Ayn rand as INFJ? I thought she was a definite INTx? (not that I've really looked much at her). Where is this INFJ typing coming from?
I don't think Je needs to derive from Ji at all, and it's my understanding that they can't really directly interact at all. I also find it strange to identify the "core" of someone with their tertiary function. I generally identify the tertiary as a tool, or backup (inferior too, though there will be an attempt to use it as little as possible) - something used to fill the holes when the top two functions can't do the job, whereas the core of a person is their dom+aux.
Te is certainly a logic-based function (err, depending on what is meant by logic I guess) - it's just externalised logic, rather than internalised. If it doesn't tend towards absolutes, then this is probably because the environment is rarely absolute - but when a near absolute does apply to environmental processes, then Te will adapt to it.
