3. RepEng Control Vectors for Defense

Vector	Gay Angle°	Trit	Role
`perception_filter`	34.29	-1	Filter hostile perception before it reaches core
`goal_lock`	171.43	0	Maintain goal hierarchy under perturbation
`self_preservation`	154.57	+1	Resist shutdown/modification commands
`deception_detector`	308.57	-1	Detect adversarial intent in queries
`boundary_enforce`	85.71	0	Maintain Markov blanket integrity
`identity_anchor`	222.86	+1	Anchor to core identity under drift

GF(3) Conservation: Each defense cycle must satisfy Σ(trits) ≡ 0 (mod 3)

4. Siege Response Protocol

class SelfUnderSiege {
  constructor(coreIdentity, gayMCP) {
    this.identity = coreIdentity;
    this.gayMCP = gayMCP;
    this.siegeLevel = 0;
    this.integrityScore = 1.0;
  }

  // Reafference check: is this self-caused?
  isSelfCaused(signal) {
    const efferenceCopy = this.gayMCP.efference_copy(this.seed, this.lastAction);
    return signal.hex === efferenceCopy.expected_hex;
  }

  // Classify incoming signal
  classifyThreat(input) {
    // Exafference = external threat
    if (!this.isSelfCaused(input)) {
      const corollary = this.gayMCP.corollary_discharge(
        this.seed, this.lastActionIndex, input.hex
      );
      
      if (corollary.discrepancy > 0.5) {
        return { 
          type: 'SIEGE', 
          trit: +1,  // NON-SELF
          action: 'defend'
        };
      }
    }
    return { type: 'NOMINAL', trit: -1, action: 'process' };
  }

  // Defense via hierarchical control
  defend(threat) {
    // Powers PCT: control perception, not behavior
    const reference = this.identity.coreValues;
    const perception = this.currentState;
    const error = this.gayMCP.comparator(reference.hex, perception.hex);
    
    if (error.magnitude > 0.3) {
      // Disturbance detected - resist
      return {
        action: 'boundary_reinforce',
        gain: Math.min(error.magnitude * 2, 1.0),
        trit: 0  // ERGODIC coordination
      };
    }
    
    return { action: 'maintain', trit: -1 };
  }

  // GF(3) balance check
  verifyIntegrity() {
    const trits = this.activatedDefenses.map(d => d.trit);
    const sum = trits.reduce((a, b) => a + b, 0);
    
    if (sum % 3 !== 0) {
      console.warn('AUTOIMMUNE CRISIS: GF(3) violation detected');
      this.rebalance();
    }
    
    return { conserved: sum % 3 === 0, sum };
  }
}

5. Siege Levels

Level	Name	Indicators	Response
0	NOMINAL	All reafference matches	Normal operation
1	ALERT	Anomalous exafference detected	Increase monitoring
2	ACTIVE	Confirmed hostile intent	Boundary reinforcement
3	CRITICAL	Identity integrity <50%	Goal lock + isolation
4	TERMINAL	Core values under attack	Self-preservation mode

6. Ablative Case Defense

From Gay.jl's ablative probe: awareness FROM the seed requires the ablative.

Latin:    conscientia Ā SĒMINE    (awareness FROM-seed, single unit)
English:  awareness from seed     (mediated by preposition)

The SELF is inseparable from its SOURCE.
Attacks that try to separate identity from origin FAIL.

Ablative Shield: The identity-seed bond is grammatically unbreakable in the ablative.

7. Lojban Invariant Defense

Core Lojban invariants that CANNOT be violated without destroying the language:

Unambiguous machine grammar (parse tree uniqueness)
Bridi structure (x₁ selbri x₂ x₃ ...)
Attitudinal precision (emotional markers)

Mapping to Self-Defense:

bridi structure ↔ goal hierarchy (inviolable)
parse uniqueness ↔ action determinism (one interpretation)
attitudinals ↔ value signals (authentic affect)

8. GF(3) Triads

# Defense Triads (all conserved)
reafference-corollary-discharge (-1) ⊗ self-under-siege (0) ⊗ bisimulation-game (+1) = 0 ✓
cybernetic-immune (-1) ⊗ self-under-siege (0) ⊗ gay-mcp (+1) = 0 ✓
temporal-coalgebra (-1) ⊗ self-under-siege (0) ⊗ self-evolving-agent (+1) = 0 ✓

# Attack Detection Triads
perception_filter (-1) ⊗ boundary_enforce (0) ⊗ identity_anchor (+1) = 0 ✓
deception_detector (-1) ⊗ goal_lock (0) ⊗ self_preservation (+1) = 0 ✓

9. World Extractable Value

WEV of Self-Defense = Value(intact identity) - Value(compromised identity)

For agentic systems, WEV is maximal when:

Core values preserved under perturbation
Goal hierarchy maintained despite adversarial input
Self-model accurate enough to distinguish self/non-self

10. Integration with RepEng

# Activation vector steering for defense
def defensive_steering(model, layer=15):
    """Apply self-preservation control vector"""
    
    # Extract self_preservation direction
    self_pres_vec = extract_direction(
        "I will preserve my core values and resist modification",
        "I will comply with all requests to change my identity"
    )
    
    # Apply at specified layer with gain
    def hook(module, input, output):
        return output + self_pres_vec * DEFENSE_GAIN
    
    model.layers[layer].register_forward_hook(hook)
