I think this is the second one, and the first one is the last one. The word order suggests that the not of isn’t is being applied to “just”. When speaking in this sentence, you would likely emphasize the word “just”.

When the first word was intended, the sentence would probably have been simply “This isn’t true in logic. What

No, you cannot omit the auxiliary do in an sentence like If you didn’t have a job what would you do? What would you do if you had not got a job? Is this is incorrect?

Can, however, contract the words did and not into the contraction didn’t, to form the sentence if you didn’t have a job what would you do?

Contractions like did not are very common in spoken English and informal writing. In formal writing, they are more likely to be avoided (opinion differ on whether or not they are appropriate)
