Summary#
Performance-oriented internals often flatten or pack data into forms that downstream hooks cannot use correctly. Keep the optimized representation internal, and restore the consumer-facing structure right before callbacks, previews, or plugin APIs run. Preserve the simple fast path and add any model-specific metadata the consumer needs instead of forcing every consumer to understand internal packing.
Problem#
An internal optimization changes tensor or tree shape, but downstream preview, logging, or extension code still expects the higher-level semantic structure and breaks or becomes unusable.
Solution#
Add an explicit boundary adapter that converts packed internal data back into the public semantic form before invoking external consumers, while leaving already-simple cases unchanged and supplying missing consumer-specific factors or metadata.
Failure Modes#
- Leaking internal packed shapes into public callbacks and making every consumer reimplement unpacking
- Applying the conversion on every case and turning a compatibility fix into a hot-path regression
- Restoring the outer structure but forgetting model- or format-specific metadata needed by preview/render code
