Research direction

Open Cslib/Computability/Languages/OmegaRegularLanguage.lean at line 125 and inspect the proof involving backward.isDefEq.respectTransparency. First reproduce the proof-checking failure with the current Lean environment. Done means the proof elaborates successfully with that API and the file builds.
