In `@apps/server/src/pullRequest/GitHubPullRequestProvider.ts`:
- Line 74: Update the stack rebase permission logic in GitHubPullRequestProvider
so runGitHubStackAction preflights viewerCanUpdateBranch for every open stack
layer before applying any updates, rather than relying only on canWrite or the
selected pull request’s didAuthor status. Reject mixed-author or otherwise
non-updatable stacks before mutation, and add a test covering a stack where the
user authored only the top layer.
In `@apps/server/src/pullRequest/githubStackActions.ts`:
- Around line 146-149: Update the polling loop around the stack merge status
check to allow several minutes for completion instead of stopping after roughly
two minutes, and replace the fixed one-second sleep with an increasing backoff
between polls. Preserve the existing UUID validation and pending-status behavior
while reducing repeated gh invocations.
- Around line 88-95: Update runGitHubStackAction to accept expected head SHAs
for every affected stack layer, then validate each layer’s current headSha
against its corresponding expected SHA before invoking any gh pr update-branch
--rebase mutation. Preserve the existing stack and top-layer identity checks,
and fail with "changed" on any mismatch.
In `@apps/web/src/components/pullRequest/PullRequestRow.tsx`:
- Around line 126-127: Add an accessible visually hidden label identifying the
stack fraction as a stack layer within the row button, and mark the decorative
visual fraction as aria-hidden. Update the stack badge markup around
entry.stack.position and entry.stack.size without changing its displayed
appearance.
In `@apps/web/src/components/pullRequest/PullRequestStackMenu.tsx`:
- Line 83: Update the failure branch in PullRequestStackMenu to import and use
readableFailure for squashAtomCommandFailure(result), passing the
stack-operation hint so unknown failures receive shared message cleanup instead
of String conversion.

Stacked PRs need a way to move between layers and operate on the whole stack from the review page. This adds a position badge to PR list rows and a stack menu in PR details with layer titles, links and state.
Merge stack uses GitHub's asynchronous stack merge API after validating every layer’s expected revision and the selected strategy, respecting branch rules and merge queues. Rebase stack uses GitHub GraphQL mutations with each reviewed head SHA, updates unmerged remote branches bottom to top without changing the local checkout, and reports partial progress if a layer fails. Both actions show their scope before confirmation. Stack rebase currently requires repository write access.
The new fields are optional and mutations require the environment descriptor capability. Older environments retain their existing single-PR actions; older clients can keep using newer environments. Native stack operations stay in the GitHub provider boundary. Web and desktop share this UI; mobile keeps its existing host handoff.
Verification: 246 focused server tests pass, including 12 stack-action tests. Focused web merge-control tests, server/web typechecks, and targeted lint passed. Browser checks covered stack navigation and cancelled merge/rebase confirmations. Fourteen live scenarios ran through the production stack-action helper on disposable GitHub stacks: clean updates, no-op repeats, new commits on lower/middle layers, amended lower/middle commits, conflicts at every layer, retry after resolution, stale revisions, pushes during preflight/mutation, and a closed layer. The concurrent-push test found and verified the revision-guard fix. Amended parent commits can still require manual conflict resolution through GitHub’s per-PR API. All six fixture PRs were closed without merging and their branches were deleted: #10884, #10885, #10886, #10889, #10890, #10891. This layer does not create or reorder stacks.
Depends on #10870.
Link and unlink actions live in the PR More menu. Linked-thread counts appear only on the Pull Requests page; thread-context headers omit them. Browser verification covered both contexts and opening the thread picker after the menu closes. Web typecheck passed.
