summary

Researchers mine MAINTAINERS and git history to build a section graph where vertices are maintainer sections and edges mean shared lines of code; they run walktrap clustering on the top 20 sections to detect de-facto subsystems, measure conforming integration (whether relevant maintainers merged a patch), and find concrete mis- and non-conforming examples inside DRM and media clusters. Results feed safety-certification evidence for ELISA and are reproducible via tools on GitHub at lfd/pasta.
