threshold-mod12
Trivial case: computes Hamming weight mod 12 for 8-bit inputs. Since max HW is 8 < 12, this is just HW.

HW (= HW mod 12)
Why Trivial?
For mod m where m > (number of inputs), no reset ever occurs:
- 8 inputs → max HW = 8
- 8 mod 12 = 8 (no wraparound)
Parameters
| Weights | [1, 1, 1, 1, 1, 1, 1, 1] |
| Bias | 0 |
| Total | 9 parameters |
Usage
from safetensors.torch import load_file
import torch
w = load_file('model.safetensors')
def mod12(bits): # Actually just HW
inputs = torch.tensor([float(b) for b in bits])
return int((inputs * w['weight']).sum() + w['bias'])
