Proof summary
Four questions every public repository page must answer — see validation record.
Modules to inspect
One row per module. Fan-in is direct dependents. Blast radius is downstream modules reachable from that file.

Why it matters
In NocoDB (packages/nocodb), Change-risk signal at src/db/field-handler/handlers/decimal/decimal.general.handler (fan-in 7) — merge impact can travel beyond the diff you see. Blast radius on src/db/field-handler/handlers/decimal/decimal.general.handler reaches 20 downstream modules. ArcSight answers “what breaks if I change this?” before you ship; high fan-in is a change-risk signal, not a verdict on design quality.

FAQ
- What did ArcSight find in NocoDB (packages/nocodb)?
- src/db/field-handler/handlers/decimal/decimal.general.handler: fan-in 7, blast radius 20, LOW. 1,095 modules and 489 dependency edges traced.
- Why does the NocoDB (packages/nocodb) structure matter?
- In NocoDB (packages/nocodb), Change-risk signal at src/db/field-handler/handlers/decimal/decimal.general.handler (fan-in 7) — merge impact can travel beyond the diff you see. Blast radius on src/db/field-handler/handlers/decimal/decimal.general.handler reaches 20 downstream modules. ArcSight answers “what breaks if I change this?” before you ship; high fan-in is a change-risk signal, not a verdict on design quality.
- Which file should I inspect first in NocoDB (packages/nocodb)?
- Start with src/db/field-handler/handlers/decimal/decimal.general.handler. Run arc impact on that file before the change merges.
Key takeaways
- •Architecture score 95.7/100 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.
