- ON DELETE CASCADE added to every atlas_* foreign key (atlas_body_grids,
atlas_cities, atlas_roads, atlas_railroads, atlas_pois, atlas_rivers,
atlas_oceans, atlas_mountain_ranges). Previously, deleting a body from
the bodies table or NULL-ing its terrain_reference would leave orphan
atlas rows forever — sync_markers_to_db only cleans up for bodies it
re-processes. The existing atlas tables in systems.db were dropped and
recreated with the new constraint; FK list now reports CASCADE.
- Atlas DDL deduplicated. systems-schema.sql is now the single source of
truth, bracketed by `-- BEGIN ATLAS INDEX` / `-- END ATLAS INDEX`
markers. generate_atlas.py reads that block via `_load_atlas_schema()`
and applies it at runtime, so there is no second copy of the DDL to
keep in sync. Adding a column requires one edit, not two.
- Uniqueness guard on city coordinates. `_enforce_unique_city_coords`
runs at the end of `place_cities` and deterministically perturbs any
duplicate (row, col) via a fixed spiral walk to the first free
walkable land cell. Rare in practice but the MST collapses to a
zero-distance edge otherwise, producing an empty A* path and silently
dropping the road.
- Grid header validation. `load_markers` now raises `AtlasGridMismatch`
if the loaded `grid: {w, h}` header does not match `GRID_W`/`GRID_H`.
Both the incremental-skip path and the regenerate path route through
this loader, so a hand-authored template shipping a different grid
size fails loud with a per-body error rather than silently producing
half-scale coordinates.
- Unused `seed_rng` parameter removed from `_analyse_terrain`. The
function is RNG-free (continent flood-fill, habitability scoring,
river-mouth dedup, cost grid — all pure functions of terrain). The
false API contract made it look like terrain analysis consumed RNG
state and had to be sequenced with downstream RNG use.
- `_score_capital_sites` river-mouth bonus now builds one sparse
accumulator with all mouth points set at once and runs a single
`gaussian_filter` call, instead of O(n_mouths) filter calls over
single-point images.
- `binary_dilation(analysis["land_mask"] == False)` replaced with the
idiomatic `~analysis["land_mask"]`, matching the convention used
elsewhere in the file.
- `atlas-generate` Makefile target now guards on
`SELECT COUNT(*) FROM bodies WHERE terrain_reference IS NOT NULL`.
On a fresh DB that count is 0 and the generator previously exited
"success" after processing zero bodies. The target now fails loud
with a pointer to `populate_terrain_reference.py`.
- `main.rs` SimRng defensive re-insertion gains a long comment
explaining the exact plugin-ordering hazard it guards against, so
future readers don't treat the line as dead code. Tied to #826.
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
Adds tooling/planet-gen/populate_terrain_reference.py and runs it against
systems.db. Resolves each body's expected wiki heightmap path (repo-root
relative) and writes it into bodies.terrain_reference. Missing heightmaps
are logged for remediation.
Result: 2380/3240 bodies populated, 860 still missing heightmaps. This
unblocks generate_atlas.py (#832) for every body that has a heightmap.
Custom pipeline for GJ-0 (Sol) that imports real NASA/USGS
planetary data instead of procedural generation. Produces the
same output format (heightmap.png, globe.png, markers.json).
Real data bodies:
- Earth: ETOPO2022 elevation + WorldClim climate + 14 rivers
- Mars: MOLA DEM + ferric biome classes + terraformed water
- Luna: LOLA DEM + lunar biome palette
Procedural fallback for Mercury, Venus, Phobos, Deimos.
Synthetic elevation from albedo for Io, Europa, Ganymede,
Callisto, Titan, Enceladus. Gas giants use existing renderer.
New biome classes 34-36 (ferric_dust/highland/lowland) for
Mars iron oxide surface. Earth features: 50 cities (smart
scatter by continent), 15 named rivers, oceans, mountains.

arctan2(hz, hx) wrapped longitude counter-clockwise, mirroring
east and west on the globe. Changed to arctan2(hx, hz) which
increases eastward (right on screen). Added +0.5 offset to center
the view on 0° longitude, keeping the dateline seam on the back.

1. Add 5 extended atmosphere colors to biomes.toml (globe renderer reads
from toml, not body_def) — cold_arid, hot_arid, tropical, boreal,
temperate_terminator. Remove dead martian entry. Slightly differentiate
colors from base classes.
2. Fix profile table raw identifiers — apply .replace('_', ' ') to class
field in wiki body pages.
3. Fix legend text overflow — truncate labels with ellipsis when step
size is too narrow for full text.
4. Fix title panel underscores — use .replace('_', ' ') instead of
.replace('_ringed', '').

1. Fix pclass.title() underscore bug in scaffold headings (216+ files)
2. Add 5 extended classes to batch.py valid_classes set
3. Add atmosphere rim colors for cold_arid/hot_arid/tropical/boreal/temperate_terminator
4. Add cloud/tilt ranges for extended classes (boreal 55-75%, tropical 60-80%)
5. Fix legend overflow at 1024px + deduplicate rainforest labels
6. Move _check_habitability() inside loop (was only checking last body)
7. Preserve gas_giant_ringed distinction in profile table
8. Drop meaningless terrain fields from gas giant frontmatter
9. Update stale docstrings/comments for 1024x512 default
10. Add infernal ring color
All lookup tables (CLASS_TILT, CLASS_CLOUD, CLASS_POLAR_ICE, CLASS_GEOTHERMAL,
CLASS_OBLATENESS, atmo_colors, tectonic_map, substrate_map) now include the
5 extended planet classes. Body content requires full regeneration.

The atomic .tmp→rename pattern caused silent FileNotFoundError on some
bodies. Removed in favour of direct writes — resume logic already handles
interrupted runs. Fixed --heightmap-size CLI flag which was silently
ignored due to Python default parameter binding. Changed default heightmap
resolution from 4096x2048 to 1024x512 (native simulation grid — no
information gain from upscaling).

"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.
