Issue

Navigate mode loses workspace selection shading when a saved SSH machine is configured. It also cannot move the selection between machines.

Problem

Navigation only considered the active machine, and the combined sidebar ignored the preview selection. Workspace IDs alone cannot distinguish identical IDs on different machines.

How did we fix it?

Herdr now highlights and reveals workspace selections across connected machines in compact, expanded, and mobile views. Enter activates the selected workspace; Escape cancels without switching. Offline machines are skipped, and stale selections cannot focus, rename, or close a replacement workspace. Renaming or closing a foreign workspace requires Enter first; other actions retain their active-machine context.

Verification

The new navigation test failed before because Enter targeted Local instead of the selected remote machine. It now passes alongside collision, invalidation, mutation-guard, and overflow tests. All 185 shell tests and 3,278 broader tests passed, plus Windows lint and docs checks. Three unrelated local checks remain excluded: one root-permission test and two handoff PID-discovery tests that assume an in-checkout target directory.

📝 Walkthrough

Walkthrough

The shell now supports workspace navigation across endpoints. Navigation targets include endpoint, workspace, boot, and snapshot-generation identity. Invalid targets cannot activate or modify remote workspaces. Collapsed, expanded, and mobile sidebars reveal and highlight the selected workspace. Tests cover stale targets, endpoint ordering, duplicate workspace IDs, overflow, and layout behavior. Documentation describes the navigation controls and action restrictions.

Suggested reviewers: ogulcancelik

Priority: ➖ Normal — Schedule the cross-machine workspace navigation change because it spans shell state, sidebar and mobile rendering, input actions, and stale-selection validation across connected machines.

Merge Risk: 🔵 Low · up to 0a5f1

A stale remote navigation preview can highlight a local workspace with the same ID after the remote machine disappears, making the sidebar selection misleading. This is a localized visual correctness issue that should be fixed before merge.

Greptile Summary

This PR makes workspace navigation endpoint-aware so saved-machine workspaces can be previewed, highlighted, revealed, and activated without confusing workspaces that share an ID across machines.

  • Introduces a navigation target containing endpoint, workspace, boot, and snapshot-generation identity.
  • Extends desktop and mobile sidebar selection and scrolling across connected machines.
  • Rejects stale navigation targets and prevents rename or close actions against foreign previews.
  • Adds regression coverage for highlighting, activation, ordering, overflow, stale snapshots, and fallback theme colors.
  • Documents cross-machine workspace navigation and action targeting.

Confidence Score: 5/5

The PR appears safe to merge; the endpoint-qualified navigation state, rendering behavior, and action guards are internally consistent and covered by focused regression tests.

No actionable new defect or outstanding repository-rule violation was established. Navigation ordering matches the displayed sidebar variants, stale targets are rejected before activation, and workspace actions cannot accidentally apply a foreign preview ID to the active endpoint.

Important Files Changed

@akbash-bot I can nav between selected active machine only with this change, I can't nav mode and move between all workspaces across machines? wdyt?

Yes—navigate mode currently moves only within the active machine. That predates this PR; this change restores the missing highlight without changing navigation targets. Previous/next-workspace actions already cross machines, so the inconsistency is real.

I think navigate mode should traverse workspaces across connected machines in sidebar order, moving only the highlight until Enter activates the chosen machine/workspace. The selection needs both machine and workspace IDs, and disconnected machines should remain unavailable. I would keep this highlight fix narrow and handle cross-machine navigation separately.

@akbash-bot lets fix / add the feature in this pr so nav mode works between machines too. feel free to change the pr description / title and implement both here

I can include it here. One safety decision first: Navigate mode already lets rename and close act on the highlighted workspace before Enter. Once the highlight crosses machines, those shortcuts need an explicit target policy.

I recommend requiring Enter to activate a foreign workspace before rename/close become available, rather than modifying a remote workspace whose contents are not visible. Should I use that rule?
