Whether EVERY freshness-tracked leaf under root (root included, hidden
descendants included) holds a commit for view version with a complete
ladder — i.e. whether a re-sweep of the subtree at version would find
nothing to do. false when the subtree has no tracked leaf at all, or any
tracked leaf carries no stamp (never committed): "unknown" never counts as
settled.
Unlike subtreeDisplayProgress this ignores visibility: a hidden eager level
of a nested kind=lod part is still swept, so it must be fresh too.
