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.

GJ 117 is an empty through_route at the edge of the east_reach — two apertures, one toward GJ 434 and through it toward Taishan, one toward GJ 211 in the deep corridor. The M-dwarf is a dim red primary with a stable habitable zone and no obvious settlement barrier. The surveys were done. Nothing was wrong. No one came.

The timing was unfavorable. The east_reach push extended this corridor during an era of confident expansion, but the systems that might have seeded settlement here had their populations absorbed into closer, more connected communities during the Secession period's economic contraction. GJ 117 remained on the charts as an open route rather than a destination.

At hop 7, it sees genuine transit traffic — vessels moving between the east_reach's outer corridors and the deep frontier systems beyond GJ 211. Most of that traffic passes through without slowing. The in-system passage between apertures is clean and unremarkable. Navigation broadcasts from the automated relay indicate no anomalies. The relay's most recent log entry is current; someone, somewhere, is still maintaining it — possibly the Commission through Taishan, possibly on automated schedule with human oversight in name only.

Supply Dependency

None. No population, no active resource extraction.

Faction Notes

No faction presence. Apertures and relay registered to Commission infrastructure. Maintenance accountability sits with the east_reach administrative structure rooted at the corridor's junction systems.

Silence Topic

Not applicable — no population to keep silence.

Narrative Hook

Transit logs at GJ 117 show a consistent but unexplained pattern: a vessel identifying as a Commission survey ship has been transiting the system once every three months, on a precise schedule, for at least the past seven years. No survey program matching the identifier exists in the public register.

Calibration Note

Unsettled through_route at hop 7 with no settlement barrier is a mild anomaly; justified by historical timing rather than physical obstacle. The transit connection between GJ 434 and GJ 211 makes it structurally significant despite being empty.

The outer planet Doi Kaeo (Thai: 'crystal peak') was named by a Thai-heritage survey team that passed through GJ 117 during the east_reach corridor-mapping runs — one of several teams who left Thai place-names on unsettled bodies along the route. Survey teams name what they find; the names outlast the teams. Doi Kaeo has been on the charts under that name for over two hundred years without anyone living there to use it.
