  Under a stronger genericity condition, we prove the local analogue of ghost
conjecture of Bergdall and Pollack. As applications, we deduce in this case (a)
a folklore conjecture of Breuil--Buzzard--Emerton on the crystalline slopes of
Kisin's crystabelian deformation spaces, (b) Gouvea's
$\lfloor\frac{k-1}{p+1}\rfloor$-conjecture on slopes of modular forms, and (c)
the finiteness of irreducible components of the eigencurve. In addition,
applying combinatorial arguments by Bergdall and Pollack, and by Ren, we deduce
as corollaries in the reducible and strongly generic case, (d) Gouvea--Mazur
conjecture, (e) a variant of Gouvea's conjecture on slope distributions, and
(f) a refined version of Coleman's spectral halo conjecture.
