During March 2026, Queelius focused on stability and correctness across three repositories by addressing subtle bugs rather than adding new features. In PRQL/prql, Queelius refined the SQLite integer division logic using Rust and SQL, ensuring accurate results for edge cases where dividends are smaller than divisors. For apple/swift-nio, Queelius improved error handling in Swift by mapping EPERM errors to permissionDenied, enhancing clarity in user-facing error messages and adding targeted unit tests. On Automattic/harper, Queelius resolved a persistence issue in the Svelte-based Select component, switching event bindings to ensure toggle states are reliably stored, thereby improving front-end reliability.
