Building on the scaffolding constructed in the first two articles in this series, we now proceed to the geometric phase of our sheaf (-complex) theoretic quasidualization of Kubota's formalism for -Hilbert reciprocity. Employing recent work by Bridgeland on stability conditions, we extend our yoga of -structures
situated above diagrams of specifically designed derived categories to arrangements of metric spaces or complex manifolds. This prepares the way for proving
-Hilbert reciprocity by means of singularity analysis.
