- New shared audio voices: js/utils/Sfx.js (playSfxOn/stopSfxOn/sfxPlayingOn)
and js/utils/Music.js (loop voice + shuffle playlist), both with v4 guard
rails (cache.audio.has, stopByKey, isPlaying) so missing assets never throw.
- data/music.json: menu loop, shuffled deep-space soundtrack for GameScene,
and per-world surface loops keyed by planets.png frame; new mp3 assets in
assets/music/.
- data/sfx.json: add ui_hover/ui_click/ui_window/ui_close/mining_loop and a
dedicated scan track; wire UI components (buttons, panels, popups, save
vault) to the shared voice via scene.playSfx seam.
- GameScene: start/stop the shuffle on create/shutdown, stop both soundtrack
and mining hum on 'sleep' (landing launch+sleep) and resume on 'wake';
mining hum loops while beam is live and stops quietly on 'stopped'.
- SurfaceScene: preload and loop the world's track from landing through
takeoff; fix landing frame hand-off to pass sheetFrame instead of the
texture Frame object.
- MenuScene: preload SFX + menu music, start the menu hum in create, stop it
on the 'shutdown' event (v4 never calls shutdown() on transition).
- data/ship.json → stats: hullIntegrity/shields/cargoHold/mineralStorage,
exposed as ship.stats for future combat/trading/mining systems.
- Tests: dev/sfx.test.mjs and dev/music.test.mjs cover the shared voices,
guards, and data contracts; ship-behavior and system-hud tests extended
for base stats and the mining hum lifecycle.
- SaveManager: 10-slot localStorage bank (put/get/clear/list/export), corrupt-bank recovery, failed-write surfacing, bulk JSON export
- SaveData: captureState / prepareLoad / consumeRestore / resetRunState — seed + player state round-trip through a shared registry
- MenuSubBar: fold-up drawer off the deck's MENU button (Save Game / Load Game / Return to Main Menu) with animated open/close
- SavePanel: 10-slot pop-up in save or load mode; overwrite + load confirm dialogs; "download all" bulk export; toast feedback
- ConfirmOverlay: split-open confirm dialog for destructive actions
- SlotCard, Toast: per-slot cards and inline feedback strips
- MenuScene: Load Game button (grayed while bank is empty) opens the same panel in load mode
- GameScene: menu sub-bar + save panel wired into deck action, ESC handling, input blocking while modal, applyRestore on scene boot
- Tether HUD moved from above the MENU button to upper-right corner, stacking downward
- MenuButton: disabled (grayed) state and screenFixed option for scrolling-camera UI
- New SFX assets (ui-click, ui-hover) + updated existing FX; gasgiant planet image
- Dev tooling: cdp-firefox.mjs, wdshot.mjs (headless Firefox via geckodriver), saves-ui-test.html/.mjs (integration driver), saves.test.mjs (Node unit tests), system-hud test updates
