“It’s” at the end of a sentence [duplicate]

The word it’s seems to be a good substitute for it is. Yet it doesn’t sound correct to substitute it’s for it is in: “That’s just the way it is.” To make it: “That’s just the way it’s.”

Is it grammatically correct to make that substitute? And why doesn’t it sound correct? Is there any instance where the word it’s sounds correct and is grammatically correct at the end of a sentence?

The discussion in the answer to Is there some rule against ending a sentence with the contraction "it's"? does not seem to be on point because the premise of that answer is that "it is" at the end of the sentence has a stranded object, but it doesn't. Here the second "it is" has its distinct meaning precisely because there is no object. See first OED definition of "Be": 1 "Without required complement: to have or take place in the world of fact, to exist, occur, happen."

Can't find an authoritative source, but I believe that the contraction "it's" can't be used when "it is" is used its existential form without a complement. See first OED definition of "be": "1. Without required complement: to have or take place in the world of fact, to exist, occur, happen."

For example, "It is what it is" can't be stated as "It is what it it's." (But, you can say "It's what it is," because "what it is" is the complement for the first use of "it is."

This seems to hold for all of the contractions of "to be" (I'm, you're we're, they're, etc.)

"I think therefore I am." Not "I think therefore I'm."
