## Summary - Move `BackfillNavigationMenuItemTypeCommand` from the 1-19 to the 1-20 upgrade path and split the DB transaction into two phases (data backfill, then schema changes) to avoid the PostgreSQL error "cannot ALTER TABLE because it has pending trigger events." - Fix backfill logic to prefer `OBJECT` over `VIEW` for navigation menu items that have `targetObjectMetadataId`, and correct already mis-typed items. Tighten the `CHECK` constraint to enforce `viewId IS NULL` for `OBJECT` type items. - On the frontend, force `navigationMenuItems` into `staleEntityKeys` when the server's `minimalMetadata` response omits the collection hash (happens when the Redis cache hasn't been warmed after an upgrade), ensuring the sidebar loads navigation items. ## Test plan - [ ] Upgrade from 1.18 or 1.19 to 1.20 and verify the migration completes without errors - [ ] Verify navigation menu items of type `OBJECT` do not have a `viewId` set in the database - [ ] Sign out and sign in — confirm navigation menu items appear in the sidebar on first load - [ ] Verify `VIEW`-typed items also appear correctly in the sidebar Made with [Cursor](https://cursor.com)

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.
