📝 WalkthroughWalkthroughChangesThe application now loads and displays shared hubs and shockers. Control validation includes enablement, permissions, pause state, hub membership, and online status.

Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The PR adds shared-hub, live-control, and Windows tray behavior, but the current implementation still contains unresolved paths that can prevent startup, terminate the application, leave users authenticated with stale hub data, corrupt persisted control state, or leave controls stale or unusable.

330-425: 🎯 Functional Correctness | 🔵 Trivial | 💤 Low valueStale-frame age uses one timestamp for the whole pending map.
_pendingSinceTicksis overwritten on every park. A frame parked at t=0 for shocker A stays eligible when a later frame for shocker B arrives at t=1.9s, because the shared timestamp resets. The intent stated in the comment is per-frame staleness. Store the timestamp with each frame if exact per-frame ageing matters.The practical window is small, so treat this as optional.

Inline comments:
In `@Desktop/Backend/OpenShockApi.cs`:
- Around line 91-95: Update RefreshAllHubs to propagate failure when either hub
request is unsuccessful, using an explicit failure result or typed refresh
exception instead of returning normally. Make AuthService.Authenticate stop
before setting AuthState to Authed when refresh fails, and handle this refresh
failure separately in BackendHubManager.DeviceUpdate.
- Around line 154-181: Use a single private lock shared by SetShockerEnabled and
PruneDeadShockerOverrides to protect each OpenShock.Shockers read-copy-replace
update, and perform _configManager.Save() only after the corresponding mutation
completes inside the lock. Preserve the existing pruning and enablement behavior
while preventing concurrent updates from restoring removed overrides.
In `@Desktop/Bootstrap.cs`:
- Line 126: Update the tray initialization call in StartOpenShockDesktopServices
to avoid blocking startup and propagating tray failures: invoke
ITrayService.Initialize asynchronously without synchronously waiting for
completion, and observe/log failures without rethrowing them. Keep core service
startup independent of tray availability, including transient Explorer or
tray-window initialization failures.
In `@Desktop/Platforms/Windows/TrayIcon.cs`:
- Around line 132-143: Validate the LoadImageW result before populating the tray
icon data: when _hIcon is IntPtr.Zero, do not include NifIcon in data.uFlags so
Shell_NotifyIconW can create a tray entry without an icon, while preserving the
existing icon path when loading succeeds.
- Around line 183-207: Update the native callback method WindowProc and the
ShowContextMenu item-click path to catch exceptions from _onLeftClick,
ShowContextMenu, and items[command - 1].OnClick invocations so none escape
through DispatchMessageW; log the caught exceptions through the available
application logger when possible, while preserving the existing message handling
and return behavior.
In `@Desktop/Platforms/Windows/WindowsTrayService.cs`:
- Line 61: Update ShowMainWindow to execute through
Application.Current.Dispatcher, and obtain the target window with
FirstOrDefault() before accessing its handler or invoking ShowOnTop(). Update
Quit to use the same UI dispatcher so shutdown is marshaled from TrayIcon’s STA
callback thread.
In `@Desktop/Services/LiveControlManager.cs`:
- Around line 267-281: Update SweepLoop so each PruneConnectionsAsync invocation
is independently wrapped in a try/catch that logs non-cancellation exceptions
and then continues to the next timer tick. Preserve normal cancellation handling
and ensure one failed sweep cannot fault _sweepTask or stop future idle
eviction.
In `@Desktop/Ui/Pages/Dash/Components/StatePart.razor.cs`:
- Around line 56-69: Add disposed-state guards to OnParametersSetAsync around
both SubscribeAsync calls, matching the existing pattern in SharedHubsPart:
avoid creating subscriptions after disposal and clean up any subscription that
completes after disposal so _stateSubscription and _latencySubscription cannot
remain undisposed.
In `@Desktop/Ui/Pages/Dash/Components/UpdateLogout.razor`:
- Around line 61-65: Update the UpdateLogout flow around Updater.CheckUpdate and
UpdateAvailable so the success snackbar is not shown when CheckUpdateInternal
receives no release from GetRelease. Return or expose the check outcome and show
a neutral informational message for an unavailable release, while preserving
OpenUpdateDialog when an update is available.
- Around line 97-100: Update IsActive to consider a route active only when the
normalized current path exactly equals href or begins with href followed by a
path separator, preventing unrelated prefix matches such as settings-backup;
preserve the existing case-insensitive comparison and normalization.
- Around line 27-35: Update OpenUpdateDialog to use an atomic guard for the
check-and-set operation, preventing concurrent calls from opening multiple
dialogs. Ensure the guard is reset when ShowAsync fails as well as when
dialog.Result completes, and perform guard access consistently through the
chosen atomic mechanism.
In `@Desktop/Ui/Pages/Dash/SideBar.razor`:
- Around line 102-109: Make SideBar.razor (lines 102-109) and DashboardTab.razor
(lines 60-67) subscribe in OnInitializedAsync to
LiveControlManager.OnStateUpdated and Api.SharedOwners.ValueUpdated, invoke
StateHasChanged through InvokeAsync, and dispose both subscriptions in
DisposeAsync alongside _statusSubscription. In SharedHubsPart.razor (lines
166-205), confirm that parent re-renders rerun OnParametersSetAsync to reconcile
per-hub subscriptions; otherwise subscribe directly to
LiveControlManager.OnStateUpdated and dispose it appropriately.
In `@Desktop/Ui/Pages/Dash/Tabs/ShockersTab/ShockerComponent.razor`:
- Around line 76-81: Update PauseShocker so _wasChanged is reset after
PauseShocker completes, including when the API call fails, and trigger a
component re-render afterward so the pause toggle replaces the spinner. Preserve
the existing guard and pause-state request behavior.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Live-control state is now event driven, but no component observes LiveControlManager.OnStateUpdated. Connections are created lazily on the first control frame and pruned when idle or offline, so GetClient flips between null and a client without any parameter change in these components. LiveControlManager raises OnStateUpdated for exactly these transitions, and nothing in the provided code subscribes to it. The hub indicators, the latency text, and the shared-hub section therefore show stale state until an unrelated render occurs.
Desktop/Ui/Pages/Dash/SideBar.razor#L102-L109: subscribe toLiveControlManager.OnStateUpdatedand toApi.SharedOwners.ValueUpdatedinOnInitializedAsync, callInvokeAsync(StateHasChanged), and dispose both subscriptions inDisposeAsync.Desktop/Ui/Pages/Dash/Tabs/DashboardTab.razor#L60-L67: add the same two subscriptions and dispose them alongside_statusSubscription.Desktop/Ui/Pages/Dash/Components/SharedHubsPart.razor#L166-L205: once the parent re-renders onOnStateUpdated,OnParametersSetAsyncruns again and reconciles the per-hub subscriptions; confirm this path, or subscribe toOnStateUpdatedinside this component instead of relying on the parent.
