# ImageDeleteValidator

A FluentValidation `AbstractValidator<ImageDelete>` used by `SAIF.Services.Groups.Imaging.ImageDeleter` (via `IValidationService.ValidateAndThrow`) to ensure a group image exists before it is deleted. It depends on `IGroupImageRepository` to check image existence.

## Purpose
- Enforces that the image group referenced by an `ImageDelete` request actually exists before deletion is permitted.

## Context
- Namespace: `SAIF.Services.Groups.Imaging.Validators`
- Assembly/package: `SAIF.Services` (packaged inside the `SAIF.SAIFCode.Core` NuGet package)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| ImageDeleteValidator(groupImageRepository) | `public ImageDeleteValidator(IGroupImageRepository groupImageRepository)` | Stores the repository and registers a `RuleFor(n => n.ImageGroupId)` rule requiring `groupImageRepository.ImageFound` to return true, with message "Error: Image could not be found." |

## Behavioral notes
- Validation is a single existence check; it does not verify edit authorization (that is handled separately by `ImageEditValidator`/`GroupImageSecurityProvider` for edits, not deletes)*.
