The Morning Brief. Saturday, October thirty-first, twenty twenty-six. Halloween edition.

Good morning, Rob. It’s a beautiful Halloween morning, and today’s brief has a little bit of everything: a possible new standard for how websites signal their AI training preferences, a serious software supply-chain incident, a dramatic Martinsville finish, and a few good local and weekend picks. Let’s get into it.

First, OpenAI, Google, Microsoft, and Anthropic have backed a proposed common way for website owners to express preferences about AI training. The idea is to use a shared signal in robots dot text, so publishers would not have to configure separate rules for every AI provider.

The proposal was submitted to the Internet Engineering Task Force. It is still an Internet Draft, and use would be voluntary. That means it could make the technical side simpler for website owners, but it is not a finalized standard and it cannot guarantee every crawler will follow the signal. The proposal and OpenAI’s announcement are linked in the show notes.

Second, a compromised Claude Code extension appeared in Cursor’s extension marketplace for about eleven hours on October twenty-ninth. Security reporting says the malicious version tried to create persistent access through an SSH backdoor and send system information to an attacker-controlled server. As many as five thousand developers may have been exposed.

Cursor removed the extension, temporarily disabled its marketplace, and investigated. Researchers also found implementation errors that may have blocked remote access on many affected machines. That is encouraging, but it does not rule out compromise. The affected version was two point one point three one three, available from about two twenty-seven in the morning until one thirty-five in the afternoon Pacific on October twenty-ninth. Anyone who installed it in that window should review Cursor’s remediation guidance. This is a useful reminder that extensions are software supply-chain dependencies, and deserve the same care as other tools installed on a development machine.

In NASCAR, Chandler Smith won Friday night’s Truck Series race at Martinsville after taking the lead on a restart with thirteen laps to go. Layne Riggs had led one hundred fifty-six laps and won both stages, but lost momentum coming out of Turn Four. Smith earned his third win of the season. Riggs finished third and narrowed his championship deficit to Kaden Honeycutt to just twenty points, with next week’s finale at Homestead-Miami ahead.

There’s more racing this weekend. The O’Reilly Auto Parts Series is at Martinsville today at one p.m. Pacific on The CW. Sunday’s Cup Series Xfinity five hundred starts at eleven a.m. Pacific on NBC. Martinsville’s tight corners should make passing difficult, with the championship picture at stake.

Closer to home, Franceschi Park has opened more than fifteen hundred feet of new trails across its seventeen-acre Riviera property. The paths connect areas that were harder to reach, alongside restored native habitat, new benches, and access to historic botanical features. One trail leads to a sandstone bust of botanist Francesco Franceschi. The trail project cost about seventy-seven thousand dollars. It sounds like a peaceful Halloween weekend walk, with less reason to stick to Franceschi Road.

In Goleta, the Planning Commission postponed a decision on the proposed Greenbark battery-storage facility. The plan calls for thirty-six Tesla Megapack units, with up to one hundred twenty megawatt-hours of storage. Commissioners want to see a broader citywide study of appropriate locations for utility-scale batteries, expected in April of twenty twenty-seven. It’s the familiar local challenge of expanding clean-energy infrastructure while working through land-use and safety concerns.

For the hobby corner, Games Workshop has a new eight-minute Warhammer Academy painting tutorial featuring the Oath Fulfilled commemorative miniature and its Tone Pro paint range. If you’re curious whether the new paints behave differently from familiar supplies, an actual painting demonstration is more useful than promotional images alone. The video is linked below.

And there’s a fun behind-the-scenes Star Wars story from LightBox Expo. Lucasfilm’s animation development team discussed how projects as different as LEGO Star Wars and Maul: Shadow Lord take shape. They talked about starting with character, adapting the visual style to the audience and tone, and finding creative talent with both passion and technical ability. One universe can hold very different storytelling styles when the project knows what it wants to be.

Finally, the Los Angeles Kings host the Buffalo Sabres today at one p.m. Pacific. After Thursday’s six-to-five overtime win over Ottawa, the Kings say they’ve been practicing a more structured three-on-three approach: keeping possession, choosing positions carefully, and simulating overtime situations. They have two overtime wins and two losses so far, and rank third in the league in offensive-zone possession time during three-on-three play, according to the team’s analysis. Buffalo comes in after a wild seven-to-six win over Anaheim. Could be a lively afternoon game.

Before we go, the three things I’d keep an eye on: whether the AI training-preference draft moves through the standards process; whether Cursor’s investigation or developer follow-up uncovers any confirmed compromises; and how the Kings’ overtime strategy holds up against Buffalo.
