..

The sources are lacking in the  lowering d2 to d2, which is a patent inaccuracy, repeated almost certainly after [A]

EE1 is lacking in the accidentals before the last semiquaver in b. 59 and the 4th note of the quintuplet in b. 60. These are patent mistakes – cf. the  lowering d2 to d2 in analogous b. 21 – probably committed still in [A], from which they got into EE1 through a proof copy of FE. In the very FE (→GE) Chopin not only added both flats in the last stage of proofreading, but also a cautionary  before d3 at the end of b. 60. All 3 accidentals were also added in EE2.
The same in b. 203-204.

e1 in FE (→GE1,EE)

e1 in GE2 (→GE3), contextual interpretation of remaining sources

..

In FE (→EE,GE1) before the 8th note from the end of the bar, there is no  specifying e1, which must be an oversight. While the semitone chromatic steps in the first part of the figuration in b. 91-92 are built around the f-a-c-e diminished seventh chord, from the 6th small quaver on, the harmonic overtone of the figuration moves towards the fully diatonic key of G major, which is signalised by e2 exposed as the 7th and 13th small quavers. Therefore, in the main text we clearly give e1, which was already introduced in GE2 (→GE3).

..

There is no  lowering G to G at the beginning of the bar in FE (→EE1). This mistake, if committed by Chopin, would prove his anticipatory thinking – modulation to the key of B minor/G major was already determined in the previous bar, hence the use of G could have already been considered obvious (in FE the spaces between the notes suggest that the  before g and maybe even all 3 L.H. flats were added at the time of proofreading). The accidental was added in the remaining editions.

FE are lacking in the  before the 1st L.H. quaver. The patent mistake was corrected in the remaining editions.
