Keeping `kind: "select"` for a namespaced definition was a silent downgrade hazard: released readers drop unknown fields and resolve a select source at the root, so a rolled-back worker could refresh a view from a same-name root table and certify the wrong rows. Root definitions keep the `select` form byte-for-byte; a namespaced source is stored as `namespaced_select`, which older readers route to their existing unrecognized-kind refusal. The reader also refuses a kind that disagrees with its namespace, since no correct writer produces one. The Python and Node definition parsers learn the new kind alongside the Rust core, so every same-version reader agrees.

Usage
Basic Example
import * as lancedb from "@lancedb/lancedb";
const db = await lancedb.connect("data/sample-lancedb");
const table = await db.createTable("my_table", [
{ id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
{ id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
]);
const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
console.log(results);
