description + price + stepper) instead of the 4×4 icon grid
Each stock good is now ONE WIDE ROW — the good's icon, its name + a
one-line description (the good's flavor), and the price + a −/qty/+
stepper on the right — the way the user wanted the shop list to read.
The stock (12–16 goods) outgrows the panel, so the list SCROLLS:
drag on the row area or the mouse wheel; rows outside the window are
clipped (row-based alpha clipping — this Phaser build has no
ScrollContainer/camera clip), and hidden rows' steppers are
non-interactive. The selection is data (goodId→qty), so stepping a
good works whether its row is on screen or not.
js/ui/shop/BuyList.js new — the scrollable BUY list (rows, drag +
wheel scroll, per-row steppers, flavor text)
js/ui/shop/TradeGrid.js SELL-only now — the BUY mode (steppers, stock
rendering, buy-selection data) is stripped;
one grid, one purpose
js/ui/shop/ShopView.js composes TradeGrid (SELL) + BuyList (BUY);
the BUY panel sizes itself to the SELL grid's
height (top- AND bottom-aligned)
data/shopui.json buyList row/typography knobs (name, desc,
price, row bg/border, selection accent)
dev/shop-ui.test.mjs BUY assertions rewritten for the list + a new
SCROLL section (scroll clamps, row clipping,
stepping off-screen rows)
dev/shop-shot.mjs BUY probe → the row's inline text (no tooltip)
docs/ECONOMY.md §12 the BUY bullet + mockup now describe the list
The BUY side's name + price used to live in a hover tooltip because a
grid cell is too small for text; a wide row carries them inline, so the
tooltip stays on the SELL side only. All headless suites green
(shop-ui, economy, cargo, builds, ship-behavior).
The pending trade's credit delta now sits at the right end of the
Buy/Sell + Buyback sub-bar, past a hairline divider — tabs AND the
credit math on one console, one glance apart (entry state dims it to
0 cr). The center column keeps Confirm/Clear (re-centered); the
buyback panel's Confirm moves up to sit just below its rows.
Knobs: data/shopui.json → preview (bar sizing, zeroColor, divider).
Docs: docs/ECONOMY.md §12 mockups + bullets follow the new layout.
Tests: dev/shop-ui.test.mjs asserts the bar's NET readout mirrors the
pending trade (+N cr while picking, 0 cr after Confirm).
- Shop now opens on the tab sub-bar only (shop video plays); clicking Buy/Sell reveals the trade panel — showcases the clip before the UI takes over.
- Tab bar and Confirm/Clear are now MenuButtons in a console-blue sub-bar that rests above the command deck, anchored to the deck's Shop button (MenuSubBar recipe), replacing the old top-of-screen custom buttons.
- Fix trade panel vertical placement: a Container's (x,y) is a pure translation of local space (verified via dev/cbox-test.html), so the grid position IS the panel top-left; setting it to topY + h/2 treated it as a centered origin and clipped bottom rows. Panel now anchors just under the HUD planet text via SurfaceScene.shopTopY().
- Parent TradeGrid plate/title to the grid container so they render above the shop video (scene-level depth-0 objects drew behind it in this build).
- Add dev probes (dev/cbox-test.html, dev/shop-shot.{html,mjs}) and update phaser-stub/test stubs for setSize/setBlendMode/rectangle; document entry state + sub-bar in docs/ECONOMY.md.
- 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

and locked decisions
