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.

Yeongwol is the corridor in motion. Two apertures, one pointing back toward Miryang and one pointing deeper into unsettled space beyond — a community built around the fact that it is neither the beginning nor the end of anything, but the necessary middle. The name comes from a county in the Korean interior, a place historically known as somewhere travelers passed through on their way to somewhere else, and the founders of Yeongwol chose it with a self-awareness that three hundred years of history have justified.

The system's star — a flare-active M5Ve — is aggressive enough that surface settlement was ruled out early. Everything is in orbit or shielded subsurface on the system's two rocky inner bodies. Yeongwol Orbital, the primary habitation structure, was designed by Wave 3 engineers who understood they were building for a community that would grow through transit rather than in-system expansion, and the station reflects that: it is long and modular, capable of extending berth capacity in either direction, and has in fact been extended fourteen times in three centuries. The oldest sections are noticeably dimmer than the new ones, lit with the amber-shifted spectrum that early wave_3 installations used before the corridor standardized its illumination protocols.

The through-route function defines Yeongwol's political economy. Traffic moving outward from Miryang stops here to resupply, recalibrate gate readings, and file transit documentation. Traffic moving inward does the same in reverse. The Yeongwol Passage Authority — the governing body with the least glamorous mandate in the corridor — has turned this into a genuine power base by controlling the processing time and inspection standards for everything that passes through. Slow an outbound convoy by three days and someone notices. Slow it by three weeks and someone with money starts asking questions.

Three hundred years of throughput have produced a community with more opinions about other people's business than their own. Yeongwol's civic culture is observant, analytical, and — in the east_reach's polite formulation — highly informed. The local networks carry more gossip about conditions in adjacent and distant systems than any other node in this part of the corridor. Whether this constitutes a community skill or a community pathology is a matter of perspective.


Supply Dependency

Yeongwol depends on Miryang (GJ 754) for agricultural commodities — a consistent flow given Miryang's established role as a corridor breadbasket. The through-route position means Yeongwol can also source opportunistically from transit traffic, buying from convoys at favorable rates in exchange for preferential processing times. The Passage Authority's informal "transit commodity exchange" operates in a legal gray zone the Assembly has declined to regulate, possibly because the Assembly's own supply logistics benefit from it.


Faction Notes

The Yeongwol Passage Authority governs through a director-council structure that blends transit management and civic administration in ways that make it difficult to distinguish between a service body and a governing body. This ambiguity is a feature, not a bug; the Authority's founders were explicit about designing governance that could not be easily separated from the system's economic function.

The Transit Scholars are an informal academic community that has evolved around Yeongwol's unique position as a through-route node. They study traffic patterns, corridor dynamics, and the sociology of transit communities — producing a body of literature that is respected in academic corridors and largely ignored in the systems it describes.

The Outer Trade Collective represents merchants, couriers, and independent operators moving goods beyond Yeongwol toward the deeper corridor. The Collective has been lobbying the Passage Authority for a decade to improve facilities on the outbound side, arguing that the inbound processing infrastructure receives more investment than the outbound because the Authority's personnel have more personal connections with Miryang-facing traffic.


Silence Topic

The inspection records: Yeongwol's Passage Authority maintains detailed logs of every transit that passes through the system, including cargo manifests, crew biometrics, and declared route plans. What the Authority does with that data — who has access to it, whether it is shared with Assembly Intelligence, whether it has been sold — is something the director-council discusses in closed session and does not publish. Three separate Freedom of Transit Act petitions have been filed in the past twenty years asking for access to the data governance policy. All three are pending.


Narrative Hook

A routine transit inspection at Yeongwol flags a cargo manifest whose declared contents don't match the weight readings — and the Passage Authority's response to the discrepancy, instead of escalating to Assembly inspection, is to quietly wave the convoy through with a notation that the scales were miscalibrated.


Calibration Note

M5Ve indicates an active flare star, which fully accounts for the orbital-only settlement pattern. Through_route topology at hop 6 is a natural extension of Miryang's position as a Korean corridor hub; Yeongwol represents the corridor continuing outward rather than terminating. The second adjacent connection (GJ 124, Hạ Long — hop 7) is the outbound gate, consistent with Yeongwol's function as the last established waypoint before the corridor's deeper Vietnamese-heritage systems.
