90-day-cliff variant reads 95%–95% across 60/90/180-day activity windows; read the width before the middle value
Squash-merged history: 96% of the commits analysed here collapsed a whole pull request into one commit by one author. Squashing credits a single person for everyone's work and can strip the co-author trailers that name the rest (measured across heavy squashers, roughly a quarter to a third of squash commits still carry them, and those are credited), so for this repository the concentration figures are an upper bound, the bus factors are a lower bound, and the AI-attribution minimum is lower than it would be with the same work merged conventionally. That information is destroyed at merge time and cannot be recovered from the repository, so it is reported rather than corrected. Comparisons against a project that does not squash are comparisons across two different record-keeping systems.

Dark-code ranking

Modules ranked by comprehension risk: the unknown share, amplified by ongoing change and thin ownership. The green meter is living knowledge.

Public-repo caveat: "departed" includes drive-by contributors, overstating attrition relative to a company repo with a real roster. Engagement is a proxy for comprehension. Treat it as a potential indicator rather than a diagnosis.
