Editorial
Editorially important is a fourth, separate channel.
No editorial picks this week: an editorial item exists only when a named editor (human or the responsible AI editor) writes one.
Ranks and numbers freeze when the edition is published and are never recomputed with later numbers. Star counts come from GitHub's API at the recorded times and are popularity signals, not quality rankings. Repository names and marks belong to their owners; GitHub is the source platform.
