b. 128

composition: (Op. 4), Sonata in C minor, Mvt I

Slur to 6th quaver in A, literal reading

Slur to 7th quaver in GE (→FE,EE,IE)

..

The A slur having been led only to the 6th quaver in the bar is musically unjustified. This is confirmed by the comparison with similar figures, e.g. in bar 126. Due to the above, to the main text we adopt a slur led to the 7th quaver, as in GE (→FE,EE,IE).

In the main text we add a  hairpin after the authentic mark in analogous bars 125-126.

b. 130

composition: (Op. 4), Sonata in C minor, Mvt I

Slur to 8th quaver in A (→GEFE,EE,IE)

Slur to 7th quaver suggested by the editors

..

Due to the reasons discussed in the note on bar 124, in the main text we provide a slur whose range we adopt from the remaining analogous bars. We consider the version of the sources, also musically justified, to be an equal variant. The A slur could have been extended by Chopin, yet it is an isolated incident among a few analogous situations.

b. 131-138

composition: (Op. 4), Sonata in C minor, Mvt I

..

As in bars 113-122, in the main text we keep the two-quaver beams present in A. In GE (→FE,EE,IE) they were replaced by standard four-quaver beams.
