The legally-owned BFM USA BIN/CUE dump is at /mnt/z/Storage/git/BFM-decomp/Brave Fencer Musashi (USA)/ (Windows Z:\Storage\git\BFM-decomp\Brave Fencer Musashi (USA)). Drew corrected me here on 2026-06-13 after I guessed a wrong /mnt/z/Games/Emu/... copy.

• Track 1 ...(Track 1).bin = 364,846,944 B — the MODE2/2352 data track holding the ISO9660 volume + every .CD file.
• Tracks 2–4 are CD-DA AUDIO (each (Track N).bin = 150-sector INDEX 00→01 pregap + audio). The 3 .DA ISO files (ST01_13A.DA=Track2, ST01_13B.DA=Track3, DUMMY_DA.DA=Track4) point into them.
• Scope change 2026-06-13 (Drew): stage ALL 4 tracks + the .cue to ext4 disks/, and extract the .DA files too. extract.py extracts them as raw 2352-byte/sector audio (sizes differ from the 2048-based ISO entry). Supersedes the earlier "Track 1 only / .DA out of scope" plan.
• Per H2 the dump is read once, not built against — copied to ext4 disks/ (gitignored) for fast iteration instead of reading repeatedly over the slow 9P /mnt bridge.
• The raw dump is never committed (gitignore firewall, survives even the H1 relaxation in rom-content-git-policy).
