Major Matters decodes the infrastructure being built across payments, AI, and commerce. Infrastructure-first, hype-skeptical, evidence-led.

The Air Gap Is an Admission. Here Is What It Means for 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.
Who Pays When the Agent Pays Wrong? The Rule Is Older Than the Agent.
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.
The Agent Said It Updated Six Companies. The 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.

A Federal Court Just Decided Who Your Shopping Agent Is. It Is You.
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.
An Open Letter on Finishing the Control Stack
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.
The Week the AGI Era Got Announced, and the People Building It Said They Weren't 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.
