The galaxy was settled long before the player arrives. Systems now
host colonies on habitable worlds, mining stations over resource
worlds, cloud bases riding gas giants, stations adrift in open
space, and beacons — or report "charted · unclaimed" when empty.
- data/settlements.json: the shared kind vocabulary (label, theme,
population range, anchor type); add a kind = JSON + naming pool.
- Per-archetype rates in data/systems.json (chance + required
planet class) and a core→rim density gradient in data/galaxy.json
(falloff/floor), keyed off each record's new rNorm.
- Draws stay in a stable order on the system's own Rng stream, so
lazy and eager generation still produce identical content.
- Every settlement keeps owner: null, a reserved seam for the
factions/pirates that will claim them later.
- NameGenerator.station() names from anchor + kind ("Kest Skyspire").
- SystemReport.js is a pure, testable formatter (dossier lines,
"charted · unclaimed" for empty); GameScene's HUD renders it and
Node tests cover structure, mix, gradient, naming, lazy === eager.
- Main menu Galaxy Seed panel: displayed, editable, rerollable; the menu
previews what the seed builds (galaxy name, scale, archetypes) before
committing. Same seed always generates the same galaxy.
- js/galaxy/Galaxy.js: seeded roster of 40k systems (disk + core + spiral
arms, type weights, radial bands) with spatial hash for neighbor queries;
contents generated lazily on arrival — identical to eager generateAll()
because each system draws from Rng.derive(seed, 'system', id).
- js/galaxy/SystemGenerator.js + data/systems.json: six themed archetypes
whose attributes (star classes, planet count spread, class weights,
moons, belts, habitability, hazard) steer content generation.
- data/galaxy.json layout/distribution knobs, incl. distribution.rules[]
hook for future proximity/clustering rules; data/naming.json name pools.
- GameScene: current system name/identity HUD (lazy content generation
on arrival); dev boot without a menu falls back to a dev galaxy.
- dev/galaxy.test.mjs: determinism, distribution, bands, lazy==eager,
neighbor brute-force checks (40k roster in ~70ms).
- Docs: world model, determinism rules, roadmap update.
- Boot the game from a static server with no build step (Phaser 4 vendored in lib/)
- Main menu (New Game button) and GameScene where clicking makes the ship fly there
- All tunables live in data/*.json (game/menu/ship), loaded via manifest + Config singleton
- Ship behavior driven by arcade physics (thrust, drag, maxSpeed, arrival) with a Node test harness (dev/ship-behavior.test.mjs) and a dev smoke page that boots straight into GameScene
- Project conventions documented in docs/PROJECT_NOTES.md; README rewritten to describe layout, run instructions, and dev tools
