In March 2025, Gawnieg focused on backend development and testing for the argotorg/sourcify repository, addressing stability issues in the Sourcify test environment for the Happychain Testnet. By updating the contract address and chain ID to align with the new Happychain Testnet, and removing the deprecated 'partial' verification type, Gawnieg streamlined the test configuration process. This targeted bug fix, implemented in TypeScript, reduced test flakiness and improved the reliability of continuous integration validation. The work demonstrated a methodical approach to maintaining test infrastructure, emphasizing code maintainability and efficient validation cycles rather than feature delivery during this period.
