Ardalis Result<T> carried incoherent success sub-statuses and a clunky generic converter; ErrorOr models success-or-errors cleanly. - Application: all commands/queries/handlers now return ErrorOr<T> (non-generic Result -> ErrorOr<Success>); errors via Error.NotFound/ Conflict/Validation/Unauthorized/Failure; success via value or new Success() - Drop ResultExtensions.As<>(): error propagation is now just return .Errors - Rewrite HTTP mapping (ErrorOrHttpExtensions) off Error.Type; success maps to 200 (value) or 204 (Success); Created still built in the endpoints - Endpoints/gateway middleware: !IsSuccess -> IsError - Swap Ardalis.Result package for ErrorOr 2.1.1 (remove unused ref from Worker) Build: 0 warnings, 0 errors.
