Error Handling

Priority: P1 (HIGH)

Standardized functional error handling using dartz and freezed failures.

Implementation Guidelines

Either Pattern: Return Either<Failure, T> from repositories. No exceptions in UI/BLoC.
Failures: Define domain-specific failures using @freezed unions.
Mapping: Infrastructure catches Exception and returns Left(Failure).
Consumption: Use .fold(failure, success) in BLoC to emit corresponding states.
Typed Errors: Use left(Failure()) and right(Value()) from Dartz.

Reference & Examples

For Failure definitions and API error mapping: See references/REFERENCE.md.
