Jun 1, 2025June 2025 monthly summary for hydro-project/hydro focused on stabilizing distributed consensus (Paxos) path, memory management, and test coverage. Reverted anti-join allocation in dfir_rs to address memory management and potential performance issues, and added a unit test ensuring Paxos compiles and yields non-negative throughput, improving reliability and test coverage. Overall, these changes enhance stability under load, reduce risk of memory-related regressions, and support predictable throughput.
