  "suggested_fix": "Run the probe on a guest that provides the documented stack: a distro with GTK 4.22, libadwaita 1.9 and glibc 2.45 (or newer), or use the README 'Flatpak Nightly' route (flatpak install dev.boxxy.BoxxyTerminal), which ships its own runtime. Then re-run the install, followed by boxxy-agent --version. Not attempted here: flatpak runtime download and a session D-Bus, which are larger than this smoke task. Source-level repo changes would not fix this, since the v4_22 GTK feature is intentional and the agent is linked to GTK via boxxy-preferences and boxxy-model-selection. Source is unchanged."
