A workspace.reorder request that the pin-tier or group-section clamp turns into "stay put" (dropping a grouped member above its anchor, #13499) is a refused placement, but reorderWorkspace returns true for it, so the rejected branch in controlReorderWorkspace is never reached. These tests pin the refusal predicate the controller needs, including the cases that must stay successful: a clamp that still moves the row, and range normalization of an out-of-bounds index. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
reorderWorkspace returns true when the pin-tier or group-section clamp resolves a request to "stay put", so the rejected branch keyed on its result could never fire and #13499's case (a grouped member dropped above its anchor) still answered ok. controlReorderWorkspace now asks the reorder coordinator whether the placement is refused, returns .rejected before applying (a refused plan is a no-op), and reports the same refusal for dry runs. The rejected payload now carries window and workspace refs, dry_run, and requested_index alongside from/to, matching the ok result's fields. A clamp that still moves the row, and an out-of-range index clamped to the ends, stay successful, so ordinary `cmux workspace reorder` calls keep their exit status.

Re-reviewed at 491f96d, confirmed the earlier finding, and pushed a fix as two commits on this branch: 27fa499e3e (test) and 8ade81fa67 (fix). This branch had no activity since 11:16 UTC. Revert them if you want to take it another way.
The .rejected branch at 491f96d was unreachable
controlReorderWorkspace (Sources/TerminalController+ControlWorkspaceContext.swift) builds the plan with tabManager.workspaceReorderPlan(...) and returns .notFound if it is nil. It then calls tabManager.reorderWorkspace(tabId:toIndex: plan.toIndex) synchronously. That forwards to WorkspaceReorderCoordinator.reorderWorkspace with isDragOperation: false and explicitGroupId: nil. Its only return false sites are the unknown explicitGroupId check, which can't happen with nil, and a nil re-plan, which can't happen because the same planner just returned non-nil on the same state. Every other path returns true. So applied was always true.
The refusal in #13499 is a clamp, not a false. A grouped member dropped above its anchor goes through clampedGroupedMemberReorderIndex (WorkspacesModel+Ordering.swift), which pulls toIndex to firstIndex + 1. That equals fromIndex, and reorderWorkspace returns true at the plan.fromIndex == plan.toIndex early exit.
What the fix does
- New predicate.
WorkspaceReorderCoordinator.isRefusedWorkspacePlacement(tabId:toIndex:), plus a before/after form. A placement is refused when the caller asked for an in-range slot other than the current one and the pin-tier or group clamp resolves the plan to staying put.- Out-of-range indices are normalized first, so
index: 99on the last row is not a refusal. - A clamp that still moves the row is not a refusal. For example, an unpinned row at index 3 asking for index 0 below two pins moves to index 2 and stays
ok.
- Out-of-range indices are normalized first, so
- Controller.
controlReorderWorkspacechecks the predicate before applying and returns.rejectedwithout mutating. A refused plan is a no-op, so skipping the apply changes nothing. Dry runs now report the same refusal instead ofok. That is a change from the PR description ("Dry-run reorders remain successful"), made so a sidebar can preview a refusal. - Payload. The
rejectederror data now includesworkspace_ref,window_id,window_ref,dry_runandrequested_index(index form only), alongsidefrom_index/to_index. Before,case .rejected(_, let plan)discarded the window id. - The before/after target computation moved into a private
relativeReorderTargetIndexso the plan and the predicate share one implementation.
Behaviour change to call out
cmux reorder-workspace, tests_v2 callers and workspace.reorder automations now get an error instead of ok for a refused no-op placement. That is what #13499 asks for. Partial clamps and out-of-range indices keep their current ok result, so the break is limited to requests that previously did nothing and reported success. I found no test in tests_v2/ or tests/ that relies on an ok result for such a request, but I did not run those suites.
Verification
- Package tests don't run in CI.
CmuxWorkspacesis not in theswift-package-testspackage list inci-macos.yml, so CI cannot show the new tests red and then green. I ran them on a Mac instead (Xcode 27,swift test --package-path Packages/macOS/CmuxWorkspaces --filter WorkspaceCoordinatorTests):- At
27fa499e3e(test only): fails to compile,value of type 'WorkspaceReorderCoordinator<CoordinatorStubTab>' has no member 'isRefusedWorkspacePlacement'. The predicate is new API, so the red state is a compile failure, not an assertion failure. - At
8ade81fa67: 47 tests in the suite pass, including the three new ones. They cover the group-anchor refusal (index andbefore:forms), the pin-tier refusal, a partial clamp that still moves the row, a no-op request, out-of-range indices and an unknown workspace.
- At
swift build --package-path Packages/macOS/CmuxControlSocketsucceeds on the same Mac.- Update: I also pushed
1c459d238d, which merges main, andc96c79460a, a test.- Why the merge. The PR's merge-base, 4849743, predates the trusted Web complexity scripts. The required
Web complexitycheck reads its policy frompull_request.base.shaand failed with[[ -f trusted/scripts/ci/scope-web-complexity.py ]]on the first push. The merge applied cleanly. - The test.

- Why the merge. The PR's merge-base, 4849743, predates the trusted Web complexity scripts. The required
- The app-target files,
TerminalController+ControlWorkspaceContext.swiftandTabManager.swift, were only parse-checked by me. The macOS compile admission check will type-check them. App-host tests are skipped for this PR, so no test exercises the controller end to end.
Still open
- The sidebar's drawn order. The consumer in the report still would not re-sync.
ReorderableListdispatchesworkspace.reorderfire-and-forget and ignores the result, so the optimistic paint stays. That is item 2 of the issue's proposal, a re-sync token or reset. The PR body saysFixes #13499, and merging would close the issue with the reported symptom still present. I'd change it toRefs #13499. rejectedis a new error code with no docs entry.docs/events.mddocuments theokresult shape only.
Dogfood: in a tagged build, group two workspaces, then run cmux reorder-workspace --workspace <grouped member> --index <anchor index>. It should exit non-zero with rejected, and cmux list-workspaces should show the order unchanged. Also check that --index 999 on the last row still succeeds.

The socket coordinator turns a refused placement into a `rejected` error carrying the workspace and window ids and refs, from/to indexes, the requested index, and dry_run. CmuxControlSocket runs in CI's Swift package lane, unlike CmuxWorkspaces, so this pins the payload where CI executes it. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Fixes #13499.
A grouped member dragged above its anchor can stay painted at a position the host refused. The socket now distinguishes refused in-range placements from successful no-ops, and the JS renderer releases its local order and indentation preview when the drop animation finishes, even when host data never changes. A reactive
resetVersionoption lets custom sidebars explicitly reconcile without replacing row keys. Sidebar-owned optimistic item overrides must still be cleared by the sidebar.Refused index and relative requests return
rejectedin both normal and dry-run modes. Out-of-range requests and clamps that still move a row retain their previous behavior. The error is localized in all nine required macOS locales; socket payload semantics and the renderer reset are documented. No iOS behavior changes or relay allowlist changes.Validation: the renderer regression failed with three expectations before the fix; the constrained out-of-range regression failed with two. After repair, 19 SidebarJSRuntimeTests, 47 WorkspaceCoordinatorTests, and 15 ControlWorkspaceReorderTargetTests pass. A real TerminalController grouped-member regression is wired into cmuxTests; app-host test execution remains pending. Localization check: eight catalogs, nine locales, zero parity errors.
