Module 2 : Re-Engineering and Verification Workflow

Module‑1 showed you that LLMs are not magic but a composition of code, math, and hardware, all reachable from Python if we know where to look. It traced how LLMs sit in the stack: Python as glue, PyTorch as the modeling layer, and hardware‑specific backends (CPU, GPU, etc.) as the execution engines.
