error-handling-exceptions

The best way to handle domain-specific exceptions is to map them to clear business semantics while preserving the original error context. This avoids wrapper noise and ensures observability across domain, data, and application layers without obscuring the root cause.

Catch-and-rethrow wrapper noise obscures root causes because it wraps errors in generic containers that hide business semantics. This degrades observability and hinders proper decision-making by masking the original error context needed for debugging.

To define stable domain exception types, replace generic exceptions with specific business outcomes like NotFound, ValidationFailed, or PermissionDenied in your domain service. This enforces clear business semantics and signals precise control flow.

You need domain-specific exception management when exception mapping affects control flow, validation, and observability across domain, data, and application layers. It standardizes error handling by enforcing precise domain errors and reducing wrapper noise.

Yes, enforcing domain-specific exceptions works without external dependencies because it relies on standardizing internal architecture. You define stable domain exception types within your existing codebase to improve code quality and error handling.

Generic exception handling limits business semantics by failing to distinguish specific outcomes like validation failures or permission denials. It introduces wrapper noise that obscures root causes and degrades observability across application layers.
