- Changed workflow.ExecuteActivity(actCtx, activity.LLMInferenceActivity, ...) to workflow.ExecuteActivity(actCtx, "LLMInferenceActivity", ...) - Fixes WorkflowTaskFailed error on first execution - Matches Temporal Go SDK best practices (determinism requirement) - Workflow now executes cleanly on first attempt without retries - Timeline: 5 events instead of 8, 0 failures instead of 1
