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

Traagwater depends on Rana (GJ 150) for the manufactured goods and processed materials its agricultural economy does not produce. The dependency is ancient and well-managed: six hundred years of trade through a single gate has produced stable commercial routines, familiar faces on both sides, and a price relationship that fluctuates very little. Rana's redistribution business benefits from a captive agricultural supplier; Traagwater's agricultural surplus finds a reliable market at Rana's warehousing terminals. Neither system has any particular interest in changing this arrangement.

The primary habitable world is water-rich, temperate, and slow. Three large shallow seas dominate the surface geography. Tidal patterns are gentle — the K5V primary is quiet and the moon configuration produces minimal tidal stress. The early Dutch-heritage settlers, who arrived in Wave 1 as part of an agricultural development program, named the system for the quality of water movement they observed everywhere: sluggish rivers, slow tides, a landscape that did not hurry. Traagwater. Slow water. The name was meant as a practical descriptor for the survey record. It became the name because no one thought of a better one before the first generation was gone.

The agricultural output — primarily wetland-adapted grain varieties, cultivated fish stocks, and a distinctive fermented product made from a local seed crop — has been exported through Rana for five hundred years. By now the agricultural techniques have drifted significantly from their Earth analogs. The Traagwater farming cooperative maintains its own seed banks, its own cultivation records, and its own fermentation traditions. What they produce is recognizably descended from Dutch-heritage aquaculture and cereal farming, but it is something local now, not a transplant.

Faction Notes

Traagwater is governed by a farming cooperative council that is, functionally, the same institution the Wave 1 founders established under their original settlement charter. The names have changed. The structure has not. Council seats are allocated by land holding within the cooperative system — which means long-settled families have more weight than recent arrivals, and the oldest founding-lineage families have the most. This is not contested. The governance model has been successful for long enough that its structural assumptions read as natural rather than designed.

Assembly authority is a name on a document. The Wave 1 charter is Assembly-registered; the system has not filed compliance paperwork in living memory; no Assembly agent has visited in anyone's lifetime. The cooperative council knows the Assembly exists in the abstract and regards it as something that happens in places where people cannot work things out among themselves. The Compact of Westphalia is equally abstract. The corridor's political disputes feel very distant from a wet agricultural world whose gate opens onto a redistribution junction.

Gate Corporation presence is minimal: a rotating maintenance technician visits the single aperture on an annual schedule. The technician routes through Rana (GJ 150) on the annual maintenance cycle, which has produced the system's most reliable news channel about the wider corridor — whatever the Gate Corp technician knows, Traagwater knows a day later.

The Dutch cultural heritage is present in deep structure: architectural vocabulary in the older farming estates, naming traditions within founding-lineage families, a calendar that marks festivals with Low Dutch origins now six centuries evolved. The living culture is West Reach frontier agricultural, not Dutch. But the bones of the heritage are visible if you know where to look.

Silence Topic

The founding-lineage families collectively hold land grants that, under the original Wave 1 charter, are documented in Assembly records as provisional — subject to renewal under settlement performance criteria. No one has invoked those criteria in five hundred years, and the Assembly almost certainly lacks both the records and the institutional will to do so. But the grants were never formally converted to permanent title under the Assembly's later settlement law, which created a permanent-title pathway that Wave 1 systems were supposed to use but many never did. If the Assembly were ever to examine Traagwater's land tenure structure, several founding families would discover that their six-hundred-year-old farms rest on provisional grants. The cooperative council's legal records contain a single notation from a Wave 3-era council secretary who identified the issue and concluded, correctly, that no one was going to press it.

Narrative Hook

Six hundred years of quiet agricultural life on a slow-water world at the end of a dead_end spur — and the land tenure that the founding families have never questioned rests on provisional Wave 1 grants that no one formally converted to permanent title.

Calibration Note

wave_1 settlement at hop 7 in a dead_end is unusual and worth explaining: Wave 1 agricultural programs sent settlement parties along the early mapped gate paths before the full topology was understood. A dead_end at this hop distance would have been an early frontier position in Wave 1, not an isolated backwater. By the time the Reach's full topology was mapped, Traagwater was already established and simply remained where it was. The K5V classification matches the header. dead_end with one gate to Rana is accurate. The Dutch-heritage founding is consistent with west_reach corridor Germanic/Scandinavian/Central European inflection — Dutch heritage falls within the corridor's cultural envelope.
