App Runtime Verify

Verify a built mobile or app runtime at runtime: run the app (device, emulator, or headless), read the captured runtime output (native logcat, iOS device log, or the Metro/JS console), classify any runtime errors against a per-stack taxonomy, and decide a PASS/FAIL runtime gate for the slice's acceptance behavior. The run's real output IS the Layer-1 runtime evidence (ADR-0048); a claimed-but-not-shown run is unverified. Capability-routed and MCP-agnostic about how the app is run; React Native/Expo (logcat plus Metro) is the first documented adapter. It verifies and routes fixes, it does not apply them. Use after an app slice is implemented to gate runtime behavior the static checks (typecheck, lint) cannot catch. Do not use to plan a screen (use implementation-plan), to write or fix code (use implement-approved-slice), to triage a failure into a fix size (use incident-triage), to verify a Godot scene (use godot-runtime-verify), or with no implemented app to run.
