A Kafka Streams implementation of Allen's Temporal Logic - a toy demo

I had an idea for a Kafka Streams implementation of Allen’s Temporal Logic (from the early 80’s), and came up with this. It’s just a toy/demo but I thought it was pretty cool what the AI (with significant help from me) could come up with in a few hours of effort.

Re: [VOTE] 4.3.0 RC1

Hi Mickael, I did the following: - verified the checksums and signatures - build from source (java 21) -> run quickstart, basic produce/consume with Classic and Consumer groups - run basic consume/produce on both docker images - run the network degrade sys test that was failing on your side. I got a green run for the test_rate on 4.3 after some retries https://confluent-open-source-kafka-branch-builder-system-test-results.s3-us-west-2.amazonaws.com/trunk/2026-05-11--001.f3134388-b3df-48e5-ae8b-98d07ddfff55--1778526564--apache--4.3--84b51283d6/report.html +1 (binding) Best!

@Maciej: You mean within Strimzi? The system tests we have covering OAuth passed. But I have not done any special testing for that as OAuth is not really my specialty.
