PlatformCop

The PlatformCop detects code that is technically broken, dangerous, or silently ignored at the AL platform level. It flags constructs where the runtime behaves differently from what the developer likely intended. Unlike the ApplicationCop, which focuses on Business Central application conventions, PlatformCop targets AL platform and runtime correctness regardless of the application context.
