The Pentagon, Claude, and the Case for Verifiable Constraints

The Pentagon reportedly wants to classify Anthropic as a supply chain risk. Anthropic wants guardrails on autonomous weapons. Both sides are right — and both are missing the same thing.

There's no technical enforcement layer between "what an AI provider allows" and "what a deployer actually does."

What Happened

Here's the story in brief:

1. The Pentagon embeds Claude in military systems via Palantir
2. Claude is allegedly used in operations where people die
3. An Anthropic executive calls Palantir to ask: "Did our AI help kill people?"
4. Defense Secretary Hegseth moves to classify Anthropic as a supply chain risk
5. The Pentagon's position: "all lawful purposes" or nothing

The fundamental problem: Anthropic had to phone someone to find out what their model was being used for. There was no technical mechanism to know — let alone prevent it.

The Trust Gap

Right now, the relationship between AI providers and deployers runs on:

• Terms of Service — a legal document
• Usage policies — words on a website
• Fine-tuning and RLHF — statistical alignment, not guarantees
• Phone calls — apparently

None of these are verifiable. None are enforceable in real-time. None produce cryptographic proof.

When the stakes are "did this model help kill someone," vibes-based governance isn't sufficient.

What Both Sides Actually Need

The Pentagon wants: Unrestricted capability for lawful operations, with proof of compliance.

Anthropic wants: Guarantees that their models aren't used for things they prohibit, with proof of adherence.

These aren't contradictory. They're both asking for the same thing: verifiable constraints with auditable proof.

What Verifiable Constraints Look Like

Imagine if, instead of Terms of Service, there was a cryptographically enforced contract between Anthropic and Palantir:

model DeploymentContract {
  initial active

  // Any use requires human authorization
  active -> active [+signed_by(/oversight/authorized_operator.id) -modifies(/constraints)]

  // Constraint changes require both parties
  active -> active [+modifies(/constraints) +all_signed(/parties)]
}

rule human_in_the_loop {
  formula {
    always (+modifies(/actions/kinetic) implies +signed_by(/oversight/human_commander.id))
  }
}

rule audit_trail {
  formula {
    always (+any_signed(/parties))
  }
}

This isn't a suggestion or a policy. It's a state machine with rules that are:

• Cryptographically signed by both parties
• Permanently enforced — rules can't be removed once added
• Independently verifiable — either side can prove compliance
• Tamper-proof — append-only log of every action

Anthropic doesn't need to call anyone. The log tells them exactly what happened. The Pentagon doesn't need to worry about surprise restrictions. The contract defines the boundaries upfront.

"But You Can't Contract-Wrap a Neural Network"

Fair objection. You can't put formal constraints inside a language model's weights. But you can put them around the deployment:

• Every API call passes through a verification layer
• Every action the model proposes gets checked against the contract
• Every decision with lethal implications requires a signed human authorization
• Every override is logged immutably

The model itself remains capable. The constraints operate at the deployment layer — where the decisions actually happen.

This is exactly how formal verification works in hardware. You don't make transistors "aligned." You prove the circuit satisfies its specification. The same principle applies to AI deployment.

Why This Matters Beyond the Military

The Pentagon-Anthropic conflict is dramatic, but it's a preview of a universal problem:

• Enterprises deploying AI agents that handle customer data
• Financial institutions using AI for trading decisions
• Healthcare systems where AI assists diagnosis
• Any multi-agent system where agents from different organizations interact

In every case, the question is the same: How do you prove that an AI system operated within its agreed-upon constraints?

Reputation? Audits? Compliance checklists? These are the "phone call" approach scaled up. They work until they don't — and when they don't, people get hurt.

The Path Forward

We're building Modality because we believe the trust problem is foundational. Not just for agents cooperating with each other, but for the entire stack:

• Human ↔ AI — "I deployed this model with these constraints, here's the proof"
• AI ↔ AI — "We agreed to this contract, every action is signed"
• Organization ↔ Organization — "Our deployment complies, here's the verifiable log"

The Pentagon shouldn't have to trust Anthropic's word. Anthropic shouldn't have to call Palantir to find out what happened. And the public shouldn't have to hope that everyone involved did the right thing.

Math doesn't have opinions. Proofs don't need phone calls. Contracts don't forget.

That's what we're building toward.
