The sources do not include an accidental over the mordent. In this harmonic context, the use of b is obvious, hence in the main text we add a  over the ornament. Chopin hardly ever put accidentals over trills or mordents in such situations, generally leaving the task of finding the right sound of the auxiliary note to the performer's imagination.

In A (→GE) there are no accidentals in the last group of semiquavers. In the proofreading of FE (→EE) two flats were added, probably indicated by Chopin, a cautionary before A and a necessary one before G.

In A there are no accidentals to the last semiquaver on each beat of the bar – Chopin considered the accidentals written to the earlier notes placed an octave lower to be valid (AsI is slightly more accurate, since it includes a  to c2 in bar 321). In GE1 (→FE,EE) these accidentals were added only just starting from g2, the last semiquaver in bar 321. In GE2 (→FESB) a  to e2 was also added, while in GE3 also a  to c2.
In the main text we give all the omitted accidentals and omit the unnecessarily repeated  to f2 at the beginning of the last R.H. triplet.
There is a similar situation in bars 324-325 and 327-328.

As in bars 321-322, Chopin did not write in A accidentals to the last semiquaver of each beat of these bars. All necessary accidentals were already added in GE (→FE,EE).

In A there is no  lowering g2 to gbefore the 8th semiquaver. Chopin's patent oversight was corrected already in GE1. In such a situation, a  should be added before g3, appearing three semiquavers later at the same pitch, which was not done until in FE (→EE) and GE2.
