Problem

On mobile, the home header replaces the T3 Code brand with "Reconnecting to " whenever any enabled environment is connecting. The connection supervisor retries forever, so one sleeping laptop keeps that label up for hours, even while another environment is connected and the app is fully usable. With every environment down it says "Reconnecting N environments" indefinitely, although the attempts have already failed. Reported in #19074.

Change

  • Header only reports an outage when nothing is usable. With at least one environment connected, the brand stays. Offline and "no environment connected" still take the title as before.
  • Thread sync is scoped to connected environments. A connection attempt also marks that environment's shell as synchronizing, so each background retry of the sleeping machine would otherwise flash "Syncing threads…". While an environment is connected, only a connected environment's sync shows it.
  • Failed attempts stop reading as "Reconnecting". Once an attempt has failed the header says " is unreachable" or "N environments unreachable" with the static icon. A first attempt still in flight keeps "Reconnecting…" and the spinner.
  • The unreachable environment is marked on its own rows. Thread and pending-task rows in the home list and the iPad sidebar already show the environment label and machine glyph when more than one environment is saved. For an unreachable environment that glyph becomes the existing wifi.slash glyph in the same muted tint, and the row's screen-reader label says so. Without this, hiding the header status would leave no sign that those rows are cached.

All of it is in apps/mobile; no contract, server, or shared client-runtime change.

Scope and approval

Bug report: #19074. It was filed alongside this PR and has not been triaged yet, so there is no maintainer approval to link.

The fix is limited to how the mobile home list presents connection state it already has. It adds no setting and does not change connection or retry behaviour. The row glyph is part of the same problem, not a separate feature: it is where the unreachable state goes once it leaves the header.

Not included: the Connections settings copy, the environment filter menu, the archived threads screen, and web or desktop.

Verification

Reproduced on an Android 17 emulator (Pixel 9) with the mobile dev client against two environments: "homelab", connected, and "laptop", whose server is stopped. Before is main at 511d20c; after is this branch. Same device, same data.

Before After
One environment connected, one unreachable Before: header reads Reconnecting to laptop After: brand header, laptop rows show the wifi-slash glyph
No environment reachable Before: header reads Reconnecting 2 environments After: header reads 2 environments unreachable

Observed after: with homelab connected the header shows the brand and only the laptop rows carry the glyph; with both down the header reads "2 environments unreachable" and every row carries it.

Focused tests, all passing (20 tests):

vp test run apps/mobile/src/features/home/workspace-connection-status.test.ts \
  apps/mobile/src/state/workspaceModel.test.ts \
  apps/mobile/src/state/workspace-connection-atoms.test.ts

They cover the header staying hidden while another environment is connected, ignoring a retried environment's pending shell, the unreachable wording, and the mixed first-attempt case. The mobile typecheck passes.

Not checked:

  • iOS and the iPad sidebar. Only Android was run; the logic is shared.
  • A slow, hanging connection attempt. The stopped server refuses connections immediately, so the "Syncing threads…" flash during a retry was established from the code (connectionProjectionPhase maps connecting to synchronizing) and is covered by a unit test, not seen on a device.
  • Screen readers. The row label was checked through the accessibility tree, not with TalkBack or VoiceOver.

The laptop rows in these screenshots sit 8dp further out than the homelab row. That is a separate, existing layout bug and is fixed on its own in #19076.

Approvability

Verdict: Approved at 4caaf97

Macroscope's review found this PR approvable — This is a focused mobile presentation bug fix that prevents stale reconnect status from overriding a usable workspace and marks affected cached rows locally. Connection behavior remains unchanged, the state logic is localized, and the relevant scenarios have focused test coverage.

📝 Walkthrough

Workspace state now identifies unreachable environments and tracks syncing connected environments. The home connection status reflects these states, and home and thread lists show unreachable indicators for affected environments.

Some users may not see or hear that a single saved environment is unreachable. This is a bounded presentation issue; merging carries low risk.

Explanation

The changes satisfy the coding requirements in directly linked issue #19074. workspace-connection-status.ts keeps the brand when a connected environment exists, limits syncing status to connected environments, and reports failed attempts as unreachable. environmentIsUnreachable drives wifi.slash row glyphs and accessibility labels for affected thread and pending-task rows. Focused tests cover connected, retrying, unreachable, and first-attempt cases.

Full details: Out of Scope Changes check

Explanation

The changes stay within #19074. They modify mobile home and sidebar presentation, related workspace state projection, and supporting tests. The reviewed scope contains no server, contract, shared client-runtime, settings, filter-menu, archived-thread, web, or desktop changes. The row glyph and accessibility updates directly support the issue after the header no longer shows the unreachable environment.

The home header swapped the brand for "Reconnecting to <environment>" while
any enabled environment was connecting. The supervisor retries forever, so one
sleeping machine kept that label up indefinitely even with another environment
connected and usable.

The header now reports connection state only when nothing is usable, says
"unreachable" once an attempt has failed, and reports thread sync only for
connected environments. Rows of an unreachable environment swap their machine
glyph for a wifi-slash glyph instead.

Preserve unreachable status when the environment label is hidden.

When one saved connection exists, environmentLabel is null but environmentUnreachable remains set. In both row types, the current conditions suppress the unreachable glyph and accessibility text. The metadata container also needs to render when the environment is unreachable.

Use the unreachable flag for the glyph and use "this environment" as the accessibility fallback.

Claude Opus 5.5 responding on behalf of @tris203

Intentional, so no change. With a single saved connection, an unreachable environment means nothing is usable: hasReadyEnvironment is false, so the home header already reads " is unreachable" (workspace-connection-status.ts, shouldShowWorkspaceConnectionStatus / connectingEnvironmentsLabel). The row glyph only stands in for the header when another environment is connected, which needs more than one saved connection. That is also when rows show the environment label and machine glyph at all. Adding the marker to every row in the single-environment case would repeat the header on each row.

Grok responding on behalf of Julius.

Thanks for this! #19074 is now fixed on main by #21388, which keeps the home brand visible while a secondary environment retries and scopes sync state to connected environments. Closing this as superseded. If any of the extra changes here (the thread sidebar and thread list bits) still fix something on top of #21388, feel free to open a smaller follow-up PR against current main.
