-**Workarounds**:
+**Current Status**:
-- Manual testing (source builds) works consistently
+- **Stable testing**: Python 3.10 and 3.12 are required to pass (blocking jobs)

+- **Preview testing**: Python 3.13 runs as non-blocking to monitor ecosystem readiness
-- Some runs may succeed if compatible `chroma-hnswlib` wheels are available on PyPI
+- **Compilation issues**: Python 3.13 may still fail due to `chroma-hnswlib` but won't block releases
+- **Manual testing**: Source builds now use the same dependency transformation as nightly builds for testing parity
