Generation-stamped snapshot returned by World::observe_dirty().
Pass it to World::clear_dirty_observed() after rebuilding derived state. The clear succeeds only if no later dirty mark changed the content version, so a maintenance pass cannot erase intervening marks.
residency_generation scopes the observation to one residency interval. A sparse world restarts a rematerialized chunk's content version at zero, so content version equality alone would let an observation taken before an eviction match a mark made after rematerialization and clear work it never saw. Always-resident worlds never evict and leave this invalid on both sides.
