  New physics not far above the TeV scale should leave a pattern of virtual
effects in observables at lower energies. What do these effects tell us about
the flavor structure of a UV theory? Within the framework of Standard Model
Effective Field Theory (SMEFT), we resolve the flavor structure of the Wilson
coefficients in a combined analysis of top-quark and $B$-physics observables.
Our fit to LHC and $b$-factory measurements shows that combining top and bottom
observables is crucial to pin down possible sources of flavor symmetry breaking
from UV physics. Our analysis includes the full analytic expansion of SMEFT
coefficients in Minimal Flavor Violation and a detailed study of SMEFT effects
in $b\to s$ flavor transitions.
