Measurements & method

Source lines sum the latest snapshot on or before each date for the projects listed below. Each project enters the total at its first measurement. 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.

Weekly churn sums the published devlog diffs across projects. It includes only complete weeks within the trailing calendar year; gaps have no published entry. Diff totals can include files excluded from the source-line count, so they do not reconcile with changes in codebase size.

Source measured with scc 3.7.0. Cache updated Sep 21, 2026.
