The tropicalization count conjecture for bitangents of tropical quartics

Let CC be an algebraic curve over the field of Puiseux series, and let Γ=Trop(C)\Gamma = \operatorname{Trop}(C). Let [Λ][\Lambda] be an equivalence class of bitangents of Γ\Gamma of total multiplicity mm. Bitangent tropicalization conjecture. Then there are 4m4m bitangents of CC tropicalizing to [Λ][\Lambda]. This conjecture proposes a uniform relation between algebraic bitangents and tropical bitangency classes; in the smooth case, the corresponding count of four algebraic bitangents is known, while the statement here concerns the non-smooth setting.
