## Summary - Migrates 4 entities (`connectedAccount`, `messageChannel`, `calendarChannel`, `messageFolder`) from per-workspace schemas to the shared `core` metadata schema - Introduces a `IS_CONNECTED_ACCOUNT_MIGRATED` feature flag to control the migration: when enabled, reads come from core metadata and all writes are dual-written to both workspace and core - Extracts 12 enums from workspace entity files to `twenty-shared` for reuse across frontend and backend - Creates new TypeORM entities, metadata services, GraphQL resolvers/DTOs, and exception interceptors per entity - Each entity owns its own data access module (`ConnectedAccountDataAccessModule`, `MessageChannelDataAccessModule`, `CalendarChannelDataAccessModule`, `MessageFolderDataAccessModule`) — no umbrella infrastructure module - Adds a 1.20 upgrade command that backfills data from workspace schemas to core (preserving UUIDs) and enables the feature flag - Replaces direct repository access with data access service calls across ~50 files in messaging, calendar, and connected-account modules - Adds `lastSignedInAt` and `oidcTokenClaims` fields to the new `ConnectedAccountEntity` - Drops unused `lastSyncHistoryId` field from the migrated connected account entity ## Test plan - [x] Lint passes (`npx nx lint:diff-with-main twenty-server`) - [x] Typecheck passes (`npx nx typecheck twenty-server`) - [x] All unit tests pass (477 suites, 4267 tests, 0 failures) - [ ] Manual test: verify messaging sync works with feature flag disabled (existing behavior) - [ ] Manual test: run upgrade command on a workspace, verify data backfilled to core tables - [ ] Manual test: verify messaging/calendar sync works with feature flag enabled (dual-write path) - [ ] Manual test: verify GraphQL metadata resolvers return correct data when flag enabled

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.
