# Scenario 06: Search, Index & Catalog
# ============================================================================
# Commands: glob, grep (-i, -n, -C, -f, -l, -c), search init, search index,
#           search query, search stats, reindex, catalog, aspects, lineage,
#           graph
# TUI Tab: 7 (Search)
#
# Story: Use glob/grep to explore demo data, initialise keyword search,
#        index files, query, then inspect catalog metadata and lineage.
