## Context When an application defined custom permission flags and a role referencing them in the same sync, installation failed, first at validation (Permission flag not found) and then at execution (Migration action 'create' for 'rolePermissionFlag' failed). Root cause: both the migration builder order and the runner execution order processed rolePermissionFlag before permissionFlag, so the role's flag assignments were validated/inserted before the flags they reference existed. ## Changes - Builder order: run the permissionFlag builder before rolePermissionFlag so newly created flags are visible in the optimistic maps when assignments are validated. - Execution order: order the permission-flag actions so definitions are created before assignments, and assignments deleted before definitions, keeping the FK satisfied in both directions. - In-use check: move the "flag still assigned to a role" guard out of the per-entity deletion validator (order-dependent, false-positived when a flag and its assignments were deleted together) into a new order-independent validatePermissionFlagNotInUseCrossEntity (aligned with existing validateObjectMetadataCrossEntity, validateViewFieldLabelIdentifierCrossEntity, ...), run after all builders against the migration's final state. This fixes both the create path (define flag + reference it in one sync) and the teardown path (delete flag + its assignments in one sync). <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/21742?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

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.
