libjxl / jxl-rs

When each star and fork was added, collected from GitHub and bucketed by day. Cumulative growth sits directly above the daily additions it is made of, so the two read against each other: steady organic accretion looks nothing like an abrupt, short-lived burst. Where that difference is measurable, it is reported as growth authenticity.

Each point covers 5 days.

Full resolved dependency set from the GitHub dependency graph: 39 direct and 155 indirect (transitive) packages. The transitive closure is complete when the repository commits a lockfile.

This repository publishes no package the index resolves, so its own dependency graph was assessed — 167 packages, which also include development and test pins that never ship: 5 carry known advisories, of which 0 are direct. 27 could not be assessed — no resolved version, an unsupported ecosystem, or beyond the reported package list.

An advisory means the version recorded in the dependency graph falls inside an advisory’s affected range. Reachability is not analysed, and the graph includes development and test pins — a finding may concern tooling rather than shipped software.
