We add cautionary flats before the 1st octave. The signs were introduced already in GE2 and EE2.

b. 125

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

There are no accidentals before the last R.H. octave in GC & FE1 (→FE2EE1). The necessary  restoring c1 was added while correcting FE3 (→FE4). In GE and EE2 naturals were added before both notes of the octave.

b. 126

composition: Op. 35, Sonata in B♭ minor, Mvt I

b-b1 in GC (→GE)

b-a1 in FE (→EE)

..

GC (→GE) has a b-boctave as the 4th quaver in the bar. The comparison with the motifs in the adjacent bars (as well as in bars 133-135) almost certainly indicates a mistake of the copyist.

b. 127

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

GC and FE1 (→FE2EE) lack in the accidental before the 3rd crotchet in the L.H. Patent in this context Chopin's mistake was corrected in GE and FE3 (→FE4). Moreover, FE1 overlooked the  before the 4th note.

b. 128

composition: Op. 35, Sonata in B♭ minor, Mvt I

g2-c3 in GC (→GE), FE3 (→FE4), FESch & EE2

g2-e3 in FE1 (→FE2EE1)

..

The version with e3 present in FE1 (→FE2EE1) (in both FE without the necessary  in this situation) is almost certainly erroneous. It is proved by: c3 written in GC (→GE) and the Chopinesque corrections in FESch and FE3 (→FE4). The correct version with c3 is written inaccurately in some of the sources – the necessary  is only in GE and EE2. Further omissions of accidentals – see the adjacent note.
