Implements the Phase 3 atlas content generator per D-191 §3, §8, and §9.
Pipeline per body (terrain-aware, deterministic per seed + body):
1. Simulate terrain via planet_simulation.simulate().
2. Analyse continents (flood-fill), habitability (temp/moisture/slope +
coastal bonus), river mouths, and a terrain A* cost grid.
3. Place cities sequentially — capital first (habitability + river-mouth
bias), then corridor growth via multi-source Dijkstra, quadrant-spread
penalty after 2 cities in a quadrant, port-on-new-continent bonus at
cities 3–4. ±25% noise for seed variation.
4. Generate roads and railroads as an MST over city positions, with
A* paths on the terrain cost grid (rail follows roads where possible).
5. Place a transit POI at the capital (15% chance to scatter to a
secondary city).
Output (canonical markers.json schema, pixel space per D-191 §8):
- cities: {id, name, kind, center:[r,c], population}
- roads: {id, name, kind, path:[[r,c],...]}
- railroads: {id, name, kind, path:[[r,c],...]}
- pois: {id, name, kind, center:[r,c]}
- existing rivers/oceans/mountain_ranges preserved untouched.
City names are left empty for gemma_naming.py (#833). Body population is
split across cities with geometric decay (capital ~50%, each subsequent
city half the previous). The 6 hand-authored bodies (Lendel, Edict,
Vuurkloof, Røros, Cairnside, Estrade) are detected by existing
`cities` and skipped for regeneration; their markers are still synced
to the DB index below.
Atlas index in systems.db (new):
- atlas_body_grids, atlas_cities, atlas_roads, atlas_railroads,
atlas_pois, atlas_rivers, atlas_oceans, atlas_mountain_ranges
- Scalar metadata mirror of every markers.json — the implant atlas app
and development queries can lookup cities/POIs/features without
scanning 267 JSON files. Polyline geometry stays in the markers.json
files next to the heightmaps (used by the renderer); the DB only
stores filterable scalar fields plus `point_count` as a length proxy.
- Schema lives in server/data/systems-schema.sql; generate_atlas.py
mirrors the CREATE TABLE IF NOT EXISTS block so it runs against any
DB state (matches the economy-db importer pattern).
- Populated and refreshed on every run. Each body's rows are deleted
and reinserted deterministically — no stale state.
Also fixes a pre-existing WIP bug in the quadrant-saturation penalty
loop (a stray outer `for r in range(GRID_H)` with unreachable breaks
meant only the NW quadrant was ever checked).
Runtime: 280s for all 267 inhabited bodies on a single core. 265 bodies
updated this run, 6 hand-authored bodies synced to DB without
regeneration.
Atlas index after run:
atlas_cities 329 (15 hand-authored + 314 awaiting #833)
atlas_roads 46
atlas_railroads 44
atlas_pois 287
atlas_rivers 2034
atlas_oceans 696
atlas_mountain_ranges 1953
atlas_body_grids 267
Full regeneration of ~2,600 bodies with:
- Correct atmosphere rim colors for extended planet classes
- Clean headings and profile tables (no underscores)
- Boreal/tropical cloud coverage at correct ranges
- Gas giants without meaningless terrain fields
- All heightmaps at 1024x512

Scaffolded index.md, globe.png (512x512), heightmap.png (1024x512),
terrain.npz, and markers.json for ~2600 celestial bodies across the
Settled Reach. Heightmaps render at native simulation resolution.

"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.

Horizon stations not renamed. No corridor reassignments.
Conservative: systems with existing identity untouched.

Rename to avoid association with Traveller RPG species name.
GJ catalog ID unchanged. Updates system page, Drifter's Guide,
cross-references from Kensho and Renaissance, catalog, index,
and cultural migration design doc.

Write 21 new Guide entries for all core systems (24 total with the 3
existing), plus the Guide index with preface and 6 sector chapter files
(core complete, cardinal stubs in Guide voice).
In-universe publication by Adams & Ford Publishing Syndicate. Voice
inspired by Douglas Adams — homage, not pastiche.

Gate builders don't place two horizon stations in one star system.
Binary pairs (A/B components of same physical star) split to
independent stars. Each "move" system keeps its connections and
content, only the host star changes.
Migrations:
- GJ 559A (Rigil Kentaurus) -> GJ 768 (Altair) — rewritten for new star
- GJ 725A (Renaissance) -> GJ 251
- GJ 820A -> GJ 3877 (Tessera — compact/records world)
- GJ 570B -> GJ 1156
- GJ 783B -> GJ 299
- GJ 663B (Guniibuu B) -> GJ 1286 (Kensho — university world)
- GJ 338A -> GJ 4053
- GJ 280B -> GJ 3991
- GJ 15B -> GJ 4274
New system names and roles assigned:
- Tessera: founding compact + institutional records
- Kensho: university world, largest Institute presence
- Vargr: mining (DSMC, MVG/GC minority stakes)
- Parallax: media world (was Procyon)
- Lu Ban: failed corp / mixed industrial (was Groombridge 34)
- Altair: southern gateway (was Rigil Kentaurus)
- Keid: garden world / ecological reservation
- Ross 128: ocean world (fishing, research, tourism)
Also adds docs/design/gj-catalog-full.json (3801 GJ entries from
HYG v4.2) for future star assignment.
