## Status
**Pass 3.** All address-derived `Label_XXXX` definitions replaced;
every `jsr`/`jmp` operand symbolic; hardware-register operands resolved
via `apply_symbols.py` (0 residue); audit comments aligned; `make`
stays byte-identical.
`make` assembles `header.s`, `prg.s`, `chr.s`, links them with `ld65` and compares the
result against `rom.nes`:
```
Byte-identical ROM verified.
```
**Pass 3 complete; promoted.** `prg.s` is a traced disassembly with all
address-derived labels replaced, all `jsr`/`jmp` operands symbolic, hardware
registers named via `symbols.inc`, and `apply_symbols.py` reporting 0 residue.
Code coverage: 17,170 / 32,768 bytes (52.4%).
`make` assembles and verifies byte-identical to `rom.nes`.

- **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`.
