### What
Unifies record page layout editing and navigation menu editing into a
single global "layout customization" session. Dashboard editing stays
separate.
### How it works
**Two edit mode systems, one context-based read:**
- `isLayoutCustomizationModeEnabledState` -- global atom for record
pages + navigation
- `isDashboardInEditModeComponentState` -- dashboard-only, independent
per-component atom
- `PageLayoutEditModeProvider` -- context that dispatches to
`RecordPageLayoutEditModeProvider` (reads global atom) or
`DashboardPageLayoutEditModeProvider` (reads component atom), one
component per file
**Session registry + independent atoms:**
- `activeCustomizationPageLayoutIdsState` -- accumulates page layout IDs
as user navigates during customization (`string[]`)
- Save/cancel iterate the ID list and read each layout's draft/persisted
atoms independently
- Follows the same pattern as `settingsRoleIdsState` +
`settingsDraftRoleFamilyState`
**Unified UI:**
- `LayoutCustomizationBar` replaces the old `NavigationMenuEditModeBar`
- Enter once -- edit record layouts + navigation -- save/cancel
everything together
- `useSaveLayoutCustomization` orchestrates sequential save: navigation
draft -- page layouts -- field widget groups
- Error snackbar on partial save failure (with TODO for future atomic
server mutation)
**Draft protection during customization:**
- `PageLayoutRelationWidgetsSyncEffect` guarded -- only updates
persisted state from server, skips draft/currentLayouts while
customization is active
- `useExecuteTasksOnAnyLocationChange` skips draft reset when
customization mode is enabled
- Command execution blocked during layout customization
### Cleanup
- Deleted `NavigationMenuEditModeBar`,
`isNavigationMenuInEditModeState`,
`isPageLayoutInEditModeComponentState`,
`useIsGlobalLayoutCustomizationActive`
- `DraftPageLayout` type changed from `Omit` to `Pick` (explicit fields)
- Removed save/cancel from `DefaultRecordCommandMenuItemsConfig` (bar
handles it now)
- Extracted `useSaveFieldsWidgetGroups` from save orchestration
- Split `PageLayoutEditModeProvider` into 3 separate files (one
component per file, Twenty convention)
### Known issues
- **Stale deleted widget after save (pre-existing on `main`)**: Delete
widget -- save -- exit customization -- Apollo cache stale -- sync
effect overwrites Jotai from stale data -- widget reappears until
refresh. Separate PR needed, likely tied to the planned server-side
`saveLayoutCustomization` atomic endpoint.
### Open questions
- **Module location**: Layout customization hooks/states live in `/app`
-- should they move to their own `modules/layout-customization/`?
- **Atomic server mutation**: All save mutations are on metadata schema
(`createNavigationMenuItem`, `deleteNavigationMenuItem`,
`updateNavigationMenuItem`, `updatePageLayoutWithTabsAndWidgets`,
`upsertFieldsWidget`). A single `saveLayoutCustomization` endpoint could
make saves truly atomic.

## Reduce type leakage between GraphQL schemas
### Why
Twenty runs two separate GraphQL schemas: **core** and **metadata**.
NestJS's `@nestjs/graphql` uses a global `TypeMetadataStorage` that
accumulates all decorated types across all modules. When each schema is
built, every registered type leaks into both schemas regardless of which
module it belongs to.
This means the core schema's generated TypeScript
(`generated/graphql.ts`) contained ~2,700 lines of types that only
belong to the metadata schema (and vice versa). This creates confusion
about type ownership, inflates generated code, and makes it harder to
reason about which API surface each schema actually exposes.
### How
**1. Patch `@nestjs/graphql` to support schema-scoped type resolution**
- **(Already done)** Added a `resolverSchemaScope` option to
`GqlModuleOptions`, allowing each schema to declare a scope (e.g.
`'metadata'`)
- `ResolversExplorerService` now filters resolvers by a
`RESOLVER_SCHEMA_SCOPE` metadata key, so each schema only sees its own
resolvers
- `GraphQLSchemaFactory` now performs a **reachability walk**
(`computeReachableTypes`) starting from scoped resolver return types and
arguments, only including types that are transitively referenced —
handling unions, interfaces, and prototype chains
- Type definition storage and orphaned reference registry are cleared
between schema builds to prevent cross-contamination
**2. Register `ClientConfig` as orphaned type in metadata schema**
Since `ClientConfig` is needed in the metadata schema but not directly
returned by a resolver, it's explicitly declared via
`buildSchemaOptions.orphanedTypes`.
**3. Regenerate frontend types and fix imports**
- `generated/graphql.ts` shrank by ~2,700 lines (types moved to where
they belong)
- `generated-metadata/graphql.ts` gained types like `ClientConfig` that
were previously missing
- ~500 frontend files updated to import from the correct generated file
