Try again to get this at the bottom.
Let me put this at the bottom of the discussion, where I hope it will be noticed.

Signal may be “hunch”, “indication”, “possibility”, or “suspicion”.”
What I am saying is much simpler than you are making it out to be. If there is a CO2 signal in the temperature/time graph, then it should be possible to calculate the climate sensitivity of CO2 directly from this signal. No such calculation has been made. There is no CO2 signal. It is as simple as that.
