Yunseop Eom commented on KAFKA-18838:
-------------------------------------
Update on PR #22947: https://github.com/apache/kafka/pull/22947
The PR makes arbitrary memory-record fixtures deterministically invalid instead
of relying on random bytes occasionally producing a valid record set. It
preserves payload variation, matches the declared buffer length, and uses an
unsupported magic value to enforce the malformed-input contract.
Validation completed with the Raft test suite, including
ArbitraryMemoryRecordsTest#testGeneratedRecordsAreAlwaysInvalid, and git diff
--check. The PR is open and awaiting review.
