Review findings for this part

The findings come from ../../findings/ (pass 1). The script matches them to this part by source line.

ID	Severity	Evidence	Status	Location	Problem
D04-M2	major	KNOW	open	L432	The table row says “NASM / WASM — Netwide Assembler…”. NASM and WASM (the Watcom assembler) are different tools. The description covers only NASM.
D04-M3	major	KNOW	open	L445	The page says “DOSBox-X / 86Box — Cycle-exact”. This is not true for either tool in the strict sense. DOSBox-X is clearly approximate.
