+═══════════════════════════════════════════════════════════════════════
+
+REMOVED PARAMETERS:
+  ✗ run_protenix_refold
+  ✗ protenix_diffusion_samples
+  ✗ protenix_seed
+
+NEW PARAMETERS:
+  ✓ run_boltz2_refold          (boolean, default: false)
+  ✓ boltz2_num_diffusion       (integer, 1-1000, default: 200)
+  ✓ boltz2_num_recycling       (integer, 1-10, default: 3)

+
+═══════════════════════════════════════════════════════════════════════
+🎯 KEY IMPROVEMENTS
+═══════════════════════════════════════════════════════════════════════
+
+1. SIMPLIFIED PIPELINE
+   Before: ProteinMPNN → Protenix → JSON → Convert → NPZ → ipSAE
+   After:  ProteinMPNN → Boltz-2 → NPZ → ipSAE
+   
+   ⚡ Eliminated conversion step (43 lines removed)
+   ⚡ Reduced processing time
+   ⚡ Fewer failure points
+
+2. NATIVE NPZ OUTPUT
+   ✓ Direct PAE/PDE/pLDDT matrix output
+   ✓ No Python conversion required
+   ✓ Immediate ipSAE compatibility
+
+3. INTEGRATED AFFINITY PREDICTION
+   ✓ Built-in binding affinity (log IC50 µM)
+   ✓ Native to Boltz-2 output
+   ✓ Complements PRODIGY analysis
+
+4. ENHANCED FEATURES
+   ✓ Recycling iterations for refinement
+   ✓ MSA server option
+   ✓ Diffusion sampling control
+   ✓ GPU acceleration optimized
+
+5. BETTER STABILITY
+   ✓ MIT licensed, fully open source
+   ✓ Active development & support
+   ✓ Stable Docker implementation
+   ✓ Wave + Conda integration
+

+📝 BACKWARD COMPATIBILITY
+═══════════════════════════════════════════════════════════════════════
+
+⚠️  BREAKING CHANGES:
+  - Old Protenix parameters no longer valid
+  - Schema validation will reject old parameter names
+  - Users must update to new Boltz-2 parameters
+
+Migration path for users:
+  --run_protenix_refold true          → --run_boltz2_refold true
+  --protenix_diffusion_samples 5      → --boltz2_num_diffusion 200
+  (protenix_seed removed - use Nextflow seed instead)
