---
## Detailed Verification
### Level 1: Artifact Existence
All 9 required files exist and have substantive implementations (124-414 lines each).
### Level 2: Substantive Implementation
**known_genes.py:**
- OMIM_USHER_GENES: frozenset with 10 genes (MYO7A, USH1C, CDH23, etc.)
- SYSCILIA_SCGS_V2_CORE: frozenset with 28 genes (IFT88, BBS1, CEP290, etc.)
- compile_known_genes(): Returns pl.DataFrame with 38 rows (10 + 28)
- load_known_genes_to_duckdb(): Persists to known_cilia_genes table
**integration.py:**
- join_evidence_layers(): LEFT JOIN gene_universe with 6 evidence tables
- compute_composite_scores(): NULL-preserving weighted average using COALESCE
- Formula: composite_score = weighted_sum / available_weight WHERE available_weight > 0 ELSE NULL
- Quality flags: sufficient (>=4), moderate (>=2), sparse (>=1), no_evidence (0)
**quality_control.py:**
- compute_missing_data_rates(): SQL aggregation with AVG(CASE WHEN col IS NULL)
- Thresholds: >50% warning, >80% error
- compute_distribution_stats(): numpy mean/median/std/min/max per layer
- Anomaly detection: std < 0.01 (no variation), min < 0 or max > 1 (out of range)
- detect_outliers(): scipy.stats.median_abs_deviation with 3 MAD threshold
**validation.py:**
- validate_known_gene_ranking(): PERCENT_RANK() window function over composite_score
- Creates temp table _known_genes, INNER JOIN on gene_symbol
- Validation logic: median_percentile >= 0.75 (top quartile)
- generate_validation_report(): Human-readable text with top 20 known genes
**score_cmd.py:**
- 5-step pipeline: load known genes → compute scores → persist → QC → validation
- Checkpoint-restart: checks store.has_checkpoint('scored_genes'), skips if exists unless --force
- Options: --force, --skip-qc, --skip-validation
- Displays comprehensive summary with quality flag distribution
**test_scoring.py (7 unit tests):**
1. test_compile_known_genes_returns_expected_structure: >= 38 genes, MYO7A/IFT88 present
2. test_compile_known_genes_no_duplicates_within_source: no duplicates per source
3. test_scoring_weights_validate_sum_defaults: default weights pass
4. test_scoring_weights_validate_sum_custom_valid: custom weights summing to 1.0 pass
5. test_scoring_weights_validate_sum_invalid: weights summing to 1.35 raise ValueError
6. test_scoring_weights_validate_sum_close_to_one: 0.999999 passes, 0.99 fails
7. test_null_preservation_in_composite: gene with 0 evidence gets NULL score, not 0
**test_scoring_integration.py (3 integration tests):**
1. test_scoring_pipeline_end_to_end: 20 synthetic genes, known genes rank in top 5
2. test_qc_detects_missing_data: 95% NULL triggers error, 60% triggers warning
3. test_validation_passes_with_known_genes_ranked_highly: validation_passed=True
### Level 3: Wiring Verification
**Integration module wired to config:**
- `from usher_pipeline.config.schema import ScoringWeights` in integration.py
- compute_composite_scores() takes `weights: ScoringWeights` parameter
- Calls `weights.validate_sum()` before scoring
**Quality control wired to DuckDB:**
- All 4 QC functions use `store.conn.execute()` to query scored_genes table
- SQL queries verified: AVG(CASE WHEN ... IS NULL), SELECT col FROM scored_genes WHERE col IS NOT NULL
**Validation wired to known genes:**
- `from usher_pipeline.scoring.known_genes import compile_known_genes` in validation.py
- validate_known_gene_ranking() calls compile_known_genes()
- Creates temp table, performs INNER JOIN with scored_genes
**CLI wired to scoring module:**
- `from usher_pipeline.scoring import` 6 functions in score_cmd.py
- cli/main.py imports score command: `from usher_pipeline.cli.score_cmd import score`
- Registered: `cli.add_command(score)` at line 103
**Tests wired to scoring module:**
- test_scoring.py imports compile_known_genes, compute_composite_scores, ScoringWeights
- test_scoring_integration.py creates synthetic PipelineStore, runs full pipeline
- All imports verified, no orphaned code
### Commit Verification

Phase 04 goal fully achieved. The scoring system:
1. Compiles 38 known cilia/Usher genes as positive controls
2. Integrates 6 evidence layers with configurable weights (sum to 1.0)
3. Preserves NULL semantics (missing evidence ≠ zero evidence)
4. Validates known genes rank highly (top quartile threshold)
5. Includes comprehensive QC checks (missing data, distributions, outliers)
6. Provides CLI interface with checkpoint-restart
7. Has 10 tests (7 unit + 3 integration) covering all functionality
