Closes https://github.com/pingdotgg/t3code/issues/29202
With several pending line comments, Android's review sheet captures touch drags before they reach the comment list, leaving Submit review off-screen. Render the scroll content before the header's Compose controls in Android's native tree and reverse the column so the header still appears above the form, matching the existing commit-sheet pattern.
Implemented with Claude Opus 5.5 through Claude Code; reproduced, verified, and independently reviewed with gpt-6.1-sol through Codex.
POCO M3, Android 13, portrait. These captures use the production review sheet and native form-sheet presentation with six local fixture comments and mocked submission.
Before: two upward touch swipes leave the comments stationary and Submit review unreachable.

After: the same swipes reach the sixth comment and Submit review. Tapping it submits all six comments to the local fixture and dismisses the sheet.

A short review still fits its content and can submit with the test keyboard open.

TalkBack traversal on the same Android build reaches Cancel, the title, the subtitle, and Comment before the pending comments. No explicit traversal override was needed.

Not shown: real provider submission, full-size Gboard, other review-sheet integrations, or iOS runtime behavior. The iOS render order and layout are unchanged.

The Android review sheet reverses its column layout and renders its header after the content. On iOS, the header remains before the content.

Explanation
The description covers the problem, fix, linked issue, verification results, and test limitations. It includes before-and-after UI evidence. The issue's triage status is not established, and the agent details are not at the end.
Explanation
[#29202] PullRequestSheetContent renders the Android scroll content before the header in the native tree and reverses the column to keep the header above it. The existing scroll view contains the Android footer. Reported device verification shows that touch swipes reach all six comments and Submit review. The PR adds no automated regression test; the issue does not explicitly require one. The reported emulator verification predates the merge, but the merged diff retains the scroll fix.

Check TalkBack traversal for the Android sheet header.
The Android close control is an accessible wrapper rendered after ScreenContent in the native child hierarchy. android:flex-col-reverse changes its visual position but does not define accessibility traversal order. TalkBack may expose pending-comment descendants before the Close/Cancel control. Verify this order on Android and add explicit traversal ordering only if the issue occurs.

[gpt-6.1-sol][Codex] on behalf of shivam.
R1 checked on a POCO M3 running Android 13 at f9f277b7ffea0685bf063bb8e8bfa37d2738d421, using the production review sheet in the same native-sheet fixture with six local pending comments. With TalkBack enabled, the first forward swipe focused and announced "Cancel, Button". Subsequent swipes reached the title, subtitle, and Comment control before any pending-comment descendants. The proposed ordering problem did not reproduce, so I kept the existing sheet pattern without adding a traversal override.

d0aac795cf)The PR conflicted with main. Main's sheet refactor dropped presentation and the sheet's own NativeStackScreenOptions from this component. The merge keeps main's SheetHeader props and this PR's Android content-first order with flex-col-reverse, matching GitCommitSheet on main. vp run check:changed passes (format, lint, knip, typecheck, React Compiler). The emulator pass below ran on f9f277b and was not repeated after the merge.

Verified f9f277b7ffea0685bf063bb8e8bfa37d2738d421 on the t3 Android API 35 emulator with the matching cached native dev client, Metro, and an isolated dev server. Added real local projects, completed real Codex gpt-6.1-sol turns through the mobile composer, and loaded this PR through the server's GitHub adapter. No mocked providers, submission handlers, or showcase data.
Created six private line-comment drafts through the native diff UI. For the baseline, temporarily used the unchanged github/main version of PullRequestSheetContent.tsx (identical to the PR parent's component), then reopened the sheet. Two upward touch swipes left the first comments stationary and Submit review off-screen. Restored the exact PR component, reopened the same six drafts, and repeated the swipes: comment six and the enabled Submit review button became reachable while the header stayed above the list.
Also opened comment six from the scrolled sheet, saved it, and confirmed all six drafts remained. Cancel dismissed the review sheet and reopening preserved the drafts. The short empty review sheet rendered its footer and disabled submission correctly.
Before, baseline after two swipes:
Android baseline: six private drafts remain at the top and Submit review is off-screen
After, PR head after the same swipes:
Android PR head: comment six and enabled Submit review are reachable
Android PR head: touch scrolling from six pending comments to Submit review
No code changes or pushes were needed at f9f277b. Existing head checks report 29 successful, zero failing, zero pending. The component was restored byte-for-byte after the baseline comparison.
