./scripts/check-gcm.py dvd.iso Checks the header (DVD magic, game/maker code, title, DOL/FST offsets, apploader), parses the FST, then READS EVERY FILE -- because a dump that lost data still has a perfect header, so structure alone proves nothing. Also reports how much of the image the filesystem accounts for, which is where a truncated or zero-filled tail shows up, and prints SHA-1 for comparison against a reference or a second dump. ⚠️ The zero-run heuristic was wrong in its first form and the fix is the interesting part. Flagging any zero run >= 32 KiB as a dropped transfer gave 7 false positives on a known-good Wind Waker dump, all in Audiores/Stream/*.afc: streamed audio legitimately begins with silence right after its 16-byte header. What a dropped transfer actually looks like is a run ALIGNED to the transfer granularity -- whole 2048-byte disc sectors, because nothing reads or writes a fraction of a sector. Structural silence starts and ends wherever the audio does. So alignment is the discriminator, not length. Sector-aligned runs are now a failure; unaligned ones are reported as structural with that reasoning spelled out. .gitignore: *.iso and *.gcm, so a 1.4 GB dump sitting in the workspace cannot be committed by accident.
