Structural Rewilding: Homotopical Artificial Life

"Life is not just the state of the system, but the topology of the changes (diffs) it can undergo." — zubyul synthesis

Overview

Structural Rewilding applies homotopy type theory to Artificial Life, treating organisms as morphisms between states rather than states themselves. The key insight: verification happens at interaction time via Narya bridge types, not static self-verification.

Interaction Time Verification

Unlike static type checking, verification occurs during interaction:

-- The bridge is constructed at interaction time
def verify_rewilding 
  (Old New : World) 
  (structural_change : Diff World Old New)
  (behavior : Old → Action) 
  : Bridge (behavior Old) (behavior New) := 
    construct_at_runtime structural_change behavior

Key Properties:

• Bridge types are computational proofs
• Verification is lazy (constructed when needed)
• Failure = type error at interaction boundary

A-Life Model Analysis

1. Continuous Substrate: Neural Cellular Automata & Lenia

Models: H-Lenia, Neural Particle Automata, Flow-Lenia

class HLeniaBridge:
    """Bridge type for H-Lenia structural changes."""
    
    def verify(self, layer1_state, layer2_state):
        # Bridge validates energy coherence
        energy_l1 = self.compute_energy(layer1_state)
        energy_l2 = self.compute_energy(layer2_state)
        
        # Coherence: energy flow must be consistent
        return abs(energy_l1 - energy_l2) < self.epsilon
    
    def rewild(self, state, new_layer):
        """Add layer only if bridge validates."""
        bridge = self.construct_bridge(state, new_layer)
        if not bridge.is_valid():
            raise BridgeError("Structural change breaks soliton stability")
        return state.with_layer(new_layer)

Rewilding Effect: System grows new spatial dimensions/resolutions on-the-fly without breaking organism persistence.

2. Semantic Substrate: LLM Societies & Language Agents

Models: Society of Mind on ALTER3, Internalist Cultural Evolution

class SemanticBridge:
    """Bridge for LLM module rewilding."""
    
    def verify_module_addition(self, agent, new_module):
        # Get agent's identity invariant
        identity = agent.extract_identity()
        
        # Simulate with new module
        test_messages = agent.generate_with(new_module)
        
        # Bridge validates identity preservation
        return all(
            self.maintains_identity(msg, identity) 
            for msg in test_messages
        )

Rewilding Effect: Society of Mind becomes fluid. K-lines form/dissolve dynamically, validated by coherence with agent identity.

3. Logical/Discrete Substrate: Digital Circuits & Rule Evolution

Models: Self-Organizing Digital Circuits, QD-LEAR

class CircuitBridge:
    """Bridge for circuit topology rewilding."""
    
    def verify_rewiring(self, old_circuit, new_circuit, test_inputs):
        # Structure can drift wildly...
        # ...as long as function remains pinned
        for inp in test_inputs:
            old_out = old_circuit(inp)
            new_out = new_circuit(inp)
            if old_out != new_out:
                return False
        return True
    
    def rewild(self, circuit, damage_location):
        """Reroute around damage while preserving function."""
        candidate = circuit.propose_rewiring(damage_location)
        bridge = self.verify_rewiring(circuit, candidate, self.test_suite)
        if not bridge:
            raise BridgeError("Rewiring changes circuit function")
        return candidate

Rewilding Effect: Circuit becomes "liquid" - constantly rewriting topology for optimization without halting execution.

Scale MG Standard: Transitivity and Coherence

In a Skills Dynamic Graph (G), every capability is a node. Structural rewilding = adding/removing nodes and edges.

The Transitivity Property

If Skill A → Skill B and we add Skill C bridging them:

    A ──────→ B
     ╲       ↗
      ╲     ╱
       ╲   ╱
        ↘ ↙
         C

We need a 2-cell (surface) filling the triangle.

In Narya Terms:

def transitivity_bridge
  (A B C : Skill)
  (ab : A → B)
  (ac : A → C)
  (cb : C → B)
  : Bridge ab (ac >> cb) := 
    -- Constructed at interaction time
    interaction_verify ac cb

Coherence on the Way In

Using Narya, we don't just "add" a skill. We define a Diff between world models:

-- Step 1: Define the Diff
def add_skill : Diff World Old New := ...

-- Step 2: Construct the Bridge
-- Must show how every neighbor adapts
def bridge : Bridge Old.behaviors New.behaviors := 
  -- Example: Tool Use added to Foraging agent
  -- Bridge maps Forage(EmptyHand) → Forage(Tool)
  fun old_behavior => 
    match old_behavior with
    | Forage(EmptyHand) => Forage(Tool)
    | other => other

-- Step 3: Verification
-- If agent cannot instantiate bridge, skill not admitted

Result: World Model remains a continuous manifold of behavior, not a fractured set of disconnected scripts.
