OptionalsignalPer-update abort signal forwarded to loader.updateView (see DataLoader).
OptionalframePer-tick LOD time budget during dimension-animation playback (see
ViewState.frameBudgetMs). Injected into the DERIVED per-node view state
only — a per-pass directive, so refinement/retry passes (which derive
independently) stay budget-free.
OptionalladderPinned playback ladder depth (see ViewState.ladderDepth). Same per-pass
contract as frameBudgetMs: injected into the DERIVED view state only.
Passes run so far — gates the first-update
[GEOM]logs here and in the data processor (the view version does not move on a same-view pass).
