The Embedding Model Invalidation Trap: Why Swapping Models Destroys RAG
Originally published by the **Logic42 Sovereign Engineering Practice* at https://logic42.ai/articles/embedding-space-invalidation-trap-vector-migration.* The embedding model invalidation trap is a silent data corruption failure where engineering teams upgrade embedding models at the application layer without re-indexing historical vector databases. Because different embedding models project semantic representations into mathematically orthogonal vector spaces, calculating cosine distance betwee…
