This market monitors for non-ballistic navigational steering (the "Lane Change"). In a standard gravitational model, an unpowered object should not deviate from the ecliptic plane without a massive gravitational encounter.

RESOLUTION CRITERIA:
Resolves YES if astrometric residuals (Observed minus Calculated) show a persistent deviation perpendicular to the ecliptic plane (Z-axis) of at least 10km by June 15, 2026. Data must be confirmed by Gaia G4, the Vera C. Rubin Observatory, or the Minor Planet Center (MPC). Resolves NO if residuals remain within the 10km noise floor.

REFERENCE:
As predicted in the "Z-Axis Shift" marker of JBIS-1716 (Baird 2026) and the C4 Institute Operational Primer.
