# rate-receipt

Same kernel as `process-calc`, but every call returns a **receipt**:
seed, value, channel, rate, gauge yes/no.

```python
from receipt_calc import mix, receipt
print(receipt(lambda x: mix(x, x), 3))
```

Empty seeds and seed 0 are θ. Float is θ.

Not an LLM. Sister of `process-calc`.
