+
+## UI/UX Improvements
+
+### Enhanced Argo UI Visibility
+
+**New Features** (committed in this branch):
+1. **Parameter Display Step**: Dedicated initial step showing all workflow parameters
+   - Item details (ID, source URL, collection)
+   - API endpoints (STAC, Raster)
+   - S3 configuration
+   - Output path
+
+2. **Step Headers**: Clear progress indicators
+   ```
+   ════════════════════════════════════════════════════════════════════════════
+     STEP 1/4: GEOZARR CONVERSION
+   ════════════════════════════════════════════════════════════════════════════
+   ```
+
+3. **Progress Markers**: [1/6], [2/6], etc. for sub-steps within each stage
+
+4. **Section Dividers**: Visual separation between stages with ━━━━━━━━━━━
+
+5. **Final Summary**: Output URLs displayed at completion
+
+6. **Workflow Labels**: Added for filtering in UI
+   - `pipeline.eopf/collection`
+   - `pipeline.eopf/item-id`
+
+---
+
+## S1-Specific Conversion Parameters
+
+From collection registry (`scripts/get_conversion_params.py`):
+```python
+{
+    "pattern": "sentinel-1-l1-grd*",
+    "groups": "/measurements",
+    "extra_flags": "--gcp-group /conditions/gcp",
+    "spatial_chunk": 2048,
+    "tile_width": 512
+}
+```
+
+**Key Differences from S2**:
+- Groups: `/measurements` (S1) vs `/measurements/reflectance/r10m` (S2)
+- Chunk size: 2048 (S1) vs 4096 (S2)
+- GCP handling: Explicit `--gcp-group` flag required for S1
+- Memory: 16GB limit (vs 12GB for S2)
+
+---
+
+## Known Issues & Observations
+
+### Successful Workarounds
+1. ✅ **AMQP Connection**: Fixed by using correct service name (`rabbitmq.core.svc.cluster.local`)
+2. ✅ **Sensor Event Binding**: Fixed by matching event names (`rabbitmq-geozarr/geozarr-events`)
+3. ✅ **Secret Name**: Used `rabbitmq-credentials` (not `rabbitmq-secret`)
+
+### Performance Notes
+- Conversion took ~20 minutes for 30k x 15k resolution S1 GRD
+- Metadata group processing added ~5 minutes
+- Multiscale pyramid generation efficient (using level N-1 as source)
+
+### Preview Generation
+- TiTiler successfully generated XYZ tiles for VH polarization
+- Rescaling: 0-219 (typical for S1 GRD amplitude)
+- Variable path: `/S01SIWGRD_20251007T052723_0025_A350_A991_07A653_VH/measurements:grd`
+
+---
+
+## Conclusions
+
+### ✅ Validation Complete
+- S1 GRD data successfully converted to GeoZarr format
+- Multiscale pyramids generated (6 levels) for both polarizations
+- STAC item registered with all required assets and preview links
+- Preview generation working via TiTiler
+- All metadata groups preserved in output
+
+### ✅ UI Enhancements Successful
+- Argo UI now shows full workflow parameters upfront
+- Step-by-step progress clearly visible
+- Better context during long-running operations
+- Easier debugging with labeled workflows
+
+### 🎯 Production Ready
+The S1 GRD pipeline is ready for production use with:
+- Automated AMQP-triggered workflows
+- Proper error handling and validation
+- S3 output with correct structure
+- STAC API integration complete
+- Preview/visualization support
+
+---
+
+## Next Steps
+
+1. **Apply to Production Namespace**: Deploy enhanced workflow template to production
+2. **Monitor at Scale**: Run on larger S1 dataset (multiple tiles)
+3. **Performance Tuning**: Evaluate Dask parallelization effectiveness
+4. **Documentation**: Update user guide with S1-specific examples
+5. **Collection Registry**: Add more S1 collections (EW, IW, etc.)
