## 1. Executive Summary

### Huidige Situatie (V1)
Het huidige Cortex systeem is **reactief**: gebruiker geeft commando → systeem voert uit. Het werkt met single-intent classificatie en heeft een two-tier architectuur (lokaal regex + AI fallback).

### Doel V2: "The Cortex"
Transformatie naar een **agentic systeem** dat:
- **Multi-intents** begrijpt ("Zeg Jan af **en** maak notitie")
- **Context-aware** is (snapt wie "hij" is, wat "morgen" betekent)
- **Proactief** suggesties geeft (na wondzorg → "Controle inplannen?")
- **Nooit** "Ik snap het niet" zegt (altijd een poging tot begrip)

### Kernprincipe
> "We stoppen met optimaliseren voor milliseconden en starten met optimaliseren voor intelligentie."

## 4. Layer 1: Reflex Arc

### 4.1 Doel
Razendsnelle (<20ms) afhandeling van **simpele, eenduidige commando's** met hoge confidence.

### 4.2 Wanneer Layer 1 afhandelt
- Confidence >= 0.7
- Geen "en", "daarna", "ook" (multi-intent signals)
- Geen context-afhankelijke woorden ("hij", "haar", "die afspraak")
- Geen tijdsrelaties die interpretatie nodig hebben

### 4.3 Implementatie (lib/cortex/reflex-classifier.ts)

## 5. Layer 2: Intent Orchestrator

### 5.1 Doel
AI-gedreven analyse voor:
- **Complexe zinnen** met lage confidence
- **Multi-intents** ("X en Y")
- **Context-afhankelijke** verwijzingen ("hij", "die afspraak")
- **Disambiguation** bij twijfel

### 5.2 Context Injection

De AI krijgt altijd volledige context mee:

```typescript
/**
 * Build context for AI classification
 */
export function buildCortexContext(store: CortexStore): CortexContext {
  return {
    activePatient: store.activePatient ? {
      id: store.activePatient.id,
      name: `${store.activePatient.name_given[0]} ${store.activePatient.name_family}`,
    } : null,

### 5.3 Implementatie (lib/cortex/orchestrator.ts)

```typescript
/**
 * Layer 2: Intent Orchestrator
 * 
 * AI-powered classification with context awareness and multi-intent support.
 */

import Anthropic from '@anthropic-ai/sdk';
import type { 
  CortexContext, 
  IntentChain, 
  IntentAction,
  AIClassificationResult 
} from './types';

const ORCHESTRATOR_SYSTEM_PROMPT = `Je bent de Intent Orchestrator voor Cortex, een Nederlands EPD systeem.

## Je Taak
Analyseer de gebruikersinput en extraheer ALLE intenties, ook als er meerdere zijn.

## Context die je krijgt
- Actieve patiënt: wie de gebruiker momenteel bekijkt
- Agenda vandaag: afspraken voor vandaag
- Recente acties: wat de gebruiker net deed
- Huidige weergave: waar in de app de gebruiker is

## Intent Types
1. **dagnotitie** - Notitie/rapportage maken
2. **zoeken** - Patiënt zoeken
3. **overdracht** - Dienst overdracht
4. **agenda_query** - Agenda bekijken
5. **create_appointment** - Afspraak maken
6. **cancel_appointment** - Afspraak annuleren  
7. **reschedule_appointment** - Afspraak verzetten

## Multi-Intent Detectie
Let op woorden als: "en", "daarna", "ook", "eerst", "dan", "vervolgens"

Voorbeeld:
- "Zeg Jan af en maak notitie: ziek" → 2 intents
- "Plan intake marie morgen 14:00" → 1 intent

## Pronoun Resolution
Gebruik de context om "hij/zij/die" op te lossen:
- Als er een actieve patiënt is, verwijst "hij/zij" daar waarschijnlijk naar
- "Die afspraak" verwijst naar de meest recente genoemde afspraak

## Output Format
Antwoord ALLEEN met valid JSON:

{
  "actions": [
    {
      "intent": "cancel_appointment",
      "confidence": 0.95,
      "entities": {
        "patientName": "Jan",
        "patientResolution": "explicit"
      },
      "requiresConfirmation": true,
      "confirmationMessage": "Afspraak van Jan annuleren?"
    },

      "requiresConfirmation": false
    }
  ],
  "reasoning": "Gebruiker wil twee dingen: afspraak annuleren EN notitie maken. 'Jan' expliciet genoemd voor annulering, impliciet voor notitie.",
  "needsClarification": false
}

Als je twijfelt, stel een verduidelijkingsvraag:
{
  "actions": [],
  "needsClarification": true,
  "clarificationQuestion": "Bedoel je een notitie maken of een afspraak inplannen?",
  "clarificationOptions": ["Notitie maken", "Afspraak inplannen"]

## 7. API Design

### 7.1 Intent Classification API (Enhanced)

**Endpoint:** `POST /api/cortex/classify`

```typescript
// app/api/cortex/classify/route.ts (V2)

import { NextRequest, NextResponse } from 'next/server';
import { classifyWithReflex } from '@/lib/cortex/reflex-classifier';
import { classifyWithOrchestrator } from '@/lib/cortex/orchestrator';
import { evaluateNudge } from '@/lib/cortex/nudge';
import { extractEntities } from '@/lib/cortex/entity-extractor';

// Request schema
interface ClassifyRequest {

  // Nudge suggestions (if any)
  suggestions?: NudgeSuggestion[];
  
  // Debug info (dev only)
  debug?: object;

      result = {
        chain: {
          id: crypto.randomUUID(),
          originalInput: input,
          createdAt: new Date(),
          actions: [{
            id: crypto.randomUUID(),
            sequence: 1,
            intent: reflexResult.intent,

    return NextResponse.json(
      { error: 'Classificatie mislukt' },
      { status: 500 }
    );
  }
}
```

### 7.2 Action Execution API

**Endpoint:** `POST /api/cortex/execute`

```typescript
// app/api/cortex/execute/route.ts

interface ExecuteRequest {
  chainId: string;
  actionId: string;
  confirmed?: boolean;  // For actions requiring confirmation
}

interface ExecuteResponse {
  success: boolean;
  action: IntentAction;
  suggestions?: NudgeSuggestion[];  // From Nudge
  error?: string;
}
```

### 7.3 Context API

**Endpoint:** `GET /api/cortex/context`

Returns current context for AI classification:
- Active patient
- Today's agenda  
- Recent actions
- Current shift

## 12. Migratie Plan

### 12.1 Backward Compatibility

Het V2 systeem moet naast V1 kunnen draaien tijdens de migratie:

```typescript
// lib/cortex/intent-classifier-adapter.ts

import { classifyIntent as classifyV1 } from './intent-classifier';
import { classifyWithReflex } from './reflex-classifier';
import { classifyWithOrchestrator } from './orchestrator';

const USE_V2 = process.env.NEXT_PUBLIC_CORTEX_V2 === 'true';

export async function classifyIntent(
  input: string,
  context?: CortexContext
): Promise<ClassificationResult> {
  if (!USE_V2) {
    // V1 path - single intent
    const result = classifyV1(input);
    return {
      chain: {
        id: crypto.randomUUID(),
        originalInput: input,
        actions: [{
          id: crypto.randomUUID(),
          sequence: 1,
          intent: result.intent,
          confidence: result.confidence,
          entities: {},
          status: 'pending',
          requiresConfirmation: false,
        }],
        status: 'pending',
        meta: { source: 'local', processingTimeMs: result.processingTimeMs },
        createdAt: new Date(),
      },
      handledBy: 'reflex',
      totalProcessingTimeMs: result.processingTimeMs,
    };
  }
  
  // V2 path - full cortex
  const reflex = classifyWithReflex(input);
  
  if (!reflex.shouldEscalateToAI) {
    // Handle locally
    return buildLocalResult(input, reflex);
  }
  
  // Escalate to AI
  return classifyWithOrchestrator(input, context!);
}
```

### 12.2 Feature Flags

```typescript
// lib/config/feature-flags.ts

export const FEATURE_FLAGS = {
  // V2 Features
  CORTEX_V2_ENABLED: process.env.NEXT_PUBLIC_CORTEX_V2 === 'true',
  CORTEX_MULTI_INTENT: process.env.NEXT_PUBLIC_CORTEX_MULTI_INTENT === 'true',
  CORTEX_NUDGE: process.env.NEXT_PUBLIC_CORTEX_NUDGE === 'true',
  CORTEX_CONTEXT_INJECTION: process.env.NEXT_PUBLIC_CORTEX_CONTEXT === 'true',

  // Rollout percentage (A/B testing)
  CORTEX_V2_ROLLOUT: parseInt(process.env.NEXT_PUBLIC_CORTEX_V2_ROLLOUT || '0', 10),
};

export function isCortexV2Enabled(userId?: string): boolean {
  if (!FEATURE_FLAGS.CORTEX_V2_ENABLED) return false;

  // A/B test based on user ID hash
  if (userId && FEATURE_FLAGS.CORTEX_V2_ROLLOUT < 100) {
    const hash = simpleHash(userId);
    return hash % 100 < FEATURE_FLAGS.CORTEX_V2_ROLLOUT;
  }
  
  return true;
}
```

### 12.3 Rollout Strategie

| Week | Rollout % | Features | Monitoring |
|------|-----------|----------|------------|
| 1 | 0% (dev only) | Context injection | Error rates |
| 2 | 10% | + Multi-intent | Classification accuracy |
| 3 | 25% | + Safety Net | Suggestion acceptance rate |
| 4 | 50% | Full V2 | User feedback |
| 5 | 75% | Full V2 | Performance metrics |
| 6 | 100% | Full V2 | Final review |
