Relation to other work
(1) General properties of geometric extension algebras and formality statements
in the context of (-adic) sheaves
have been discussed in the literature extensively, see for example [Sau13], [Kat17],
[McN20] and [PB19].
(2) Formality results in the context of perverse sheaves can be found e.g. for graded affine Hecke algebras in [Rid13], [RR16] and [RR21] and related to quiver Hecke algebras in [McN17] and [Web19].
