generation residue before production cleanup.

No LICENSE/COPYING/NOTICE file was found. Generated repositories often omit licensing, which blocks reuse and automated intake.

Names with suffixes like `_old`, `_v1`, `_deprecated` usually indicate replaced-but-not-removed code (typical AI-coder leftover). Confirm and delete, or rename if it's the active version.

low System graph api Wiring conf 1.00 Unused endpoint: GET /api/health
`src/dataflow_sim/app/server/main.py` declares `GET /api/health` but no frontend code we scanned calls it. This is fine if the endpoint serves external clients (mobile app, third-party, server-side webhooks). Otherwise it's dead code — consider removing or documenting who consumes it.
