Local knowledge & RAG

Install, search, and govern on-device knowledge.

Install documents

Chunking (sentence-boundary, with overlap) and indexing happen at install time.

await lybo.installKnowledge({
  doc_id: "manual", title: "Pump Manual",
  body: "The seal on pump unit seven…",
  scope: "app",              // or a pack id / "org" / "user"
  expires_ms: null,           // expired chunks never surface
});

Enable hybrid search (optional, recommended)
Blends BM25 keyword scoring with embedding cosine similarity; also upgrades intent routing to handle paraphrases.
```
lybo studio --semantic   # or rt.enable_semantic_routing(None)
```
3
Query through the retrieval pattern
Answers are grounded in retrieved chunks only, carry source titles, and say “no local information” rather than inventing content.

Scopes partition knowledge (per pack, org, user) and are enforced at query time.
Compression trims each hit to fit small context windows before prompting.
Knowledge packs version and update content over the air with review/expiry dates.
