 ### Initial Testing
-🔄 **Job ID 3445081**: Development test (30min) - PENDING
-- Command: `./submit_job.sh dev`
-- Status: Waiting for resources on dev_accelerated partition
-- Purpose: Verify DPPO can run on HoReKa with basic pre-training
+✅ **DPPO Confirmed Working on HoReKa**
+- Successfully completed dev test (Job ID 3445106)
+- Pre-training working: 2 epochs, loss reduction 0.2494→0.2010
+- Model checkpoints saved correctly
+- Ready for full experiments
