# ClaimTaskValidator

A FluentValidation validator for `ClaimTask` that extends the shared `TaskValidator<ClaimTask>` base rule set (due date and text) with claim-task-specific rules: the claim number must reference an existing claim, the assigned task user must be a valid/authorized mail ID unless it is the special "INFO" user or a configured task group, and the task date must fall within the next two years when it has changed and the user is not "INFO". It depends on `ITaskService` (to check claim validity and user edit authorization) and `IWorkCalendarService` (passed through to the base validator).

## Purpose
- Confirms `ClaimNumber` corresponds to a real claim via `ITaskService.IsValidClaim`.
- Confirms the assigned `TaskUser` mail ID is valid/authorized via `ITaskService.CanUserEdit`, except for the reserved "INFO" user or task-group IDs listed in `ITaskService.ValidGroups`.
- Confirms `TaskDate` is between today and two years from today, but only enforces this when the date has actually changed from `PreviousTaskDate` and the user is not "INFO".

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

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| ClaimTaskValidator(ITaskService, IWorkCalendarService) | `public ClaimTaskValidator(ITaskService taskService, IWorkCalendarService workCalendarService)` | Passes `workCalendarService` to the base `TaskValidator<ClaimTask>` constructor, then registers claim-number validity, task-user authorization (skipped for "INFO" and configured groups), and task-date range rules using `taskService`. |

## Behavioral notes
- The `TaskUser` authorization rule is conditioned with two `.When(...)` clauses: it only runs when the user is not the literal string `"INFO"` and is not one of the configured task-group identifiers exposed by `ITaskService.ValidGroups`.
- The task-date range rule only fires when `TaskDate != PreviousTaskDate`, so re-saving a task without changing its date does not re-trigger the two-year-window check.
- Extends `SAIF.Services.Tasks.TaskValidator<ClaimTask>` (same library), which additionally requires `TaskDate` to be set and fall on a valid working day per `IWorkCalendarService.IsWorkingDay`, and requires `TaskText` to be non-null, non-empty, and no more than 4000 characters; those base rules apply to every `ClaimTask` validated by this class in addition to the rules registered here.
