Purpose: summarize how features were selected and classified.

• Structural relevance for scenario identity.
• Cross-family usefulness (corpus-wide behavior).
• Interpretability for review and reproducibility.
• Redundancy control inside the core set.

• Keep core compact (core23) for methodological clarity.
• Keep extended (full46) for richer diagnostics and complementary analysis.
• Track residual dependencies explicitly (not hidden).
