# ClaimNoteValidator

A FluentValidation `AbstractValidator<NoteEdit>` that enforces claim-note content constraints: note text is required and capped at 4000 characters, appended text must not push the combined note (including a generated append header) past 4000 characters, and the note's `Category` and `Type` must each individually pass their own dedicated validators (`NoteCategoryValidator`, `NoteTypeValidator`).

## Purpose
- Requires `Text` to be present.
- Caps `Text` at 4000 characters.
- Ensures `AppendText`, when supplied, does not cause the combined text (original text plus append header plus appended content) to exceed 4000 characters.
- Delegates `Category` and `Type` validation to `NoteCategoryValidator` and `NoteTypeValidator` respectively.

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

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| ClaimNoteValidator() | `public ClaimNoteValidator()` | Registers rules requiring non-empty `Text` no longer than 4000 characters, a valid-length `AppendText` (checked via `HasValidAppendTextLength`), and nested validation of `Category`/`Type` via `NoteCategoryValidator`/`NoteTypeValidator`. |

## Behavioral notes
- `HasValidAppendTextLength` computes an estimated append-header length from the update date's short date string length (or a 6-character default), the current user ID length (or a 6-character default), plus 18 fixed characters, then checks that `Text.Length + AppendText.Length + headerLength` is within 4000 and that `AppendText` is non-empty; a `null` `AppendText` is always considered valid.
- A commented-out rule (`AppendText` required when `!CanEdit`) remains in the source but is not active.
