During July 2025, Bernhard Streit enhanced the factcast/factcast repository by improving time-related APIs and strengthening locking mechanisms. He introduced default time retrieval methods in the Factus interface, delegating to FactStore, and provided comprehensive JavaDoc and usage documentation to clarify client synchronization. Using Java and focusing on backend development and API design, Bernhard also addressed error handling by ensuring that attempts to lock non-existent aggregates in FactusImpl now throw explicit exceptions, preventing unintended instantiation. His work emphasized reliability and maintainability, delivering both new features and robust fixes that improved the consistency and safety of time-sensitive operations within the system.
