Exploit Dev — Stack Frames

We put one function under the microscope and dissect a real stack frame byte by byte: the prologue that builds it, the epilogue (leave; ret) that tears it down, the exact 8 bytes that are the return address at [rbp+8], and how arguments split between registers and the stack. We read it all live in GDB, turn the layout into a single offset with a cyclic pattern, and cover the alignment gotcha that crashes beginners.
