`fetch_protein_coding_genes()` queries mygene for human protein-coding genes, validates count in 19k-22k range, returns sorted ENSG IDs +2. **Batch ID mapping** - `GeneMapper` converts Ensembl IDs to HGNC symbols and UniProt Swiss-Prot accessions via mygene batch queries with edge case handling (notfound, missing keys, nested structures, uniprot lists) +3. **Validation gates** - `MappingValidator` enforces configurable success rate thresholds with pass/warn/fail logic and produces unmapped gene reports for manual review +4. **Comprehensive testing** - 15 tests with mocked mygene responses covering successful mapping, unmapped genes, uniprot lists, batching, validation thresholds, and universe validation + +## Task Commits + +Each task was committed atomically: + +1. **Task 2: Create mapping validation gates with tests** -
