TF-Agents BoundedArray minimum value

Question

I'm looking for information on how TF-agents handle Observation values if they are lower that the BoundedArraySpec minimum. My observation spec contains 3 array specs, each defined like:

'url1_m1':array_spec.BoundedArraySpec(shape=self.p_data_url1_m1.shape, dtype=np.float32, minimum = 0, name='url1_m1')

During training, and publishing the model negative values may be passed in (I have now changed the minimum value). I'm wondering how do TF-agents handle the negative values. Does it treat them as zero as the minimum allowed value?

Both training and published models function from previous version, and no error notified.
