"""Generate a labeled sample batch covering all 12 verification test-case types.
For each ``case_type`` in ``src.verification.case_types.CASE_TABLE`` (1a
through 5b), generates a couple of samples via ``GeneratorContext`` directly
(bypassing ``DatasetGenerator`` since each case needs its own config
override), writes the rendered PNGs + metadata JSONs to
``output/verification_suite/``, and prints a verdict/reject_code summary
table.
Usage:
python scripts/generate_verification_suite.py [--per-case N]
