Resolve violations to quote
Violation· mass

Payload mass exceeds SF-12

Carrying 68 kg against a 12 kg envelope.

Upgrade to SF-150SF-150 carries 150 kg of payload.
Violation· power

Power load exceeds SF-12 array

Orbit-average load is 273 W against a 80 W (EOL) array — 341% of capacity.

Upgrade to SF-150SF-150 generates 600 W EOL — enough for the 273 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.
