During this period, contributed to the decentraland/adr and decentraland/js-sdk-toolchain repositories by enhancing governance and testing processes. Improved the Architectural Decision Records lifecycle to a living format and expanded ADR-239 with practical examples and clarifications for avatar assembly, getHides, forceRender, and wearables coverage, using Markdown and TypeScript for documentation and technical writing. In parallel, re-enabled and updated snapshot testing in JavaScript to reflect minor changes in compiled code size and memory usage, supporting performance tracking and test reliability. These efforts streamlined onboarding, clarified standards compliance, and strengthened the foundation for ongoing development and release confidence across the codebase.
