[exceptionfactory]

Summary

The integration looks well designed and comprehensive. Reusing the existing encryption implementation preserves the persisted format and upgrade compatibility, while the new context-aware API is applied consistently across flow properties, parameters, and OIDC tokens. The unit tests and system test provide good coverage of the main behavior. Nice work, will merge pending green checks.
