Paul wrote X.

Paul wrote as to what was Scripture, not about 'other' writings which were not ---

Then centuries later Jerome wrote Y

And in that, Jerome agreed with Paul.

Therefore Paul did not write X

No, therefore Paul did not write according to your own assumption, which would be to have been including what Jerome referred to as Apocrypha.

The logic is just blistering.

Paul wrote as to what was Scripture

He did. And he wrote: "all that thou knowest since thy infancy is inspired by God". In Greek. Same language as Septuagint.
