Share indexed recency, count/weight budgets and native disposal across six caches while preserving domain invalidation and eviction policies. Keep pools, weak memos and dependency-owned resources separate.\n\nAccount for effect pixels incrementally and preserve caller ownership on rejection. Validate disposal, slot reuse, exact integer accounting and unchanged raster output.
