JWST spectra of EC 53 indicate CO fundamental and H2O bending absorption weaken by ~2 during burst due to continuum dilution, with relative veiling yielding hot-continuum ratios of 2.9 and 1.71 and viscous-disk accretion-rate ratios of ~3.6 and ~2.0.
Microlensing-inferred free-floating planets plus bound planets require more mass than protoplanetary disks supply, even at 100% conversion efficiency, potentially creating a crisis if the mass function is bottom-heavy.
Halos in Elias 2-24, IM Lup, and DM Tau hold 20-30% of total dust mass with cm-sized grains, helping resolve the disk mass-budget problem even though drift and growth timescales are shorter than disk ages.
This review chapter discusses open questions on protoplanetary disk substructures and how SKA-Mid continuum observations at 12.5 GHz can help resolve them.

Dust characterization of halos: The extended emission in protoplanetary disks
Halos in Elias 2-24, IM Lup, and DM Tau hold 20-30% of total dust mass with cm-sized grains, helping resolve the disk mass-budget problem even though drift and growth timescales are shorter than disk ages.
