#1871
Changed the parse_run_traces function, to include the last 4 letter of the run_id of the trace, result of which is a unique key for every call.

Hi @jjmachan, can you help me with this one, all the unit test have failed because of the PR #1879

The code changed was small
From this

def validate_samples(self, samples: t.List[Sample]) -> t.List[Sample]:
    """Validates that all samples are of the same type."""
    if len(samples) == 0:
        return samples

    first_sample_type = type(self.samples[0])
    if not all(isinstance(sample, first_sample_type) for sample in self.samples):
        raise ValueError("All samples must be of the same type")

    return samples

to this

def validate_samples(self, samples: t.List[Sample]) -> t.List[Sample]:
    """Validates that all samples are of the same type."""
    if len(samples) == 0:
        return samples

    first_sample_type = type(samples[0])
    for i, sample in enumerate(samples):
        if not isinstance(sample, first_sample_type):
            raise ValueError(f"Sample at index {i} is of type {type(sample)}, expected {first_sample_type}")

    return samples

which does not change much of the functionality of comparing classes while iterating
