oszuidwest / zwfm-encoder
Software to turn a Raspberry Pi into a production grade audio encoder
oszuidwest/zwfm-encoder holds a health index of 73 out of 100, placing it in the Good band. It scores highest on Vitality (90/100) and lowest on Community & Adoption (24/100). It was last updated today. A single contributor accounts for most of its recent work.
Software health index
Metrics are grouped into weighted categories on one standardized 1–100 scale. Overall starts as their weighted mean, calibrated against the distribution of the public record so bands carry percentile meaning; when public evidence triggers the High-Risk Jurisdiction Policy, the rating is adjusted and receives an At Risk ceiling of 34.
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.
The weighted overall 64 is calibrated to 73 on the published index scale (record calibration 2026-08-02).
Ownership
This repository is backed by an organization — shared, accountable stewardship that can outlive any single maintainer.

Dependency advisories 1
This repository publishes no package the index resolves, so its own dependency graph was assessed — 31 packages, which also include development and test pins that never ship: 1 carry known advisories, of which 1 are direct.
| Package | Version | Relation | Severity | Advisories | Fixed in |
|---|---|---|---|---|---|
| golang.org/x/mod | v0.38.0 | direct | unknown | 2 | 1.27.0-rc.3 |
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.
