"""Build the Day-1 retrieval indices from the ICD-10-CM sample. OWNER: Person A.

Usage:
    python -m scripts.build_indices            # 200-row sample into both indices
    python -m scripts.build_indices --limit 500
    python -m scripts.build_indices --bm25-only

Reads `data/icd10/icd10cm_2026/icd10cm-codes-2026.txt` and writes the indices
under `data/indices/` (override with the CLINIQ_INDEX_DIR env var).
