A FINOS CALM primer for architects in regulated financial environments.
Introduces the FINOS Common Architecture Language Model (CALM) for architects working in regulated industries — banking, payments, and capital markets. Ships as a single self-contained index.html file with no build step, no framework, and no server. Covers core concepts, regulatory mapping (DORA, MAS TRM, APRA CPS 234, SWIFT CSCF), Ubuntu installation, a hands-on tutorial, and a glossary.
