/**
 * Union type representing all possible preliminary validation categories.
 *
 * This type enumerates the different kinds of items that can undergo
 * preliminary validation before major pipeline operations. Preliminary
 * validation ensures consistency between what currently exists in the system
 * and what AI agents are requesting to create or modify, preventing duplicate
 * generation, maintaining referential integrity, and catching inconsistencies
 * early.
 *
 * The validation categories are divided into two groups:
 *
 * **Current Generation Items** (items being created in the current iteration):
 *
 * - **analysisSections**: Requirements analysis document sections
 * - **databaseSchemas**: Prisma database schema models and tables
 * - **interfaceOperations**: API endpoint operations and routes
 * - **interfaceSchemas**: OpenAPI schema type definitions (DTOs)
 * - **realizeCollectors**: Implementation collector functions for data fetching
 * - **realizeTransformers**: Implementation transformer functions for data
 *   processing
 *
 * **Previous Generation Items** (items from prior iterations that may need
 * reconciliation):
 *
 * - **previousAnalysisSections**: Requirements sections from previous iterations
 * - **previousDatabaseSchemas**: Database schemas from previous iterations
 * - **previousInterfaceOperations**: API operations from previous iterations
 * - **previousInterfaceSchemas**: Schema definitions from previous iterations
 *
 * **Control Signal**:
 *
 * - **complete**: Signals that the write loop should be finalized, accepting the
 *   most recent write as-is
 *
 * The "previous" categories enable incremental updates and regeneration
 * scenarios where new requirements need to be merged with or replace existing
 * generated artifacts, ensuring smooth evolution of the generated backend
 * without losing previous work or creating conflicts.
