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.

Supply Dependency

Grünfeld's name is aspirational in the way that many Wave 4 settlement names are: the founding consortium called it "green field" and meant it literally, having surveyed a habitable body with soil conditions that could, with significant amendment and infrastructure investment, support agriculture. They were not wrong. They were also not as right as the name implies.

The soil amendment took two generations. The crops that eventually took hold are a narrow list suited to a dim M-dwarf environment with limited photosynthetic flux: modified root vegetables, a few grain varieties developed specifically for low-light growing cycles, and fungi operations that are insensitive to the light environment entirely. Grünfeld feeds itself and exports a modest surplus — mushroom products and specialty root varieties that have found a niche in the western corridor's food supply. It is not Ran. It is not trying to be. But a loop member that can supply its own food is notably more stable than one that cannot, and Grünfeld's slow agricultural development has produced a population with a genuine stake in the land in a way that purely extractive settlements do not.

The system's position on the Caldwell Point loop creates a dependency relationship: most finished goods arrive via Caldwell Point, and most export freight routes back through it. GJ 783A, the loop's other neighbor, is a quieter community that trades agricultural goods with Grünfeld on barter terms.

Faction Notes

Grünfeld is governed by an elected council with strong representation from the agricultural cooperatives that collectively own most of the arable land. The cooperatives were established early in Wave 4 as a practical necessity — individual settlers lacked the capital to run soil amendment operations at scale — and they have become the system's primary political institution over time. Council membership tracks cooperative leadership closely enough that the two bodies are functionally the same community of people, which produces efficient governance and limited opposition.

The Guardians of Autonomy have a small chapter here that is unusual in its focus: most Guardian chapters in the west corridor work on corporate labor questions, but Grünfeld's chapter is primarily concerned with land tenure and the slow process by which the largest cooperative has been acquiring land from the smallest ones through preferential credit arrangements. It is a quiet concern, not a political crisis. The largest cooperative is locally governed and not affiliated with any outer-corridor corporate structure, which makes the Guardians' case harder to argue.

Assembly presence at hop 4 is structural — delegates visit annually, assessment payments are made, there are no active compliance issues. The cooperatives do not have strong Assembly opinions either way; their primary political horizon is the loop.

Silence Topic

What Grünfeld does not examine: the soil rights register and the slow consolidation happening within it.

The original Wave 4 land grants distributed agricultural parcels across several dozen founding families and a handful of incorporated cooperatives. The largest cooperative — the Grünfeld Agricultural Consortium — has been acquiring distressed parcels through debt-consolidation arrangements for approximately sixty years. The register is public but complex, and the pattern is not obvious without analysis spanning the full document set. The sellers are families whose second or third generation found the agricultural life less appealing than the founding generation did and accepted buyout terms that seemed reasonable at the time. Whether the Consortium's accumulation will eventually produce a governance capture situation — where the cooperative holding most of the land also holds most of the council seats — is the question the current council is not asking.

Narrative Hook

Three generations of patient land acquisition have put one cooperative within a few contested parcels of controlling everything a loop-system's council needs to govern with, and the families selling the last parcels do not fully understand what they are selling.

Calibration Note

wave_4 at hop 4 is slightly later than might be expected for a system this close to Gateway, which reflects the M2V star's dim output limiting agricultural viability until adapted crop varieties made the economics work. The aspirational German name is consistent with the west_reach corridor tendency and with the founding-intention naming pattern — this is what the settlers hoped to build, carried as a name. loop_member topology creates the dependency on Caldwell Point and the relationship with GJ 783A that defines the system's economic horizon. No corporate industrial presence means governance has stayed local, which is characteristic of agricultural Wave 4 systems throughout the corridor.
