SCHEMA_DRIFT

What it means. Rolling back code only: the database schema changed after the target version.

What to do. If the older code fails against the current database, go forward again to the newer version, or fix the code forward. Restoring the data from before a change is not available yet.

• HTTP status: 422
• Retryable after applying the fix: yes

Every failure from the CLI or an MCP tool has this shape:

{
  "ok": false,
  "code": "SCHEMA_DRIFT",
  "message": "Rolling back code only: the database schema changed after the target version.",
  "fix": "If the older code fails against the current database, go forward again to the newer version, or fix the code forward. Restoring the data from before a change is not available yet.",
  "file": "<where to edit, when known>",
  "retryable": true,
  "docs": "https://docs.uarpie.app/errors/SCHEMA_DRIFT"
}

Apply fix (edit file when it is given), then run the same command again.
