What ArcSight found in Astro
Real arc impact on Astro (packages/astro) — blast radius, break paths, and evidence. Same question as the homepage: what breaks if I change this?

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 Astro (packages/astro), Change-risk signal at src/assets/fonts/types (fan-in 28) — merge impact can travel beyond the diff you see. Blast radius on src/assets/fonts/types reaches 397 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.
What we'd inspect first

FAQ
- What did ArcSight find in Astro (packages/astro)?
- src/assets/fonts/types: fan-in 28, blast radius 397, CRITICAL. 558 modules and 2,196 dependency edges traced.
- Why does the Astro (packages/astro) structure matter?
- In Astro (packages/astro), Change-risk signal at src/assets/fonts/types (fan-in 28) — merge impact can travel beyond the diff you see. Blast radius on src/assets/fonts/types reaches 397 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 Astro (packages/astro)?
- Start with src/assets/fonts/types. Run arc impact on that file before the change merges.
Key takeaways
- •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.
