What load_and_run() actually does (phases 0-2)
I been through the fire and the rain, and I came out the other side
Posts 3 and 4 gave the high-level overview of the load pipeline—flush, load, flush again, verify, launch. This deep-dive series rips open the actual Python and walks through the code. We’re starting with phases 0 through 2 of load_and_run(), which covers everything up to but not including the XOR verification passes.
