## workflowVersion -> core, Phase A Follows #21674 (Phase 0, merged). Base: `main`. Populates core `workflowVersion` and keeps it in sync with the workspace object, so a later phase can switch reads to core. Reads stay on the workspace object in this PR. ### 1. Backfill (upgrade command) `BackfillWorkflowVersionToCoreCommand`, a `@RegisteredWorkspaceCommand('2.20.0', ...)`. Per workspace, reads all workspace `workflowVersion` records and upserts them into core, preserving ids (idempotent), dry-run aware. ### 2. Dual-write (always on, not flag-gated) `WorkflowVersionCoreDualWriteListener` hooks `@OnDatabaseBatchEvent('workflowVersion', CREATED/UPDATED/DELETED)` (same mechanism as the existing workflow-version status listener) and mirrors every mutation into core. Sync failures are logged, never break the user's write; drift is repaired by re-running the backfill command. Dual-write is deliberately not behind a flag: reading from core (next phase) is only safe if core has been continuously in sync since the backfill. An always-on mirror makes "core is fresh" an invariant, so the read switch becomes a plain flag flip. The cost is one extra upsert on infrequent workflowVersion writes. `IS_WORKFLOW_VERSION_IN_CORE_ENABLED` is reserved for the read switch (Phase B): dispatch from the `workflowAutomatedTriggerMaps` cache, runner and builder reading trigger/steps from core. Until then it gates nothing. Both the backfill and the listener go through a single `WorkflowVersionCoreSyncService` (`upsertToCore`/`deleteFromCore`): the workspace-to-core mapping (`trigger` -> `triggers[]`, plus `steps`, `status`, `workflowId`) and `workflowAutomatedTriggerMaps` invalidation live in one place. ### Rollout plan (following phases) - **B, read switch (flag per workspace):** reads move to core; writes keep flowing workspace -> listener -> core. Rollback = flip the flag back, workspace never stopped being source of truth. - **C, contract (code change):** write paths write trigger/steps to core directly; workspace `workflowVersion` stays as a thin shell (nav/relations/search) but drops the trigger/steps columns; listener and flag removed. ### Not in this PR - Reconciliation tooling beyond re-running the backfill. - The read switch (Phase B).

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
