February 2025: Key reliability improvement in SAP/ui5-linter. Implemented deterministic lint message ordering by sorting lint messages by line and column, ensuring consistent outputs across runs. Extracted the sorting logic into a reusable utility function for maintainability and reuse. Commit 4964fd0f4cca694456b429870d8b3d25874a882f implemented the fix. This work reduces CI flakiness, speeds up debugging, and demonstrates strong refactoring and modular design skills in JavaScript/TypeScript within SAP/ui5-linter.
