Commits
1,211 first-parent commits on main in the window, lockfiles and build output excluded. Median 115 lines, p90 605, 207 over 400 lines, p90 8 files per commit, churn proxy 12%.
How this was measured
Over-engineering is five patterns counted per thousand lines, parsed with go/types and tree-sitter rather than matched as text. Test coverage is logic files against whole-word mentions of their symbols in the test files beside them. Commit health reads git log --first-parent over the window, with lockfiles and build output excluded. The composite renormalises over whatever could be measured; anything that could not says so.
