# Intoduction
Closes https://github.com/twentyhq/core-team-issues/issues/2289
In this PR all the clients becomes available under `twenty-sdk/clients`,
this is a breaking change but generated was too vague and thats still
the now or never best timing to do so
## CoreClient
The core client is now shipped with a default stub empty class for both
the schema and the client
Allowing its import, will still raises typescript errors when consumed
as generated but not generated
## MetadataClient
The metadata client is workspace agnostic, it's now generated and
commited in the repo. added a ci that prevents any schema desync due to
twenty-server additions
Same behavior than for the twenty-front generated graphql schema
## Summary
- The `createOneApplication` GraphQL mutation was removed from the
server during the application architecture refactor (#18432), but the
SDK CLI (`app:dev`, `app:build --sync`) still called it, causing
failures.
- Simplified the SDK to use `syncApplication` (which now internally
creates the `ApplicationEntity` via `ensureApplicationExists`) instead
of a separate create step.
- On first run (clean install), the orchestrator now runs an initial
sync before initializing the file uploader, so file uploads can proceed
(they require the `ApplicationEntity` to exist).
## Test plan
- [x] Typecheck passes for both `twenty-sdk` and `twenty-server`
- [x] `app:dev` tested locally with existing app (finds app, uploads,
syncs)
- [x] `app:dev` tested locally after `app:uninstall` (creates app via
sync, uploads, syncs)
- [x] SDK unit tests pass (23/26 files, 3 pre-existing failures
unrelated)

# Introduction
Adding integration test scaffold to the create twenty app and an example
to the hello world app
This PR also fixes all the sdk e2e tests in local
## `HELLO_WORLD`
Removed the legacy implem in the `twenty-apps` folder, replacing it by
an exhaustive app generation
## Next step
Will in another PR add workflows for CI testing
## Open question
- Should we still add vitest config and dep even if the user did not ask
for the integration test example ? -> currently we don't
- That's the perfect timing to identify if we're ok to handle seed
workspace authentication with the known api key
