The web now has a first reader, and it isn’t human.

A Senteri Briefing The single number that describes June 2026 better than any other is nineteen. That is how many days passed between the United States government ordering Anthropic to switch off its two most capable models — and those models being back, globally, as…

I did not set out to build an MCP gateway. I set out to stop editing a glossary through a WordPress form. What follows is the honest path between those two points — the decisions, the double-booked permissions, the questions I still have not fully answered. It is one…

A Senteri follow-up. The question hasn’t changed. The menu has. On June 10, I published a field-report about Claude Fable 5 — how, the moment I brought it real defensive-security questions, it quietly handed me to a weaker model, Opus 4.8, and told me so. The thesis…

A field note on what a year of AI-and-jobs predictions actually told us — and why the predictions turned out to be the least reliable thing in the room. For about a year, the people building AI told us it was coming for our desks. Not in the hedged, someday-maybe…

For the first time there’s crawl-scale data on what structured markup the web actually carries — and it says the machine-readable web is narrower, more automated, and more out-of-date than anyone admits. We have spent two years arguing about how to make websites…

Field report from the Governance layer of agent-readiness — the business decisions sitting on top of all the technical work, now that most of your traffic isn’t human. Here is the number that ends the argument about whether this matters yet. As of June 2026,…
