"scope":"Actual Biome temperature methods, warm/cold/iceberg-melt predicates and precipitation selection, with both temperature modifiers and arbitrary base float bits. Native private climate/biome constructors provide explicit temperature inputs; unrelated biome fields are null and never queried. Fixed seeded simplex/stack sources, float/double conversion and arithmetic order, height adjustment and sea-level overflow, packed-position aliases, repeated queries with changed sea levels, cache capacity/order/content, NaN recomputation and eviction, and actual native thread-local isolation versus independently owned Rust workers. ClimateSettings map-codec parsing additionally covers all independently authenticated bundled biome definitions, direct float conversion, nonfinite overflow, modifier defaults/null handling, field types, duplicates and missing fields. Full biome data codecs, climate encoding, complete weather placement/freezing, material condition integration and automatic migration of shared biome instances between threads remain outside this scope."}
