Changes in version 0.6.0                        

New features

  - baseline_model() now checks nuisance_list inputs during construction
    for zero-variance columns, duplicate or near-duplicate columns,
    non-finite values, nuisance rank deficiency, and columns aliased
    with baseline terms.
  - Added nuisance_check = c("warn", "error", "drop", "none") to control
    whether nuisance problems warn, stop, are dropped with an audit
    warning, or are skipped.
  - Added check_nuisance() and clean_nuisance() helpers for inspecting
    and repairing block-wise nuisance regressors before model
    construction.

Bug fixes

  - Fixed list-based event_model() specifications so hrf(..., subset = )
    expressions can use base operators and helper functions from the
    calling environment, matching formula-interface subset behavior.
  - Fixed event-model column metadata construction for factor and
    multi-basis HRF terms that expand to multiple design columns.
