lancaster-university / microbit-dal
lancaster-university/microbit-dal holds a health index of 23 out of 100, placing it in the Critical band. It scores highest on Community & Adoption (56/100) and lowest on Vitality (17/100). It was last updated 830 days ago. A single contributor accounts for most of its recent work.
23
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.
23
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.
Abandonment Policy applies a 60% multiplier to weighted overall health and gives it a ceiling of 49.

Abandonment alert
Work has arrived and nobody has attended to it
no human commit in 830 daysautomated commits excludedpull requests left unansweredissues left unansweredreleases stalledOpenSSF Scorecard reports it unmaintainedOverall rating: At risk ceiling
Silence alone is never the finding — a small, finished library may need no commits for years. This alert requires both: no human commit for a long time, and obligations the project is visibly not discharging. Automated commits do not count as maintenance.

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.

This patch removes such a dependency by rewriting the MicroBitImage\nparsing code so that it directly converts the input string to an integer\ninstead of building a buffer and passing it to atoi().\n\nThis patch saves about 640 bytes of code space and 364 bytes of RAM. It\nalso reduces the amount of stack space used by the MicroBitImage\nconstructor.",

}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 v0.27.0 — full methodology · metrics wiki.
How one result sits in the wider record: aggregate statistics.
