# Plan: Comprehensive Validation from Clean Slate

**ADR ID**: 0031
**Status**: In Progress
**Created**: 2025-01-22
**Last Updated**: 2025-01-22

## Objective

Validate from clean slate that gapless-crypto-clickhouse repository is working correctly across all dimensions, then fix all CRITICAL and HIGH priority issues found.

**Success Criteria**:

- All code compiles and imports successfully
- Test suite passes (unit tests minimum)
- Documentation claims match implementation (versions, counts, API surface)
- Example code executes without errors
- All CRITICAL issues fixed before release

## Background

### Problem

6-agent parallel audit (2025-01-22) identified critical discrepancies:

**CRITICAL Issues**:

1. Version mismatch: `__init__.py` shows 1.0.0 but `pyproject.toml` shows 8.0.0
2. Timeframe constants incomplete: Docs claim 16, implementation has 13 (missing 3d, 1w, 1mo)
3. Mypy config broken: References `gapless_crypto_data` instead of `gapless_crypto_clickhouse`

**HIGH Issues**: 4. Symbol count stale: Docs say "400+" but actual is 713 5. CLI commands in API-only package documentation 6. Non-existent API methods documented 7. Stale version references (v3.x, v4.x in v8.0.0 codebase)

### Context

- Package currently at v8.0.0 (released 2025-11-22)
- ADR-0029 completed package name alignment
- ADR-0030 deferred comprehensive doc cleanup
- Recent fix (2025-01-22) corrected timeframe count 13→16 in docs
- Need to verify if 16 timeframes actually implemented or just documented

### Constraints

- **No breaking changes**: Fixes must maintain API compatibility
- **Evidence-based**: All claims must be verified against implementation
- **Automated validation**: Use existing validation scripts where possible
- **Python 3.14 compatibility**: May encounter pandas build issues in tests

## Plan

### Phase 1: Automated Foundation Validation (10 min)

**1.1 Environment Health**

```bash
python --version  # Verify 3.12+
uv --version
uv sync --dev
```

**1.2 Static Analysis**

```bash
uv run ruff format --check .
uv run ruff check .
uv run mypy src/  # Expected to fail due to wrong package name
```

**1.3 Package Import**

```bash
# Test import and discover version mismatch
uv run python -c "import gapless_crypto_clickhouse as gcd; print(f'Version: {gcd.__version__}')"
```

**1.4 Validation Scripts**

```bash
uv run python validate_examples.py
uv run python verify_cross_references.py
```

**Expected Outcomes**:

- ✅ Ruff passes
- ❌ Mypy fails (CRITICAL #3)
- ⚠️ Version shows 1.0.0 (CRITICAL #1)
- ✅ Examples validate (ADR-0029 cleanup)
- ✅ Cross-refs validate (files created)

### Phase 2: Test Suite Execution (15 min)

**2.1 Unit Tests**

```bash
uv run pytest -m unit -v --tb=short
```

**2.2 Integration Tests** (if ClickHouse available)

```bash
docker-compose ps  # Check services
uv run pytest -m integration -v --tb=short
```

**2.3 Full Suite with Coverage**

```bash
uv run pytest --cov=src/gapless_crypto_clickhouse --cov-report=term --cov-report=html -v
```

**2.4 Example Compilation**

```bash
for file in examples/*.py; do python -m py_compile "$file"; done
```

**Expected Outcomes**:

- ✅ Unit tests pass
- ⚠️ Integration tests may skip (service dependency)
- ⚠️ Some tests may fail (Python 3.14 pandas compatibility)
- ✅ Examples compile

### Phase 3: Ground Truth Verification (20 min)

**3.1 Version Audit**

```bash
grep '^version = ' pyproject.toml
grep '"version"' package.json
grep '^__version__ = ' src/gapless_crypto_clickhouse/__init__.py
uv run python -c "import gapless_crypto_clickhouse; print(gapless_crypto_clickhouse.__version__)"
```

**Expected**: pyproject.toml/package.json show 8.0.0, **init**.py shows 1.0.0 ❌

**3.2 Timeframe Count Audit**

```bash
uv run python -c "
from gapless_crypto_clickhouse import get_supported_timeframes
from gapless_crypto_clickhouse.utils.timeframe_constants import TIMEFRAME_TO_MINUTES

tf = get_supported_timeframes()
print(f'API returns: {len(tf)} timeframes')
print(f'Constants define: {len(TIMEFRAME_TO_MINUTES)} mappings')
print(f'Exotic timeframes:')
for exotic in ['3d', '1w', '1mo']:
    print(f'  {exotic}: {exotic in TIMEFRAME_TO_MINUTES}')
"
```

**Expected**: API may return 16, but constants only have 13 ❌

**3.3 Symbol Count Audit**

```bash
uv run python -c "
from gapless_crypto_clickhouse import get_supported_symbols
symbols = get_supported_symbols()
print(f'Actual count: {len(symbols)}')
"

grep -n "400\|713" CLAUDE.md README.md
```

**Expected**: Implementation has 713, some docs say "400+" ⚠️

**3.4 Package Name Audit**

```bash
grep -A 1 "module = " pyproject.toml | grep "gapless_crypto_data"
```

**Expected**: 3 mypy overrides with wrong name ❌

**3.5 API Surface Discovery**

```bash
uv run python -c "
import gapless_crypto_clickhouse as gcd
api = gcd.__probe__.discover_api()
import json
with open('api_surface.json', 'w') as f:
    json.dump(api, f, indent=2)
print('API surface saved')
"
```

**Use for**: Validating documented methods exist

### Phase 4: Fix Critical Issues (15 min)

**Fix #1: Version Mismatch**

```python
# Edit src/gapless_crypto_clickhouse/__init__.py line 84
__version__ = "8.0.0"  # Was: "1.0.0"
```

**Fix #2: Timeframe Constants**

Decision point: Check if collector actually implements 16 timeframes

- If yes: Add 3d, 1w, 1mo to timeframe_constants.py
- If no: Revert docs back to 13 timeframes

```python
# If implementing 16, add to timeframe_constants.py:
TIMEFRAME_TO_MINUTES = {
    # ... existing 13 ...
    "3d": 4320,    # 3 days * 24 * 60
    "1w": 10080,   # 7 days * 24 * 60
    "1mo": 43200,  # 30 days * 24 * 60 (approximate)
}
```

**Fix #3: Mypy Config**

```bash
# Edit pyproject.toml lines 119, 124, 128
sed -i '' 's/gapless_crypto_data\./gapless_crypto_clickhouse./g' pyproject.toml
```

**Fix #4: Symbol Count**

```bash
# Update CLAUDE.md: 400+ → 713
sed -i '' 's/400+/713/g' CLAUDE.md
```

**Validation After Fixes**:

```bash
# Verify version
uv run python -c "import gapless_crypto_clickhouse; assert gapless_crypto_clickhouse.__version__ == '8.0.0'"

# Verify mypy works
uv run mypy src/

# Verify timeframes
uv run python -c "from gapless_crypto_clickhouse.utils.timeframe_constants import TIMEFRAME_TO_MINUTES; print(f'Timeframes: {len(TIMEFRAME_TO_MINUTES)}')"

# Run tests
uv run pytest -m unit -v
```

### Phase 5: Documentation & Release (10 min)

**5.1 Generate Validation Report**

Create `VALIDATION_REPORT.md` with:

- Executive summary
- Critical issues found and fixed
- Test results
- Coverage metrics
- Evidence artifacts

**5.2 Commit with Conventional Commits**

```bash
git add -A
git commit -m "fix(validation): resolve critical version and config issues

CRITICAL FIXES:
- Fix __init__.py version: 1.0.0 → 8.0.0 (align with pyproject.toml)
- Fix mypy config: gapless_crypto_data → gapless_crypto_clickhouse
- [Add/Fix] timeframe constants: [decision outcome]
- Update CLAUDE.md: symbol count 400+ → 713

VALIDATION:
- All code compiles and imports successfully
- Unit tests pass
- Documentation claims verified against implementation
- Examples execute without errors

Implements: ADR-0031
Closes: [issues if any]
"
```

**5.3 Release**

Use semantic-release skill (conventional commits → version bump → changelog → GitHub release):

```bash
# Push to trigger release workflow
git push origin main

# Release should be patch (8.0.1) unless breaking changes
# Wait for GitHub Actions to complete
```

## Context

### Discovered During Validation

**Implementation Check: Timeframes**

Checked `src/gapless_crypto_clickhouse/collectors/binance_public_data_collector.py:281-298`:

```python
available_timeframes = [
    "1s", "1m", "3m", "5m", "15m", "30m",
    "1h", "2h", "4h", "6h", "8h", "12h", "1d",
    "3d", "1w", "1mo"  # ← Exotic timeframes ARE implemented
]
```

**Verdict**: Implementation HAS 16 timeframes. Constants file incomplete (missing 3).

**Decision**: Add exotic timeframes to constants (Fix #2 confirmed).

### Test Infrastructure

- 31 test files covering unit/integration/e2e
- Markers: `unit` (fast), `integration` (ClickHouse), `e2e` (Playwright)
- Coverage target: 54% overall, 85%+ SDK entry points
- Known issue: Python 3.14 pandas compatibility (may skip some tests)

### Validation Scripts Available

- `validate_examples.py`: Syntax, imports, package names
- `verify_cross_references.py`: Markdown links
- `__probe__.discover_api()`: API surface mapping
