"Biome" describes per-zone vegetation classification (Whittaker table).
"Planet class" describes overall planetary character. The conflation
caused the planet generator to misclassify ~270 bodies as barren.
Scope: systems.db column, schema SQL, Rust atlas code, wiki table
headers (Biome → Class), atlas proposal JSONs, all docs/decisions,
tooling scripts. Also normalizes atmosphere vocabulary (breathable →
standard) and expands planet class mapping to all 26 wiki values.
Unknown classes default to temperate for modder safety.

1. GJ 111: spectral_class F5V → F5/F6V to match wiki (subgiant)
2. GJ 3943: spectral_class k-m → K5V+M3V (valid MK notation for binary)
3. GJ 903: write wiki prose — was empty stub with only body tables
