FAQ

What did ArcSight find in BullMQ?
BullMQ has 95 modules and an architecture score of 94/100.
Why does the BullMQ structure matter?
The BullMQ score is 94/100 across 95 modules and 277 edges.
Which file should I inspect first in BullMQ?
Start with src/interfaces/repeat-options. Run arc impact on that file before the change merges.

Key takeaways

  • •Architecture score 94/100 indicates a healthy structure with room to reduce cycles and violations.
  • •Structural scan reports dependency cycles — inspect impact paths before refactors that cross module boundaries.
  • •High fan-in modules are change-risk zones; run arc explain <path> before refactoring.
  • •Run the full workflow (analyze, hotspots, explain, impact, snapshot, drift) in your repo for deterministic architecture insights.

Run ArcSight on your repo
