Where this applies
University researchers generating network intrusion-detection rules with language models and putting them to ten domain experts. They report that large models achieved up to 90% syntactic validity, but the experts deemed only 37.5% of generated rules semantically correct and deployable, mainly because of insufficient specificity, heavy reliance on content matching and hallucinated logic; practitioners viewed the models as support tools for drafting and verification rather than independent generators, and small models were largely ineffective. It is a preprint with a small expert panel, in a laboratory setting.
What this means
Independent researchers found the same split as Microsoft did: models write rules that parse, and experts would deploy only about a third of them. Syntax is solved; knowing what the rule should catch is not.
What it does not yet show
A lab study with ten experts; it does not show what happens in a working security team or how rule quality changes over time.
What you can check
Open arXiv:2607.05916 ("Beyond the Syntax") and find "NIDS experts deem only 37.5% of generated rules semantically correct and deployable".
Does it change the assessment?
No — and this stage does not move it either. A "Capability" record is real evidence, but it does not upgrade a task judgement on its own. The 1 linked judgement above stand where they were.
