What it measures
Raven-style 3×3 matrix puzzles, freshly generated each session so scores stay comparable across unlimited retakes.

Validity & honesty
Items are procedurally generated, not a published test, so there are no population norms — scores are meaningful as your own trend over time, not as an IQ. Reliability for change badges is an assumed estimate (0.85) until your own data allows an empirical one.
Cadence: a retake every 2 days is advised. You can retake anytime — early retakes are scored normally and flagged in trend analysis.
