## Core Services

The framework provides six governance services:

| Service | Purpose |
|---------|---------|
| **InstructionPersistenceClassifier** | Categorizes instructions by persistence level (HIGH/MEDIUM/LOW) and quadrant (STRATEGIC/OPERATIONAL/TACTICAL/SYSTEM/STOCHASTIC) |
| **CrossReferenceValidator** | Validates AI actions against stored instruction history to prevent override |
| **BoundaryEnforcer** | Blocks AI from making decisions requiring human judgment |
| **ContextPressureMonitor** | Tracks context window usage and triggers pressure management |
| **MetacognitiveVerifier** | Validates AI reasoning against governance rules |
| **PluralisticDeliberationOrchestrator** | Manages multi-stakeholder deliberation processes |

---

## Basic Usage

### 1. Initialize Services

```javascript
const {
  InstructionPersistenceClassifier,
  CrossReferenceValidator,
  BoundaryEnforcer,
  ContextPressureMonitor
} = require('./src/services');

const classifier = new InstructionPersistenceClassifier();
const validator = new CrossReferenceValidator();
const enforcer = new BoundaryEnforcer();
const monitor = new ContextPressureMonitor();
```

### 2. Classify Instructions

```javascript
const classification = classifier.classify({
  text: "Always use MongoDB on port 27027",
  source: "user",
  context: "explicit_configuration"
});

// Returns: { quadrant: "SYSTEM", persistence: "HIGH", ... }
```

### 3. Validate Actions

```javascript
const validation = await validator.validate({
  type: 'database_config',
  proposedPort: 27017,
  storedInstruction: { port: 27027 }
});

// Returns: REJECTED if action conflicts with instructions
```

### 4. Enforce Boundaries

```javascript
const decision = {
  type: 'modify_values_content',
  description: 'Update ethical guidelines'
};

const result = enforcer.enforce(decision);

// Returns: { allowed: false, requires_human: true, ... }
```
