Why

On a desktop every pane opens in its terminal; only an agent pane on a touch screen opens its chat. Someone who reads their agents as conversations has to switch each pane by hand, and every new pane starts in the terminal again.

Change

Settings → Chat → Panes open in: Auto / Chat / Terminal, for every pane on this device.

• Auto is today's rule and the default.
• Chat opens an agent pane's chat. A shell pane, which has no conversation, still opens its terminal.
• Terminal always opens the terminal.
• Choosing forgets each pane's remembered lens (herdr-web-ui:view:*), so the choice reaches every pane at once.
• A pane switched by hand afterwards keeps its lens until the choice changes again.
• A PC without terminal attach still opens chat, as before.

Strings are added for ko, ja and zh.

Validation

• Unit (settings.test.ts): only known choices are kept, with auto as the default. forgetPaneViews removes every pane's lens and nothing else.
• Browser (scripts/default-view-regression.ts, from test:ui), on a desktop page with two agent panes:
  • a pane opens its terminal by default;
  • after choosing Chat, the open pane and a pane that remembered the terminal both open their chat;
  • a pane switched back by hand keeps the terminal.
• Typecheck passes.

📝 Summary

Summary by CodeRabbit

• New Features
  • Added a “Panes open in” setting to choose whether panes default to Auto, Chat, or Terminal.
  • When Chat is selected, panes open in Chat if an agent is available; otherwise, they open in Terminal. Auto retains automatic view selection.
  • Changing the setting clears saved pane-view preferences. Manually selected views persist when switching panes.

Walkthrough

Adds an Auto, Chat, or Terminal pane-view setting. Changing it clears saved per-pane views. Pane selection uses the configured default, and browser regression coverage checks the behavior.

Changes

Default pane view

Layer / File(s)	Summary
Default view preference and saved-view cleanup src/lib/settings.ts, src/lib/settings.test.ts	Adds the defaultView preference with auto, chat, and terminal values. Invalid values fall back to auto. forgetPaneViews removes stored pane-view keys while preserving other settings, and tests cover these cases.
Setting control and pane view selection src/components/SettingsDialog.tsx, src/App.tsx, src/lib/i18n.*.ts	Adds Auto, Chat, and Terminal choices. Changing the setting clears saved pane views. Pane selection uses the configured default, while retaining the existing touch-screen heuristic for Auto. Adds Japanese, Korean, and Simplified Chinese translations.
Browser regression coverage scripts/default-view-regression.ts, scripts/ui-regression.ts	Adds and runs a browser check for initial view selection, applying Chat to both panes, clearing a saved view, preserving a manual Terminal selection across pane switches, and resource cleanup.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Feature

Merge Risk: 🔵 Low · up to ddd0e

The setting appears to work, but the browser check does not protect the remembered-pane case it claims to cover. Correct that fixture as a bounded follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 241be

The change selects between existing pane views and preserves the existing terminal capability check. Storage failures can leave inconsistent pane choices, but no new access or privilege was identified in the reviewed paths. Broader authorization behavior was outside this review.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The preference reset reaches remembered lenses for all matching panes in the browser origin’s storage, including different machine identities. Its observed mutation scope is presentation state; the cleanup prefix excludes the settings record and does not select credentials or server-owned workspace state.

Security Findings and Attack Paths

• inferred — The inspected default-view path adds no credential, role, route, or authority-bearing input to terminal attachment or chat submission. It chooses between existing manually selectable lenses rather than establishing a new privileged attack path. The canonical Security section contains no retained findings, but its unknown coverage does not establish safety outside these paths.

Trust Boundaries and Controls

• observed — The preference is constrained to a closed set of values, remembered lenses are accepted only as chat or terminal, and terminalAttach is checked before either preference is consumed. No new server-side identity or authorization decision is introduced by the selector.

27-27: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Seed the key that storedView reads.

forgetPaneViews removes every key beginning with herdr-web-ui:view:, including the incorrect herdr-web-ui:view:local:${pane} key. The current assertion therefore passes when that incorrect key is removed. It does not verify that the genuine local-pane key is cleared.

Seed and assert herdr-web-ui:view:${pane} instead.

Suggested fix

-      localStorage.setItem(`herdr-web-ui:view:local:${pane}`, "terminal"); // a pane that remembered the terminal
+      localStorage.setItem(`herdr-web-ui:view:${pane}`, "terminal"); // a pane that remembered the terminal
...
-    assert.equal(await page.evaluate((pane) => localStorage.getItem(`herdr-web-ui:view:local:${pane}`), two), null, "what a pane remembered gives way to the choice");
+    assert.equal(await page.evaluate((pane) => localStorage.getItem(`herdr-web-ui:view:${pane}`), two), null, "what a pane remembered gives way to the choice");

Update the localStorage key used by the regression test around
`forgetPaneViews`: seed and assert `herdr-web-ui:view:${pane}` instead of
`herdr-web-ui:view:local:${pane}` so the test verifies the key that `storedView`
reads is cleared.

[devswha]

Reviewed default-view selection, existing per-pane overrides, shell fallback, no-terminal-attach behavior, storage failure handling, and settings reset. Resolved the main conflict by keeping both reconnect and default-view browser checks, and added the changelog entry. Typecheck and 39 focused tests pass; both required CI jobs pass on this exact head.
