# Phase 01: Data Infrastructure Verification Report
|
||
|
||
**Phase Goal:** Establish reproducible data foundation and gene ID mapping utilities
|
||
**Verified:** 2026-02-11T08:47:54Z
|
||
**Status:** passed
|
||
**Re-verification:** No - initial verification
|
||
|
||
## 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 |
|
||
| INFRA-07: Checkpoint-restart with DuckDB/Parquet persistence | ✓ SATISFIED | PipelineStore.has_checkpoint() detects existing tables, CLI setup skips re-fetch if checkpoint exists, export_parquet() for downstream compatibility |
|

||
### 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
|
||
|
||

|
||
- 01-02: Gene ID mapping and validation (15 tests pass)
|
||
- 01-03: DuckDB persistence and provenance tracking (12 tests pass, 1 skipped)
|
||
