You have never expressed any disagreement with the starting points of
Tarski's proof. You have ever claimed that any of Tarski's inferences
were not truth preserving. But you have claimed that the last one of
these truth preservin transformation has produced a false conclusion.

Tarski's proof was not about provability. Gödel had already proved
that there are unprovable true sentences. Tarski's work is about
definability.

Step (3) is self-contradictory, thus his whole proof fails.

 Irrelevant. As Traski clearly points out, (3) can be derived from (1) and
(2) with a truth preserving transformation.
