May 2025 monthly summary: Delivered operational enhancements and stability improvements across services and docs, enabling more robust comb auction support, safer solver interactions, and clearer deployment and pricing guidance. Key features delivered include introducing a new reference_scores table to replace the obsolete settlement_scores for comb auctions (backward compatibility preserved; actual reference score calculation deferred to a future PR), and augmenting the build script with Polygon ethflow deployment address and deployment block information to ensure correct interaction with the Polygon network. Major bugs fixed include removing unused tx_from and tx_nonce columns from settlements (schema and docs updated) and switching baseline buy amount calculation from ceil_div to floor division to prevent overly generous solver outputs and reduce on-chain reverts in new network environments. Overall impact: improved data models and deployment reliability, reduced schema debt, and more stable solver behavior, contributing to higher reliability and predictability of auctions and price estimation. Technologies/skills demonstrated: SQL schema migrations and documentation updates, build/script automation for cross-network deployments, backward-compatibility-aware change management, and enhanced solver stability practices.
