Extension of geometrically constructed wrapped sheaves to the cotangent bundle

Let MM be a manifold and let ΛTM\Lambda\subseteq T^\ast M be a singular isotropic. Nadler's conic cosheaf of wrapped microlocal sheaves is a functor

μShΛw:OpTMstω.\operatorname{\mu Sh}_\Lambda^w:\operatorname{Op}_{T^\ast M}\rightarrow \operatorname{st}_\omega.

Its restriction to the zero section is the cosheaf ShΛc\operatorname{Sh}_\Lambda^c of wrapped sheaves, while the geometrically constructed wrapped-sheaf cosheaf is denoted by wshΛ\operatorname{\mathfrak{w} sh}_\Lambda.

Extension conjecture. The construction wshΛ\operatorname{\mathfrak{w} sh}_\Lambda should extend from the zero section to the cotangent bundle TMT^\ast M.

The paper explains that Corollary of its main theorem identifies the two wrapped-sheaf cosheaves on the zero section. The proposed extension would provide a geometrically constructed counterpart to Nadler's categorical cosheaf of wrapped microlocal sheaves.
