 ### Verdict
 **PASS** - Plugin host with assembly isolation verified. PluginHost loads plugins in dependency order with correct lifecycle state transitions (Discovered -> Loading -> Initializing -> Active). Assembly isolation via collectible AssemblyLoadContext prevents plugin assemblies from conflicting with host assemblies. Collectible contexts allow plugin unloading and GC collection. Auto-recovery reloads unhealthy plugins when enabled. Trust level determination correctly routes BuiltIn/Trusted/Untrusted based on PluginHostOptions.
