statusReorderVersionRefonly controls local rollback. It does not orderupdateStatusOrdercalls. A second drag can sendPUT /statuses/orderwhile the first request is pending.

Reviewed 4afb8f4. Adding project scope fixes the original API problem, and queuing requests avoids out-of-order persistence. Two failure paths still corrupt the displayed group order. I reproduced the consecutive-failure case by executing the status reorder branch extracted from this exact commit with failed API responses. Please cover queued failures and project switching before merging.

[P2] Roll back to committed order rather than the preceding optimistic order. With saved ABC, drag to BAC, then to BCA while the first request is pending. If both queued requests fail, the first failure is skipped as stale, and this inverse move restores BAC even though the server is still ABC. The catch branch has the same issue. Reproduced by executing this commit's status branch: committed=ABC, UI after rollback=BAC. Reload authoritative groups on the latest failure, or maintain an acknowledged-order snapshot.

[P2] Invalidate reorder callbacks when changing projects. Resetting the queue does not cancel the pending promise, and statusReorderVersionRef is unchanged. If project A has a pending reorder, switch to B, and A fails before any reorder in B, its version still matches and its rollback dispatches A's groups into the shared reducer now displaying B. Advance/invalidate the version on project changes and guard callbacks by project identity; verify that delayed failures cannot replace the new project's groups.
Avoid inverse-splice rollbacks that can leave columns in the wrong order when multiple optimistic reorders are queued. On the latest failed request, reload the project's groups from the server instead. Invalidate pending reorder callbacks when the project changes, and verify project identity before callbacks trigger recovery. This prevents a delayed failure from replacing the groups displayed for the newly selected project.

Update the project ref after commit.
React can discard a render after this line sets currentProjectIdRef.current. If a render for project B is discarded while project A remains displayed, a failed reorder for A fails the recovery guard. The optimistic order can remain visible after the request fails. Move the ref update to a commit-phase effect.

Move ref writes into an event handler or effect. Render must stay pure because React can replay or discard it. The predictable null-guarded lazy initialization pattern remains supported.

Prevent stale recovery fetches from replacing current board state.
The project and reorder checks run only before fetchEnhancedKanbanGroups is dispatched. Its fulfilled reducer later assigns the response to state.taskGroups without checking the current project, request, or reorder generation. A recovery fetch can therefore finish after a project switch or later optimistic reorder and replace the current board state. Apply a project and board-generation check when the result is reduced. Apply the equivalent check to the rejected handler.

Re-reviewed e7b4d3d. Reloading authoritative groups addresses consecutive reorder failures, and the project/version checks prevent dispatching recovery after the project has already changed. One asynchronous project-switch window remains: the recovery fetch itself can complete after switching. I executed the actual fetch fulfillment reducer with B completing before the earlier A recovery; it finishes with loadedProjectId=project-A and A groups. Static/source execution validation, without a live backend.

[P2] Guard the recovery fetch result as well as its dispatch. If a reorder fails while project A is active, this starts an A fetch. Switch to B while that fetch is pending, let B load, then let A finish. fetchEnhancedKanbanGroups.fulfilled unconditionally replaces shared taskGroups and loadedProjectId with its payload/arg, so A overwrites the board now displaying B. The project checks here ran before the await and cannot protect that result. Abort/ignore stale recovery requests at fulfillment, or use project/request identity in the reducer; cover switching after recovery starts.

Reject results from superseded fetches.
If a user switches A → B → A, the first A request can finish after the new A request. Both guards accept it because state.projectId is A again. In particular, an old rejection can set state.error after the new request succeeds, causing the board to display an error instead of its loaded groups. Track the latest group-fetch request ID in pending, and require both the project ID and request ID to match in fulfilled and rejected. The board renders an error when state.error is set.
