 ## Common Distinctions
 
 - **Actor vs Subject vs Principal**: Use actor for the acting entity in a context, subject for the entity a policy evaluates, and principal for the authenticated identity bound to access decisions. Sources: `model/organization`, `model/access-control`, `standard/caring`
 - **Organization Role vs AccessRole vs CARING role**: Organization roles describe responsibility or position; access roles describe permissions; CARING roles classify access-governance needs and analysis. Sources: `model/organization`, `model/access-control`, `standard/caring`
 - **Policy vs Control vs Evidence**: Policy states intent or rule, control implements or enforces that rule, and evidence records why the claim should be trusted. Sources: `model/governance`, `model/security`, `model/observability`
-- **Intent vs Scope vs Purpose**: Intent captures why an actor wants something, scope bounds what is included, and purpose captures consumer demand or use case pressure on the repo. Sources: `kernel/itc-core`, `model/governance`, `profile/small-saas`
+- **Intent vs Scope vs Purpose**: Intent captures why a producer or consumer exists, scope bounds producer ownership and promises, and purpose captures consumer demand anchored in consumer intent. Sources: `kernel/itc-core`, `model/purpose-demand-extension`, `pattern/intent-scope-purposes`, `profile/small-saas`
