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: a save that changes an appearance value waits for the host's answer. (A save that changes a time or date value already waited on main, through displayChanged, and still does; this PR does not extend it to any other setting.) 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.
MCP switch inside a save with appearance values (mcpEnabledChanges.ts, McpHub.handleMcpEnabledChange): the objective is the same all-or-nothing save. The switch is applied in that save, and the wait for it is bounded like every other store of the save, so a disconnect that never finishes cannot keep the appearance records for good. A change cannot be cancelled, so a bounded wait needs three things, each as small as it can be: changes of the switch go one at a time per hub with at most one waiting behind the one under way (a newer value replaces the waiting one, and a retried save joins the change under way, so a stalled change cannot make a queue grow or start a second disconnect on a closing transport); once the changes in line have settled, one reconciliation per hub brings the hub back to the stored setting; and a hub that was disposed applies no change. A save without appearance values awaits the change exactly as before.
Plain settings (config/storeInOrder.ts, config/giveUp.ts): in a save with appearance values the wait for each store is bounded, and a store cannot be cancelled, so a store that timed out may land after the write of a later save, an import or the public API. Stores of one key therefore go one at a time, in the order the writes were made (a save, writeValuesThroughWriteChain for imports and the API). A write that has not started is taken back when its save times out or its provider is disposed (an AbortSignal per save, aborted by ClineProvider.dispose), and so is an MCP change that waits behind another (dropped when no other save waits for it); a write that has started cannot be taken back. The reconciliation after a stalled MCP change holds providers only weakly and asks none that was closed.
SettingsView.tsx: a refresh after an import takes an appearance value only when the import says it stored it, so an edit of a value that another provider changed is kept; every setter that has its own handler records its edit, so a late refresh keeps it.
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.
Improved handling of settings saves and imports, including partial failures and delayed results. The unsaved-changes dialog now notes when a save may still complete after you leave.
Settings-save errors provide clearer feedback when some values may have changed.
This PR adds four persisted appearance settings, exposes them in the settings UI with preview and localized text, applies them to webview rendering, and updates host save, import, rollback, state sequencing, and MCP-related coordination for those settings.
Adds interfaceFontScale, terminalFontSize, editorFontSize, and spacingScale. The webview gets steppers, preview, CSS-variable application, localized strings, gallery stories, and tests. Chat rows, queued messages, terminal output, code blocks, markdown, Mermaid errors, and diff code now read the new appearance variables.
Sequenced state and acknowledged saves packages/types/src/vscode-extension-host.ts, src/core/webview/ClineProvider.ts, webview-ui/src/context/ExtensionStateContext.tsx, webview-ui/src/components/settings/SettingsView.tsx, webview-ui/src/components/settings/UnsavedChangesDialog.tsx, webview-ui/src/hooks/useLatestRef.ts, src/core/webview/__tests__/ClineProvider.spec.ts, webview-ui/src/components/settings/__tests__/SettingsView*.tsx, webview-ui/src/context/__tests__/*, webview-ui/src/hooks/useLatestRef.spec.tsx
State payloads now include the four appearance values, appearanceSeq, and optional import-refresh metadata. ClineProvider avoids posting state after disposal. The frontend merges appearance snapshots by sequence, applies document-root variables, tracks request-based appearance saves, handles late answers and timeouts, defers navigation during pending saves, and shows the optional save-outcome note in the discard dialog.
Appearance saves now validate changed values before writes, serialize writes per setting, use time-bounded waits, roll back failed writes when possible, and report stored, not-stored, and uncertain keys. Imports and API configuration use the same write path, send refresh metadata after partial or deferred outcomes, and add localized save-failure messages for partial-change cases.
MCP enablement changes are serialized per hub with one pending follow-up value. Pending callers can give up before start. Reconciliation reads stored values from the latest live owner after queued changes settle. McpHub.handleMcpEnabledChange now exits immediately when the hub is disposed.

Merge Risk: Low · up to 19b22
The appearance settings feature works as described, and failed saves are now validated and rolled back for the four new settings. A few rare edge cases remain, mostly around MCP servers after a stalled save and a full reset landing during a rollback. These can leave a setting or servers out of sync until the user saves again. They do not affect normal use, but the MCP case is worth fixing before merge.

[#2222] The PR adds the four requested UI steppers, resets, and live preview. The appearance utilities and CSS consumers apply the settings; the terminal consumer uses the configured size, and the editor-size class limits diff changes to configured values.

Explanation
The save-result, rollback, write-ordering, import-refresh, and disposal changes support reliable persistence and display of the four appearance settings across overlapping saves and other write paths. The UI and visual changes cover appearance behavior and its consumers. The current summary limits host validation to the four new appearance values; the prior finding about validating chatFontSize no longer applies. No demonstrated unrelated change remains.

Explanation
A queued import can re-enable auto-approval after the user disables it. appearanceSettingWrites.ts:583-606 queues autoApprovalEnabled writes, but the checkbox handler writes directly at webviewMessageHandler.ts:2424-2426. If an earlier store delays an import of true, the user can disable auto-approval before the queued import starts. The import then stores true, allowing configured actions to proceed without a prompt. The previous failure is addressed: imports now use the queue, and timed-out saves abort queued writes.
Resolution
Coordinate the direct auto-approval toggle with queued writes. Prevent older queued enables from overriding a later disable. Add a regression test for a delayed import followed by disabling auto-approval.
Full details: Persistence Integrity
Explanation
SettingsView.tsx:349-376 can still discard an unrelated unsaved edit. A partial-import refresh preserves the edit but clears its tracking. If another partial-import refresh then includes a changed live value for that setting, the form replaces the edit even though the import did not store it. A later save persists the replacement. The other prior findings are addressed: plain settings now use storeInOrder for saves, imports, and API writes; the queue stores each waiting write separately.
Resolution
Keep unrelated unsaved edits tracked across partial-import refreshes. Track edits made after an import answer separately for late-refresh handling. Add a regression test with two partial refreshes and an intervening live-state change.
Full details: Lifecycle Resource Cleanup
Explanation
A disposed provider can remain retained by a queued MCP save. In mcpEnabledChanges.ts:119-140, aborting one waiter removes its value but returns the shared pending promise without rejecting that waiter if another waiter remains. A save without appearance values awaits that promise without a timeout (webviewMessageHandler.ts:934-938). If the running MCP change stalls, the disposed provider and its suspended handler remain retained indefinitely. ClineProvider.dispose() aborts the waiter but does not release its handler in this case.
Resolution
Give each pending MCP waiter its own promise. Reject and detach an aborted waiter without cancelling the shared change needed by other waiters. Add a test with a stalled change, two queued providers, and disposal of one provider.

## 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.

Updates for the three failed checks and the coverage report:
Out of Scope Changes: the wait for the save result for a time or date change is not new. It is on main already (displayChanged in SettingsView.tsx), and this PR only adds the appearance values next to it. The description said otherwise and is corrected. The MCP switch handling has an explicit objective in the description now (the bounded wait of the all-or-nothing save), and it is smaller: one change running and at most one waiting per hub (newer values replace the waiting one), one reconciliation per hub, and a disposed hub applies nothing.
Persistence Integrity: every dedicated setter (setOpenRouterImageApiKey, the image provider and model, debug, telemetry, experiments, support prompts, API configuration) records its edit by state key, so a late import refresh keeps it. Regression tests: the OpenRouter image key edited between the import answer and the late refresh is kept, and an unedited one takes the stored value (mutation-checked).
Lifecycle Resource Cleanup: the queue holds at most two changes per hub whatever the number of alternating saves, and reconciliations are one per hub and read what is stored when the changes are done. Tests: 51 alternating saves behind a stalled change, a waiting value that equals what was just applied, a failed change before a waiting one, one reconciliation for 20 saves, and a reconciliation that reads the stored value at the end.
Codecov: the only partial line was an if/else in the test helper vscodeEditorFontSize.ts; it is now a single call.

Cancel pending MCP changes when their saves time out or their owners are
disposed. Keep reconciliation for already-started changes without retaining
disposed providers. Cover stalled changes, timed-out pending changes, retries,
and disposal with a shared active hub.

Review comments at @src/core/webview/mcpEnabledChanges.ts:
- Around line 105-121: Update reconcileMcpEnabled to re-check getStored() after
each change settles, continuing until no change is running and the stored value
matches changes.last; stop reconciliation after a failed apply rather than
retrying it. Add a regression test that stalls the initial true change, queues
changeMcpEnabled(hub, false), calls reconciliation again while storage remains
true, then releases both changes and asserts the last hub call is [true].
Review comments at @src/core/webview/webviewMessageHandler.ts:
- Around line 980-1000: Update the rollback loop in the updateSettings flow to
start undoSettingWrite calls concurrently in reverse order and await all of
them, rather than awaiting each rollback sequentially. Preserve each rollback’s
error logging and onDeferredSettled behavior.
Review comments at
@webview-ui/src/components/common/__tests__/CodeBlockLineHeight.visual.tsx:
- Line 5: The test.describe block in CodeBlockLineHeight.visual.tsx only checks
computed line-height and lacks a visual assertion. Keep those checks and add a
focused toHaveScreenshot assertion for the markdown-list-code story with
--zoo-editor-font-size set to 32px, using the suite’s established deterministic
screenshot setup.
---
Failed pre-merge checks:
- Regression Evidence:
Add a focused test that queues a timed-out change during a stalled
reconciliation and verifies that the hub returns to the stored setting. Update
reconciliation to handle that case.
- Persistence Integrity:
Serialize or reconcile timed-out non-appearance writes so they cannot overwrite
newer writes. Preserve unrelated unsaved edits during partial-import refreshes
by identifying the settings the import changed. Add regression tests for both
cases.
- Lifecycle Resource Cleanup:
Cancel pending MCP changes when their saves time out or their owners are
disposed. Reconcile started changes without retaining disposed providers. Cover
stalled changes, retries, timeouts, and disposal with a shared active hub.

- Around line 2550-2553: Update the test around save and the stalled writes to

flight: the timeFormat write and both restores. Keep the subsequent timer
advance and rejection assertion unchanged.

handleMcpEnabledChange to clear changes.last when it still matches the failed
attempted value, before finish(false) starts any pending change. Add a test that
fails reconciliation and then reconciles the same stored value, verifying the

### When a UI change needs a snapshot
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.

Learning: Persistence integrity: Fail only when a concrete changed persistence path can lose or corrupt state because an operation is not awaited, a write is non-atomic, rollback or explicit partial-failure behavior is missing, or a persisted default is not propagated to a consumer. Cite the changed path and a plausible triggering scenario; pass when no such changed path exists.
980-1003: Starting the restores together with Promise.all removes the 45 s serial worst case. The worst case is now about 30 s. That is still above the 20 s webview save-answer timeout reported in the earlier review. The webview can mark the outcome unknown before settingsSaveResult arrives. A previous review comment already raised this timeout-budget mismatch.

## Unit & State Tests (Vitest + JSDOM)
- Prefer local `webview-ui` tests for React/webview behavior. If a change is about component rendering, local state, hooks, form dirty-state, validation, or prop wiring inside the webview, add or update Vitest coverage under `webview-ui/src/**/__tests__` instead of reaching for `apps/vscode-e2e`.

## Unit & State Tests (Vitest + JSDOM)
- Use `@/utils/test-utils` `renderWithExtensionState` and `makeExtensionState` for common context/query setup. Keep component-specific mocks and state transitions local when they explain the scenario.
Changes for the failed merge checks and the coverage report:
Persistence Integrity: (1) stores of one key now go one at a time (storeInOrder.ts, at most one waiting, a newer value replaces it), so a timed-out openRouterImageApiKey store cannot land after, and overwrite, the store of a retried save. Test: the older store lands late and the newer one is stored after it (final value is the newer); unit tests for the line. (2) a refresh after an import takes an appearance value only when the import stored it, so an unsaved edit of a value that another provider changed is kept and still sent with the next save (test, mutation-checked); every dedicated setter records its edit (one test per setter, each mutation-checked).
Lifecycle Resource Cleanup: a save that gives up on an MCP change that has not started removes it from the line (dropped when no other save waits; the value of the remaining save is used otherwise); the reconciliation keeps providers only through a WeakRef and asks none that was closed, so it does not retain a closed provider while a shared hub is stalled. Tests: dropped, kept for another save, too late to take back, already aborted, listener removed, closed and open providers; handler test with a stalled enable and a queued disable that times out (the disable never starts).
Codecov (SettingsView, webviewMessageHandler, CodeBlock): tests for the setters above, the legacy refresh without stored keys, updatePrompt with an open and a disposed provider, and a host without ResizeObserver.

Failed pre-merge checks:

Limit the new extension-host validation to the four appearance settings
requested by #2222. Keep existing `chatFontSize` validation behavior unchanged,
or link a requirement that justifies changing it.
- Security Boundaries:
Coordinate all writers of approval settings in the same per-key ordering, and
remove queued writes that time out before starting. Add a regression test for a
timed-out queued enable followed by a newer disabling import.
- Persistence Integrity:
Order non-appearance writes across all persistence paths, including API and
import writes. Preserve unrelated unsaved non-appearance edits during
partial-import refreshes. Report superseded writes as not stored rather than
successful. Add regression tests for each scenario.
- Lifecycle Resource Cleanup:
Cancel queued MCP waiters on provider disposal without cancelling work needed by
other saves. Detach timed-out or disposed queued setting writes and release
their provider references. Add tests for stalled writes, disposal, and shared
hubs.

## Visual Tests (Playwright Story Gallery)
### When a UI change needs a snapshot
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.
… API; take back queued stores and MCP changes on timeout and disposal; chat font size not validated here; keep unsaved edits through an import refresh
Out of Scope Changes: chatFontSize is no longer validated by this PR (only the four new values are); a test pins that it is stored as before.
Security Boundaries / Persistence Integrity: stores of one key now go one at a time in the order the writes were made, for the saves and for writeValuesThroughWriteChain (imports, the public API, a new task's configuration), so a timed-out enable of an approval setting cannot land after, and overwrite, the import that turned it off. A write that has not started when its save times out is taken out of the line (AbortSignal), so it is never stored later. There is no replacing of a waiting write any more: every caller gets its own outcome, and the middle of three overlapping saves is stored too (it is not reported stored without being stored). Tests: the timed-out enable followed by the disabling import (final value false, the enable never started; mutations on the signal fail it), unit tests of the line (order, failure, abort, an aborted write behind a stalled one, 50 timed-out callers leave nothing), and of the import and API path through writeValuesThroughWriteChain.
Persistence Integrity (import refresh): a refresh after an import no longer replaces a value that the user has edited here when the import did not store it (appearance or not); one test per dedicated setter, mutation-checked.
Lifecycle Resource Cleanup: ClineProvider.dispose takes back the stores and MCP changes that its saves queued and that have not started (giveUpAllOf); a started one goes on. Tests: a stalled store and a stalled MCP change with a waiting store and a waiting MCP change behind them, disposed: the waiting ones never start (a mutation on the abort fails it); the provider test pins the call.

- Around line 963-979: Update the save flow around storeInOrder so MCP
reconciliation runs after the relevant ordered store settles, including stores
that reject after timing out. Ensure reconciliation observes the latest result
after later stores have had their turn and respects current hub state; do not
reconcile immediately on timeout or store failure while an earlier store may
still change the cache.

queued enables from overriding a later disable. Add a regression test for a
delayed import followed by disabling auto-approval.
- Persistence Integrity:
Keep unrelated unsaved edits tracked across partial-import refreshes. Track

An earlier disable store can time out while its cache value is false. A retry can then disconnect the servers and time out waiting behind that store. If the earlier store later rejects and reads back true, MCP remains enabled in state but its servers remain disconnected. Neither store failure triggers reconciliation.
Reconcile after the relevant ordered store settles, accounting for later stores and hub changes. An immediate reconciliation can read the cache before the earlier store settles.

Review comment at @src/core/webview/webviewMessageHandler.ts around lines 963 -
979:
Update the save flow around storeInOrder so MCP reconciliation runs after the
relevant ordered store settles, including stores that reject after timing out.
Ensure reconciliation observes the latest result after later stores have had
their turn and respects current hub state; do not reconcile immediately on
timeout or store failure while an earlier store may still change the cache.

Description
This PR adds font size and spacing settings to the UI tab.

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: a save that changes an appearance value waits for the host's answer. (A save that changes a time or date value already waited onmain, throughdisplayChanged, and still does; this PR does not extend it to any other setting.) 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.mcpEnabledChanges.ts,McpHub.handleMcpEnabledChange): the objective is the same all-or-nothing save. The switch is applied in that save, and the wait for it is bounded like every other store of the save, so a disconnect that never finishes cannot keep the appearance records for good. A change cannot be cancelled, so a bounded wait needs three things, each as small as it can be: changes of the switch go one at a time per hub with at most one waiting behind the one under way (a newer value replaces the waiting one, and a retried save joins the change under way, so a stalled change cannot make a queue grow or start a second disconnect on a closing transport); once the changes in line have settled, one reconciliation per hub brings the hub back to the stored setting; and a hub that was disposed applies no change. A save without appearance values awaits the change exactly as before.config/storeInOrder.ts,config/giveUp.ts): in a save with appearance values the wait for each store is bounded, and a store cannot be cancelled, so a store that timed out may land after the write of a later save, an import or the public API. Stores of one key therefore go one at a time, in the order the writes were made (a save,writeValuesThroughWriteChainfor imports and the API). A write that has not started is taken back when its save times out or its provider is disposed (anAbortSignalper save, aborted byClineProvider.dispose), and so is an MCP change that waits behind another (dropped when no other save waits for it); a write that has started cannot be taken back. The reconciliation after a stalled MCP change holds providers only weakly and asks none that was closed.SettingsView.tsx: a refresh after an import takes an appearance value only when the import says it stored it, so an edit of a value that another provider changed is kept; every setter that has its own handler records its edit, so a late refresh keeps it.packages/types: thesettingsSaveResultmessage type.common.json(18 locales):errors.settings_save_failed, shown when a save is rolled back.Test Procedure
