Stacked on #5348. The base branch of this PR is t3code/replace-game-sound-effects, not main. It merges after #5348; please review only the commits above that branch's head.

Rebased onto the mixer (base 1127dbc4e). #5348 now delivers the real AudioMixer, so three of this PR's commits were dropped because the base supplies them:

Dropped commit Superseded by
chore(audio): UserSettings audio methods per contract "Add per-channel audio volumes with read-through from the old two sliders"
refactor(audio): SoundManager follows settings.audio.* "Route audio through a per-channel mixer and fix the levels"
fix(audio): route the deprecated volume setters through setAudioVolume the same commit — the base delegates them already

The placeholder src/client/sound/AudioMixer.ts is gone; the tab now drives the real mixer.

Three edits to files #5348 owns — flagging them for that PR's author:

  1. src/client/sound/CuePlayer.ts gains an AudioControls hook (previewCue / isAudible) alongside the cue player. AudioMixer.ts imports howler at module top, so if the settings modal called audioMixer() directly it would drag howler into the import graph of every test that mounts a settings modal — exactly what the "reach the mixer through a hook" commit exists to prevent. Same pattern, one more capability.
  2. initAudioMixer() registers the mixer through setAudioControls(instance), and resetAudioMixerForTest() clears it.
  3. UserSettings.audioVolume() now clamps on read, not only on write. The legacy keys it reads through to were never bounded, so a stored settings.soundEffectsVolume of 1.5 reached the tab as 1.5 and rendered 150 on a 0–100 slider. Verified against the branch before fixing.
  4. UserSettings.muteOnBlur() defaults to off — muteOnBlur default flipped to off per Josh, 11 Sept. alertsWhenUnfocused stays on, since it only applies once mute-on-blur is turned on. The branch's own focus-defaults and focus-duck tests are updated to set it explicitly rather than lean on the default.

Accepted deviation: no Test button on Ambience. The design called for four; the tab ships three (Effects, Alerts, Interface). The base mixer's previewCue("ambience") deliberately resolves without playing — an ambience loop has no natural end, and it previews through the normal ambience path instead — so a button on that row would be enabled and silently do nothing.

Summary

Replaces the Audio tab's two volume sliders with the full mixer surface: six per-category volumes, a mute-on-blur pair, and a test cue per previewable category. The two sliders both defaulted to 0, which is why a fresh install was silent unless the player went looking for the setting; every category now has a sensible non-zero default.

The six categories

In render order, with their defaults:

Category Default Legacy source
Master 1.0
Music 0.5 settings.backgroundMusicVolume
Sound Effects 0.7 settings.soundEffectsVolume
Alerts & Notifications 0.8 settings.soundEffectsVolume
Ambience 0.4 settings.soundEffectsVolume
Interface 0.5 settings.soundEffectsVolume

Sliders show a bare 0–100 value (unit=""). Not a percentage and not dB: the position is squared into perceptual gain before it reaches the audio, so a percentage would be a lie.

Below them, Mute when the window is not focused (default on) and a dependent Keep alerts audible when unfocused (default on), indented and disabled while the first is off. disabled is new on setting-toggle and defaults to false, so no other tab changes.

Storage

Keys live under settings.audio.*. Each category reads through to its legacy key when its own is absent, and the legacy keys are left in place — this is a read-through, not a migration pass. A player who had set the old sliders keeps what they chose; everyone else gets the defaults above.

A stored 0 is respected, not treated as "unset". The only writer is a slider drag, so 0 is always a deliberate choice. Un-muting someone who deliberately muted is the worse error. Values are clamped to [0,1] on read as well as on write, because the legacy keys were never bounded and a stored "1.5" would otherwise render as 150.

Driving the real mixer

The tab reaches the mixer only through CuePlayer's two seams — playCue for the slider tick and audioControls() for the test buttons — so no UI test pays for howler.

  • Test buttons call previewCue(category) and stay disabled until that cue resolves. A cue whose asset fails to load or play settles neither end nor stop in Howler, so the preview races a 10 s ceiling: the worst case is one dead press, not a button that is dead for the life of the page.
  • Buttons are hidden entirely, not disabled-with-hint, until audioControls() is non-null — before initAudioMixer runs, the hint "turn this channel up" would be wrong advice.
  • The slider tick is the base's, not a second one: the handler calls the existing playSliderTick() (playCue("slider"), 150 ms rate limit). Tests cover one tick per drag and, importantly, none on a programmatic value set.

Deleted: the volume bus events

SetBackgroundMusicVolumeEvent and SetSoundEffectsVolumeEvent are gone, along with SoundManager's subscriptions, UserSettingModal's eventBus? property and both emit sites, and GameRenderer's wiring of it.

Volume now travels as a UserSettings change: SoundManager reads audioVolume("music"/"effects") at construction and follows USER_SETTINGS_CHANGED_EVENT for those keys on globalThis, unsubscribing in dispose().

This is what fixes the two-EventBus bug. The home page has no game EventBus, so the menu theme could never hear the music slider — the modal emitted onto a bus nothing there was listening to. MenuMusic now follows the same setting and changes volume live.

Commit layout

chore(audio): UserSettings audio methods per contract is deliberately droppable: it is purely additive and should be dropped on rebase if #5348 supplies the same methods. Likewise refactor(audio): SoundManager follows settings.audio.* is kept minimal so it drops cleanly when the mixer supersedes it.

AudioCategory and PreviewableCategory are declared in src/core/game/UserSettings.ts, not in src/client/soundsrc/core must not depend on the client, so the mixer imports the types from core rather than the other way round.

Tests

tests/client/UserSettingModal.audio.test.ts (15): six categories in mixer order; bare 0–100 with no %; each slider seeded from its own stored value; writes only its own key as value/100; no bus to emit on; test buttons on exactly the four previewable rows; previews the right category; disabled while its own cue is pending; disabled with the hint when the category is silent; no buttons at all before the mixer exists; a rejected preview re-enables the button and is swallowed by the component; both blur toggles stored; keep-alerts disabled while mute-on-blur is off; the same tab renders on the in-game instance; en.json copy exists for every key the tab renders.

tests/UserSettings.test.ts (+11): non-zero defaults; per-category key isolation; legacy sfx read-through to all four categories; legacy music read-through to music only; stored 0 respected; legacy 0 respected across alerts/ambience/interface too; new key beats legacy; legacy key left in place; out-of-range legacy clamped on read; clamping on write; the change event is keyed to the category; both blur toggles round-trip.

tests/client/sound/SoundManager.test.ts: volume tests converted from bus emits to settings writes, plus a new dispose() unsubscribes-from-settings test.

Every behaviour above was mutation-checked — fourteen mutations in total, each confirmed to fail the intended test and then reverted. One early assertion ("no unhandled rejection" via an unhandledrejection listener) survived its mutation and was replaced with one that does not.

resources/lang/en.json gains the audio_* keys and retires background_music_volume and sound_effects_volume, which nothing else referenced. Note the repo's TranslationSystem sync test does not catch a missing or unused user_setting key — I probed it both ways and it passed — so the tab's test file asserts the copy exists directly.

Merge Risk: 🔵 Low · up to 599ad

Users who enable mute-on-blur while already unfocused can hear audio until focus changes, and settings preview buttons can be missing until the modal next updates. These are bounded UI/audio behavior gaps that should be addressed before merge if this flow is important.

🤖 Claude Code Review

Verdict: ✅ No issues found — approve.

Findings: 0 critical, 0 high, 0 medium, 0 low.

No issues found. Checked for bugs and CLAUDE.md compliance.

Reviewed: CLAUDE.md i18n rules (all new strings route through translateText() with matching resources/lang/en.json entries, no other translation files touched), src/core determinism/testing rules (UserSettings.ts changes are prefs storage, not sim logic, and are covered by new tests in tests/UserSettings.test.ts), and the diff for logic errors, event-listener leaks, and security issues across UserSettings.ts, AudioMixer.ts, UserSettingModal.ts, SettingToggle.ts, SoundManager.ts, and MenuMusic.ts.

Three candidate issues were investigated and ruled out on validation:

  • A read/write asymmetry between the deprecated setBackgroundMusicVolume/backgroundMusicVolume shim methods in UserSettings.ts — real but unreachable, since this same PR deletes every remaining caller.
  • A possible listener leak in MenuMusic.ts's new settings-change subscription — the cleanup follows the file's existing pre-PR game-starting teardown pattern, not a new defect.
  • Four of the six new sliders (Master/Alerts/Ambience/Interface) currently have no effect via SoundManager, since the real per-category mixer is delivered by the stacked, unmerged branch (Replace sound effects and wire the full new audio delivery #5348) — the diff explicitly comments this as intentional/transitional.

🤖 Claude Code Review

Verdict: No issues found — 0 Critical, 0 High, 0 Medium, 0 Low.

Scope checked: CLAUDE.md compliance (i18n via translateText()/en.json, src/core determinism + test coverage, translation-file scope, testing patterns) and correctness/security bugs in the diff (src/core/game/UserSettings.ts, src/client/sound/*, src/client/UserSettingModal.ts, src/client/components/baseComponents/setting/SettingToggle.ts, src/client/hud/GameRenderer.ts, resources/lang/en.json, and associated tests).

Findings, and why each was ruled out:

  • Master/Alerts/Ambience/Interface sliders and the mute-on-blur toggles write to storage but currently have no audible effect, and the settings-tick sound effect is removed with no immediate replacement — both are explicitly called out in the PR description as intentional, disclosed limitations pending the stacked #5348 AudioMixer PR, not oversights.
  • A theorized race where dragging the Music slider mid-ambience-crossfade could cancel Howler's fade-out and leave two ambience loops running indefinitely does not hold up: Howler's _stopFade() still emits 'fade' before returning, so the .once("fade", () => current.stop()) cleanup still fires. The practical effect (an abrupt cut instead of a fade) is a pre-existing behavior from #5348's code, not something introduced here.
  • No CLAUDE.md violations: every new user-visible string is routed through translateText() with a matching en.json entry, no other translation files are touched, the only src/core change (UserSettings.ts) is deterministic local-storage logic with new tests added, and core logic is tested without mocks.

…b (OPE-420) (#5358)

The in-game menu offered two ways into graphics settings: the shared
settings modal's **Graphics** tab (#5353) and an older in-game-only
"Graphics Settings" modal that held every fine-grained option. This
folds the second into the first and deletes it.

Every option keeps its storage key and its read/write path.

## Why almost nothing needed new live-apply wiring

All of these options live under the single `settings.graphics` key, and
that key's change event *is* the live-apply mechanism:
`ClientGameRunner` listens for it, re-resolves the render settings onto
the renderer's live settings object, and rebuilds the GPU-derived state
(terrain texture, player colors, palette). So a running game follows the
moved controls with no renderer reference in the UI at all — exactly as
it followed the old modal.

**Map layers are the exception.** Their rows are enumerated from the
running map's layer manifest, and the renderer does not re-read layer
visibility or alpha from settings after startup. They still arrive as
`mapLayers` plus two renderer callbacks, now set by `GameRenderer` on
the in-game settings instance and forwarded to the advanced body.

## Option inventory

All keys are sub-paths of `settings.graphics` unless noted.

| Option | Storage key path | Live-apply |
| --- | --- | --- |
| Ambient light | `lighting.ambient` (slider 0–10 remapped) |
settings-changed event |
| Unit glow | `lighting.falloffPower` (inverse of slider) |
settings-changed event |
| Name scale | `name.nameScaleFactor` | settings-changed event |
| Minimum name size | `name.cullThreshold` | settings-changed event |
| Name opacity under cursor | `name.hoverFadeAlpha` | settings-changed
event |
| Hover glow size / strength | `name.hoverGlowWidth`,
`name.hoverGlowAlpha` | settings-changed event |
| Name color | `name.darkNames` | settings-changed event |
| Structure icon size | `structure.iconSize` | settings-changed event |
| Classic icons / level numbers / dots | `structure.classicIcons`,
`.classicNumbers`, `.showDots` | settings-changed event |
| Naval hover highlight | `mapOverlay.navalHighlight` | settings-changed
event |
| Territory / border highlight amount, thickness |
`mapOverlay.highlightFillBrighten`, `.highlightBrighten`,
`.highlightThicken` | settings-changed event |
| Territory saturation / opacity | `mapOverlay.territorySaturation`,
`.territoryAlpha` | settings-changed event |
| Coordinate grid opacity | `mapOverlay.coordinateGridOpacity` |
settings-changed event |
| Alt-view fill opacity | `altView.fillAlpha` | settings-changed event |
| Train track draw distance | `railroad.railMinZoom` (stored inverted) |
settings-changed event |
| Train track thickness | `railroad.railThickness` | settings-changed
event |
| Background / ocean / shore / plains / highland / mountain color |
`terrain.backgroundColor`, `.oceanColor`, `.sandColor`, `.plainsColor`,
`.highlandColor`, `.mountainColor` | settings-changed event (same
listener rebuilds the baked terrain texture) |
| Nuke fallout color | `mapOverlay.staleNukeColor` | settings-changed
event |
| Special effects | `passEnabled.fx` | settings-changed event |
| Fallout effects | `passEnabled.fallout` | settings-changed event |
| Highlight strength | `smallPlayerGlow.strength` (shown as %, stored
0–1) | settings-changed event |
| **Map layer show/hide** | `mapLayerVisibility[id]` | **renderer
callback** (`view.setLayerVisible`) |
| **Map layer opacity** | `mapLayerAlpha[id]` | **renderer callback**
(`view.setLayerAlpha`) |
| Save / copy / import preset | `settings.graphicsPresets`,
`settings.graphics` | event (import) |
| Reset to defaults | clears `settings.graphics` | event + re-pushes
every layer |

## Map layers: page instance vs in-game

**Hidden off a running game, not disabled.** The rows come from the
current map's layer manifest, so with no game there is no list to grey
out — a disabled section would be an empty box under a heading. This is
what the old modal did too (`mapLayers.length > 0`). Every other option
is pure preference and renders identically in both places: stored on the
page, applied at the next game start.

The advanced body also listens for the graphics key, so a preset applied
from the dropdown (or an import) redraws the controls *and* re-pushes
the layers to the renderer — the one thing a wholesale change would
otherwise apply everywhere except the map. Its own writes are marked
while they happen, so dragging a slider does not resync every layer.

## Preset tools placement

Save / copy / import sit at the **top level** of the Graphics tab,
beside the preset dropdown, rather than inside the Advanced fold. Saving
the look you just built is not itself a tuning control, and a player who
never expands Advanced should still find it. Advanced holds only the
tuning controls, plus Reset at the bottom.

The import parse is now guarded as well as checked: deeply nested input
survives `JSON.parse` and the schema (which strips what it does not
know) only to overflow the stack in the structural comparison behind
them. That is a `RangeError`, not a parse failure, but the player is
owed the same answer — it shows the existing invalid-JSON state instead
of escaping as an unhandled error.

## Deleted

- `src/client/hud/layers/GraphicsSettingsModal.ts`, and
`ShowGraphicsSettingsModalEvent` with it. Nothing else referenced either
(checked `Main.ts`, `GameRenderer.ts`, `index.html`, tests).
- `<graphics-settings-modal>` from `index.html`, plus its registration
and layer wiring in `GameRenderer.ts`.
- The second "Graphics Settings" row in the in-game menu.
- Six `en.json` keys that became unreferenced:
`user_setting.graphics_settings_label`,
`user_setting.graphics_settings_desc`, `graphics_setting.title`,
`graphics_setting.colored`, `graphics_setting.black`,
`graphics_setting.section_presets`,
`graphics_setting.section_custom_presets`. Every other
`graphics_setting.*` key is reused as-is, and no new key was needed.
`en.json` only — no other language file.

The legacy-presets migration moved from the deleted modal's `init()` to
`GameRenderer`, so it still runs at game start.

## Added

- `<graphics-advanced-settings>` — the tuning controls, self-contained
like `<graphics-preset-selector>`, behind an "Advanced" disclosure that
reuses the existing `graphics_setting.advanced_*` strings.
- `<graphics-preset-tools>` — save / copy / import.
- `<setting-color>` for the seven color pickers.
- `step` on `<setting-slider>`; the graphics sliders tune fractional
values.

Keeping the options in their own components holds
`UserSettingModal.ts`'s diff to the Graphics section.

## Tests

`tests/client/UserSettingModal.graphics.test.ts` (17):

- renders every folded control
- writes each option into the same `settings.graphics` shape the old
modal used
- flips each folded toggle away from its default
- ignores a partial hex, as the old picker did while typing
- resets every override from the Advanced fold
- offers save, copy and import without expanding Advanced
- saves the current configuration under a name
- applies an imported configuration
- flags an unparseable import instead of applying it
- flags a pathologically nested import instead of throwing
- fires the `settings.graphics` change event a running game listens for
- follows a preset applied from the dropdown, and re-pushes the layers
- applies a map-layer toggle to the renderer, and stores it
- applies a map-layer opacity to the renderer, and stores it
- re-pushes every layer to the renderer after a reset, as the old modal
did
- hides the map-layer section, because the rows come from the running
map
- shows the map-layer section once a game hands its layers over

`tests/client/InGameSettingsMenu.test.ts` (+2):

- offers one way into graphics, not a second advanced-graphics row
- reaches the advanced graphics options through the shared modal

Eight mutations were checked, each caught by the test named for it: rail
inversion dropped, layer-visibility callback dropped, layer section
never hidden, partial hex accepted, glow strength stored unscaled,
external-change listener removed, import `try`/`catch` removed, preset
tools pushed back inside the fold.

## Notes for review

- This PR and #5355 both touch `UserSettingModal.ts`, in different
sections — #5355 rewrites the Audio tab and `renderVolumeSlider`; this
one only touches the Graphics section, its new fields, and `updated()`.
- `tests/client/InventoryModal.test.ts` can time out when the whole
client suite runs in parallel. It passes in isolation and its slowest
test takes 3.7s against a 5s ceiling, so it is a margin problem in an
unrelated file, not something this branch introduced.

Verdict: No issues found — this PR is safe to merge as-is (pending normal review). Findings: 0 critical, 0 major, 0 minor.

Reviewed the diff against openfrontio/OpenFrontIO's root CLAUDE.md (i18n routing via translateText()/en.json, src/core determinism and dependency-freedom, src/core test coverage) and scanned for obvious bugs, logic errors, and security issues in the changed code (per-category volume sliders, clampVolume/read-through logic in UserSettings.ts, the previewCue/10s-ceiling race in UserSettingModal.ts, and the mute-on-blur toggle dependency).

  • All new user-visible strings (audio_master, audio_music, audio_effects, audio_alerts, audio_ambience, audio_interface + _desc variants, audio_mute_on_blur(+_desc), audio_alerts_when_unfocused(+_desc), audio_test, audio_test_muted) go through translateText() and have matching entries in resources/lang/en.json; no other translation files were touched.
  • src/core/game/UserSettings.ts's new clampVolume() helper is pure, deterministic arithmetic with no new dependencies, and is covered by new tests in tests/UserSettings.test.ts.
  • The previewCue/ceiling-timeout race, toggle-dependency logic (mute-on-blur ↔ alerts-when-unfocused), and removal of the legacy volume events/wiring were all verified against the diff and check out.

No inline comments were posted since no findings survived review.

Apply the current focus state in followFocus().

If AudioMixer starts hidden or unfocused, focused remains true until a later event. Non-exempt channels can then play despite muteOnBlur(). Invoke update() after registering the listeners so initialization uses the current document state.

🤖 Claude Code Review

Verdict: No issues found — 0 findings (0 critical, 0 major, 0 minor).

Reviewed the diff for CLAUDE.md compliance (i18n via translateText()/en.json, src/core test coverage, src/core dependency boundaries) and for bugs/logic/security issues in the new audio settings tab, mixer wiring, carve-out logic, and preview-cue race handling. One candidate issue (a new src/core/game/UserSettings.ts import of src/client/DesktopShell) was surfaced and investigated, but did not hold up: the same file already imports from src/client/StatsConstants prior to this PR, so this isn't a newly introduced boundary violation, and the CLAUDE.md "no external dependencies" language for src/core reads in context as referring to npm packages relevant to determinism, not same-repo cross-directory imports.

No issues found. Checked for bugs and CLAUDE.md compliance.

35-37: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

setAudioControls() only assigns a module variable. A page settings modal can render while it is null during bootstrap, and registration never requests a render, so its preview buttons remain absent until an unrelated state update. Notify consumers of audio-control registration and have the modal rerender when the provider changes.

🤖 Claude Code Review

Verdict: No issues found — this PR looks good to merge from a code-review standpoint.

Findings by severity: Critical: 0 · High: 0 · Medium: 0 · Low: 0

No issues found. Checked for bugs and CLAUDE.md compliance.

Reviewed areas:

  • CLAUDE.md compliance (two independent passes): all 20 new i18n strings go through translateText() with matching entries in resources/lang/en.json; no other language files touched; the one src/core/game/UserSettings.ts change includes test coverage and doesn't introduce non-deterministic simulation state.
  • Bug/logic scan (two independent passes): traced the volume clamp-on-read/write logic, the master-volume carve-out and its emit-once behavior, resetAudio()'s key coverage, the playTestCue Promise.race/ceiling-timeout cleanup, the audioControls() null-checks, and removal of the legacy eventBus/Set*VolumeEvent wiring for dangling references. No unconditional logic errors, compile issues, or security problems were found in the introduced code.

…uttons

Replaces the two volume sliders with the full mixer surface: Master,
Music, Sound Effects, Alerts & Notifications, Ambience and Interface,
each a bare 0-100 slider (unit="") because the value is squared into
perceptual gain before it reaches the audio — a percentage would be a
lie and dB would be worse.

Mute-on-blur and a dependent "keep alerts audible when unfocused" sit
below, both defaulting on, the second indented and disabled while the
first is off. `disabled` is new on setting-toggle and defaults to false,
so no other tab changes.

Effects, Alerts, Ambience and Interface each get a Test button —
Master is tested by every other button and Music is already playing.
A button calls audioMixer()?.previewCue(category), stays disabled until
its own cue resolves, and shows the audio_test_muted hint when the
category is silent or the mixer has not been constructed yet.

src/client/sound/AudioMixer.ts is the contract surface only: the
interface, and a null-until-registered accessor. The mixer itself lands
on #5348 and replaces that file wholesale, at which point the four
buttons light up. Until then the tab stores every value correctly and
the buttons are honestly disabled.

en.json gains the audio_* keys and retires background_music_volume and
sound_effects_volume, which nothing else referenced. The repo's
TranslationSystem sync test does not catch a missing or unused
user_setting key, so the tab's test file asserts the copy exists.

setAudioVolume clamps, but the legacy keys it reads through to were
never bounded, so a stored "settings.soundEffectsVolume" of 1.5 reached
the Audio tab as 1.5 and rendered 150 on a 0-100 slider. Verified
against the branch before fixing.

Adds the UserSettings audio tests the branch did not have: clamping on
read and on write, the legacy read-through to all four split channels,
a legacy 0 staying 0, and a channel's own key winning over the legacy
one. src/core change, so tests are mandatory.

…kbox in tests

A cue whose asset fails to load or play settles neither `end` nor `stop`
in Howler, so previewCue never resolves and the button stays disabled
for the life of the page. The preview now races a 10 s ceiling, cleared
on settle, so the worst case is one dead press rather than a dead button.

The toggle tests were selecting the setting-toggle host rather than its
checkbox — SettingToggle puts the same id on both, and querySelector
returns the host. They passed only because `checked` and `disabled`
happen to be reflected Lit properties on the host. They now select
`#id input[type="checkbox"]`, which is what a player actually clicks.

Josh's call, 11 Sept: the game keeps playing when the window loses
focus unless the player asks otherwise. alertsWhenUnfocused stays on —
it only applies once mute-on-blur is turned on, so its default is not
what a player experiences out of the box.

Updates every test that pinned the old default, including the branch's
own: the UserSettings focus-defaults case, and the mixer's focus-duck
cases, which now turn mute-on-blur on explicitly rather than leaning on
it being the default. The tab's keep-alerts test starts from the
dependent row being disabled, which is what a player now sees.

Also drops the UserSettings audio tests this PR had added that duplicate
the branch's own tests/UserSettings.audio.test.ts — a file I had missed.
Only clamping on read, which is this PR's change, remains there.

Evan's requirement: the web build must stay silent out of the box, as
main is today, while the Steam build starts audible. Only master is
platform-dependent — every channel default and the mixer itself are
identical everywhere.

Master has no legacy key of its own, so defaulting it to 0 on web would
silence a returning player who had deliberately set the old sliders.
The carve-out: web master defaults to 0 only when nothing audio-related
is stored at all — neither legacy key nor any settings.audio.* volume.
Store anything, and master defaults to 1.0 and that player keeps hearing
what they chose. A stored master always wins on both platforms.

isDesktopShell() is imported rather than inlined: DesktopShell.ts
imports nothing, so it cannot create a cycle. Verified with madge —
58 circular dependencies in this graph before and after, none involving
it.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
UserSettings.resetAudio() drops all eight settings.audio.* keys and the
two legacy ones, so the read-through and the master carve-out resolve
against a clean slate: web master 0, desktop master 1.0, channels at
their defaults, mute-on-blur off, keep-alerts on. Clearing the legacy
pair matters — leaving it would have the read-through hand the old
two-slider values straight back, which is not "defaults".

The change events carry the value each key now resolves to rather than
null. AudioMixer's listener parses `detail` as a number and drops NaN,
so a null payload would leave the mixer playing at the old volumes
while the tab showed the new ones. There is no cheaper "all changed"
signal in the contract, so it is one event per key as the setters do.

Plain secondary button at the foot of the tab, styled like the test
buttons, no confirmation: nothing is lost that a slider cannot put back.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…on reset

Two review findings, both player-visible.

The web master carve-out flips from 0 to 1.0 the moment any audio value
is stored, but only the written channel's key was emitted. A web player
with fresh storage who dragged Effects to 70 got a tab showing master
100 and a mixer still holding master 0: a silent game with the slider
claiming otherwise. setAudioVolume now snapshots the resolved master
before the write and emits settings.audio.master when it changes and no
master is stored. Both legacy setters route through it, so they are
covered; a later write emits nothing, since the value no longer moves.

SettingToggle bound `?checked`, an attribute. Once the player clicks the
box its dirty checkedness flag makes the attribute inert, so Reset to
defaults cleared storage but left the checkbox showing the old state.
Now a `.checked` property binding. Nothing depended on the attribute
form — the peer-checked styling keys off the :checked pseudo-class.

Also closes test gaps: audio_reset was missing from the modal test's
required-keys list, so deleting the en.json key failed nothing.

Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…lider fill in step

AudioMixer.isAudible() gates on master before the channel, so on a fresh
web install — master 0, every channel at its non-zero default — all
three Test buttons read "turn this category up". That blames a slider
which is already up, and the master row has no Test button, so the hint
could not be acted on. renderTestButton now checks master separately and
shows audio_test_master_muted when master is the blocker, falling back
to the channel hint otherwise. Disabled either way.

SettingSlider only set its --fill custom property on drag and on first
render, so a programmatic value change moved the thumb while the filled
part of the track stayed put. Reset to defaults made that visible on
every audio slider at once. Recomputed in updated() when value, min or
max change; dragging is unaffected, since handleInput already set it.

🤖 Claude Code Review

Verdict: No issues found — safe to merge. Findings: 0 Critical, 0 High, 0 Medium, 0 Low.

Reviewed the full diff (14 files: resources/lang/en.json, src/client/UserSettingModal.ts, src/client/components/baseComponents/setting/SettingSlider.ts & SettingToggle.ts, src/client/hud/GameRenderer.ts, src/client/sound/AudioMixer.ts, CuePlayer.ts, Sounds.ts, src/core/game/UserSettings.ts, and associated tests) with four independent passes: two for CLAUDE.md compliance, two for bugs/logic/security issues in the introduced code.

No violations of the repo's CLAUDE.md were confirmed:

  • All new user-facing strings route through translateText() with matching entries added to resources/lang/en.json; no other translation files touched.
  • The only src/core file changed (UserSettings.ts) has corresponding test coverage in tests/UserSettings.audio.test.ts and tests/UserSettings.test.ts.
  • UserSettings.ts gaining an import of isDesktopShell from src/client/DesktopShell was scrutinized closely against the "src/core has no external dependencies / must remain deterministic" rule. It extends a pattern this file already had before the PR (it already imported from src/client/StatsConstants and src/client/render/gl/GraphicsOverrides), the import is guarded (typeof window !== "undefined") so it degrades safely inside the Web Worker, and nothing in the deterministic tick/execution path reads it — so it doesn't rise to a clear, newly-introduced violation.

No significant bugs found. Reviewers specifically traced and confirmed as correct: the defaultMasterVolume/setAudioVolume "carve-out" before/after comparison and its single-fire change-event emission, resetAudio()'s cache-clear-then-re-emit sequencing against AudioMixer.followSetting's NaN guard, clampVolume bounds on both read and write paths, the previewing Set's per-category concurrency handling and the Promise.race preview-ceiling (no unhandled rejection, reliable clearTimeout), and the SettingToggle/SettingSlider binding changes (?checked.checked, the new updated() hook) for update-loop or stale-state risk.
