red = douche
I think you are going willy-nilly calling things errors. Graal and its tileset are already bogus and erred.
Some of the proper uses of the tileset are actually not the same methods used in A Link to the Past, albeit the tileset is a ripped and re-worked version of that. It seems that the people who re-worked the tileset to make it higher resolution might have been confused to tackle some of the more technical details, and you know as well as I know that when you truly attept to do cliffing to its fullest potential you will find that particular tiles needed are just not correct or not there for certain contexts.
The tiles needed for this level may exist. But I think the omission of 100% of the tiles necessary to do cliffing correctly means that it is innately ridiculous to assume everyone must tile perfectly using a flawed tileset. You busters are no fun.
