## Why Remote compaction can process large histories. Repeatedly estimating and replacing the full history, and cloning it when tracing is disabled, adds avoidable CPU and memory overhead. ## What changed - Estimate each history item's token count once, update the total as trailing tool outputs are rewritten, and replace history only after all rewrites are selected. - Preserve unclamped token totals while calculating removed tokens so saturated estimates do not hide overflow. - Snapshot compaction input history only when rollout tracing is enabled. - Reuse the v2 request input instead of cloning it before adding the compaction trigger. ## Testing - Cover enabled and disabled compaction trace contexts through `is_enabled()` assertions.
