- gruneis2014: Vertex corrections for GW

## Coverage Assessment
Method: GW approximation. Regime: weakly to moderately correlated. Dimensions covered: GW formalism, self-consistency, vertex corrections.

## Overall Verdict
Sources sufficient for qsGW improvement study. Missing: explicit DMFT+GW combination paper, but deferred to L1 reading.
