methodology

Fix-labelled changes, file change frequency, ownership concentration and maintenance cadence, each computed from this repository's analyzed commit window. None of them is derived from stars, which is why they are allowed to disagree with the curve above.

Notes on apache/lucene

How many stars does apache/lucene have?
GitHub currently reports 3,557 stars for apache/lucene. The chart itself is rebuilt from historical star data, which records star actions and not unstars, so it reads as an attention signal rather than a net star count.
What does recent star activity look like for lucene?
gitdebt observed about 6 public star actions for apache/lucene over the latest 90 days of archive coverage (about 6 in the latest 30). This is an approximate attention signal, not a net-star count, because unstars are not present. That's below its lifetime average activity pace, which is common for mature projects.
Is lucene still active?
Public archive data shows about 6 star actions for apache/lucene in the latest 30 days of coverage. For repository activity, use the commit heatmap, commit trend, and contributor charts on this page.
When was lucene created?
apache/lucene was created on February 23, 2021. The first public star activity observed for apache/lucene is from Mar 2021.

Light and dark variants, alt text, and one provenance line. Provenance is text in your README, never baked into the image URL, so the chart stays cacheable.

Paste it into Claude Code, Cursor, Codex, or any coding agent with your checkout open. It carries the measured numbers, the exact snippets, and the rules — including replacing an existing star-history widget in place rather than stacking a second chart under it.
