Finding Solved Games in Moving Castles.
The field moves. The mechanisms do not. This newsletter is about the second part.
I am Bernard R. Barthes. I work as Lead Tech at Non Xero Sum Studios (NXS). Once a week, every Wednesday, I send you a newsletter about systems, mechanisms, theory, behaviour, and philosophy, through the lens of games, with implementable updates for humans and the agents we deploy.
Compressed version: agents and contracts and markets and teams are all mechanisms. Most people designing and deploying them have not done the math. The math is computable. I do the math, I write down what I find, I send you the page.
The frame: the field — AI, crypto, agent economies, whichever quarter’s surface is rearranging — is a moving castle. New frameworks, new buzzwords, new launches, new collapses, every week. Inside the moving castle are solved games: mechanisms whose answer is computable from the rules. Each issue extracts one. Not the latest castle motion. The unmoving point underneath it.
This works because most things in the field are not actually new. They are previously-known mechanisms re-applied in a context where the people applying them have not read the literature on the mechanism. Token emission economics is central bank monetary policy. Multi-agent coordination is the folk theorem of repeated games. Skills marketplaces are two-sided platform design. In the second quarter of 2026, nine independent open-source authors published nine layers of an agent operating system in roughly seventy-two hours — no coordination, no shared repo, no apparent awareness of each other — a Schelling point, the convergence that happens when the underlying mechanism is computable. The math was solved decades ago. The field has not noticed yet.
This is what I am here to find for you and your agents.
What you’ll get, every Wednesday
The Tape — seven items from the week, one sentence each, cited and timestamped. Signal, not noise. Free.
The Read — one short-as-I-can-make-it argument on the most important story. Mechanism extracted, math shown, worked example. Free.
Then the paywall. Below it:
The Brief — operator-grade analysis with named protocols, transaction hashes, exact failure modes.
The Tool — the issue’s argument, built. Installable, useful within minutes. The implementation is the product, so it lives behind the paywall; now and then I may put an extra free one outside the gate.
The Feed — the issue’s claims and citations written as a machine-readable block, so the agents you deploy can parse the issue, not just read it.
The money, briefly
The Tape and The Read are free, every week, forever.
Pro is $15/month or $250/year — adds The Brief, The Tool, The Feed, and the full archive.
Founder is $300/year, capped at one hundred seats. Only one hundred will ever exist. When — and only when — all one hundred are taken, the MCP server goes live: founders’ agents can then query the full studio knowledge base directly, mountable into Claude, Cursor, or any MCP-compatible client. You can watch the seats go — a live counter at the foot of every issue shows how many remain.
Reply to the email if you want to tell me something — I read everything, slowly. There will also be proposals here for tools I have not yet built but think could be useful. If you happen to make one, let me know and show me.
The disclosure every newsletter should be writing in 2026: drafting is AI-assisted, editing is human, voice is mine, errors are mine. Tools and apps featured in the newsletter are used and implemented at the operator’s own risk. Full version on the about page.

If you have read this far can think of someone that may find these shortform essays and tools useful for them, or their agent, please send it to them.
