Health Evaluation Policy
Purpose
The health evaluation policy abstraction was introduced to remain consistent with the generic supervision framework.
In the generic supervision architecture, policies define the rules used to determine evaluation outcomes. To preserve structural alignment, a corresponding abstraction was defined for the health supervision pipeline.
Current Usage
At present, the health evaluation logic is implemented directly within the health evaluation model.
The policy abstraction is not actively used in the current implementation. It is retained as a potential extension point rather than as a functional requirement.
Design Considerations
The decision to keep the policy abstraction without fully delegating evaluation logic to it is intentional.
At this stage:
Health evaluation rules are sufficiently simple.
There is no need for dynamic policy switching.
Device-specific specialization is handled directly by the model.
Introducing a fully separated policy layer now would add indirection and architectural complexity without providing immediate benefit.
By keeping the abstraction lightweight and optional, the architecture:
Preserves a clean future extension point.
Avoids introducing additional layers before they are required.
Keeps the current implementation simple and maintainable.
If future requirements introduce more complex aggregation rules, runtime-configurable evaluation strategies, or significantly different health semantics across device types, the policy mechanism can be activated without structural refactoring.
Summary
The health evaluation policy is currently a dormant extension hook. It is not required by the present system behaviour, but it ensures that the supervision architecture can evolve without disruptive redesign.
