Script version mismatch causing 409 during CLI push in AU-1 BYOC

Does anyone understand why the API rejects valid script payloads during automated deployment? Terraform plan shows no changes, but apply fails with 409 Conflict. The version_number in state differs from the API response.

{
 "version_number": 12,
 "name": "Sales_Inbound_v2",
 "enabled": true,
 "default_version": true
}

Environment: AU-1 BYOC, CLI v2.1.0. Local validation passes. API rejects on push phase only.
