During the month, contributed to the keiyoushi/extensions-source repository by delivering a targeted bug fix for the MikoRoku extension. The work focused on correcting the base URL within MikoRoku.kt and updating the associated Gradle configuration, ensuring that the extension routed requests reliably to the intended domain. This adjustment addressed a critical integration issue, supporting stable downstream functionality and improving build reliability. The version code was incremented to facilitate safe deployment and traceability of the fix. The engineering effort demonstrated proficiency in Android development, Gradle, and Kotlin, with clear commit documentation to support future auditing and maintainability of the codebase.
