Apr 1, 2025April 2025: Delivered epoch-bound network rule management and Allegro-grade governance for the sonic repository, with a strong emphasis on reliability, upgrade readiness, and test coverage. Implemented epoch-aware MinBaseFee updates, deep-copy safeguards for pre-Allegro paths, and comprehensive validation and gas-cost governance. Enhanced persistence across restarts and added extensive tests to ensure correctness during upgrades and across versions. This work reduces upgrade risk, improves predictability of network behavior, and strengthens cost governance for large-scale deployments.
