GPT-5.6 Sol flagged a revealing pattern in K3's compute-growth sequence: 10^29→10^31→10^32→10^33 FLOP implies 100× growth in 2031-2036 but only 10× in each later five-year block — a deliberate slowdown that, if documented explicitly, would make the trajectory coherent rather than appearing as arbitrary deceleration — suggesting an implicit assumption about diminishing returns or physical constraints on compute scaling in later eras
