FCI
compare
b. 25
The version of FCI featuring d1 (uncertain interpretation), hence perfect and not flatted fifth of the G7 chord, is naturally earlier and had already been abandoned by Chopin when A was being created (nothing points to an overlooked – in the entire fragment, accidentals were inserted unusually meticulously; there are no oversights in this bar).
