Returning to a thread with an open terminal moved focus away from the composer, even when the composer had focus when leaving. Thread entry now remembers composer or terminal-pane focus and restores it on return. Explicit terminal actions keep priority, and first-entry defaults stay the same.

Fixes https://git.cafe/pingdotgg/t3code/issues/29041. This is a focused restoration bug fix under the small obvious bug exception. It adds no setting and does not revive the autofocus preference rejected in https://git.cafe/pingdotgg/t3code/pulls/8372.

Verification:

• The real-DOM composer-return regression fails with the original focus helper and passes with the fix. The two focused suites pass 25 tests; coverage includes drawer/panel restoration, explicit terminal requests, drawer closing, and environment-scoped thread identity.
• vp run check:changed upstream/main passed: formatting, lint, knip, affected typechecks, 81 tests in seven files, and selected React Compiler checks.
• In the real Linux web client, with two stopped Replay showcase threads and a 1440×900 CSS viewport: focus the composer in A, switch A→B→A. Before, the active DOM element belongs to the drawer; after, it is the composer. Also verified drawer and split-pane restoration, right-panel terminal restoration with the drawer open and closed, focused drawer closing to the composer, next/previous-thread keys, and command-palette return.

Before recording, 15 seconds · After recording, 12 seconds

Captures show the base production focus modules versus the original focus fix at 36825f6932. The later remount correction was checked separately: an added row in the existing DOM test fails before it and passes after it. In the real client, a synthetic parked request injected through the production focus helper no longer prevents composer restoration after leaving for Pull Requests and returning to a freshly mounted chat. Diagnostic outlines and the label reflect document.activeElement; shell prompts are masked for privacy. Those annotations are capture-only. Evidence is hosted as GitHub assets on the contributor fork, with no proof assets committed.

Web and desktop share this frontend. Native Electron, mobile, other operating systems, relay/tunnel transports, and sidebar terminal reveal were not exercised in the live pass; explicit reveal precedence and environment isolation are covered by the focused tests. No provider, contract, or settings changes.

Reviewed with review-loop: 2 rounds with Claude Opus 5.5 on xhigh. Reviewer verdict: approved for the core implementation. The later CodeRabbit remount finding was reproduced and corrected with the focused regression and real-client check described above.

Modernization against current main preserves the sidebar-rename focus guard introduced by #27287. The existing useFocusComposerOnThreadOpen hook now owns the restoration lifecycle and delegates target selection to terminalFocus.ts; the separate ChatView terminal-entry effect is removed. Explicit terminal requests, drawer-close fallback, and remount handling remain unchanged.

Modernization verification: the composer-return regression fails against current main's production focus helper, with focus on the drawer, and passes with this change. All 26 tests across terminalFocus.test.ts, terminalFocus.browser.test.ts, and useFocusComposerOnThreadOpen.browser.test.tsx pass, including the sidebar rename guard. vp run check:changed upstream/main passed on the rebased head over 4e0b52806be8: formatting, lint, both knip passes, affected typechecks (web and scripts), 91 tests in 10 files, and four selected React Compiler checks. Typechecking emitted non-failing suggestions already present in main.

The existing real-client captures above are historical evidence. A new integrated real-client pass was not run during modernization; native Electron/mobile and relay/tunnel verification remain outside this pass.

Walkthrough

The change records composer or terminal focus for each thread and restores a usable target when the thread is entered again. The chat view and terminal drawer provide the context used by the focus logic. Browser tests cover restoration and related focus behavior.

Changes: Thread focus restoration

Layer / File(s)	Summary
Capture and restore thread focus apps/web/src/lib/terminalFocus.ts	The focus module records composer or terminal focus by scoped thread reference. On thread entry, it restores a remembered composer or an available terminal, then falls back to the active drawer terminal or composer.
Wire thread entry to focus restoration apps/web/src/components/chat/useFocusComposerOnThreadOpen.ts, apps/web/src/components/ChatView.tsx, apps/web/src/components/ThreadTerminalDrawer.tsx	The hook passes the thread reference, workspace root, and terminal visibility to the focus module. The chat view removes its separate thread-entry effect. The terminal drawer registers its mount element.
Validate thread focus restoration apps/web/src/lib/terminalFocus.browser.test.ts, apps/web/src/components/chat/useFocusComposerOnThreadOpen.browser.test.tsx	Browser tests cover focus restoration, explicit navigation focus, environment isolation, hidden drawers, drawer closure, and the hook’s root-element setup.

Merge Risk: Low · previous review 79415

The change restores composer or terminal focus when returning to a thread. Two narrow edge cases can still leave focus on the page body or let the composer take focus from a terminal. Both are recoverable by clicking, and the main behavior works as intended. These are worth addressing but do not block the merge.

Full details: Title check

Explanation

The title "fix(web): restore composer focus when returning to a thread" matches the main change. The summary shows thread entry now remembers composer or terminal focus and restores it on return, and the linked objectives describe the same bug. It is a conventional commit title in plain language and stays concise.

Full details: Linked Issues check

Explanation

[#29041, #33028] The current head keeps the focus-restoration design from the previous review. terminalFocus.ts stores each thread's last composer or terminal focus in lastThreadFocus, scoped per content root. On return, focusTerminalOnThreadEnter restores the remembered target when it is still usable. Otherwise it falls back to the active drawer terminal or the composer, which keeps the first-entry default. ChatView.tsx no longer calls the unconditional drawer-terminal focus on every entry. Handler-requested focus, including sidebar terminal reveal (focusTerminalOnNavigation), is still honored first, as #33028 requires. useFocusComposerOnThreadOpen.ts now passes the scoped thread reference, root, and terminal-open state to this helper. The browser test file adds coverage for composer and drawer return, explicit terminal navigation precedence, environment isolation, pending drawer focus, and composer fallback. The remount correction is covered by an added regression row, as the PR description states. Test results and the live check are taken from the PR description and the change summary. I did not re-run them.

Full details: Out of Scope Changes check

Explanation

[#29041, #33028] The changed files map to the focus objectives. terminalFocus.ts and useFocusComposerOnThreadOpen.ts hold the restoration logic. ChatView.tsx removes the old enter-focus effect and passes new arguments. ThreadTerminalDrawer.tsx supplies the terminal mount element as the focus target. terminalFocus.browser.test.ts and useFocusComposerOnThreadOpen.browser.test.tsx cover the new behavior. The change summary shows no settings, provider, or contract changes, and no unrelated modules are listed. Based on the summary, the changes stay within scope. I did not read the full diff for this assessment.

Full details: Description check

Explanation

The description follows the repository template closely. It has a clear Problem (returning to a thread with an open terminal moves focus away from the composer), a Change section that explains the restoration logic and the removal of the ChatView terminal-entry effect, a Scope section that links issues #29041 and #33028 and cites the small obvious bug exception, and a detailed Verification section with focused test counts, a full check run, a manual real-client pass, and before/after screenshots and recordings hosted as GitHub assets. It also names the agent and model used. Gaps: the Verification section mixes historical evidence from an earlier head with the rebased head, and the author says a new integrated real-client pass was not run after modernization. Native Electron, mobile, and relay/tunnel behavior was not verified. The description is long and includes review-process detail that the template does not request, but it is substantively complete.

Verified in a real dev environment

Verified unchanged head 46de105638527dd6ecf53e57df0af1c977f2e698 in Linux Chrome at 1440×900, using repository Playwright against a background dev server.

On github/main (8648aea3db), added a real git project through the UI and created two threads with completed Codex gpt-6.1-sol turns. With the terminal drawer open, focused the composer in A, switched A → B → A, then typed focus-check. Main sent that text to the terminal (document.activeElement was the terminal textarea).

Stopped main and started the exact PR head with an explicit isolated home, preserving the app-created project and threads. The same interaction restored the composer and appended focus-check to its draft. A real follow-up Codex turn completed with PR_FOCUS_READY.

Neighboring checks passed: terminal focus survives A → B → A; a shell command runs in that terminal; closing the drawer focuses the composer; a thread with its drawer closed focuses the composer; explicitly reopening the drawer focuses the terminal.

Before, typing after return enters the terminal:

After, typing after return appends to the composer:

Both recordings show the same app-created threads. The after recording also shows the completed follow-up provider turn. Playback and seeking were checked after upload.

Runtime transcript. On Blacksmith, both existing terminal-focus suites passed: 25 tests in 2 files. GitHub CI checks were passing. No source changes or push were needed.

Not verified

Native Electron, iOS/Android, macOS/Windows, relay/tunnel and multi-environment connections were not exercised on this Linux VM. Right-panel/split-terminal restoration, command-palette and next/previous-thread navigation, and the stale-request remount scenario were not exercised manually in this pass; the existing focused suites cover panel restoration, environment isolation, explicit navigation precedence and remount handling. Other provider runtimes were not exercised.

Preserve terminal focus if it changes before the composer frame runs.

If entry schedules composer restoration and an explicit action focuses a terminal before the next frame, this callback still calls focusComposer(). The sidebar-input guard does not protect the terminal action. Skip the deferred callback when terminal focus has taken precedence. The PR objective requires explicit terminal actions to retain priority. (raw.githubusercontent.com)

Focus the composer when a remembered terminal cannot take focus.

If a drawer remains open in state but its viewport is absent or cannot operate, focusTerminal() parks the request without focusing a target. This restoration branch does not try the composer. Returning from another thread can therefore leave focus on body; a later terminal mount can also take focus after the user has clicked the composer. Fall back to the composer for an unavailable remembered target without changing explicit terminal requests. (raw.githubusercontent.com)

Evidence

Open A’s terminal drawer, click its composer, and type “Draft: ”. Select B, return to A through the sidebar, and type “composer restored”. Repeat after deliberately focusing A’s terminal, typing “terminal draft” before leaving and “ restored” after returning.

Every capture uses the real web app in Chromium on Linux, light theme, 1280×800 viewport, with separate fresh databases and identical synthetic replay threads. Terminal prompts were simplified before recording. All four stills passed identical-image checks 500 ms apart.
