Worked on stabilizing source map debugging within the webpack/webpack repository, focusing on resolving a bug that affected the integrity of injected debugId values when using the hidden-source-map option. Addressed the issue by ensuring the debugId was correctly formatted and reliably included in the generated source maps, which improved the accuracy and reliability of debugging for developers. Utilized JavaScript and in-depth knowledge of source map internals to implement the fix, emphasizing disciplined code hygiene and clear commit messaging. This contribution reduced debugging time and enhanced toolchain stability, supporting maintainability and productivity for the broader webpack developer community.
