2// Semantic runtime: makes local embeddings work after a normal install.

4// '@huggingface/transformers' is deliberately NOT a dependency of the npm

5// package — it would turn a 28MB install into a ~250MB one and slow the

6// `npx memwarden audit` funnel to a crawl. Instead `memwarden up` installs

7// it ONCE into <dataDir>/runtime (npm --prefix), and the embedding loader

8// falls back to that location when the bare specifier doesn't resolve.

9// Everything stays honest: if neither resolves, the daemon says

10// "lexical-only" instead of silently degrading.
