Infrastructure Architecture

• Infrastructure Independence — why ops/my-server/ lives in this monorepo, and how one-playbook-per-application is enforced.
• Decision Records — secrets management (ADR-1), release-tag deployment (ADR-2), and production email sending (ADR-3), in Constitution §16.3 format.
• Deployment Strategy — the broader provider-independence principles (DNS as the public contract, provider evaluation criteria, migration matrix) these decisions operate within.
