📝 WalkthroughWalkthroughThe workspace client now exposes connection status and reconnect operations. The desktop app derives host reachability, displays diagnostic retry states, preserves workspace content during outages, and handles local-host startup and restart states. ChangesWorkspace host reachability
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds an unreachable-host overlay and periodic recovery attempts, but the current behavior can leave hidden workspace content reachable by keyboard or assistive technology and may restart slow connections before they finish, delaying or preventing recovery. Merge should wait for these issues to be fixed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

Tracks the shared event-bus socket per host and takes the workspace over after 10s of sustained loss, overlaying rather than unmounting so panes, scrollback and unsaved files survive the outage.

61-79: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAnnounce the connection status change to assistive technology.
The dot is
aria-hidden, and the adjacent text carries the meaning, so the state is not conveyed by color alone. That part is correct.The text still flips between "Reconnecting" and "Disconnected" while the screen stays mounted. Without a live region, a screen-reader user does not learn about the change. This screen exists to report changing connection state, so announcing it is valuable.

89-89: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueConsider passing the relay/local distinction in instead of re-deriving it from the URL.
WorkspaceProvideralready decides local versus relay withworkspace.hostId === machineIdand builds the relay URL from that decision.WorkspaceHostGatealso hasworkspaceandmachineIdin scope. This hook re-derives the same fact by pattern-matching/hosts/<id>in the URL string.The duplication is currently consistent, but it couples
describeFailureto the relay path shape. If the relay route changes, or if a relay base URL itself contains/hosts/, the hook selects the wrong copy and tells the user to restart a local host service that is not involved.An explicit parameter removes the coupling.

91-95: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winThe fixed 5s redial can repeatedly cancel a dial that is still in progress.
bus.reconnect()callssocket.reconnect(1000, "manual reconnect"), which closes the current attempt and starts a new one. Each attempt also runs the_whoownspreflight before the socket opens. If a dial needs more than 5 seconds to complete — cold host, slow relay region, high latency — this interval cancels it and restarts from the preflight, so the connection may never finish establishing while the screen is up.Two adjustments keep the responsiveness goal without the cancellation risk:
- Skip the redial while a dial is already in flight.

42-46: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueThe render reads a ref that only an effect writes.
Line 46 reads
lastLocalHostUrlRef.currentduring render, and the effect at lines 43-45 is the only writer. React documents refs as unsafe to read or write during rendering, because the render output is then not derived purely from props and state.The current flow still produces the right URL: the ref is only consulted after
activeHostUrlhas already turned null, and the write happened in an earlier commit. So this is a purity concern rather than a defect today. It does add a one-commit lag, and it makes the component's output depend on commit history instead of its inputs.State keeps the render pure and preserves the same behavior.

React 19 inert attribute boolean prop support aria-hidden focus containment
💡 Result:
React 19 officially includes native support for the inert attribute as a boolean prop [1][2]. Key implementation details and considerations include: Boolean Prop Behavior: In React 19, inert is treated as a standard boolean attribute [3]. This means you should pass inert={true} to enable it and inert={false} or inert={undefined} to remove it [4][5]. Passing an empty string (inert=""), which was a common workaround in older React versions, is now considered false and will not apply the attribute; this change may require updates to existing codebases [4][5][6]. Accessibility and Focus Containment: The inert attribute is now the recommended approach for focus containment and hiding content from assistive technologies, superseding older patterns that relied heavily on aria-hidden="true" [7]. Unlike aria-hidden, which primarily hides content from screen readers but may still allow programmatic focus, inert makes elements non-interactive (ignoring user input events) and prevents them from being focusable [8][7]. Migration Considerations: - Libraries and legacy codebases that previously used inert="" or other string-based workarounds will need to be updated to use boolean values (true/false) to maintain expected behavior [4][6]. - Because inert is more powerful than aria-hidden in terms of preventing interactions, it is now preferred for building modal dialogs and focus traps, often used alongside libraries like React Aria or Floating UI to manage focus stacks and containment effectively [9][10][8]. - Developers should be aware that applying inert to an ancestor of a focused element can trigger browser-level warnings or accessibility issues if not managed carefully [7]. Always ensure that focus is moved out of an element before marking that element (or its ancestors) as inert [7].

partysocket ReconnectingWebSocket shouldReconnect property public API retries exhausted
💡 Result:
In the PartySocket ReconnectingWebSocket implementation, the shouldReconnect property is a public boolean getter that indicates whether the WebSocket instance is currently in a state where it is permitted to attempt reconnections [1]. Regarding behavior when maxRetries is exhausted: 1. Historical Issue: Previously, when the configured maxRetries limit was reached, an internal lock (_connectLock) remained set to true, which prevented subsequent manual calls to the.reconnect method from successfully initiating a new connection attempt [2][3]. 2. Resolution: This behavior was identified as a bug [3] and fixed in early 2026 [4]. The fix ensures that the _connectLock is released when the maxRetries threshold is met [2][4]. 3. Current Behavior: As of the latest updates, calling.reconnect after maxRetries has been exhausted will correctly reset the internal retry counter (resetting it to -1) and initiate a new connection attempt, provided the instance is not otherwise closed or disabled [2][4][1]. If you are encountering issues with reconnection after retries are exhausted, ensure that your version of partysocket is up to date, as this was specifically addressed to allow developers to force manual reconnections (e.g., on window focus or user interaction) even after automatic retry limits have been reached [2][3][4].

Handle retries exhaustion as closed. In partysocket@1.3.0, shouldReconnect is public, but retries exhaustion does not set it to false. The close event therefore reports reconnecting after the final retry, so the retry UI remains busy indefinitely. Detect retries exhaustion and publish closed so the user can retry.

reported as closed rather than relying solely on socket.shouldReconnect. Detect
the terminal/exhausted retry condition in the Partysocket state, preserve
reconnecting for sockets still retrying, and ensure the resulting closed status
allows the user to retry.
- make covered panes inert so they stop taking focus behind the overlay - tell the user why a restart click did nothing without an active org - key the workspace provider on the workspace, not the host URL, so a host service returning on a new port swaps transport without remounting every pane

Summary
A v2 workspace whose host stops answering used to degrade into failing panes or a blank frame — the durable-object/relay connection dropping was never surfaced. This adds a takeover screen wired to the real connection.
packages/workspace-client— the shared per-host event-bus socket now tracksconnecting | open | reconnecting | closedplus the last_whoownsprobe, exposed asgetConnectionStatus/subscribeConnectionStatus/reconnect().useHostReachability— reads that status, retains the bus so it keeps dialling, and reports unreachable only after 10s of sustained loss. Keyed off the real data path rather than the cloudisOnlineflag, whose drift got this gate reverted twice before (fix(desktop): stop gating v2 workspace on flaky host online status #4430, revert: drop host-offline workspace gate from #4672 #4727).WorkspaceHostUnreachableState— revives the orphanedWorkspaceHostOfflineStateleft on disk by revert: drop host-offline workspace gate from #4672 #4727, with a live Reconnecting/Disconnected chip, a reason line derived from the relay probe (503 host not connected, 401/403 unauthorized, 502/504, routing, relay unreachable), and a Retry button.WorkspaceHostGate— overlays the screen instead of replacing the workspace, so panes stay mounted and terminal scrollback, unsaved editor documents and in-flight agent sessions survive a drop.WorkspaceLocalHostPendingState— replaces the blank<div>the provider rendered when the local host service has no port, with copy perhostServiceStatusand a button that restarts the service through the same coordinator call the tray menu uses.Two fixes came out of driving the running app over CDP:
activeHostUrlto null, which unmounted the whole workspace and left ~5s of empty pane before the service returned. The provider now holds the last known local host URL through a port gap. Measured: 45s across a kill and respawn, zero blank frames.Test plan
bun run typecheck(desktop) andbiome checkclean;packages/workspace-clienttests pass (13/13)Screens
Captured from the running app over CDP — real host name, real host ID, not mocked.
The takeover. Amber Reconnecting chip while the socket keeps dialling, Retry and Host settings. Note the right sidebar stays reachable outside the overlay, which is why there is no "browse workspaces" escape link.
Before — the blank frame this PR also fixes. A host-service restart nulled the host URL, which unmounted the whole workspace and left ~5s of empty pane with no explanation. Measured 7.5s–12.7s on a plain crash.
After the host returns. The screen lifts on its own — no reload, no navigation — 5.7s after the host is listenable again. (This workspace had no panes open, so it lands on the empty state.)
Summary by cubic
Surfaces a Host unreachable overlay for v2 workspaces to prevent blank frames and failing panes. Previously we unmounted or left panes failing; now after 10s of sustained loss we cover the workspace, keep panes mounted, and redial every 5s to cut recovery lag.
