Read Code Moves Faster Than Understanding

Attention is the amount of human scrutiny required before an artifact should be trusted, approved, merged, published, or acted on.

It is not the severity of any single finding. It is not the verdict. A high-attention artifact can still be LGTM after careful review. A low-attention artifact can still request changes if a clear issue is found.

Attention should be based on blast radius, reversibility, observability, verification difficulty, evidence quality, and whether the artifact changes future engineering understanding.
