jpmschweitzerandClaude Opus 4.6 db241b88bd refactor(schema): rename biome_summary to planet_class (D-188)
"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 394 is the anteroom.

A dim M-dwarf primary, a habitable zone that survey teams consistently describe as technically within parameters and practically marginal — the primary world is cold, dry, and atmospherically sparse in the way that the outer edges of M-dwarf habitable zones tend to produce. Nothing about the system is hospitable. Nothing about it is dangerous in any way that would prevent transit. It exists in the corridor between GJ 177 and Einde at GJ 407, and its primary function in the transit graph is that it connects them.

Anyone traveling to Einde must pass through GJ 394. This is not incidental. The geography of the dead-end corridor means that the experience of reaching the furthest community in this section of the frontier includes a transit hop through an empty, dim, unwelcoming system. The cold world visible in the navigational display during that transit is not quite hostile, not quite habitable, and entirely consistent with the mood of approaching a community that chose maximum distance from institutional authority and settled past an empty space on purpose.

Survey teams have described the primary world as "meeting minimum atmospheric parameters" and "suitable for emergency shelter with appropriate equipment." Neither characterization suggests a settlement opportunity. Neither characterization has been offered in a tone of disappointment, because the survey teams knew what they were looking at.

GJ 394 is a corridor node. It connects two points. It is empty, and its emptiness is appropriate.


Supply Dependency

None.
