Refactor types for better readability

**Description**
Currently validation lacks proper export support.

**Proposed solution**
Add configurable export with sensible defaults.

**Priority**: Low/Medium

Start by locating the validation logic and the existing export handling in the Shell codebase. Determine how validation currently behaves, then define and verify configurable export with sensible defaults; the issue provides no file or test entry point, so confirm the expected behavior with maintainers before changing code.
