During December 2024, Marton Sarosi developed and delivered the initial project asset packages for the kizsi2024/12K-SZ repository, focusing on onboarding and repository readiness for Scratch-based projects. He introduced binary Scratch assets, including Chat_Python.sb3, My Project.sb3, and ai.sb3, and committed these as a reproducible starting point for new contributors. Using Git for version control and working with Scratch’s .sb3 format, Marton established a structured approach to asset management. This work enabled rapid project kickoff and reduced setup time, but was limited in scope to asset initialization, without addressing bug fixes or deeper feature development during the period.
