Engineering-leader view of who owns what: silos, hotspots, dead code, and bus-factor risk by person.
41 people are the primary owner of at least one file in fastify/fastify, and Matteo Collina owns the most: 124 files, or 41% of the codebase. The truck factor is 2: that is how few people would have to leave before the majority of owned files lose their owner. 113 files have exactly one contributor, and 2 modules are dominated by a single person.
