# Diagnose

## 1. Purpose  
The `DiagnoseParameters` class encapsulates configuration and state-tracking data for a diagnostic phase within a state machine. It determines how the system transitions out of the diagnostic state—specifically whether to proceed to the real-time operational state—and tracks whether all units have passed their diagnostics. This class serves as a parameter object passed to or managed by the diagnostic state handler, enabling configurable behavior (e.g., strict vs. permissive pass requirements) and runtime status updates during diagnostics execution.

## 2. Public Interface  
- **`class DiagnoseParameters : IStatusParameters`**  
  Implements `IStatusParameters` (interface not shown in source) to provide status-related parameters for a diagnostic state.

- **`bool ProceedToRealtimeWhenDone { get; set; }`**  
  Controls whether the state machine should transition to the real-time state upon successful completion of diagnostics. Default: `true`.

- **`bool RequireAllUnitsPassDiagnostic { get; set; }`**  
  If `true`, the diagnostic phase is considered successful only if *all* units pass; if `false`, the phase may succeed even if some units fail. Default: `false`.

- **`bool AllUnitsPassedDiagnostic { get; set; }`**  
  Reflects the actual outcome of the diagnostic run: `true` if all units passed, `false` otherwise. Initialized to `false`.

- **`void Reset()`**  
  Resets all properties to their default values:  
  - `ProceedToRealtimeWhenDone` → `true`  
  - `RequireAllUnitsPassDiagnostic` → `false`  
  - `AllUnitsPassedDiagnostic` → `false`

## 3. Invariants  
- `AllUnitsPassedDiagnostic` must be set by external logic (e.g., diagnostic execution logic) *before* the state machine evaluates transition conditions based on this flag.  
- `RequireAllUnitsPassDiagnostic` and `AllUnitsPassedDiagnostic` jointly determine diagnostic success:  
  - If `RequireAllUnitsPassDiagnostic` is `true`, success requires `AllUnitsPassedDiagnostic == true`.  
  - If `RequireAllUnitsPassDiagnostic` is `false`, success is assumed regardless of `AllUnitsPassedDiagnostic` (though the exact semantics depend on downstream state machine logic, which is not provided).  
- After `Reset()` is called, all properties revert to their documented default values; no partial resets occur.  
- `DiagnoseParameters` is a mutable class—consumers must be cautious about shared instances and concurrent access (no thread-safety guarantees are implied by the source).

## 4. Dependencies  
- **Depends on**:  
  - `System` (core .NET namespaces: `System`, `System.Collections.Generic`, `System.Linq`, `System.Text`, `System.Threading.Tasks`).  
  - `DTS.DASLib.Service.StateMachine` namespace (same assembly/project), specifically the `IStatusParameters` interface.  
- **Used by**:  
  - State machine logic within `DTS.DASLib.Service.StateMachine` (inferred from namespace and class name), particularly code managing the diagnostic state.  
  - Likely consumed by diagnostic execution components that set `AllUnitsPassedDiagnostic` and by state transition logic that inspects `ProceedToRealtimeWhenDone` and `RequireAllUnitsPassDiagnostic`.

## 5. Gotchas  
- **Ambiguous success semantics**: The source does not specify how diagnostic success is determined when `RequireAllUnitsPassDiagnostic` is `false`. It is unclear whether success is automatic, or if other conditions (e.g., `AllUnitsPassedDiagnostic == true`) still apply.  
- **No validation in `Reset()`**: The method does not validate or guard against invalid states (e.g., resetting mid-diagnostic), potentially leading to inconsistent behavior if called at inappropriate times.  
- **No thread-safety**: The class is a simple POCO with no synchronization primitives; concurrent use without external locking may cause race conditions.  
- **No documentation on `IStatusParameters` contract**: Since `IStatusParameters` is not included, it is unknown whether `DiagnoseParameters` is expected to implement additional members or adhere to further constraints.  
- **Default behavior may be surprising**: `ProceedToRealtimeWhenDone` defaults to `true`, meaning the system *will* proceed to real-time mode unless explicitly configured otherwise—even if diagnostics fail—unless downstream logic overrides this.
