-===================================
-# 0: General Information
-===================================
-
-- **Programming Language**: C / C++
-- **Build System**: Make / BTB (Build the Build)
-- **Purpose**: System Call Interface (SCI) for NeKernel
-
-===================================
-# 1: How It Works
-===================================
-
-- This header provides the raw API surface for accessing NeKernel's system calls.
-
-- It is **not** directly used by applications.
- - Instead, it is abstracted by the **SystemSDK**, which presents a stable, high-level interface.
-
-- At runtime:
- - System calls are routed from user-space code to the **kernel syscall manager**.
- - The syscall manager executes the requested operation and returns control to `libSystem`.
- - Finally, the result is delivered back to the originating process.
-
-- This separation ensures that:
- - The SCI remains low-level and close to the ABI.
- - `SystemSDK` provides portability and shielding from changes in syscall internals. \ No newline at end of file
