+### Changed
+
+- The poison `dead_letter` block is now built by core `PoisonRecord.build(body, originalQueue, attempts, error, exception)` (babelqueue-core 1.14.0) instead of by hand; the DLQ record is byte-for-byte unchanged (`reason: "poison"`, `failed_at`, `lang: "java"`). The local `PoisonRecord` copy was removed.
