import com.articon.base.api.v1.analytics.statistics.dto.*

What's wrong: A class in domain/ directly depends on classes in api/v1/. Per the layering documented in CLAUDE.md (api → application → domain → infrastructure), the dependency arrow must point inward — domain must not know about api.

Why it matters: Any DTO change (rename, split, wire-format tweak) drags into the domain layer. Versioning the REST contract becomes painful, and domain tests pull api types onto the classpath unnecessarily.

Suggested fix: Define a domain-level result type under domain/analytics/statistics/...; have api/v1/.../StatisticsController map domain results to wire DTOs. The mapper belongs in api, not in domain.
