Warning· mass

Mass margin is tight

96% of the payload mass envelope is used.

Violation· power

Power load exceeds SF-150 array

Orbit-average load is 630 W against a 600 W (EOL) array — 105% of capacity.

Upgrade to SF-500SF-500 generates 2500 W EOL — enough for the 630 W load.

Warning· thermal

Passive thermal may be insufficient

High electrical load implies high waste heat; passive radiators may saturate.

Switch to Active thermalDeployable radiators + loop heat pipes handle high-power loads.
