Four libs written in one pass rather than four sequential splits, which is what stops the libs chaining - the entry gets one source block naming all four and no lib sources a sibling. steam_compatibility.sh is reverted and stays at 663. Its CACHE_MAP associative array is declared and filled in what would be the ProtonDB lib but read by main, so that lib fails SC2034 linted alone. Third file deferred for the same reason: shared mutable state means the seam is not there.
