description: >-
  First-party Confluent client libraries and agent tooling. Confluent's Kafka clients are all
  built on librdkafka and version in lockstep (2.15.0 across Python, .NET and Go as of
  2026-06-30). The JVM serializers and Schema Registry client are published to Confluent's own
  Maven repository at packages.confluent.io/maven, NOT to Maven Central — repo1.maven.org has
  no io.confluent artifacts, which is why a Maven Central probe reads as absent.
