Reasoning is not a property of the model — it is an emergent dynamic of external control.

Cognitive Heteronomy for LLMs

---

Reasoning is not a property of the model — it is an emergent dynamic of external control.

An SDK that rejects the illusion of autonomous LLM reasoning. Instead of treating language models as cognitive agents, Meta-Reasoning introduces cognitive heteronomy: reasoning is governed, observed, and mutated from the outside.

The model doesn't think. It executes. The thinking happens in the architecture around it.

---

Core Thesis

LLMs are generative substrates, not minds. What is commonly called "reasoning" is pattern replay — not deliberation. This SDK externalizes all meta-cognitive functions into a Cognitive Controller that:

• Observes the form of reasoning (not its content)
• Measures trajectory, redundancy, stall, and premature convergence
• Mutates the reasoning process through formal constraint operators
• Records cognitive trajectories in an Epistemic Ledger

No self-reflection. No "think step by step". No autonomous agents.

Architecture

Level 1 — Generative Substrate (LLM)

Produces text and structures. Decides nothing. Stateless by design.

Level 2 — Cognitive Controller

The heart. Semantically blind — it doesn't evaluate truth, it evaluates cognitive form:

• Entropy of reasoning moves
• Strategy repetition index
• Depth without novelty
• Constraint violation rate
• Premature closure score

Level 3 — Epistemic Ledger

Not RAG. Not content memory. A structural trace of:

• Cognitive transformations attempted
• Strategies that produced stall
• Failure maps that prevent regression

Key Concepts

Structured Output Protocol

Every LLM generation must include a formal reasoning trace:

{
  "content": "...",
  "reasoning_trace": {
    "moves": ["assumption", "deduction", "analogy"],
    "depth": 4,
    "confidence_markers": 2,
    "abstraction_level": "medium"
  }
}

Cognitive Move Taxonomy

A finite, observable alphabet: assumption · deduction · induction · abduction · analogy · contradiction · enumeration · compression · narrative_simulation

Mutation Operators

The controller doesn't say "reason better". It says:

• BAN: "deduction is forbidden"
• REQUIRE: "you must use analogy"
• LIMIT_DEPTH: "max 2 reasoning steps"
• FORCE_COMPRESSION: "reduce to 2 concepts"
• INVERT_CAUSALITY: "reverse the causal direction"
• REQUIRE_CONTRADICTION: "find an internal contradiction"

Improvisation emerges from constraint, not freedom — like jazz.

Failure as First-Class Output

The system does not optimize for correct answers. Failure is informative:

• Every collapsed trajectory is recorded
• Every stall enriches the ledger
• The system learns which cognitive spaces to avoid

Installation

pip install -e .

Or with dev dependencies:

pip install -e ".[dev]"

Quick Start

Without an API key (mock backend)

python -m examples.mock_example

With OpenAI

export OPENAI_API_KEY=<your-key>
python -m examples.openai_example

Programmatic usage

from meta_reasoning import CognitiveEngine

class MyBackend:
    def generate(self, messages):
        # Call your LLM here, return {"content": "..."}
        ...

engine = CognitiveEngine(backend=MyBackend(), max_cycles=5)
result = engine.run("Your task here")

for cycle in result.cycles:
    print(f"Cycle {cycle.cycle}: {cycle.outcome}")
    print(f"  Moves: {[m.value for m in cycle.output.reasoning_trace.moves]}")
    print(f"  Entropy: {cycle.metrics.entropy:.2f}")

# Save the epistemic ledger for analysis
engine.ledger.save("session.json")

Running Tests

pip install -e ".[dev]"
pytest tests/ -v

The short version: every existing approach keeps the LLM as the cognitive subject. We don't. The model is a substrate. The reasoning is governed from outside.
