schedopt-v3-search

Phases C and D of the v3 campaign. The search space is a staged hierarchy — a four-parameter warmup-stable-decay envelope, an envelope-plus-teeth modulation nesting the v2 winners, and a gated free-form per-waypoint family — searched with a Gaussian-process surrogate whose censored log-time likelihood scores did-not-finish seeds correctly, under Thompson sampling on the posterior of the censored 90th-percentile crossing time. A parametric response surface, population-based training, and a random-schedule control run alongside as cheap cross-checks. The selected arms then face one held-out confirmation on a fresh paired seed cohort, adjudicated by paired restricted-mean survival differences, weighted log-rank tests, almost-stochastic-order dominance, and winner's-curse shrinkage; search-pool numbers are never reported as results.
