  Recent results from ALICE and CMS show a low-transverse-momentum enhancement
of charm baryon-to-meson production ratios over model predictions based on
$e^+e^-$ collisions. This new development challenges the universality of
fragmentation. We studied the charm-baryon enhancement in collision events
generated by PYTHIA 8 and applied a color-reconnection model beyond leading
color approximation. We proposed a measurement method based on several
event-activity classifiers, to identify the origin of the charm-baryon
enhancement. In this work we extend our studies to a new event classifier,
flattenicity, that considers a broad pseudorapidity range. We have also studied
the role of isospin and strangeness by comparing the production of different
charmed baryons. The observables we explored provide a unique opportunity in
the upcoming measurements from the high-luminosity LHC Run 3 period to better
understand heavy-flavor fragmentation mechanisms, and will help the further
development of models.
