pub fn default_embedder() -> Box<dyn Embedder>Expand description
The embedder the journal uses unless overridden. With the embed feature
(on by default) it loads the model2vec static model for true semantic
recall; if that can’t load — offline first run, download failure, or
TJ_EMBED=hash — it falls back to the dependency-free lexical
HashEmbedder so the journal never breaks.
