 ## Status
 
-**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.
+**Pass 1.** The project builds and verifies byte-identical to the
+original ROM. `prg.s` is a traced disassembly classifying bytes as
+reachable code or data, with every instruction carrying a trailing
+audit comment. Unreached bytes remain as explicit `.byte` blocks; no
+ROM byte is deleted or reformatted.
 
 `make` assembles `header.s`, `prg.s`, `chr.s`, links them with `ld65` and compares the
 result against `rom.nes`:
