What can be considered cannon in Re2R?

I know technically re2r doesnt have two scenarios for each characters with different things happening in the story like sherry being or not infected by birkin in claire scenario or how ada "dies" in leon s scenario. But there are still fewer differences to 1st and 2nd route, like who get first into the rpd, gets to meet marvin, who faces the g5 and those things.

I know If we consider the Re4r the considered cannon scenario is leon A and claire B since in the intro shows leon talking to marvin and the knife he uses in the game is the same that marvin gave to him.

But there are some loose ends like repeated boss fightes and incongruences between leon and claire scenarios, not only we having basically the same objectives but repeated boss fights and events like mr x dying in claire campaingg but technically still being alive till the end of leon s scenario. Or annete dying twice.

Also It still gets me how did ada survive the fall since in re2 she still doesnt have the grappling hook (and would be quite dumb if she had the grappling hook but decided not to use it during her gameplay segment.). I have a feeling that the forgoten soldier of ghost survivors can be considered canon (somehow).

But well what ya consider. To me I have a feeling that the canon is a bit of mix of claire and leon a and b scenarios, even more in order who gets first in the places with few details of scenarios. My head would be like this:

Convenience Store: Claire A and Leon B.

-Being more likely that claire enters first in the store and to be more faithfull to the og re2 intro)

RPD: Leon A and Claire B.

-Due to what we see in re4r. And its claire who faces the G1.

Sewers: Claire A and Leon B

-I think claire Gets to do the sewers puzzles first and leon faces G2

Nest: Claire A and Leon B

-Claire gets first to the nest and open the g cabin for leon (with the pendant). And both faces g3 I guess? I still dunno how to fit that and consider the annete dying twice... The most I can see its maybe she just fainted out in claire scenario

Epilogue: Leon A and Claire B

-I think its Claire who gets the atitude to face g5, and even more feels better using minigun against him than the rocket launcher.

But what would ya consider the most cannon and fitting to re2r:
