## Summary - Store SSO connections (Google, Microsoft, OIDC, SAML) as connected accounts in the core schema during sign-in/sign-up, gated behind the `IS_CONNECTED_ACCOUNT_MIGRATED` feature flag - Add `OIDC` and `SAML` to `ConnectedAccountProvider` enum with exhaustive switch handling across frontend and backend - Add `IS_CONNECTED_ACCOUNT_MIGRATED` to `DEFAULT_FEATURE_FLAGS` for new workspaces, with a fallback check so SSO accounts are created even before workspace activation - Always upsert connected accounts to both workspace and core schemas during messaging OAuth flow, fixing FK constraint violations when SSO-only accounts exist only in core - Create message/calendar channels when they don't exist regardless of new vs reconnect flow - Filter settings accounts list to only show accounts that have message or calendar channels ## Test plan - [ ] Sign up with Google SSO → verify connected account is created in core schema - [ ] Connect messaging (Google APIs) after SSO sign-up → verify no FK errors, channels created, configuration page renders correctly - [ ] Reconnect an existing messaging account → verify tokens updated, sync resets triggered - [ ] Sign in with OIDC/SAML SSO → verify connected account created with oidcTokenClaims - [ ] Verify settings accounts page only shows accounts with channels (SSO-only accounts hidden) - [ ] Verify typecheck, lint, and unit 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.
