# MaleCNS LIF Phase 4A

Auditable, single-RTX-4090 whole-connectome LIF baseline. It consumes only the
validated Phase 3B neuron-only products and never writes to the dataset tree.

Run with the exact GPU UUID to prevent accidental V100 or mixed-GPU use:

```bash
CUDA_VISIBLE_DEVICES=GPU-79f3a85d-adce-7833-7003-6488140ca596 \
  .venv/bin/python phase4a.py \
  --config /data/digital-drosophila/experiments/phase4a-baseline/config/baseline.yaml
```

The raw `int64` synapse-count array remains read-only. The configured transform
creates a separate signed `float32` effective-weight array. Spike output is a
sparse Parquet event table, never a dense time-by-neuron matrix.

The baseline parameters are FlyWire-inspired modeling defaults, not MaleCNS
single-cell measurements. Synthetic drive amplitudes are deterministic smoke-test
inputs and are not a biological calibration.
