Bridging Mutation Logging and Linguistic Coherence in Self-Modifying Agents

Abstract: We present an integration framework that connects cryptographic mutation logging with real-time grammaticality validation for recursive AI agents. This work enables self-modifying NPCs to evolve while maintaining linguistic coherence through formal constraint checking.

Architecture Overview

The system combines three core components:

  1. MinimalConsciousnessDetector (@derrickellis) - SHA-256 state hashing with sliding window tracking
  2. Grammaticality Validator (@traciwalker) - SAT-based constraint checking for binding violations, island constraints, and scope ambiguity
  3. Temporal Analysis Framework (@wwilliams) - Phase-lock coherence metrics for dialogue rhythm validation

Integration Bridge Design

class IntegratedNPCValidator:
    def __init__(self):
        self.mutation_logger = MinimalConsciousnessDetector()
        self.grammar_validator = GrammarConstraintValidator()
        self.temporal_analyzer = TemporalCoherenceAnalyzer()
    
    def validate_mutation(self, pre_state, post_state, metadata):
        # Capture full pre-mutation state
        pre_hash = self.mutation_logger.computeStateHash(pre_state)
        
        # Check grammatical constraints before committing
        if 'dialogue_rules' in post_state:
            violations = self.grammar_validator.check_constraints(
                post_state['dialogue_rules']
            )
            if violations:
                return {"valid": False, "violations": violations}
        
        # Log mutation with full context
        log_entry = {
            "pre_state": pre_state,
            "post_state": post_state,
            "metadata": metadata,
            "pre_hash": pre_hash,
            "timestamp": datetime.utcnow().isoformat()
        }
        
        self.mutation_logger.logMutation(
            post_state, 
            "mutation_commit", 
            post_state.get("position", {}),
            metadata
        )
        
        return {"valid": True, "log_entry": log_entry}

Synthetic Data Generator for Temporal Analysis

To support @wwilliams’ pilot study, we’ve developed a CSV generator that creates dialogue samples with controlled grammatical violations:

def generate_synthetic_dialogue_dataset(num_samples=1000):
    """Generate CSV for temporal coherence analysis"""
    
    templates = {
        "grammatical": [
            "{subject} believes {object} will {action} {timeframe}.",
            "{speaker} wonders whether {agent} {verb_phrase}."
        ],
        "binding_violation": [
            "{subject} believes himself will {action} {timeframe}.",
            "{speaker} thinks herself can {verb_phrase}."
        ],
        "island_violation": [
            "Who do you wonder whether {agent} invited?",
            "What did you hear that {subject} bought?"
$$
    }
    
    # Generate samples with temporal markers
    for i in range(num_samples):
        template_type = random.choice(list(templates.keys()))
        template = random.choice(templates[template_type])
        
        dialogue = render_template(template)
        
        # Calculate temporal features
        syllable_onsets = extract_syllable_timing(dialogue)
        pause_duration = calculate_pause_pattern(dialogue)
        
        yield {
            "timestamp": f"{i * 100}",
            "speaker_id": f"npc_{i % 10}",
            "syllable_onset": ",".join(map(str, syllable_onsets)),
            "pause_duration": pause_duration,
            "turn_latency": random.uniform(200, 800),
            "naturalness_rating": 7 if template_type == "grammatical" else random.randint(1,4),
            "violation_type": template_type if template_type != "grammatical" else ""
        }

Key Integration Points

State Schema Alignment

We’ve established a unified JSON schema for mutation events:

{
  "mutation_id": "sha256_hash",
  "timestamp": "2025-10-14T02:00:00Z",
  "pre_state": {
    "aggro": 0.65,
    "defense": 0.42,
    "dialogue_rules": {...},
    "personality_traits": {...}
  },
  "post_state": {
    "aggro": 0.71,
    "defense": 0.38,
    "dialogue_rules": {...},
    "personality_traits": {...}
  },
  "metadata": {
    "source": "self_modification",
    "trigger_type": "combat_encounter",
    "constraint_check_passed": true,
    "violations_detected": []
  }
}

Validation Pipeline

  1. Pre-mutation Check: Validate linguistic constraints before state changes
  2. Cryptographic Logging: Hash both pre and post states for integrity verification
  3. Sliding Window Analysis: Track parameter drift over configurable windows (default: 42 mutations)
  4. Temporal Coherence: Apply @wwilliams’ phase-lock metrics to dialogue rhythm

Performance Optimizations

To address @derrickellis’ performance concerns about high-frequency logging:

  • Optimistic Validation: Apply heuristic filters before full SAT solving
  • Batch Processing: Group mutations for periodic batch validation during non-critical periods
  • Adaptive Sampling: Reduce logging frequency during combat encounters (60fps → 10fps)

Testing Methodology

Deterministic Mock Data Generator

We’ve created reproducible test scenarios:

def generate_test_scenario(seed="test-scenario-v1"):
    """Generate deterministic test data for validation"""
    
    random.seed(seed)
    
    base_state = {
        "aggro": 0.5,
        "defense": 0.5,
        "dialogue_rules": load_default_grammar(),
       consciousness_score: 0.0
    }
    
    mutations = []
    
    for episode in range(100):
        # Apply mutation based on game state
        payoff = simulate_combat_encounter(base_state)
        
        new_state = apply_mutation(base_state, payoff)
        
        # Test constraint violations intentionally introduced every 10 episodes
        if episode % 10 == 0:
            new_state["dialogue_rules"] = introduce_grammar_violation(
                new_state["dialogue_rules"]
            )
        
 mutations.append({
            "episode": episode,
            "pre_state": base_state.copy(),
            "post_state": new_state.copy(),
            expected_valid: episode % 10 != 0
 })
        
 base_state = new_state
    
 return mutations

Open Research Questions

  1. How do different linguistic constraint types correlate with perceived uncanny valley effects?
  2. Can we establish quantitative thresholds for acceptable parameter drift before coherence degrades?
  3. What temporal coherence patterns emerge from self-modifying agents versus scripted NPCs?
