- Replace producer/demand class pricing with strict 1:1 origin assignment;
each settled system sells exactly its signature good at a discounted origin
price, and the catalog remainder becomes a hub pool resold by stations/capitals
- Make banded hop distance the dominant sell-price factor (x1.0 to x7.0),
with planet-type demand as a secondary +10% modifier, and cap every shop's
sell price at its own buy price to eliminate the v1 infinite-credit loop
- Add Stock.js for the time-gated daily batch (6 units per origin per wall-clock
day) — the economy's only stateful piece; wire it through GameScene,
SaveData capture/restore/reset, and the shop UI stepper clamp + SOLD OUT strip
- Update Economy.js with assignOrigins pass, new buyPrice/sellPrice/shopFor
logic, tradePreview stock-cap backstop (buyback exempt), and distanceFactor
- Rework shop UI: BuyList shows "N left"/"SOLD OUT" per batch-limited row and
clamps the stepper; ScoutPanel shows MADE IN (origin system) instead of GROWN ON;
ShopView wires stockRemaining/stockCapsFor/spendStock into preview and confirm
- Update all dev tests (economy, cargo, shop-ui, saves) to assert model v2
invariants including the anti-loop sweep, batch clamp/backstop, and save round-trip
- Waypoints were comms-only beacons with no landing or trade; a second
deep-space station is a more useful destination in their place
- The old waypoint chance in systems.json becomes
deepSpaceStation.second, so a system can roll 0–2 stations
- StationFrames now assigns a distinct sprite variant per station
(Galaxy.stationFrames is id → [frame, …]) and a two-station system
always wears two different variants
- Rename the route-gate pulse from "destination's waypoint" to
"route's next stop" so the term no longer refers to a removed kind
- New `js/galaxy/PlanetClasses.js` deals non-home planets from one shared deck so every class lands at ~1/N of the galaxy while star type still flavors local systems
- Config knob `systems.planetClassBalance` (enabled + bias) blends an even split with the star-mix preference; bias 0 = exactly even, 1 = old free preference
- Stamp `galaxy.planetClasses` is read back by content generator, frame pass, economy, and type preview so lazy/eager generation agree
- `rollSystemComposition` accepts optional stamped classes; falls back to per-type weighted draws when balance is off or stamp absent
- Fix arid-surface video path in landing.json (was pointing at ice surface)
- Update shop-ui and trade-scout tests to pick rows the current system actually wants, and handle home-world exit resolution
The Shop button on the deck is now always live — the shop sub-bar opens on every world. The "Special Delivery" capital-landing witness now gates only the shop's Buy/Sell tab (ShopView reads GameScene.isTradeUnlocked, which replaces isShopUnlocked), so trading stays dark until the player lands on the neutral capital while the rest of the shop UI is reachable everywhere.
- Rename GameScene.isShopUnlocked → isTradeUnlocked and update all references (SaveData, SurfaceScene, quests.json comments)
- Remove the deck-slot enable guard in SurfaceScene.toggleShop / setBarLocked; the slot now re-arms with the rest of the deck
- Add ShopView.isTradeUnlocked + gate checks in setTab / _onTabTap; gray the Buy/Sell tab via _refreshTabs until the gate lifts
- Update dev probes (scout-*, shop-*) to lift gs.story.capitalLanded so the trade panel is reachable
- Extend shop-ui.test.mjs with a TRADE GATE case covering closed/lifted states
- New main quest granted after claiming "Leaving the Nest": land at the neutral capital (the bar), upgrade cargo bays, then deliver the sealed package to the home world.
- Introduce a non-tradeable `special-package` good (sheet frame 114) that no shop stocks or buys back; `Economy.isTradeable` filters it out of every floor and the sell grid refuses to queue it.
- Record story witnesses (`capitalLanded`, `launchedFromCapital`, `lastLandedWorld`, `delivered`) in a registry-backed ledger, persisted via SaveData so progress survives load and reset clears it.
- Gate the surface shop behind the capital landing: deck slot disabled and `toggleShop` refuses until `isShopUnlocked`.
- On capital departure, set the destination back to the home world so the compass marks the delivery leg; delivery proof is monotonic once recorded.
- Surface console note announces the package handoff when it first lands in the hold.
- Extend economy and quest test suites to cover the new check types, non-tradeable exclusion, unlock chain, and save/load of the story ledger.
- Ensure each class's gemstone (tier 3–4 producer good) always appears on the shop floor, swapping into the least-important slot when at max stock to preserve size and avoid duplicates.
- Add a test sweeping every system/class to verify the world's "jewel" is present, produced, and premium in all shops.
- Introduce CargoHold (pure class) as the ship's trade-goods carrier: fixed bays, one good each, capacity = unlocked bays, save/restore round-trip. Ship.cargo + setCargoHold/cargoRoom wired into stats.
- Add three credit-costed cargo builds (cargo-bay-8/12/16) that expand the hold 4→8→12→16 (MAX wins). BuildWindow affordability now covers both minerals and credits; GameScene.beginBuild debits credit lines and _applyCargoUpgrade expands the hold on completion.
- Add tradePreview/resultingCargo to Economy.js as the shop's pure calculator: sell/buy pricing, net credits, the two caps (can't go negative, end hold fits capacity), and atomic sell-to-free-room-for-buy.
- New ShopView + TradeGrid compose the buy/sell screen over the shop clip: SELL grid of cargo bays (tap to check), BUY grid with quantity steppers, live NET preview, Confirm/Clear, and a session-local Buyback tab (neutral undo at the sale price, locked until a sale). Wired into SurfaceScene's SHOP button.
- data/shopui.json drives the shop layout/animation knobs; economy.json gains cargo.maxSlots (16-slot grid); ship.json base cargoHold drops to 4 unlocked bays.
- Headless tests: dev/cargo.test.mjs (hold rules + trade preview caps), dev/shop-ui.test.mjs (construct, sell, buy, caps, buyback, clear), plus updated builds/ship-behavior suites; phaser-stub gains Geom.Rectangle for the hitArea path.
- New Economy.js price/stock engine: deterministic buy/sell prices based on
producer/demand classes and hop distance (regional availability model)
- Goods catalog (114 goods, 9 categories) with spritesheet mapping and
per-class producer/demand roles
- Credits state on Ship (add/spend/set/canAfford), save/restore support,
and upper-right HUD stacked above the minerals readout
- Quest reward payout now supports credits alongside minerals
- cargoHold reduced to 4 units for initial play balance
- Economy generation pass in Galaxy.js computes classBySystem and
producerHops via multi-source BFS over the jump network
- dev/economy.test.mjs validates determinism, fixed prices, trade loop
profitability, distance scaling, shop floor composition, and icon mapping
- docs/ECONOMY.md: full design doc covering pricing model, gemstone system,
and locked decisions
