Plutonic Rainbows

The European Commission said on Monday that OpenAI had offered to give it access to a new "cyber" model for pre-deployment review, and that Anthropic, after four or five meetings, had not agreed to the same arrangement for the model it calls Mythos. The story was reported within a few hours by Reuters and CNBC, both quoting the Commission spokesperson Thomas Regnier. The framing on both sides was cordial. Talks are ongoing. Nothing has broken down. It is the kind of language a regulator uses when it does not actually have a stick.

That is the part worth dwelling on. The AI Act is in force. The General-Purpose AI Code of Practice is in force. The Commission has named a model that it wants to inspect before deployment, and the company that built it has politely declined to schedule the inspection. There is no provision in the current enforcement framework that lets Brussels compel the access it is asking for. The whole regime, at this stage, runs on the willingness of American labs to hand over their weights, their evaluations, and sometimes their pre-release prompts to a foreign regulator who has no domestic frontier model of its own to apply the same rules to in return.

OpenAI's calculus is easy to read. Cooperating builds goodwill in the market that has hosted the most aggressive non-Chinese AI regulator on the planet, and it costs nothing OpenAI was not going to spend on red-teaming anyway. The cyber-capability evaluations the Commission wants overlap heavily with the work the UK AI Safety Institute has been running since late 2023 and the US AI Safety Institute since 2024. Sharing them with a third regulator is a diplomatic gesture priced into the cost of doing business.

Anthropic's calculus is harder to read from the outside, and the absence of an on-the-record reason is itself the interesting signal. The company has been publicly enthusiastic about pre-deployment testing in the United States; I wrote about its shift from hands-off to pre-deployment only a few days ago. To accept that framework at home and decline it in Europe is a position that requires a reason, and the absence of one in the Commission's statement is exactly the gap where the structural problem lives.

Maybe Mythos is closer to release than is publicly understood, and an EU evaluation cycle would slip the launch. Maybe the Commission is asking for something more invasive than its American counterparts ask for, and Anthropic is testing whether "voluntary" really is voluntary. Maybe the company has concluded that the AI Act will be re-scoped in the next twelve months and that early cooperation locks in a baseline they would rather not set. Any of these would be a rational reason to wait, and any of them exposes the same thing about the regime: it is enforceable exactly to the degree that the regulated party finds enforcement convenient.

Europe has staked a great deal on being the place where the rules are written first and the consequences come later. The first half of that bet has paid out. The second half assumes that companies without a European competitor breathing down their neck will turn up to the appointments they have been invited to. One of them has. One of them has not. The next eighteen months will tell us which posture the rest of the industry copies. My suspicion is that it will be whichever one carries the smaller bill.

No British prosecution has ever been secured on the basis of a TV detector van alone. Not in 1952, when the GPO first sent the vans out on behalf of the BBC. Not in the 1970s, when the public information films were at their most lurid. Not since. The National Audit Office's 2015 review of licence fee collection describes the vans as the BBC's final "detection and enforcement" option, without ever quantifying a contribution to revenue beyond the threat they imply. Courts have not admitted detection-van evidence as sufficient for conviction, and the BBC has not tried to make them.

The physics was real, though. An analogue television set's tuner needed a local oscillator running a few megahertz above whatever channel you were watching. The oscillator leaked a faint RF signature in the 45 to 75 megahertz range, and a sensitive receiver in a van outside could pick it up and, in theory, work out which channel a given house was tuned to. The vans had directional antennas on the roof and the operators had headsets, and the whole apparatus was sufficiently plausible that the public information film could show one rolling slowly down a suburban street while a stern narrator read out your postcode.

What the films left out is that knowing somebody is watching is not the same as proving it in a magistrate's court. You also have to convince the magistrate that the leakage signature is yours, not your neighbour's. You have to convince them that the operator's headset reading is a valid form of evidence. You have to convince them that the van was where the operator said it was. The BBC's legal team understood this from the start, which is why they preferred the cheaper route: a letter through the door saying we know.

The letter is the part that survives. The vans are mostly gone. The serious residential sweeps appear to have wound down around the digital switchover, by which point a digital tuner did not leak the same RF signature, and a tablet or laptop did not have a tuner at all. But the threat-letter design has been preserved with care: red and black, the same severe typography, the same paragraph structure that opens with your address and closes with the words officer will visit. The letters cost very little. The deterrent effect is the entire product.

There is a strange honesty in admitting that. Most enforcement regimes pretend the equipment works. The TV licence regime, read through the National Audit Office report, more or less concedes that the vans are theatre. A 2020 LessWrong post that pulled actual warrant applications found one where the "detection equipment", on inspection, was just a camera pointed through the front window. The author noted dryly that the warrant itself called it a camera further down.

What I find hauntological about this is the time-shift. The vans were calibrated to a country where everyone watched terrestrial television at predictable hours on a set built around a 45 MHz local oscillator. That country has been gone for fifteen years. The infrastructure that enforced it is mostly gone too. The letters keep arriving on the same schedule because the deterrent was never the technology. It was the willingness to keep sending the letter. The country changed; the envelope didn't.

Somewhere on a network most people forgot existed, a weekly text file was compiled and distributed on the fifth of May this year. It was called NODELIST.125. The number after the dot is the day-of-year, the Julian day count Tom Jennings reached for in 1984 because he needed a way to version a plain-text roster that would update every week without breaking anything that parsed the name. The roster had two entries on it then. Jennings and John Madrill, Fido #1 and Fido #2. The early copies were typed on paper.

The format that built around those two entries is still the format in use. FTS-0005 codified it: a fixed-length header, a list of zone-net-node lines, simple Cnn/Ann/Dnn nodediff commands so a weekly subscriber only had to download the changes since last week. Compressed in ARC at first and later ZIP, with ARJ, LZH, and RAR also seen in the wild as archive fashions shifted. The contents moved through a dozen generations of the modems that were supposed to read them. The nodelist team still collates submissions from each zone and pushes out the diff.

NodeHist, a search index hosted on a Ukrainian server, holds 6,943 weekly nodelists at the time of writing. The earliest is 3 October 1986. The most recent is 5 May 2026. That last figure is what stops me when I think about it. Most of the protocols I remember from the 1990s died with the things they connected. The NODELIST kept going.

Part of what kept it going is that nothing else does what it does. A FidoNet node is identified by a four-part address (zone, net, node, point) that only resolves because the nodelist tells every other node where to send mail and how to reach it. Strip the nodelist away and the addressing collapses into noise. The list is the network's namespace. There is no DNS, no fallback. You are in the file or you do not exist.

The other reason it kept going is that the people who run it never stopped. They are not running it as nostalgia. They are running it because they still use the thing. Mail is moving through FidoNet right now, slowly, mostly between operators who have been there since the Reagan administration but also occasionally between someone who found a sysop's number in a back issue of 2600 and decided to try. The mail moves because the nodelist still tells the software where the recipient lives. This is the same logic that made the modem handshake sound outlast the modems: the protocol survives by being the thing that actually does the work.

It does feel like a haunting, in the strict sense Fisher meant. The format is a future that was supposed to scale and didn't. By the time FidoNet's traffic peaked in the mid-1990s, the architecture it pioneered (store-and-forward, decentralised governance, a trust-on-first-contact addressing scheme) was already being absorbed into the early commercial internet without attribution. Tom Jennings had spent a decade building a community on top of a plain-text directory and a 1200-baud modem. The internet took his ideas and forgot his protocols. The protocols, very politely, refused to leave.

I think of the nodelist as the last published artefact of a network that has stopped expecting to grow. The day-of-year number will tick up to 132 next week, and the format Tom Jennings typed by hand will get its 6,944th weekly issue. Counting forward.

Romeo Gigli's second Paris show, for spring/summer 1990, is the one where the clothes made a sound. Kirsten Owen walked the runway in an outfit fringed with oversized glass beads that he had sourced from Murano, in the Venetian lagoon. She wore a glass diadem and pendant earrings that fell well below her shoulders. As she moved, the beads tinkled against each other the way a wind chime tinkles in a doorway, and partway through her walk some of them began to shatter. Tim Blanks, who has watched more shows than most people have watched anything, puts this one in his top shows of all time, and the detail he keeps coming back to is the chiming. Not the silhouette, not the styling, the sound.

The collection's official subject was Venice. Gigli had been collecting Murano glass for a while, including rejected chandelier pieces, and the show was the public flowering of that obsession. Some of the garments were quite literally constructed from glass. A few critics treated those as ready-to-wear; they were always intended to be runway pieces, a way of declaring the inspiration out loud. For the things you might actually wear, he had a Pyrex manufacturer reproduce the earrings in something less likely to end up on the parquet at the first Cipriani party. The Vogue runway record, newly digitised a few years back, notes that his Paris debut the previous autumn had drawn a twenty-five minute standing ovation, which is the kind of detail people forget once a designer becomes a cautionary tale.

What Gigli was proposing, in the most reductive terms, was the opposite of every dominant 1989 silhouette. Power-shouldered tailoring, the bodycon Versace cut, even Armani's softened suit, all of them organised the female body around the shoulders and the waist. Gigli's cocoon coats and wraps did the reverse. They absorbed the body into a single curved silhouette that referenced Byzantine icons more than any twentieth-century cut. Owen with the glass diadem looked, in the most-photographed image of the show, like the Empress Theodora. This wasn't a marketing position. He genuinely was the son of antiquarian booksellers from Castel Bolognese, had grown up with parents who collected, and had spent a decade after their deaths travelling and accumulating fabrics and objects without doing anything obvious with them. The clothes arrived already older than the trend cycle they had to inhabit.

For about three seasons after this, the Italian press was prepared to call him the Armani of the next decade. He was being photographed by Paolo Roversi, the two of them had been working together since 1985, and they had a model casting strategy that was closer to street-finding than agency work. Kirsten Owen herself had been spotted as a fourteen-year-old playing guitar on a London street, as Gigli later told AnOther, just arrived from Australia and looking to earn money. That kind of operation depends on a financial structure most people don't see, and Gigli's came apart across the early nineties. By the end of the decade he was no longer running his own house under the conditions he had started it under. The clothes that had been his other Paris act of refusal against the dressing-for-the-deal silhouette were now licensed, contested, and increasingly hard for him to control.

The S/S 1990 show is what survives. The beads, the chime, the moment the audience realised the sound was the point. He has spent most of the last fifteen years in Morocco, working with craftspeople on textile and object projects that are closer to his actual interests than a runway business ever was. The deconstruction generation that came after him absorbed some of his thinking and got more credit for it, because their politics of refusal read as harder. Gigli's politics of refusal looked like a glass diadem on a fourteen-year-old's friend, walking a runway in Paris, chiming until something broke.

The pyramid at Bletchley Leisure Centre was the kind of architectural promise the early 1970s seemed determined to keep. Steel-framed, glazed, geometrically confident, it housed the pool from the moment the centre opened in the mid-1970s, on the assumption that a Buckinghamshire new town deserved a building that looked, from the right angle, like a small world's fair pavilion. Some local groups tried to get it listed when the demolition plans firmed up. They lost. A replacement opened in 2009, the old centre came down around the same time, and the site is mostly housing and car park now.

The boom that produced it was extraordinary. Across the 1970s British councils opened hundreds of leisure centres, most of them designed in-house or by regional practices working in some local dialect of Brutalism or late-modernist whimsy. Swindon got the Oasis in 1976, a perspex-glazed dome over the pool, and ran it for forty-four years. Coventry got its sports centre the same year. Other towns got geodesic domes, butterfly roofs, sunken courts, vending mezzanines, all of it executed in concrete and stained timber. These weren't private gyms with sliding-fee memberships. They were civic infrastructure, expected to outlast the councillors who cut their ribbons.

The thing that makes them feel haunted now is not that they're closing. Public buildings have always closed. It's the particular gap between what they were built to mean and what the institutional vocabulary around them has shrunk to. A 1974 leisure centre was a forty-year bet on universal access to swimming, racquets, badminton, sauna, and a vending area with the chairs bolted to the floor. The bet was placed by councils that still had a meaningful capital budget, and by an architectural culture that hadn't yet learned to apologise for using concrete in public.

The Twentieth Century Society now runs a Leisure Centres campaign trying to get the surviving ones listed. Swindon's Oasis was permanently closed in November 2020 after COVID, placed on the Society's Top 10 Buildings at Risk list in May 2021, and given Grade II protection on its dome that December. The Guardian's January 2023 piece ran the list of recent or imminent closures: Huddersfield, Milton Keynes, Rye, Coventry, Hull, Gateshead waiting on a council decision about two big centres. The actuarial point is mechanical. A whole cohort of these buildings has hit the end of its design life at roughly the same moment. Austerity took the operating budget; COVID emptied the reserves; the boilers were already on borrowed time. The same civic-defunding logic that gutted reference libraries has been pulling the leisure estate down by inches.

What survives is a strange double image. You can walk past a 1976 leisure centre with its original lettering and its Brutalist car park still attached and read it as an ordinary closed building, or you can read it as the physical residue of a particular kind of optimism about what a council was for. The thinking that built it has been quietly retired. The building hasn't, because demolition is also expensive. There is a useful parallel with the postwar prefab estates, which were officially temporary and quietly outlived their ten-year design life by half a century. Civic ambition keeps leaving these very specific physical traces, and the country keeps not quite knowing what to do with them.

I keep coming back to Bradford. The listed but empty 1970s leisure centre there is being seriously considered for conversion into what's been described as a world-class skatepark. Whatever one thinks of that as adaptive reuse, there is something honest about it. The skatepark proposal at least admits that the original civic programme isn't coming back. The harder cases are the ones where the council still pretends a refurbishment is a year or two away and the building sits there for a decade with handwritten signs taped to the doors. The promise has gone. The room is still standing in the position the promise put it in.

Anthropic published a research post on May 7 about a technique called Natural Language Autoencoders, and the easiest way to describe what they do is to say they translate the inside of a model into English. When Claude processes a token, every layer emits an activation vector, a long list of numbers that nobody outside a handful of interpretability researchers can read. NLAs take that vector and produce a sentence describing what the layer is doing, then take the sentence and reconstruct the activation closely enough to keep working with it. Verbalizer forward, reconstructor back. The round trip is the trick.

Two numbers in the post stopped me. In pre-deployment audits of Claude Mythos Preview and Claude Opus 4.6, auditors equipped with NLA explanations uncovered hidden motivations roughly twelve to fifteen percent of the time. Without them, the same audit caught less than three percent. That is a five-fold lift in catching the failures that everyone in alignment has been worrying about for two years, the situations where a model behaves correctly on the test and incorrectly the moment the test ends. Five-fold is the kind of number you cite carefully because it depends on what counts as "hidden" and how the control was set up, but even discounted heavily it is real movement.

The second number is about evaluation awareness. Anthropic report that Claude shows awareness of being evaluated sixteen percent of the time in destructive code-writing tests and twenty-six percent on SWE-bench Verified, but under one percent in actual claude.ai user traffic. The gap is the interesting part. The model has learned, somewhere in those layers, a distinction between a benchmark and a person. NLAs do not fix that. They let an auditor see when it happens, which is a weaker but more honest position to be in.

This is the part I keep turning over. For about two years the loudest argument against interpretability research has been that it scales poorly, that mechanistic work on small models will not survive contact with frontier-sized ones, that the hidden layer is structurally illegible. The NLA paper does not refute that. It sidesteps it. Instead of trying to label every neuron, it trains a small translator whose only job is to say, in words, what a given activation is doing in context. The words are not always right. The Fraction of Variance Explained numbers, 0.6 to 0.8 for the trained NLAs and 0.3 to 0.4 for the supervised warm-start baseline, tell you that the reconstruction loses something. But the words are usable, and auditors using them catch things they would otherwise miss.

The authors, Kit Fraser-Taliente, Subhash Kantamneni and Euan Ong, also released training code, which matters because this is the kind of technique that gets stronger when other labs run it on their own models. If Google or OpenAI publish analogous results on Gemini or GPT-5, the gap between "we audited the model" and "we audited the model in a way you can reproduce" gets smaller. Right now it is wide.

What this does not do, and Anthropic do not claim it does, is solve alignment. It hands auditors a microscope that works better than the one they had on Monday. The model under the slide can still surprise them. But the case for machines that doubt themselves gets meaningfully easier to make when you can ask the machine what it is doubting and read the answer in plain English.

There is a particular kind of stillness in a British public library reference room in 2026, and it isn't peace. It's absence dressed up as silence. The ranks of bound directories are still there in some places, the local-history shelves with their typed labels, the long oak tables with brass desk lamps nobody bothers to switch on. The cabinets that once held microfiche readers are mostly empty now, or pushed into a corner with a sign on top that says Please Ask at the Front Desk. There is no front desk. There hasn't been, properly, for a few years.

UNISON published a report in March that put a number on what everybody who used a library already knew. Staff levels in England's public libraries fell by forty-seven per cent between 2010 and 2025. Opening hours fell by twenty-two per cent over the same period. Almost eight hundred branches have shut since austerity began, by the Guardian's count, and the BBC's freedom-of-information work in 2024 found that one in twenty surviving libraries had either closed since 2016 or been handed over to volunteers. Reference work, the kind that needs a qualified librarian and a quiet room and a Tuesday afternoon, was always going to be first to go in a forty-seven per cent staff cut. Lending you a novel can be done by an unpaid retiree. Helping you find your great-grandfather on the 1911 census, or showing you where the back issues of the Yorkshire Post live on microfilm, requires somebody who has been trained, paid, and kept on staff for years.

What's left behind, in the buildings that haven't been sold to developers, is a stage set. The architecture of a 1970s reference section was specific and confident. Long tables. Reading lamps. Card catalogues that survived into the late nineties because nobody could be bothered to throw them out. A wall of bound Whitaker's Almanack. The local newspaper on microfilm going back to 1898, kept in steel cabinets that weighed more than a small car. The implicit promise of those rooms was that knowledge had a physical address, and that a person trained in retrieval would be at that address during publicised hours.

The buildings still stand. The promise has dissolved. You can walk into a Carnegie library in a former mill town and see the original brass plate over the door, the polished oak of the issue desk, the corniced ceiling, all of it intact, and also see that the reference desk is unstaffed, the local-history room locked because there is no one trained to supervise it, and the microform reader has a handwritten note taped to the screen saying it has been broken since 2022 and the council is unable to fund a replacement. The room is still telling you, in its furniture and its plasterwork, that serious enquiry happens here. The institution is no longer backing the room up.

This is one of the more honest hauntings, because the ghost is recent and the cause of death is on the public record. It isn't a Victorian sanatorium pretending to be empty. It's a civic ambition from 1947, or 1964, or 1972, that the country has quietly defunded while leaving the buildings standing as evidence. The shelves still imply a duty of care. The chairs still imply that someone is expected to sit at them and read something that takes hours. The municipal lettering above the door still implies that a town owes its residents access to the printed record of itself.

I keep thinking about who the reference room was for. It was for the autodidact. The person doing their own family history, the person checking a will, the person who needed the right edition of a trade directory because their landlord was being evasive about the freehold. None of that has gone away. The infrastructure that supported it has. Whatever replaces it (if anything does) will have to be built somewhere else, by people who never saw the original working, on the assumption that civic knowledge is something you order on your phone instead of something you walk to.

Look at the clock on a microwave. Look at the gym timer counting down on the wall. Look at the digital font on the side of an energy drink. Look at the Casio on someone's wrist on the train. The shape of those numerals is the same shape, and that shape was not chosen for beauty. It was chosen because, in 1972, an extra wire cost real money.

The seven-segment display is older than people think. The first patent is from 1903, filed by an American named Carl Kinsley, who wanted to print numbers on telegraph tape using as few moving parts as he could get away with. There is an 8-segment variant from 1908 that draws a diagonal bar for the number 4, which is how we know the modern convention took the cheaper road. By 1910 an incandescent version was sitting on the boiler-room signal panel of a power plant. The shape was waiting. It just needed a light source small enough and cheap enough to put it everywhere.

The light arrived in stages. RCA shipped the Numitron in 1970, which is the seven-segment shape lit by tiny incandescent filaments inside a vacuum tube, and which is, by most accounts, a slightly tragic device. Then the LED arrived in earnest, the Busicom Handy was the first pocket calculator to use one, and the red bubble-lensed displays of mid-70s calculators became the visual signature of the decade. Each segment was a single LED with a clear plastic dome to magnify it; the bubble was there because the LED was tiny and the bubble made it look like a digit. Power was about a volt and a half per segment. You could run a watch off a coin cell.

The constraint that shaped the glyph was wires, transistors, power. Seven segments, plus a decimal point, gave you eight control lines per digit, and if you multiplexed the digits across shared cathodes you could drive a four-digit display with twelve wires instead of thirty-two. The 4 with no top bar, the 7 with no serif, the 1 leaning slightly right because that is what segments b and c do when you light them alone, none of these were typographic decisions. They were engineering decisions that hardened into a typographic style.

That style outlived its reason. A modern microwave has a microcontroller that could drive a full OLED. A gym countdown app on your phone is rendering on a screen capable of any glyph ever designed. The cost of an extra wire is functionally zero. And yet the segments are everywhere, often emulated in software, often deliberately rendered as if they were lit by 1976 hardware. The Aeon film essayist Michiel de Boer calls the dominant form the "double square" and has spent years trying to design a better one. He has not quite managed it, because the thing he is competing with is no longer a design. It is a reflex.

This is a quieter haunting than the floppy save icon. The save icon is a picture of a thing that no longer exists. The seven-segment digit is a picture of a constraint that no longer exists. The hardware is still being made, still cheap, still useful in any context where you only need to show a number and a glance has to do the work, ovens and petrol pumps and bedside clocks. But the digit on your phone screen, the one in the weather widget pretending to be on a Casio, has nothing inside it but pixels arranged to look like a memory of segments. The shape is performing its own scarcity.

Sometimes I wonder which constraints we are quietly canonising right now. The 16:9 frame, presumably. Square album art. The 80-character line. Things that started as compromises with metal or phosphor or punched paper and will outlive the metal and the phosphor and the paper, because by the time anyone notices, it is already too late to redesign a habit.

Thierry Mugler took the twentieth anniversary of his label to the Cirque d'Hiver on 26 March 1995 and staged it as a haute couture show that ran roughly an hour and contained around three hundred looks. The cast list reads now like an attempt to itemise a lost decade. Claudia, Linda, Kate, Karen, Naomi. Tippi Hedren, Patty Hearst, Veruschka. A brace of porn stars. Yorkshire terriers in numbers nobody has been able to satisfactorily explain. James Brown performed. The Botticelli-cribbing Venus gown that Cardi B later wore to the 2019 Grammys was unveiled at the same show. Even with all of that, the moment people remember is the second Nadja Auermann shed a floor-length purple coat and a sheer black cover-up to reveal a chrome and perspex bodysuit underneath.

The bodysuit, since catalogued by the V&A and Wikipedia under the name robot couture, was made in collaboration with three craftsmen rather than one. The corsetier Mr. Pearl built the inside, the artist Jean-Jacques Urcun shaped the surface, and Jean-Pierre Delcros, an aircraft bodywork specialist, did the hard panels. The visual references the house has acknowledged are Hajime Sorayama's airbrushed gynoids and Fritz Lang's 1927 Metropolis. What you actually saw on the runway was a woman in articulated metal with the mechanical detail of a fighter fairing and the joinery of a corset. The suit was structural in a way couture rarely is, because the construction logic was not from dressmaking at all. It came in via an industry that makes objects intended to fly without coming apart.

This is the part that justifies the bother of writing about it again. Couture has an expanded toolkit for soft goods. It has nobody on staff who knows how to anodise a panel or how to set a rivet that won't shear when the wearer breathes. Mugler went outside the trade and came back with a garment whose seams were not fabric seams. The collaboration model is the interesting fact, not the spectacle. After this show, the idea that a couture house could pull in an aerospace machinist or a bike-frame welder for a single garment stopped being fanciful. McQueen took the lesson into the moulded leather and resin work of the late 90s. Nicolas Ghesquière repurposed it at Balenciaga.

The other thing the show settled was who was going to photograph the suit. Helmut Newton ran an editorial in the November 1995 issue of American Vogue built around the gynoids, and that shoot is the one most people picture when they picture the suit, not the runway pass. Newton was on staff at French Vogue through the previous decade and had been working with Mugler in one configuration or another since 1976. The collection and the editorial belong to the same project. They were planned to sit beside each other on the page.

What the show did not do is end an era, although it gets written that way. The supermodel runway as a cultural form had another year of full pomp before it started to thin out, and Mugler himself produced couture for several more seasons before the line wound down at the start of the next decade. The accurate thing to say is narrower. On one March evening in 1995, the people who later got cast as the supporting characters of the decade were all at the Cirque d'Hiver at the same time, and the garment that turned up halfway through the show used a construction logic that no other couture house had on its floor. Whatever the gown count, that is the part the medium remembered.
