The missing accidental before the antepenultimate semiquaver contributes to a certain obscurity concerning Chopin's intention. Although the official rule of validity of accidentals was the same as today, he would often use them as valid not only at their absolute pitch, but also in other octaves. However, in this case E is much more likely than E, hence in the main text we add a cautionary . The legitimacy of this decision is confirmed by the cautionary  before A, added in an analogous situation in the recapitulation, bar 321. EE1 (→EE2) added a  here, changed in EE3 to a .

End of slur in A (→GE)

End of slur in FE (→EE)

The longer slur in FE (→EE) is a result of a proofreading – one can see traces of deletion of the slur repeated from GE1. This kind of change to FE could have been introduced only by Chopin.
