Cycles and self links are refused before Blender is asked; the snapshot's instance scan stops at
100k depsgraph items and says instancesComplete=false (2000x2000 instanced grid: 22 s -> 1.4 s);
the daemon advertisement lists the scene-action and node-graph capabilities. Live: 156 checks pass
on Blender 5.2.3.
