- CargoHold gains a parallel `costs` ledger (credits/unit actually paid, or null when no cost is on file), kept aligned across add/remove/set/capacity/dropFirstNot and serialized via toJSON/fromJSON
- ShopView stamps each bought bay with the trade's unit price so the console can compare exit prices against what was really paid
- ShipScreenModel/ShipWindow surface per-bay costs, a total-cost hold meta line, and a "PAID" chip + reference line in the bay manifest; bays with no cost read "NO COST" instead of inventing one
- GameScene passes the bay's recorded cost into scoutGood() so exit profits re-baseline against the purchase (falling back to the catalog value when absent), and restore/quest-handoff paths load null costs cleanly for legacy saves
- Adds arid-shop-02 video asset and updates cargo/saves/ship-window/shop-ui tests to cover the new ledger
- Wire the deck's SHIP slot to a full-screen ShipWindow (depth 80) following the Map/Quest window contract: bay-camera video panel with NO SIGNAL fallback, tab row, glitch/sweep dressing, ESC/scrim close, and exclusive open/close against research/map/quests/comms.
- Add data-driven Ship Status plate via pure js/ship/ShipScreenModel.js resolving every stat row from data/shipScreen.json (hull/shields live vs nominal, shield recharge, flight, fire rate/DPS, cargo/mineral holds) plus the combat level journey timeline that swaps to a CHOOSE YOUR CLASS door at level 5.
- Add Cargo Holds tab: bay grid with filled/empty/locked states, mineral aggregate bar, and a selected-bay manifest reusing TradeScout.scoutGood() for ranked exits in the buy/sell style.
- Register data/shipScreen.json in the manifest, preload ship.mp4 with skip-if-missing guard, and add dev test + screenshot harness (dev/ship-window.test.mjs, dev/ship-shot.{html,mjs}).
