1 person is the primary owner of at least one file in qwenlm/parscale, and test owns the most: 4 files, or 100% of the codebase. The truck factor is 1: that is how few people would have to leave before the majority of owned files lose their owner. 4 files have exactly one contributor, and 1 module is dominated by a single person.
Engineering-leader view of who owns what: silos, hotspots, dead code, and bus-factor risk by person.
