Field notes
The desktop app is intended to watch the game's saves/history folder for finished .run files, with manual file selection offered as another route. The page says manual files are read in the browser, while automatic uploads replace co-op players' Steam IDs with seat numbers before sending. Its sample identifies a real Ironclad Ascension 1 run, seed XDZNK3H5LG, on build v0.99.1; the seed simulator is described as still being built.
