+
+## 🎓 Learning Points
+
+### ObjectStack Protocol
+- Field names must use PascalCase
+- Object names must use snake_case
+- All field types must be from protocol spec
+- Relationships use hasMany/belongsTo/lookup/masterDetail
+
+### Hook Patterns
+- Use TriggerContext for context data
+- Include event property for event-based logic
+- Import db from @hotcrm/core
+- Log important operations for debugging
+
+### Validation Formulas
+- Use ISBLANK() for null checks
+- Use AND/OR for compound conditions
+- Use PRIORVALUE() for change detection (when supported)
+- Keep formulas simple and readable
