ADR-007: Logic & Data Layer Strategy

Status: Accepted

Context

The application requires a decoupled, testable, and robust architecture for logic, environment validation, error reporting, and data handling.

Decision

We centralize business logic, environment validation, and third-party service abstractions in app/lib/.

Rationale

Decoupling logic, observability, and data access from React UI components maximizes testability, isolates runtime side-effects, and allows seamless evolution from mock data to production storage providers (such as Vercel Blob).

Consequences

Components focus purely on rendering and user interaction. All environment parsing (env.ts), structured metadata serialization (json-ld.ts), and error telemetry (error-reporting.ts) are imported from @/lib/.
