Terminal close actions always prompted, even for users who prefer closing terminals immediately.

Adds Terminal close confirmation under Settings → General → Confirmations. It stays enabled by default and can be disabled, searched for, or reset. The shared confirmation helper applies the preference to drawer and panel buttons, terminal tabs, and the terminal close keybinding on web and desktop.

Watch the demo video (23 seconds): default confirmation → disable the setting → close a terminal immediately.

Default confirmation	Setting disabled	Terminal closed without a prompt

Validation: 231 focused tests passed; web and contracts typechecks passed; scoped lint passed with warnings in existing SettingsPanels code. Verified in the real web client that disabled confirmation survives a reload and resetting the preference restores the dialog. Desktop uses the same helper; mobile currently has no equivalent user-triggered terminal close confirmation. No server, provider, or wire behavior changed.

Model: gpt-6.1-sol. Harness: Codex in T3 Code.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The preference preserves confirmation for individual terminal closes, but bulk panel-close actions now also prompt by default. A human should confirm this change to existing default behavior.

Walkthrough

Adds a client setting for terminal-close confirmation, enabled by default. Terminal-close requests use the hydrated setting to decide whether to show the confirmation dialog. General settings provides a switch and reset action, and settings search includes the preference.

Changes: Terminal Close Confirmation

Layer / File(s)	Summary
Settings contract packages/contracts/src/settings.ts, packages/contracts/src/settings.test.ts	ClientSettingsSchema defaults confirmTerminalClose to true. ClientSettingsPatch accepts the optional Boolean field. Tests cover the default and preservation of an explicit false.
Terminal-close confirmation gate apps/web/src/lib/terminalCloseConfirm.ts, apps/web/src/lib/terminalCloseConfirm.test.ts	The close flow hydrates settings before deciding whether to show the dialog. It skips the dialog when confirmation is disabled and continues to confirmation if hydration or settings access fails. Tests cover these outcomes and pending dialogs.
Preference controls and restore apps/web/src/components/settings/SettingsPanels.tsx, apps/web/src/components/settings/settingsSearch.ts, apps/web/src/components/settings/settingsSearch.test.ts	General settings adds a switch and reset action. Settings restore includes the preference, and settings search adds a terminal-close confirmation result.

Merge Risk: Low · previous review 1bad5

Bulk-closing right-panel tabs can stop terminal processes and delete their history without the confirmation users are told to expect when the preference is enabled. Align the bulk-close flow with the preference, or explicitly narrow the setting’s scope, before relying on it as protection.

Security architecture risk: Low · up to 1bad5

The change is limited to a client-side preference. Confirmation remains enabled by default, settings-read failures retain the prompt, and disabling it does not grant permission to operate terminals. No new security issue was established, although some persistence and recovery behavior remains unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The preference belongs to the client rather than a selected server environment. Disabling it can remove prompts for terminal actions across that client's connected environments, but the inspected execution paths retain their existing environment, thread, terminal identity, and permission checks. The destructive outcome remains process shutdown and terminal-history deletion.

Security Findings and Attack Paths

• observed — Auto-exit and bulk terminal closes bypass the individual confirmation helper, and the helper also permits closure when no local API is available. These exceptions predate this PR; the new preference does not introduce those paths. They are not retained as PR-introduced security concerns.

Trust Boundaries and Controls

• observed — Failed settings reads remain retryable and reject hydration. The close helper catches that rejection while keeping confirmation enabled; it does not interpret a storage-read failure as permission to skip the prompt.

Resilience and Maintainability Implications

• observed — The unchanged server close operation uses a per-thread locking wrapper. Session removal publishes a closed event only when a session was removed, and history deletion uses forced file removal. These existing mechanisms constrain repeated-close cleanup, but the inspection does not establish comprehensive crash recovery or interleaved reopen behavior.

surfaces through “Close others,” “Close to right,” or “Close all” honors the
terminal-close confirmation setting before invoking the close callback. Reuse
confirmTerminalClose and the existing terminal labels and authorization checks;
retain the browser-close confirmation behavior and proceed with closing only

Takeover update (head 87ca33d1a2)

• merged current main with a merge commit (no conflicts).
• fixed the red Test Web / Check: ThreadTerminalDrawer.browser.test.tsx mocks useSettings, and the mock lacked ensureClientSettingsHydrated and getClientSettings, which terminalCloseConfirm.ts now imports. the suite failed to import. added both to the mock; no product code changed.
• vp run check:changed passed through blacksmith-check: format, lint, knip, typecheck (36 packages), 7 test files including the drawer and useRightPanelSurfaceClose browser tests.
• earlier review findings (settings hydration, search destination, bulk-close confirmation) are already fixed on this head.

the verification below was recorded by an earlier pass on head 33000b3c1a, before the contributor's rebase; it was not repeated for this update.

Verified in a real dev environment

verified unchanged head 33000b3c1a5affca9a3f9afb72cae0e8c3bc4137 on this linux boat vm, using repo playwright and /usr/bin/google-chrome against real dev servers. installed dependencies with vp i on both checkouts. ran main first in ../main at 15fe283272, stopped it, then ran this exact pr head. created the project, threads, and real codex gpt-6.1-sol turns through the web app on both; both returned "terminal verification ready." no mocks, fixtures, or replay provider.

• main always prompted on terminal close and offered no terminal confirmation preference.
• this head prompts by default. cancel preserves the terminal and its running child process. disabling the preference closes immediately and stops that process.
• settings search opens the control at settings → threads. the opt-out survives reload; ctrl+w respects it. the row's reset restores the prompt.
• panel close works. bulk close prompts with both terminal labels; cancel retains both tabs. close to the right removes only its target. with confirmation disabled, close others preserves the selected tab and close all removes the remainder without prompting.
• 52 focused tests across four existing files passed through blacksmith-check: terminal confirmation, shortcut guards, settings schema, and settings search. github reports 22 successful, 10 skipped, and 1 neutral check, with no pending or failed checks.

observed through the real client/server websocket connection:

client: terminal.close {terminalId:"term-1", deleteHistory:true}
server: terminal event {terminalId:"term-1", type:"closed"}
server: terminal list event {terminalId:"term-1", type:"remove"}
server: request exit Success

short command transcript

before on main, with the same prompt and provider response:

Not verified

native electron dialogs on macos/windows, native ios/android, remote/relay/tunnel connections, restricted terminal permissions, storage-read failure recovery, and bulk closing mixed agent-controlled browser/terminal tabs were not exercised on this linux web setup. other providers were not exercised. no code changes or pushes were needed.
