A profile's contents: block and a DAT both state, per set, the members one emulator version expects. Torrentzip makes archive bytes a function of that list alone, so a recipe plus the roms reproduces the archive exactly. MAME ships its -listxml as a release asset and FBNeo keeps its dats in its repository, so neither needs a browser. The importer streams the 311 MB document with a sliding window, resolves romof parents in two passes, drops undumped members, and accumulates versions instead of replacing them. Identical recipes shared across versions are stored once with dats listing every version that agrees: 22 MAME versions give 23679 entries for 1726 distinct recipes, 18 MB down to 2.2 MB. Snapshots live in recipes/ because load_provenance_snapshots reads every provenance/*.json as a dump catalogue, and a recipe is not one. 1113 archives now reproduce byte for byte, against 175 from profiles alone, and spec128.zip is rebuilt from roms already held.
