+# Claims and Roles Guidelines
+
+To ensure consistency across the application, all claim and role values MUST be in lowercase.
+
+## Roles
+The following roles are currently used in the system:
+- `administrator`
+- `manager`
+- `client`
+- `provider`
+- `developer`
+
+## Implementation Notes
+- **Processing**: The `authStore.js` automatically converts all roles extracted from JWT tokens to lowercase.
+- **Comparisons**: All checks (e.g., `authStore.hasAnyRole(['role-name'])` or `meta: { roles: ['role-name'] }`) should use lowercase strings.
+- **Routing**: Route guards in `router.js` expect lowercase role names in the `meta.roles` field.
