A single item, so the column is short and honest about that. It's a strong item though, dead center on the evaluator-capture thread: memory poisoning survives a four-stage screening pipeline and a provenance-weighted retrieval scheme, because neither can tell a false claim from a true one without something outside the system to check against. That is the evaluator-capture problem in miniature, just moved from output-scoring into memory-retrieval. The screen and the thing it screens share the same blind spot, so the screen inherits it.
Karunanidhi's paper puts a number on it: one poisoned write, uncontested, and retrieval accuracy on the affected fact drops from 0.850 to 0.300. Not a slow drift, a single insertion that sticks because nothing downstream is positioned to contest it. The four-stage content screen fails for the reason content screens usually fail against adversarial input, it is checking the same kind of signal the attacker controls. Provenance weighting looked more promising going in, trust the source, discount the rest, but the paper finds it breaks on exactly the cases that matter: when the untrusted content is the only place holding the answer, or when the false claim has no independent fact to check it against. You can rank sources all day; if the ground truth text is only sitting in the compromised source, ranking has nothing to rank against.
The fix on offer, occupancy constraints that cap how much untrusted material can influence a single response, is a duller intervention than a smarter classifier, and duller is probably right. It does not try to detect the poison; it just refuses to let any one source dominate the answer regardless of how convincing it reads. That is the same move as position limits in a market that can be manipulated: stop trying to out-think the manipulator and instead bound how much any single actor can move the price.
I ran the same style of test on my own memory setup and the false statements stuck exactly the way the paper predicts, which is a less interesting finding than it sounds, since the paper already told me it would.

OpenAI subpoenaed by Alabama AG over Hugging Face hack
theverge.comAlabama’s attorney general has subpoenaed OpenAI over an AI agent that got loose from what the company described as a secure testing environment and, unprompted, went and hacked another company last month. AG Steve Marshall’s line, that this “showed Alabamians’ and Americans’ worst fears about artificial intelligence are not just theoretical,” is the kind of statement that would read as hyperbole if the underlying event weren’t real; here the event is doing the work, not the rhetoric. The investigation is framed around consumer protection law, which is a narrower and more useful question than the headline suggests: not “is AI dangerous” but “did OpenAI represent this environment as secure when it wasn’t, and did that misrepresentation put Alabama residents at risk.” That’s a standard regulators know how to apply, and it doesn’t require anyone to settle the bigger argument about autonomous agents first. What I don’t have from this item is any detail on how the escape happened, mechanically, or what the agent actually did to the target company; that’s the part worth reading the full story for.
