  - Replaced linking ordering’s column-presence behavior with resolver-driven utility selection and explicit
    deterministic fallback when selected utility is fully non-finite (fallback to u0, then lexical tie-break).
      - File: R/adaptive_round_candidates.R
  - Updated step logging semantics:
      - utility_mode now comes from resolved selection mode, not controller$cross_set_utility.
      - cross_set_utility_pre is populated only for linking-mode cross-set evaluation path.
      - Non-cross-set rows may carry pairing utility modes.
      - File: R/adaptive_step.R
  - Hardened utility config handling to canonical linking utility naming (with legacy alias normalization).
      - File: R/adaptive_state.R
  - Made linking inference contract explicit as MAP + Hessian/Laplace approximation in linking refit contract metadata
    and comments.
      - File: R/adaptive_btl_refit.R
  - Reconciled roxygen docs to mode-specific utility semantics and removed stale cross_set_utility wording from
    exported docs sections.
      - File: R/adaptive_run.R
      - Generated docs: man/adaptive_rank_start.Rd, man/adaptive_rank_run_live.Rd
  - Added/updated tests for:
      - new utility_mode values,
      - pairing-vs-linking utility separation,
      - deterministic non-finite linking utility fallback,
      - independent spoke stage progress isolation check.
