October 2025 Summary: Focused on stabilizing CSM tests and ensuring coverage parity across networks in lidofinance/scripts. Key actions included implementing a prefetch-based data pipeline for contract data using the v2 Etherscan API and aligning penalty value retrieval with the system parameter/bond curve logic to reduce false failures. On the secondary network, test selection was refined to target CSM-related tests while preserving necessary staking coverage, reverting a previous exclusion to ensure comprehensive validation. These changes improved test reliability, reduced flaky outcomes, and tightened alignment between tests and production parameter logic. Technologies/skills demonstrated: API-based data prefetching, test automation, parameter/bond curve integration, multi-network test configuration, and disciplined commit-driven development.

2025-09 monthly summary: CSM deployment readiness and robust testing were the core focus, delivering documentation updates for the v2 deployment and a comprehensive testing upgrade across the lidofinance repos.
