- Added canonical selection utility resolver and mode mapping:

[shmercer]

• pairing_trueskill_u0
  - pairing_trueskill_u
  - linking_cross_set_p_times_1_minus_p
  - NA
  - Files: R/adaptive_select.R, R/adaptive_step.R
  • 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.
