# ImageEditValidator

A FluentValidation `AbstractValidator<ImageEdit>` used to validate agency-image edits before they are applied by `SAIF.Services.Agencies.Imaging.ImageService.EditImage`. It has no injected dependencies, referencing `ImageService.MaxDescriptionLength` directly as a static constant.

## Purpose
- Enforces a maximum description length matching `ImageService.MaxDescriptionLength` (256 characters).
- Requires a category code and a document-type code on every agency-image edit.

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

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| ImageEditValidator() | `public ImageEditValidator()` | Registers `RuleFor(n => n.Text).Length(0, ImageService.MaxDescriptionLength)`, `RuleFor(n => n.CategoryCode).NotNull()`, and `RuleFor(n => n.DocumentTypeCode).NotNull()`, each with a corresponding "Error: ..." message. |

## Behavioral notes
- Unlike the group-imaging `ImageEditValidator`, this validator does not check user-edit authorization or verify the image/category/type/group exist in the repository — those checks are performed inline within `ImageService.EditImage` itself rather than in this validator*.

> **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.
