SPP, show me the error in this proof given 1/3 = 0.333...

I've seen SPP agree in multiple places that 1/3 = 0.333... and that 1/3 * 3 = 1 by what SPP calls "divide negation." I've also seen SPP agree that 0.333... * 3 = 0.999... but somehow still finds that 0.999... ≠ 1. SPP, I will provide what you'd consider a false proof below, and I want you to say where I made any mistakes.

1 = 1/3 * 3 (1) (This is "divide negation.")

= 0.333... * 3 (2) (You've agreed to this previously.)

= 0.999... (3) (You've also agreed to this.)

∴ 1 = 0.999...

SPP, I want you to identify the line(s) with an error. However, based on what I've seen you say in other places, I don't see where you could say that there is an error. To make what I'm asking clear, TELL ME THE LINE(S) WITH AN ERROR. I'm not looking for some explanation on why you think 0.999...≠1; I'm looking for you to tell me where I went wrong in this particular proof my telling me the line number and why what I did in that line is wrong. You should not be bringing nonsense about 0.999... or 0.333... growing endlessly or how 1/10^n is never 0.
