Run reviewed custom workflow Python
Grant one-invocation trust only after reviewing the source embedded in the project.
Inspect model.automation.source in the .tln project and verify its system-solver labels, file/process behavior, and final model.save() call. Invoke Batch with --trust-workflow and omit -study; custom source selects its solver explicitly. Trust is not persisted and does not sandbox Python, so repeat review when project content changes.
