What changed, in the repository’s own words:

This week HEY looked inside 2 of 3 commits to see what changed: 1 changed code, 1 documentation or maintenance only. One code change is enough for the week to count, so HEY stopped there.

Record ship:57fc19fc… · HEY counts it as building; it does not judge the release’s quality or what it means for the token.

Methodology

Public code activity

18/ 100

A reading of the public repositories over 60 days — active days, releases, contributors and how recent — kept apart from Build Momentum.

Days with recorded activity: 1 / 60
Contributors: 1
GitHub releases: 0
Last code update: yesterday

Observed development days. Commit volume is capped and never ranked.

Merged pull requests not measured; the remaining dimensions are reweighted rather than counted as zero.
