## Summary When a windowed changelog ends with a transaction control record, the restore consumer filters that record from poll results. Probing only `endOffset - 1` therefore returns no record and incorrectly abandons the retention-based restore optimization. This change retries the probe from the preceding offset before falling back to the beginning. The regression test covers both a visible latest record and the filtered control-record case. ## Testing - TDD RED: the new filtered-record case failed on the baseline branch because restoration fell back to the beginning. - TDD GREEN: `./gradlew :streams:test --tests org.apache.kafka.streams.processor.internals.StoreChangelogReaderTest.shouldSeekByTimestampForWindowedStoreWithoutCheckpoint --no-build-cache --console=plain` - The targeted Gradle run completed the affected streams checkstyle and SpotBugs tasks successfully. - `git diff --check` Jira: https://issues.apache.org/jira/browse/KAFKA-20876 -- This is an automated message from the Apache Git Service.
