# Business rules

The only call site enforces a single client-side default: it labels every logged error with a fixed environment name regardless of which deployment track actually produced it.

---

## BR-LOG-001 Environment is hard-coded to NetProd

| Field | Value |
| --- | --- |
| Statement | `SAIFExceptionLogger.Log` always sets `ApplicationExceptionDetail.Environment = "NetProd"` before calling `WriteError`, regardless of the deployment track the code is actually running on |
| Trigger | Evaluated whenever `SAIFExceptionLogger.Log` builds the `ApplicationExceptionDetail` for a caught Web API exception |
| Enforcement | Call site — `SAIFExceptionLogger.cs:23` |
| Origin | call site |
| Outcome | Every error record sent to `WSLogging` from `EnvironmentApi`, in every deployment track, is tagged `NetProd`, so the `Environment` field cannot be used to distinguish which track produced the error |
| Related operation | [`WriteError`](reference.md#writeerror) |
| Reached from | [`WriteError`](reference.md#writeerror) via `SAIFExceptionLogger.Log` (`Services/SAIF.Services.WebApi/EnvironmentApi/App_Start/SAIFExceptionLogger.cs:33`) |
| Source | `Services/SAIF.Services.WebApi/EnvironmentApi/App_Start/SAIFExceptionLogger.cs:23` |
