+        # Compliant getter implementations
+
+        Getters that:
+        - Directly access and return property values
+        - Return a literal value
+        - Compute and return values derived from existing properties
+
+        # Non-compliant getter implementations
+
+        ## Violation: getters that call functions
+
+        Getters that call functions cannot be primed for offline use cases.
+
+        ### Remediation
+
+        Reorganize any getter implementation code that calls a function, to move such calls out of the getter. Avoid invoking any function calls within getters.
+
+        ## Violation: getters with side effects
+
+        Getters that assign values to member variables or modify state create unpredictable side effects and are not suitable for offline scenarios.
+
+        ### Remediation
+
+        Never assign values to member variables within a getter. LWC getters should only retrieve data without modifying any state. If you need to compute and cache a value, perform the computation and assignment in a lifecycle hook or method, then have the getter simply return the cached value.
+
+        ## Violation: getters that do more than just return a value
+
+        Getters that perform complex operations beyond returning a value cannot be primed for offline use cases.
+
+        ### Remediation
+
+        Review the getters and make sure that they're composed to only return a value. Move any complex logic, data processing, or multiple operations into separate methods or lifecycle hooks, and have the getter simply return the result.
