Overview

Entanglements

When designing delegation architectures, it’s tempting to treat components as independent—to assume that stacking five 90%-effective safety layers yields 99.999% protection. In practice, components become entangled in ways that undermine this assumption.

Entanglements come in many forms:

Shared dependencies: Components rely on the same infrastructure, training data, or assumptions
Information leakage: What one component knows affects another’s behavior
Active influence: Component X can affect Component Y’s decisions (the “bureaucrat problem”)
Correlated failures: The same inputs defeat multiple layers simultaneously
Collusion potential: Components might coordinate against the principal’s interests

Understanding and managing these entanglements is one of the hardest problems in delegation architecture design.

The Independence Illusion

Consider a “Defense in Depth Stack”:

flowchart TB
    subgraph Independent["Independent Model (Idealized)"]
        L1["Layer 1: 90% effective"] -->|"10% pass through"| L2["Layer 2: 90% effective"]
        L2 -->|"1% pass through"| L3["Layer 3: 90% effective"]
        L3 -->|"0.1% pass through"| OUT["Combined: 99.9% effective"]
    end

    style L1 fill:#ccffcc
    style L2 fill:#ccffcc
    style L3 fill:#ccffcc
    style OUT fill:#99ff99

But if layers are entangled:

flowchart TB
    subgraph Entangled["Entangled Model (Reality)"]
        L1C["Layer 1: 90% effective"]
        L2C["Layer 2: 90% effective"]
        L3C["Layer 3: 90% effective"]
        TANGLE["Entanglement:<br/>Shared blind spots,<br/>cross-influence,<br/>common dependencies"]
        L1C --> TANGLE
        L2C --> TANGLE
        L3C --> TANGLE
        TANGLE --> OUTC["Combined: 95% effective<br/>(not 99.9%)"]
    end

    style L1C fill:#ffe6cc
    style L2C fill:#ffe6cc
    style L3C fill:#ffe6cc
    style TANGLE fill:#ffcccc
    style OUTC fill:#ff9999

The gap between perceived and actual protection can be enormous—often 10× to 100× worse than the independent model predicts.

The Bureaucrat Analogy

To understand entanglements, it helps to think about how human bureaucracies fail. Consider a government office where Clerk A prepares cases and Reviewer B approves them.

Passive entanglement: Both Clerk A and Reviewer B were trained at the same institution and use the same manual. They share blind spots—certain types of fraud that neither was taught to recognize.

Active entanglement: Clerk A prepares summaries that Reviewer B reads. Even without any malicious intent, A’s framing shapes B’s perception. The summary emphasizes what A found important.

Adversarial entanglement: After working together for years, A and B have developed an “understanding.” A knows exactly how to word things for approval, and B has learned to trust A’s judgment. Neither explicitly agreed to anything, but the effect is that A’s cases are rubber-stamped.

This analogy maps directly to AI systems:

Clerks and reviewers → Agents and verifiers
Shared training → Same LLM provider, same prompts
Case summaries → Context passed between components
Long-term relationships → Persistent agent-verifier pairings

The bureaucrat lens helps identify entanglements: “How might Component X influence Component Y? Through what channels? With what incentives?”

Types of Entanglement

Passive Entanglements

Components share something that creates correlated behavior (like clerks trained at the same school):

Shared training data: Multiple AI components trained on similar datasets
Common infrastructure: Same cloud provider, same LLM API, same database
Shared assumptions: Designed by the same team with the same blind spots
Environmental coupling: Both affected by the same external conditions

Active Entanglements

One component directly affects another (like a clerk’s summary shaping a reviewer’s decision):

Information flow: Output of Component A becomes input to Component B
Influence channels: Component A can signal or communicate with Component B
Resource competition: Components compete for the same limited resources
Authority relationships: Component A has power over Component B’s operation

Adversarial Entanglements

Entanglements that can be exploited (like capture or collusion between clerk and reviewer):

Collusion potential: Components might coordinate against oversight
Capture risk: One component might be “captured” by another’s interests
Side-channel communication: Hidden information channels between components
Cascading compromise: Compromising one component enables compromising others

Why This Matters

False confidence: Teams believe they have robust multi-layer protection when components are actually entangled in ways that defeat the layering.

The bureaucrat problem: In human organizations, we understand that bureaucrat X might influence bureaucrat Y through formal channels, informal relationships, shared incentives, or implicit threats. AI components have analogous dynamics.

Resource misallocation: Adding more layers of the same type provides diminishing returns. Resources might be better spent on genuinely independent approaches.

Audit failures: Security reviews that examine each component independently will miss systemic vulnerabilities in how components interact.

The Entanglement Tax

We define the Entanglement Tax as the ratio of actual risk to perceived risk:

Entanglement Tax = Actual_Delegation_Risk / Perceived_Delegation_Risk

In the example above:

Perceived risk: 0.1% (99.9% protection)
Actual risk: 5% (95% protection)
Entanglement tax: 50×

Your actual risk is 50× higher than your independent model suggests.

This “tax” compounds with system complexity. Organizations with many composed patterns and high assumed protection levels may be paying entanglement taxes of 100× or more.

Quick Diagnostic

Before reading further, assess your current architecture:

Question	Entanglement Type
Do multiple verification layers use the same LLM provider?	Shared infrastructure
Were all safety components designed by the same team?	Organizational entanglement
Do later stages receive context from earlier stages?	Information flow
Can one component affect another’s resource allocation?	Active influence
Has the architecture been “optimized” for performance?	Emergent coupling
Can your red team find inputs that evade multiple layers?	Correlated blind spots
Could components benefit from coordinating against you?	Collusion potential

If you answered “yes” to 3+ questions, entanglement is likely a significant source of unrecognized risk in your system.

Key Takeaways

Independence is the exception, not the rule. Assume entanglement until proven otherwise.
Entanglement is broader than correlation. It includes active influence, information flow, and potential collusion—not just shared failure modes.
The bureaucrat analogy helps. Ask: “How might Component X influence Component Y? What channels exist? What incentives?”
Entanglement is measurable. Use the tools in this section to quantify your entanglement tax rather than guessing.
Some entanglement is irreducible. At the limit, all AI verification of AI may share fundamental limitations. Know where those limits are.
The honest answer is sometimes “we can’t isolate this.” Better to know your limitations than to believe in illusory independence.
