## Summary
- Create `docs/explanation/` directory with index and three explanation articles
- why-gitops: Philosophy of GitOps for homelabs (memory, rollback, AI context)
- architecture: How pieces fit together (ASCII diagrams of hosts, data flow, secrets)
- security-model: Tailscale zero-trust, 1Password secrets, access control philosophy
- Update docs/index.md with How-to and Explanation section links
- Update exploring-the-docs to link Explanation section

Decision log deferred to future work.

## Deployment and Testing
