The original worker was terminated due to a usage limit. Astra resumed the work and verified it locally. The game.details CRC32 matches 26 original file paths / 21 distinct contents. Six stale map start lengths were reproduced and fixed. Identity and longer/shorter roundtrips are byte-exact; negative controls detect false lengths despite valid DAT hashes and stale CRCs.
