 ## 1. Purpose
 
-WhiteMagic is a .NET 8 library for Windows.
-The library reads and writes the memory of another process.
-The library also injects code, hooks functions, and calls remote functions.
-The target process is a game client or any modern game.
-The target CPU architecture is x84 or x64.
+WhiteMagic is a .NET 8 diagnostic library for Windows.
+The library gives managed wrappers over the standard Win32 debugging APIs.
+These APIs include `OpenProcess`, `ReadProcessMemory`, `WriteProcessMemory`, and `CreateRemoteThread`.
+Debuggers, profilers, and modding tools use the same APIs.
+Examples of comparable tools are Cheat Engine, ReClass.NET, and x64dbg.
+
+The consumer of the library is a modding and automation client.
+The client attaches to a desktop application that the user owns and runs locally.
+The reference application is a legacy game client (WoW 3.3.5a).
+The target CPU architecture is x86 or x64.
+
+The library is a general-purpose interop layer.
+It does the same class of work as a debugger extension:
+read and write memory in an attached process, marshal managed types to raw bytes,
+generate small trampoline routines, and invoke routines in the attached process.
+All operations need the same access rights that a debugger needs.
+All operations run on the local machine with the consent of the user.

 ## 9. Scope limits
 
-- Do not add game offsets to the library. The consumer holds the offsets.
-- Do not add bot logic to the library.
-- Do not add anti-cheat evasion.
+- Do not add application-specific constants to the library. The consumer holds the offsets.
+- Do not add automation or gameplay logic to the library. The library stays a general interop layer.
+- Do not add concealment logic. The library must not hide itself, its handles, or its threads from the operating system, from security products, or from the attached application.
+- Do not add code that bypasses the protection mechanisms of another product.
 - Add the optional Iced backend only behind the `IAssembler` seam. Keep the default backend free of a third-party dependency.
