If I'm right I would have thought the idea of having garlic and tomato in a base then adding more in the curry pan would have been seen in your 30 years of curry cooking, from my limited experience of 25 years I've not seen much else.
No-one's questioning whether base sauces contain garlic and ginger or tomato paste and no-ones questioning that finished dishes can't contain those same two ingredients either. It is as you rightly point out, pretty standard for most BIR's for both those two things to contain those two same ingredients.
However, your base sauce is
not standard, neither is the way you cook your final dish. However, your base sauce contains the same ingredients (in varying quantities) as most other base sauces. Onions, water, oil, garlic, ginger, tomato paste, whole spices cooked down and blended.
But the way you cook your final dish is quite different to the standard way a final dish would be cooked using a base sauce. You don't fry your garlic/ginger paste or your tomato paste in the same way as at the beginning of more conventional dishes, you merely drop it in the middle of cooking. The question is why? What effect is it having and why are you doing it differently?
Your suggestion that the second addition is not going to cook is, to my mind, incorrect. It does cook out and it does fry; it just happens to have other things there with it - to fry only needs heat and oil; just because it has other things doesn't mean that it won't fry IMHO.
Then you and I have quite different definitions of the term 'fry' and what affect that cooking method will have on the ingredients you're using.
