Periodic Table of Transactions
Twenty-two elements. One ledger.
Every transaction is a combination of these primitives. A house close mixes identity, statute, asset, settlement, and cognition. A trade mixes identity, match, and settlement. A FHIR update mixes identity, asset, and feed. The combinations are infinite. The elements are 22.

Same shape across pillars
Different industries. Same atom.
A FHIR claim and an ISO 20022 wire and a FIX fill and an OpenBadges credential all decompose into the same handful of primitives — identity, statute, asset, action, cognition. They all emit the same receipt format. Because under the law of physics, the unit is joules; under the law of evidence, the unit is signature.
