# pageindex/page_index_md.py
# Deprecation shim. The Markdown indexing pipeline now lives in
# pageindex/index/page_index_md.py (the single source of truth). This module
# re-exports it so legacy imports keep working.
#
# The canonical md_to_tree takes booleans; legacy callers passed 'yes'/'no'
# strings, so the wrapper below coerces them (a bare 'no' is otherwise truthy).
