Runtime Active

Deterministic
Runtime for
AI Agents

Stop trusting LLMs. Start constraining them.
Every decision enforced — not suggested.

The Problem

LLMs don't follow rules.
They approximate them.

They hallucinate

Confident lies with citations

They get injected

One prompt to bypass everything

They break silently

No error. No log. Just wrong.

And yet, we hand them real-world decisions.

This is the flaw.

Paradigm Shift

AI doesn't need
better prompts.

It needs laws.

Execution Model

Lawful State Evolution

AI systems no longer try to follow rules. They are structurally incapable of violating them.

The Solution

Not a wrapper. Not a filter.

A runtime.

Enforce

Constraints live outside the model. The model's opinion is irrelevant.

Verify

Z3 theorem prover validates every policy. Mathematically. Before deployment.

Block

Invalid actions die before execution. No recovery needed. No damage done.

How It Works

Three steps. Zero trust in the model.

01

Define Constraints

Write policies in CSL — Constraint Specification Language. Human-readable. Machine-enforceable. Not a prompt. A specification.

STATE_CONSTRAINT limit {
  WHEN role == "MANAGER"
  THEN amount <= 250000
}
02

Verify Correctness

Z3 theorem prover checks reachability, consistency, and conflict-freedom. Your policy is mathematically proven correct before a single agent runs.

$ chimera-runtime verify policy.csl
  Syntax     ✓
  Z3 SAT     ✓ Consistent
  Conflicts  ✓ None found
03

Enforce at Runtime

Every agent action passes through the constraint guard. The guard is deterministic. Not probabilistic. Not negotiable.

Agent: transfer($500K)
Guard: BLOCKED [manager_limit]
→ amount 500000 > limit 250000
→ Audit record: dec_8f3a2b...

No exceptions. No bypass.

Before Chimera

“The model should follow this rule...”

After Chimera

“The system cannot violate this rule.”

For Developers

Three lines. Full constraint.

Not just enforcement — visibility

Decisions

ALLOW / BLOCK in real-time

Full causal reasoning chain

Intervention

Halt, override, resume

Fleet

Multi-agent monitoring

Causal Intelligence

Beyond guardrails.

Chimera doesn't just stop violations. It explains them.

Why a violation happened
Which constraint triggered it
What causal chain led there

This is not explainability. This is causal accountability.

EU AI Act

Compliance is a consequence — not the product.

When you enforce deterministic constraints by design, compliance follows automatically.
