 # Pre-Release Validation Checklist
 
-This checklist ensures SDK releases meet quality standards. **Complete ALL items before publishing to PyPI.**
+The authoritative release design is documented in
+[`docs/RELEASE_PROCESS.md`](../docs/RELEASE_PROCESS.md). Complete every gate
+below before publishing a non-prerelease GitHub Release.
 
-## Automated Checks (Run Script)
+## Automated Gate
 
-```bash
-./scripts/pre-release-validation.sh
-```
-
-This script runs all automated validations and reports pass/fail status.
-

-
-## What Would Have Caught the v1.4.1 Bug?
-
-The historical timeout bug (reported by idan@comity.ai) would have been caught by:
-
-1. ✅ **Integration Tests** (`tests/integration/test_historical_endpoints.py`)
-   - `test_7_day_query_uses_past_week_endpoint` - Would fail (67s timeout)
-   - `test_365_day_query_uses_past_year_endpoint` - Would fail (30s timeout)
-
-2. ✅ **Performance Baselines** (`TestHistoricalPerformanceBaselines`)
-   - All tests would fail with timeouts
-
-3. ✅ **Pre-Release Script** (`scripts/pre-release-validation.sh`)
-   - Integration tests would fail
-   - Script would prevent release
-
-## Automation Script
-
-The `pre-release-validation.sh` script automates items 1-7:
+Run from a clean checkout of the release commit:
 
 ```bash
-# Run full validation
-./scripts/pre-release-validation.sh
-
-# Run with verbose output
-./scripts/pre-release-validation.sh --verbose
-
-# Skip slow tests (for quick checks)
-./scripts/pre-release-validation.sh --skip-slow
+python -m pip install --upgrade pip
+python -m pip install -e '.[dev]' build pip-audit
+ruff check oilpriceapi/
+mypy oilpriceapi/ --ignore-missing-imports
+pytest tests/ --ignore=tests/integration --ignore=tests/contract -m 'not slow'
+python scripts/validate_storefront_claims.py
+python scripts/generate_snippet_manifest.py --source-commit "$(git rev-parse HEAD)" --output artifacts/snippets/oilpriceapi-python-snippets-v1.json
+python -m build
+./scripts/clean-wheel-smoke.sh
+pip-audit
 ```
 
-**Exit Codes:**
-- `0` - All checks passed, ready to release
-- `1` - One or more checks failed, DO NOT release
-
-## Emergency Release Procedure
+The hosted Python 3.8-3.12 matrix, keyless and keyed live tests, canonical
+production snippets, and `Scheduled SDK Synthetic` must all be green at the
+same release commit. The repository test gate enforces at least 50% aggregate
+coverage; increases to that threshold require a reviewed test-coverage change.
 
-If critical bug requires immediate release:
-
-1. Run minimum validation:
-   ```bash
-   pytest tests/unit -v --tb=short
-   pytest tests/integration/test_historical_endpoints.py -v
-   ```
-
-2. Verify the specific fix works
-
-3. Document in CHANGELOG as emergency release
-
-4. **Still run full validation after emergency release**
-
-## Failed Validation - What to Do
-
-### Tests Failed
-1. Fix failing tests
-2. Re-run full validation
-3. Update CHANGELOG if fixes required code changes
-
-### Performance Regression
-1. Investigate using profiling
-2. Fix performance issue
-3. Re-establish baseline
-
-### Documentation Missing
-1. Update documentation
-2. Add code examples
-3. Test examples actually work
-
-### Build Failed
-1. Check `pyproject.toml` for errors
-2. Verify all files included in manifest
-3. Test clean build: `rm -rf dist/ && python -m build`
-
-## Version History
-
-| Version | Date | Validator | Result | Notes |
-|---------|------|-----------|--------|-------|
-| v1.4.2 | 2025-12-16 | Manual | ✅ Pass | Fixed historical timeout bug |
-| v1.4.1 | 2025-12-15 | None | ❌ Fail | Historical timeout bug shipped |
-
-*Note: v1.4.1 did not use this checklist, which is why the bug reached production.*

+## Release Metadata
 
-## Contact
+- `pyproject.toml` and `oilpriceapi/version.py` contain the same version.
+- `CHANGELOG.md` has one release section for that version with customer-visible
+  behavior and recovery guidance.
+- The version is absent from PyPI and from existing GitHub releases.
+- The release tag is exactly `v<package-version>`.
+- The worktree is clean and the tag resolves to the reviewed main commit.

-- GitHub Issues: https://github.com/OilpriceAPI/python-sdk/issues
-- Email: support@oilpriceapi.com
+## Publication And Recovery
 
-## Related Issues
+Publish through a non-prerelease GitHub Release only. The `Publish to PyPI`
+workflow verifies the tag, repeats the tests and dependency audit, builds and
+installs the wheel in a clean environment, attaches the snippet manifest, and
+uses PyPI trusted publishing. Do not upload with Twine or a local API token.

+PyPI artifacts are immutable. If a production defect appears, stop promotion,
+yank the affected version, add a failing regression test, and publish a new
+patch version through the same gate.
