Sum of the visible stamped leaves' committed element counts.
True iff NO visible leaf carries committedLadderComplete: false.
True iff every visible stamped leaf is stamped for version (vacuously
true when version is null — freshness untracked).
Shared leaf type (points / lines / gsplats) or 'mixed'.
Committed energy fraction of the subtree, aggregated as the
reference_energy-weighted mean of the visible non-empty leaves'
committedEnergyFraction stamps (disjoint regions ⇒ L² energy is
additive, so w-weighting makes per-leaf fractions comparable). null
when ANY contributing leaf lacks the energy stamp or its static
level_stats.reference_energy weight — a partially stamped subtree
falls back whole to count comparison (never blend measured and guessed).
Known-empty leaves (count 0) are excluded from the mean, mirroring the
registry's known-empty display guard.
Displayed-quality estimate q = Q·e aggregated like energy, where
Q is each leaf's measured level_stats.quality (its COMPLETE quality vs
its lod group's finest content). null when any contributing leaf has no
measured Q — never blend measured quality with a guessed perfect level.
Purely informational for the layers-panel / data-monitor readouts; the
gate's release rule uses energy alone.
Aggregate committed display state of a subtree's visible stamped leaves.
nodeTypeis the shared leaf geometry type, or'mixed'when the subtree blends types (counts across types are not comparable — the gate refuses).
