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.

Adds Bodies and Population rows to System Profile tables across all 301
star-system wiki pages. Adds Industries, Exports, and Imports economic
profile rows derived from systems.db economic_base + body type + topology.
Includes 9 body/station name changes from cultural diversity remediation.

Remove S-number from page headers and replace S-number references in
topology sections with GJ astronomical IDs. Headers now show
"**GJ XXX** | type | sector" instead of "**GJ XXX** | S-NNN | type | sector".

Wiki pages are the single source of truth for all per-system data.
Each stub contains all 68 columns in YAML frontmatter, pre-filled
from star-map.json for identity/infrastructure fields. Includes
Sol (S-000/GJ 0) and Van Maanen's Star (S-057/GJ 35) with Sova
station content.
