as_spm_result() provides a validated common result format for projection model backends while preserving model-specific columns.
runSPM() now dispatches through internal model adapters and returns an spm_result while remaining compatible with legacy ADMB and experimental RTMB calls.
tier3_scenario_table() summarizes simulation output into assessment-ready rows for the seven Tier 3 projection alternatives.

The experimental RTMB path can reuse existing output when rendering its comparison vignette. This path remains a simplified prototype and is not yet a full RTMB translation or numerically equivalent replacement for the ADMB model.
