"""Scan BacDive and write strain phenotype labels to data/bacdive_phenotypes.parquet.

Uses the v2 public API (no auth). Discovers strain IDs by batch-scanning the
integer ID range — missing IDs are silently dropped server-side, so the scan
is complete in one pass over [start, end].

Usage:
    # Phase 1 smoke test — scan the first ~5K IDs (returns ~3-4K real records)
    uv run python scripts/01_fetch_bacdive.py --end 5000

    # Full BacDive (~150K live records, ~30 min wall time)
    uv run python scripts/01_fetch_bacdive.py --end 200000
