+// Saved Views routes
+// - CRUD operations for saved views
+// - Requires appropriate permissions via requirePerm middleware
+// - Supports filtering and pagination on list endpoint
+// - Uses ownerResolvers utility to determine org ownership for permission checks
+// - Permissions required are defined in config/permissions.js
+//   - savedview.read
+//   - savedview.create
+//   - savedview.update
+//   - savedview.delete
+// - Scope can be 'global' (list), 'org' (get/create/update/delete)
+// - List endpoint supports filtering by project_id, org_id, shared flag, and search query (q)
+// - Pagination via limit and offset query parameters
+// - Results ordered by id DESC
+// - Error handling for not found and no fields to update scenarios
+// - Uses async/await for asynchronous operations
+// - SQL queries use parameterized queries to prevent SQL injection
+// - Responses are in JSON format
+// - Middleware functions are used for permission checks
+// - Owner resolvers are used to fetch org_id for specific view ids
+// - Code is modular and organized for maintainability
+// - Comments are provided for clarity/documentation
+// - Follows best practices for Express.js route handling
+// - Uses ES6+ features for cleaner code
+// - Assumes existence of saved_views table with appropriate columns
+// - Assumes existence of users table for owner
+// - Assumes existence of config/permissions.js with defined permission codes
+// - Assumes existence of utils/scope.js with buildScopeWhere and ownerResolvers functions
+// - Assumes existence of middleware/requirePerm.js for permission checks
+// - Assumes existence of db/index.js for database connection/querying
+// - Assumes Express.js app is set up to use this router for /api/saved_views path
