Registry clock (frame.nowMs) of the outstanding request.
The in-flight activation, if one is running.
The loader passes awaiting the running activation, each of which sweeps
the part's loaders itself once it settles (see
LODGroupRegistry.activatePartitionParts); true is a claim that
cannot be withdrawn. A claim only counts while its pass is alive: a
superseded pass commits nothing, so an activation settling with no live
claim resyncs the part itself. Empty ⇒ started ahead of any pass
(prefetchSlice).
The last activation rejected (its leaves recorded a retryable failure):
the per-frame gate does not ask again until a Retry re-arms it
(LODGroupRegistry.retryLazyChildByNodePath).
A deferred part's activation state (B4).
requestedis set when the per-frame gate asked the loader for a pass to activate it (a pending resync),runningwhile that pass's activation is in flight; both clear when the pass declines it, so a part still wanted is asked for again. A request no pass has reached withinconfig.lod.lazyActivationRequestTimeoutMs(the resync was rejected, or superseded by a pass targeting other parts) expires, and a one-shot wake at expiry lets a parked camera ask again (#2944).
