As an outsider to the field that what I understood from the person you are replying to. What's the difference ?
1) The code and the comments disagree.
2) The code passes the tests.
3) The comments promise functionality the code does not implement.
The first post was "It doesn't meet the business requirements the comments indicated, so the software is broken." The replying post was "Actually, the business requirements were faithfully turned into tests, so the software is fine. The comments need to be rewritten"
"The Lean code merely tells us that the theorem is correct, yet the NL proof with intermediate arguments, lemmas and results may be incorrect or have incorrect arguments."
A: "In particular, we show that the formalised Lean proof does not correspond to the NL proof of blow-up of solutions to the Navier-Stokes equations."
B: "No, they're not claiming that [...] The authors are claiming that the Lean proof is not the same proof as the NL one"
The question was: what's the difference between A and B?
Your answer to that question was "This paper says the NL proof does not match does not match the lean proof".
It seems to me like A is the exact same thing as B, and you are here claiming that they're different things while merely repeating the same claim that was already claimed in both A and B.
A: The English language description doesn't do the same thing as the code the AI wrote.
B: The English language description doesn't do the same thing as the code the AI wrote.
A and B are the same; there is no difference. Is this what you meant? Or did you mean the opposite of this? If you meant the opposite of this, what exactly is the difference?
