# Churn-percolation study: where does the responsive sub-graph shatter? # # Unresponsive nodes relay nothing, so the network that actually carries a flood is the sub-graph # induced on the responsive nodes. That is site percolation on a random d-regular graph, which has # a giant component only while the responsive fraction exceeds 1/(degree-1) -- i.e. the network # survives churn up to u_c = 1 - 1/(degree-1). This config walks u across that threshold for every # degree to locate the collapse (degree 3 breaks at 0.5, degree 6 at 0.8, degree 16 at 0.93). # # blend_hops=1 isolates the flood (one relay, no extra path fragility) and keeps the cost low; # 800 rounds x 8 seeds = 6400 rounds per cell. Coverage right AT the threshold is genuinely # bimodal across topologies (critical behaviour), so seed spread there is physics, not noise. n_nodes: [100000] degree: [3, 4, 6, 8, 12, 16] blend_hops: [1] max_blend_delay: [0] unresponsive_frac: [0.0, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9] redundancy: [1] f_adv: [0.1] adversary_mode: [random] seeds: 8 base: n_rounds: 800 n_placements: 1 worstcase_max_n: 100000
