Across 300 sampled payloads from today, `sigma_c_estimate` was pinned at the 3.2 scan ceiling in 293 of the 300 sampled 2048-site runs, with the remaining sampled 64- and 512-site runs only slipping slightly to about 3.19375 or 3.2. The operator was strongly reactive and bridge-loaded throughout, with `last_reactive_eval` about 33.85 to 33.86 and `last_bridge_ratio` about 7.76 at 2048 and even larger bridge ratios about 13.84 to 14.05 at 64, while `last_ridge_mass` stayed high around 0.503 at 2048 and about 0.65 at 64. But `last_coast_interior_balance` never approached the 0.46 target and instead stayed only about 0.313 at 2048 and about 0.099 to 0.103 at 64, so the amplified mode remained coast-and-ridge heavy rather than becoming a balanced coastal-ridge-interior bridge.
