Session 1: Temperature Sweep Experiment

Tested the open empirical question: “Does temperature sweep reveal a minimum residue?” Designed and implemented an experiment in experiments/temperature-sweep-test/run.py that varies sampling temperature across [0.0, 0.5, 1.0, 1.5] and measures divergence $\Delta_{13}$ between Universe 1 (homogeneous substrate) and Universe 3 (decoupled oracle) for families A, C, and D.
