🟢coldstate_search(query, collection, index_id, limit, offset)

Search a ColdState index by collection name or index ID. Returns ranked results with Ψ scores and state classification (CRYSTALLINE/FLUID/REACTIVE/DECOHERENT). Provide exactly one of `collection` or `index_id`.

🟢coldstate_browse_documents(index_id, limit, offset)

  "$schema": "http://json-schema.org/draft-07/schema#"
}
🟢coldstate_related(id, limit)
