"""
Unit tests for --force flag, --modules selection, --analyzed mode, and --rerun mode.

Tests that:
1. --force bypasses both bulk and per-file dedup checks (feature-extraction AND decompile paths)
2. --modules does NOT implicitly enable force (force must be explicit)
3. Default behavior (no --force) preserves dedup checks
4. --analyzed queries basic_properties and handles decompile dedup filtering
5. --rerun queries disassembled table directly (with --analyzed --decompile)
6. Decompile per-file is_in_code_db respects --force flag
7. YARA scanning skips already-scanned samples by default, rescans all with --force
