## Summary - **SSE unification**: Replaced 11 individual SSE effect components with a single generic `MetadataStoreSSEEffect` - **Metadata store cleanup**: Merged `metadataCollectionHashesState` into `metadataStoreState` (currentCollectionHash / draftCollectionHash per entity), moved `objectMetadataItemsSelector` to `object-metadata` domain, converted `navigationMenuItemsState` to a derived selector - **Naming clarity**: Renamed `isAppMetadataReadyState` → `isMinimalMetadataReadyState`, `MetadataGater` → `MinimalMetadataGater`, `useIsLogged` → `useHasAccessTokenPair`, `patchMetadataStoreFromSSEEvent` now takes named object params - **Mock metadata loading**: Added `generate-navigation-menu-items.ts` script, rewrote `useLoadMockedMinimalMetadata` to load full objects/fields/indexes/views/navItems from generated mock data, enabling proper sign-in background rendering (table columns, view picker, navigation) - **Login/logout transitions**: `MinimalMetadataLoadEffect` manages mocked↔real metadata transitions based on auth state, `MainContextStoreProvider` computes context on auth pages for view picker support - **Login redirect fix**: `handleLoadWorkspaceAfterAuthentication` now re-enables `isAppEffectRedirectEnabled` after `loadCurrentUser()` completes, fixing the blocked post-login navigation - **Dead code removal**: Deleted `useRefreshPageLayouts`, `useApplyPageLayouts`, `useStaleMetadataEntities`, `metadataCollectionHashesState`, and all individual SSE effects ## Test plan - [x] Login from welcome page redirects to companies page - [x] Logout transitions cleanly to mocked metadata on welcome page - [x] Sign-in background shows table columns, view picker, and navigation items - [x] SSE events still update metadata store entries correctly - [x] Navigation menu items persist across page refreshes - [ ] CI: lint, typecheck, tests pass

Why Twenty
We built Twenty for three reasons:
CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.
A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.
We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
