For each deletion set compute all external cells whose every baseline-pair blocker is hit, filter by current row/column deficits, and measure eligible count versus required r+2 additions plus uncovered-axis deficits. Save each radius's best deletion set/domain and exact timing. Independently recount best states with determinants. Only if a domain reaches necessary count and axis coverage, run a restricted exact repair and two independent whole-set checkers before considering a candidate. This changes the radius and objective from SOL168's radius9 cover-guided sample; it does not repeat Luna's small-exchange or unstructured annealing experiments.
