Measurements & method
SCC code lines (nonblank, noncomment) in tracked source files, including tests, SQL, HTML, and CSS. Excludes prose, shell scripts, data/config files, vendored dependencies, build output, generated and minified files. Counts the checked-out tree, not accumulated additions.
Snapshots follow the repository’s default branch. Lines measure codebase size, not work completed. Historical counts can fall when code is removed.
Measured with scc 3.7.0. Updated 2026-10-21.
