Terraform Atmos Infrastructure

AWS infrastructure for the fnx tenant: Terraform root modules composed into stacks with Atmos, deployed by Atmos workflows locally and Atmos Native CI in GitHub Actions. Operating it (bootstrap, deploy, state, DR) is in docs/OPERATIONS.md.

The repository follows Cloud Posse: when a Cloud Posse component or module already models something, copy its variable names, types and defaults; use typed objects, never map(any); document every deviation in a comment beside the code, naming the upstream source.
