A pending iOS autocorrection can arrive after Send clears the draft and put the whole message back in the composer. Draft clears now establish a reset generation synchronously. Native applies the clear even when editing has advanced, ends marked text, and drops callbacks from before that reset while retaining the stale-render checks.

Reset documents also bypass the native-echo mismatch check. This covers an attachment-only send when JS still sees an empty draft and a native keystroke is awaiting delivery. Ordinary echoes keep the mismatch check. CodeRabbit identified this case; the real-view harness fails on 14609bfa98ee25b6624993e1728ee3b1f48eb076 and passes with the follow-up.

Before, software key taps enter "Hello wrold"; tapping Send while "world" is the pending correction restores "Hello world" in the composer. iPhone 18 Pro simulator, iOS 27.0, English (India), autocorrection enabled, baseline 12ec17ce4c6481a8ea1049dedd78d0e56bc48aec.

After, software-key entry of Hello wrold, Fix wierd, Fix adress and Fix seperate, followed by Send with the correction selected and no trailing space, leaves an empty composer. The recording shows these sends and fresh typing, at 6x speed. A separate snapshot-checked pass restored New and Draft B independently when switching threads. Verified at 736248ede0feed2096f156034dc1b9c7a9d6a216, iPhone 18 Pro simulator, iOS 27.0, monolingual English (India), autocorrection enabled. Native fingerprint ad96c4f9db7c117533b6dbb1344cad516c914aae, built on shiv, with Metro and an isolated Replay (dev) backend on corex.

The harness covers correction racing a clear, marked composition, echo resets, stale updates and fresh typing. The echo-reset case failed on 14609bf with An echo-marked reset retained an undelivered keystroke: x, then passed on d95da69.

The reset design passed two independent Codex review rounds before the native-echo follow-up. The harness covers autocorrection racing a clear, marked composition, attachment-only echo resets, typing after reset, stale updates, ordinary mismatched echoes, and lower-generation draft switches.

The native editor is also keyed by draft identity, so a pending callback from one draft cannot write into the next selected draft. A React integration test fails on d95da693870ddc73951a254004e98df09a790b1e with expected Draft A corrected to be Draft B and passes at 36aae639070cf6fb09e19e4ad80cc54cbfd35d7d. The test remains green at the current head.

This fixes the draft clear. The outgoing message can still contain the JS snapshot from before native autocorrection. Keystrokes before native applies the clear are discarded. Physical iPhone and Android runtime behavior remain unverified. Web and Android ignore the optional reset reader.

Base update audit

Merged main 4b87a45770d24a47f7e6bc40e3f19011e41c7724, giving PR head 736248ede0feed2096f156034dc1b9c7a9d6a216. The overlapping change replaces instanceof ComposerDraftPersistenceError with Schema.is in the draft-hydration error handler. It leaves the send/reset path unchanged. The clean merge matches the merge-tree result. The native editor, iOS wrapper, reset handlers and regression tests are unchanged from c2cda99.

The changed-file checks pass under the new Effect compiler checks. The real-view UIKit harness passes on shiv. A matching iOS simulator build completed at this head with fingerprint ad96c4f9db7c117533b6dbb1344cad516c914aae.

The final-head device pass succeeded after installing the cached native client before opening any app in the new device lease. The four pending-correction cases above passed. This includes the exact spellings from #31210. The same-batch regression test covers its reported event ordering, where clear and the newer native event arrive before an empty render.

At 736248ede0feed2096f156034dc1b9c7a9d6a216, CI run 41939235777 and Native fingerprint diff run 41939235959 completed successfully. Macroscope approved this head. The final-head device evidence above covers the fresh native build and the duplicate report.

Implemented with Opus 5.5 in Claude Code and GPT-6.1 in Codex; investigated, tested and reviewed with GPT-6.1 in Codex.

Walkthrough

Draft clears now increment a reset generation that reaches the iOS native editor. The editor applies newer generations despite stale event counts, ends active composition, and tags native events with their generation. React and Swift tests cover clears, stale events, composition, and later typing.

Changes: Composer reset handling

Layer / File(s)Summary
Track and pass draft reset generations
apps/mobile/src/state/use-composer-drafts.ts, apps/mobile/src/native/T3ComposerEditor.types.ts, apps/mobile/src/components/ComposerEditor.tsx, apps/mobile/src/native/T3ComposerEditor.tsx		Draft clear operations increment a per-draft reset generation. ComposerEditor passes a reader for that generation through the native editor interface.
Apply and acknowledge generation-aware updates
apps/mobile/src/native/composerEditorRevision.ts, apps/mobile/src/native/T3ComposerEditor.ios.tsx, apps/mobile/modules/t3-composer-editor/ios/T3ComposerEditorView.swift		Controlled documents and native events carry reset generations. The native editor applies documents with newer generations despite stale event counts, and the JavaScript editor rejects events from older generations.
Test reset and stale-event behavior
apps/mobile/src/components/ComposerEditor.ios.test.tsx, apps/mobile/modules/t3-composer-editor/tests/ios/main.swift, apps/mobile/modules/t3-composer-editor/tests/run-ios.sh, apps/mobile/vite.config.ts		React and Swift tests cover clears, stale event counts, draft switching, IME composition, and subsequent typing. The iOS test runner compiles and runs the Swift tests.

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

Full details: Linked Issues check

Explanation

Issue #30167 requires that a send right after a final-word autocorrection clears the composer, and that the corrected text does not reappear. The previous assessment found this met by the reset-generation logic. The incremental diff from previous reviewed head a80dbed8 to c2cda999 shows no change in composerEditorRevision.ts. In T3ComposerEditorView.swift, the only incremental hunk changes paste routing. It does not touch the reset, marked-text, or stale-event paths that implement the objective. The React and Swift harnesses that cover these paths are unchanged in the inspected evidence. Other incremental paths (for example T3ComposerEditor.ios.tsx and use-composer-drafts.ts) were not inspected because the diff output was limited. The prior conclusion is preserved for those paths on the basis of the unchanged reset-path evidence.

Full details: Out of Scope Changes check

Explanation

The incremental change in apps/mobile/modules/t3-composer-editor/ios/T3ComposerEditorView.swift adds a new branch in ComposerTextView.paste. When the pasteboard has exactly one item and T3ComposerClipboard.hasThreadLink matches its text, the branch calls onPasteContext instead of super.paste. The inline comment describes multi-item pasteboard handling for thread links. Issue #30167 concerns autocorrection and composer clearing after send. The PR description and PR objectives do not mention paste routing or thread-link clipboard handling. The branch changes user-visible paste behavior without a connection to the linked objective. No paste-routing test is described in the PR summary. The diff for the other incremental paths was not inspected, so further out-of-scope changes cannot be excluded.

Resolution

Remove the thread-link paste-routing branch from ComposerTextView.paste in apps/mobile/modules/t3-composer-editor/ios/T3ComposerEditorView.swift from this pull request. If the paste behavior is required, move it to a separate pull request that links its own issue and includes its own harness coverage. Then confirm that the incremental diff contains only composer reset and echo changes.

Full details: Description check

Explanation

The description covers the problem, the change, and verification in detail. It describes the iOS autocorrection race that restores a cleared draft, the reset-generation fix, the native-echo follow-up, and the draft-identity keying. The Verification section lists focused tests, a UIKit harness run, a check:changed summary, device evidence with before/after recordings, and a list of what remains unverified. It states the physical iPhone and Android behavior is not verified. Two gaps remain. First, the Scope and approval section is missing. The template asks for a linked triaged issue or maintainer-approved discussion. The description links issues #30167 and #31210 in the header, but it does not state whether they are triaged or cite a maintainer approval comment. Second, the description is long and mixes in CI run links, fingerprints, and audit notes. Those details do not follow the template's request for a focused account, and they make the required sections harder to find. The author did include a model and harness note at the end, which the template requests.

Resolution

Add a "Scope and approval" section, or fill the existing one if it is missing. Link the triaged bug issues (#30167 and #31210) and state whether a maintainer approved the direction and scope, with the approval comment link. The PR is a bug fix, so explain briefly why it qualifies under the fix rules. Keep the Problem, Change, and Verification sections focused. Move long audit trails, fingerprints, and CI details into a short summary or a linked comment, so reviewers can find the required sections quickly.

Apply reset documents even when the previous value was a native echo.

The explicit discard path dismisses the editor before it clears the draft. The same failure remains reachable when an attachment-only message is sent while a native keystroke is still awaiting JavaScript delivery. The send guard allows the empty text because an attachment is present. The reset can then be classified as a native echo, so the mismatch check leaves the keystroke in the native editor. JavaScript drops the old-generation event, and the next edit can republish the retained text.

Skip the echo mismatch check for reset documents. Keep the check for non-reset echoes. Add a harness case for an attachment-only send with an undelivered native keystroke.

The new real-view harness case fails on 14609bf with An echo-marked reset retained an undelivered keystroke: x and passes after the fix. It also checks that typing starts from empty and that an ordinary mismatched echo preserves newer native text. vp run check:changed passes.

The updated PR evidence records the original autocorrection send on the matching final iOS build.

CcoderabbitaiBot7d ago

@shivamhwp The supplied code confirms that reset documents bypass the native-echo mismatch check. Non-reset echoes retain the check.

Your reported harness results cover the undelivered keystroke, typing after the reset, and preservation of newer native text. This addresses the finding.

Macroscope's review found this PR approvable — The iOS composer now tracks draft resets so delayed autocorrect events cannot restore text after sending or discarding. The change is limited to editor synchronization and leaves existing persistence and attachment cleanup behavior unchanged.

Key the native editor by draft identity.

When the selected draft changes, a pending event from the previous native editor can pass acknowledgeComposerNativeEvent and reach the current onChangeDraftMessage callback. That callback writes to the current draft, so an event from draft A can overwrite draft B's text. Include the draft in the native child key so each draft has a separate native editor session.

  • fix(mobile): isolate native composer events between drafts36aae63
Sshivam7d ago

[GPT-6.1][Codex] on behalf of shivam.

Fixed the draft-identity follow-up in 36aae639070cf6fb09e19e4ad80cc54cbfd35d7d. The native child key now includes the draft key, so an old native view cannot deliver its queued event through the next draft's callback.

The integration test delivers a pending event after switching drafts. It fails on d95da69 because "Draft A corrected" overwrites "Draft B", and passes with the fix. vp run check:changed passes. On the final iOS client I repeated the autocorrection send and checked that two threads restore their own drafts. The refreshed evidence is in the PR body. The native source and fingerprint are unchanged from d95da69.

[GPT-6.1][Codex] on behalf of shivam.

Merged current main bb4afa5425c52104a9261fa2d022cb8ba2fcc099; the PR head is now c2cda9990ca31c01b6a6fb3d47fde3384aef1c3a. The fix still applies. Incoming native paste handling required one clipboard stub in the real-view UIKit test harness.

Not ready yet: the new integrated device pass is blocked by device support. The iPhone 18 Pro simulator opened in the Device panel, but screenshot failed with Could not communicate with device support. Try refreshing devices. I refreshed devices and retried once; it failed identically. AgentDevice's Settings launch also failed with Daemon request timed out, diagnostic mw1ryw7y-701399e6. I stopped verification under the device tooling rules and released the lease. No new device recording exists for this build. The earlier before/after evidence in the body remains labeled with its actual commits.

The new native build is cached for a resumed device pass. The isolated servers, simulator lease, temporary checkout and test data are cleaned up. Physical iPhone and Android runtime behavior remain unverified.

The device blocker cleared. I verified the rebuilt iOS client at c2cda9990ca31c01b6a6fb3d47fde3384aef1c3a, native fingerprint 8d6b451f01590dcf5169f0dc32e98a363cba1bd1, on an iPhone 18 Pro simulator running iOS 27.0. Metro and an isolated Replay backend ran on corex. With monolingual English (India) and autocorrection enabled, software-key taps entered Hello wrold, world was selected in predictions, and Send without a trailing space left the composer empty after the response. Fresh software-key typing produced New, and switching between two threads restored New and Draft B separately.

Live ready check: head c2cda9990ca31c01b6a6fb3d47fde3384aef1c3a, current main/base 8b44f42b14c8e273156474a924ccf29680dd7857. Main's 10-file diff-preview update does not touch the composer, native inputs or command execution; the merge-tree check is clean. Macroscope approved this head, CodeRabbit passes, and no review finding is unresolved. The PR is open, not a draft, and mergeable. Auto-merge is off and there is no merge queue entry.

The installed app, simulator lease, isolated backend and Metro are cleaned up. Physical iPhone and Android runtime behavior remain unverified. The outgoing message can still use the JS text before autocorrection, and a reset intentionally discards typing before native applies it. This change fixes the composer clear. It is ready for Shivam's review and merge.

[GPT-6.1][Codex] on behalf of shivam.

Merged current main 4b87a45770d24a47f7e6bc40e3f19011e41c7724 into the PR. Head is 736248ede0feed2096f156034dc1b9c7a9d6a216. The only overlapping source change is Schema.is(ComposerDraftPersistenceError) in the hydration error handler. It leaves the send/reset path unchanged, and the merge matches the clean merge-tree result.

CI run 41939235777 and Native fingerprint diff run 41939235959 completed with success at this head. Macroscope approved this head. Required checks are satisfied.

The new device pass is blocked by device ownership tooling. I opened an iPhone 18 Pro simulator, configured English (India), and attempted to install the matching client through its bound AgentDevice command. Install failed with DEVICE_IN_USE, identifying this task's own session t3-e6cccd and workspace as owner, diagnostic mw2sstkd-e3a29efd. I followed its hint to inspect the owner with device status. The bound command refused because device status reads the local machine's claims, not the device host's. I stopped verification under the device tooling rules, released this task's lease and cleaned up the isolated servers, data, temporary native checkout and temporary files. No new app recording exists at this head. The previous recording remains labeled c2cda99 in the body.

Added #31210 to scope as a reference. Its trace matches the existing same-batch regression, but its exact pending-correction cases Fix wierd, Fix adress, and Fix seperate remain unverified on the new head. I will add Closes https://github.com/pingdotgg/t3code/issues/31210 only after those device cases pass. Physical iPhone and Android runtime verification remain outstanding.

[GPT-6.1][Codex] on behalf of shivam.

The final-head device pass now succeeds. I installed the cached client before opening any app in the fresh lease, avoiding the previous ownership error. Verified head 736248ede0feed2096f156034dc1b9c7a9d6a216, native fingerprint ad96c4f9db7c117533b6dbb1344cad516c914aae, iPhone 18 Pro simulator, iOS 27.0, monolingual English (India), autocorrection enabled, Metro and isolated Replay (dev) backend on corex.

Every trigger was entered by tapping the software keyboard. Send was tapped with the correction selected and no trailing space:

text
1PASS Hello wrold -> world: composer empty after Send and response
2PASS Fix wierd -> weird: composer empty after Send and response
3PASS Fix adress -> address: composer empty after Send and response
4PASS Fix seperate -> separate: composer empty after Send and response
5PASS fresh typing: New, with none of the sent text
6PASS switching threads: New and Draft B restored independently

The body embeds the final screenshot and recording at 6x speed. The recording covers the four sends and fresh typing; the later thread-switch checks passed in snapshots and I inspected the final Draft B screen. This supports adding Closes https://github.com/pingdotgg/t3code/issues/31210. The same-batch integration regression covers its trace ordering. The earlier blocked device report is superseded.

Local checks, real Swift UIKit harness and native build results at this head passed. CI run 41939235777 completed successfully; all eight required checks are satisfied, with two correctly skipped jobs.

Physical iPhone and Android runtime behavior remain unverified. The outgoing message can still use the pre-correction JS snapshot. The reset discards typing before native applies it. This fixes the composer clear.
