feat(mobile): rebuild the pull request tab around what blocks the merge - #36999
On your phone, the Pull Request tab used to be one long list of everything. Now it answers "can I merge, and what's stopping me?" One row per blocker (checks, unresolved threads, approvals, conflicts) opens the screen or sheet that fixes it. Merging, picking reviewers and creating a PR each happen in a small sheet, and creating a PR no longer throws you out to the browser.
Header: state pill, number, author, "updated 4m ago", title, head → base.
Gate rows: checks (failing / running / passed), unresolved threads (with "1 from a bot"), approvals, conflicts. The checks row opens Checks, the threads row opens Comments and the approvals row opens Reviewers.
GitHub doesn't report the required approval count, so the row says "N approvals", and reviewDecision plus requested reviewers decide the tone and subtitle.
Conflicts only turn green on GitHub's word; UNKNOWN shows "Checking for conflicts".
A changes card (files, +/−, viewed progress, comments on files). It only appears when the host sends files.
A collapsed description with Show more and Edit.
An empty state ("No pull request yet", with "N commits on are ready to go into ") and Link an existing pull request.
A foot action under the gates: Merge (opens the sheet), Merge when ready, Will merge when ready · Cancel, with "Can't merge yet:" above. In the hub it shows only while feat(mobile): one next-step bar under both Source Control tabs #37104's next-step bar is on a local step (commit, push), so Merge stays reachable; the diff-review dock always shows it, with Create pull request when there is no PR.
Checks screen (PrChecksScreen.tsx, PrCheckFailureRow.tsx), one plain list with no cards
A thin red/amber/green bar and "1 failing · 1 running · 11 passed" at the top.
Failing rows: name, "Failed after 4m 12s", then the first annotation (path:line, test, message) indented under a thin red rule, and exactly two actions, Fix with AI and Rerun. View log, Copy error and Open on GitHub sit in the row's ⋯ menu. Only the first 3 failures prefetch details; details are cached per PR.
Running rows say Queued or In progress and open the run. The checks list carries no start time, so there is no elapsed time yet.
Passed checks fold into one "N passed" row that expands in place. Display uses desktop's shared check verdict, so action_required shows as failing.
Comments screen (PrCommentsScreen.tsx, PrThreadRow.tsx, PrThreadScreen.tsx), a conversation list
Unresolved N / All N is a segmented control. Hide bots moves into a filter button in the top bar, whose menu also holds Refresh until polling lands in the stacked PR.
Each thread is a plain row: coloured initials, name, time, a severity pill for bot findings (CodeRabbit's "🟠 Major"), ⋯ (Open on GitHub; Edit/Delete on your own conversation comments), then the file:line as a quiet link, the body, the latest reply on one line, and text links Reply and Resolve.
Tapping a thread opens a Thread screen over the list: the file link, the conversation as messages, Resolve top right and a pill "Reply…" box (focused when you came from Reply). Back returns to the list.
The list keeps a pill "Comment on #N…" box. MessageBox gains an inline layout for these one-row composers.
A comment's file:line opens that file in the app's diff (openDiffForFile, branch area) from the hub; the dock falls back to GitHub.
PullDownMenu now opens upward when its button sits in the lower half, shows a check for checked items, and claims the page's Back so Android Back closes the menu instead of the screen.
Merge lists only the methods the repo allows (resolveGitHubPRMergeMethods), starts on the default, and always sends the method. Previously mobile could only merge with the default.
Reviewers: search to add, ✕ to remove.
Edit title / description (description through github.updatePR, which now forwards prRepo for fork PRs).
Create pull request: title and description seeded from the branch's commits, Write with AI (git.generatePullRequestFields), a base picker (repo.searchRefs) and Create as draft.
It pushes first if needed, through the existing hosted-review create intent.
It lands on the PR tab for GitHub. The other four providers get the existing Created notice with its Open link; nothing opens the browser by itself.
The Changes tab's Create PR button, the action-sheet rows and the PR empty state all open this sheet.
It can't be dismissed while it is creating, and closing it cancels a running Write with AI.
Sheets close themselves when the worktree, branch or PR they were opened for changes.
Shared with desktop (no desktop behaviour change)
src/shared/hosted-review-create-seed.ts (moved from right-sidebar/create-review-draft-title.ts) gains resolveCreateReviewSeedFromCommits, GitHub's own default:
one commit gives its subject and body;
several give the humanized branch title and a list of commit subjects;
any merge in range falls back to the branch seed.
normalizeCreateReviewBaseSearchResults moves to src/shared/hosted-review-refs.ts.
TEXT_GENERATION_CLIENT_TIMEOUT_MS (75 s) is shared by desktop's three generation calls and mobile's.
MountedBottomDrawer gains dismissible (Back, backdrop and drags leave the sheet up) for the running Create.
Next-step bar (#37104): useMobilePrTab takes the bar's shared PR actions engine and agent launcher, so both agree on in-flight state. The bar's Merge opens the Merge sheet (new optional onMerge on useMobileSourceControlNextStep), its Create reaches the Create PR sheet through createPrAction, and Checks and Comments are pages on the hub pager (SourceControlHubScreen gains 'checks' | 'comments'). The Checks fix prompt reuses buildPrFixChecksPrompt.
Why
The approved mock (1 Nov) makes the PR tab a decision surface: blockers first, each resolved where you tap it. Today's tab stacks every section with big Close/Unlink buttons at the top, has no way to pick a merge method, and creates PRs titled with the branch name before sending you to the browser.
The rules come from desktop rather than mobile copies:
merge state (resolveGitHubPRMergeState), merge methods, check verdicts, comment grouping and bot detection were already shared;
the create seed, base-search normalisation and generation timeout are moved to src/shared here.
The commit-based seed lives in shared code next to desktop's branch seed, so desktop can adopt it later without a second copy.
Linked Issue
No issue. This is the approved Source Control redesign ("Pull request", "Checks and comments" and "Sheets" in the 1 Nov mocks). Mark as draft (needs a new host method) is a separate host PR, and polling, thread code lines and "Ask to fix" follow in a stacked PR.
Visual Proof
Captured from the page bundle with scripted host replies (same demo data before and after), iPhone 15 size, dark.
Before (main)

Checks and Comments, before and after. On main they are sections of the one long PR tab (left two columns); here each is its own screen.

Testing
Rendered every state above from the built page bundle with the capture rig (scripted host replies, no page errors), and compared it with the same rig on main.
Mobile typecheck (tsconfig.json, tsconfig.test.json, tests-typecheck ratchet).
Focused vitest: components, source-control, session, tasks and the RPC recording goldens (6425 tests), plus every dependent test from test-dependents.sh (160 files).
Root tests for the moved shared modules and the desktop importers.
verify:mobile-localization, verify:mobile-localization-coverage, check:code-quality:changed, check:react-doctor:changed, audit:anti-slop and check:max-lines-ratchet.
build:mobile-web: 181 assets (main 184); 9,482,917 code bytes, under the 9.5 MiB fence.
New tests: the gate rules (pr-tab-gates.test.ts), the bot severity marker (pr-comment-severity.test.ts, including identifiers it must ignore), the shared commit seed (hosted-review-create-seed.test.ts), and the linear-only seed boundary (mobile-git-history.test.ts). Each fails on the code it replaces.
Not tested on a device or simulator.

Review
Four review rounds (Codex and Claude) plus a check of the last round's fixes. Rejected or deferred:
Seed commits beyond linear history: rather than trying to find the base boundary from git.history (whose mergeBase is against the upstream, not the PR base), any merge in range falls back to desktop's branch-name seed.
Removing the header's now-unused onOpenPrWeb/prNumber props: left alone for sc-hub-changes, which owns that header.
Checks/Comments redesign: four more rounds. Fixed: an iOS 15.1–16.3 parse failure from a regex lookbehind, menus running off-screen near the bottom, Android Back skipping the menu, errors hidden under the Thread screen, aria-disabled leaking onto conversation rows, a tap through a closing menu opening a thread, Copy error feedback, Delete busy state, and a thread reappearing after a failed refresh. Follow-up: the covered Comments list stays keyboard-focusable behind the Thread screen, as the hub does under its own overlays.
Agent skill upstream boundary
Not applicable, or this change copies or mechanically translates no upstream skill-installer source, tests, fixtures, registry entries, path tables, comments, or documentation.
Notes
Mixed versions: every new read is optional. Older hosts without files hide the changes card; without git.generatePullRequestFields the sheet shows the host's error; git.historymessage is optional.
Mobile outside the PR tab: the diff-review dock still mounts the same tab and gets its own ⋯ menu (Refresh even without a PR) and Back handling.
Desktop: behaviour is unchanged, apart from importing the moved shared modules. Desktop can adopt the commit seed later.
Folder workspaces and non-GitHub repos: the PR tab still shows "Hosted review panel unavailable"; Create works for all five providers.
Shipped shells: no native routes or native code changed; everything is in the over-the-air page.
Open Source Control → Pull Request on a branch with a PR: tap the failing-checks row (Checks screen; try ⋯ on a failure), the threads row (Comments; tap a thread for the Thread screen) and the approvals row (Reviewers sheet). Then use ⋯ → Edit title.
With a mergeable PR, tap the merge button: the sheet lists only the repo's allowed methods.
On a pushed branch with no PR, tap Create pull request: the title and description come from the commits. Try Write with AI and Base, then Create; you land on the PR tab.

Inline comments:
Review comments at @mobile/src/session/pr-actions-engine.ts:
- Line 244: **Prevent overlapping draft-state changes.**
The menu can issue a second `markDraft` or `markReadyForReview` request while
the first request is pending. The RPC path does not serialize these calls, and
the host limiter allows four concurrent GitHub operations. If the commands are
applied out of order, the pull request can end in a state different from the
user's last selection. Disable or serialize both actions until settlement.

Walkthrough
The mobile pull-request sidebar is replaced by a tab-based PR experience. The new flow includes overview gates, checks and comments screens, merge and reviewer sheets, editable PR text, and pull-request creation with base selection and generated fields. Source-control wiring now delegates PR state and creation handling to dedicated hooks. PR file schemas, mutations, shared hosted-review helpers, translations, and related tests are updated.
Merge Risk: Low · up to 50b08
Rapid repeated actions can start PR creation twice or leave a PR in a different draft state than the last selection. These are bounded interaction risks to address or explicitly accept; the previously reported mobile check failures are no longer present.

Select single-commit defaults only for one commit.
If two commits contain only one nonblank subject, this branch uses that subject as the title but takes the body from commits[0]. Mobile history permits an absent subject, so a PR draft can combine text from different commits. Require commits.length === 1 before using the single-commit defaults. Otherwise, retain the branch title and list the available subjects. (raw.githubusercontent.com)
setCopied(true) is never reversed. The menu closes after the press. Every later open shows "Copied" instead of "Copy link" until the host component unmounts.

Preserve the description when saving it.
If a draft starts with four spaces, trim() removes indentation that can define a Markdown code block. If a user removes only a trailing newline, the trimmed comparison returns null; save then reports success without sending the edit, and the editor closes. Compare the original strings and send draft unchanged. (raw.githubusercontent.com)
230-233: Minor · Functional Correctness · Quick win
Show the confirmed approval when review details are unavailable.
If the details fetch fails, the sidebar uses a placeholder without latestReviews. When pr.reviewDecision is APPROVED, this code then displays a green “No approvals yet” row. Use an approved title when the decision confirms approval but the reviewer count is unavailable. (raw.githubusercontent.com)
Fix the initial filter. It is fixed on the first render, before the comments load.
useState evaluates its initializer once. The screen mounts before data.details is available, and livePrDetails also strips placeholder details. In that case groups is empty and unresolved.length is 0, so filter starts as 'all'. The state then keeps that value after the comments load. The "open on Unresolved when threads exist" default does not apply in this case, and the user sees the full list.
Derive the default from the data and store only the user's explicit choice.
After a search for main succeeds, typing release leaves the main results selectable until the new search finishes. Selecting a stale row sets fields.base for PR creation. Clear results and failed when onChangeText updates the query, before starting the next search. (raw.githubusercontent.com)

Add a synchronous in-flight guard to create.
create checks creating, which is React state. setCreating(true) takes effect only on the next render. SheetPrimaryButton becomes disabled only after that render. Two quick taps in the same frame can therefore both pass the guard. Each run then calls runMobileHostedReviewCreateIntent. That run can stage, commit, push, and create the review, so the second run can produce a second commit or a duplicate create call.
The codebase already handles this case elsewhere. useMobileCommitFailureRecovery says: "Guard synchronously: launching state commits next render, leaving a gap for duplicate taps." Use the same pattern here with a ref.

Refresh the diff-review controller for committed Create PR results.
refetch({ includeDetails: true }) only reloads PR/sidebar data. When the create flow commits and then fails before creating the PR, this callback returns without reloading the screenState that owns gitStatus and headSha. Add a refresh callback backed by loadReviewData in useMobileDiffReviewController, pass it to MobilePRSidebar, and call it whenever committed is true. The controller's updated headSha will then trigger the sidebar controller's normal refresh.

The PR tab now leads with the PR's identity, one row per merge gate
(checks, unresolved threads, approvals, conflicts) that opens the screen or
sheet that resolves it, a changes card and a collapsed description. Close,
Unlink, Auto-merge, Edit title and Copy link move into the ⋯ menu.
Checks and Comments become pushed screens: failures open with their
annotation and Fix / Rerun / Open / Log on the failure, running checks
next, passed folded; comments filter by Unresolved / All / Hide bots with
Resolve and Reply on each thread and a comment box at the bottom.
Merge opens a sheet that lists only the methods the repo allows, starting
on its default. Reviewers move into a sheet with search to add and remove.
Every Create PR entry point opens one sheet: title and description seeded
from the branch's commits (shared seed rule in src/shared, GitHub's own
default), Write with AI, base picker and draft. It pushes first when
needed, works for all five providers and lands on the PR tab for GitHub.

On your phone, the Pull Request tab used to be one long list of everything. Now it answers "can I merge, and what's stopping me?" One row per blocker (checks, unresolved threads, approvals, conflicts) opens the screen or sheet that fixes it. Merging, picking reviewers and creating a PR each happen in a small sheet, and creating a PR no longer throws you out to the browser.

The bar's Merge opens the Merge sheet (new optionalonMergeonuseMobileSourceControlNextStep), its Create reaches the Create PR sheet throughcreatePrAction, and Checks and Comments are pages on the hub pager (SourceControlHubScreengains'checks' | 'comments'). The Checks fix prompt reusesbuildPrFixChecksPrompt.Why
The approved mock (1 Nov) makes the PR tab a decision surface: blockers first, each resolved where you tap it. Today's tab stacks every section with big Close/Unlink buttons at the top, has no way to pick a merge method, and creates PRs titled with the branch name before sending you to the browser.
The rules come from desktop rather than mobile copies:
resolveGitHubPRMergeState), merge methods, check verdicts, comment grouping and bot detection were already shared;src/sharedhere.The commit-based seed lives in shared code next to desktop's branch seed, so desktop can adopt it later without a second copy.
Linked Issue
No issue. This is the approved Source Control redesign ("Pull request", "Checks and comments" and "Sheets" in the 1 Nov mocks). Mark as draft (needs a new host method) is a separate host PR, and polling, thread code lines and "Ask to fix" follow in a stacked PR.
Visual Proof
Captured from the page bundle with scripted host replies (same demo data before and after), iPhone 15 size, dark.
Checks and Comments, before and after. On main they are sections of the one long PR tab (left two columns); here each is its own screen.
Other sheets:
Testing
Rendered every state above from the built page bundle with the capture rig (scripted host replies, no page errors), and compared it with the same rig on main.

Each fails on the code it replaces.Not tested on a device or simulator.

Review
Four review rounds (Codex and Claude) plus a check of the last round's fixes. Rejected or deferred:
git.history(whosemergeBaseis against the upstream, not the PR base), any merge in range falls back to desktop's branch-name seed.onOpenPrWeb/prNumberprops: left alone for sc-hub-changes, which owns that header.Checks/Comments redesign: four more rounds. Fixed: an iOS 15.1–16.3 parse failure from a regex lookbehind, menus running off-screen near the bottom, Android Back skipping the menu, errors hidden under the Thread screen,
aria-disabledleaking onto conversation rows, a tap through a closing menu opening a thread, Copy error feedback, Delete busy state, and a thread reappearing after a failed refresh. Follow-up: the covered Comments list stays keyboard-focusable behind the Thread screen, as the hub does under its own overlays.Agent skill upstream boundary
Notes
Mixed versions: every new read is optional. Older hosts without
fileshide the changes card; withoutgit.generatePullRequestFieldsthe sheet shows the host's error;git.historymessageis optional.Mobile outside the PR tab: the diff-review dock still mounts the same tab and gets its own ⋯ menu (Refresh even without a PR) and Back handling.
Desktop: behaviour is unchanged, apart from importing the moved shared modules. Desktop can adopt the commit seed later.
Folder workspaces and non-GitHub repos: the PR tab still shows "Hosted review panel unavailable"; Create works for all five providers.
Shipped shells: no native routes or native code changed; everything is in the over-the-air page.
Mobile verify must be green before merging.
Stack: on main (the 9.5 MiB fence from build(mobile): raise the page bundle's code fence from 9 to 9.5 MiB #37014 is merged); feat(mobile): PR tab refreshes itself, review threads show their code, bots get Ask agent to fix #37023 sits on top.
Diff screen comments: feat(mobile): GitHub review threads, viewed sync and line comments on the diff screen #37073's diff screen still renders threads with
PRCommentsSection/PRCommentCard, so those stay; moving it onto the new rows is a follow-up.What to try (paired phone or the page):
