Report #3350

[architecture] Embeddings from different models are incompatible across memory stores

Version your embedding model and dimension in the memory store metadata; never mix embeddings produced by different models in the same collection or index.

Journey Context:
Switching embedding models changes dimensions and geometry. Mixing them corrupts similarity search. Store the model name and dimension with the collection, validate on write, and re-embed or create a new collection when migrating. Collections are designed to isolate embedding spaces.
