fix(prs): queue fast actions and close batches by dragging

[maria-rcks]

Rapid close/merge clicks restarted other merges' preflight reads and duplicated refresh notifications. Fast mode now queues fresh merge preparation with each action, recovers canceled cache lookups, preserves cached rows on repository-read failures, and keeps confirmed closed/merged rows out of the open list.

Hold Shift, press Close, and drag across rows in the same group to close a batch, matching the settled sweep. Release queues eligible rows in order through the existing environment lanes. Failed closes do not stop the rest, and one summary reports the result. Escape cancels before or after the drag threshold. Sweep previews and queued closes keep the existing action buttons and labels visible, with the same disabled button spinners as ordinary clicks.

Verification on cbc87b5: all GitHub checks pass, the branch is mergeable, and no review threads remain open. Blacksmith web typecheck, targeted component lint (zero warnings/errors), and 30 existing pointer/checks tests pass. Both independent source reviewers approve this head. Earlier checks for the unchanged fast-action logic passed 181 service, 131 list, 58 client-runtime, and 144 sidebar logic tests, including a batch whose middle close fails. A duplicate import in the base that blocked server startup/typechecking was removed.

Current-head native browser verification with real GitHub fixtures: sweeping shows the normal disabled Close/Merge button spinners, with labels and sizes retained. Escape restores the icons without sending an action. Reverse release submitted one close each for #6, #5, and #4 in displayed order. Current-head provider completion remains unverified: the shared guarded GitHub read budget is exhausted; the actual action reply records getViewerPermissions failing with gh exit 75. The app reports the refusal and keeps failed rows.

Previously verified through the same client and provider path: the six-action burst completed three closes and three merges. The sweep submitted #4, #6, and #5 exactly once in order and displayed one "Closed 3 pull requests" summary. Active and below-threshold Escape sent no action RPCs and suppressed the release click. Reverse selection at 768x900 in light theme preserved all three rows on cancellation, and ordinary row navigation loaded the actual PR detail. Single close/reopen passed before the spinner change. The web list is shared by desktop; mobile has no equivalent PR list. A real two-group boundary sweep remains unverified; both reviewers verified its displayed-order and same-group guards in source.

The six-action burst used the same isolated environment and equivalent one-line fixtures; candidate merges use new PRs because merged PRs cannot reopen. Outgoing RPC counts, before versus after:

rpc	baseline ad5178a	candidate 247dc9c	change
list	36	18	-18
detail	20	3	-17
stack	11	3	-8
list stats	14	6	-8

The short preview/cancel recording below removes the idle middle: source ranges 0–4 seconds and 49–53 seconds. It shows the real buttons changing to spinners and cancellation keeping the rows; it does not claim a successful current-head provider close.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The PR adds a new drag-to-close workflow that can issue multiple remote pull-request close operations and changes the shared action-queue and merge-preparation pipeline. Its external side effects and cross-cutting runtime behavior warrant human review despite targeted tests and deliberate user activation.

Written by gpt-6.1-sol on behalf of Maria

ci is blocked by the current upstream base: scripts/setup-worktree.ts:37 uses console.warn, which fails Effect's globalConsole typecheck rule (TS377064). that line is absent from this branch's base commit and unchanged by this pr. focused checks and the real browser/github path passed. both independent reviewers approved the current head; the unrelated setup change needs an upstream fix before ci can become green.

📝 Walkthrough

Walkthrough

The changes update interruption handling for pull request reads, state filtering and empty-baseline handling in pull request lists, batch closing through pointer sweeps, and merge action preparation within serialized environment commands.

Changes

Server pull request reads

Layer / File(s)	Summary
Retry interrupted list reads apps/server/src/pullRequest/PullRequestService.ts, apps/server/src/pullRequest/PullRequestService.test.ts, apps/server/src/device/LocalDeviceHost.ts	List and stats reads retry when a failure contains only interrupts. Tests cover a replacement read during cancellation. A duplicate import is removed.

Pull request list and close sweep

Layer / File(s)	Summary
Filter and group pull request entries apps/web/src/components/pullRequest/pullRequestList.logic.ts, apps/web/src/components/pullRequest/pullRequestList.logic.test.ts, apps/web/src/routes/_chat.pull-requests.tsx	The list filters rows by override state or current state. When the baseline is settled and empty, the route records empty priority partitions and groups current entries directly.
Run eligible close actions apps/web/src/components/pullRequest/usePullRequestActions.ts, apps/web/src/components/pullRequest/PullRequestRow.tsx, apps/web/src/components/pullRequest/PullRequestSpeedActions.tsx, apps/web/src/routes/_chat.pull-requests.tsx	The close hook runs eligible GitHub pull request closes concurrently, tracks pending entries, and reports results. Rows and action controls show closing and sweeping states.
Select rows with a pointer sweep apps/web/src/routes/_chat.pull-requests.tsx, apps/web/src/components/Sidebar.pointer.ts, apps/web/src/components/Sidebar.pointer.test.ts, docs/user/source-control.md	The route selects eligible rows in the same group and submits them as a batch on release. Escape and list changes cancel the sweep. The documentation describes the interaction.

Merge action preparation

Layer / File(s)	Summary
Resolve merge methods during action execution packages/client-runtime/src/state/pullRequests.ts, packages/client-runtime/src/state/pullRequests.test.ts, apps/web/src/components/pullRequest/usePullRequestActions.ts, apps/web/src/components/pullRequest/PullRequestSpeedActions.tsx	The action runner passes a merge-method resolver to the runtime. The runtime fetches fresh detail, checks merge eligibility and stack status, resolves the method, then dispatches the action. Tests cover action ordering and rejection cases.

Merge Risk: ⚪ Minimal · up to cbc87

The batch-close gesture remains gated by Shift, and the merge eligibility tests detect missing guards. No actionable current-head regression remains; the PR is ready for normal merge checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to cbc87

Closing several pull requests at once increases the scope of a user action, but the reviewed paths preserve account permissions and repository identity. No new permission bypass was identified. Recovery after an interrupted remote action remains only partially verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — A sweep expands one user gesture from a single pull request to eligible rows within one displayed involvement group. That group is not a repository or environment isolation boundary, so the operation can affect multiple repositories or environments represented there. Each write nevertheless retains its own target reference and encounters the existing routing and provider authorization controls.

Trust Boundaries and Controls

• observed — Existing delegated GitHub writes require enabled source and destination environments with read-write routing permission. Alternate execution checks host and account identity, and the server verifies the expected account against the credential used for the operation. The PR continues through this unchanged routing path.

Resilience and Maintainability Implications

• observed — Before submission, Escape, pointer cancellation, window loss, and route/filter cleanup cancel the gesture. Cancellation also suppresses the release click below the drag threshold, preventing it from falling through to an unintended individual close. Ordinary non-cancelled clicks retain their existing action path.
• observed — The new retries apply to cached reads, not writes. Existing write routing only tries another candidate for failures classified as occurring before dispatch; ambiguous write failures are not automatically replayed. This limits duplicate mutation risk but does not establish exactly-once completion or transactional rollback for a submitted batch.

🟡 Minor · Refresh the environment list and stats after a speed action… · _chat.pull-requests.tsx:966-971

apps/web/src/routes/_chat.pull-requests.tsx:966-971
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Refresh the environment list and stats after a speed action succeeds.

PullRequestSpeedActions calls onActed after the action succeeds. The route now applies only a row override. runAction refreshes the separate preview query, while the list and list-stats queries refresh only from the environment refresh signal. The displayed pull-request row and its line-count stats can therefore remain stale until a later live or turn refresh.

Suggested fix

   speedActionRef.current = ({ entry, action }) => {
     // Some hosts accept a merge before it completes. Let the next host read declare it merged.
     if (action !== "merge") overrideEntry(entry, action);
+    refreshListAndStats(undefined, entry.environmentId);
   };

Make only the method case reject the resolver.

The closed, draft, permission, and stack cases do not independently test their eligibility guards. If a guard is removed, the resolver still throws, so the merge still fails and only "close" is recorded. Return "squash" for the other cases so removing an eligibility guard allows the merge action and fails the test.

Suggested fix

             resolveMergeMethod: () => {
-              throw new Error("No merge method is available.");
+              if (reason === "method") throw new Error("No merge method is available.");
+              return "squash";

Note

Written by gpt-6.1-sol on behalf of Maria

the refresh signal is emitted by every successful action. PullRequestService.runActionAndInvalidate sets pullRequestRefreshes after bumping listingsEpoch (PullRequestService.ts:3240-3244); the client list and list-stats atoms subscribe to that signal (client-runtime/state/pullRequests.ts:228-243). the real first-page browser/GitHub burst already confirmed immediate list updates. adding another explicit refresh would duplicate those reads and restore the cancellation churn. the same finding was addressed here: #15851 (comment).

the eligibility-test finding is fixed in f41b04d. the resolver throws only for method and returns squash for the other cases. on blacksmith, removing each of the closed, draft, permission, and stack guards independently failed its behavioral assertion. the source was restored and all 57 tests passed; client-runtime typecheck and scoped lint also passed. both independent reviewers approved this head.
