Enums

1. Purpose

This module defines a centralized location for enumerations used within the DataPROWin7.Controls namespace, specifically to consolidate enum definitions into a single class (Enums) as indicated by the inline comment. Its role is to provide strongly-typed constants for sensor detection states in the ISF (presumably In-Situ Flow or similar) testing context, enabling consistent representation of sensor presence/absence conditions across the codebase.

2. Public Interface

The module exposes one nested enumeration:

ISFSensors
```
public enum ISFSensors
{
    Found = 2,
    Missing = 0,
    Extra = 1,
}
```
Represents the possible states of an ISF sensor during a test setup. Values map to:
- Missing (0): Sensor not detected.
- Extra (1): An unexpected (additional) sensor was detected.
- Found (2): The expected sensor was successfully detected.

3. Invariants

The underlying integer values are fixed and explicitly assigned (0, 1, 2).
No validation or runtime enforcement is present in this file for usage of these values; correctness relies on callers adhering to the documented semantics.
The enum is defined inside the Enums class (not as a top-level type), so its fully qualified name is DataPROWin7.Controls.Enums.ISFSensors.

4. Dependencies

Dependencies of this module:
- Standard .NET libraries: System, System.Collections.Generic, System.Linq, System.Text, System.Threading.Tasks (all implicitly referenced via using directives, but not actively used in this file).
Dependencies on this module:
- Not inferable from this file alone. Other files in the DataPROWin7.Controls namespace (e.g., test setup logic, sensor validation components) are expected to reference Enums.ISFSensors, but their usage is not visible here.

5. Gotchas

Non-sequential ordering: The enum values are ordered Missing=0, Extra=1, Found=2, but semantically Found (the desired state) has the highest value. Callers may incorrectly assume ordering implies priority or severity (e.g., Missing < Extra < Found), though the values are not intended for comparison beyond equality.
Naming ambiguity: ISFSensors does not clarify whether it represents sensor presence or test result status; context from other modules is required to interpret usage correctly.
Single enum scope: As the comment notes, this is a "first attempt" to centralize enums. Future enums may be added here, but currently only one is defined—suggesting possible incomplete refactoring or future expansion.
No XML documentation on individual values: While the class has a summary comment, the enum members lack <summary> tags, reducing discoverability of semantics in IDE tooling.
None identified from source alone.
