- Galaxy shrunk to 200 systems (data/galaxy.json) — always fully known,
generation ~15 ms; roster/content two-level design unchanged.
- Object composition replaces planetCount (data/systems.json → objectCount):
10% barren (jump-gate-only), else 2/3/4/5 objects (planets + free-space
stations) at 15/30/30/15. One unified roll (rollSystemComposition) shared
by the content generator and the frame pass.
- Barren systems: no planets, no stations, no asteroid clusters; their
single gate sits on the star→destination ray at barrenDistance (8192 px).
Strong connectivity keeps them reachable.
- Jump gates are DORMANT by default: every gate record carries
active:false, the entity renders dim with a still field. Activation is
the seam for the tether mechanic (an activated gate anchors a level-1
tether). data/gates.json gains barrenDistance.
- Frame diversity (js/galaxy/PlanetFrames.js): one galaxy-wide pass spreads
(class, frame) across the galaxy — fixed spatial order, least-used face
among already-assigned nearest stars, seeded tie-breaks. Stamps
planet.frame + content.homeFrame, read by GameScene.
- Tests: dev/frames.test.mjs added; jumps/galaxy/discovery/jumpgate/asteroids
suites updated to the new rules (composition buckets, barren gates,
active flags, frame determinism/spread, 5-object max, index clamps).
- Docs (README, PROJECT_NOTES) and stale 40k references updated.
- Generate 4–8 rock groups per system with seeded placement, spacing, and slow tumble/drift motion driven by data/asteroids.json
- Add AsteroidCluster entity (Phaser container) with halo, dust motes, per-rock spins, and ship keep-out collision reusing Planet.resolve
- Integrate clusters into GameScene: load spritesheet, constrain ship post-physics, include in click-to-fly/autopilot/discovery/compass
- Synthesise unique cluster names via NameGenerator.asteroid (syllables + field suffix)
- Add dev test suite and ?seed= param for deterministic galaxy generation
Planets and space stations were previously made by stitching a root word to
a kind noun ("Kest Skyspire", "New Natick IV"), which read like labels, not
names. They now draw from deep, hand-picked name BANKS in data/naming.json:
- banks.planet — colonial "New Denver"/"Port Tucson" worlds mixed with
alien "Klaxoria"/"Vexithunhal" worlds (269 names).
- banks.station — official designations ("Deep Space SC-145", "Nav Relay
V-77") mixed with smuggler hangouts ("Hell's Hideout",
"The Rusty Anchor") (165 names).
Assignment is a seeded shuffle of the whole bank (NameGenerator.planetDeck /
stationDeck), dealt out per-system in order, so a system never repeats a
name until the pool is exhausted (impossible at these sizes). The decks come
from dedicated Rng.derive(...) streams, keeping generation order-independent
(lazy === eager). Stars and the galaxy still synthesize from syllable pools
(unbounded), and the home world keeps its configured name.

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.
