We study constructible sheaves on a topological surface with singular support prescribed by a legendrian knot in the unit cotangent
bundle. As we explain, moduli spaces of such include the wild
character varieties which parameterize connections with irregular
singularities, but also many more spaces. We explore connections to
known constructions in legendrian knot theory, to Khovanov-Rozansky
knot homology, and to the P=W conjecture in nonabelian hodge theory.
