Here are the classes, structs, unions and interfaces with brief descriptions:

CW25QFlashQSPI	STM32 HAL QUADSPI driver for a Winbond W25Q-series flash chip (Adafruit 5632/5633/5634), operated in indirect mode with QUADSPI's own hardware-managed NCS (see the companion SPI driver, W25QFlashSPI, for why that one manages chip-select manually instead – same underlying command structure, different peripheral capability)
CW25QValidation	Destructive validation suite for a W25QFlashQSPI driver – see w25q_validation.hpp's file header for the full design rationale (adapted from the AS6C4008 SRAM validation suite, with flash- specific adaptations for erase-before-write and finite erase endurance)
Cw25qValidationReport_t	Detailed validation report, persistent for the life of the W25QValidation instance
