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.

Overview

Braemar was settled 400 years ago by a cohort whose founding documents cite a Scottish highland town as their conceptual reference point — a place of cold uplands, pastoral work, and unhurried permanence. They found a G0V star that burns slightly cooler than the Sun, a world with long winters, shortened summer growing seasons, and grassland plains interrupted by dark ridge formations that reminded the first arrivals of the hills they had named themselves after.

They brought their husbandry traditions and adapted them. The local fauna proved incompatible with Earth-origin livestock in the direct sense — the biochemistry wouldn't align — but the ecological niche was available, and within two generations the settlers had developed working relationships with a native grazing species: the brach, a six-limbed herbivore roughly the mass of a large sheep, with dense insulating fiber that proved, after several decades of selective breeding and processing development, to be extraordinarily useful.

Brach fiber is the material basis of thrds.

The brand did not begin as a brand. It began as a practical vocabulary: "threads" was what the settlement's fiber-workers called their output, shortened in local speech to the form that eventually became a registered mark. Three hundred years of cold-weather refinement produced a fiber product with specific thermal properties — the insulation gradient is unusual, staying comfortable across a wider temperature range than most synthetics — and a generation of designers, working from Braemar's accumulated knowledge base, produced garments that were adopted first by outer corridor workers who needed practical cold-weather clothing, then by the transit corridor's aesthetic culture, which discovered that what worked was also good-looking.

thrds is now one of the better-known consumer brands in the north_reach. Its garments move through markets at Havnfjord and Calloway Reach and further inward, occasionally appearing at corridor fashion markets as far as Wolf 359 territory. The brand's creative direction has remained at Braemar — this is not a case of a product being extracted from its origin community by outside capital. The ownership structure is a local cooperative with the founding families' descendants holding governance rights. The designers who define the aesthetic live here, in a community that is simultaneously pastoral and cosmopolitan, which produces a distinctive tension.

The wealth thrds has brought is real and recent in relative terms — significant accumulation within the last two generations — and Braemar has not fully resolved what to do with it. The pastoral identity, the brach-herders on the highland plains, the slow seasons and practical culture: all of that remains the community's self-image. The thrds design studios and the corridor buyers who visit them represent something different. Both are Braemar. They do not always agree on what that means.


Economy

Brach husbandry and fiber production form the material base. The thrds cooperative is the dominant economic institution, integrating raw fiber sourcing, processing, design, and distribution under a single governance structure. Secondary industries include agricultural food production (the G0V star provides adequate growing seasons) and a modest technical services sector supporting the gate infrastructure.

The loop topology connecting to Havnfjord (GJ 3622) and Calloway Reach (GJ 3325) means Braemar has two outward connection points, which has historically aided the thrds distribution network by giving it routing flexibility.


Supply Dependency

Braemar is largely self-sufficient in food and primary materials. Gate infrastructure components route inward through Havnfjord. The thrds operation exports substantially more than it imports, giving Braemar a positive trade balance unusual for a hop-5 loop member. Technical equipment for fiber processing — precision looms, tensioning rigs, dyeing infrastructure — is sourced from inward corridor suppliers, primarily through Havnfjord connections.


Faction Notes

thrds Cooperative — the dominant institution. Has governance representation on local civic bodies commensurate with its economic weight. The current creative director, Mira Callum-Brennan, is the most publicly visible person in the system and has opinions about local governance she does not always keep to herself.

The Brach Herders' Association — represents the upstream fiber suppliers. Has a complex relationship with the Cooperative: dependent on thrds prices for viability, but collectively the largest single vote bloc in Cooperative governance and therefore not without leverage. Tensions rise when Cooperative designers want specific fiber characteristics that herders consider impractical to breed for at scale.

The Old Holdings Committee — an informal grouping of families whose land grants predate the thrds era and who feel their interests in pastoral continuity are being subordinated to the brand's aesthetic and commercial needs. Advocates for limits on development in highland grazing areas.


Silence Topic

The thrds cooperative has received acquisition inquiries from three inward corridor holding companies over the past decade. All three inquiries have been declined and none have been publicly disclosed. Local governance does not require public disclosure of acquisition inquiries. The herders' association and the old holdings families are not aware the inquiries occurred.


Narrative Hook

A junior accountant at the Cooperative's financial office has been quietly compiling a parallel record of the acquisition inquiries and the governance communications that followed — not to expose anyone, but because she suspects the current creative director has been negotiating terms rather than simply declining.


Calibration Note

GJ 475 is catalogued as Chara — a real G0V star at 27.5 ly. The "cold dim M-type world" description in the briefing is adjusted: a G0V star is slightly cooler than the Sun but broadly similar in character, not a dim red dwarf. The pastoral/cold-climate character is retained by placing the inhabited body in an orbital position that produces long cold seasons and shorter summers — plausible for a G0V system with a world at the appropriate distance.
