feat(ui): add interface, terminal, editor font size and spacing settings - #2224
This PR adds font size and spacing settings to the UI tab.
Settings
Interface font size (50-200%), Terminal font size (8-32 px), Editor font size (8-32 px), and Spacing density (50-200%). Each has a stepper and a reset.
A live preview that follows the steppers before the user presses Save.
How it works
Each value maps to one CSS variable on <html>. A value that is not set removes the override, so the stylesheet default applies.
With nothing set, the layout and the sizes of code, diff, and terminal blocks do not change. The editor size reaches the diff view only while a value is set (a class on <html>).
The preview sets each unset value to initial. A value saved on <html> cannot leak into the preview, so a reset shows before Save. The preview uses the same fallbacks as the live UI.
Review notes
The four settings go through the updateSettings message. Reset values are sent as null so that they clear the stored value.
The review gate flagged that the four values were part of a save that was not atomic. The save pipeline changes below fix that. See "Save pipeline changes".
Most of the diff is the 17 locale files. Only the ui.appearance strings are added.
Save pipeline changes
The "Persistence Integrity" check reported that the four appearance values are saved in a loop that can stop half way. A failed write left some values stored and the rest not, and the webview could not tell. The changes below fix that, and nothing else about how settings are applied. The API configuration, telemetry, and debug messages are sent immediately, exactly as before, and every side effect of a setting runs in the same place as before.
webviewMessageHandler.ts, updateSettings: the four appearance values (interfaceFontScale, terminalFontSize, editorFontSize, spacingScale) are saved all-or-nothing. Each is recorded, with the value it had, right before it is written. If a write fails, the ones this save already stored are put back in reverse order, and so is the one whose own write failed, in case it changed the stored value before failing. The store is shared by the sidebar and the editor tab, so saves can overlap. The writes to one key form a chain. A write is put back only while it is the latest one and the stored value is still what it wrote, so a newer save's value, and a change made outside a save (an import), are kept. A write that fails while a newer one is pending is taken out of the chain, so if the newer one fails too, it restores what was stored before either of them, in whichever order they fail. Writes of one appearance value run one at a time, from every save and every rollback and across providers, and each stays in line until it has reached durable storage, so a slower write cannot complete after a newer one and overwrite it. A write that fails does not hold up the ones behind it. Writes that have finished are taken out of the chain, so nothing is kept about them once the saves are over. The result is posted as settingsSaveResult (success or the error), also when the state refresh fails, and the refresh runs after the values were put back.
The four appearance values are validated in the extension host, with the schemas they are defined with (an integer within its bounds, or null for a reset), before any side effect runs or any setting is stored. An invalid value changes nothing, not even the valid settings sent with it. The save fails with an error and the webview is told. The webview is not trusted: the stepper's limits do not bind a message that was written by hand. Other settings are not checked, as before.
A failure while writing any other setting follows the existing error path, as before, with one addition: the webview is told the save failed (it is waiting for the result), and then the error is rethrown. No error is shown for it, as before. Every other setting is written exactly as before, and the loop itself is unchanged.
The error shown for a failed appearance save does not claim a full restore: it says some settings may be left partly changed.
Not part of the transaction, on purpose: every other setting, and the side effects that run in place while saving (the language, speech, the terminal settings, the command lists in VS Code configuration, the MCP servers, the destructive command guard install). They behave as before and are not undone by a failed save.
SettingsView.tsx: only a save that changes an appearance value waits for the host's answer. For that save, Save is disabled while it is pending, and the "unsaved changes" flag clears only when the host reports success, so a failed save keeps the edits and can be retried. An edit made while it is pending keeps the flag. Request ids (saveRequestId.ts) combine a per-load id with a counter, so an answer from an earlier mount or before a reload cannot match a later save. Every other save behaves exactly as before: no request id, nothing to wait for, and the flag is cleared at once. The existing SettingsView tests for those saves are unchanged.
packages/types: the settingsSaveResult message type. common.json (18 locales): errors.settings_save_failed, shown when a save is rolled back.
Test Procedure
pnpm check-types passes in webview-ui, src, and packages/types.
Webview tests pass. New tests cover the appearance save and reset, the ExtensionStateContext hydrate and update path, and the save result flow (success, failure, edit during a save, late answers).
Extension tests cover the all-or-nothing save (restore order, a newer value is kept, a failing restore, no request id, a failed state refresh).
A Playwright snapshot covers the preview in four themes, with set values and with a reset while <html> holds saved values.
Manual: open Settings > UI. Change each value. Check the preview. Press Save. Check the chat. Reset each value.
Added appearance controls for interface scaling, chat spacing, terminal text, and editor/code text, with adjustable values and reset options.
Added a live preview to see appearance changes before applying them. Settings also affect chat, terminal, code, and diff views.
Bug Fixes
Appearance-setting saves now validate values and report failures. Navigation waits while a save is pending; if no response arrives, a notice explains that the save may still complete after leaving.
Documentation
Added translated appearance controls, preview text, and save-status messages.
The change adds four optional appearance settings for interface scale, spacing, terminal font size, and editor font size. The webview adds controls, previews, and CSS application. Host write paths validate and serialize appearance updates, and the settings view handles save acknowledgements and timeouts.
The schema and extension state include the four settings. The webview applies their values to CSS variables used by chat, code, diff, and terminal content. The preview uses local appearance values. Tests cover state updates and rendered styles.
Appearance controls and save acknowledgements webview-ui/src/components/settings/NumberStepper.tsx, webview-ui/src/components/settings/UISettings.tsx, webview-ui/src/components/settings/SettingsView.tsx, webview-ui/src/components/settings/__tests__/*SettingsView*, webview-ui/src/components/settings/__tests__/NumberStepper.spec.tsx, webview-ui/src/components/settings/__tests__/UISettings.spec.tsx, webview-ui/src/i18n/locales/*/settings.json
The UI adds numeric controls, resets, and an appearance preview. Appearance saves track edited values and wait for host results. The view handles failed, timed-out, and late results and holds navigation while a save is pending. Locales add appearance and save-outcome text.
The host validates appearance values and serializes per-key writes. Failed writes can be rolled back, and queued writes can be dropped on timeout or provider disposal. Settings saves, imports, and configuration updates use the shared write path and test coverage. Error messages describe possible partial changes.

Explanation
The title "feat(ui): add interface, terminal, editor font size and spacing settings" matches the main change in the changeset. The diff adds four appearance settings (interface font scale, terminal font size, editor font size, spacing scale) with steppers, a live preview, CSS variables, and host-side persistence. The title omits the save-pipeline changes, which the description covers, but it does not need to list every detail.
Full details: Description check
Explanation
The description follows the repository template's main sections: Related GitHub Issue (Closes #2222), Description, Test Procedure, Pre-Submission Checklist, and a Visual Snapshots reference. It explains the how (one CSS variable per value, unset values removing overrides, the preview using initial, and the all-or-nothing save pipeline) and lists the tests run. Several template items are weak or missing. The Visual Snapshots section has no committed snapshot link or before/after images, although the checklist says a snapshot was added. The Videos, Documentation Updates, and Get in Touch sections are absent or not filled in. The checklist marks Visual Snapshot as complete while the test procedure describes the snapshot only as a Playwright test. The description also says the review gate flagged a non-atomic save, which is internal process detail rather than a reviewer-facing note. The Test Procedure claims that Playwright results pass, but the objectives say the browser result remained unverified.
Full details: Linked Issues check
Explanation
Open directly linked issue [#2222] requires four UI-tab controls with reset actions, live preview, safe ranges, accessible steppers, default preservation, and translations. The changed code adds the four bounded nullable settings, renders NumberStepper controls with keyboard and assistive-technology support, applies and removes CSS variables, isolates preview values, preserves unset code/diff/terminal defaults, and adds translations in all listed locales. Tests cover bounds, reset, persistence, preview, state hydration, consumers, and save behavior.
Full details: Out of Scope Changes check
Explanation
The save acknowledgement, validation, rollback, write ordering, and state sequencing changes support reliable persistence of the four appearance settings in [#2222]. Changes in importExport.ts, api.ts, and provider write routing keep appearance writes safe across existing save paths. The added pending-save translations and tests support this behavior. The summary identifies no unrelated product behavior.
Full details: Regression Evidence
Explanation
No explicit regression-evidence failure is present. The changed appearance logic has focused coverage at the relevant layers: schema and range tests in packages/types/src/__tests__/global-settings.test.ts; clamping, CSS-variable clearing, and editor-class tests in webview-ui/src/utils/__tests__/appearance.spec.ts; stepper, reset, accessibility, typing, bounds, and unset tests in NumberStepper.spec.tsx; state hydration and stale-sequence tests in ExtensionStateContext.spec.tsx; and save acknowledgement, failure, timeout, rollback, late-result, and retry tests in SettingsView.saveResult.spec.tsx and webviewMessageHandler.spec.ts. The durable UI changes are covered by Playwright component tests and committed snapshots: AppearanceConsumers.visual.tsx checks set and unset behavior for chat rows, queued messages, Markdown, code, diff, and terminal output, while AppearancePreview.visual.tsx covers saved-value isolation and reset previews. UISettings.visual.tsx also has updated snapshots for the visible controls. No affected error, negative, or unset branch is evidently omitted.
Full details: Security Boundaries
Explanation
No changed path meets the failure condition. webviewMessageHandler.ts validates appearance values before side effects or storage. appearanceSettingWrites.ts repeats validation for API and import writes. appearance.ts clamps values before writing CSS variables and emits only numeric pixel or scale values. The new state fields contain appearance settings only; no changed code exposes secrets or bypasses approval or allowlist controls.
Full details: Persistence Integrity
Explanation
The prior disposal rollback defect remains. In updateSettings, a started appearance write is rolled back with owner: provider (src/core/webview/webviewMessageHandler.ts:939-967). ClineProvider.dispose() marks that owner disposed (src/core/webview/ClineProvider.ts:964-967). If the started ContextProxy.setValue updates cached/storage state and rejects before the 15-second timeout, staleKeys is cleared before undoSettingWrite runs. The rollback then calls queuedSettingWrite without behindStale, which refuses the disposed owner (src/core/config/appearanceSettingWrites.ts:116-129, 296-324). The failed value can therefore remain persisted. Existing disposal tests cover timeout/deferred rollback, not this dispose-then-reject-before-timeout path.
Resolution
Allow rollback writes to run after provider disposal by using a provider-independent owner, such as the shared ContextProxy, when the original owner is disposed. Continue detaching provider callbacks. Add a regression test where a started appearance write changes storage, the provider is disposed, the write rejects before the timeout, and the rollback restores the previous value.
Full details: Lifecycle Resource Cleanup
Explanation
The prior lifecycle failure remains. updateSettings now awaits a potentially timed-out appearance write, but its continuation has no disposal guard. After ClineProvider.dispose() sets _disposed and calls disposeSettingWrites(this), webviewMessageHandler.ts still runs the rollback continuation, calls provider.postStateToWebview() at lines 991-996, and attempts settingsSaveResult at lines 998-1005. postStateToWebview() constructs state and increments its sequence before postMessageToWebview() checks _disposed (ClineProvider.ts:2961-2965, 1726-1735). A started store that times out and then settles after provider disposal can therefore trigger state construction and result work after disposal. The changed handler tests cover timeout and callback detachment, but no test covers disposal during this handler continuation.
Resolution
Add a provider disposal or generation guard to the updateSettings continuation. After disposal or provider replacement, skip rollback refresh callbacks, postStateToWebview(), and settingsSaveResult; guard postStateToWebview() before state construction. Keep started storage and durable rollback active, with provider-owned callbacks detached. Add a regression test that starts a write, disposes the provider after timeout, releases the store, and asserts no state-post or save-result work occurs and that write bookkeeping is cleaned.

## Unit & State Tests (Vitest + JSDOM)
- When a regression can be proven with a component or webview integration test, keep it in `webview-ui`. Do not promote it to e2e just because the UI is hosted inside VS Code.
[warning] 36-36: This synchronous effect update causes an extra render: Calling setState synchronously within an effect can trigger cascading renders. Prefer deriving or initializing the value before render. If the effect must read a browser API after mount, treat this as advisory or suppress it with // react-doctor-disable-next-line react-hooks-js/set-state-in-effect.
Effects are intended to synchronize state between React and external systems such as manually updating the DOM, state management libraries, or other platform APIs. In general, the body of an effect should do one or both of the following:
Update external systems with the latest state from React.
Subscribe for updates from some external system, calling setState in a callback function when external state changes.

Persistence integrity:updateSettings is now all-or-nothing. Each key is snapshotted before it is written. If any write fails, the earlier ones are restored, the user is shown an error, and the webview gets a settingsSaveResult. SettingsView keeps the edits and the unsaved flag until the host confirms, and only then sends the API configuration, telemetry and debug settings. There is a new errors.settings_save_failed string in all 18 locales.
Tests:SettingsView saves all four appearance values and persists null for each after Reset. ExtensionStateContext hydrates and updates the values, treats null as unset, and applies or removes the CSS variables. There are also all-or-nothing tests in webviewMessageHandler.spec and a SettingsView.saveResult spec.
Changed-line count: extension 69, webview 355, types 16 (all under the 500 cap).
@coderabbitai the queue finding is addressed in the latest push. The queue no longer releases a key when the 15-second timeout fires:
A write that had started keeps its key until its store has settled. Meanwhile a new write of that key is refused at once ("An earlier write of has not finished yet"), not queued, so a late store can never land after, and overwrite, a newer write, and a store that never settles holds one entry and one closure rather than one per attempt.
A write whose caller gave up before it started is dropped, so it never lands later.
The other keys are not affected.
Tests: with a deferred store, the caller is told after 15 seconds, the new write is refused and nothing newer is stored, the late store lands, the key is free again and a following write goes ahead; a queued write that timed out before it started is never issued; another key keeps working. Not marking the key as taken, or running a dropped write after the first lands, fails these. The webview already treats a save that gets no answer as an unknown outcome and says so to the user.
@KarthickMahalingam The current code at 507a4b7b1 addresses the reported late-write overwrite race.
In src/core/config/appearanceSettingWrites.ts:
Lines 95–99 reject the caller on timeout without releasing the key.
Lines 76–78 reject new same-key writes while the timed-out store remains outstanding.
Lines 101–114 drop writes that timed out before starting and release started writes only after storage settles.
The tests in src/core/config/__tests__/appearanceSettingWrites.spec.ts, Lines 200–269, cover late settlement, same-key refusal, recovery, dropped writes, and independent keys.
Keeping an outstanding storage operation is not itself the previous cleanup defect. The key distinction is that retries no longer accumulate behind that operation.
This was source inspection, not a test run or a fresh pre-merge check. Run the focused suite in CI and refresh the saved gate results before merging. The saved timeout-release findings describe the previous implementation.

performSettingWrite by invoking finishSettingWrites with that write after the

leave the asserted behavior unchanged.
Review comments at @src/core/config/appearanceSettingWrites.ts:
- Line 232: Update the APPEARANCE_SETTING_KEYS filter in the appearance write
flow to select a setting only when settings owns that property, so inherited
values are not persisted or returned as appearance state.
- Around line 202-205: Update undoSettingWrite’s restore logic to track whether
the failed write still owns the setting instead of relying only on getValue
matching write.wrote; ensure resetAllState invalidates that ownership when it
clears the key, so rollback does not restore write.previous after a reset.
- Around line 192-195: Update the rollback chain in the queued-write handling
around unlinkSettingWrite so a timed-out queued interfaceFontScale write
restores the value that preceded the first write after that late store settles.
Preserve the outstanding store value through the chain instead of checking
against the queued write’s value before the earlier write has completed.

…r; appearance writes are owned by their provider and dropped on disposal; a handed-over rollback also covers the value a late store lands; own properties only; Playwright case for the configured chat font size
@coderabbitai the checks on this PR are addressed in the latest push:
Persistence Integrity (the webview can be left with a value that is not persisted): the rollback of a timed-out write is attached to its store. When that store has settled and the conditional rollback has run, a callback refreshes the webview (updateSettings, ClineProvider.setValues, and API.setConfiguration each pass postStateToWebview), so it shows what is really stored, including when the store failed late and nothing had to be put back. Tests with a real deferred store in the message handler, the chain and the provider.
Lifecycle Resource Cleanup: appearance writes now have an owner, the provider's ContextProxy. ClineProvider.dispose calls disposeSettingWrites, which drops every write and every deferred rollback of that provider that has not started (never issued, callers told, timers cleared) and leaves other providers' writes alone. A store that has already started cannot be cancelled (globalState.update has no cancellation) and runs on; its key stays taken until it settles.
Regression Evidence (MarkdownBlock): a Playwright case in the appearance-consumers fixture sets a configured --zoo-chat-font-size (16px) and the 150% interface scale and asserts the rendered chat text is 24px, then clears each in turn and asserts 1.5 times the default and then the default. It needs the CI browser run to confirm: it cannot run in my environment.

@KarthickMahalingam I inspected head 01bcd05b2. Two changes match the requested fixes, but the disposal path still has a gap.
Persistence Integrity: The deferred rollback now invokes the refresh callback after completion, including after a late store failure. updateSettings, ClineProvider.setValues, and API.setConfiguration pass refresh callbacks. The handler regression test checks for a second state refresh after late settlement.
Regression Evidence:AppearanceConsumers.visual.tsx, Line 92–124, now checks 16px × 150% = 24px, followed by both fallback states. This covers the previously missing configured-chat-font branch. The browser result remains unverified.
Lifecycle Resource Cleanup: Cancellation prevents a queued write from executing, but does not detach its continuation. In appearanceSettingWrites.ts, Line 125–130, cancel only sets gaveUp, clears the timer, and rejects the caller. The prior.then(...) continuation at Line 140–158 still retains write until the preceding store settles. If that store never settles, a cancelled rollback still retains its ContextProxy. Also, rejecting that rollback invokes onDeferredSettled through .finally(...) at Line 256, so disposal can trigger a refresh of the disposed provider.
Please detach provider-owned callbacks when cancelling queued work. Preserve the shared key barrier until the started store settles. Add a disposal test that leaves the store unresolved and verifies that no refresh occurs after disposal.
CI also has a confirmed blocker:mutation-diff reports 567 changed executable webview lines, above the 500 limit. Split the change or obtain the maintainer-reviewed narrow exclusion specified by the check. The inspected check results still showed the browser and platform unit tests as pending.
This was source inspection, not a test run or a refreshed CodeRabbit pre-merge assessment. I used the supplied persisted-setting and regression-coverage guidance.

- Around line 239-242: Update the appearance write handling around restore so a
failed clear cannot restore a value superseded by resetAllState. Route reset
writes for appearance keys through the write chain or invalidate pending writes
when reset runs; preserve rollback behavior for writes that have not been
superseded.
- Around line 92-94: Update disposeSettingWrites so disposing an owner does not
silently discard the rollback for a timed-out save. Preserve that rollback while
detaching provider-owned callbacks, or establish and implement the alternative
behavior of treating a late store as persisted and informing the user that the
save result is stale; add a test confirming the chosen outcome.
- Around line 92-95: Update the disposal tracking used by disposeSettingWrites
and the updateSettings loop so disposal state belongs to the provider that
issued the update, not the shared ContextProxy; check that state before each
appearance write so writes reached after disposal are dropped without blocking
writes from a surviving provider. Add a test covering a write registered after
disposal.
- Around line 125-131: Update the give-up paths in cancel and the write timeout
handling to replace the queued write with a non-capturing no-op, so the pending
continuation no longer retains the provider’s ContextProxy while still reaching
release(). Apply the same release principle to the rollback restore closure when
a refused save adds a rollback continuation.

…d proxy); a write that never started stores and rolls back nothing; a disposed provider's rollback callbacks are detached; a write that gives up releases its closure
@coderabbitai the persistence and lifecycle findings of the last check are fixed in 1790de4:
Persistence Integrity: a write whose store was never issued (refused while a store was outstanding, dropped at its timeout or at disposal) is marked as skipped, and its rollback puts nothing back unless it took over the value of an earlier write that may have stored it. Provider B's write of the same value as provider A's, dropped when B is disposed, can no longer undo A's successful write: a test runs exactly that sequence and the stored value stays A's. A skipped write also leaves no rollback continuation behind, which bounds what a run of refused saves holds.
Lifecycle Resource Cleanup: the write function is released when a write gives up or settles; disposal is tracked per provider (not per shared ContextProxy), refuses later writes of that provider, drops its writes that have not started, and detaches the callbacks of rollbacks waiting behind a store. The store that has started cannot be cancelled and keeps its key until it settles, and a waiting rollback still runs, so the stored value is put right. appearanceSettingWrites.ts is fully covered, and the handler's refresh-failure log is tested for an Error and for a plain value (the Codecov partial line).
@KarthickMahalingam I inspected head 1790de44b. The skipped-write change addresses the reported persistence failure. One lifecycle case remains.
Persistence Integrity:performSettingWrite marks unissued writes as skipped. undoSettingWrite excludes their attempted values from rollback candidates. The cross-provider regression test covers the same-value disposal case.
Lifecycle Resource Cleanup: In src/core/config/appearanceSettingWrites.ts, Line 303–306, undoSettingWrite registers onDeferredSettled without checking whether the owner is already disposed.
The remaining sequence is:
A provider starts a store that remains unresolved.
The provider is disposed before the 15-second timeout.
The timeout rejects the write. The save handler then registers its deferred rollback callback.
If the store never settles, that callback retains the disposed provider. If the store settles, the callback calls the disposed provider.
disposeSettingWrites clears callbacks that exist at disposal. It cannot clear callbacks registered afterward. The new test covers registration before disposal, but not this order.
Please suppress callback registration for an already-disposed owner. Keep the storage rollback and per-key barrier intact. Add a regression test that disposes the provider before timeout, then checks that late settlement restores storage without calling the refresh callback.
This was source inspection, not a test or coverage run. The inspected CI results still showed mutation-diff, browser tests, and platform unit tests as pending. The earlier 567-line failure does not establish the current result.
I applied the supplied persistence-integrity and lifecycle-cleanup guidance.

@coderabbitai the remaining lifecycle case is fixed in the latest push: undoSettingWrite registers no refresh callback for an owner that is already disposed, so a provider disposed before the write timed out (the store having started, so it cannot be cancelled) is neither called back nor kept alive by the callback, whenever the store settles. The storage rollback and the per-key barrier are unchanged. The regression test disposes the provider 5 seconds in, lets the write time out, registers the rollback afterwards, lands the store late and checks that the value is put back, the callback is never called and the queue is empty. Registering the callback regardless fails it. appearanceSettingWrites.ts is fully covered.

- Line 394: The undoSettingWrite call passes the callback where
SettingWriteOptions is expected, so the callback is never exercised. Pass
settled as the onDeferredSettled property in the third argument’s options
object, preserving the assertion that non-deferred rollbacks do not invoke it.

- Around line 26-33: Remove the test that defines and compares its own
counterOnly function, since it does not exercise production code. Keep the
existing reload-case test using nextSaveRequestId, and move the rationale into
that test as a comment only if it remains useful.

If your PR changes anything a user would notice at a glance — layout, spacing, theme tokens, brand elements, gradients, mask/blur effects, hover/empty/error states — **add a `*.visual.tsx` snapshot to the same PR**. Do not attach screenshots to the PR description as evidence; commit the baseline instead so future PRs get regression coverage automatically.

## ESLint Suppressions
### Typed test files
New or substantially changed test files must not add `typescript-eslint/no-explicit-any` suppression entries to `src/eslint-suppressions.json`:
- Prefer typed structural doubles: type mock context/proxy classes against the real public types they stand in for (e.g. `vscode.ExtensionContext`), and use `unknown` for storage values and mock callback parameters instead of `any`.
- Access private members with bracket notation (`provider["view"]`) and call public members without casts so their generic signatures keep checking arguments.
- When a partial double cannot be assigned to the real type, cast it once at the construction site (`as unknown as T`) with a comment naming the members the double provides; do not repeat `as any` at every use site.
- Validate with `pnpm --dir src run check-types`, the narrowest affected Vitest suite, and `pnpm --dir src exec eslint --prune-suppressions --max-warnings=0 <relative-test-...

[warning] 40-40: This synchronous effect update causes an extra render: Calling setState synchronously within an effect can trigger cascading renders. Prefer deriving or initializing the value before render. If the effect must read a browser API after mount, treat this as advisory or suppress it with // react-doctor-disable-next-line react-hooks-js/set-state-in-effect.
Effects are intended to synchronize state between React and external systems such as manually updating the DOM, state management libraries, or other platform APIs. In general, the body of an effect should do one or both of the following:
Update external systems with the latest state from React.
Subscribe for updates from some external system, calling setState in a callback function when external state changes.
[warning] 467-467: JSON.parse(JSON.stringify(x)) deep-clones by re-serializing: it is slow on large objects and silently drops undefined, functions, Date/Map/Set, and cyclic references. Use structuredClone(x).
Replace JSON.parse(JSON.stringify(value)) with structuredClone(value). It is faster and preserves Dates, Maps, Sets, and cyclic references.
[warning] 311-311: This side-effecting call runs inside a state updater, which React may invoke more than once. Move it outside the setter after computing the next state.
React may replay a state updater, so callbacks, analytics, and persistence inside it can run more than once. Compute state purely, then perform the side effect outside the setter.
Resolves the conflicts with the time and date settings (Zoo-Code-Org#2223). The appearance write chain and the save acknowledgement are kept, and extended: the three display settings are validated like on main, written like any other setting, and a save that changes one of them waits for the host like one that changes an appearance value.

that write bookkeeping is cleaned after late settlement.

144-157: Functional Correctness
The new pre-write check applies strict validation to chatFontSize. It rejects a whole save when the key is in the payload and the value fails the schema. The schema and the code agree on that behavior.
Whether this blocks unrelated saves in practice depends on two facts not yet established. First, the webview must send chatFontSize on every save. Second, some write path must be able to store an out-of-range value. The repository does not sanitize chatFontSize on read, but the import and API write paths were not inspected, so the second premise cannot be decided from the supplied evidence. The proposed remedy depends on the same unresolved premise. Do not post a change request until those paths are checked.

updateSettingsmessage. Reset values are sent asnullso that they clear the stored value.ui.appearancestrings are added.Save pipeline changes
The "Persistence Integrity" check reported that the four appearance values are saved in a loop that can stop half way. A failed write left some values stored and the rest not, and the webview could not tell. The changes below fix that, and nothing else about how settings are applied. The API configuration, telemetry, and debug messages are sent immediately, exactly as before, and every side effect of a setting runs in the same place as before.
webviewMessageHandler.ts,updateSettings: the four appearance values (interfaceFontScale,terminalFontSize,editorFontSize,spacingScale) are saved all-or-nothing. Each is recorded, with the value it had, right before it is written. If a write fails, the ones this save already stored are put back in reverse order, and so is the one whose own write failed, in case it changed the stored value before failing. The store is shared by the sidebar and the editor tab, so saves can overlap. The writes to one key form a chain. A write is put back only while it is the latest one and the stored value is still what it wrote, so a newer save's value, and a change made outside a save (an import), are kept. A write that fails while a newer one is pending is taken out of the chain, so if the newer one fails too, it restores what was stored before either of them, in whichever order they fail. Writes of one appearance value run one at a time, from every save and every rollback and across providers, and each stays in line until it has reached durable storage, so a slower write cannot complete after a newer one and overwrite it. A write that fails does not hold up the ones behind it. Writes that have finished are taken out of the chain, so nothing is kept about them once the saves are over. The result is posted assettingsSaveResult(success or the error), also when the state refresh fails, and the refresh runs after the values were put back.nullfor a reset), before any side effect runs or any setting is stored. An invalid value changes nothing, not even the valid settings sent with it. The save fails with an error and the webview is told. The webview is not trusted: the stepper's limits do not bind a message that was written by hand. Other settings are not checked, as before.SettingsView.tsx: only a save that changes an appearance value waits for the host's answer. For that save, Save is disabled while it is pending, and the "unsaved changes" flag clears only when the host reports success, so a failed save keeps the edits and can be retried. An edit made while it is pending keeps the flag. Request ids (saveRequestId.ts) combine a per-load id with a counter, so an answer from an earlier mount or before a reload cannot match a later save. Every other save behaves exactly as before: no request id, nothing to wait for, and the flag is cleared at once. The existingSettingsViewtests for those saves are unchanged.packages/types: thesettingsSaveResultmessage type.common.json(18 locales):errors.settings_save_failed, shown when a save is rolled back.Test Procedure
