Policy Scopes

Policy scopes describe where semantic policies are attached in the system graph.

At the structure level, a policy scope identifies which observer model, boundary, entity model, process graph, relation model, projection model, transition, or effect a policy governs. Policy scopes explain where a command is accepted, rejected, routed, delayed, retried, compensated, or interpreted differently by different observers. This describes decision scope and meaning, not a specific policy engine or enforcement substrate.

Policy scopes may cover:

• Authority and permissions.
• Validation rules.
• Routing decisions.
• Retry and rate-limiting behavior.
• Coordination choices.
• Retention and replay.
• Recovery and compensation.

Policies are observer-relative when they affect command interpretation inside a specific observer boundary.
