Your planet is rich in sodium (10.8%) and chlorine (7.2%) but starved of hydrogen (2.4%), so instead of a water cycle it precipitates its salt into blinding evaporite flats.
Salt worlds need real halite chemistry - sodium and chlorine together, not just one - plus a dry recipe, since any real water cycle would dissolve the crust as fast as it forms. A warm 250-500K band keeps brines mobile enough to precipitate at the surface: halite plains, brine pans, salt-crusted ridges.
Classification Criteria:
✓ Sodium: 10.8% + Chlorine: 7.2% (min 3% each, 12% combined)✓ Hydrogen: 2.4% (<5% - dry enough for evaporites)✓ Temperature: 393K (250-500K warm band)✓ Silicon + Iron + Magnesium: 53.0% (>=15% - a rocky base to salt-crust over)

Very dry - minimal water - likely as steam

Slow rotation - significant day/night temperature variations, but life can adapt
