During April 2026, Gaspar worked on the toeverything/AFFiNE repository, focusing on a core bug fix to improve nested list numbering in the front end. Using TypeScript, he addressed an issue where nested numbered lists incorrectly inherited numbering from parent lists by recalculating the context for each list level rather than relying on document order. This adjustment required refining the logic for previous-node evaluation and updating the environment configuration template to support related services. Gaspar validated the fix with before-and-after demonstrations and documented the changes in release notes, ensuring the solution was robust and ready for production deployment.
