It's not even clear if AI was used to find the bug: they mention modeling the software with an "ai native" language, whatever that means. What is not clear is how they found themselves modeling the gyros software of the apollo code to begin with.

But, I do think their explanation of the lock acquisition and the failure scenario is quite clear and compelling.

They have some spec language and here,

https://github.com/juxt/Apollo-11/tree/master/specs

have many thousands of lines of code in it.

Anyways, it seems it would take a dedicated professional serious work to understand if this bug is real. And considering this looks like an Ad for their business, I would be skeptical.

Could the "AI native language" they used be Apache Drools? The "when" syntax reminded me of it...

https://kie.apache.org/docs/10.0.x/drools/drools/language-re...

(Apache Drools is an open source rule language and interpreter to declaratively formulate and execute rule-based specifications; it easily integrates with Java code.)

How did you pick out AI native and miss the rest of the SAME sentence?

It's not even clear you read the article

The intro says “We used Claude and Allium”. Allium looks like a tool they’ve built for Claude.

So the article is about how they used their AI tooling and workflow to find the bug.
