At 03ec00d23fd7e50af8e82b7a349543f12a34593a, failed lazy-panel downloads are contained inside the right panel, leaving the running chat usable. Switching to another panel resets the boundary; retrying a rejected download offers a full app reload because React caches the rejected lazy import. The browser regression failed before the boundary and passes after it. Affected lint, format, knip, type checks, two test files and two compiler cases pass. The required vp run check:changed ad71d675207c1d0449ba751908087b9d363d0bd8 passed for this follow-up delta. The earlier main-integration verification below describes its recorded revision and scope.

chat/RightPanelSurfaceContent.tsx imports PullRequestDetailPanel and ThreadPullRequestsPanel statically, loading their dependencies with right-panel content even when a thread never opens a pull request. This change defers those imports until the corresponding panel renders. The older production-build measurements below predate upstream’s component extraction; no new bundle-size measurement was made for this head.
This uses the small-fix exemption for a focused performance and recovery fix to existing pull-request panels: defer their code until opened, retain their existing actions and defaults, and contain a failed download within the panel. Diff, Device and Files already use the same lazy-loading pattern. No prior maintainer scope approval is claimed. Macroscope approved the current 03ec00d head.
Both panels load with React.lazy behind Suspense, using the same named-export pattern as DevicePanel. The detail panel falls back to its existing PullRequestDetailGhost ("Loading pull request"), which is already in the eager bundle, so the first open over a slow remote link still shows a loading state. The list panel falls back to the existing PullRequestListGhost from the same module (follow-up commit after a CodeRabbit review; null left the panel blank while its chunk loaded).
At 9e86a21f32, integrated with upstream 70d60e03a7 on macOS, 2026-10-17:

Older terminal findings concern the excluded panel-host files, which are absent from this one-file diff. The current-head status says Review rate limited, so no fresh CodeRabbit review is claimed.Production build of apps/web on Linux (lxso3) for main 85272eeeae and for this change. Eager JS is every file reached by static imports from index.html, the _chat route and the thread route in the build manifest, with each file gzipped at level 9:

The two new lazy chunks are PullRequestDetailPanel (187 KiB raw, 57 KiB gzip) and ThreadPullRequestsPanel (15 KiB raw, 6 KiB gzip). The total drop is larger because modules that only these panels use moved out of the eager chunks too. A manifest check confirms neither panel chunk is still reachable eagerly.

Sol also reproduced the 112.2 KiB gzip figure from the build output. Round 2: no findings. A third review of the list-ghost follow-up (39197c743f): SHIP, no findings; at that head web typecheck, lint (0 errors), fmt and the same 157 tests pass on lxso3.No before/after screenshots: once loaded, the panels look and behave the same. The only new visible state is the existing loading ghost during a first open on a slow link.
Live check (GPT-6 Astra, T3 built-in preview browser, isolated dev server on lxso2 with copied state, this ChatView.tsx): both panels load through their lazy chunks and render. The linked pull requests list shows the thread's 8 linked PRs. The detail panel opens and renders its own error state, because GitHub had rate-limited the host at the time, so populated detail content was not seen.

Explanation
The description includes the Problem, Change, Scope and approval, and Verification sections. It explains the lazy-loading change and ghost fallbacks. It reports test, typecheck, lint, format, and browser-regression results at a specific revision. It also identifies unverified browser parse/evaluate timing, populated live PR detail content, and integrated client passes at the current head. The description is incomplete because it lacks explicit maintainer approval, mixes verification results from different revisions, and omits before/after UI evidence required by the template. It also needs the required commit title style and agent attribution confirmation.
Resolution
Link the triaged bug issue or discussion that contains explicit maintainer approval. If the small-fix exemption applies, explain why this is a very small, focused fix for an obvious bug. Report verification results for the current head only, ad71d675207c1d0449ba751908087b9d363d0bd8 or later. Move earlier results to a clearly labeled history section. Add before/after screenshots or a short recording that shows both panels opening while their chunks load. Include populated detail content if available. Upload the media to GitHub and link or embed it. Keep the Problem and Change sections in the template structure. Add the template commit title style if the title does not already follow it. Confirm that the description ends with the required agent attribution.

A newly created right-panel terminal is opened with the stale launchContext from the currently running drawer script, so it can start in that script's non-default checkout or directory instead of its own summary/default location. Because TerminalViewport may attach before openOrAttachForStream creates the missing session, this stale context wins on the server.

This is unchanged from main: main's ChatView applies the one terminal launch context to every terminal id in the same loop, and this stack only moved that code into TerminalSidePanel. Giving each terminal its own launch context changes how New and Split open terminals, so that change belongs in its own PR, not in this move.

Not changing this in the stack. This guard is main's own code: serverTerminalIdsStrictSubsetOfClient and the same early return are in apps/web/src/components/ChatView.tsx on current main (around lines 948 and 1119), and this stack only moves that block into the terminal panel. Reconciling a server list that drops a persisted terminal needs a signal for which opens are still pending, which is a behaviour change for its own PR rather than part of this refactor.

✅ Confirmed as addressed by @saphid
Agreed. Fixed in 39197c743f: the linked pull requests panel now falls back to the existing PullRequestListGhost (same module as the detail ghost, already loaded with ChatView) instead of null, so a slow first open shows the list skeleton rather than an empty panel.
@saphid Thanks for the fix. The supplied code uses PullRequestListGhost as the ThreadPullRequestsPanel loading fallback, which addresses this finding.

Written by gpt-6.1-sol on behalf of Maria
this pr does not meet verification. the diff adds lazy loading and Suspense fallbacks for both pull request panels. the description supplies older screenshots of a loaded list and an error state, explicitly provides no before screenshots, and leaves populated detail content and browser timing unverified. those artifacts do not show the changed first-open transition.
please add matching before/after client evidence and a short recording of both panels opening while their chunks load, including populated detail content. report the focused checks and observed result, then request reconsideration.

Defer the page-level detail import.
autoCodeSplitting keeps this route out of the initial startup bundle, but it does not defer imports inside the route component chunk. When /pull-requests loads, PullRequestsPage statically loads PullRequestDetailPanel before a page-level detail surface opens. This leaves the standalone right-panel path outside the new lazy boundary.
Use the same named-export lazy import in PullRequestsPage and wrap its existing detail render in Suspense with PullRequestDetailGhost.

When either lazy import rejects,
Suspensedoes not handle the error. React throws it to the nearest Error Boundary. Neither right-panel path has a local boundary, so TanStack Router uses the inherited root error view and can replace the active route, including the running chat. Itsrouter.invalidate()action re-renders the same module-scoped lazy component. React caches the rejected import promise, so that action cannot retry the chunk. Only a full reload currently retries it.A boundary around the shared
RightPanelTabschildren can cover both the chat detail/list branches and thePullRequestsPagedetail branch. Its recovery must recreate the lazy component or explicitly reload the app; resetting only the boundary is not sufficient.External image Prompt for AI Agents

merged github/main (4bfb896d00) into the head as a5d65df405 to clear a conflict in PullRequestsPage.tsx. main had changed the detail panel's reference and onActed props; the resolution keeps main's block unchanged and only wraps it in this pr's Suspense with PullRequestDetailGhost. no other changes.
