## What - Skip manifests that cannot contain partitions in a dynamic overwrite. ## Why - Planning currently reads entries for unrelated partitions. - Java uses manifest summaries to limit this work. ## Implementation - Use the current-spec partition projection and existing summary evaluator. - Keep manifests when summaries are missing or inconclusive; preserve older-spec files. - Skip the table-wide duplicate-path scan for Arrow files with generated UUID paths. Keep it for prewritten files. ## Benchmark - **1 of 256** synthetic manifests selected; summary filtering took about **34 µs/op** (Apple M1 Pro).
