FE (→EE) and GE2
..

GE1 has no sharps before the last two quavers. It may correspond to the notation of [A] for Chopin certainly regarded as obvious the sharpening of notes that actually repeat the bass note written with already at the beginning of bar. The error was corrected in FE (→EE), possibly by Chopin, sharps were also supplemented in GE2.

First octave without accidentals in GE (→FE→EE)
Sharps pencilled into FED.
 
..

Chopin certainly regarded the pitch of the recitative's first octave as determined by before the minim b at the beginning of the bar. However, the rules of notation require accidentals before the octave as well, at least before its lower note. The inaccuracy was corrected by Chopin in FED.
