I have been thinking a lot about AI and integrity. Part of that is contextual integrity. I recently found two papers on the topic.
“CIMemories: A Compositional Benchmark for Contextual Integrity of Persistent Memory in LLMs“:
Abstract: Large Language Models (LLMs) increasingly use persistent memory from past interactions to enhance personalization and task performance. However, this memory introduces critical risks when sensitive information is revealed in inappropriate contexts. We present CIMemories, a benchmark for evaluating whether LLMs appropriately control information flow from memory based on task context. CIMemories uses synthetic user profiles with over 100 attributes per user, paired with diverse task contexts in which each attribute may be essential for some tasks but inappropriate for others. Our evaluation reveals that frontier models exhibit up to 69% attribute-level violations (leaking information inappropriately), with lower violation rates often coming at the cost of task utility. Violations accumulate across both tasks and runs: as usage increases from 1 to 40 tasks, GPT-5’s violations rise from 0.1% to 9.6%, reaching 25.1% when the same prompt is executed 5 times, revealing arbitrary and unstable behavior in which models leak different attributes for identical prompts. Privacy-conscious prompting does not solve this—models overgeneralize, sharing everything or nothing rather than making nuanced, context-dependent decisions. These findings reveal fundamental limitations that require contextually aware reasoning capabilities, not just better prompting or scaling...
Today’s contests will help shape the fiercely contested midterms this fall to determine control of Congress
Hello and welcome to the US politics live blog.
Attention turns to Florida and Alaska, where primaries later on Tuesday will highlight Republican-led redistricting efforts that have scrambled congressional maps.
Donald Trump voted by mail in Florida’s Republican primary, Politico reports, citing Palm Beach County voting records. The White House has confirmed the president’s mail-in vote, according to the New York Times, which added that this is at least the third time the president has mailed his ballot.
A northern California county plans to hire Tina Peters, the prominent Colorado election denier recently released from prison, to work on elections. Shasta county, a conservative region home to 182,000 people, has emerged as a center of the US election denialism movement in recent years. California governor Gavin Newsom’s office said the state is investigating Peters’ hiring.
CNN has said it stands behind reporter Kristen Holmes after Trump repeatedly told the CNN reporter to “be quiet” and accused her of being “a fake reporter” during questioning over conditions onboard the USS Abraham Lincoln. Shortly after the president reprimanded Holmes, the White House invoked her children in a social media post further attacking the reporter when she asked about comments from Democratic senator Jon Ossoff in a speech on Sunday. He had told a crowd that Trump “doesn’t want to do the job” and instead “wants to build his ballroom and travel with Natalie on their apparently defenseless flying palace gifted by the emir of Qatar”. It was an apparent reference to Natalie Harp, the president’s executive assistant.
Trump again threatened to bomb Oman if it “gets in the way” of his effort to end the US-Israel war on Iran, as the two-month window to negotiate peace with Iran expired on Monday with no end to the conflict in sight. “If Oman gets in the way, we’ll bomb the shit out of them,” Trump told Fox News.
Trump said that North Korean leader Kim Jong-un had responded to his overtures after he ordered the US to scale back military exercises with South Korea. Speaking to reporters in the Oval Office, Trump was asked why Kim had not responded to his overtures.

Health data appears to be most affected by administration’s attempt to wipe findings that don’t align with its priorities, tracker shows
A database of federal law enforcement officer misconduct records. A survey measuring physical, sexual and emotional violence against children and youth. Real-time pollution readings collected by air quality monitors from US embassies around the world.
These are among the hundreds of federal datasets that the Trump administration has taken down or altered as part of its aggressive campaign to wipe all mentions of data findings that do not align with the administration’s priorities.

Marta Kostyuk and Peyton Stearns beat American pair 6-2, 1-6, 10-8
Serena and Venus enjoy ‘fun’ on-court reunion despite defeat
Just one game into the family reunion of the decade, Venus Williams launched herself inside the baseline in her single-minded pursuit of a puffball second serve. For a brief moment, grandstand stadium at the Cincinnati Open had been transported back 15 years. Williams pounded her forehand return directly at the right hip of her opponent Marta Kostyuk, instantly eliciting gasps from the audience as she snatched the point. Back when the Williams sisters spent their spare time racking up grand slam titles for fun, this is how they dealt with most adversaries.
In the end, Venus and Serena’s first doubles match in four years, and just their second in the past decade, ended in a rollercoaster 6-2, 1-6, 10-8 defeat to Kostyuk and Peyton Stearns, another wildcard pair and two formidable singles players. For once, the result did not seem to matter.

• The best cordless vacuum cleaners, tested
• How to make your vacuum cleaner last longer
Buying a vacuum cleaner isn’t as easy as you might think. With so many brands and models to choose from, it can be bewildering. Sticking with established brands isn’t necessarily a safe bet, with past performance being no guarantee that the latest models will be as good. Meanwhile, prices can be deceptive, with some affordable models now closing the gap on top-of-the-range brands when it comes to cleaning performance.
You can’t know all this by browsing through a department store or online. The ideal thing to do would be to take a few models home to try them out – but good luck persuading anyone to let you do that. Thankfully, you won’t have to try because I’ve tested an array of models for you. I’ve measured each one’s ability to perform a range of real-world cleaning jobs, so you can discover the best vacuum cleaner for you.

After Tony Romo’s arrest last month, TMZ published a 31-minute “extended cut” of the body-camera footage from the Wisconsin police officer who arrested CBS Sports’ star NFL analyst on suspicion of operating a vehicle while under the influence.
It’s an uncanny watch. The former Dallas Cowboys quarterback’s familiar goofy geniality collides with the gravity and stilted formality of an encounter with law enforcement. The video of a disoriented Romo struggling to answer basic questions and failing a field sobriety test, and his rictus-grinning, disheveled, head-askew mug-shot, form a glaring contrast with his smart-suited look a year earlier: beaming as he posed in the spotlight with his play-by-play partner, Jim Nantz, at the network’s preseason media preview.

If primary elections elsewhere this summer were tussles between progressives and moderates for the direction of the Democratic party’s political future, Tuesday’s contests in Florida could not be more different.
In a former swing state that has in recent years become reliably red, moderate Democratic candidates Alex Vindman and David Jolly are heavily favored to become the party’s nominees for November’s Senate and governor’s race, respectively.

The snake didn’t start the fire. So says a Virginia science teacher who owns a python that was found outside its enclosure in a middle school classroom that caught fire recently.
Authorities, meanwhile, have publicly blamed the fire on the snake, named Nanner, alleging the python knocked over a heat fixture in her owner’s classroom, igniting a blaze that caused damage at Bedford county’s Forest middle school and killed a tortoise there.

When Jonathan Hau-Yoon wanted to make something as meaningful as the environmental strategy game Terra Nil, he turned for inspiration to his longtime partner. Sabrina Becker had worn a dress she made herself to their very first date, and would have studied costume design abroad had hypermobile Ehlers-Danlos syndrome (a connective tissue disorder I also have) not put those plans on hold.
The pair developed a concept around the creative decisions involved in dressmaking, like trying to fit pattern pieces on to available fabric while observing the grain line (the direction of the thread in woven fabric). Other decisions followed: a 3D model on which to place garment pieces, buttons and trims with which to decorate them, clients with commissions as creative prompts.
