// What this guard exists for: calendar and contacts moved from an app-store entry to CORE on
// 2026-08-19. A fresh install gets `radicale` from machine-setup and `officer-caldav` from
// CORE_PROCESSES. An existing one gets NEITHER from `git pull`, because a pull changes nothing outside
// the repository — so /calendar would mount, render, and talk to nothing.
//
// The install side is deliberately not tested here: it shells out to a package manager, and a test that
// really ran `apt-get install` would be a test that modifies the machine running it. What IS worth
// pinning is that the detector asks the same question the sidecar will ask.
