"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.

GJ 853A has everything the early settlement economic models said was required: a habitable world, mineral deposits of identified commercial value, and corridor connectivity to settled systems on both sides. Early surveys flagged the system as a development priority and filed the reports in the archive where they have remained, updated periodically, for the better part of two centuries.
The habitable world sits in the outer zone of its M-dwarf primary — technically within parameters, but dim in the way that M-dwarf habitable zones are dim. Surface conditions are adequate: breathable atmosphere, liquid water, the essential biological prerequisites. The world is not hostile. It is not warm, and it is not well-lit, and the stellar output that sustains it provides enough energy for survival and not much of what the human body calls comfort. Living here without significant climate and lighting infrastructure would be technically possible and practically unpleasant.
The mineral survey data is more straightforwardly appealing. The primary world's crust contains deposits of processed-goods precursors identified in the original survey as commercially significant by inner-corridor commodity standards. At closer hop distances, that combination — habitable world plus extractable minerals — would have attracted a development operation within decades of the first survey. At hop eleven, behind the particular discouragement of an M-dwarf primary and the logistics costs of a frontier development, the commercial calculus never quite closed.
The survey data circulates. It appears in speculative investment prospectuses that periodically make the rounds in inner-corridor financial markets — documents that accurately describe the deposits, accurately describe the habitability profile, and somewhat understate the per-unit extraction cost at this distance. None of the prospectuses have produced funded development operations. The mineral deposits remain in the crust. The surveys remain in the archive.
Supply Dependency
None.
Faction Notes
No faction presence. The survey archive is maintained by the Assembly's territorial survey authority. Several commercial entities have filed exploratory interest claims; none have advanced to development applications.
Narrative Hook
Rich mineral deposits and a habitable world at hop eleven — everything the economics require except willingness to do it at this distance under this star.
