- 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.
Blocking PR #129 items 1, 2 (plus polish 16 and 17):
- D-191 §8 prose rewritten to match the code. The previous amendment said
positions were `{x, y}` objects against a "typically 1024 × 512" grid,
but the generator, the six hand-authored templates, and all 2394
procedural seed files ship `[row, col]` integer arrays against a
`{"w": 512, "h": 256}` grid. The decision doc is now aligned with
reality: positions are `[row, col]`, the storage grid is 512 × 256,
and the row-first ordering is called out explicitly so readers can
cross-reference NumPy/flood-fill/A*/cost-grid conventions.
- §8 now follows the D-094 amendment pattern. The superseded 2026-04-10
prose is preserved verbatim as "Original (superseded)" with a dated
Amendment block on top — future readers can see what changed and why
instead of silently losing the history.
- brands.toml header gains a short Phase 2 boundary note. The 4 anchor
brands come from D-189 §5; the additional ~23 brands from D-189 §11
are deliberately deferred to Phase 3 — Phase 2 only needs the demand-
node plumbing and V-B01..V-B06 validation exercised end-to-end.
- systems-schema.sql `bodies.terrain_reference` comment now pins the
repo-root-relative path convention (wiki/star-systems/<slug>/bodies/
<body_id>/heightmap.png) so the three downstream pipelines (populate,
atlas generator, client loader) share a documented contract instead
of drifting against an unwritten convention.
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 the brand layer per D-189 §5:
- Schema: brand_products, brand_inputs, system_fiscal, corp_financial_state,
corp_lifecycle_events (+ 5 indexes).
- Importer: reads wiki/economics/corporations/brands.toml, populates the
new tables, validates V-B01–V-B05 structural rules, and derives
system_fiscal for inhabited systems.
- Data: 8 brand_products, 16 brand_inputs, 301 system_fiscal rows.
Brand products are demand nodes — they consume commodities; they are not
commodities themselves (D-185). Depends on copy PR #127 for the corp
records referenced by brands.toml.
Extends systems.db schema with gate_links, commodities, production_chains,
chain_inputs, corp_presence, and currency_zones tables required for the
Phase 2 economics layer.

Add 5 new tables: gate_links (668 bidirectional edges from star-map.json),
commodities (36 types from commodities.toml), production_chains (21
Leontief recipes), chain_inputs (52 input requirements), corp_presence
(empty, populated by future pipeline). Add currency_zone column to
star_systems (D-172), archetype columns to corporations (D-175).
New import pipeline: tooling/economy-db/import_economics.py reads
TOML/JSON source files and populates the DB. Idempotent — safe to
rerun via `make economy-db`.

"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.

Schema: added orbital_period_days and rotation_period_hours to bodies
table. Proposal format now includes surface_gravity, orbital_period_days,
rotation_period_hours with sensible defaults per body type.
New sync-wiki command generates a Celestial Bodies section in wiki
pages from DB data. All 16 fields rendered including Year (d) and
Day (h). Re-authored Gateway (GJ 71) with full physics.

New tables for the celestial body hierarchy below system level:
- bodies: planets, moons, gas giants, asteroid belts, oort clouds
with physical properties, settlement data, and cultural overrides
- stations: orbital/surface facilities with type, population,
docking class, and gate infrastructure flag
Naming convention: GJ-{n}b (planet), GJ-{n}b-1 (moon),
GJ-{n}b-S1 (station), GJ-{n}-oort (oort cloud).
Self-referential parent_body_id for moon→planet relationships.

Replaces flat star_systems table with 7 normalized tables: star_systems,
system_gates (with hop_distance_from_gateway), system_history,
historical_events (1:N), system_economy, system_factions, system_culture.
Primary key is now the GJ astronomical ID (e.g., "GJ 244A") — S-number
identifiers removed entirely. The astronomical_id column is dropped as
redundant. Database moved to server/data/systems.db (ships with game).
10 core systems fully populated with structured data.
