Make check-model-exists and check-models-exist consult the workflow scanner while Workflow management is enabled, including the downloaded-history fallback, so Civitai cards can show workflow versions and download state.
Return workflows_disabled from model-versions-status instead of the generic unsupported reason, and add a structured workflows_no_paths reason to the download refusal when no workflow root is configured. Expose workflow_folder_paths as a one-item compatibility list alongside the newer single workflow_path setting so the browser extension can keep pre-flighting downloads.
