The cluster page and the console say which picture and 3D models are here, and add them

A site whose catalog had no flux-schnell or triposr showed no Images or 3D
page, and nothing said they were one click away. The cluster page now has
a Pictures and 3D models card under the models: each preset, what it
makes, the classes of card here it fits, whether and by whom it was
added, and why the leader has not added it by itself; an Add button, which
says first when it would install ComfyUI on the GPU nodes and restart the
control planes; and the switch for presets.auto. The console's models
screen shows the same under its table: A adds one, asking first in the
same case, and P turns automatic adding on or off.

`ctl model add PRESET` and `ctl model presets` go through the presets API,
so the control plane keeps who added one, and `ctl model presets auto
on|off` flips the setting; against a control plane from before, add sends
the entry as v0.14.4 did.
