During July 2025, work on the factcast/factcast repository centered on enhancing time-related APIs and improving locking safety within the Factus interface. Using Java and core backend development skills, default time retrieval methods were introduced, delegating time queries to FactStore and ensuring consistent, reliable access to time-sensitive operations. Comprehensive JavaDoc and usage documentation were added to clarify API usage and support client synchronization. Additionally, error handling was strengthened by enforcing explicit exceptions when attempting to lock non-existent aggregates, preventing unintended instantiation. This combination of API design, robust error handling, and thorough documentation contributed to greater reliability and maintainability in the codebase.
