unitarity-labs 3.1.5

Experimental multi-model runtime for transformer instrumentation, latent alignment tracing, distributed coordination

unitarity-lab

A runtime for instrumenting Hugging Face transformer models and measuring cross-layer alignment during inference, with passive (metrics-only) and active (intervention) modes.

Status

Alpha software. APIs may change between releases. Benchmark results are preliminary. Use at your own discretion.

---

What it does

• Attach forward-pass hooks to any Hugging Face AutoModelForCausalLM and measure cross-layer alignment (Manifold Coherence zeta) between a source and sink layer.
• Run in passive mode (hooks capture metrics only, no tensor mutation) or active mode (LoRA-adapted bridge bias injection, flux governor, mirror feedback).
• Coordinate two model instances over ZeroMQ for distributed inference with Byzantine fault tolerance (--dual).
• Auto-detect hardware (CPU, laptop GPU, prosumer GPU, server GPU) and select precision class (FP32, BF16, INT4) accordingly.
• Monitor runtime health with a Rich terminal dashboard (--dashboard).
• Run reproducible benchmark harnesses (GSM8K, HumanEval+, Agent Instruct, Adversarial Safety) comparing passive vs active modes.
• Fine-tune toward GUE spectral rigidity targets using the included GUELoss objective.

pip install unitarity-labs

Install from source

git clone https://github.com/holeyfield33-art/unitarity-lab.git
cd unitarity-lab
pip install -e .

pytest tests/ -v

The console script unitarity-start is installed automatically and is equivalent to python start_node.py:

unitarity-start --help

Quick start

Run the simplest possible session (active mode, auto-detected hardware, default model and prompt):

python start_node.py

Passive mode (metrics only, no tensor mutation):

python start_node.py --mode-passive

Custom prompt:

python start_node.py --prompt "Summarize the theory of relativity in two sentences."

With the terminal dashboard:

python start_node.py --dashboard

---

Run commands

Local passive mode

python start_node.py --mode-passive

Custom model override

python start_node.py --model "gpt2"

Custom precision override

Distributed mode

unitarity-lab supports dual-node coordination over ZeroMQ. Two model instances (Node A and Node B) exchange Krylov-subspace compressed activations for cross-model alignment. This mode enables distributed inference experiments with precision handshake, adaptive epoch tuning, and Byzantine kill-switch voting.

Node A (relay)

python start_node.py --dual --node-id A

Node B (peer)

python start_node.py --dual --node-id B

Both nodes must be reachable on their respective ZeroMQ ports (default: 5555/5556).

Benchmark output fields

Field	Description
zeta	Manifold Coherence zeta -- flattened cosine similarity between source and sink layer activations. Range: [-1, 1].
baseline_cosine	Cosine similarity computed on mean-pooled activations. A simpler baseline for comparison.
permutation_p	p-value from a permutation test (null hypothesis: observed zeta is no different from random permutations). Lower values indicate the alignment is unlikely to be noise.
latency_ms	Wall-clock latency per sample in milliseconds.
accuracy	Task-specific accuracy (exact match for GSM8K, pass@1 for HumanEval+, etc.).

Note: the current benchmark harnesses use synthetic tensors to demonstrate the metric pipeline. Full evaluation requires a dataset and a loaded model.

Architecture

core/        Production modules. Metrics, bridge, hooks, dashboard,
             flux governor, mirror feedback, precision handling,
             kill switch, spectral analysis, and GUE loss.
             Must have tests. No breaking changes without a version bump.

dist/        Distributed coordination. ZMQ dual-link, precision
             handshake, ChronosLock temporal sync, tier manager.
             Not required for single-node use.

labs/        Experimental and unstable. Mirror, flux, semantic lock
             wrappers, topology metrics (spectral gap, Betti-0,
             activation entropy). May change or be removed.

benchmarks/  Evaluation harnesses with shared metric helpers.
             GSM8K, HumanEval+, Agent Instruct, Adversarial Safety.

tests/       pytest suite covering core modules.

Manifold Coherence zeta

The primary metric is Manifold Coherence zeta -- the cosine similarity between the flattened hidden states of two transformer layers (source and sink):

$$ \zeta = \frac{\operatorname{vec}(H_{\text{source}}) \cdot \operatorname{vec}(H_{\text{sink}})} {|\operatorname{vec}(H_{\text{source}})| ;|\operatorname{vec}(H_{\text{sink}})|} $$

In plain terms: zeta measures how similar the internal representations are at two different depths of the model. A value near 1.0 means the layers are highly aligned; a value near 0.0 means they are largely independent.

A permutation test (permutation_test_zeta) is included to evaluate whether an observed zeta value is statistically significant compared to random permutations.

Disclaimer: zeta is a cosine-similarity proxy for cross-layer alignment. It is not a measure of entanglement, consciousness, or any physical phenomenon. Treat it as an empirical diagnostic whose relationship to model quality is under investigation.

Geometric Brain framework

The repo includes the Geometric Brain framework for measuring and enforcing GUE (Gaussian Unitary Ensemble) spectral rigidity in transformer latent spaces.

GUELoss is a differentiable fine-tuning objective that penalizes deviation from the GUE target spacing ratio:

from core.gue_loss import GUELoss

criterion = GUELoss(target_r=0.578)
loss, r_measured = criterion(lora_B @ lora_A)
loss.backward()

See GEOMETRIC_BRAIN.md for the full theory, methodology, and SHI leaderboard.

Hardware and model notes

• CPU vs GPU: start_node.py auto-detects CUDA availability. If no GPU is found, it falls back to FP32 on CPU.
• Auto precision: GPU VRAM is queried at startup. Less than 8 GB selects INT4 (quantized). 8--24 GB selects BF16. 24 GB or more selects BF16. CPU falls back to FP32.
• Default models: INT4 uses unsloth/Llama-3.2-1B-bnb-4bit. BF16 and FP32 use meta-llama/Llama-3.2-1B.
• Hugging Face access: The default Llama models may require a Hugging Face access token. Set HF_TOKEN or use huggingface-cli login. Alternatively, pass any public model via --model.
• Override model: --model <hf_model_id> to use any HuggingFace causal LM.
• Override precision: --precision INT4|FP8_E4M3|BF16|FP32 to bypass auto-detection.
