+## Goal Achievement
+
+### Observable Truths
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | Pipeline uses Ensembl gene IDs as primary keys throughout with validated mapping to HGNC symbols and UniProt accessions | ✓ VERIFIED | GeneMapper.map_ensembl_ids() returns MappingResult with ensembl_id, hgnc_symbol, uniprot_accession. CLI setup command saves gene_universe table with all three columns. |
+| 2 | Configuration system loads YAML parameters with Pydantic validation and rejects invalid configs | ✓ VERIFIED | load_config() uses Pydantic v2 PipelineConfig with field validators (ensembl_release >= 100). Tests verify ValidationError on invalid input. |
+| 3 | API clients retrieve data from external sources with rate limiting, retry logic, and persistent disk caching | ✓ VERIFIED | CachedAPIClient base class uses requests_cache (SQLite backend), tenacity retry (429/5xx), rate limiting (configurable req/sec). Tests verify cache hits and rate limit behavior. |
+| 4 | DuckDB database stores intermediate results enabling restart-from-checkpoint without re-downloading | ✓ VERIFIED | PipelineStore.has_checkpoint() detects existing tables. CLI setup command checks checkpoint and skips re-fetch. Integration tests verify checkpoint-restart flow. |
+| 5 | Every pipeline output includes provenance metadata: pipeline version, data source versions, timestamps, config hash | ✓ VERIFIED | ProvenanceTracker captures pipeline_version, data_source_versions, config_hash, created_at, and processing_steps. CLI setup command saves provenance sidecar JSON. |
+
+**Score:** 5/5 truths verified

+### Requirements Coverage
+
+| Requirement | Status | Supporting Evidence |
+|-------------|--------|---------------------|
+| INFRA-01: Gene universe defined as protein-coding genes from Ensembl | ✓ SATISFIED | fetch_protein_coding_genes() in universe.py queries mygene with "type_of_gene:protein-coding", validates count 19k-22k |
+| INFRA-02: Ensembl gene IDs as primary keys with HGNC/UniProt mapping | ✓ SATISFIED | GeneMapper.map_ensembl_ids() produces MappingResult with all three IDs, gene_universe table has ensembl_id, hgnc_symbol, uniprot_accession columns |
+| INFRA-03: Validation gates report mapping success rates | ✓ SATISFIED | MappingValidator.validate() checks min_success_rate (default 90%), MappingReport tracks success_rate_hgnc and success_rate_uniprot, saves unmapped report |
+| INFRA-04: API clients with rate limiting, retry, caching | ✓ SATISFIED | CachedAPIClient has tenacity retry (429/5xx/network errors, exponential backoff 2-60s), requests_cache SQLite persistent cache, rate limiting (configurable req/sec) |
+| INFRA-05: YAML config with Pydantic validation | ✓ SATISFIED | PipelineConfig uses Pydantic v2 with field validators (ensembl_release >= 100), default.yaml with all parameters, load_config() rejects invalid configs |
+| INFRA-06: Provenance metadata in all outputs | ✓ SATISFIED | ProvenanceTracker captures pipeline_version, data_source_versions, config_hash, timestamps, processing_steps; save_sidecar() creates .provenance.json; CLI setup saves provenance |

+No anti-patterns detected. Scanned files:
+- src/usher_pipeline/cli/main.py
+- src/usher_pipeline/cli/setup_cmd.py
+- tests/test_integration.py
+- src/usher_pipeline/config/schema.py

+- src/usher_pipeline/gene_mapping/mapper.py
+- src/usher_pipeline/persistence/duckdb_store.py
+- src/usher_pipeline/persistence/provenance.py
+
+Checks performed:
+- No TODO/FIXME/PLACEHOLDER/HACK comments
+- No empty implementations (return null/{},[])
+- No console.log-only functions
+- All functions have substantive implementations
+
+### Human Verification Required
+
+#### 1. Full CLI Execution Test
+
+**Test:** Install package in fresh virtual environment and run full setup flow
+```bash
+python3 -m venv test_venv
+source test_venv/bin/activate
+pip install -e ".[dev]"
+usher-pipeline --help
+usher-pipeline info --config config/default.yaml
+usher-pipeline setup --config config/default.yaml
+```
+
+**Expected:** 
+- usher-pipeline command available after install
+- info command displays version, config hash, data source versions
+- setup command fetches ~20,000 protein-coding genes from mygene
+- Mapping success rate >= 90% for HGNC symbols
+- gene_universe table created in DuckDB with 3 columns (ensembl_id, hgnc_symbol, uniprot_accession)
+- Provenance sidecar created at data/setup.provenance.json
+- Second run detects checkpoint and skips re-fetch
+
+**Why human:** Full integration with real external APIs (mygene), network latency, actual API responses may vary from mocks
+
+#### 2. Config Validation Behavior
+
+**Test:** Create invalid config files and verify rejection
+```bash
+# Test 1: Invalid ensembl release
+echo "ensembl_release: 50" > test_bad.yaml
+usher-pipeline info --config test_bad.yaml  # Should fail with ValidationError
+
+# Test 2: Missing required field
+echo "data_dir: /tmp/data" > test_incomplete.yaml
+usher-pipeline info --config test_incomplete.yaml  # Should fail
+```
+
+**Expected:** Clear ValidationError messages explaining what's wrong
+
+**Why human:** Error message clarity and user experience assessment
+
+#### 3. Checkpoint-Restart Robustness
+
+**Test:** Interrupt setup mid-execution, verify restart works
+```bash
+usher-pipeline setup &
+PID=$!
+sleep 5  # Let it start fetching
+kill $PID  # Interrupt
+usher-pipeline setup  # Should resume or skip completed steps
+```
+
+**Expected:** Graceful handling of interruption, checkpoint detection on restart
+
+**Why human:** Tests real-world failure scenarios and resource cleanup
+
+#### 4. Test Suite Completeness
+
+**Test:** Run full test suite
+```bash
+pytest tests/ -v --cov=usher_pipeline --cov-report=term-missing
+```
+
+**Expected:** 
+- 49 tests pass, 1 skipped (pandas)
+- Coverage >= 80% for core modules
+- No import errors or fixture issues
+
+**Why human:** Verify test environment setup works correctly
+
