Walkthrough

Debugging and validation enhancements were made to kernel process management. A new function, CheckPid0Magic, was introduced to monitor the security token's magic value for the idle process at critical points. The SecurityToken structure was packed, checksum calculation was made field-wise, and process slot initialization was improved for consistency and security.

Changes

File(s)	Change Summary
Kernel/Core/Kernel.c	Added two CheckPid0Magic calls in KernelMain after process initialization and security manager creation.
Kernel/Process/Process.c	Added CheckPid0Magic function, revised SecurityToken checksum logic, improved debug output, and slot clearing.
Kernel/Process/Process.h	Marked SecurityToken as packed and declared CheckPid0Magic function.

Poem

A rabbit hops through kernel code,
Checking magic where secrets are owed.
Tokens packed tight, checksums anew,
Debug prints shining, process slots too.
With every hop, security grows—
In fields and flags, the magic shows!
🐇✨
