Test refresh completion after sign-out.

Hold a refresh, sign out, then release a response with a different directory. Assert that the view remains signed out and directoryRelays remains unchanged. The current overlap test does not cover this transition.

Extend the relay shell tests around the held-read flow in “starts one read when
two reasons to read again land in the same moment” to hold a refresh, sign out
before it resolves, then release a response containing a different directory.
Assert the view remains signed out and directoryRelays remains unchanged; use
the existing sign-out and rendering mechanisms without changing unrelated
behavior.

Review comments at @DESIGN.md:
- Around line 4421-4424: Update the dashboard and sheet precedent entry to
explain which coding-agent design from the Paseo discussion they follow, or how
they differ; include the same clarification in the PR description. Preserve the
existing product precedents and avoid asserting a relationship that has not been
established.

Review comments at @scripts/relay-shell-browser-qa.ts:
- Around line 479-480: Update the createServer call in the account PC setup to
pass a herdrConfigPath located inside the temporary directory represented by
dir, ensuring the QA uses test-owned configuration instead of developer state.
- Around line 749-751: Use an unpaired PC in the mobile sheet capture setup in
the loop over page, width, and sheetOpen, replacing the Mac mini fixture with
one the approver cannot introduce so its dashboard row still exposes the Add
action.

Review comments at @src/components/AddPcSheet.tsx:
- Around line 54-59: Update addPcSteps so the current step is marked failed when
phase is "wrong", as well as when phase is "failed". Update the test that
expects the wrong-number step to remain running to expect failed instead.
- Around line 141-144: Update the phase handling in AddPcSheet so that when
account admission fails while the PC’s local-only pairing window is open, the
sheet follows a fallback that does not direct the user to seek remote account
approval. Preserve the existing guidance for other admission states.

Review comments at @src/components/RelayDashboard.tsx:
- Line 177: Update the approval notice in the RelayDashboard component to say
this device has not yet been paired, and direct users to select Join when that
action is available. Preserve the existing conditional behavior and translation
interpolation.
- Line 87: Update the account-fineprint text in RelayDashboard to distinguish
unlinked PCs from active account members and warn that older pairings may still
work; tell users to revoke those pairings on the affected PCs.

Review comments at @src/components/RelayMap.css:
- Around line 216-220: Update `.relay-map-host` to allow it to shrink within the
phone map and wrap long hostnames, preventing the route list from overflowing
horizontally.

Review comments at @src/components/RelayMap.tsx:
- Around line 72-77: Update the RelayMap layout controlled by DENSE_FROM, rx,
ry, cx, cy, and step so larger PC counts remain readable on desktop; increase
spacing or use a route-list fallback when the map cannot fit the PCs without
overlapping rings and labels.

Review comments at @src/components/RelayShell.tsx:
- Around line 273-280: Update the QR-instructions rendering condition in
RelayShell so it cannot render alongside the signed-out screen after account
becomes null; keep the signed-out view exclusive and preserve an available path
back to sign-in from the pairing flow. Retain the existing pairing behavior for
authenticated users and avoid changing unrelated screen conditions.

Review comments at @src/lib/relay/shell.tsx:
- Line 398: Update the refresh flow around dashboardUp() and showFront() to
record the signed-out state without replacing an active pairing screen,
preserving the code the user has entered. Guard state publication across the
store.list() await so a stale refresh cannot overwrite newer screen state.
- Around line 351-354: Coordinate the initial `account.listPcs()` request with
refresh reads so its response cannot replace a newer directory result; track
request ordering or freshness and apply `pcsOf`/`accountView` updates only when
the response is still current, preserving the latest refreshed PC rows.
- Around line 382-389: Update the refresh flow around account.session(),
account.listPcs(), and pcsOf() to verify that the directory response belongs to
the account currently displayed, not merely that accountView is unchanged.
Reconcile account changes across the asynchronous reads before publishing pcs
and directory, keeping linked-device metadata derived from the same account as
the directory.
- Around line 382-383: When account.session() returns undefined in the refresh
flow, update the view to signed out and redraw it instead of returning with
stale account rows and controls; preserve the existing accountView !== current
guard so obsolete refreshes do not change the view.
- Around line 393-395: Update the refresh flow around the failed-read branch
that assigns accountView so retained PC states are recalculated from their
last-sighting times even when directory reads fail. After 15 minutes without a
sighting, stop presenting a PC as Ready or “Seen lately” and remove its
live-wire indication, while preserving retained state for PCs still within that
window.
- Around line 384-389: The refresh flow updates the PC list without retrying
queued add approvals. After `account.listPcs()` and `pcsOf()` complete
successfully, invoke the existing queued-add retry mechanism, while preserving
the stale-view checks and ensuring failed refreshes do not trigger retries.

72-75: Trivial · Maintainability & Code Quality · Low value

Test sign-out on the mounted component.

Open the QR route, update the same RelayShell to signed-out props, and assert that pairing content is absent. The separate static renders reset addingPc, so they can miss pairing content left on the sign-in page when a pending directory read ends the session.

Review comments at @scripts/relay-shell-browser-qa.ts:
- Line 753: Update the mobile Add-sheet capture in the browser QA flow, anchored
by the `row(b, "Mac mini")` locator, to use a fixture that Desk PC A cannot
introduce to B. Keep the capture targeting an unpaired device whose dashboard
still shows Add, so it does not depend on Mac mini’s pairing state.
- Line 483: Update the stop function to wait for any in-flight mailbox pull to
settle before removing the temporary directory with rmSync. Preserve the
existing relay shutdown and PC stop behavior, and use the existing mailbox-work
tracking or synchronization mechanism rather than assuming pc.stop waits for
pulls.

Review comments at @src/components/RelayDashboard.tsx:
- Around line 126-128: Update the button-selection logic in RelayDashboard so a
fresh PC entry does not offer only Add when its PC-only pairing window is
closed. Provide access to the account-member Join flow in that state while
preserving Add when appropriate; use the existing pairing-window state to
determine which action is available.
- Around line 262-264: Update the row rendering in RelayDashboard so a failed
probe does not replace the PC’s directory state with Offline; keep the directory
state visible and show the probe result separately with a clear label. Preserve
the existing Ready filter, summary, and probe-status behavior.

Review comments at @src/lib/relay/shell.test.tsx:
- Around line 65-66: Update the afterEach cleanup to call visible with the
hidden state before jest.useRealTimers(), ensuring the page is hidden before
timers and globals are restored.

Review comments at @src/lib/relay/shell.tsx:
- Around line 397-403: Update the SignedOutError handling in the account
directory-read flow to reset the dashboard’s QR navigation when the session
ends. Ensure the signed-out view displays sign-in content alone, while
preserving the existing non-sign-out error handling and dashboard navigation
behavior.
- Line 403: Update showFront and its refresh call so a pending directory read
cannot replace the connected app: after awaiting store.list(), skip showing the
front view when an app is active for this refresh path. Preserve existing
showFront behavior for other callers.
- Line 403: In the refresh flow around `dashboardUp()` and `showFront()`,
recheck the current screen immediately before publishing signed-in refreshes,
including the initial `store.list()` read. If the user has opened code entry
while the read was pending, preserve that screen and its typed input rather than
rendering `showFront()`.
- Around line 404-406: Bound the directory read in the refresh flow identified
by the `read` promise and `refreshing` guard so a stalled request reports an
error and releases the guard for a later retry. Ensure a result arriving after
the bound has expired cannot update the displayed rows, and preserve the
existing cleanup behavior for the active read.
- Line 400: In the failed directory-refresh path that updates accountView,
recalculate each paired PC’s state from its retained last-seen timestamp so the
summary and map reflect whether it has crossed the offline threshold. Preserve
the timestamps and existing state rules; do not leave stale Ready or “Seen
lately” indicators when refresh requests fail.
- Line 354: Guard the initial `pcsOf(session, directory)` request so it
publishes results or handles errors only if `accountView` has not changed since
the request began. Prevent stale success or error paths from restoring the
signed-in dashboard or account rows after sign-out.
- Around line 384-389: Bind the refresh flow around `account.session()` to the
account represented by that session, so `listPcs()` and `pcsOf()` use the same
account even if another tab switches accounts mid-refresh. Update the stored
provider when the session’s provider changes, and retain the existing
`accountView !== current` guards to prevent stale refresh results from updating
the dashboard.
