fix(web): an image-only send that fails behind a new draft now says so - #32732
When the first message of a new thread has only an image and its send is interrupted by a dropped connection while I have already typed my next message, the message leaves the thread with no word at all: no row, no toast, no banner. I should be told it may not have been sent, as I am for a failed text message.
Change
The failure toast for a send that fails behind a new draft now also shows when the failed message has only images. It says "Message may not have been sent" for an interrupted send or "Message not sent" for a rejected one, with "Your new draft was kept." and no Copy action, since there is no text to copy.
Scope
A bug fix: a failed send that vanishes with no notice. Refs #35001; #35102 fixed the rest of that report, the failed message staying in the thread and the text case. One function in useComposerSend.ts plus one browser test.
Verification
To see it on Linux web (main 77d3358a1f, Replay provider):
Open a new thread, attach an image and type nothing.
Pause the server process (kill -STOP <pid>), press Enter, then type next draft.
When "reconnecting" shows, the image message is gone and nothing says so.
An AI agent (Claude Opus 5.5) ran those steps in T3 Code's Browser panel, one fresh dev server per revision, main 77d3358a1f (which contains #35102) first, then 7271753c8d, this branch with that main merged. Stand-ins: the paused server process stands in for a dropped connection, and the Replay (dev) provider scripts the replies for the thread used to set up. On main the image send vanishes with no notice. On 7271753c8d the toast "Message may not have been sent" / "Your new draft was kept." shows with no Copy action, and next draft stays.
Main 77d3358: after the interrupted image-only send, no message, no notice and no image are left; next draft is in the composer while the client reconnects.
7271753: the same send shows the toast Message may not have been sent with Your new draft was kept., no Copy action; next draft is in the composer.
Claude Opus 5.5, as a separate AI agent session, ran vp run scenarios:prove with a local one-test scenario of these steps: it fails on main 77d3358a1f and passes on 7271753c8d.
Re-checked 2026-11-14 (UTC) on 7271753c8d, which merges main 77d3358a1f: these steps, the scenario, the browser test and vp run check:changed give the results shown here.
Not checked: a real provider turn (Replay scripts it) and a real network drop (a paused server process stands in); desktop and mobile (the change is in the web composer the desktop app wraps).
Details: method, server records, tests
Method: each server ran from source in a sandbox with a fresh test home, "Test machine" as its name, a synthetic one-commit demo-project, and the free Replay (dev) provider. Input came from T3 Code's Browser panel (Chromium, a private profile) at 1280x800, reaching each server through a local port forward. A "Say hello" turn first made the project ready; then a new thread got sample.png (a small synthetic PNG) and no text. The server process was paused with SIGSTOP before Enter, next draft was typed, the page was read about 4 s after "reconnecting" showed, and the server was resumed with SIGCONT.
The server's record of the two launches on main 77d3358a1f (the second is the image-only send):
$ sed -n '/^## server trace/,$p' panel/evidence/main-record.txt | sed 1d
13:41:41.940 launchThread e88c7027 Success

13:43:48.657 launchThread 494ac222 Success
13:44:37.642 launchThread 5c21ec55 Interrupted
The browser test in apps/web/src/components/ChatView.browser.test.tsx sends an image-only first message from a new thread's draft, holds the launch, types a new draft, ends the launch with an interrupt, and expects "Message may not have been sent" with no Copy action. answerRpc in apps/web/test/fakeEnvironment.ts lets the test answer the launch and the upload. 7271753c8d's test files against main 77d3358a1f's production useComposerSend.ts:

On main the test waits for that toast until the 15 s test timeout. With a 5 s limit on that one assertion (a diagnostic copy, not committed), it fails there:

…poser has new text
When a send failed after the user had started typing the next message, the
failed message stayed in the timeline as if it had been sent, because its
optimistic row was only removed when the draft could be restored into an
empty composer.
The failure path now always removes the optimistic row and releases its image
previews. The draft is still restored only into an empty composer; otherwise
the new draft is kept and an error toast offers "Copy message" so the failed
text is not lost. The toast also shows when a dropped connection interrupts
the send, which shows no thread error.

Macroscope's review found this PR approvable — Failed sends now remove ghost messages while preserving newer composer text and offering a persistent copy action for the failed text. The change is limited to client-side failure recovery, with clipboard access only on explicit user action.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Failed sends remove the optimistic message and release its previews. If the composer contains newer content, the send handler preserves it. Failure notices distinguish interrupted sends and other failures, and offer a copy action when the failed message contains text. Browser tests cover rejected and interrupted dispatches.

Summary
Failure handling and copy action apps/web/src/components/chat/useComposerSend.ts
Failed sends remove the optimistic message and release its previews. The sent draft is restored only when the composer is empty. Otherwise, newer content remains. When sent text is not restored, the failure notice stays open and offers a copy action. Clipboard failures show an error toast. A fallback notice distinguishes interrupted sends from other failures.
The fake environment can temporarily register an RPC handler and restore the prior handler on disposal. Browser tests cover rejected and interrupted sends with text and image-only inputs. They check draft preservation, failure notices, the provider error banner for rejections, and copy actions for text.
pingdotgg/t3code#24659 — This change updates failed-send handling when newer draft content exists. It does not implement the issue’s requested retry with the same command ID.
Suggested reviewers:juliusmarminge, t3dotgg
Merge Risk: Low · previous review f5c42
Failed sends from new threads have a copy action, but the tests would not catch its removal. The change is mergeable with that bounded coverage gap, though a browser assertion would protect this recovery path.

Explanation
The title names the actual change: a failed image-only send behind a new draft now shows a notice. It matches the raw summary, which describes a fallback toast for attachment-only failures in useComposerSend.ts. The title is specific and uses the conventional commit form. It omits the interrupted vs. rejected distinction, which is acceptable.
Full details: Description check
Explanation
The description follows the template's main sections (Problem, Change, Scope, Verification) and fills each one with specific content. The Problem names the failing case: an image-only first message in a new thread whose send is interrupted while a new draft is typed. The Change explains the toast text and the absence of a Copy action. Scope links #35001 and #35102 and explains that the change is one function plus one browser test. Verification gives reproducible steps, before/after screenshots, server trace records, test output, and a list of what was not checked. The template's closing request for the agent model and harness is met by the 'Generated with Claude Opus 5.5 and GPT-6.1 Terra' line. Minor gaps: the Verification section is long and heavy with raw logs, and the Scope section does not explain why the issue is a bug fix rather than a feature beyond one sentence. These gaps do not make the description incomplete.

Keep the attachment-only failure toast open
If an attachment-only send fails after the user enters a new draft and navigates away, the existing failure toast closes after five seconds. The generic persistent toast is suppressed, and the failed optimistic message is removed. The user can miss the failure and lose the indication that the attachment was not sent.

Re the outside-diff finding in this review: fixed in 842e05d. The "Could not start thread" / "Background task failed" toast now uses timeout: 0 whenever the failed message was not restored to the composer, so an attachment-only failure stays visible after navigating away. When the draft was restored, "Open draft" recovers it and the default timeout stays. "Copy message" is still added only when there is text.
…t sent
An interrupted dispatch only means no acknowledgement arrived; the server
may still have taken the message. The toast for that case now reads
"Send not confirmed" and asks to check the conversation before sending
again. A rejected send keeps "Message not sent".

Send from a new draft, type a later draft, navigate away, and reject the pending send. Assert that “Could not start thread” copies the failed text and preserves the later draft. The existing test covers only the separate generic-toast action, so it cannot catch a missing secondary action here.

… was not confirmed
When nothing was typed during the send, an interrupted send went back into
the composer with no notice, so it looked ready to send again even though
the server may have accepted it. It now shows the same "Send not confirmed"
warning, without the new-draft line or a Copy action, and it stays until
dismissed.
The failed-send browser test gains text and image-only rows with nothing
typed meanwhile, and a new test covers the "Could not start thread" toast's
Copy message action for a new thread rejected after leaving its draft.

Re the nitpick in this review: covered in 7b945f3 by a new browser test. It sends from a new thread's draft, types a later draft, switches to another thread and rejects the launch. It then checks that "Could not start thread" offers "Copy message" with the failed text and that "Open draft" shows the later draft. It fails on main at the Copy click.
merged current main into the branch with a merge commit (4b70cd0), no rebase. the only conflict was ChatView.browser.test.tsx, where main added the older-settled thread menu test beside this pr's failed-send tests; both are kept unchanged. no source changes.
vp run check:changed passed format, lint, knip and typecheck through blacksmith. ChatView.browser.test.tsx passed 8/8 on the merged head. all earlier review findings were already fixed by the contributor.
Verified in a real dev environment
verified unchanged head 7b945f331eee978aa2a9e491b84fcd4df7c6c900 on a linux boat vm. used repository playwright with /usr/bin/google-chrome, isolated development state, and real codex gpt-6.1-sol turns through the web composer. created the git projects and threads through the app. no replay provider, mocked transport, or seeded fixtures.
reproduced first on github/main at cec8d73a1f: paused this task's server process before sending, typed next draft, and waited for the client to interrupt the request. the failed optimistic message remained in the timeline. stopped main's server before starting the pr server.
the same sequence on the pr removes the failed row, preserves next draft, and shows the persistent "Send not confirmed" warning. "Copy message" copied the exact original text. the warning remained visible well beyond the default toast duration.
nearby checks passed: a normal send after reconnect returned NEIGHBOR-OK from codex; an interruption with an empty composer restored the original text, showed the uncertainty warning without a copy action, and removed the optimistic row. after reconnect, that original request actually arrived and codex replied RESTORED-DRAFT, confirming why the warning must preserve uncertainty. the script pressed send only once for that request.
short runtime transcript:
main interrupted send: timeline user rows = READY prompt, FAILURE-CHECK prompt
main composer: next draft
pr interrupted send: timeline user rows = READY prompt
pr composer: next draft
pr clipboard: Reply with exactly FAILURE-CHECK. Do not use tools or change files.
normal send after reconnect: NEIGHBOR-OK received
empty-composer interruption: original draft restored, warning visible, copy actions = 0
after reconnect: original RESTORED-DRAFT request arrived and received a real codex reply
before, main:
after, exact pr head:
14-second recording of the interruption transition, at original speed with startup trimmed. inspected the uploaded clip in t3's browser player, including playback to the end and seeking.
existing focused checks passed through blacksmith-check: cd apps/web && vp test run src/components/ChatView.browser.test.tsx, 7/7 tests, exit 0. github's product ci is green at the exact head. no code was changed, so no new commit or push was needed.
Not verified
native desktop, ios, android, other providers, and remote relay/tunnel connections. confirmed-rejection, attachment-only, and navigation-away recovery were not induced in the live app. no source changes were needed.
Thanks @maria-rcks for testing this with real Codex turns. Our own run used the Replay provider, so yours is the first check against a live one. You reproduced the ghost row on main and confirmed that the PR removes it, keeps next draft and copies the exact failed text.
Your empty-composer case also showed that the interrupted request can still arrive after reconnect on this branch, where our capture only saw that on main. That is the case "Send not confirmed" exists for: Codex replied RESTORED-DRAFT even though send was pressed only once, so the reply came from the original request.
useComposerSend.ts takes main's text, since its conflicts are the lines pingdotgg#35102 fixed and this branch's other changes to the file depend on them; the test file keeps both sides' imports.
…say so
main now removes a failed message and offers its text when a new draft was typed
(pingdotgg#35102), so this branch's tests for that behavior go. The one case left: a new
thread's first send with only an image, interrupted by a dropped connection,
vanishes with no notice. The test holds the launch, types a new draft, ends the
launch with an interrupt, and expects the warning with no Copy action.

When a send with only an image failed while a new draft was in the composer,
its message left the timeline with no toast, so an interrupted first send of a
new thread vanished without a word. The failure toast now shows for it too,
without a Copy action since there is no text.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
I merged main to clear the conflict (useComposerSend.ts takes main's text, which #35102 fixed), and this branch now carries only the case #35102 leaves: an interrupted image-only first send of a new thread showed no notice and now shows the failure toast.

I moved this branch from c1ff800 to 7271753: I merged main to clear a conflict with #28780 in the imports of ChatView.browser.test.tsx, keeping both sides.
Real Chromium web client, 1280×800, light theme; fresh synthetic data and Replay (dev) Showcase on both commits.
Paste an image with empty text and let its upload finish. Pause the server, press Enter, type next draft, wait for reconnecting, kill the paused server to lose the buffered launch, then restart and reconnect. Capture after another 8 seconds.
Proven: the scenario fails on base and passes on head; scenarios:prove exited 0. Base silently removes the image. Head shows the failure notice, preserves the newer draft, and offers no Copy action. The notice remains through another ten seconds and can be dismissed without losing the draft.
A server-rejected send was not exercised in the controlled paired proof. An earlier attempt produced Message not sent on head from an attachment-upload failure, but the final comparison specifically proves the interrupted-launch path.

Problem
When the first message of a new thread has only an image and its send is interrupted by a dropped connection while I have already typed my next message, the message leaves the thread with no word at all: no row, no toast, no banner. I should be told it may not have been sent, as I am for a failed text message.
Change
The failure toast for a send that fails behind a new draft now also shows when the failed message has only images. It says "Message may not have been sent" for an interrupted send or "Message not sent" for a rejected one, with "Your new draft was kept." and no Copy action, since there is no text to copy.
Scope
A bug fix: a failed send that vanishes with no notice. Refs #35001; #35102 fixed the rest of that report, the failed message staying in the thread and the text case. One function in
useComposerSend.tsplus one browser test.Verification

Stand-ins: the paused server process stands in for a dropped connection, and the Replay (dev) provider scripts the replies for the thread used to set up. On main the image send vanishes with no notice.
