Explanation

The stated intent is to upgrade github.com/IBM/sarama for retry ordering. The reviewed go.mod also upgrades github.com/klauspost/compress, github.com/pierrec/lz4/v4, and github.com/pingcap/errors. The available evidence does not connect these additional upgrades to the Sarama fix or another pull request objective.

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win

Resolve both merge conflicts before merging.

go.mod still contains <<<<<<<, =======, and >>>>>>> markers in both dependency blocks. Go cannot parse the module file, so go mod tidy and builds fail. Resolve each block to one valid set of dependency requirements, then rerun the checks. The CI logs report these parse failures.

Also applies to: 51-65
