In the main text we give the A version with d
1 as the 2nd quaver of the 2nd triplet, along with the cautionary 
added by GE. The natural added by FE (→EE) is almost certainly an erroneous revision, probably introduced in the belief that it is a cautionary accidental after d
2(4) at the beginning of the bar, on a similar basis as the Chopinesque 
to f1, which seems to be reminding that the 
to f2 is no longer valid (actually, Chopin certainly did not warn us of f, which does not fit here at all, but of f, which is likely here – cf. d in bars 224-226 and a in bars 314-315).
