Here's what the tests verify:\n\n## Test Coverage Summary\n\n### 1. **Registry Matching Tests**\n- `test_all_asset_types_have_rubrics()`: Verifies every asset_type in the registry has a corresponding rubric\n- `test_get_rubric_for_valid_asset_type()`: Tests successful rubric retrieval\n- `test_get_rubric_for_invalid_asset_type()`: Tests error handling for missing rubrics\n\n### 2. **Threshold Scoring Tests**\n- `test_passing_score()`: Tests scores >= 0.70 result in 'pass'\n- `test_auto_reject_score()`: Tests scores < 0.40 result in 'auto-reject'\n- `test_review_needed_score()`: Tests scores 0.40-0.69 result in 'needs_review'\n- `test_edge_cases()`: Tests boundary conditions (exactly 0.70, 0.40, etc.)\n\n### 3. **Consensus Computation Tests**\n- `test_consensus_with_two_graders()`: Tests averaging with 2 graders\n- `test_consensus_with_three_graders()`: Tests averaging with 3 graders\n- `test_consensus_with_single_grader()`: Tests single grader scenario\n- `test_consensus_with_missing_dimensions()`: Tests error handling for incomplete scores\n\n### 4. **Dimension Weighting Tests**\n- `test_api_route_security_weight_higher()`: Specifically tests that security has higher weight for API routes\n- `test_dimension_weights()`: Tests weight assignment and validation\n- `test_consensus_with_zero_weights()`: Tests handling of zero-weighted dimensions\n\n### 5. **Integration and Validation Tests**\n- `test_full_grading_workflow()`: Tests complete end-to-end grading process\n- `test_all_rubrics_are_valid()`: Validates structure and weight sums for all rubrics\n- `test_high_variance_grading()`: Tests scenarios with disagreeing graders\n\n### 6. **Error Handling Tests**\n- `test_empty_grader_scores()`: Tests empty input handling\n- `test_mismatched_dimensions()`: Tests dimension mismatch scenarios\n- `test_invalid_weight_sum()`: Tests invalid weight configurations\n\nThe tests are designed to work with the actual implementation in `foundry_grading_v4.py` and will verify that the v4 grading system works correctly according to the specifications. They use pytest fixtures and comprehensive assertions to ensure robust validation of the grading rubric system."
