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.

At hop eight, GJ 616 would be settled.

That is the complete summary of every assessment that has been conducted on the system. The K-type primary is adequate. The habitable world meets settlement criteria: breathable atmosphere, stable geology, acceptable water distribution, no significant biological hazard. The transit connections to GJ 853A and GJ 903 give the corridor good bones. At any hop distance up to about nine, the logistics of founding a settlement here would be manageable, the economic case for the agricultural potential would be plausible, and some combination of farming families, opportunists, and idealists would have found their way here by now.

At hop twelve, the logistics of supplying a founding cohort over that distance defeat every proposal before they progress to earnest planning. A founding cohort needs to bring enough to establish themselves before they can produce enough to sustain themselves. At hop twelve, the supply chain for that initial period is expensive, slow, and vulnerable to any disruption in the intervening eleven transit hops. The risk is not the world. The world is fine. The risk is the distance between the world and the point at which the founding cohort no longer needs consistent external supply.

Every settlement proposal for GJ 616 has done the same math and reached the same conclusion. The proposals are archived. The world is still there, meeting its parameters, waiting for someone to solve the distance problem rather than the world problem.


Supply Dependency
