The fallible written-bytes result of a migration: Right(bytes) encoded under the writeCodec (version-B) schema, or a Left failure (source didn't decode as the read version A, or the migrated B didn't encode). A single AvroFailure — the bridge has one failure point per direction, so no Chain accumulation.
