"""Tests for all 15 benchmark dataset and scorer registrations.

These tests verify:
1. Each dataset class can be instantiated
2. Each dataset has correct dataset_id and dataset_name
3. Each scorer class can be constructed (with mock backend)
4. The CLI _build_dataset and _build_scorer factories work for all benchmarks
5. KNOWN_BENCHMARKS in config.py includes all 15 benchmarks
