Domains in Nestr define areas of exclusive control for a role or circle. When a role holds a domain, others must get permission before impacting it, creating clear boundaries that prevent confusion and overstepping.

Policies grant or restrict access to domains, establishing transparent rules for collaboration. Instead of relying on implicit norms or manager approval, policies make expectations explicit and accessible to everyone.
Domains and policies create the guardrails that allow distributed authority to work safely, giving people the freedom to act within their roles while protecting the organisation's critical assets.
