Error	Cause	Solution
Secret Not Found	Missing GitHub secret	Add OPENAI_API_KEY to repository secrets
Rate Limit in CI	Too many API calls	Use mocks for unit tests, limit integration tests
Timeout	Slow tests	Add timeout markers, parallelize tests
Import Error	Missing dev dependencies	Ensure `.[dev]` extras installed
