"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.

Systems below the minimum planet count for their spectral class now
have outer ice/frozen worlds added. Systems missing asteroid belts
have a sparse outer belt inserted. Orbit indices renumbered to stay
monotonic after insertions.
Remaining 5 verify errors are unnamed stations/bodies (content decisions).

Schema: added orbital_period_days and rotation_period_hours to bodies
table. Proposal format now includes surface_gravity, orbital_period_days,
rotation_period_hours with sensible defaults per body type.
New sync-wiki command generates a Celestial Bodies section in wiki
pages from DB data. All 16 fields rendered including Year (d) and
Day (h). Re-authored Gateway (GJ 71) with full physics.
