  Considerable information about the early-stage dynamics of heavy-ion
collisions is encoded in the rapidity dependence of measurements. To leverage
the large amount of experimental data, we perform a systematic analysis using
three-dimensional hydrodynamic simulations of multiple collision systems --
large and small, symmetric and asymmetric. Specifically, we perform fully 3D
multi-stage hydrodynamic simulations initialized by a parameterized model for
rapidity-dependent energy deposition, which we calibrate on the hadron
multiplicity and anisotropic flow coefficients. We utilize Bayesian inference
to constrain properties of the early- and late- time dynamics of the system,
and highlight the impact of enforcing global energy conservation in our 3D
model.
