🧪 Tests

Note on testing: integration tests are limited—many providers require real accounts that we don’t currently have, so only transformers with publicly available sandboxes were exercised. Community help with additional live-account tests is welcome!

⚠️ Notes

• API is still preview; minor breaking changes may occur before v1.0.0
• CLI tool (milestone P1) is not included in this release
• Feedback and PRs are welcome!
