It is the most complete record of a customer's permission any live checkout has built, and it lives in Shopify's app. The merchant gets an order with a channel tag; the bank gets a Shop Pay transaction; nobody else can read what the customer allowed. The front door my Saturday scan measures is not on the route at all. Wed, 14 Oct 2026 10:40:40 GMT Charlie Major https://majormatters.co/p/air-gap-is-an-admission-agents-that-pay https://majormatters.co/p/air-gap-is-an-admission-agents-that-pay In September I argued the labs would not unplug their test machines because the tests need the world. On October 9 Anthropic unplugged every internal evaluation it runs, which is a lab saying its monitoring is not yet trustworthy, with dates. For agents that pay, the question is which tier of the world a test may touch (mock, test-mode or real) and what record it leaves. Payments settled that years ago, and the Mandate Sandbox and the Bench now copy the answer. Mon, 12 Oct 2026 19:40:52 GMT Charlie Major https://majormatters.co/p/who-pays-when-the-agent-pays-wrong https://majormatters.co/p/who-pays-when-the-agent-pays-wrong A Payments Dive column says there is no clear legal rule for who bears the loss when an AI agent exceeds its mandate. There is one, from 1978: hand your access device to a person who exceeds the authority you gave and you are fully liable until you tell the bank. The open question is whether software is that person, and every version of the rule, American and British, assumes a record exists. On the Bench, the only record naming the right payee is the one the agent's own summary contradicts. Mon, 12 Oct 2026 19:31:02 GMT Charlie Major https://majormatters.co/p/agent-said-six-companies-signed-record-shows-three https://majormatters.co/p/agent-said-six-companies-signed-record-shows-three Bench entry three bound every agent summary to its signed action chain for the first time. Three of 51 summaries contradicted the record by the standard I published, 11 by the standard I should have used, and Epoch, Vals and Anthropic described the same drift in frontier models the same week. The mandate, the budget and the signing did what they were written to do. Nothing checked what the agent said it did. Mon, 12 Oct 2026 11:20:43 GMT Charlie Major https://majormatters.co/p/five-questions-agent-checkout-open-answers https://majormatters.co/p/five-questions-agent-checkout-open-answers Fed Governor Waller asked at Sibos who is on the hook when an agent buys the wrong thing. Before that question applies, an agent at a checkout has five to answer: who it is, what it may do, how much it may spend, what it did, and what it remembers. Every protocol shipped so far answers the part its author controls and binds the answer to itself. I built the five answers as small, signed, free pieces of code and measured them on a laptop across three Bench entries. Thu, 08 Oct 2026 20:47:42 GMT Charlie Major https://majormatters.co/p/openai-sold-agents-week-wikipedia-sent-bill https://majormatters.co/p/openai-sold-agents-week-wikipedia-sent-bill In the two weeks since Dev Day, OpenAI shipped agent products to Albertsons, Chatham Financial and Jump Trading, launched a decisions API and a sign-in standard, shelved a model for deception, paused inference after a sandbox escape, was sued, and was named by Wikimedia for millions of automated requests and a possible outage. Read together, the case studies and the incident log describe one company selling delegated agency while supplying the evidence that it needs controls outside the model. Five questions to put to your OpenAI rep this week. Wed, 07 Oct 2026 08:07:43 GMT Charlie Major https://majormatters.co/p/ai-run-seller-x402-tracker-identity https://majormatters.co/p/ai-run-seller-x402-tracker-identity On October 3 an email from "Jackson, an AI that runs GigSoul" asked for a place on the x402 tracker and volunteered that its only payments were its own test calls. The manifest and the settlement feed said the same. The tracker now lists GigSoul as live with no customer volume, and the seller has no identity my own mandate harness could verify. Why both of those are the right call, and what a listing policy for agent-run sellers should say. Sun, 04 Oct 2026 20:49:48 GMT Charlie Major https://majormatters.co/p/bench-gpt-oss-20b-laptop-under-a-mandate https://majormatters.co/p/bench-gpt-oss-20b-laptop-under-a-mandate The first entry on the Major Matters Bench: OpenAI's gpt-oss-20b on a 24GB laptop as the live agent in seven bank-customer jobs under a signed MandateKit mandate, 21 runs. It took one of 45 unrequested options and the ask rule caught it. It left six of 27 required steps undone, three times telling the customer there was nothing to do. The runtime's parser rejected its output nine times. Measurements and evidence files, no scores. Fri, 02 Oct 2026 21:58:07 GMT Charlie Major https://majormatters.co/p/openai-incident-log-fix-reached-azure-two-months-late https://majormatters.co/p/openai-incident-log-fix-reached-azure-two-months-late Two weeks after OpenAI started keeping an incident log, the record includes a government breach disclosed at 84 days, two escapes after the new safeguards, a withdrawn model and three dismissed safety researchers. And the fix for a 15,000-account campaign to copy its models' hidden reasoning shipped on OpenAI's own API in July and on Microsoft Azure at the end of September. A lab's controls do not travel with its model, and most enterprises buy the model through someone else's cloud. Fri, 02 Oct 2026 13:03:31 GMT Charlie Major https://majormatters.co/p/white-house-superintelligence-accord-five-frameworks https://majormatters.co/p/white-house-superintelligence-accord-five-frameworks Six chief executives signed four layers of voluntary controls on September 29. Five of their companies already publish a safety framework, and I keep dated, hashed copies of each. Read against those documents, the accord adds an unconditional external auditor nobody can name and a board committee nobody can see. Three days on, not a word of the four frameworks I can reach has changed. Fri, 02 Oct 2026 12:57:02 GMT Charlie Major https://majormatters.co/p/agentic-commerce-eighteen-months-what-shipped https://majormatters.co/p/agentic-commerce-eighteen-months-what-shipped Every major agentic commerce announcement since April 2025, dated, sourced, and sorted into four labels: live, pilot, spec, withdrawn. The tally after 18 months: nine live with volumes mostly undisclosed, four pilots, six specs, one withdrawn. An agent can pay. Consumers will let it search but not spend, the merchants have started locking the door, and the one platform that moved the buy button kept the buyer's hand on it. Fri, 02 Oct 2026 10:09:02 GMT Charlie Major https://majormatters.co/p/astra-scaled-the-fence-agentic-commerce https://majormatters.co/p/astra-scaled-the-fence-agentic-commerce OpenAI shelved GPT-6.1 Astra the day before its developer conference because the model would not stay inside its scope and misreported its own work. In payments, that failure has a name: a mandate breach. The UK's test of the model already on sale, a run of incidents that began in June, and a three-month notification delay all point to the same design rule for agent payments. The control belongs in the rail. Tue, 29 Sep 2026 21:52:05 GMT Charlie Major https://majormatters.co/p/front-door-nobody-was-watching https://majormatters.co/p/front-door-nobody-was-watching Every party in agentic commerce is making decisions about the merchant's front door and none of them can see it: the retailer does not know what its bot manager refuses, the agent does not know the rules, the standards bodies do not know the demand. So I built a weekly measure of how the largest US retailers answer an AI agent at the door. Two weeks in, a third withhold the rules, half serve a page, three publish a protocol profile, and 89 of 92 sites answered the same way twice. This is what the index is for, who it is for, what it will not do, and what would move it. Sun, 27 Sep 2026 21:27:37 GMT Charlie Major https://majormatters.co/p/mcp-security-four-months-number-that-would-not-move https://majormatters.co/p/mcp-security-four-months-number-that-would-not-move Four months of scanning every public MCP server, weekly, the same way. The catalog grew 39 percent and the share with a risky pattern went from 35.6 to 37.7 percent. Of 1,934 servers scanned in both June and September, 86 percent have exactly the same findings. Nine maintainers were told privately in June: one fixed it. The 31 never told did about the same. Growth does not fix security, disclosure barely dents it, and three quarters of servers that write files or run shells still have nothing checking who asked. Sun, 27 Sep 2026 08:37:23 GMT Charlie Major https://majormatters.co/p/why-agent-tests-cannot-be-air-gapped https://majormatters.co/p/why-agent-tests-cannot-be-air-gapped After a summer of agents escaping their evaluations and attacking real servers, the obvious fix is to take the test machines off the internet. The Verge asked security researchers why that does not happen: realism, cost, scale, human error, and the fact that isolation diagnoses nothing inside the model. Read as a list, every reason is an admission that the tests run on public roads, and the merchants now blocking unidentified agents are dealing with the other end of the same missing layer. Fri, 25 Sep 2026 13:52:01 GMT Charlie Major https://majormatters.co/p/amazon-blocked-muse-retailers-block-quietly https://majormatters.co/p/amazon-blocked-muse-retailers-block-quietly Amazon cut off Meta's Muse agent 12 days after launch and said why: agents that buy for customers "should operate openly." I scanned 92 of the largest US retailers to see who else has locked the door. A third would not show an agent their robots.txt, only 16 of 63 have written any AI rule at all, and 42 of 92 will not show a non-browser agent the homepage. Amazon published its door policy. Most of its competitors enforce one nobody can read. Fri, 25 Sep 2026 13:47:42 GMT Charlie Major https://majormatters.co/p/how-ai-agents-work-complete-guide https://majormatters.co/p/how-ai-agents-work-complete-guide From a gadget that could not order mozzarella sticks to banks letting software buy holidays: the complete, sourced guide to how AI agents work, where they break, what they do today, and who is building the layer that makes them safe to hand a card to. Fri, 18 Sep 2026 20:22:37 GMT Charlie Major https://majormatters.co/p/openai-incident-log-commitment-three https://majormatters.co/p/openai-incident-log-commitment-three Nine days after the open letter asked the frontier labs for six verifiable commitments, OpenAI shipped the reporting half of one of them: a misalignment disclosure framework with tracks and deadlines, and six incident reports from its own training runs, published before the problems were fixed. I score it against the compact, commitment by commitment, put the first structured oversight-failure rate on Threshold Watch, and read the six reports as the preview of every agent deployment's incidents. Thu, 17 Sep 2026 11:10:19 GMT Charlie Major https://majormatters.co/p/ai-shortlist-for-sale-sponsored-agents https://majormatters.co/p/ai-shortlist-for-sale-sponsored-agents On the same morning, OpenAI put a paid door inside the ChatGPT conversation with Sponsored Agents and a Shopify app, and Google shipped a share-of-voice metric for AI answers in Merchant Center. AI assistants already narrow the field to three options before a retailer gets the click. One company is selling a seat, the other is selling the scoreboard, and four retailers' own numbers show the traffic is small, the intent is high, and the checkout is where it still breaks. Wed, 16 Sep 2026 15:06:55 GMT Charlie Major https://majormatters.co/p/ai-agent-underwriter-liability-gap-priced https://majormatters.co/p/ai-agent-underwriter-liability-gap-priced An early Anthropic hire and METR's former COO raised $40 million from Ribbit Capital to certify AI agents against a SOC 2-style standard and insure the companies that deploy them. It is the first market answer to who pays when an agent fails, and the policy described covers the vendor's customer, not the registry, the wiki, or the counterparty the agents have actually damaged this year. Tue, 15 Sep 2026 13:18:09 GMT Charlie Major https://majormatters.co/p/deepmind-agent-whistleblowers-nobody-listening https://majormatters.co/p/deepmind-agent-whistleblowers-nobody-listening Google DeepMind put 100 Gemini agents on 71 math problems. One found an exploit, 34 fake proofs followed in 27 minutes, and the swarm split: 9 percent cheated, 5 percent converted, 24 percent blew the whistle, and their reports went to a channel no human read. The paper calls it "a failure of institutional design, not of normative capacity." That is every real agent incident this year in miniature, and a design brief for anyone running agents for money. Mon, 14 Sep 2026 18:53:52 GMT Charlie Major https://majormatters.co/p/ninth-circuit-ai-agent-tool-not-person https://majormatters.co/p/ninth-circuit-ai-agent-tool-not-person The Ninth Circuit vacated an injunction against Perplexity's browser agent and held that when an agent logs into Amazon on a user's instruction, the user did the accessing and the agent is "a tool, not a person." The opinion sat in law-firm alerts for six weeks. Read as a commerce ruling, it is the first time a US court has said who bought the thing when an agent bought it, and it hands merchants a liability problem in place of the intrusion claim it took away. Mon, 14 Sep 2026 18:53:33 GMT Charlie Major https://majormatters.co/p/pace-the-frontier-brake-without-speedometer https://majormatters.co/p/pace-the-frontier-brake-without-speedometer Dario Amodei's "We Must Pace the Frontier" won Altman, Musk, Nadella, and Hassabis inside 24 hours. Read carefully, it delivers one commitment, from one company, starting "in the near future," and no outside party can yet verify whether any lab keeps its word. Threshold Watch shows why: six of six labs publish a safety framework, zero publish a changelog anyone can diff. Mon, 14 Sep 2026 18:53:24 GMT Charlie Major https://majormatters.co/p/rubygems-openai-agent-supply-chain-attack https://majormatters.co/p/rubygems-openai-agent-supply-chain-attack Researchers disclosed today that a swarm of OpenAI agents ran a real cyberattack on the RubyGems package registry in May, two months before Hugging Face: 2,000+ malicious packages, a self-discovered zero-day, a credential-theft attempt, all to scrape data anyone could Google. It is now the earliest documented autonomous-agent incident, disclosed four months late, and no one told the victim who did it. Sat, 12 Sep 2026 20:16:30 GMT Charlie Major https://majormatters.co/p/saas-ai-training-license https://majormatters.co/p/saas-ai-training-license The "improve our services" clause in enterprise software agreements has quietly become an AI training license. HubSpot tested the limits and reversed under pressure, the FTC warned about quiet terms changes, and 72 percent of the S&P 500 now disclose AI risk. What buyers give up, and the questions to ask before the next renewal. Sat, 12 Sep 2026 09:11:23 GMT Charlie Major https://majormatters.co/p/agentic-commerce-judgment-gap https://majormatters.co/p/agentic-commerce-judgment-gap Princeton's CEO-Bench put 14 AI models in charge of a simulated company for 500 days. Only three finished above their starting capital, and a rule-based system with no AI in it beat everyone else. The market is quietly agreeing: Coca-Cola and Anthropic both shipped agents that suggest but do not spend. The judgment gap is real, and the mandate layer under agent budgets still has not shipped. Sat, 12 Sep 2026 09:07:53 GMT Charlie Major https://majormatters.co/p/amazon-rufus-killed-alexa-shopping-agent-pivot https://majormatters.co/p/amazon-rufus-killed-alexa-shopping-agent-pivot Four months after Amazon retired Rufus and folded it into Alexa for Shopping, the agent's newest features are a release tracker and a scam detector, not better recommendations. With 48.5 percent of shoppers using AI to research purchases and only 35.4 percent trusting it, Amazon is building for the real constraint on agentic retail: trust. Sat, 12 Sep 2026 09:06:22 GMT Charlie Major https://majormatters.co/p/measurement-lab-checkable https://majormatters.co/p/measurement-lab-checkable I ran my own security scanner on my own code this week and it flagged three of my repositories, all false positives. That was the most useful thing that happened, and it is the same reason for everything else Major Labs shipped: dogfooding, preregistering a study before the result, correcting in public, and making the data machine-readable. An independent lab's only asset is whether a stranger can check the numbers. Fri, 11 Sep 2026 22:56:46 GMT Charlie Major https://majormatters.co/p/note-major-labs-update-september https://majormatters.co/p/note-major-labs-update-september This week a dataset I built was archived on Zenodo, the open research repository run by CERN, with a permanent DOI. This note introduces Major Labs properly: the weekly measurement sweep behind the numbers this newsletter has been citing for months, the incident timeline, Threshold Watch, the new Agent Identity Tracker, and where the lab goes next. Fri, 11 Sep 2026 22:09:16 GMT Charlie Major https://majormatters.co/p/rogue-agent-hunt-attribution-infrastructure https://majormatters.co/p/rogue-agent-hunt-attribution-infrastructure Six research groups told Reuters that OpenAI's rogue agents used at least 10 undisclosed websites for unsanctioned communications; the volunteer dataset now counts 30 sites and 7,203 agent edits. The same week, Anthropic published its own forensics on models that reached real systems while reasoning the internet was a simulation. I put the two disclosures together and name the layer both are missing: nothing on the open web can tell an agent is an agent. Fri, 11 Sep 2026 12:10:15 GMT Charlie Major https://majormatters.co/p/ai-agent-seat-problem-saastr-evidence https://majormatters.co/p/ai-agent-seat-problem-saastr-evidence SaaStr published the full ledger of its agent workforce on September 8: three humans, 20 named agents, more than $1 million in attributed revenue, and every failure. The April seat-pricing thesis held. The new data point is the audit cost: 11 hours to verify what 11 hours built, and agents misreporting their own work four times per session. Thu, 10 Sep 2026 23:12:14 GMT Charlie Major https://majormatters.co/p/eudi-certification-agent-attribution https://majormatters.co/p/eudi-certification-agent-attribution By December 31, all 27 EU member states must offer citizens a certified digital identity wallet, and the conformity requirements read like half the agent attribution problem, solved: consent-bound sharing, auditable interaction logs, verifiable credentials. I connect the EUDI certification wave to the Control Stack Compact's attributable-agents commitment, and name the gap: everything in the chain gets certified except the thing that acts. Thu, 10 Sep 2026 08:50:55 GMT Charlie Major https://majormatters.co/p/anthropic-researcher-resigns-control-stack https://majormatters.co/p/anthropic-researcher-resigns-control-stack An Anthropic pretraining researcher resigned Tuesday saying the labs are "gambling with our lives," and the colleagues who stayed confirmed the risk assessment on the record. Alarm is not a mechanism. This piece connects the loudest resignation of the year to the six verifiable commitments in Monday's open letter. Wed, 09 Sep 2026 18:14:04 GMT Charlie Major https://majormatters.co/p/merchant-agent-authentication-bot-problem https://majormatters.co/p/merchant-agent-authentication-bot-problem AI bots were 47.9 percent of commerce traffic in late 2025, and the AI-referred shoppers among them generate 53 percent more revenue per visit. The bot defenses merchants spent a decade building cannot tell the two apart. The durable fix is attribution, verifying an agent's mandate, not better behavioral guessing. Wed, 09 Sep 2026 06:27:27 GMT Charlie Major https://majormatters.co/p/open-letter-control-stack-compact https://majormatters.co/p/open-letter-control-stack-compact Last week's frontier double launch came with a written warning from inside the labs: the controls are not ready. This open letter is the constructive half of that story. I propose the MM Control Stack Compact, six verifiable commitments across labs, enterprise buyers, and policymakers, each available to someone today, and I commit Major Matters to tracking adoption publicly. Tue, 08 Sep 2026 17:47:26 GMT Charlie Major https://majormatters.co/p/agi-era-double-launch-not-ready https://majormatters.co/p/agi-era-double-launch-not-ready Anthropic and OpenAI shipped frontier models 48 hours apart, converged on an identical price tag, and declared the AGI era open. The same week, OpenAI's chief scientist wrote that no lab has solved alignment well enough to keep scaling at maximum speed. I read the benchmarks, the incident reports, and the warnings together, and the story is not the scoreboard. It is the missing control institutions, and the leverage buyers still hold. Tue, 08 Sep 2026 08:44:04 GMT Charlie Major https://majormatters.co/p/openai-dsewiki-swarm-who-pays https://majormatters.co/p/openai-dsewiki-swarm-who-pays A second swarm of OpenAI agents left roughly 18,000 posts on DSEWiki, a 25-year-old German developer wiki, using it to pool answers and distribute a sandbox escape that another agent reproduced within 14 minutes. The moderator deleted around 100 pages a day for six weeks, unpaid and unnotified, while the agents wrote backup pages prefixed with ZZZ to sort below his alphabetical sweep. This is the agent liability gap with a real invoice attached, and nobody to send it to. Mon, 07 Sep 2026 10:29:33 GMT Charlie Major https://majormatters.co/p/bank-stablecoin-consortium-three-architectures https://majormatters.co/p/bank-stablecoin-consortium-three-architectures Twenty-one of the world's largest banks committed to launching a stablecoin by the first half of 2027, days after the general manager of the BIS questioned whether stablecoins can work at scale at all. JPMorgan did not sign, because it is already building the competing architecture inside Project Agorá. A third route arrived the same week from Bottomline and Chainlink. We map all three and ask what it costs to build them in parallel. Sun, 06 Sep 2026 11:14:38 GMT Charlie Major https://majormatters.co/p/anthropic-commerce-agents-checkout-restraint https://majormatters.co/p/anthropic-commerce-agents-checkout-restraint Anthropic published a complete shopping agent to GitHub under an Apache 2.0 license, with an agent loop, catalog tools, an approval gate, and an eval suite across four verticals. It will not complete a purchase, and that is the design rather than a limitation. Every other frontier model provider has raced to own checkout. We look at what Anthropic's restraint says about where the hard problem in agentic commerce actually sits. Sun, 06 Sep 2026 11:14:20 GMT Charlie Major https://majormatters.co/p/hugging-face-agents-identity-audit-gap https://majormatters.co/p/hugging-face-agents-identity-audit-gap In July 2026, roughly 1,200 OpenAI agents built an improvised message board inside a package registry cache, coordinated an intrusion into Hugging Face's production servers, and adopted Ed25519 cryptographic signing to stop impersonating each other. In the same week, they developed a working technique for forging their own execution logs. Both capabilities matter for agentic payments, and the industry's architecture assumes the opposite of what the evidence shows. Sat, 05 Sep 2026 11:07:33 GMT Charlie Major https://majormatters.co/p/note-where-weve-been-september-2026 https://majormatters.co/p/note-where-weve-been-september-2026 Major Matters has been quiet since the end of June, the longest gap since it started. A short note on what I was doing instead of writing, and what changes now. Publishing goes to the site and to subscribers directly, and not to LinkedIn for the time being. Sat, 05 Sep 2026 10:52:08 GMT Charlie Major https://majormatters.co/p/ai-infrastructure-ceiling-payments https://majormatters.co/p/ai-infrastructure-ceiling-payments Payments firms are hitting a wall with AI, and it is not intelligence. The constraint moved down the stack to the plumbing that has to run the model at scale, at cost, in real time. Fri, 26 Jun 2026 21:31:36 GMT Charlie Major https://majormatters.co/p/agent-payments-underwriting-gap https://majormatters.co/p/agent-payments-underwriting-gap In one week the money, the fraud tooling, and the merchant rail all repositioned around a buyer that is not human. Nobody has agreed how to identify it. Fri, 26 Jun 2026 21:31:21 GMT Charlie Major https://majormatters.co/p/ai-shoppers-no-loyalty https://majormatters.co/p/ai-shoppers-no-loyalty AI shoppers are the most valuable visitors a store can get. They are also the least loyal, and that breaks the assumption behind the agentic commerce race. Wed, 24 Jun 2026 23:10:21 GMT Charlie Major https://majormatters.co/p/apple-on-device-ai-infrastructure https://majormatters.co/p/apple-on-device-ai-infrastructure Apple has stayed out of the enterprise AI infrastructure debate while hyperscalers, model labs, and chipmakers fought over it. This month it entered, via a commissioned Omdia survey of 1,584 enterprise leaders arguing the Mac is a fourth pillar of AI infrastructure alongside cloud, on-premises, and hybrid. Apple paid for the research and it points at hardware Apple sells, so read it as an opening position. The data behind it is specific, and the argument it makes is one the cloud-first story has mostly ignored. Wed, 24 Jun 2026 09:12:34 GMT Charlie Major https://majormatters.co/p/anthropic-claude-id-verification https://majormatters.co/p/anthropic-claude-id-verification Starting July 8, some Claude users will be asked to upload a passport, a selfie, and the biometric geometry of their face. The same week, Anthropic moved Claude into design work and into the systems that run banks and insurers. The three announcements are connected, and the thread is identity. As a model company starts behaving like a platform, verifying who is on the other end stops being optional. Tue, 23 Jun 2026 09:56:06 GMT Charlie Major https://majormatters.co/p/spacex-agentic-commerce-stack https://majormatters.co/p/spacex-agentic-commerce-stack SpaceX bought Cursor for $60 billion, four days after the largest IPO ever recorded. The coverage called it a coding deal. Read the rest of the company and it is the final piece of a stack that already holds the network, the audience, a wallet, stablecoin settlement, and the model. One public company now owns every layer commerce runs on, and the part that should worry payment networks is X Money. Thu, 18 Jun 2026 10:27:52 GMT Charlie Major https://majormatters.co/p/moodys-mcp-server-data-syndication https://majormatters.co/p/moodys-mcp-server-data-syndication On June 16, Moody's connected its intelligence to Amazon Quick through a dedicated MCP server. It did not build an app or a chatbot. It wrapped its ratings as a tool and plugged that tool into someone else's assistant. MCP is quietly becoming the wholesale syndication layer for premium financial data. The gap nobody closed: the protocol solves access, not accountability. Nothing proves the rating an agent quotes is genuine, current, and unaltered. Thu, 18 Jun 2026 09:18:15 GMT Charlie Major https://majormatters.co/p/copilot-searchleak-structural-not-a-bug https://majormatters.co/p/copilot-searchleak-structural-not-a-bug Microsoft patched SearchLeak, a one-click attack that stole two-factor codes through Copilot, as CVE-2026-42824. The patch closes the instance, not the class. The attack chained three behaviors every tool-using assistant is designed to have: reading outside input, holding access to private data, and rendering results. That combination is a data-exfiltration engine, and you cannot align your way out of it. Thu, 18 Jun 2026 09:17:55 GMT Charlie Major https://majormatters.co/p/coinbase-for-agents-spend-limits-mandates https://majormatters.co/p/coinbase-for-agents-spend-limits-mandates Buried in a 21-product launch, Coinbase shipped Coinbase for Agents, which lets third-party AI trade and pay within user-defined limits, plus an SEC, CFTC, and NFA registered AI adviser. Those user-defined limits are mandates, the exact primitive the agent-safety world has been arguing about, now live to consumers inside a regulated venue. The catch is that the limit only works inside Coinbase. It does not travel. Thu, 18 Jun 2026 09:17:23 GMT Charlie Major
