Module validation_service 

Services for validating decoded JWTs against application expectations.

This submodule contains JwtValidationService, which validates raw token strings using a configured codec and checks issuer expectations.

Use this when a boundary in your system receives a raw token string and you want a clear, typed validation step before handing claims to higher layers.

The service keeps validation behavior narrow and explicit:

• decode the token with the configured codec
• reject tokens that fail codec-level validation
• reject tokens whose issuer does not match the configured issuer

Expiration, signature, and other JWT-level checks remain owned by the configured codec and its underlying JWT validation settings.
