perf(pr): PR panel paints from saved data and reads ahead on intent - #32911
Opening a PR still showed loading states for data that was saved or soon needed. This PR paints from saved data and starts reads before the click. It builds on #32842 (and #32774). This branch carries both.
Problem
The stack was not saved. A reopened stacked PR showed "Checking stack membership…" with Merge off.
PR links in chat and a thread's PR rows opened the panel cold. The Code tab read its diff only after the click.
The actions menu spun on every background read.
The checks popover used a different cache key than the panel, so it showed "Loading checks…" for a loaded PR.
Fix
Saved stack, merge still safe. The stack is saved on the device and paints at once. Merge still waits for a settled host answer in this session (pullRequestStackAtom.answered). The same rule applies on mobile.
Reads on intent. An open PR link card (also bare #123), a thread PR row under the pointer, and the Code tab under the pointer start the reads the click needs. Each read uses the same key as the click, so it is never wasted.
The menu spins only for a refresh the user asked for.
The checks popover uses the panel's key.
Removed the "Waiting for host state" and "Loading breakdown" labels.
First visit paints. With no saved list, the app reads the list the PRs page opens on once, in the background. It does this on web and mobile, and again after a reconnect if the device was offline. A saved list costs no extra read.
The host's own title wins. If a read during a title or description save shows different text, for example a trimmed title, the panel reads that PR again. The typed text no longer stays on screen. Other saves make no extra read.
Host calls
Only the first-visit list read starts without intent. Passing over a row reads nothing, because the pointer must stop for 150 ms. A stopped pointer costs the same reads the click makes a moment later. Diffs load only on Code tab intent, never on row hover. The first-visit list read happens only when the device has no saved list for that view.
Not covered
Mobile has no hover, so it gets no early read.
Verified
New tests fail on the base and pass now. They cover client-runtime stack state, the stack snapshot, the link preview, the thread PR panel, the detail panel and the first-visit list read.

A reader opened, or still loading, during a title save also ends on the host's own title.
Restacked linearly on the updated #32842 and main (the earlier merge commit is gone). Read-ahead tests now check only the key the click reads; activity mocks are removed. Proof: vp run check:changed passes on this head (321 tests, 37-package typecheck including mobile).
Review round (merged reworked #32842 and current main)
PullRequestsPage.tsx: kept main's baselineTargetsFor(queries), so refresh still reads preferredEnvironmentQueries.
PullRequestListWarmup.tsx: passes hostAvailability to usePullRequestScope (fixes TS2554).
A host-rewritten title survives a failed re-read. Say the host's text changed during a title or description save, for example to Draft: Edited. settleEdit re-reads without writing the typed text first, and it reports the rewrite. The shared summary and retained list rows then skip the typed text. Before, if the re-read failed, the cache kept Edited. The "host rewrites the title but re-read fails" case covers it and failed before the fix.
The list warm-up skips environments with no project that can have pull requests.
Saved stack data still cannot enable Merge: both stack hooks need a settled read from this session.

Painting from saved data, at c089e6dc17:

Close then reopen while the close is still in flight: Reopen and Delete branch stay disabled until the close lands, as on main, so the close settles and Reopen works right after.
Macroscope's review found this PR approvable — PR views paint from saved data and read ahead on navigation intent, reducing loading delays. Reads retain existing scope, and restored stack data must receive a host answer before being treated as fresh for merging.

Walkthrough
The changes add optimistic pull-request updates, list warm-up, and stack answer tracking. Web link previews and thread rows can prefetch pull-request data. Panel interactions and unavailable-data labels change. Pull-request details now carry optional merge-queue metadata.
Pending action, title, body, and label edits appear in matching readers while writes are in progress. Settled edits and summary selection account for loaded data and stored snapshots. Tests cover pending, accepted, refused, and overlapping operations.
List targets and warm-up wiring apps/mobile/src/features/pull-requests/*, apps/mobile/src/App.tsx, apps/web/src/components/pullRequest/usePullRequestListView.ts, apps/web/src/components/pullRequest/PullRequestsPage.tsx, apps/web/src/components/pullRequest/PullRequestListWarmup.tsx, apps/web/src/components/AppSidebarLayout.tsx, packages/client-runtime/src/state/pullRequests.ts, packages/client-runtime/src/state/pullRequests.test.ts
Web and mobile list views build request targets and mount list warm-up. The runtime loads persisted list data when available; otherwise, it mounts and reads the list.
Stack freshness requires a host answer. Saved stack data can remain visible while a host read is pending. The notice and tests reflect the updated freshness conditions.
Code-tab intent triggers a delayed diff read, and background detail reads do not activate the refresh indicator. Pull-request rows use fallback labels or titles when snapshots are unavailable. Label selections can be submitted while another change is pending.

The description is mostly complete and matches the template. It has a clear Problem and a Fix, plus Host calls, Not covered, and Verified notes. It also gives verification details: check:changed passes, mobile typecheck passes, and the new tests cover the changed areas. Its heading structure is different from the template, and the Scope section is missing. The author does not say whether this is a bug fix or a feature, or link an issue. The PR is also framed as a perf change, not a bug fix. The description also contains stacked-PR notes and 'Fixes pushed on top' text that do not fit the template. Those parts could be cleaned up.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Wait for the read itself, not for one scheduler tick.
The warm-up atom runs again only after the connection change goes through environmentConnectionAtoms and then environmentSessionGenerationAtom. One Effect.yieldNow does not guarantee that this has happened. If it has not, AtomRegistry.getResult(registry, warm, …) returns the warm-up's earlier offline Success at once. reads then stays 0 and the alreadySaved: false case fails intermittently.
The testing rules say: "No yieldNow or sleep polling loops. Await the Deferred, take from the Queue, or drain the worker." Complete a Deferred in the pullRequestsList handler and await it in the !alreadySaved case. For the saved case, assert on a milestone such as the session generation value.
As per path instructions: "Do not use sleeps or polling to wait for work: await a milestone or drain the effect worker as appropriate."

merged main with a merge commit (no rebase). one conflict, in the generated pullRequestReads.graphql.ts. regenerated it from the merged .graphql, which keeps this pr's isMergeQueueEnabled and main's label description.

vp run check:changed passed on a testbox: format, lint, knip, graphql, typecheck of 37 packages, 13 test files, react compiler. RightPanelTabs.browser.test.tsx also passes.
unverified: no new browser run this round. the merge changed no pr logic.
Earlier takeover update (2026-11-11)
head is now f372d0a662.
merged main with a merge commit (no rebase). two conflicts:
PullRequestDetailPanel.tsx: kept this pr's refreshing = isInvalidating (background reads repaint without motion) and main's refetchFromHost, which reports whether invalidation succeeded for link reveals.
PullRequestLinkPreview.tsx: imports only. kept main's review-outcome and link-subject imports and this pr's pullRequestPanelReference.
vp run check:changed passed on a testbox: format, lint, knip, graphql, typecheck of 37 packages, 13 test files (326 tests, including the link preview and detail panel browser tests), react compiler.
Refresh now keeps its spinner until the detail read settles, not just the host invalidation. Background reads still repaint without motion. This addresses the new CodeRabbit finding.
check:changed passed again after that fix. unverified: the spinner timing was not exercised in a real browser.

merged main with a merge commit (no rebase). one conflict in AppSidebarLayout.tsx: kept main's showSidebar prop on SidebarControl and this pr's PullRequestListWarmup.
Code tab read-ahead now waits for the pointer to rest 150 ms and cancels on pointer leave, matching list rows. keyboard focus still reads immediately. the Code tab test now checks the delay.

removed ThreadPullRequestsPanel.browser.test.tsx: it repeated the intent-prefetch hook's key check at one call site.
the list warm-up test in client-runtime now awaits the reconnect read on a Deferred instead of one Effect.yieldNow.
vp run check:changed passed on a testbox (format, lint, knip, graphql, typecheck of 37 packages, 13 test files, react compiler). the three changed pull request browser test files pass.
declined bot findings:
tie-breaking unstamped list reads in newestPullRequestSummary: only older servers send no observedAt, the stale mergeability lasts until the next detail read, and keeping the shown summary on a tie protects in-flight edits by design.
isMergeQueueEnabled @include(if: $required) on Enterprise: this follows main's existing isRequired @include(if: $required) guard in the same query, and main's merge and action-state queries already ask isMergeQueueEnabled with no guard. a separate Enterprise document would grow this pr.
removing the hover tests in PullRequestLinkPreview, usePullRequestIntentPrefetch and the Code tab: they check the read-ahead key matches the key the click opens with. a mismatch means a second host read, and the link preview case covers the /issues/ to pull request mapping.
unverified: the new Code tab hover delay was not exercised in a real browser this round, only in the browser test.
Verified in a real dev environment
verified the web read-ahead behavior at 44f9523de1b003b96085dd7808751f3127d7e43f, against github/main at d1909d68f8. separate worktrees, isolated app state, one background dev server at a time, repo Playwright with /usr/bin/google-chrome. projects, threads and real Codex gpt-6.1-sol turns were created through the app. no mocks or seeded data.
main: chat-card hover fetched only the preview. detail and activity waited for the click. the pr head fetched both before clicking and reused them when opening the panel.
main: no diff request during code-tab hover; the real diff request started 130 ms after clicking. the pr head started it 89 ms after hover, 1,001 ms before clicking. these are observed client request timings, not a claim that loading always finishes before a click.
the first-visit list read started while still in chat. summary, timeline, the real 40-file code view, panel reopening, linking this pr to the thread, and cancelling a title edit worked.
a fresh linked-pr row also sent detail and activity reads on hover before clicking.
repeated the chat path with a GitHub-backed project. its real server detail response included provider=github and mergeQueue=false. after loading detail, the pr-list checks popover displayed the real checks without a new detail request or a cold loading state.
blacksmith: vp run check:changed 8e6a7323050ea8d2891f745f7e624e84f9fd8d9a passed, including 321 tests across 14 files, typechecks, lint, formatting, dependency checks, graphql and compiler checks. the separate focused run passed 179 tests. host checks report 33 successful, 0 failing, 0 pending.
short runtime transcript:
main hover chat -> preview
pr hover chat -> preview + detail + activity
pr click chat -> cached detail/activity reused
main code hover -> no diff request; click -> POST /api/pull-requests/diff
pr code hover -> POST /api/pull-requests/diff before click
GitHub checks -> existing detail reused, checks visible
same pr, same panel crop on main and the pr head:

Clear the pending pointer timer when the tab bar unmounts.
pointerIntent starts a 150 ms timer on pointer enter. Only pointer leave clears it. If the bar unmounts during the 150 ms window, the timer still fires. It then calls onTabIntent, which calls setCodeIntentKey on the parent panel. The effect is small. The stale callback can still start a diff read for a pull request the user no longer views.
Add an effect cleanup that clears the timer on unmount.

Module-level mutable state conflicts with the browser test rules.
The state object is mutated at Lines 110 and 111 (state.restoredPreview = null; state.reads = [];). The rules say: "Shared mock state that vi.mock factories read is reset by a setup() call at the top of the test." This test resets the state inline, and the existing tests do the same. A setup() helper would meet the rule and stop reads from leaking between tests.

For non-github.com hosts, the query omits isMergeQueueEnabled. The fixture always supplies false, so this test cannot catch a regression that converts an unknown value to false. The client would then optimistically show a merge as completed.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Reuse pullRequestLinkPanelTarget or note why this path differs.
The preview resolves the panel reference with its own parsing and uses target.input.projectId directly. The click path in openPullRequestLink.ts uses pullRequestLinkPanelTarget, which picks a project by environment and repository. If these two paths pick different projects, the prefetch cache key will not match the key the click uses. The read-ahead is then wasted.
In most cases target.input.projectId is the right project, because the preview target is already resolved by the caller. Add a short comment that says so, or reuse the shared helper so both paths use the same key.

Pending timer is not cancelled on unmount.
The setTimeout at Line 56 has no cleanup on unmount. If the component unmounts within 150 ms of an intent, setTarget runs on an unmounted component. React ignores this, so there is no visible failure. Cancel the timer in an effect cleanup so the hook follows the timer-cleanup convention.
Based on learnings: flag component timers that lack cleanup on unmount.

Intent cleanup is incomplete when focus moves between children of the row.
onBlur fires when focus moves between children inside the row. For example, focus can move from the link to the menu trigger. If the pointer is not over the row, onIntent(null) runs, and the next onFocus re-arms the 150 ms timer. This causes a brief clear and re-arm cycle. It is harmless but wasteful.
Check event.relatedTarget in onBlur. Skip the clear when event.currentTarget.contains(event.relatedTarget).

onBlur={(event) => {
- if (!event.currentTarget.matches(":hover")) onIntent(null);+ if (+ !event.currentTarget.matches(":hover") &&+ !event.currentTarget.contains(event.relatedTarget as Node | null)+ ) {+ onIntent(null);+ }

for the host, because a merge queue can accept without merging.

The title editor closes at once and no longer re-reads detail, activity,
and stack after a save. The label picker stays usable while a change is
in flight; changes queue on the host in order.

An open-only list dropped a pull request when a queued close was followed
by a queued reopen, because each pending edit filtered the row on its own.
Readers now get all pending edits for their pull request at once, and the
list checks membership against the row's final state.

When the detail read had no value yet, the panel fell back to its stored
snapshot. Against an older server that sends no observedAt, the snapshot
tied the shared summary, won the tie, and hid a pending or accepted title
until a detail read succeeded. A shared summary now wins a tie against
the stored snapshot. A loaded detail keeps winning ties, since it already
carries the edits.

A label-candidate read that had not answered yet was skipped when an
accepted change settled, so its reply, sent before the change, could show
the label as not applied once the overlay was gone.

…it queues
GitHub (gated for older Enterprise) and Forgejo report whether a merge joins
a queue, so the client shows merged, or auto-merge on, before the host
replies. A refusal puts it back. The checks read also shows writes and takes
action replies, since the panel can take its state from it.

Resting on a PR row now reads its activity too, so the timeline paints on
click. The server caches it, so it asks the host nothing new.

The merge left alone where the host cannot say whether it queues is now a
row of the table that covers merges that land or queue, rather than its own
test.

[Opus 5.5][Claude Code] on behalf of shivam.
Fixed at c089e6d: main's baselineTargetsFor is kept; PullRequestListWarmup passes hostAvailability, an empty Map like the page's first read; a title the host rewrote is re-read without writing the edit first, with a failed re-read case in the test table. Rebuilt on #32842. Checks green.
…ashing the old title
The list warm-up read through the page's wrapped reader. Those wrappers
stay cached for five minutes, so a failed warm-up read was what the PRs
page showed on its first visit, with no read again. It now reads the bare
query, which re-reads a failed answer when the page mounts it.
A reader that loaded during a title save, from a read answered before the
host committed, was compared with the typed text and taken for a host
rewrite. The save then skipped shared summaries and the old title showed
until a re-read. Such a reader now compares with what other readers held
when the save was sent.

Hard-tested this PR (web and iOS against real GitHub), then pushed e80cad7e20. It merges the updated #32842 (which is now up to date with main after #32774 landed) and fixes the two bugs the testing found.
1. A failed first-visit warm-up left the PRs tab stuck (mobile). If the warm-up's list read failed (for example while GitHub calls were paused for the rate limit), opening the PRs tab showed "Couldn't load pull requests" without reading again, for up to 5 minutes. Only a relaunch recovered it. Cause: the warm-up read through the page's wrapped reader, and those wrappers stay cached for 5 minutes. That kept the query's revalidate-on-mount layer alive, so the page's first mount was served the failure. The warm-up now reads the bare query, which drops that layer when it lets go, so the page re-reads a failed answer on mount. A successful warm-up still paints the page with no second read. New test "reads the list again when the page opens after the warm-up's read failed" times out on the previous head and passes now; both existing warm-up tests still pass.
2. A long title save flashed the old title for about 2.6 s (web). A reader that loaded during the save, from a read answered before GitHub committed, held the old title. It was compared with the typed text, taken for a host rewrite, and the save then skipped shared summaries, so the old title showed until a re-read. Long titles only made this likelier because they take longer to save. Such a reader is now compared with what the other readers held when the save went out. A real rewrite (Draft: …) is still re-read, and the five existing rewrite cases pass unchanged. New test "keeps an accepted title when a reader opened during the save reads the text from before it" fails on the previous head and passes now. In the app, 2 of 2 long-title saves no longer flicker, and GitHub matched.
vp run check:changed passes at this head.
Not re-run on a device: the mobile fix is in shared client-runtime code and covered by the unit test above. Earlier test findings that are unchanged and inherited from main: the server's PR read cache can enable Merge for a stack that changed on GitHub. Cost to know about: each opened link card now costs 2 reads even when it isn't clicked.
…one that saw it
Each reader decided on its own whether the host rewrote a saved title. A
reader that saw no change took the typed text, so a list page the server
does not refresh kept "Edited" while the host had "Draft: Edited". The
save now checks every reader first, and when any saw a rewrite, all of
them read again instead of taking the typed text.

Opening a PR still showed loading states for data that was saved or soon needed. This PR paints from saved data and starts reads before the click. It builds on #32842 (and #32774). This branch carries both.

pullRequestStackAtom.answered). The same rule applies on mobile.#123), a thread PR row under the pointer, and the Code tab under the pointer start the reads the click needs. Each read uses the same key as the click, so it is never wasted.Host calls
Only the first-visit list read starts without intent. Passing over a row reads nothing, because the pointer must stop for 150 ms. A stopped pointer costs the same reads the click makes a moment later. Diffs load only on Code tab intent, never on row hover. The first-visit list read happens only when the device has no saved list for that view.
