- Wrapper preflight validation and messaging in adaptive_rank():

[shmercer]

• Added early checks for linking mode combinations vs input set structure in R/adaptive_rank.R.
  - Clear wrapper-level errors for invalid run_mode / phase_a_mode / hub_id / spoke-count combinations.
  • Linking console parity updates:
    • Added linking context in step events (spoke/transform when cross-set) in R/adaptive_print.R.
    • Extended refit block output with a compact linking summary (active spokes, transform/refit/lock modes, link
      reliability/stop metrics, cross-set counts, escalation/taper) in R/adaptive_print.R.
    • Wired link-stage rows into refit block rendering in R/adaptive_run.R.
  • Wrapper + console tests:
    • Added linking wrapper E2E coverage (link one-spoke import, multi-spoke concurrent, preflight errors) in tests/
      testthat/test-5026-adaptive-rank-wrapper.R.
    • Added linking refit-console contract test in tests/testthat/test-5019-console-progress-and-refit-block.R.
    • Updated one mock signature for compatibility in tests/testthat/test-5047-adaptive-run-persist-simulation-
      branches.R.
  • User docs:
    • Updated wrapper docs/roxygen and regenerated man/adaptive_rank.Rd.
    • Added linking workflow/log interpretation sections in README.Rmd, README.md, and vignettes/adaptive-
      pairing.Rmd.
