A demonstration kitchen,
not a restaurant.

This is a publication about agentic payments — software that spends money on a person's behalf — built the way the thing it describes works.

Most publishing ships finished dishes: presentation and meaning fused, one shape for every reader. This site ships Cuts — atomic, schema'd, open-licensed primitives of operator thinking. One idea, one screen, one breath, dated and signed. The corpus of Cuts is the Spine. Everything else you see here — the Plates, the Bestiary, the parables and receipts — is a Surface: one possible rendering of the Spine, plated by me to prove the format.

I provide the best meat cut and they cook, because everyone likes the data in a different way.

I author one signature Surface per format. Your agent does the rest. Every page carries prompts for exactly that — and if you don't use an agent, the authored Surfaces are a complete meal on their own.

How to read this site

Start with the reference pair: Plate II dissects a UPI payment end to end; Plate III does the same for a card purchase. You half-know both flows already — which is the point. On familiar material you can judge the format itself: what the dissection tables show, what the two clocks separate, what the prompts let you rebuild. One UPI specimen yields a creature, a plate, and a receipt; one card specimen yields a plate, a dialogue, and a parable. Two spines, six dishes — the thesis performed rather than argued.

From there: the Counter holds recent Cuts by type. The Field Journal is dated sightings. The Lexicon pins the vocabulary down, and the Atlas maps the primary sources.

For your agent

Every Cut has a machine twin at /cuts/{id}.stock.json: same meaning, presentation deleted. The whole corpus streams from /spine.jsonl, byte-stable across builds so caches hold. /llms.txt explains the format; /graph.json carries the relations. Everything is CC-BY-4.0 and Ed25519-signed — attribution that survives mixing, freshness you can verify, a corpus agents can trust. Verify signatures against /.well-known/agenticpayments.json.

Voice

Rules this site is written under: one idea per Cut. Operator voice — things done and seen, not things imagined. Claims carry dates; numbers with short half-lives are avoided or marked. Provenance is declared (first-hand, sourced, or synthesised). When something stops being true, it is superseded, never silently edited.

Licensing

Content is CC-BY-4.0 — republish, remix, feed it to anything; cite the canonical URL. Code is MIT, public, at GitHub. Each stock file includes a suggested_citation.
