## Summary
- **SDK (`dev` & `dev --once`)**: After app registration, the CLI now
obtains an `APPLICATION_ACCESS` token via `client_credentials` grant
using the app's own `clientId`/`clientSecret`, and uses that token for
CoreApiClient schema introspection — instead of the user's
`config.accessToken` which returns the full unscoped schema.
- **Config**: `oauthClientSecret` is now persisted alongside
`oauthClientId` in `~/.twenty/config.json` when creating a new app
registration, so subsequent `dev`/`dev --once` runs can obtain fresh app
tokens without re-registration.
- **CI action**: `spawn-twenty-app-dev-test` now outputs a proper
`API_KEY` JWT (signed with the seeded dev workspace secret) instead of
the previous hardcoded `ACCESS` token — giving consumers a real API key
rather than a user session token.
## Motivation
When developing Twenty apps, `yarn twenty dev` was using the CLI user's
OAuth token for GraphQL schema introspection during CoreApiClient
generation. This token (type `ACCESS`) has no `applicationId` claim, so
the server returns the **full workspace schema** — including all objects
— rather than the scoped schema the app should see at runtime (filtered
by `applicationId`).
This caused a discrepancy: the generated CoreApiClient contained fields
the app couldn't actually query at runtime with its `APPLICATION_ACCESS`
token.
By switching to `client_credentials` grant, the SDK now introspects with
the same token type the app will use in production, ensuring the
generated client accurately reflects the app's runtime capabilities.
## Summary
- Move 4 test fixture apps from `twenty-sdk/src/cli/__tests__/apps/` to
`twenty-apps/fixtures/` with meaningful names (`rich-app` →
`postcard-app`, `root-app` → `minimal-app`)
- Replace all `from '@/sdk'` imports with `from 'twenty-sdk'` so fixture
apps are proper, portable twenty-sdk apps
- Remove the fragile `"@/*": ["../../../../../src/*"]` tsconfig hack and
replace with standard `"src/*": ["./src/*"]` paths
- Create a centralized `fixture-paths.ts` utility in twenty-sdk tests
for clean app path resolution
## Why
The fixture apps were deeply nested in twenty-sdk's test directory and
tightly coupled to its internal source layout via a tsconfig path alias
hack. This made them:
- Impossible to reuse outside of SDK CLI tests (e.g., for server-side
dev seeding with `DevSeederService`)
- Fragile — moving any twenty-sdk source file could break the path alias
- Poorly discoverable — buried 5 directories deep in test infrastructure
Moving them to `twenty-apps/fixtures/` makes them first-class portable
apps that can be imported by `twenty-server` for seeding, used in E2E
testing, and serve as canonical examples alongside `hello-world`.
## Test plan
- [x] All 8 twenty-sdk integration tests pass (3 suites: postcard-app,
minimal-app, invalid-app)
- [x] Prettier formatting verified on all changed files
- [ ] CI should confirm E2E tests also pass (these require a running
server)
