"""Qdrant collection audit + cleanup for test_col_* artifacts.

T15 (G14 FIX) - Qdrant accumulates test_col_* collections from integration
tests that forget to clean up. This script audits and cleans them.

Usage:
    # Audit only (safe - no changes):
    python scripts/ops/qdrant_audit.py
    python scripts/ops/qdrant_audit.py --audit-only

    # Audit + cleanup (drops test_col_*):
    python scripts/ops/qdrant_audit.py --cleanup

    # Custom Qdrant URL:
    python scripts/ops/qdrant_audit.py --url http://qdrant.example:6333 --cleanup

    # CI gate mode (exit 1 if any test_col_* found):
    python scripts/ops/qdrant_audit.py --check

Cron suggestion (netcup):
    # Daily audit, notify if anything leaked:
    0 6 * * * python3 /root/scripts/qdrant_audit.py --audit-only | \\
        curl -s --data-binary @- http://localhost:9080/rmi-info || true
