A pending question replaced the composer draft, leaving no way to continue the message already being written. This adds Back to message / Answer question while keeping the question visible. Each mode restores its own text and caret; option selection while writing the message preserves that draft.

Credit to @tiliakoos for the original implementation in #17673. Maintainer takeover preserves the contributor commits and merges main. Scope stays on the trapped-message defect; broader answer/draft work in #13865 is separate.

The rebuild uses two bounded local caret snapshots and the existing draft/answer stores. Message mode survives option advancement and queued-edit target changes, and clears for a different thread/request. Provider trait updates do not replace the active answer reference or clamp its caret to the hidden message. Choosing a predefined option intentionally replaces the custom answer for that question; it does not append it to the message. Existing attachment, permission, submission and compaction gates remain in use.

Verification:

• PR-added tests: 5 cases across 2 files → 1 integrated hook/panel/editor/store regression in the existing navigation browser file. The expanded case starts with a nonempty answer and proves the message text, prompt reference and caret survive option selection and question advancement. Removing the relevant guards fails it.
• 271 focused unit tests and 5 headless browser tests passed; changed-file lint/format and web typecheck passed.
• Linux full web client, isolated projection fixture: actual main has a saved Please fix auth message but only exposes the question answer; rebuilt head returns to that message. Mid-text carets survive repeated switching in both directions. Typing inserts at the restored positions. Selecting an option advances to question two without appending the old custom answer or changing the message caret. The 390px layout also returns to the message. A literal initial answer containing @ and Markdown punctuation restores its mid-text caret across the editor remount and accepts typing at that position.
• Three adversarial review rounds; both final reviewers reported no findings.
• An inert client queue fixture exercised production queued-edit entry/cancel paths and kept message mode. This does not verify queue persistence or save RPCs.

Before — main exposes only the answer while the message is saved:

After — return to the saved message while keeping the question visible:

Recording: switch drafts, restore both carets and advance an option without changing the message

Not verified: macOS, Windows, Electron desktop shell, iOS, Android, remote/relay/tunnel connections, real queued-send/save persistence, permission revocation, attachment submission, or the provider-trait picker flow. Native mobile has a separate questionnaire. The synthetic question fixture is UI evidence, not a backend business-behavior test.

Implementation: GPT-6.1 Sol; tests: GPT-6 Astra; adversarial reviews: Claude Opus 5.5 and GPT-6 Sol, through Codex/Claude harnesses in T3 Code.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR adds a new message/question switching workflow to the production web composer, including draft and caret restoration across question progression and option selection. Because it changes central composer state and user-facing behavior across several interaction paths, human review is appropriate.

Walkthrough

The composer now keeps a message draft available while a pending question is displayed. Users can switch between editing the message and answering the question. The composer saves and restores the draft caret, and pending-question panels and blocking behavior follow the displayed question and answer mode.

Changes: Pending question composer

Layer / File(s)	Summary
Restore the message draft apps/web/src/composer-logic.ts, apps/web/src/composer-logic.test.ts, apps/web/src/components/chat/ChatComposer.tsx, apps/web/src/components/chat/usePendingThreadRequests.ts	ChatComposer saves the message draft target, text, and caret outside answer mode. composerStateForReturningDraft restores the saved caret and trigger when the target and text match; otherwise it uses the prompt-end state. Option selection clears prompt and cursor state only when the composer is answering pending input. Tests cover the restoration cases.
Pending question answer-mode controls apps/web/src/components/chat/ComposerPendingUserInputPanel.tsx, apps/web/src/components/chat/ChatComposer.tsx, apps/web/src/components/chat/ComposerPendingUserInputPanel.*.browser.test.tsx, docs/user/question-attachments.md	The panel accepts answer-mode state and a toggle callback. Its button switches between “Answer question” and “Back to message”; answering is disabled when responses are unavailable, while returning to the message remains enabled. ChatComposer wires the toggle and renders the panel for displayed questions. Tests and documentation cover the controls.
Pending-question presence checks apps/web/src/components/chat/ChatComposer.tsx	The drawer and blocking state follow displayed pending questions. Compaction is blocked when incoming pending user input exists, including when the message draft is active.

Merge Risk: Minimal · up to 2805b

The question controls and message draft can coexist without the investigated option click erasing the draft. The change is ready to merge after normal checks.

Security architecture risk: Low · up to 2805b

The change remains within the chat interface and preserves the existing permission checks. The main design risk is keeping messages, answers, and attachments associated with the correct request when users switch modes. No new permission bypass or cross-thread disclosure was established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated exposure is selection of message versus question state within the active chat environment and thread. The inspected transition does not establish additional service authority or cross-thread attachment access: answer state is keyed by environment, thread, and request, and attachment responses reconstruct question-specific targets.

Trust Boundaries and Controls

• observed — Both normal sending and pending-answer submission retain environment operation checks. Pending-answer submission also requires an existing resumable request and rejects an already in-flight environment/thread/request tuple. Keeping the panel visible in message mode does not itself invoke either command.

Resilience and Maintainability Implications

• observed — The existing response path releases its in-flight marker after a returned command result and reports non-interruption failures. Question attachment cleanup remains scoped to the current environment and thread and retains drafts for pending questions. Option selection now avoids resetting the message prompt and caret when the composer is not answering.

Merged upstream/main (70d60e03a7) in 45df8ce44b, so this is mergeable again. Two things had moved under it. #20161 took the question and approval handlers out of ChatView into usePendingThreadRequests.ts, so ChatView.tsx is back to upstream's version and the option-click caret guard now lives in that hook, where the handler reads composerRef. #20397 removed ChatComposer's manual memoization, so the Back to message toggle follows the file's useStableCallback shape; the shadow split, the panel sites, compaction and the caret effect merged by themselves. Two test files needed props: upstream's new ComposerPendingUserInputPanel.navigation.test.tsx gets isAnswering and onToggleAnswering, and this PR's permissions case gets upstream's cwd and threadRef. The diff against main is nine files (+174 −14).

Rerun on the merged branch: 274 passed across the seven test files, lint (only upstream's existing panel warning), format and the web typecheck clean. The dev desktop app checks in the description are from 2026-10-10 and were not retaken.

Merged upstream/main at 6a6ebb278d (2805b2d). #20870 moved the chat render tests into the browser project: upstream's deletion of ComposerPendingUserInputPanel.test.tsx is taken, and the Back to message permissions case is rewritten for the browser runner in ComposerPendingUserInputPanel.permissions.browser.test.tsx (it fails with the button's gate put back to upstream's). Unit tests (266 across four files), browser tests (5 across two files), lint, format and the web typecheck were rerun on the merged branch, and Verification in the body is updated. The dev desktop app checks were not retaken.

[juliusmarminge]

Taking over this one as maintainer. I’ll keep it focused on escaping question-answer mode without losing the message draft or caret, integrate current main, and verify both drafts in the client. Credit to @tiliakoos for the original fix.

[saphid]

Source-review concern at 9142af7: type a custom question answer, choose Back to message, then click an option in the still-visible question panel. In usePendingThreadRequests.ts, lines 414–419 skip displacedAnswer when the composer is in message mode, but lines 453–457 still call togglePendingUserInputOptionSelection, which returns customAnswer: "" for both single- and multi-select. The typed answer therefore has no preservation path in this sequence. Base always passed the displaced custom answer into the message before clearing it.

I see the PR describes replacement as intentional, but this conflicts with the user-text preservation behavior tracked in #12569. Please preserve user-authored answer text when selecting an option from message mode, or record the maintainer decision to change that behavior. A focused case should type the answer before toggling modes and assert where that text survives; the current case checks that the message stays intact.

This is a source-derived finding, not a reproduced UI failure. Independent exact-base/head execution remains unrun; no validation pass is claimed.

Note

Written by gpt-6.1-sol on behalf of Maria

updated this branch at c3c84a5a97, preserving @tiliakoos's commits and merging current main without rewriting history. the explicit mode toggle and separate draft carets remain. caret synchronization now uses one effect; obsolete tests follow main's deletion, with one focused regression added to the existing navigation suite.

@saphid's answer-preservation concern is addressed: choosing an option from message mode retains main's recovery of the custom answer and referenced contexts into the ordinary draft. only the answer editor's prompt reference and cursor reset are gated. @tiliakoos, thanks for the original toggle and draft-restoration work.

verification:

• the new regression fails on main and passes here. blacksmith vp run check:changed passed format, lint, both knip passes, affected typechecks, and all 3 browser tests.
• real codex request_user_input_async through the local web client: main hides the saved message with no return control; this head returns to it. message caret 15 and answer caret 4 survive switching, and typing inserts at each restored position. checked the 390px layout too.
• selecting pear from message mode recovered the custom answer into the message draft, submitted pear, and codex replied "pear.".
• two independent gpt-6.1-sol source reviewers approved this head. all 31 ci checks are green on the pushed head; gitcafe reports mergeable. no review bots were invoked.

media: both uploaded images loaded at 1440×1000; the uploaded recording played to the end and seeking worked. gitcafe renders these external embeds as links, so inline playback in its comment is unverified.

unverified: electron shell, native mobile, other providers, literal initial answers, attachment submission, revoked permissions, queued-message save, and remote/relay/tunnel paths. one answer caret snapshot remembers the current question; navigating away through other questions may return its caret to the end.
