## Summary - update all workspace `vitest` declarations to `4.1.9` - update `@vitest/browser-playwright` and `@vitest/browser-webdriverio` declarations to `4.1.9` - refresh `pnpm-lock.yaml` so no `vitest`/`@vitest/browser` versions below `4.1.9` remain ## Validation - `sfw pnpm install` - `pnpm format:check` - `pnpm lint` - `pnpm build` - targeted audit check: no `vitest` or `@vitest/browser` advisories remain - `pnpm --filter create-langgraph test` - `pnpm --filter @langchain/react test` - `pnpm --filter @langchain/svelte test` - `pnpm --filter @langchain/vue test` - `pnpm --filter @langchain/angular test` - `pnpm --filter @langchain/langgraph test` ## Notes - `pnpm --filter @langchain/langgraph test:browser` did not run locally because Playwright Chromium for the updated provider was not installed on this machine; Vitest exited before running tests with Playwright's `pnpm exec playwright install` message. - The SDK Vitest suites passed but printed Vitest's post-success close-timeout warning.

Implementation of a LangGraph.js CheckpointSaver that uses a SQLite DB.
Usage
import { SqliteSaver } from "@langchain/langgraph-checkpoint-sqlite";
const writeConfig = {
configurable: {
thread_id: "1",
checkpoint_ns: ""
}
};
const readConfig = {
configurable: {
thread_id: "1"
}
};
const checkpointer = SqliteSaver.fromConnString(":memory:");
const checkpoint = {
v: 1,
