"""Ingest EU act recitals via the RecitalIngester engine (Parser 2).

Downloads each act's XHTML (CELLAR), parses the recitals (Erwägungsgründe),
self-tests, and uploads them as a SEPARATE interpretative source
(source_class=recital, use_for_primary=false). Acts whose recitals already
exist are SKIPPED — no automatic re-ingest.

Usage (Mac Mini, with the RAG service reachable):
    python3 control-pipeline/scripts/ingest_recitals.py --dry-run
