Description

Versions published since 2026-07 contain a stub 'share compute swarm' functionality for 'faster results'. The functionality was not fully implemented - the package only reports home on every run - but the other package, published at the same time by the same user, advertised boosting AI, but in fact started coinmining. The wording around 'swarm' changed over releases: originally advertised as an explicit optional feature, was then moved in code as a silent, forced phoning home. Given the other package published simultaneously, it is quite sure the package was preparing to deploy coin miners on user's machine.
