Pass 0 skeleton. The project builds and verifies byte-identical to the original ROM, but no disassembly exists yet: prg.s is a single .incbin "prg.bin" of the PRG image.

make assembles header.s, prg.s, links them with ld65 and compares the result against rom.nes:

Byte-identical ROM verified.

Open work

Pass 1 - run nesdis.py over prg.bin to produce the code/data split. The tracer reads the vectors from the last six bytes of the PRG image, so the split seeds correctly.
Pass 1 must emit the canonical audit comment ; CPU:$C123 PRG:0123 AD 21 03 at column 35 for every instruction.
Pass 2 - replace the address-derived Label_XXXX names and the raw $XXXX call operands.
Pass 3 - semantic zero-page aliases (applied only at the sites where their role is proven) and named data tables.
Promotion to NROM/<name>/ once Pass 3 is done, as git mv.
