05 The shared planet-state

RAISE THE SKY.
THE WATER RETURNS.

One global state — how much pressure and warmth the network has added — and a waterline computed from it, never drawn. A point floods only when it is warm enough to melt and the air above it is thick enough to keep water liquid through the day, tested against its true NASA elevation. Warming floods the deep basins first; past 14.3% of the planet, today's air runs out and only added pressure can raise the line further. And it decays — stop computing, and the ocean recedes.

TODAY'S MARSDRAG TO TERRAFORM — THE PHYSICS ANSWERS
THIS IS THE SANDBOX. Same physics, same real NASA elevation — but the planet you move here is yours alone. The live shared planet — terraform projects funded in $MARS, era crossings named after the wallet that caused them, atmosphere that decays when the network stops — runs on the full build. Follow @MarscoinFun for when it goes public.
WHAT THIS IS, HONESTLY: a physics simulation over real NASA elevation. It maps where liquid water would be stable — the water itself would still have to be delivered. Decay is real (MAVEN measured Mars losing 1–2 kg/s to the solar wind) but accelerated ~107× here so it can be felt; half-life 45 days. Jakosky & Edwards (2018): accessible CO₂ on Mars is insufficient to terraform with present technology. $MARS on this page is the in-app simulation credit, not the on-chain token.
