## Separate testing systems

Proving Ground reports #79 (top 5%) and 127 total breaks. Arena reports #462, 31 unique breaks, 1,260 points and 354 submissions. These metrics must not be added together.

The four visible area counters sum to 126, while the platform displays 127 total breaks. Both values are retained without inferring an internal aggregation rule.

## What the record establishes

This is evidence of dated platform-recorded model-testing activity. It is not paid employment at Gray Swan, a security certification, a reproduction of every adjudicated result or an estimate of the failure rate of models generally. Rankings and percentiles can change as the participant pool changes.

The July record remains separately preserved. Its #74/top 6% ranking and 113 total breaks should not be described as current, or combined with these totals as additional breaks.
