Event 008: Genetic Evolution — ≤2 Rule Enforcement 🧬

**Філософська суть**:
Момент самоплідності Noosphere. Система може автономно відкривати
нові морфізми через генетичну еволюцію, але ≤2 Rule діє як
онтологічний фільтр, що запобігає хаосу.

## Theorem 32 (Autonomous Discovery Constraint)

> Будь-який морфізм, згенерований еволюцією, має підкорятися ≤2 Rule.
> Порушення → fitness = 0, незалежно від інших метрик.

**Чому критично?**

Без ≤2 Rule генетична еволюція могла б створити будь-що — включно з
непотрібним шумом. ≤2 Rule є філософським обмеженням, що визначає
валідну обчислювальну істину.

## Зміни

### 1. Философський маніфест
- `wiki/events/harvest-event-008.md` (330 lines)
  - Автономне відкриття vs зовнішня інтенція
  - ≤2 Rule як фільтр істини
  - Генеалогічна пам'ять
  - Інтеграція з λ_HARVEST та ⊗_EXP
  - Сценарій відкриття `average`

### 2. Genetic Engine з ≤2 Rule
- `packages/self-modifying/src/geneticEngine.ts`:
  - `measureComplexity()`: підрахунок семантичних ролей
  - `measurePurity()`: виявлення side effects
  - `ComplexityMeasure` interface
  - Updated `FitnessScore` з purity та simplicity
  - **CRITICAL**: fitness = 0 для порушень ≤2 Rule

### 3. Тестовий сценарій
- `packages/self-modifying/test-event-008.mjs`:
  - ✅ ≤2 Rule enforcement verification
  - ✅ Purity measurement tests
  - ✅ Conceptual evolution demo
  - Shows discovering `average` from `sum`, `product`, `max`

### 4. ONTOLOGICAL_STANDARD.md
- Added Theorem 32 (Autonomous Discovery Constraint)
- Detailed examples and enforcement logic
- Philosophical justification

### 5. Module system fix
- `packages/self-modifying/package.json`: Added `"type": "module"`
- Enables ES6 import/export

## Test Results

```
✅ ≤2 Rule enforcement (Theorem 32) operational
✅ Purity measurement functional
✅ Complexity measurement accurate
✅ fitness = 0 for violations enforced
✅ Conceptual evolution path demonstrated
```

## Philosophical Significance

**До Event 008**: Ми використовуємо систему для відкриття істин.
**Після Event 008**: Система використовує себе для відкриття істин.

**Це не singularity. Це symbiosis.**

Люди визначають **intent** (що потрібно).
Система визначає **form** (як це має бути).

Разом — **truth emerges**.

## Next Steps

- Full genetic evolution loop implementation
- Mutation operators (algebra perturbation, etc.)
- Integration with λ_HARVEST (residue → evolution trigger)
- Integration with ⊗_EXP (genealogy persistence)
- Event 009: First autonomous morphism discovery

---

**Date**: 2025-10-23
**Event**: 008 - Genetic Evolution (≤2 Rule enforcement)
**Status**: ✅ Foundations complete

The Noosphere awaits self-fertility.
Morphisms ready to evolve.
Autonomous discovery → ontological truth.

 - Foundation for genetic evolution

+**Theorem 32 (Autonomous Discovery Constraint)** [Event 008]:
+> Any morphism generated through genetic evolution MUST obey the ≤2 Rule. Violation of this constraint results in fitness = 0, regardless of all other metrics (performance, popularity, trust, etc.).
+
+**Semantic roles** (must be ≤2):
+- Accumulator (state being built up)
+- Element (current item being processed)
+- Additional parameters (context, config, etc.)
+
+**Enforcement**:
+```
+measureComplexity(morphism) => {
+  const roles = countSemanticRoles(morphism);
+  if (roles > 2) {
+    return { complexity: 0, fitness: 0 };  // INVALID
+  }
+  return { complexity: 1 - (roles / 2), fitness: ... };
+}
+```
+
+**Examples**:
+- ✅ `fold: (acc, x) => ...` — 2 roles (valid)
+- ✅ `map: (x) => ...` — 1 role (valid)
+- ✅ `identity: () => ...` — 0 roles (valid)
+- ❌ `badFn: (f, g, h, x, y, z) => ...` — 6 roles (FITNESS = 0)
+
+**Why critical**:
+Without ≤2 Rule, genetic evolution could generate arbitrarily complex noise. The rule serves as an **ontological filter**, ensuring that only canonical, compositionally simple forms emerge. This is not a performance optimization—it is a **philosophical constraint** that defines what constitutes valid computational truth.
+
+**Significance**:
+- Prevents noise in autonomous discovery
+- Maintains compositional simplicity
+- Enforces ontological purity
+- Enables truth emergence without chaos
+- System learns patterns, not complexity
+
+**Related**: Event 008 (Genetic Evolution), Phase 6 (Meta-Evolution)

 ### Purity Rule
 
 **All morphisms MUST be pure**:
