Migrates `twenty-front`, `twenty-sdk`, and
`twenty-front-component-renderer` from `twenty-ui-deprecated` to
`twenty-ui` (mechanical import swap — the packages have API parity) and
deletes the deprecated package along with its workspace/CI/config
wiring.
Also adds `@linaria/react`/`@linaria/core` as direct deps of
`twenty-front` (it used them transitively via the deprecated package).
Note: move the required status check from `ci-ui-status-check` to
`ci-new-ui-status-check`.
Argos: the Storybook box-model/button-reset baseline shift (the bulk of
the visual diffs) is isolated in #21665 — Storybook now loads
twenty-ui's global `reset.scss`, which the production app already ships.
Once #21665 merges and this branch is rebased, the remaining Argos diffs
are component-level visual-parity items only.
## Description
Promotes the next-gen UI library (formerly `twenty-new-ui`) to the name
**`twenty-ui`** (v0.1.0, publishable) and renames the old package to
**`twenty-ui-deprecated`**. Rewrites ~1,730 `twenty-ui` imports →
`twenty-ui-deprecated`, updates all configs/CI/Docker/deps, and migrates
twenty-front's `Toggle` to the new package (first consumer) as a
drop-in.
## Next steps
- Wire the `ui/v*` publish dispatch (`cd-deploy-tag.yaml` +
`.yarnrc.yml`), then tag `ui/v0.1.0` to publish.
- Continue migrating components from `twenty-ui-deprecated` →
`twenty-ui`.
## Summary
- Renames `ObjectMetadataItem` to `EnrichedObjectMetadataItem` across
the entire frontend (~440 files) to clarify that this type includes
derived fields (`readableFields`, `updatableFields`, nested `fields[]`,
`indexMetadatas[]`) computed at read time from the metadata store
- Creates `splitObjectMetadataGqlResponse` that goes directly from a
GraphQL `ObjectMetadataItemsQuery` response to flat store items
(combining the old
`mapPaginatedObjectMetadataItemsToObjectMetadataItems` +
`splitObjectMetadataItemWithRelated` two-step flow into one call)
- Removes `ObjectMetadataItemWithRelated` type and all "WithRelated"
naming
- Renames `generatedMockObjectMetadataItems` to
`generateTestEnrichedObjectMetadataItemsMock` to make it clear this is
test-only enriched data
- Deletes `useLoadMockedObjectMetadataItems` hook (consolidated into
`useLoadMockedMinimalMetadata`)
- Ensures nothing destined for the metadata store computes
`readableFields`/`updatableFields` (preventing the localStorage bloat
from #18809)
## Type hierarchy (before → after)
**Before:**
```
ObjectMetadataItemsQuery → mapPaginated → ObjectMetadataItemWithRelated → enrich → ObjectMetadataItem
→ split → FlatObjectMetadataItem (store)
```
**After:**
```
ObjectMetadataItemsQuery → splitObjectMetadataGqlResponse → FlatObjectMetadataItem (store)
→ mapPaginated + enrich (tests only) → EnrichedObjectMetadataItem
```
## Test plan
- [x] `npx nx typecheck twenty-front` passes
- [x] `npx nx test twenty-front` passes (767 suites, 4505 tests)
- [x] `npx nx lint twenty-front` passes
- [ ] CI checks pass

## Summary
Closes#18673
Some languages (e.g., German "Unternehmen") and even English words
(sheep, deer, aircraft, series) have identical singular and plural
forms. Twenty previously blocked saving when labels matched, making it
impossible to correctly name objects in these cases.
- **Labels** are purely display strings — removed the equality
validation from both the frontend Zod schema and backend validator
- **API names** (nameSingular/namePlural) must stay different since they
generate distinct GraphQL resolvers (`findOne` vs `findMany`,
`createOne` vs `createMany`, etc.) and REST endpoints — this validation
is preserved
- Added a shared `computeMetadataNamesFromLabels` util in
`twenty-shared` that auto-appends `'s'` to the plural API name when both
labels produce the same camelCase name (e.g., "Unternehmen" →
`unternehmen` / `unternehmens`)
- Both the frontend form and backend sync-check use the same shared util
— single source of truth, no duplicated logic
**No retroactive impact**: since the old code prevented identical labels
from ever being saved, no existing workspace has `labelSingular ===
labelPlural`.
## Test plan
- [x] New unit tests for `computeMetadataNamesFromLabels` (7 tests:
standard labels, Sheep, Unternehmen, Aircraft, empty labels, different
labels, applyCustomSuffix)
- [x] Updated frontend schema validation tests (identical labels with
different names now passes; identical names still fails)
- [x] Updated backend integration test cases (removed identical-label
failing cases)
- [ ] Manual: create a new object with identical singular/plural labels
(e.g. "Sheep" / "Sheep") — should save successfully with API names
`sheep` / `sheeps`
- [ ] Manual: verify existing objects with different labels still work
unchanged

## Overview
This PR implements **generic many-to-many relation support** through
junction tables (also known as associative entities or join tables).
This replaces the need for hardcoded taskTarget/noteTarget logic and
provides a flexible foundation for modeling complex entity
relationships.
## Architecture
### Data Model
Many-to-many relationships are implemented using a **junction object
pattern**:
```
┌─────────┐ ┌──────────────────┐ ┌─────────┐
│ Pet │──────>│ PetRocket │<──────│ Rocket │
│ │ 1:N │ (junction) │ N:1 │ │
│ rockets ├───────┤ pet : Pet ├───────┤ │
└─────────┘ │ rocket : Rocket │ └─────────┘
└──────────────────┘
```
The junction object (PetRocket) has:
- A `MANY_TO_ONE` relation to **Pet** (the source)
- A `MANY_TO_ONE` relation to **Rocket** (the target)
The source object (Pet) has a `ONE_TO_MANY` relation pointing to the
junction, with **field settings** that specify which target field to
follow.
### Field Settings Schema
Junction configuration is stored in `FieldMetadataRelationSettings`:
```typescript
{
relationType: "ONE_TO_MANY",
// Points to the target field on the junction object
junctionTargetFieldId?: string; // For regular relations
junctionTargetMorphId?: string; // For polymorphic relations
}
```
**Two configuration modes:**
1. **`junctionTargetFieldId`** - References a specific `RELATION` field
on the junction
2. **`junctionTargetMorphId`** - References a `morphId` group for
polymorphic targets (e.g., link to Person OR Company)
### GraphQL Query Generation
When a junction relation is detected, the GraphQL fields are generated
to fetch the nested target:
```graphql
query GetPetWithRockets {
pet(id: "...") {
rockets { # ONE_TO_MANY to junction
id
rocket { # Target field on junction
id
name
__typename
}
}
}
}
```
For polymorphic junction targets:
```graphql
caretakerPerson { id, name }
caretakerCompany { id, name }
```
## Frontend Architecture
### Display Flow
1. **Detection**: `hasJunctionConfig()` checks if field has junction
settings
2. **Config Resolution**: `getJunctionConfig()` resolves junction object
metadata and target fields
3. **Record Extraction**: `extractTargetRecordsFromJunction()` extracts
target records from junction records
4. **Rendering**: Target records displayed as chips (not junction
records)
### Edit Flow
1. **Picker Opening**: Initializes the multi-record picker with:
- Searchable object types (derived from junction target fields)
- Pre-selected items (extracted from existing junction records)
2. **Selection Handling**: Manages create/delete of junction records:
- **Select**: Creates new junction record with source + target IDs
- **Deselect**: Finds and deletes the junction record
- **Optimistic Updates**: Manually updates Recoil store before API call
### Key Trade-offs
| Decision | Trade-off |
|----------|-----------|
| Junction records managed manually | More control over optimistic
updates, but requires manual cache management |
| Settings stored per-field | Flexible (same junction can power
different views), but requires UI to configure |
| Polymorphic via morphId groups | Supports N target types, but adds
query complexity |
| Feature flag gated | Safe rollout, but requires flag management |
## Backend Changes
- **Validation**: Junction target field must exist and be a valid
`MANY_TO_ONE` relation
- **Settings**: Extended `FieldMetadataRelationSettings` type with
junction fields
- **Dev Seeder**: Added sample junction objects (PetRocket,
EmploymentHistory, PetCareAgreement) for testing
## How to Test
1. Enable the `IS_JUNCTION_RELATIONS_ENABLED` feature flag
2. Create objects with junction pattern (Pet → PetRocket → Rocket)
3. Configure the junction target in field settings (advanced mode)
4. Verify:
- Display shows target objects (Rockets), not junction records
(PetRockets)
- Picker allows selecting/deselecting targets
- Changes persist correctly

# Introduction
This PR contains around ~+300 tests + snapshot additions
Please check both object model creation and edition
Closes https://github.com/twentyhq/core-team-issues/issues/355
Refactored into two agnostic forms the Object Model settings page for
instance `/settings/objects/notes#settings`.
## `SettingsDataModelObjectAboutForm`
Added a new abstraction `SettingsUpdateDataModelObjectAboutForm` to wrap
`SettingsDataModelObjectAboutForm` in an `update` context
Schema:
```ts
const requiredFormFields = objectMetadataItemSchema.pick({
description: true,
icon: true,
labelPlural: true,
labelSingular: true,
});
const optionalFormFields = objectMetadataItemSchema
.pick({
nameSingular: true,
namePlural: true,
isLabelSyncedWithName: true,
})
.partial();
export const settingsDataModelObjectAboutFormSchema =
requiredFormFields.merge(optionalFormFields);
```
## `SettingsDataModelObjectSettingsFormCard`
Update on change
Schema:
```ts
export const settingsDataModelObjectIdentifiersFormSchema =
objectMetadataItemSchema.pick({
labelIdentifierFieldMetadataId: true,
imageIdentifierFieldMetadataId: true,
});
```
## Error management and validation schema
Improved the frontend validation form in order to attest that:
- Names are in camelCase
- Names are differents
- Names are not empty string ***SHOULD BE DONE SERVER SIDE TOO*** ( will
in a next PR, atm it literally breaks any workspace )
- Labels are differents
- Labels aren't empty strings
Hide the error messages as we need to decide what kind of styling we
want for our errors with forms
( Example with error labels )
