erweixin / RaTeX
>99.5% KaTeX syntax coverage. LaTeX math renderer in pure Rust. No JavaScript, no WebView, no DOM. One Rust core → iOS, Android, Flutter, Web, PNG. C ABI · WASM · Server-side PNG/SVG.
erweixin/RaTeX holds a health index of 67 out of 100, placing it in the Moderate band. It scores highest on Engineering Quality (86/100) and lowest on Security (41/100). It was last updated today. A single contributor accounts for most of its recent work.
67
overall / 100Software health index
Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At risk ceiling of 49. AI Readiness sits outside the overall score.
67
Excellent85-100Exemplary; meets essentially all checked criteria
Good70-84Healthy; minor gaps
Moderate50-69Acceptable with notable gaps; review recommended
At risk30-49Significant weaknesses; adoption warrants caution
Critical1-29Severe problems (abandoned, single-maintainer, no hygiene)
Score profile
Each axis is a category. The shape matters more than the average — a healthy subject fills the whole shape, while a spike-and-crater profile means strength in one dimension is masking risk in another.
Ownership

This repository is owned by a personal account. A single-owner project carries more continuity risk than an organization-backed one.

}Scores are signals, not warranties. They reflect publicly visible practices on GitHub — not a code audit, and not a security guarantee.
Missing data is excluded and weights renormalized, never scored as zero. Methodology is versioned and open: metrics v1.13.0, schema v0.9.0 — full methodology · metrics wiki.
How one result sits in the wider record: aggregate statistics.
