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 — the one invented word you need. A Cut is a single idea in ~180 words: dated, signed, and licensed for reuse. Everything else you see here — the dissections, the field guide, the parables and receipts — is one possible plating of those Cuts, made by me to prove the format.

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

That's the whole arrangement: I author one signature version per format, and your agent does the rest. Every page carries recipes — click one, and it copies the material plus an instruction; paste it into ChatGPT, Claude, or Gemini and the idea is re-cooked into the shape you want. And if you don't use an AI at all, the authored pieces are a complete meal on their own.

How to read this site

Start with the reference pair: the dissection of a UPI payment and the dissection of 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 recipes let you rebuild.

From there: the homepage holds the Cuts, newest first. The journal is dated sightings from the field. The lexicon pins the payments vocabulary down, and sources maps the primary material this site draws on.

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 between Cuts. 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 When something stops being true, it is superseded, never silently edited.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.
