## Add API client generation to SDK dev mode and refactor orchestrator
into step-based pipeline
### Why
The SDK dev mode lacked typed API client generation, forcing developers
to work without auto-generated GraphQL types when building applications.
Additionally, the orchestrator was a monolithic class that mixed watcher
management, token handling, and sync logic — making it difficult to
extend with new steps like client generation.
### How
- **Refactored the orchestrator** into a step-based pipeline with
dedicated classes: `CheckServer`, `EnsureValidTokens`,
`ResolveApplication`, `BuildManifest`, `UploadFiles`,
`GenerateApiClient`, `SyncApplication`, and `StartWatchers`. Each step
has typed input/output/status, managed by a new `OrchestratorState`
class.
- **Added `GenerateApiClientOrchestratorStep`** that detects
object/field schema changes and regenerates a typed GraphQL client (via
`@genql/cli`) into `node_modules/twenty-sdk/generated` for seamless
imports.
- **Replaced `checkApplicationExist`** with `findOneApplication` on both
server resolver and SDK API service, returning the entity data instead
of a boolean.
- **Added application token pair mutations**
(`generateApplicationToken`, `renewApplicationToken`) to the API
service, with the server now returning `ApplicationTokenPairDTO`
containing both access and refresh tokens.
- **Restructured the dev UI** into `dev/ui/components/` with dedicated
panel, section, and event log components.
- **Simplified `AppDevCommand`** from ~180 lines of watcher management
down to ~40 lines that delegate entirely to the orchestrator.
# Introduction
In this PR we start returning a workspace migration post sync so it can
committed and provided within the tarball
## Universal aggregators utils
Created two utils
### deleteUniversalFlatEntityForeignKeyAggregators
Used when building a universal create action, a newly created actions
should not contain any aggregated foreign key so they won't be codegen
in the workspace migration but also they are overriden at uninversal to
flat transpilation anw
### resetUniversalFlatEntityForeignKeyAggregators
Used before validating a new flat entity creation, some validator will
consume the fk aggregator in order to validate integrity, but of
optimstically provided it can result to errors. To avoid caller
responsability we override them here
## create-field-action refactor
Refactored the universal and flat field create action to be following
the base actions in order to ease typing
Also it was tailored to handle unlimited amount of flat field metadata
in the same actions whereas in the reality we were always only sending
at max 2 ( for relation fields )
Note: relation field has to be provided at the same as if not optimistic
would fail to retrieve circular universal identifiers
## ObjectManifest
Now always expect a `labelIdentifierFieldMetadataUniversalIdentifier`
## Integration test
Created an integration test that creates an app, sync a first manifest
and a second implying update workspace migration action generation
## Add application-scoped GraphQL schema generation
When an application token is used to authenticate, the `/graphql` schema
is now dynamically filtered to only include entities belonging to that
application (plus the Twenty Standard Application). This enables
third-party applications and the SDK to introspect a schema that is
relevant to their scope, rather than seeing the full workspace schema
with all custom objects.
### Changes
- **New `generateApplicationToken` mutation** on the `/metadata`
endpoint, allowing callers to exchange an API key for an
application-scoped JWT token
- **Schema filtering by application** in `WorkspaceSchemaFactory` — when
`request.application` is present (from an application token), flat
entity maps are filtered by `[appId, standardAppId]` before schema
generation
- **Per-app caching** — both the Yoga in-memory cache and Redis cache
now include the `appId` in their keys to avoid serving wrong schemas
- **Consolidated `getSubFlatEntityMapsByApplicationIdsOrThrow`** —
unified the single-ID and multi-ID filtering utilities into one
- **Integration tests** covering token generation (admin + API key auth)
and schema introspection filtering (standard app token excludes custom
objects)
Schema generated on seeds with applicationToken (see that pets is
missing)

## Fix resolver schema leaking between `/metadata` and `/graphql`
endpoints
### Summary
- Patch `@nestjs/graphql` to support a `resolverSchemaScope` option that
filters resolvers at both schema generation and runtime, preventing
cross-endpoint leaking
- Introduce `@CoreResolver()` and `@MetadataResolver()` decorators to
explicitly scope each resolver to its endpoint
- Move most resolvers (auth, billing, workspace, user, etc.) to the
metadata schema where the frontend expects them; only workflow and
timeline calendar/messaging resolvers remain on `/graphql`
- Fix frontend `SSEQuerySubscribeEffect` to use the default (metadata)
Apollo client instead of the core client
### Problem
NestJS GraphQL's module-based resolver discovery traverses transitive
imports, causing resolvers from `/metadata` modules to leak into the
`/graphql` schema and vice versa. This made the schemas unpredictable
and tightly coupled to module import order.
### Approach
- Added `resolverSchemaScope` to `GqlModuleOptions` via a patch on
`@nestjs/graphql`, filtering in both `filterResolvers()` (runtime
binding) and `getAllCtors()` (schema generation)
- Each resolver is explicitly decorated with `@CoreResolver()` or
`@MetadataResolver()`
- Organized decorator, constant, and type files under `graphql-config/`
following project conventions
Core GQL Schema: (see: no more fields!)

# Introduction
In this PR we catch all the runner errors coming from a single workspace
migration action execution.
**1. `WorkspaceMigrationActionExecutionException`** (low-level,
action-specific)
- Thrown from action handlers, utils, and helper functions
- Contains specific error codes: `FIELD_METADATA_NOT_FOUND`,
`OBJECT_METADATA_NOT_FOUND`, `ENUM_OPERATION_FAILED`, `NOT_SUPPORTED`,
etc.
- Simple structure: `message`, `code`, `userFriendlyMessage`
- No action context - just describes what went wrong
**2. `WorkspaceMigrationRunnerException`** (high-level, runner-scoped)
- Only two codes: `INTERNAL_SERVER_ERROR` and `EXECUTION_FAILED`
- `EXECUTION_FAILED` **requires** `action` + `errors` (contains the
action context)
- `INTERNAL_SERVER_ERROR` **requires** `message` (no action context)
## Refactor
- Removed the `relatedFlatEntityMapsKeys` from the `WorkspaceMigration`
type as they're directly inferred from passed actions
- Swallowing actions rollbacks errors in order to iterate over all of
them
## Testing
Created a very straigthforward install application from workspace
migration endpoint in order to start testing the introduced
`WorkspaceMigrationActionExecutionException`
Introduced a feature flag that stop the access to the endpoint if not
enabled
Whole taken direction are totally subjective and highly prone to
mutations ( endpoint location, naming and input schema see
`ts-expect-error` comment )
