# SliceSimpleArm

### 1. Purpose  
This module defines the command and response enumerations used for communication with a SliceSimpleArm (SSA) subsystem—likely a hardware control or embedded device interface. `SSACommand` enumerates the set of high-level operations that can be issued to the device (e.g., arming, starting recording, diagnostics), while `SSAResponse` enumerates the possible structured responses the system may return, including success/failure states and specific error conditions (e.g., `NoSensorsFound`, `DiagnosticsFailedOffsetTolerance`). These enums serve as the contract for command–response semantics between the host software and the SSA hardware or its simulator.

### 2. Public Interface  
The module exposes two public enums:

- **`SSACommand`**  
  *Type:* `enum`  
  *Values:*  
  - `ConfigureDevice` – Likely used to initialize or reconfigure device parameters.  
  - `Diagnostics` – Triggers a self-test or health check.  
  - `Arm` – Arms the device for operation (e.g., enables data acquisition or triggering).  
  - `StartRecord` – Begins data recording.  
  - `CheckForArmed` – Polls the device to verify if it is armed.  
  - `Disarm` – Disarms the device, halting active operations.  
  - `Download` – Requests data or logs from the device.  
  - `SetLowPowerMode` – Puts the device into a low-power state.  
  - `Trigger` – Sends an external trigger command (e.g., manual or timed trigger).  

- **`SSAResponse`**  
  *Type:* `enum`  
  *Values:*  
  - `Unknown` – Default/unrecognized response.  
  - `Status` – Generic status update (possibly informational).  
  - `Pass` – Operation completed successfully.  
  - `Fail` – Operation failed for unspecified reason.  
  - `SystemNotArmed` – Requested operation requires the system to be armed first.  
  - `NoSensorsFound` – No sensors detected during diagnostics or configuration.  
  - `NoEIDsFound` – No EIDs (Event Identifiers?) found—likely during configuration or diagnostics.  
  - `UnknownEIDFound` – An unexpected or invalid EID was encountered.  
  - `NoDASConnected` – Data Acquisition System (DAS) is not connected or detected.  
  - `ExceptionThrown` – An exception occurred during command processing.  
  - `DiagnosticsFailedOffsetTolerance` – Diagnostics failed due to sensor offset exceeding tolerance.  
  - `DiagnosticsFailedShuntCheck` – Diagnostics failed during shunt verification (e.g., electrical integrity test).  

### 3. Invariants  
- The `SSACommand` and `SSAResponse` enums are strictly *declarative*—they define symbolic names only; no validation, serialization, or parsing logic resides in this file.  
- Each `SSACommand` value corresponds to a well-defined operation in the SSA protocol; similarly, each `SSAResponse` value represents a distinct outcome or error condition.  
- No ordering guarantees are implied by the enum values (i.e., they are not ordered by priority, frequency, or sequence).  
- The `Unknown` value in both enums likely serves as a sentinel for uninitialized or unhandled cases.

### 4. Dependencies  
- **Internal dependencies:** This module resides in `DTS.Common.Enums.SliceSimpleArm`, suggesting it is part of a shared/common library (`DTS.CommonCore`). It has no external dependencies beyond the base .NET runtime (no `using` directives beyond `namespace`).  
- **Consumers:** Other modules in the codebase (e.g., communication layers, device drivers, UI logic) likely reference this enum to construct commands and interpret responses. The presence of `DTS.Common` in the namespace implies this is a cross-cutting contract used by higher-level components (e.g., `DTS.CommonCore`, `DTS.SliceSimpleArm`, or test harnesses).  
- **No external libraries or hardware-specific dependencies** are declared in this file.

### 5. Gotchas  
- **Ambiguity in EID/DAS terminology:** The meaning of “EID” (Event Identifier?) and “DAS” (Data Acquisition System?) is not defined in this file. Their usage in `NoEIDsFound`, `UnknownEIDFound`, and `NoDASConnected` suggests domain-specific concepts that require external documentation.  
- **No explicit mapping to command/response payloads:** This file defines *what* commands/responses exist, but not *how* they are serialized, transmitted, or deserialized (e.g., via serial, TCP, or binary protocol). That logic resides elsewhere.  
- **`Status` vs. `Pass`:** The distinction between `Status` (generic update) and `Pass` (explicit success) is unclear—`Status` may be used for intermediate or polling responses, but this is not specified.  
- **No versioning or extensibility guidance:** Adding new commands/responses may break backward compatibility if consumers switch on all values; no attributes or patterns (e.g., `[Flags]`) suggest safe extension strategies.  
- **None identified from source alone.**
