Where it stands

Evil Engine finds Portal on its own and reads it the way the game does, in the order its own gameinfo.txt lists: Portal’s archives first, then its share of Half-Life 2’s, then the loose files under both. That’s seven search paths and a little over 34,000 files, and it takes about 20 ms.

Your copy is fingerprinted as two parts, portal and hl2, so a server running Portal’s chambers only asks for those. Every file in both matched Steam’s own checksums.

Known issues

Portal’s gameinfo.txt names an English voice archive that Steam doesn’t install. It’s noted on the mount and skipped.
The order of folders in custom/ comes from a comment in gameinfo.txt, not from the game itself, and hasn’t been checked against the game’s own path command yet.
