?? "walking section over (basic?) toric open u" toric quasicoherent sheaf as having its pullback squares (?? ...) also be pushouts (basic / affine case .... ??? as especially trivial ???? .... ( ??situations where square are pullback / pushout because two parallel sides are invertible ... ?? ...) ... ??? other cases ??? .... ???? ....) and thus also interpretable as toric quasiherent cosheaf ?? ... ???? ..... ??? ....

?? toric / non-toric analogy ... ??? ....

?? pushout condition ... ??? but also extra "flat"ness .... ??? might this end up implying pullback condition too ?? ... ???? .... ?? or ... ?? in basic / affine case, maybe even more straightforward ... ???
