Eigenvariety and trianguline deformation space component conjecture

Fix a prime qpq\neq p splitting in EE, choose qq' as in the source, and let GG be a unitary group in dd variables attached to E/QE/\mathbb{Q} satisfying the stated conditions at infinity and at finite places. Let π\pi be an automorphic representation of GG with the stated ramification, supercuspidal πq\pi_q, unramified πp\pi_p with dd distinct Satake-parameter eigenvalues, and let YπY_\pi be the minimal eigenvariety containing π\pi. For the associated residual representation ρˉ\bar\rho, classical point zYπz\in Y_\pi, and trianguline deformation space X(ρˉ,z)X(\bar\rho,z), assume that ρˉ\bar\rho is absolutely irreducible, the Hodge--Tate weights k1<<kdk_1<\cdots<k_d are pairwise distinct, and ρπGp\rho_\pi|_{\mathcal{G}_p} is non-critically refined. Eigenvariety component conjecture. The map

Yπ(ρˉ)X(ρˉ,z)Y_\pi(\bar\rho)\longrightarrow X(\bar\rho,z)

is an inclusion of irreducible components of X(ρˉ,z)X(\bar\rho,z). This is a geometric comparison between an eigenvariety and a trianguline deformation space; the source presents the claim as a conjecture and gives no resolution.
