Scans every src/**/*.svelte.{spec,test}.ts file for vi.mock first-arg
strings, canonicalises each by stripping a trailing .js/.ts after
.svelte, groups by canonical id, and fails if any canonical id is
referenced under two or more distinct raw spellings.
Mirrors the shape of src/__meta__/no-async-mock-factories.test.ts:
source-text regex scan (no AST parser dependency), red/green self-test
fixtures inline, then one corpus assertion that the whole suite is
clean.
This is the in-suite defence-in-depth layer for the duplicate-id birpc
race named in ADR-012 / #553 and fixed upstream by vitest PR #10267.
Harder to disable than ESLint (cross-file invariant ESLint cannot
express anyway) and harder to scope around than a CI grep.

sv
Everything you need to build a Svelte project, powered by sv.
Creating a project
If you're seeing this, you've probably already done this step. Congrats!
# create a new project in the current directory
npx sv create
# create a new project in my-app
npx sv create my-app
Developing
Once you've created a project and installed dependencies with npm install (or pnpm install or yarn), start a development server:
npm run dev
# or start the server and open the app in a new browser tab
npm run dev -- --open
Building
To create a production version of your app:
npm run build
You can preview the production build with npm run preview.
To deploy your app, you may need to install an adapter for your target environment.
