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.

Population

The name is Afrikaans for Cape Bay — the kind of name that arrives with a founding generation carrying specific memories of coastlines they left behind. The Cape Malay community that settled here three hundred years ago came primarily from the coastal south of the African continent, from a heritage that had already absorbed centuries of cultural exchange between indigenous, Malay, Dutch, and East African influences — a hybrid tradition that had learned, long before interstellar emigration was a concept, how to maintain identity while taking on everything useful from the cultures it moved alongside. They brought that habit to a warm coastal world circling a dim M5 star at the end of a spur off Confluência, and they planted spices.

The choice was not accidental. The founding agricultural survey had flagged GJ 213's primary inhabited world — a warm, low-gravity coastal planet with long growing seasons and mineral-rich volcanic soils along its eastern seaboard — as unusually suited to aromatic cultivation. The Cape Malay founders recognized in the survey data something the survey team had not specifically noted: the combination of mineral profile, temperature range, and the peculiar wavelength composition of an M5 star's light through this particular atmospheric depth produced growing conditions that would do extraordinary things to certain spice crops. They knew because they had been growing spices under artificial M-spectrum lighting in cooperative hydroponic facilities back in the emigration transit stage. The planet would do it better and at scale.

Three hundred years later, Kaapse Kruie — Cape Herbs — is the most recognized south_reach spice brand beyond the corridor's own borders. The blend is specific: cardamom, wild tarragon, and three local cultivars that do not have names in any language other than the ones Kaapse Baai's growers have given them — Rooi Geur, Geelpeper, and simply Die Blom, the Flower. The blend cannot be replicated. Growers on three systems have attempted to cultivate the local cultivars from seed; the results were close enough to disappoint the people who could tell the difference and not close enough to satisfy the markets that care. The soil matters. The light spectrum matters. The specific microclimate of the eastern seaboard, where the volcanic mineral deposits interact with the sea-driven humidity cycling that characterizes the growing regions, matters in ways that cannot be decoupled and reinstalled elsewhere.

Kaapse Kruie is not a corporation. It is a growers' collective — currently forty-two member farms, with a certification board that administers provenance standards and a shared export agent that manages the distribution relationships. The collective is small by the standards of south_reach agricultural operations. It is also, per kilogram of exported product, among the most profitable agricultural operations in the south_reach. The blend appears on Mercado's spice shelf across the Reach under the Kaapse Kruie label — the distinctive hand-painted clay-red tin with the botanical illustration of Die Blom that has been the product's packaging since the second generation of production. Core corridor buyers who encounter it tend to describe the flavor as distinctive and difficult to place, which is the polite version of saying it tastes like somewhere they have not been.

The two gates connect to GJ 473A (outward, a less-trafficked spur) and to Confluência (inward). Kaapse Baai is a spur end — there is no gate path beyond it that doesn't return through Confluência. The community has made peace with this topology over three centuries. Being at the end of the line concentrates the community's focus inward. It is not, by south_reach standards, an isolated existence: Confluência is a single gate transit away, and the cooperative distribution relationships that move Kaapse Kruie through Mercado's network and into the wider Reach mean the community maintains active commercial relationships with systems it will never see in person.

The population is Cape Malay in its founding heritage and considerably more mixed in practice — three hundred years of immigration from Confluência and, less frequently, from systems further out have layered Angolan-Portuguese, Swahili-Bantu, and unaffiliated south_reach backgrounds into the community's fabric. The founding community's cultural practices — the music, the cuisine, the particular dialect of Afrikaans-inflected Portuguese that developed locally — have been maintained not as museum pieces but as the water in which newer arrivals swim and eventually absorb.


Supply Dependency

Kaapse Baai exports spices and aromatic agricultural products. Beyond the Kaapse Kruie blend, the collective's member farms produce a range of specialty cultivars sold through smaller distribution relationships across the south_reach. The system imports most of its manufactured goods from Confluência, along with the agricultural equipment that the collective's farms require and the technical infrastructure for the export packaging operations. The spur topology means the community has a single supply corridor; historically this has made the system's residents more attentive to storage capacity and buffer stocks than comparable systems with multiple gate connections.


Faction Notes

The Kaapse Kruie Growers' Collective holds the certification authority for the blend's provenance standards and administers the export agent contract. Its certification board has turned down applications from new farms seventeen times in the collective's history; the board's stated standard — that new members must demonstrate three consecutive harvests meeting the blend specification as certified by existing members — effectively means entry requires relationships that take time to build. The collective is not formally exclusionary. The practical effect of the standards is that the member list changes slowly.

The Settlement Council is a standard elected body with a close working relationship with the collective's certification board. The two institutions share several families across their memberships, which is unremarkable by the community's norms and sometimes remarked upon by commercial interests from outside who were expecting a cleaner institutional separation.


Silence Topic

The three local cultivars — Rooi Geur, Geelpeper, and Die Blom — were not in the founding botanical inventory. The records of where the seeds came from and how they were introduced to the growing operations in the system's first generation are incomplete in a specific way: the cultivation records from the founding decade exist, the sales records from twenty years after founding exist, but the intervening period's botanical provenance documentation is missing from the collective's archive. The collective's position, when the question has come up in certification disputes, is that the founding-era records are simply incomplete, which is common for wave_3 settlements. The commercial implication is that the cultivars' provenance is legally murky in a way that no one has yet found a reason to press — because the collective controls both the seeds and the certification, and the only parties who might benefit from pressing the question are the outside growers who have been trying to replicate the cultivars and failing.


Narrative Hook

A botanical researcher from Lalande's agricultural science program has matched the genetic markers of Die Blom against a pre-settlement database and found a cultivar that appears nowhere in any official emigration botanical inventory — and whose closest relatives are documented as extinct on Earth.


Calibration Note

M5 is a dim red dwarf, consistent with the narrow habitable zone and close-orbit inhabited world. The warm coastal conditions on the inhabited planet reflect the close-orbit positioning and the volcanic mineral geology, which is plausible for a tidally influenced world with active interior geology. Spur-end topology at hop 5 with wave_3 settlement is consistent with the outer south_reach's agricultural extension pattern — spur ends in this region tend to be production systems that selected their positions for resource quality rather than connectivity.
