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 the core primitives (nodes, interfaces, relationships, controls, flows), regulatory evidence mapping (DORA, PCI DSS, MAS TRM, APRA CPS 234, HKMA TM-G-1, OSFI B-13, SWIFT CSCF), an Ubuntu 26.04 install guide, the official conference-signup tutorial with a self-hosted CALM Hub, and a glossary. Commands, versions, and clause citations were verified against primary sources as of July 2026 (spec release 1.2, CLI 1.47).
