SecurityOverrideService

Implements ISecurityOverrideService to create, update, delete, and enrich security-override records for injury claims, coordinating persistence through IUnitOfWork, rule validation through IValidationService, and current-user/claim lookups through IUserProfileService. It maps SAIF.Data.Model.Claims.SecurityOverrides.SecurityOverride entities to the SAIF.Core.Contracts.Claims.SecurityOverrides.SecurityOverride contract via an AutoMapper mapping registered in its constructor, deriving IsConflictClaim from IsWorkerConflict and IsSecureClaim from whether the hostile-worker code is "R" or "T".

Purpose

• Creates and updates security-override records for a claim/employee pair after validating the submitted edit through IValidationService.
• Enriches a security override with computed display data (formatted user name, claim number, worker name) and edit/delete eligibility flags based on effective/expiration dates.
• Deletes an existing security override within a unit-of-work transaction.
• Supplies claim-number and user-ID existence checks (IsValidClaim, IsValidUserId) used as FluentValidation rule predicates by SecurityOverrideValidator.

Context

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

Public members

Member	Signature	Purpose
SecurityOverrideService	public SecurityOverrideService(IUnitOfWork uow, IUserProfileService userProfileService, IValidationService validationService)	Wires the repository/user-profile/validation collaborators and registers the entity-to-contract AutoMapper map for security overrides.
GetSecurityOverrideById	public Core.Contracts.Claims.SecurityOverrides.SecurityOverride GetSecurityOverrideById(long id)	Loads a single security override by its identifier, mapped to the contract type with computed display fields populated.
GetSecurityOverrides	public IEnumerable<Core.Contracts.Claims.SecurityOverrides.SecurityOverride> GetSecurityOverrides(bool includeExpired)	Returns all security overrides, optionally filtering out ones whose expiration date has passed.
CreateOverride	public Core.Contracts.Claims.SecurityOverrides.SecurityOverride CreateOverride(SecurityOverrideEdit securityOverrideEdit, IMessageContainer messages)	Validates the edit, then persists a new security-override record (with hostile-worker code, conflict flag, and audit stamps) in a unit-of-work transaction; returns an empty contract instance when validation fails.
UpdateOverride	public bool UpdateOverride(long id, SecurityOverrideEdit updateOverride, IMessageContainer messages)	Validates the edit, rejects the update as a concurrency conflict if the stored UpdateDate no longer matches, and otherwise persists the new effective/expiration dates and audit stamps; returns whether the update succeeded.
DeleteOverride	public bool DeleteOverride(long id, IMessageContainer messageContainer)	Deletes the matching security-override record in a unit-of-work transaction; returns false if no record is found.
IsValidClaim	public bool IsValidClaim(string claimNum)	Reports whether an injury claim exists with the given claim number (case-insensitive by uppercasing).
IsValidUserId	public bool IsValidUserId(string userId)	Reports whether the given user ID resolves to an application user with a non-empty last name.

Behavioral notes

• CreateOverride, UpdateOverride, and DeleteOverride wrap their writes in IUnitOfWork.Begin()/Commit() (or Rollback() on a detected concurrency conflict).
• UpdateOverride implements optimistic-concurrency checking by comparing the incoming UpdateDate against the stored record before applying changes.
• SetAdditionalProperties* (private) computes CanEdit/CanDelete from the override's expiration/effective dates relative to DateTime.Today.
• Validation is delegated to IValidationService.Validate, with FluentValidation errors added to the supplied IMessageContainer.

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.
