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

Meridian is in the extraction phase of settlement and has not yet developed the agricultural capacity to feed itself. The habitable body — one, with conditions that the colonial assessment rated as garden-grade — is under active conversion: the first agricultural operations are established, the hydroponics infrastructure is ahead of schedule by the standards of comparable wave_5 settlements, and the system's colonial development committee has filed projections showing food self-sufficiency within fifteen years. Whether those projections hold depends on investment continuity, which depends on the governance situation, which has not been stable enough to evaluate with confidence.

The import dependency is serviced entirely through two gates. One connects to Struve — another wave_5 settlement, similarly early-stage, also importing food, unable to serve as supply source in any meaningful quantity. The other connects to Groombridge, the financial capital of the inner orbit, a system that does not export food but does export instruments of credit. The practical consequence is that Meridian's food supply chain runs through Groombridge's gate, which means it runs through Groombridge's freight infrastructure, which means it runs through agreements negotiated in Groombridge's institutional framework. The financial houses at Groombridge did not design this arrangement. They have found it useful.

The extraction economy is genuine and growing. Mineral surveys of the outer belt systems have returned results that, by the assessments of Syndic-affiliated geological firms, represent significant long-term value. The question of who captures that value — the extraction consortia that arrived in the first wave of settlement, the colonial government structure that does not yet exist in stable form, the financial instruments that Groombridge houses have already begun structuring around projected output — is the economic argument underlying every political contest in the system. The resources are real. The ownership is not settled.

Faction Notes

Meridian's political situation is younger than it appears. Mass settlement is recent enough that the founding disputes — who holds which land tenure, which extraction site was claimed under what provisional authority, which governance framework the first-movers negotiated before the slower-movers arrived — are still live cases rather than historical fact. The system does not have a contested government. It has competing frameworks for determining what a government would be, and no institutional mechanism yet capable of selecting between them.

The extraction consortia occupy the most advantageous position. They arrived first, established operations, and built the physical infrastructure that subsequent settlers depend on: transit facilities, early housing, the power generation plants that the agricultural operations run on. Their claim is not legal in the formal colonial charter sense — the charter process is ongoing at the Assembly's jurisdictional intake office — but it is the claim backed by operational fact. Displacing the first-mover extractors would require contesting what they built, which is what the new settlement depends on. The consortia understand this. They have been patient in the governance negotiations in the specific way that patience is available to parties who control the infrastructure everyone else needs.

A substantial migration wave — the largest cohort in Meridian's settlement history, arriving in the last decade — came under recruitment terms that several Syndic-adjacent combines circulated through wave_5 activation networks. These are the settlers who constitute the system's primary labor force, who hold the strongest Guardian of Autonomy sympathies, and who arrived under contractual terms that the Commission's field office at Groombridge has now flagged for review. The review has been open for three years. It has produced no enforcement action.

The financial houses at Groombridge are present at Meridian not as a governance actor but as a service layer: they provide the credit instruments that fund extraction operations, the freight insurance that covers the import supply chain, the escrow services that hold contested land-tenure deposits while the charter process runs. This is standard commercial activity, and it is conducted under standard terms from Groombridge's perspective. From Meridian's perspective it means that the system's most significant financial relationships are managed by institutions one gate hop away, in a system where the interests of extraction capital and established institutional practice are well-aligned and the interests of recently arrived settlers are less legible. The financial houses do not have a preferred outcome in Meridian's governance contest. They have preferred counterparties, and the extraction consortia are easier to work with than a fragmented settler coalition with no unified representative structure.

The Lattice Commission maintains a field office at Meridian's primary transit facility. Its mandate here is, as at Struve, preliminary — though Meridian's assessment was filed more recently and has not yet accumulated the years of procedural delay that Struve's has. What the Commission's field team has produced is a detailed record of the governance contest's factual terrain: who holds what, under which provisional authority, with what documentation. The Commission does not adjudicate charter disputes. It certifies conditions. The conditions at Meridian, accurately certified, describe a system in which the institutional advantage systematically favors the parties with the most prior operational history — which is to say, the parties that arrived before the Commission got there.

Silence Topic

What Meridian does not discuss: that the system's position on the map was not an accident of gate topology but a selection.

The Reach's wave_5 activation pattern is, in the Assembly's public framing, a natural consequence of horizon stations activating on schedules that human institutions cannot predict or influence. New apertures open; the Assembly's charter process responds; settlers move. This framing is accurate as far as it goes. It does not address the prior question of which systems are positioned to benefit when a wave_5 activation creates a new corridor.

Meridian sits between Struve and Groombridge. Struve's second aperture activated forty years ago; that activation created the Struve-Meridian-Groombridge corridor as a viable route where previously the topology had been different. The financial houses at Groombridge — who maintain the most complete interstellar freight route models in the Reach, and who had been modeling the potential value of wave_5 activations in the systems adjacent to the Gateway cluster for two decades before the Struve event — were positioned to extend credit to Meridian's first extraction operations within months of the charter intake opening. The recruitment networks that brought Meridian's labor wave arrived through logistics channels that Groombridge-affiliated combines had been building out for the Struve corridor before Meridian's settlement was formally authorized.

None of this is improper. The financial houses do not control gate activations. They anticipated one, correctly, and positioned capital accordingly. The settlers who arrived under the terms that the Commission's field office has flagged for review were not deceived about the physical conditions they would find. What they were not told — because the parties that recruited them had no obligation to tell them — is that the system they were moving to had been identified as a target for capital deployment before it was identified as a destination for settlers, and that the terms available to them had been structured accordingly.

Narrative Hook

The money was already in place when the first settlers arrived; what looks like a boomtown is the visible surface of an investment thesis that Groombridge's financial houses wrote before the gate opened.

Calibration Note

settlement_wave: wave_5 in sector: core is structurally parallel to Struve and requires the same justification: core-sector wave_5 systems are not geographically remote but temporally recent, their settlement enabled by horizon station activations that occurred within the past forty years. Meridian's position in the core sector reflects gate-hop distance from Gateway, not settlement history. The habitable body has existed for the same timeframe as every other body in the inner orbit. Human occupation began recently because the gate connection did not exist before Struve's second aperture opened the corridor.

aperture_count: 2 with topology: loop_member at hop_distance: 2 from Gateway produces a connectivity profile that looks underpowered for the system's role as a boomtown. Two gates, in the context of Meridian's situation, are a structural constraint that concentrates leverage: everything flows through Struve or Groombridge, and those two systems are therefore Meridian's entire external relationship. The hub topology that a 7-aperture station like Cairn enjoys — multiple corridors, multiple dependencies distributed across multiple neighbors — is not available here. Meridian's exposure is bilateral. Both counterparties are aware of this. One of them is a financial capital.

atmospheric_tone: frontier_energy — not profiled in detail at the stub level, but derivable from the settlement conditions — accurately describes a system where the physical work of building something is underway and the outcome remains genuinely undetermined. This is not the performed normalcy of a system that has learned to manage its tensions quietly. The disputes at Meridian are current, loud, and conducted in the open because the institutional framework that would channel them into procedural form has not yet been established. The energy is real. Whether it resolves into something the settlers who produced it will benefit from is the open question.
