Andres Tarrio enhanced the continuous integration workflow for the rsksmart/powpeg-node repository by upgrading the rootstock integration tests to utilize the latest V2 image within GitHub Actions. This change replaced a commit-based runner with a versioned image, improving the reliability and consistency of test results across local and CI environments. Andres focused on environmental parity and reduced flaky failures by leveraging YAML for workflow configuration and applying CI/CD best practices. The update also improved traceability and simplified future upgrades by referencing the V2 image directly in the rit.yml file, reflecting a targeted and maintainable approach to CI infrastructure improvements.
