Or Iz worked on the cairols repository, focusing on harmonizing dependency versions across multiple Cairo crates following a merge. By updating Cargo.toml and Cargo.lock files to standardize dependencies at version 2.8.5, Or resolved merge conflicts and stabilized the dependency graph, which improved build reproducibility and simplified maintenance across different environments. The work required careful use of Rust, Cargo, and Git-based conflict resolution to ensure consistency throughout the project. Although the scope was limited to dependency management rather than feature development, the changes addressed a critical aspect of multi-crate Rust projects by reducing merge-induced failures and supporting long-term maintainability.
