## Summary - When `cleanExpiredMetadata` is enabled, skip scanning all snapshot manifest lists to collect reachable partition spec IDs if the table has only a single spec that is the current default spec (the common case). - Additionally, once all known specs have been confirmed reachable during the scan, skip manifest I/O for the remaining snapshots. Both optimizations avoid unnecessary manifest file reads for tables with few or no partition spec evolutions. ## Test plan - [x] Existing `TestRemoveSnapshots` tests pass (covers `testRemoveSpecDuringExpiration`, `testRemoveSpecsDoesntRemoveDefaultSpec`, `testNoSchemasOrSpecsToRemove`) - [x] `./gradlew :iceberg-core:spotlessCheck` passes - [ ] CI validates no regressions across all test suites 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
