ImageDeleter

Implements IImageDeleter, the group-imaging delete operation invoked by SAIF.Services.Groups.Imaging.ImageService.DeleteImage. It depends on IValidationService to validate the delete request, IGroupImageRepository to perform the actual deletion, and IGroupImageSecurityProvider to stamp the deleting user's ID onto the delete record.

Purpose

• Validates an ImageDelete request before allowing deletion to proceed.
• Deletes a group image by recording a Data.Model.Groups.ImageDelete entry with the current timestamp and user ID.

Context

• Namespace: SAIF.Services.Groups.Imaging
• Assembly/package: SAIF.Services (packaged inside the SAIF.SAIFCode.Core NuGet package)

Public members

Member	Signature	Purpose
ImageDeleter(...)	public ImageDeleter(IValidationService validationService, IGroupImageRepository groupImageRepository, IGroupImageSecurityProvider security)	Wires in the validation, repository, and security collaborators used by Delete.
Delete	public void Delete(ImageDelete imageDelete)	Validates imageDelete (throwing on failure via ValidateAndThrow), then deletes the target image group, recording the deletion timestamp and current user ID.

Behavioral notes

• Delete calls validationService.ValidateAndThrow, which throws rather than returning a message list, so callers must handle validation failures as exceptions rather than as a result object*.
• The actual removal is delegated entirely to groupImageRepository.Delete; this type does not itself manage a unit-of-work transaction boundary — that is the caller's (ImageService.DeleteImage) responsibility*.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
