Functions

is_app_class

Phase B.9.1 — does this Win32 window class look like an AgentMux top-level window?

is_explicitly_excluded

Phase B.9.1 — explicit excludes for class names that LOOK app-like but should never produce drift. Currently empty because is_app_class is allowlist-based; kept as a hook for follow-up tuning if the allowlist gets too permissive.
