RTWService

Implements IRTWService, resolving the active return-to-work (RTW) load code assigned to a load user and enforcing that external users can only access RTW claims explicitly assigned to their RTW load code. It depends on IUnitOfWork for repository access to RtwLoadAssignment/RTWCase and on IUserProfileService (exposed as a protected field, though not directly used by its current methods).

Purpose

• Resolves the active (non-expired) RTW load code assigned to a given load user, stripping a "TEST" prefix from the user name before lookup.
• Enforces that a user with the "RTWExternalUpdate" authorization can only access an RTW claim when it is assigned to the load code passed in; internal/non-restricted users are always permitted.

Context

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

Public members

Member	Signature	Purpose
RTWService	public RTWService(IUnitOfWork unitOfWork, IUserProfileService userProfileService)	Stores the unit-of-work and user-profile collaborators as protected fields for use by derived types and instance methods.
GetRTWLoadCode	public string GetRTWLoadCode(string loadUser)	Strips a leading "TEST" prefix from the load-user name, looks up the matching non-expired RtwLoadAssignment, and returns its RTW load code, or an empty string if none is assigned.
CanAccessRTWClaim	public bool CanAccessRTWClaim(long claimId, IApplicationUserProfile currentUser, string rtwLoadCode)	Returns true unconditionally for users without the "RTWExternalUpdate" authorization; for authorized-external users, returns true only if an RTWCase exists for the claim with the matching RTW load code.

Behavioral notes

• GetRTWLoadCode performs a case-insensitive load-user comparison and requires ExpirationDate == null on the assignment, meaning only the currently-active assignment is matched.
• CanAccessRTWClaim gates its restrictive check behind currentUser.IsAuthorized("RTWExternalUpdate"), implying this authorization identifies external RTW users subject to load-code restriction.*
