    State why the set moved forward rather than the core moving back.

    summarywrap

    requirements.txt pinned plugina 2.0.0 (needs libcore 2.x) alongside pluginb 1.0.0 and libcore 1.4.0 (both 1.x), which is unsatisfiable. app.py calls plugina.slug and pluginb.export_with_ids, which exist only in the versions built against the 2.x core, so the resolution was to move the whole set forward: plugina 2.0.0, pluginb 3.0.0, libcore 2.1.0. check.sh passes and only requirements.txt changed.
