Computation Over Geometry: Meaning Identity Is Computed, Not Shipped in the Embeddings

- What happened
- Research shows semantic similarity detection requires joint computation between sentence pairs, not geometric properties of independent embeddings alone.
- Why it matters
- Matters for engineers building retrieval, RAG, and semantic search systems relying on frozen encoders or embedding-based reranking.
- Watch out
- Joint forward passes achieve 0.90-0.96 AUC but independent encodings plateau near 0.55-0.70; transfer learning and generalization remain unclear.
