Large graph loads periodically stall while the visualizer rebuilds project and galaxy aggregates. Cache project, galaxy and cluster membership using the registry’s append-generation contract, then reuse numeric buffers for centroid and radius calculations. Preserve refresh cadence, moving positions, missing-position handling, ownership changes and existing grouping behavior. Replacing a registry also invalidates snapshots when its revision counters match the old registry.

d2e221635de5ee2f1935c26d87f9aecf0ee282c9:The completed live capture also shows substantial non-periodic tick cost. This change addresses the repeated aggregate work; packaged performance measurement is still required, and no measured speedup is claimed.
