# Limitations

- Seamless Interaction-derived media is non-commercial and is reconstructed from upstream rather than redistributed.
- Upstream archives or mirrors may become unavailable.
- Generated speech is useful for serialization and pipeline training checks but is not a substitute for diverse natural speech.
- OCR examples are generated and do not measure real-world OCR robustness.
- VLM/CLAP/WhisperX annotations can contain model errors even after structural validation.
- WhisperX timing is segment-level, not word-level.
- The minimal 12-step training test validates data/collator/backprop integration only; it is not evidence of compatibility with every production model.
- Agent review is not human review.
