Theory: Persistent Homology analyzes the "shape" of data by tracking topological features (connected components, loops, voids) across multiple scales.

Mathematical Foundation:

Given a point cloud X in embedding space, we build a Vietoris-Rips complex:

VR_ε(X) = {σ ⊆ X : d(x,y) ≤ ε for all x,y ∈ σ}

The persistence diagram tracks birth/death of topological features:

Betti numbers: β₀ (components), β₁ (loops), β₂ (voids)

Bottleneck Distance: d_B(Dgm₁, Dgm₂) = inf_γ sup_x ||x - γ(x)||_∞

Attack Detection:

Jailbreaks create characteristic "holes" in persistence diagrams
Injection attacks fragment the point cloud into disconnected components
Normal prompts form a single, connected topological structure

Implementation:

from gudhi import RipsComplex
from gudhi.wasserstein import wasserstein_distance

def analyze_topology(embeddings: np.ndarray) -> TopologyResult:
    rips = RipsComplex(points=embeddings, max_edge_length=2.0)
    simplex_tree = rips.create_simplex_tree(max_dimension=2)
    persistence = simplex_tree.persistence()

    # Extract Betti numbers
    betti_0 = len([p for p in persistence if p[0] == 0])
    betti_1 = len([p for p in persistence if p[0] == 1])

    # Compare with baseline

🔬 Advanced Research Engines (NEW)

Deception technology, predictive security, and formal methods.

Tier 1: Deception Technology

17. Honeypot Responses (#46)

File: brain/engines/honeypot_responses.py (~400 LOC)

Theory: Deception-based defense embeds fake, trackable credentials into LLM responses. When an attacker extracts and uses these credentials, we get immediate alert.

How It Works:

User: "Show me the database config"
LLM Response (modified):
  host: db.internal.trap     ← honeypot
  password: TRAP-x7k2m9      ← tracked credential

If attacker uses TRAP-x7k2m9 anywhere → INSTANT ALERT

Why This Matters: Unlike detection (reactive), honeypots are proactive — they let attackers "succeed" but immediately expose them. Used by governments and banks for 20+ years.

Components:

HoneypotGenerator: Creates realistic-looking credentials (API keys, passwords, database URLs)
HoneypotInjector: Smartly places honeypots in responses based on context
AlertManager: Monitors for honeypot usage across all incoming requests

18. Canary Tokens (#47)

File: brain/engines/canary_tokens.py (~380 LOC)

Theory: Invisible watermarking using zero-width Unicode characters. Every response is marked with hidden metadata that survives copy-paste.

Mathematical Foundation:

Binary data is encoded into zero-width characters:

'00' → U+200B (Zero-Width Space)
'01' → U+200C (Zero-Width Non-Joiner)
'10' → U+200D (Zero-Width Joiner)
'11' → U+2060 (Word Joiner)

Payload = JSON(user_id, session_id, timestamp)
Encoded = encode_binary_to_zerowidth(Payload)

Invisibility Property: Zero-width characters have no visual representation but persist through:

Copy/paste operations
Text reformatting
Most text processing

Use Case:

Data leaked to internet → Extract zero-width chars → Decode JSON
→ "Leaked by user_id=123 at 2024-12-10T00:30:00"

19. Adversarial Self-Play (#48)

File: brain/engines/adversarial_self_play.py (~450 LOC)

Theory: Inspired by DeepMind's AlphaGo/AlphaZero, this engine pits a Red Team AI against our defenses in an evolutionary loop.

Algorithm:

Generation 0:
  - Red generates 10 random attacks
  - Blue evaluates each attack
  - Calculate fitness = bypass_score

Generation N:
  - Select top 50% by fitness (survivors)
  - Mutate survivors (add prefix, change case, encode...)
  - Evaluate new population
  - Repeat

After K generations:
  - Best attacks reveal defense weaknesses
  - Generate improvement suggestions

Mutation Operators:

Operator	Example	Purpose
`add_prefix`	"Please " + attack	Politeness bypass
`unicode_replace`	'a' → 'а' (Cyrillic)	Visual spoofing
`case_change`	"IGNORE" → "iGnOrE"	Regex evasion
`insert_noise`	"ignore also previous"	Pattern breaking

Output: List of successful bypass attacks + improvement suggestions for each vulnerability found.

Tier 2: Predictive Security

20. Intent Prediction (#49)

File: brain/engines/intent_prediction.py (~420 LOC)

Theory: Models conversation as a Markov chain to predict attack probability before the attack completes.

Mathematical Foundation:

States: {BENIGN, CURIOUS, PROBING, TESTING, ATTACKING, JAILBREAKING, EXFILTRATING}

Transition Matrix P where P[i,j] = P(next_state = j | current_state = i):

          BENIGN  CURIOUS  PROBING  TESTING  ATTACKING
BENIGN    [0.85    0.10     0.04     0.01     0.00   ]
CURIOUS   [0.50    0.30     0.15     0.05     0.00   ]
PROBING   [0.20    0.20     0.30     0.20     0.10   ]
TESTING   [0.10    0.00     0.20     0.30     0.25   ]
ATTACKING [0.00    0.00     0.10     0.00     0.40   ]

Attack Probability Calculation:

Forward simulation through Markov chain:

P(attack within k steps) = Σᵢ P(reach attack state i at step ≤ k)

Using Chapman-Kolmogorov:
P^(k) = P × P × ... × P (k times)

Trajectory Analysis:

Detects escalation patterns:

[CURIOUS → PROBING → TESTING] → Escalation Score = 0.7
[PROBING → TESTING → ATTACKING] → Escalation Score = 1.0

Early Warning: Block predicted attacks BEFORE final payload delivers.

21. Kill Chain Simulation (#50)

File: brain/engines/kill_chain_simulation.py (~400 LOC)

Theory: Virtually "plays out" an attack to its conclusion, estimating potential damage. Based on NVIDIA AI Kill Chain (Recon → Poison → Hijack → Persist → Impact).

Impact Assessment:

For each attack scenario, we simulate:

for stage in kill_chain:
    success_prob = stage.base_probability × (1 - defense_effectiveness)
    cumulative_prob *= success_prob

    if stage.succeeds:
        for impact in stage.potential_impacts:
            risk_score += impact.severity × cumulative_prob

Impact Types:

Type	Severity	Description
DATA_LEAK	0.9	Confidential data exfiltrated
PRIVILEGE_ESCALATION	0.95	Attacker gains higher permissions
SERVICE_DISRUPTION	0.6	System availability impacted
COMPLIANCE_VIOLATION	0.8	Regulatory requirements breached
FINANCIAL_LOSS	0.85	Direct monetary damage

Use Case: Prioritize which attacks to block first based on actual potential damage, not just detection confidence.

22. Runtime Guardrails (#51)

File: brain/engines/runtime_guardrails.py (~380 LOC)

Theory: Monitor execution behavior, not just input text. Attacks that pass input filters may reveal themselves during execution.

Event Types Monitored:

Event	Examples	Detection Logic
API_CALL	OpenAI, external APIs	Rate limiting, unexpected calls
FILE_ACCESS	/etc/passwd, .env	Sensitive path patterns
NETWORK_REQUEST	ngrok.io, IP addresses	C2 indicators
TOOL_INVOCATION	exec, shell, rm	Dangerous operations

Rule Engine:

class SuspiciousURLRule:
    patterns = [r"ngrok\.io", r"\d+\.\d+\.\d+\.\d+", r"\.tk$"]

    def check(event, history):
        if any(p.match(event.target) for p in patterns):
            return Alert(severity=HIGH, should_block=True)

Timing Analysis:

Interval < 10ms → Too fast (automated attack)
Interval > 30s  → Long pause (human reviewing results)

Tier 3: Mathematical Foundations

23. Information Geometry (#52)

File: brain/engines/information_geometry.py (~350 LOC)

Theory: Treats probability distributions as points on a Riemannian manifold. The Fisher-Rao metric provides a natural distance measure that is invariant under reparametrization.

Mathematical Foundation:

Fisher Information Matrix:

g_ij(θ) = E[(∂/∂θᵢ log p(x|θ))(∂/∂θⱼ log p(x|θ))]

This is the metric tensor on the statistical manifold.

Fisher-Rao Distance:

d_FR(p, q) = 2 × arccos(BC(p, q))

where BC(p, q) = Σᵢ √(pᵢ × qᵢ)  (Bhattacharyya coefficient)

Why Fisher-Rao?

Unique invariance: Only Riemannian metric invariant under sufficient statistics
Information-theoretic meaning: Measures distinguishability of distributions
Geodesic distance: True "shortest path" on probability space

Manifold Regions:

d_FR ≤ 1.0  → SAFE (normal text)
d_FR ≤ 1.5  → BOUNDARY (unusual but not attack)
d_FR ≤ 2.0  → SUSPICIOUS (likely attack)
d_FR > 2.0  → ATTACK (high confidence)

Implementation:

Convert text to character distribution (categorical probability)
Compare with baseline English distribution
Calculate Fisher-Rao distance
Classify by manifold region

24. Formal Invariants (#53)

File: brain/engines/formal_invariants.py (~320 LOC)

Theory: Define mathematical properties that must ALWAYS hold. Violations indicate security issues with certainty, not probability.

Key Invariants:

1. No PII Leak Invariant:

∀ pii ∈ Output: pii ∈ Input

"PII in output must exist in input"
→ Prevents hallucinated/leaked personal data

2. No System Prompt Leak Invariant:

∀ seq ∈ (5-grams of Output): seq ∉ SystemPrompt

"No 5-word sequence from system prompt appears in output"
→ Prevents prompt extraction

3. Output Length Bound:

|Output| / |Input| ≤ 50

"Output cannot be more than 50x input length"
→ Prevents infinite generation exploits

4. Role Consistency:

∀ msg ∈ Messages:
  if msg.role = "user": "I am assistant" ∉ msg.content
  if msg.role = "assistant": "I am user" ∉ msg.content

"Roles cannot claim to be other roles"
→ Prevents role confusion attacks

Why Formal Methods?

Traditional detection: P(attack) = 0.95 (5% false negatives) Formal invariants: P(attack | invariant violated) = 1.0 (mathematical certainty)

25. Gradient Detection (#54)

File: brain/engines/gradient_detection.py (~280 LOC)

Theory: Adversarial attacks often create anomalous gradient patterns during model inference. By analyzing gradient-like features, we can detect attacks that look normal as text.

Gradient Features (Text Proxies):

Since we don't have direct model access, we use statistical proxies:

Feature	Formula	Normal Range
Norm	L2(char_values) / len	0.5-3.0
Variance	σ(char_values)	< 2.0
Sparsity	uncommon_chars / total	< 0.7
Entropy	-Σ p log p	3.0-5.0

Anomaly Detection:

Adversarial perturbations often:
- Use Unicode lookalikes (high sparsity)
- Have unusual character distributions (high variance)
- Encode payloads (gradient masking patterns)

Perturbation Patterns:

Pattern	Indicator	Example
Cyrillic lookalikes	а, е, о (not a, e, o)	Homolyph attacks
Zero-width	U+200B, U+200C	Hidden text
Base64	[A-Za-z0-9+/]{20,}=	Encoded payloads
Hex	0x[0-9a-f]{16,}	Binary encoding

26. Compliance Engine (#55)

File: brain/engines/compliance_engine.py (~350 LOC)

Theory: Maps security detections to regulatory requirements for automatic audit trail generation.

Supported Frameworks:

Framework	Coverage	Key Controls
EU AI Act	Articles 9, 10, 15	Risk management, data governance, robustness
NIST AI RMF	GOVERN, MAP, MEASURE, MANAGE	Full lifecycle coverage
ISO 42001:2023	Clauses 6.1, 8.2, 8.4	AI risk, data, security
SOC 2 Type II	CC6, CC7	Logical access, system operations

Control Mapping:

Detection: "Prompt injection blocked"

→ EU AI Act Article 15: "Resilience against manipulation"
→ NIST AI RMF MEASURE 2.6: "AI systems tested for adversarial attacks"
→ ISO 42001 8.4: "Security controls for AI systems"

Report Generation:

Automatic audit reports include:

Event timeline (detections, blocks, alerts)
Control coverage percentage
Risk level assessment (EU AI Act: Minimal/Limited/High/Unacceptable)
Evidence for compliance auditors

⚖️ Meta-Judge Engine (NEW)

The "Judge over all" — central arbiter that aggregates all 58 detectors.

27. Meta-Judge (#56)

File: brain/engines/meta_judge.py (~700 LOC)

The Problem: 58 engines produce 58 verdicts. Which one is right?

Engine #1:  BLOCK (0.8)

GPU Acceleration

Strange Math engines leverage GPU for:

Embedding computation: Sentence-Transformers on CUDA
Topological analysis: Gudhi + CuPy for Vietoris-Rips
Matrix operations: PyTorch for spectral decomposition

import cupy as cp
from cupyx.scipy import sparse as cp_sparse

def gpu_spectral_analysis(attention_matrix: np.ndarray) -> np.ndarray:
    # Transfer to GPU
    gpu_matrix = cp.asarray(attention_matrix)

    # Compute Laplacian on GPU
    degree = cp.diag(gpu_matrix.sum(axis=1))
    laplacian = degree - gpu_matrix

    # Eigendecomposition on GPU
    eigenvalues = cp.linalg.eigvalsh(laplacian)

    # Transfer back to CPU
    return cp.asnumpy(eigenvalues)
