# UC4Service

`SAIF.Services.WCF.UC4.Host.Services.UC4Service` is the sole service class registered by this host, reached through the single `UC4` route. It exposes eight operations — four job-invocation forms (no parameters, JSON string, positional values, key/value pairs) crossed with two identity modes (`UC4Environment` enum, `short` client id) — that gate a caller-supplied job name against an allow/deny rule list and forward allowed jobs to a downstream UC4 scheduling service.

| Field | Value |
| --- | --- |
| **Service class** | `SAIF.Services.WCF.UC4.Host.Services.UC4Service` |
| **Declared contract** | `IUC4Service` — external (`SAIF.Services.WCF.Contracts`, assembly identity not resolvable)* |
| **Route** | `UC4` |
| **Source** | `src/WCF/SAIF.Services.WCF.UC4.Host/UC4Service.cs` |
| **Service attributes** | `[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]`, `[LogErrorBehavior]` (external `IServiceBehavior`) |
| **Instancing / concurrency** | Not declared — WCF defaults (`PerSession` / `Single`) |
| **Binding** | Not configured; `ServiceHostFactory` applies WCF protocol mapping, which maps `http` to `basicHttpBinding` by default* |
| **Class-level authorization** | None in code |
| **Error handling** | `[LogErrorBehavior]` applied — contributes logging, not fault shaping; see [Faults and error pipeline](../faults.md) |
| **Operations** | 8 (4 marked `[Obsolete]`) |
| **Also hosted in** | — registered by exactly one host, on exactly one route name, in exactly one solution |

The contract interface `IUC4Service` is not declared anywhere in this repository. Every operation section below is therefore derived from the public members of this class, not from the contract interface; the caveat is stated once here and not repeated per operation.

## ExecuteJob

*(Obsolete)* Invokes a job identified by a `UC4Environment` enum value with no caller-supplied parameters, by converting the enum to a client id and delegating to `ExecuteJobWithClientId`.

| Field | Value |
| --- | --- |
| **Operation name** | `ExecuteJob` |
| **Contract name** | Not observable — contract assembly is external |
| **SOAP action** | Not observable — contract assembly is external |
| **Implementing member** | `UC4Service.ExecuteJob` (`src/WCF/SAIF.Services.WCF.UC4.Host/UC4Service.cs:139`) |
| **Pattern** | Request/response |
| **Binding** | `basicHttpBinding` (WCF protocol-mapping default)* |
| **Obsolete** | Yes — `[Obsolete("The Enums for Enviroments is not kept up to date, please use method that takes in number for clientID")]` (`UC4Service.cs:138`) |
| **Authorization** | [None in code](../authentication-authorization.md#access-requirements-per-operation) |
| **Process** | [OP-001](../operations/execute-job.md) |

### ExecuteJob input message

| Part | Type | Required | Default | Purpose |
| --- | --- | --- | --- | --- |
| `environment` | `SAIF.Core.Contracts.UC4.UC4Environment`* | Not observable — external contract** | — | Selects the environment; converted internally to a `short` client id |
| `jobName` | `string` | Not observable — external contract** | — | The job to invoke |

### ExecuteJob output message

| Field | Value |
| --- | --- |
| **Return type** | `UC4Result` (`SAIF.Core.Contracts.UC4`)* |
| **Meaning** | The mapped downstream result on success; a default-constructed `UC4Result` when the job is blocked |
| **Empty-result behavior** | A blocked job returns `new UC4Result()` and discards the explanatory message — [BR-UC4-005](../business-rules.md#br-uc4-005-blocked-job-returns-empty-result-with-no-explanation) |

### ExecuteJob faults

| Fault | Declared in host source | Raised when | Surfaced as | Detail crosses the boundary |
| --- | --- | --- | --- | --- |
| Unmapped enum value | No fault metadata visible locally** | `UC4EnvironmentFactory.GetUC4ClientId(environment)` throws for an unmapped value** | Generic SOAP fault produced by the framework | Yes — `includeExceptionDetailInFaults="true"` |
| Delegated failures | No fault metadata visible locally** | Any failure mode of `ExecuteJobWithClientId` | Generic SOAP fault produced by the framework | Yes |

Whether `IUC4Service` declares a `[FaultContract]` for any of these faults is Not observable — external contract**; the host source only shows that no `FaultException` is constructed locally. See [Faults and error pipeline](../faults.md).

### ExecuteJob side effects

| Aspect | Finding |
| --- | --- |
| Records written | None locally — the downstream service may write job-execution state, out of scope |
| Downstream calls | `UC4Client.ScheduleJob` (via delegation to `ExecuteJobWithClientId`) |
| Shared state touched | None |
| Repeat-call behavior | Not idempotent from the host's perspective — each call forwards a new job-execution request to the downstream scheduler |

---
