migration-immutability

What problem does it solve?

Once a migration has been applied in any environment, its content is effectively frozen. Editing an existing deployed migration can cause schema drift across environments and desynchronization between databases.

Core Features & Use Cases

• Enforces the rule that deployed migrations must not be edited in place; changes must be added as new migrations.
• Guides developers to create a new migration with a descriptive name and document the rationale for the change.
• Applies to migrations under server/migrations that have been merged into origin/main and deployed across environments.

Quick Start

Create a new corrective migration and apply it to update the deployed schema.
