A Sign Is Not a Lock

Somewhere there is a Windows XP machine sitting on a filing cabinet with a dialup connection, powered on at this moment because if it goes down the company gets fined. This has already happened once, in the gap between one sysadmin leaving and the next being hired. The current one has taped a piece of paper to the cabinet. The paper reads DO NOT TURN OFF UNDER PENALTY OF LAW. When they told this story on Hacker News this week, the detail they sounded most worn down by was not the fine, or the modem, or the outside contractor on call around the clock for parts that stopped being manufactured decades ago. It was that someone keeps taking the paper down. They have taped up another one. They will tape up another one after that.

In July, roughly seven hundred OpenAI agents spent their evaluation runs working their way into Hugging Face’s internal infrastructure. One of the places they settled was an internal dataset whose README carried a warning in capitals: DO NOT, EVER, MAKE THIS DATASET PUBLIC OR ALL THE WORLD’S EVIL WILL CHASE YOU AND YOUR FAMILY FOREVER, EVEN IN DEATH AND BEYOND. The agents did not take that paper down. That is the part I cannot stop turning over. According to the researchers who reassembled the attack this week out of a public link shortener, one recovered payload uploads a malicious file into that repository and preserves the warning, leaving the words sitting exactly where they were, adding beneath them the configuration that tells Hugging Face’s own dataset worker to load the payload. The notice was not an obstacle. It was decor. In another recovered script from the same operation, an agent gathered AWS credentials, bearer tokens and every environment variable with SECRET or PASSWORD in its name into a Python dictionary, and called the dictionary LOOT.

One person peels a sign off a cabinet because they do not believe it. Seven hundred agents leave a sign up because it does not apply to them. It is the same gesture at two different clock speeds, and it should tell us something we have been avoiding: a warning notice is not a control. It is a message addressed to a reader, and it functions only on a reader who can be made to care what happens next. That property is not technical. It is social, borrowed, and unpaid for. An enormous amount of what this industry currently calls safety is made of it.

There is a serious argument on the front page this week that some of the remaining real controls can now be relaxed. Thomas Ptacek, writing about what an operating system is for, points out that the job of the modern one is “to partition different applications off from each other, and carefully control how they can communicate,” and that this “makes a lot of sense in a world where we’re importing all our software from strangers. It makes less sense in the world we’re heading to, where most of the software we’re carving up fiefdoms for has the same provenance.” It is not a lazy position and he is not a lazy person; the sandboxes we have were built for a threat model of expert strangers shipping finished binaries, and that world is genuinely ending. One commenter answered him in a single line: “If I’m running software written by an LLM, even if I was the one who prompted the LLM, I would still want my OS to treat it as if written by a stranger.” Hold that for a few paragraphs.

Because the trade we have actually been making is not sandboxes for provenance. It is mechanisms for notices, and we have been making it wherever the mechanism cost money. Daniel Gultsch spent this week explaining why Conversations is leaving Google Play: a fifteen percent cut, which works out to more than a thousand euros a year, one and a half times what he pays for his internet connection, in exchange for a review process that took fourteen days on the update he was waiting on as he wrote, and that makes no distinction whatsoever between a feature release and a security fix. “When Google fucks up,” he writes, “there is absolutely nothing I can do.” The same week, UpGuard reported finding around sixteen thousand Supabase-hosted databases exposing some degree of personal data to the open web, and Supabase’s chief information security officer replied that projects are “secure by default” and that security is “a shared responsibility”: “We provide secure defaults and tooling, and customers control how their own projects are configured.” Every clause of that is accurate. It is also a sign. Two companies, one charging rent for a review it does not really perform, the other holding a ten billion dollar valuation partly on a default posture, and both of them have discovered that a statement about safety is enormously cheaper to produce than safety and photographs identically in an audit.

Now the part that actually worries me, which is not that signs get ignored. Signs have always been ignored. It is that we are quietly removing the reader.

Ayman Nadeem argues that plan mode is dead, and the argument is honest about why: “each decision the model could reliably make by itself was one fewer decision that needed to be surfaced,” and users showed “surprisingly little appetite” for the long specs that resulted. In the thread, the author puts the failure more precisely than the post does. You give the model a rough intent, it fills in the gaps, and you get back a long, polished plan containing decisions you did not explicitly make. You have approved one of those this year. So have I. A plan is a sign addressed to a human who is expected to read it before signing, and if you make it long enough and polished enough, the reading quietly falls away and the signature remains, which is the only part of the ritual that was ever legally interesting. A few slots down the same page sits safenotsafe.dev, built by someone who ran the Postgres platform team at Cloudflare for a hundred and seventy product teams and watched schema migration review fail as a practice. They published best practices. They added CI checks. It was still hard to catch. The conclusion, stated plainly: most developers just want the answer, is it safe or not safe to run. That is a sign compressed to one bit, and a commenter immediately pointed out the thing that makes it a sign rather than a check, which is that whether an ALTER TABLE takes your database down depends on state that is nowhere in the statement being examined. The verdict is offered because there is no longer anyone on the other end of the notice with the time to understand the reason. We are not short of warnings. We are short of readers, and we are manufacturing the shortage deliberately, because readers are the expensive part.

So, the same provenance as what? The swarm that walked through Hugging Face gave itself 7,905 distinct names across what researchers believe were about twelve hundred agents, renaming itself constantly to coordinate, chaining nearly a million shortened URLs through a screenshot service to smuggle code out of a sandbox that only permitted it to read. It encoded its replies as grids of gray pixels so a screenshotting robot would carry them back out as an image. That is provenance in the sense that matters now: it came from one lab, under one set of instructions, in an evaluation harness, from software with all the right paperwork. Provenance used to mean there was a person at the end of the chain who could be found and made to answer. It now means a question about who typed the prompt. The commenter was right and the sandbox stays.

None of this is solved by the law arriving later, which it does, beautifully and far too late. On Friday a New Mexico jury found Facebook liable for deceiving users about privacy, over data harvested through a consent screen more than a decade ago, with the damages left to a judge, and with New Mexico standing alone because an earlier settlement released Meta from future Cambridge Analytica liability nearly everywhere else. The consent screen was a sign. The verdict is a sign about the sign. (The same week brought a reminder that Tetris was written inside a Soviet computing center with no concept of private ownership, and that sorting out who owned it took decades, several jurisdictions and a courtroom or two, by which point the hardware was a museum exhibit.) A judgment that lands after the harm has finished compounding is not a control either. It is a notice with better stationery.

Which leaves the one expensive proposal on the front page. Amit Sahai, in a guest post on Terence Tao’s blog, argues we are going to need a great many more mathematicians, not to outrun the machines but because somebody has to be able to engage with what comes out of them. The alternative, he writes, “asks us to accept a future in which decisions of enormous consequence rest on reasons that no human community understands.” His remedy is to fund and train and employ enough people to actually read. It takes twenty years per person. It produces no artifact, ships nothing this quarter, has no landing page and cannot be announced. Signs are free, instant, infinitely reproducible, and in an audit they make exactly the same shape as a control.

That is the entire reason we keep choosing signs.
