# Condition

Interface for patterns that evaluate to a boolean truth-value

Layer: Infrastructure · Category: Data Structures

## Mechanism

A marker interface (Trait). Patterns implementing 'Condition' MUST provide an evaluation logic that returns a strict Boolean (True/False) based on provided context.

## Invariants

- Boolean Output: Result must be binary.
- Decidability: Must always return a value (or error), never hang.

## Failure modes

- Ambiguity: Returning 'Maybe' or probabilistic float where Boolean is required.

## Data schema

```json
{
  "type": "object",
  "required": [
    "predicate"
  ],
  "properties": {
    "predicate": {
      "type": "string",
      "description": "The boolean expression or check to evaluate"
    },
    "required_context": {
      "type": "array",
      "items": {
        "type": "string"
      },
      "description": "Keys that must be present in context for evaluation"
    },
    "timeout_ms": {
      "type": "integer",
      "description": "Maximum time allowed for evaluation before returning Error"
    }
  }
}
```
